[002] Not applicable SEQUENTIAL LISTING
[003] Not applicable. BACKGROUND OF THE INVENTION FIELD OF THE INVENTION
[004] The present description generally refers to a method and system for the distribution of a composition, and more particularly, to a distributor that generates a plurality of usage and effectiveness indicators as a result of the contact of the composition and the interaction with the distributor. DESCRIPTION OF THE BASICS OF THE INVENTION
[005] Users of consumer products usually buy a composition to perform a specific household task. For example, a user may wish to spray a pest control agent inside or outside a home to control pests. Alternatively, a user can purchase an air deodorizing device to puncture and / or deodorize a home. In some cases, it is desirable to distribute a composition immediately, for example, by distributing the pest control composition to a plague to exterminate the plague. In other cases, it is desirable to distribute a composition over an extended period of time to achieve a desired result, for example, to distribute a perfumed composition in a home environment to continuously provide a pleasant odor. In other cases, it is desirable to distribute a composition that provides both an instant result followed by an extended action of the same or another composition to achieve a longer term result.
[006] Unfortunately, many consumer compositions are just instant-acting compositions that are effective for a short time after being released from a reservoir or are passive, continuous-acting compositions that are effective for extended periods of time. of a preloaded substrate. Each system has advantages over the other. For example, active systems allow a user to quickly release a desired amount of an insecticide or fragrance into the environment to repel insects or overcome a strong odor. However, these peaks in the intensity of the composition are usually quickly reduced. On the other hand, passive systems typically have a relatively continuous emission of a composition with a more subtle reduction in the intensity of the composition compared to active systems.
[007] Some have sought to combine active and passive systems to take advantage of the controlled release of active systems and the sustained release of passive systems. For example, in U.S. Patent No. 4,341,348, a delivery device is described and delivers a jet directly into the air and into an absorbent element. The dispensing device includes an aerosol container and a lid arranged on top of the aerosol container. The cover includes a ventilated cylindrical side wall and a ventilated upper part. A plunger element engages a valve stem in the container and extends through the top of the cap. The plunger includes two doors formed on opposite sides of it. Two absorbent carrier elements are arranged within an upper part of the cap around the plunger element. The carrier elements are substantially semicircular in cross section and are spaced around the plunger in such a way as to create two diametrically opposed passages. Upon activation of the plunger element, the fragrance is released from the doors and through the opposite passages into the atmosphere. The lid can also be rotated by 90 degrees so that the doors and passages do not line up, so that when the plunger is activated the jet is released from the doors directly into the carrier elements. Additional ports can be provided on the plunger so that the jet can be released through the passages and to the carrier elements simultaneously.
[008] Another device described in U.S. Patent No. 4,726,519 simultaneously sprays an air-in-air treatment composition for instant air treatment and for recharging an absorbent element for continuous air treatment. The device includes a cap for an aerosol container that includes a cylindrical ventilated wall and a trigger button with a passage in communication with a valve stem of the aerosol container. The absorbent element is disposed within the lid. When the device is activated, the air treatment composition passes a plurality of outlets formed in the passage before being discharged through a spray hole and into the air. The plurality of outlets directs a part of the air treatment composition to the absorbent element for the subsequent passive treatment of air. A preferred embodiment includes four exits spaced at 90 degree intervals around the passageway. Alternatively, the outlets can be formed on the valve stem of the aerosol container instead of in the passage.
Similarly, an additional vapor delivery device illustrated in U.S. Patent No. 7,887,759 includes multiple delivery mechanisms for fragrance release. The dispensing device includes a continuous dispensing mechanism with an emanation element in communication with a reservoir, for the distribution of a passive and continuous release of the fragrance. The dispensing device also includes an on-demand dispensing mechanism for dispensing an instant burst of fragrance. In addition, activation of the on-demand delivery mechanism produces a second passive and continuous release of the fragrance by depositing a part of the fragrance burst on the continuous delivery mechanism or a second surface. The combination of the first and second passive releases creates a fragrance release that has a greater intensity than the fragrance released by the continuous delivery mechanism alone.
[010] Another system described in US Patent No. 6,610,254 includes an aerosol container that is designed to be used immediately (for example, actively) and uses an additional component provided in the form of a separate gel cartridge to provide passive diffusion . This system requires the use of two separate components to perform the passive and active diffusion, which results in the user needing to purchase the separate components to match their active and passive distribution needs. The consumer also needs to monitor both components for refueling to ensure that the system is operating correctly.
[011] A particular obstacle with respect to both active and passive distribution systems is the notification to the user that the composition has been actively released together with notification that the composition continues to provide the desired effect for a period of time after the initial release (that is, passive release). Some prior art systems provide an initial indicator that the composition is in use when the system is turned on for the first time, configured or otherwise provided to the user in its initial use stage. In some cases, notification is provided to the user through an audible indicator. In other cases, notification is provided to the user through a visual indicator.
[012] Difficulties arise through the use of some visual or audible indicators, however. For example, in some cases, audible and visual indicators are transient and generally do not provide the user with any indication of continued effectiveness. In other cases, the visual indicators are electronic and provided in the form of an LED or other light. In these systems, the LED is typically supplied as a very small lamp that flashes rapidly to indicate usage. Lamps can be difficult for some individuals to see due to lamp size restrictions. In addition, lamps are more expensive and add a complication and cost to the system's manufacturing process.
[013] In other systems, a jet can be generated during activation. The jet can provide a visual indicator of the active emission status of the system. Unfortunately, however, many systems spray inside a housing that hides the jet, and in this way, the visual indicator is hidden.
[014] Some prior art systems have attempted to overcome the problems mentioned above by implementing a usage tip associated with the system. In these systems, the usage tip is provided to indicate the use of a volatile element throughout its life cycle. However, many usage tips known from the prior art only monitor the passive aspects of the system and do not provide any indication or monitoring of an active aspect of the system.
[015] In addition to the indicators provided by the system, an important aspect for a user's perception of the system's effectiveness is the appearance and type of substrate being used in the system. In particular, in systems using a substrate having a non-absorbent appearance, users can perceive that a composition will not be absorbed into the substrate when applied, and therefore will not continuously provide passive diffusion after that. In fact, a user's perception of the absorption properties of solid substrates, correct or not, provides an indication that the substrate will not be efficient in the passive release of the composition. Such systems can also result in inefficiency or excessive use due to the perceived need by the user to overcome the deficiencies of the system by instantaneous over-spraying.
[016] In contrast, a fabric, or cardboard-like substrate conjures up a completely different perception for a user. For example, most users inherently understand that a composition sprayed onto a fabric-like substrate will first absorb into the substrate and provide an immediate active burst while also continuing to provide an extended emission after the composition is initially sprayed onto the substrate. A common example familiar to many is when the perfume is sprayed on clothing. The perfume provides an aromatic burst at the time of spraying and the sprayed clothing continues to release the aroma during the day, or for a period of time after the initial spraying period.
[017] Therefore, there is a need to create a system that provides both active and passive diffusion from a single component and forces one or more indicators of active and passive emission states. Most preferably, such a system is non-electronic to simplify manufacturing and reduce costs. In addition, such systems are also simpler to use and maintain.
[018] There is also a need to provide such a system that minimizes the need for multiple refills. More particularly, it is preferred that such a system requires only a single refill that supplies a composition for both active and passive use.
[019] There is additionally the need to provide a system that allows the user to easily activate the system to provide both active and passive diffusion through a single step. Additional advantages can be realized when the user wants to replenish the passive diffusion aspect of the system after exhaustion. In particular, the user simply activates the system a few more times, which results in the system being replenished and again providing both active diffusion and passive diffusion through a single activation step.
[020] There is also a need to provide efficient visual indicators for the user. More particularly, it is preferable for a system to use parts that perform passive and active diffusion to provide visual indications of effectiveness themselves. In such systems, parts are reduced and the communication of system operation and efficiency is simplified and intuitive for a user. SUMMARY OF THE INVENTION

[075] The present description is generally aimed at distributors for the distribution of a fluid medium. For purposes of discussion here, a particular illustrative modality will be explained, using a composition containing an aerosol-based volatile asset. However, it should be understood that the systems described, regardless of whether they are described with respect to an aerosol, a volatile element, a composition, etc., are not limited and can be used with any number of liquids or fluids, which can be discharged by one or more of an aerosol system, a compressed gas system, a pump-type sprayer system, or any other means known to those skilled in the art.
[076] The dispensers described here can be used as standalone devices, which can be located on a table, shelf or other flat surface. Alternatively, dispensers can be used as a portable device. With reference to figures 1 to 3, a particular embodiment of a dispenser 100 is illustrated and generally includes a base 102 designed to accommodate a container 104 with a fluid medium (not shown). The dispenser 100 additionally includes a sleeve 106 which extends upwardly from the base 102.
[077] The distributor 100 is generally designed to be operated manually through pressure applied to base 102. Base 102 therefore acts as (or includes) a drive mechanism for discharging the fluid medium through it and can include any number of activators or triggers to perform the distribution. In particular, during actuation, the fluid medium sprays inside the sleeve 106 at a specific angle, which causes a plurality of droplets to interact with the sleeve 106 to provide different functionalities for the distributor 100, such as active and passive emission. of a volatile composition or material. More particularly, some droplets are released immediately to form a trail that is initially present within and / or above the sleeve 106 to provide instant active emanation, and other droplets are absorbed into the sleeve 106 to provide passive emanation over a period of time. extended.
[078] With specific reference to figure 3, base 102 is defined by a lower housing 108 which is releasably attached to an upper housing 110. The lower housing 108 and the upper housing 110 are in communication when the distributor 100 is being used and are designed to be separated from one another when container 104 is added or removed. The base 102 additionally acts as a manual override mechanism for the distributor 100 due to its unique construction, which is described in detail below.
[079] Each of the components of the dispenser 100, including the base 102, can have a generally square shape with a slightly rounded curvature printed on each side of the same, when viewed from above or below (see, for example, figure 6), but it can also have a circular, elliptical, triangular shape or any other geometric shape with the properties described here.
[080] Base 102 can be constructed from any suitable material, such as plastic, a polymer, a fabric, a non-woven substrate, such as a non-woven PET substrate, a cellulosic material, a metal, glass, wood , stone, rock or combinations thereof. Additionally, the materials may include combinations of manufactured, natural, and / or recycled or reused materials. A consideration for the consumer is the appearance of the base 102, which preferably has a natural appearance, such as a smooth or textured rock or pebble. Curvy sides can also be provided with a natural looking pattern, such as a wooden knot, a stone pattern with or without inclusions, a fossil pattern, etc.
[081] As best illustrated in figures 4 to 7, the bottom housing 108 of the base 102 includes a substantially flat side wall 111 defined by an outer surface 112 and an opposite inner surface 114. The outer surface 112 is designed to be positioned adjacent to a support surface (not shown) and the inner surface 114 is enclosed through the upper housing 110 when the dispenser 100 is in use.
[082] With reference to figure 4, the outer surface 112 of the lower housing 108 includes two opposite curved grooves 116 formed there. Grooves 116 define finger grips to assist the user in grasping the lower housing 108 when the user separates the lower housing 108 from the upper housing 110. The print curvature in the grooves 116 is designed to correspond to the natural placement of a user's fingers (for example , a thumb arranged inside a groove and a forefinger and middle finger arranged together in the opposite groove). A plurality of feet 118 optionally extends from the outer surface 112 to create a light space between the base 102 and a support surface.
[083] As shown in figures 4, 5 and 7, the lower housing 108 additionally includes a side wall of ascending extension 120 encompassing the perimeter. The sidewall 120 is slightly rounded and is defined by corners with wings 122 and a plurality of flexible U-shaped elements of substantially ascending extension 124. The corners with wings 122 are slightly angled and are arranged in all four corners of the lower housing 108. The flexible U-shaped elements 124 are generally arranged centrally along the side wall 120 and are spaced internally from each of the corners 122. The elements 125 each include a substantially U-shaped flange 126 defining a substantially square opening 128. A horizontal section 130 of flange 126 is slightly tapered to provide an orientation function when the upper housing 110 is attached to the lower housing 108.
[084] As seen in figure 5, the lower housing 108 also includes two arched and raised protrusions 132 extending upwardly from the inner surface 114. The protrusions 132 define the limits of the grooves 116 formed on the outer surface 112 of the side wall 111. A centrally arranged pedestal 134 extends upwardly from an approximate central point on the inner surface 114. Pedestal 134 is substantially cylindrical and includes a circular opening 136. The opposite sections of protrusions 132 are in communication with pedestal 134 forming a contiguous structure along the inner surface 114 of the lower housing 108.
[085] A function of pedestal 134 is to act as a receiving and holding mechanism for container 104. To provide suitable support for container 104, pedestal 134 and the corresponding opening 136 are preferably formatted to match the shape of container 104. In the illustrated embodiment, pedestal 134 is substantially cylindrical and opening 136 is circular to correspond to a cylindrical container 104. Additionally, pedestal 134 preferably includes a suitable height dimension H1 (see figure 5) as measured from the inner surface 114 to the upper edge of pedestal 134 with respect to a height dimension H2 (see figure 16) of container 104 to provide sufficient support. In one embodiment, the ratio of H1 to H2 is about one to about one. In another embodiment, the ratio of H1 to H2 is about one to about two. In an additional embodiment, the ratio of H1 to H2 is about one to about three. In another embodiment, the ratio of H1 to H2 is about one to about four. In an additional embodiment, the ratio of H1 to H2 is greater than about one.
[086] Pedestal 134 additionally includes a dimension of diameter D1 sufficient to accommodate container 104. In one embodiment, the diameter is between about 10 mm to about 100 mm and in another embodiment it is between about 16 mm to about 67 mm. In another embodiment, the diameter is about 20 mm. The diameter D1 of the pedestal 134 is slightly larger than the diameter D2 of the container 104 so that a space is formed between the container 104 and an inner surface 140 of the pedestal 134. In one embodiment, the space is less than about 10 mm. In another embodiment, the space is less than about 5 mm. In an additional embodiment, the space is less than about 2 mm. In other embodiments, the pedestal 134 can be omitted and other retention mechanisms can be used to support the container 104 in the lower housing 108.
[087] Pedestal 134 is provided internally from the perimeter of the lower housing 108. More particularly, pedestal 134 is spaced from the side wall 120 of the lower housing 108 by a distance of between about 2 mm to about 60 mm around of the circumference thereof, as measured from an external surface 142 of the pedestal 134 to the side wall 120. In one embodiment, the pedestal 134 is spaced from the side wall 120 of the lower housing 108 by a distance of at least about 24 mm .
[088] Turning now to figures 8 to 10, the upper housing 110 is defined by a guard 150 with a dome 152 integral with it and projected upwards from it. The upper housing 110 is designed to act as a manual override mechanism (for example, push button) through its interaction with the container 104 and the lower housing 108. The upper housing 110 also acts to cover the internal components of the dispenser 100 such as container 104.
[089] Shield 150 includes four slightly rounded lower side walls 154 with beveled top edges 156. Dome 152 is recessed from edges 156 and includes four side walls of upward extension 158 that end on a convex top surface 160. In the mode shown in figures 8 to 10, the side walls 158 of the dome 152 are similar in shape to the lower side walls 154 of the guard 150. The recessed orientation of the side walls 158 of the dome 152 creates a recess 162 extending around it. In particular, the recess 162 extends between the edges 156 of the lower side walls 154 and side walls 158 of the dome 152.
[090] The recess 162 is preferably dimensioned to accommodate the sleeve 106, as described in greater detail below. In the embodiment shown, the recess 162 includes a depth dimension of about 2 mm and a width dimension of about 1 mm. In other embodiments, the recess 162 includes a depth dimension of about 25 mm and a width dimension of about 1 mm. In additional embodiments, the recess 162 includes a depth dimension of 0 mm and a width dimension of 0 mm, that is, the recess is absent. However, it is anticipated that the depth of the recess 162 can be from about 0 mm to about 25 mm and the width of the recess can be from about 0 mm to about 25 mm.
[091] Still with reference to figures 8 to 10, the dome 152 additionally includes a circular opening 164 that extends through the upper surface 160. The opening 164 is dimensioned to receive a trigger nozzle 166 (see figure 11) that provides communication by fluid between the container 104 and the external environment to the base 102, as described in greater detail below.
[092] The lower side walls 154 of the guard 150 define an opening 168 (see figure 9) that receives the lower housing 108 when the distributor 100 is in use. As shown in Figure 9, a plurality of elongated protrusions 170 extend outwardly from an inner surface 172 of the guard 150 and four stabilizing ribs 174 project outwardly from an inner surface 176 of the dome 152. The protrusions 170 each includes two opposite angled end parts 178 connected via a substantially flat part 180. In the embodiment shown, two protrusions 170 extend outwardly from the inner surface 172 of each side wall 154, defining eight protrusions in total. The protrusions 170 are spaced from each other by a distance of about 0 mm (for example, when there is only one rib) to about 60 mm.
[093] As illustrated in figures 9 to 11, protrusions 170 are arranged centrally and designed to interact with U-shaped elements 124. In particular, the interaction between protrusions 170 and the square opening 128 of each of the non-U-shaped elements 124 reliably combines the lower housing 108 with the upper housing 110 when the protrusions 170 are disposed within the openings 128. Although the protrusions 170 are elongated and are provided with a space between them, it is envisioned that the protrusions 170 having other shapes and dimensions can be provided in the protection 150 which are consistent with openings of different shapes 128 of the U-shaped elements 124 to realize the releasable combination of the lower and upper housings 108, 110.
[094] As best illustrated in Figure 10, the four rigid ribs 174 project outwardly from the inner surface 176 of the dome 152. The ribs 174 extend internally from the corners of the dome 152 towards a central part before terminating in an area adjacent to the center of the dome 152. Ribs 174 provide stability to the dome 152 and extend substantially the entire length of the dome 152. Ribs 174 also act as a guiding mechanism when the lower housing 108 of the base 102 is being combined with the upper housing 110. In particular, a space 177 is formed between the ribs 174 which are provided in the contour of the container 104 so that the container 104 can contact the ribs 174 and slide between them during the insertion.
[095] An elevated circular surface 181 (see figure 9) projects into the dome 152 and encompasses the circular opening 164 that extends around it. The surface 181 is flat to accommodate a portion of the container 104 as described in greater detail below. As best illustrated in figure 12, opening 164 is sized to receive a portion of the trigger nozzle 166.
[096] Now, with reference to figures 12 to 15, the actuating nozzle 166 is provided in the form of a conical body 182 with a collar 184 that encompasses the body 182 around a lower edge thereof. The nozzle 166 additionally includes a plurality of depressions 186 on an external surface 188 thereof and a plurality of outlet ports 190 arranged in and extending through the depressions 186. The outlet ports 190 each provide a fluid path and act as an outlet for a fluid medium being emitted from the dispenser 100. Each outlet port 190 is substantially circular and divides the composition as it leaves base 102 into a plurality of streams, for example, 2, 3, 4, or 6 chains.
[097] As shown in figure 12, the exit doors 190 are arranged equidistant from each other around a vertical geometric axis B1 defined by a central point of the actuator nozzle 166 and the longitudinal geometric axis B2 of the container 104 (see figure 16) both radially and circumferentially. However, with reference to figure 16, it can be seen that the exit ports 190 can be radially equidistant, but circumferentially not equidistant. In fact, any number of arrangements is contemplated based on the desired flow characteristics of the distributed medium.
[098] In the modality illustrated in figures 12 to 14, four exit doors 190a-190d are presented. In the embodiment illustrated in figure 15, six outlet openings 190e-190j are shown. Output ports 190 are each defined by a diameter parameter of between about 0.1 mm and about 1 mm. In other embodiments, outlet ports 190 are each defined by a diameter parameter between about 0.2 mm and about 0.7 mm. In other embodiments, outlet ports 190 are each defined by a diameter parameter of about 0.25 mm. In additional embodiments, outlet ports 190 are each defined by a diameter parameter of about 0.4 mm. In other embodiments, the exit ports 190 are each defined by a diameter parameter of about 0.5 mm. In additional embodiments, outlet ports 190 are each defined by a diameter parameter of about 0.6 mm. In a preferred embodiment, the exit doors 190 have a uniform cross section and diameter (or width) throughout them. In other preferred embodiments, the exit ports may have a cross-section and / or non-uniform diameter (or width) across all or part of them. In addition, in other preferred embodiments, one or more of the parts may have variable cross-section and / or diameter (or width) parameters.
[099] Each exit port 190 is oriented at an angle with respect to a horizontal plane P defined by collar 184 (see figure 12). Generally, the plane P can be viewed as a plane orthogonal to the vertical geometric axis B1. In particular, the outlet openings 186 are arranged at an angle so that a large part (for example, greater than 75%) of the fluid medium will spray in a cone shape at an angle of more than about 30 degrees with respect to the plane P. Such a cone angle is a factor for realizing various indicator characteristics of the distributor 100 described here. In particular, the cone angle determines the area that is initially moistened through direct contact with the jet. A small cone angle (for example, less than about 30 degrees) results in a small area exposed to the jet and a thicker layer of sprayed medium in sleeve 106. In contrast, a larger cone angle (for example, greater than or equal to about 30 degrees) results in a larger spray area and a thinner layer of medium sprayed on sleeve 106. In some cases, the cone angle is minimized to create a deeper, more concentrated wet area (ie , visual indicator) on sleeve 106. In other cases, a larger section of sleeve 106 will be contacted using a larger cone angle.
[0100] Exit ports 190 can each have a cone angle of between about 30 degrees and about 80 degrees. In another embodiment, outlet ports 190 may each have a cone angle of between about 40 degrees and about 70 degrees. In an additional embodiment, the outlet ports 190 can each have a cone angle between about 50 degrees and about 70 degrees. In a specific embodiment, outlet ports 190 each have a cone angle of about 45 degrees. In another embodiment, outlet ports 190 each have a cone angle of about 50 degrees. In an additional embodiment, outlet ports 190 each have a cone angle of about 55 degrees. In a different embodiment, outlet ports 190 each have a cone angle of about 60 degrees. In fact, it is envisioned that a cone angle can be anywhere between about 1 degree and about 180 degrees, more preferably about 5 degrees and about 90 degrees, more preferably about 10 degrees to about 50 degrees, and more preferably between about 10 degrees and about 20 degrees.
[0101] As illustrated in figure 13, the exit ports 190 extend through the body 182 and are in communication with a chamber 192 formed by them. The chamber 192 is designed to interact with and receive the fluid medium distributed by the container 104 and to direct the medium through the outlet ports 190.
[0102] In order to distribute the fluid medium efficiently, the chamber 192 has a volumetric capacity of about 0 mm3 to about 216 mm3. In one embodiment, the volumetric capacity of chamber 192 is about 27 mm3. In another embodiment, the volumetric capacity of chamber 192 is about 64 mm3. In an additional embodiment, the volumetric capacity of chamber 192 is about 125 mm3. In some embodiments, it is preferable to minimize the volume within chamber 192 to approach or reach zero.
[0103] In one embodiment, the trigger nozzle 160 may have a conical opening defined by a cone angle, as discussed here. In other embodiments, the trigger nozzle 160 may have a flat surface with an orifice. It is also contemplated that the trigger nozzle 160 may include one or more spray inserts known in the art that can print a spray pattern formatted such as a fan shape, oval shape, square shape, donut shape, and the like. In addition, depending on the specific design of the nozzle 160, the direction of the jet being emitted from the nozzle 160 can be adjusted accordingly. For example, the jet can be sprayed perpendicular to the plane P (see figure 12). In another embodiment, the jet can be distributed perpendicularly to the sleeve upwards and downwards (for example, 60 degrees upwards and 60 degrees downwards).
[0104] In one embodiment, one or more exit ports 190 have a diameter of about 0.5 mm. In another embodiment, one or more exit ports 190 have a diameter of about 0.25 mm. In an additional embodiment, one or more of the exit ports 190 have a diameter of about 0.75 mm. In an additional embodiment, one or more of the outlet ports 190 have a diameter of about 1 mm. It is also contemplated that an exit door can have a diameter of between about 0.1 mm and about 2 mm. It should be appreciated that as the size of the outlet port increases, a more significant part of the fluid product will be deposited on the sleeve 106, assuming that the distribution pressure of the container 104 has not been adjusted to accommodate the size outlet ports. larger 190. Alternatively, using the smaller sized exit doors (for example, less than about 0.4 mm) will cause more fluid product to be distributed within the track, as opposed to sleeve 106. The trigger nozzles 160 having larger exit ports 190 can be used in other modalities. However, in these embodiments, the product medium may need to be discharged at a greater angle to the longitudinal geometric axis of the container 104 to effectively deposit the fluid medium in the sleeve 106.
[0105] Now, returning to figure 16, the dispenser 100 is designed to hold and support a container 104 and release a fluid medium (not shown) during actuation. In one embodiment, container 104 is an aerosol container. Aerosol containers are generally well known to those skilled in the art. In one embodiment, the aerosol container 104 comprises a body 200 with an upper end 202 and a lower end 204. A mounting cup 206 is disposed above a neck 208 of the aerosol container 104. The body 200 is generally cylindrical and is defined by a cylindrical wall 210. A valve assembly (not shown) disposed within an upper part of the aerosol container 104 includes a valve stem 212 which extends through a pedestal 213 of the container 104.
[0106] A valve set suitable for use in container 104 is a 185 mcl valve supplied by Aptar under model number MV002006. Another valve set suitable for use on container 104 is a 300 mcl valve supplied by Summit. The valve used in container 104 preferably emits at least about 100 ml per jet, and container 104 preferably includes a composition sufficient for about 65 to about 105 jets per container.
[0107] Still with reference to figure 16, the valve stem 212 is a cylindrical tube having a passage 214 arranged longitudinally through it. A distal end 216 of valve stem 212 extends upwardly and away from pedestal 213, and the mounting cup 206 and a proximal end (not shown) are disposed within the valve assembly.
[0108] A stem fitting 218 (see figure 3) is ideally used in conjunction with the trigger nozzle 166 to provide an interface between the valve stem 212 of the container 104 and the chamber 192 of the trigger nozzle 166. The rod 218 includes a disk-shaped body with a tapered sidewall projecting upwardly from it. The conical side wall is arranged centrally in the body and defines a fluid passage in the body.
[0109] In one embodiment, the stem fitting 218 is supplied together with the trigger nipple 166. One or more of the stem fitting 218 and / or trigger nipple 166 can be supplied integrally with the base 102. In In use, stem socket 218 is seated inside chamber 192 of trigger nozzle 166. In another case, stem socket 218 and / or trigger nozzle 166 can be supplied separately, such as, for example, in conjunction with container 104 In an additional embodiment, the rod insert 218 can be omitted. In a different embodiment, another mechanism can be used to provide an interface between the valve stem 212 of the container 104 and the actuator nozzle 166.
[0110] Axial compression, that is, the downward movement, of valve stem 212 opens the valve assembly, which allows a pressure difference between an interior of the aerosol container 104 and the atmosphere to force the contents of the aerosol container 104 out through the distal end 216 of valve stem 212. It is also contemplated that the aerosol container 104 may use a tilt-activated valve stem with minimal modifications or no modifications to the structure described later. In any situation, a dosing valve set or a continuous valve set can be used. In addition, in other embodiments, a container 104 having a conventional pump-type sprayer or actuator type or a pump-type sprayer or pre-compression actuator type is used in place of an aerosol container 104 to hold and distribute the fluid medium. In fact, it is contemplated that any type of non-aerosol container can be used in conjunction with the dispensers described here. For example, other containers may include a different pump type sprayer, compressed gas, LPG, or any compressed or compressible fluid, as would be known to those skilled in the art. The present description with respect to aerosol containers should therefore be considered as inclusive of these other types of non-aerosol containers.
[0111] Container 104 includes a composition therein which is generally provided as a fluid medium, and more particularly as an aerosol composition. In one embodiment, the fluid medium is a pest control agent. In another embodiment, the fluid medium is a fragrance agent for air. In an additional embodiment, the fluid medium is an agent against bad odors.
[0112] The aerosol composition can be characterized by certain properties that improve the performance of the composition. More specifically, the aerosol composition must have one or more of the characteristics described here to ensure that the dispenser 100 can provide one or more visual indicators, described in greater detail below. With respect to the present embodiment, the aerosol composition provided is a stable, single-phase liquid non-aqueous composition that distributes at least one active ingredient contained therein to the air and / or to the sleeve 106.
[0113] The aerosol composition includes at least one hydrocarbon propellant, at least one active ingredient, and at least one solvent. The composition can include one or more optional components that are compatible with it.
[0114] In order to drive the fluid out of the distributor 100, a propellant can be included in the composition. The propellant can be any conventional propellant known in the art that is compatible with the solvent, active ingredient and other ingredients of the composition.
[0115] The propellant is generally present in an amount of about 20% by weight to about 99% by weight. More specifically, the propellant component is included in an amount of about 30 wt% to about 95 wt%, preferably about 70 wt% to about 90 wt%, and more preferably about 50 wt% weight at about 80% by weight. In one case, the propellant is present in an amount of about 80% by weight.
[0116] Suitable hydrocarbons for inclusion in the composition include lower aliphatic (C1-C4) hydrocarbons such as propane, butane, isopropane, isobutane, and mixtures thereof. A particularly suitable propellant is propellant B-52 which is a propane / isobutane / n-butane mixture in a weight ratio of about 30/30/40.
[0117] Other suitable propellants include, but are not limited to, hydrocarbons, halogenated hydrocarbons, ethers, carbon dioxide, compressed air, compressed nitrogen and the like. In a refinement, the propellant is a B-60 propellant, which is a mixture of propane, butane and isobutane. In another refinement, the propellant is an A-60 propellant, which is a mixture of propane and isobutane.
[0118] The composition additionally includes at least one active ingredient. The at least one active ingredient of the aerosol composition is present in an amount of about 0.001% by weight to about 10% by weight, preferably about 0.5% by weight to about 7% by weight, and more preferably about 1% by weight to about 5% by weight. One or more active ingredients can be used in combination in the aerosol composition. Active ingredients suitable for inclusion are known materials and / or suitable for spray delivery.
[0119] In one embodiment, the active ingredient is preferably an insecticide, an insect repellent, or an insect attractant. Alternatively, the active ingredient can be a disinfectant, sanitizer, air purifier, an aromatherapy oil, an air sanitizer, and / or deodorizer. Other examples of active ingredients include fragrances (for example, natural or synthetic oils), odor eliminators, such as triethylene glycol and / or propylene glycol, antimicrobials, antibacterials, corrosion inhibitors, pH adjusters, preservatives, organic acids and the like, or any other active ingredient that is usefully distributed into the air.
[0120] In one embodiment, the active material is an insecticide and / or insect repellent, an organic phosphorus insecticide, an insecticide and lipidamide, a natural repellent such as citronella oil, a natural pyrethrin, a pyrethrum extract, or synthetic pyrethroids. Suitable synthetic pyrethroids are acrinatrin, alethrin such as D-alethrin, Pynamin®, benflutrin, bifenthrin, bioalentrin such as Pynamin Forte®, S-bioalethrin, sbiotrin, esbiol, bisoresmethrin.cycloprotrin, cyfluthrin, beta-cyflothrin, cyhalothrin, cyhalothrin, cyhalothrin, cyhalothrin, cyhalothrin, cyhalothrin, cyhalothrine, , alpha-spermetrin, beta-cypermethrin, cyphenothrin, deltamethrin, empentrin, sphenoparrene, fenpropatrin, fenvalerate, flucitrinate, taufluvalinate, cadetrin, permethrin, phenothrin, pralethrin, tetrofretrine, teflutrin, teflutrin, teflutrin, teflutrin, treflutrin, teflutrina, combinations thereof. Other volatile insecticides. such as those described in U.S. Patent No. 4,439,415, can also be employed.
[0121] In particularly preferred versions, the volatile insecticide is selected from the group consisting of transflutrin, metoflutrin, vapotrin, permethrin, pralethrin, teflutrin, and sbiotrin. In a particular embodiment, metoflutrin is the most preferred insecticide.
[0122] A wide variety of volatile fragrances can be used and can also optionally have insect control attributes. Alternatively, some fragrances can be selected and provide a deodorant function (for example, certain terpenes). For example, several natural and artificial perfumes can be used. Non-limiting examples of such perfumes include animal and plant based perfumes, and artificial perfumes such as alcohols, phenols, aldehydes, ketones, terpenes, and esters.
[0123] The fragrance according to this description can comprise one or more aromatic materials or materials that provide chemically active vapors. In one embodiment, the fragrance may comprise and / or include volatile aromatic compounds including, but not limited to, natural botanical extracts, essences, aromatic oils and so on. As is known in the art, many essential oils and other derivatives of natural plants contain high percentages of highly volatile aromas. In this regard, numerous essential oils, essences and aromatic concentrates are commonly available from companies in the field of fragrances and foods.
[0124] Illustrative oils and extracts include, but are not limited to, derivatives of the following plants: almond, amyris, anise, armoise, bergamot, cabreuva, marigold, canaga, cedar, chamomile, coconut, eucalyptus, fennel, jasmine, juniper, lavender , lemon, lemongrass, orange, palm, mint, quassia, rosemary, thyme and so on.
[0125] In one embodiment, the composition can be carried in a solvent such as an organic solvent, and more particularly a hydrocarbon solvent. The solvent is present in an amount of about 1% by weight to about 30% by weight, preferably about 5% by weight to about 30% by weight, and more preferably in about 15% by weight to about 25% by weight. In a particular case, the solvent is present in an amount of about 10% by weight.
[0126] The types of solvent that are useful include, but are not limited to, Isopar C, Isopar E, Isopar L, heptane, methanol, acetone, ethanol, isopropyl alcohol, dodecene and tetrahydrofuran. ISOPAR® brand solvents are high purity isoparaffin fluids with narrow boiling ranges manufactured by ExxonMobil Chemical, where different grades are denoted E, G, L, M and V.
[0127] A composition particularly suitable for use in dispenser 100 comprises an aerosol composition having a propellant in an amount of about 80% by weight, a solvent in an amount of about 19% by weight, an active ingredient in an amount of about 1% by weight and a fragrance in an amount of less than 1% by weight. In another embodiment, the aerosol composition comprises the propellant in an amount of about 90% by weight, an active ingredient in an amount of about 1% by weight, and a solvent in an amount of 9% by weight. In an additional embodiment, the aerosol composition comprises the propellant in an amount of about 95% by weight, an active ingredient in an amount of about 1% by weight, and a solvent in an amount of about 4% by weight . In another embodiment, the aerosol composition comprises the propellant in an amount of about 85% by weight, an active ingredient in an amount of about 2% by weight, and a solvent in an amount of about 13% by weight.
[0128] A particularly desirable formulation for mosquito control includes 1% by weight of metoflutrin dissolved in 18.8% by weight of Isopar L hydrocarbon and additionally includes eucalyptus oil in an amount of 0.15% by weight and B propellant -52 in an amount of 80% by weight.
[0129] Numerous characteristics of the aerosol are important to achieve the specific dispensing capabilities of the dispenser 100 described here. For example, the particle size of the aerosol composition after dispersion as a jet is important. In one embodiment, the average particle size of the jet droplets is greater than or equal to about 5 microns. In another embodiment, the average particle size of the jet droplets is greater than or equal to about 10 microns. In an additional embodiment, the average particle size of the jet droplets is greater than or equal to about 15 microns. In another embodiment, the average particle size of the droplets is between about 5 microns and about 200 microns. More particularly, it has been found that a Dv (50) particle size distribution of 5 microns to 100 microns can preferably be, and a Dv (50) particle size distribution of 11 microns to 74 microns is even more possible. Additionally, it has been found that a Dv (90) particle size distribution of 5 microns to 200 microns may be preferable and a Dv (90) particle size distribution of 25 microns to 126 microns even more preferable. In another embodiment, the droplets can have a particle size distribution Dv (90) that is less than or equal to 30 microns.
[0130] Another important property of the aerosol composition is the jet rate during distribution. In particular, a sufficient aerosol composition must be discharged to provide the visual and audible indicators as described below, but too large a spray rate can result in the aerosol composition being discharged into and / or through the sleeve 106 in an undesirable manner. It is believed that an aerosol composition having a spray rate of more than 60 grams per second at an impact point with the sleeve 106 can result in undesirable spray characteristics, for example, the composition can be sprayed through a wall of the sleeve as opposed to being deposited on and subsequently absorbed by sleeve 106.
[0131] It is further believed that an aerosol composition having a jet rate of about 5 grams per second at a discharge point (that is, after leaving an exit port 190) would be insufficient to supply one or more of the indicators described here, for example, a trail within or above sleeve 106 and / or a wet area in the sleeve. Therefore, it is desirable that the jet rate of the aerosol composition is at least about 10 grams per second at the discharge point, but less than about 60 grams per second at an impact point with the sleeve 106, which has the physical properties noted below. In some specific embodiments, the aerosol composition is discharged from container 104 at a jet rate of at least 10, at least 20, or at least 30 grams per second, and less than about 70, about 60, or about 50 grams per second.
[0132] Another important parameter is the density of the composition. In particular, density impacts, among other things, the jet rate of the composition, which ultimately affects how much of the jet is retained within the sleeve 106 and how much of the jet is formed in a trail. It is envisaged that the density of the composition (measured at 15 ° C) is between about 0.2 g / cm3 to about 1 g / cm3. In one embodiment, the composition density (measured at 15 ° C) is between about 0.4 g / cm3 and about 0.8 g / cm3. In a different embodiment, the composition density (measured at 15 ° C) is between about 0.5 g / cm3 and about 0.7 g / cm3. In a different embodiment, the composition density (measured at 15 ° C) is about 0.6 g / cm3.
[0133] Turning now to figures 17 to 19, the dispenser 100 additionally includes the sleeve 106, which is supported on the base 102 through the recess 162 disposed between the guard 150 and the dome 152 (see figure 12). Sleeve 106 is defined by a permeable and / or absorbent substrate 230 having an inner surface 232 and an outer surface 234. In one embodiment, substrate 230 is folded to form an elongated conduit 236 (see figure 17) joined by an upper opening 238 and a lower opening 240 with a channel 242 extending between them. The substrate 230 has an upper end and a lower end corresponding to the upper opening 238 and the lower opening 240, respectively. The channel 242 and the upper opening 238 are unobstructed to allow the aerosol composition to exit directly through it (for example, without being prevented by a cap). In addition, the lower opening 240 is not obstructed to allow sleeve 106 to match dome 152. In a particular embodiment, the sleeve / conduit / substrate is positioned on or adjacent to the base (e.g. dome 152) in a way that encompasses or surrounds it. It is also anticipated that other embodiments may include a sleeve 106 with structures within the channel 242 and / or other parts to provide rigidity to the sleeve 106 or otherwise perform the spraying and distribution of the fluid medium. In addition, the sleeve 106 may be one or more among opaque, translucent or transparent.
[0134] In one embodiment, sleeve 106 can be provided as a tubular element, which can comprise any geometric shape. In another embodiment, the sleeve 106 can be printed with a circular or oval shape. In an additional embodiment, sleeve 106 may be provided in a square or rectangular shape. In a different embodiment, sleeve 106 is printed with a shape having a non-uniform cross section that includes at least one main geometric axis extending between the two points furthest from the shape and / or a smaller geometric axis extending between two points closest to the format. In fact, in other embodiments, the sleeve 106 may be provided with other formats including channel 242 providing an exit path from the base 102 into the external environment outside the sleeve 106.
[0135] In one embodiment, conduit 236 is provided with a transverse geometry substantially similar to that of base 102. In particular, substrate 230 has a uniform transverse footprint along its length and includes four distinct arched sides 244a-244d as viewed from a top plan view (see figure 18). The sides 244a-244d are joined at the corners 246a-246d to form the conduit 236. One or more of the sides 244a-244d can be integral with respect to each other, or the conduit 236 can be formed by joining one or more of the sides 244a-244d to each other in ways known in the art (for example, by an adhesive, an interlocking mechanism, stitching and other joining mechanisms). The corners 246a-246d are the points of intersection between the sides 244a-244d and can be formed naturally due to the geometric shape of the sleeve 106, or they can be defined by a joint or another point at which the angle of the side 244a changes.
[0136] Each side 244a-244d of substrate 230 is defined by a thickness dimension of between about 0.1 mm and about 3 mm. In another embodiment, substrate 230 is defined by a thickness dimension of between about 0.1 mm to about 0.17 mm. In an additional embodiment, substrate 230 is defined by a thickness of between about 0.17 mm to about 0.30 mm. In an additional embodiment, substrate 230 is defined by a thickness dimension of no more than about 2 mm. In another different embodiment, substrate 230 is defined by a thickness dimension of not less than about 0.1 mm. In a different embodiment, substrate 230 is defined by a thickness dimension of not less than about 0.08 mm and no more than about 2 mm. In an additional embodiment, substrate 230 is defined by a thickness dimension of between about 0.07 mm and about 0.8 mm. In a different embodiment, substrate 230 is defined by a thickness dimension of between about 0.13 mm and about 0.38 mm. In an additional embodiment, the thickness can be impacted due to the inclusion of a reinforcement element on one or more of the sides 244a-244d. For example, in one embodiment, nylon can be added to sides 244a-244d. In a particular embodiment, a scrim is added to a non-woven substrate to increase its stiffness. In a different embodiment, another material and / or an additional material can be added or otherwise applied to sides 244a-244d.
[0137] As shown in figure 19, each side 244a-244d of substrate 230 is defined by a height dimension Hs measured between an upper and lower edge of each side 244a-244d. In one embodiment, the height dimension Hs is between about 50 mm and about 300 mm. In another embodiment, the height dimension Hs is between about 100 mm and about 200 mm. In an additional embodiment, the height dimension Hs is between about 150 mm and about 200 mm. In an additional embodiment, the height dimension Hs is not more than about 300 mm. In a different embodiment, the height dimension Hs is not less than about 25 mm. In a different embodiment, the height dimension Hs is not less than about 250 mm and not more than about 400 mm. In another embodiment, the height of the sides 244a-244d may differ from each other.
[0138] The substrate 230 of the sleeve 106 can generally be characterized as having a horizontal component and a vertical wall extending upwardly from the horizontal component. Each side 244a-244d of substrate 230 is also defined by a horizontal length dimension Ls, as measured between the corners 246a-246d of the sleeve 106. For example, as shown in Figure 19, the horizontal length dimension Ls of side 244a is defined as the length of side 244a between corner 246a and corner 246d. In one embodiment, the horizontal length dimension Ls is between about 25 mm and about 200 mm. In another embodiment, the horizontal length dimension Ls is between about 40 mm and about 80 mm. In an additional embodiment, a horizontal length dimension Lt can be characterized as the total linear horizontal length component of the sleeve 106, where Lt can be between about 50 mm and about 1000 mm, and more preferably between 50 mm and about 200 mm. In another embodiment, the horizontal length dimension can vary from one or more of the sides 244a-244d to create the different geometric shapes.
[0139] In many cases, the height of each side 244a-244d of the sleeve 106 is related to numerous other properties of the dispenser 100. For example, the sleeve 106 is sized to accommodate specific spray angles, spray rates, compositions, and numerous other parameters described here. In a particular example, it is contemplated that the height dimension Hs on the sides 244a-244d of the sleeve 106 is related to the horizontal length dimension Ls or Lt. In one embodiment, the ratio of height Hs to the horizontal length dimension Ls of one side 244 of the dispenser 100 is about 3 to about 1. In another embodiment, the height ratio Hs to the horizontal length dimension Lt is between about 1 to about 1. In an additional embodiment, the height ratio Hs for horizontal length dimension Ls is greater than about 2 to about 1.
[0140] The volumetric capacity of conduit 236 or channel 242 is important to help facilitate the formation of one or more indicators, discussed in greater detail below. In particular, conduit 236 must have a volumetric capacity large enough to accommodate the jet of container 104 to form a trail and / or a wet area. If the volumetric capacity is too large, it is believed that the trail does not form properly and that insufficient spray material is deposited on the sleeve 104 in the manner described here to provide an effective passive diffusion. In contrast, if the volumetric capacity is very small, a significant amount of jet from the container 104 will come out of the sleeve 106 and will not be deposited therein and / or for passive diffusion. In addition, a lower volumetric capacity will deplete the aerosol composition material available to form the trail, which can result in deficiencies with respect to trail formation.
[0141] Therefore, conduit 236 or channel 242 can be supplied with a limited volumetric capacity of between about 100 cm3 to about 4000 cm3, when conduit 236 is standing and not arranged in base 102. In another embodiment, the conduit 236 is defined by a limited volumetric capacity of between 300 cm3 and about 800 cm3. In an additional embodiment, conduit 236 is defined by a limited volumetric capacity between 600 cm3 and about 650 cm3. In an additional embodiment, conduit 236 is defined by a limited volumetric capacity of no less than about 100 cm3. In a different embodiment, conduit 236 is defined by a limited volumetric capacity of no less than about 400 cm3. In another different modality, conduit 236 is defined by a limited volumetric capacity of no less than 600 cm3 and no more than about 4000 cm3. In a particular embodiment, conduit 236 is defined by a limited volumetric capacity of about 640 cm3. In a different modality, channel 242 of the conduit has an internal volume of between 300 cm3 and 400 cm3.
[0142] Channel 242 of substrate 230 or conduit 236 can be defined by several additional design and / or volumetric parameters of sleeve 106. In one embodiment, channel 242 is not interrupted. In this case, the inner surface 232 that defines the channel 242 is contiguous along its length and / or width and has no surface interruptions other than those exhibited by the individual fibers or constituent parts. For example, the inner surface 232 of channel 242 of Figure 20 is broken and the wall is substantially flat along its length. In another case, the continuous inner surface 232 of the channel 242 extends entirely between the upper opening 238 and the lower opening 240 of the sleeve 106. In a different embodiment, it is further contemplated that the continuous channel 242 can be completely limited so that the sleeve 106 is opaque. In an additional embodiment, both the inner surface 232 and the outer surface 234 are continuous.
[0143] In a different embodiment, channel 242 of substrate 230 is at least partially interrupted. In this mode, channel 242 can be interrupted through one or more mechanisms. For example, in one embodiment, at least one hole or other opening may be present in sleeve 106 (in addition to upper opening 238 and lower opening 240). In a specific embodiment, the surface interruption may comprise a substrate 230 having an average pore size greater than about 250 microns. In an additional embodiment, one or more parts of the substrate 230 may be provided as an interlacing and / or formed in a cross pattern to include a plurality of surface interruptions. In a further embodiment, one or more parts of the partially interrupted substrate 230 comprise a structure that divides the interior of the sleeve 106 into two or more separate volumes.
[0144] In some cases, surface interruptions may impact the formation of the trail and / or the amount of fluid material that extends through the sleeve 106 X the amount of fluid material that remains or is absorbed in the sleeve 106. In one embodiment differently, one or more parts of the substrate 230 may be provided with a notch, cutout, and / or other surface interruption in addition to the upper and lower openings 238, 240.
[0145] In an additional mode, channel 242 can be defined by the contour defined by its natural limit. For example, channel 242 can be printed with a specific geometric shape due to its structural and / or stiffness components. In one embodiment, channel 242 acts at least partially to limit the movement of the volatile or open air element.
[0146] Additionally, conduit 236 or channel 242 may have a limited volumetric capacity of between about 200 cm3 and about 700 cm3, when conduit 236 is arranged in base 102. In another embodiment, conduit 236 is defined by a limited volumetric capacity of between 300 cm3 and about 600 cm3. In an additional embodiment, conduit 236 is defined by a volumetric capacity limited to between 400 cm3 and about 550 cm3. In an additional embodiment, conduit 236 is defined by a limited volumetric capacity of no less than about 500 cm3. In a different embodiment, conduit 236 is defined by a limited volumetric capacity of no less than about 400 cm3. In a different embodiment, conduit 236 is defined by a limited volumetric capacity of no less than 300 cm3 and no more than about 600 cm3. In a particular embodiment, conduit 236 is defined by a limited volumetric capacity of about 515 cm3.
[0147] Conduit 236 may also include a minimum cross-sectional area within the limited volume of at least about 15 cm2 and a maximum cross-sectional area within the limited volume of less than about 400 cm2. In another embodiment, conduit 236 includes a minimum cross-sectional area within the limited volume of at least about 40 cm2 and a maximum cross-sectional area within the limited volume of less than about 100 cm2. In an additional embodiment, conduit 236 also includes a minimum cross-sectional area within the limited volume of at least about 38 cm2. It is contemplated that the maximum cross-sectional area may be provided at an upper end or outlet end of the conduit or substrate, or alternatively, the minimum cross-sectional area may be provided at the upper end. In fact, it is also contemplated that a globular shade or substrate can be provided with a maximum cross-sectional area around the medial part.
[0148] The conduit 236 can include a central geometric axis and, in some modalities, a smaller geometric axis, which can be perpendicular to it. In one embodiment, the minor geometric axis is a width of the sleeve 106. In an additional embodiment, the minor geometric axis comprises a line extending between the internal surfaces of two opposite walls. In an additional embodiment, the minor geometric axis can be a straight line measurement between two distal surfaces. In another embodiment, the smaller geometric axis can be a diameter.
[0149] The selection of material comprising sleeve 106 is important for a number of reasons. In particular, the material of the sleeve 106 impacts, among other things, the appearance of the sleeve 106, the absorption properties of the sleeve 106, the absorption properties of the sleeve 106, the ability of the sleeve 106 to be retained in a straight position at the base 102, the formation of a trail, and numerous other properties related to the display of one or more visual indicators.
[0150] Accordingly, the sleeve 106 may comprise a permeable material, such as a non-woven PET material, fabric, textile, non-woven fibers, or other permeable material. In a specific example, the sleeve material comprises a nylon fabric supplied by Cerex® Advanced Fabrics (Cantonment, Florida). In one embodiment, the fabric can be nonwoven, which is made by wrapping and autogenous joining of continuous nylon filaments into a smooth, strong and flat fabric. A particular suitable fabric is a nylon substrate sold under the trademark Cerex 23200. In a different embodiment, sleeve 106 can be woven and / or continuous. For example, sleeve 106 may be a smooth sheet having micropores (for example, Gore Tex® or a material similar to Gore Tex®). In a further embodiment, the sleeve 106 may comprise a laminate or other surface having an internal nylon surface.
[0151] In one embodiment, sleeve 106 is provided as a non-woven material that has between about 5 mils and about 12 mils, and more particularly between about 7 mils and about 9 mils as determined using ASTM- D1777. In one embodiment, the air permeability of the sleeve material 106 is between about 15 CFM / ft2 and about 325 CFM / ft2, and more particularly about 170 CFM / ft2, as determined by ASTM D737. The sleeve material 106 may also have a burst intensity of between about 2 bar and about 70 bar, and more particularly about 5 bar.
[0152] One or more material properties of sleeve 106 impact the distribution capabilities of dispenser 100. A preferred sleeve 106 is rigid and self-supporting so that it can remain in a straight position without assistance (for example, standing on end without structural disassembly). At the same time, sleeve 106 must be flexible enough to accommodate the recess 162 of base 102. In some cases, depending on the shape of sleeve 106, sleeve 106 may need to be flexible enough to bend or otherwise deform when sleeve 106 is being positioned on base 102. Sleeve 106 must also have moderate wetting characteristics and moderate porosity which results in an effective release profile compared to other materials. It may also be desirable that the sleeve 106 has properties of low affinity and absorption with respect to the active properties, in comparison with other materials.
[0153] The sleeve material can be characterized by one or more properties such as surface energy. Surface energy describes the excessive energy on the surfaces compared to the material in the volume. It is generally energetically preferable that the composition is in the bulk material rather than the surface of the sleeve 106. The surface energy provides a measure of the energy required to form the surface area and controls the amount of surface that will be formed, and, thus, the amount of surface that the liquid will have available for evaporation to occur. For this purpose, the material of the sleeve 106 preferably has a surface energy of less than about 25 mN / m. In another embodiment, the material has a surface energy of less than about 20 mN / m. In an additional embodiment, the material has a surface energy of less than about 18 mN / m. In a different embodiment, the material has a surface energy of between about 1 mN / m to about 30 mN / m. In another embodiment, the material has a surface energy of between about 5 mN / m to about 25 mN / m. In an additional embodiment, the material has a surface energy of between about 10 mN / m to about 20 mN / m. In a specific embodiment, the material has a surface energy of about 10 mN / m.
[0154] The visual appearance of the material used for the sleeve 106 is an additional important property to realize the functionality of the sleeve 106 described here. In particular, without being limited to theory, it is believed that a consumer experience is highlighted during the use of a distributor when the consumer can perceive that a distributor is working and that the distributor has the characteristics to provide adequate functionality. For example, consumers recognize that a solid plastic surface or another impermeable-looking surface is generally unable to provide passive emanation due to a lack of absorption. In particular, consumers understand that the sprayed composition can accumulate and not be absorbed on the surface. In addition, some consumers realize that continuous and / or smooth-looking surfaces may not have adequate absorbent properties regardless of the true nature of the material, and will not be confident that the material will absorb the composition or passively diffuse it. In contrast, consumers understand that fabric or textile materials provide a specific visual appearance and that the materials can absorb the aerosol composition, and are thus capable of providing passive emanation. Therefore, it is desirable to provide a sleeve 106 having specific properties that assist the consumer in recognizing the absorbent nature. Sleeve 106 must be provided with one or more of the following parameters to ensure that sleeve 106 provides a sufficient visual indicator of absorption.
[0155] The sleeve material 106 is preferably defined by a plurality of fibers having a diameter greater than about 50 microns. In one embodiment, the fiber diameter is between about 45 microns and about 120 microns. In another embodiment, the diameter of the fibers is between about 50 microns and about 100 microns. In a different embodiment, the diameter of the fibers is between about 60 microns and about 90 microns. In an additional embodiment, fiber diameters are between about 70 microns and about 80 microns. In a specific embodiment, the diameter of the fibers is about 90 microns. In another embodiment, the diameter of the fibers is about 100 microns. In an additional embodiment, the fiber diameters are about 120 microns. In another embodiment, the diameter of the fibers is about 130 microns.
[0156] The coloring of the fibers in the material of the sleeve 106 is also important to provide a visual indicator for the user of the fabric-like nature of them. In particular, the coloring of the fibers of the sleeve 106 provides contrast that assists the user in the visual perception of individual fibers. For example, in one case, the fibers of the sleeve 106 are the same color, such as white. In another case, one or more fibers can be printed with different coloring to provide a visual contrast between them.
[0157] The pore size is also important when printing a visual indicator specific to the user. In particular, the larger the pore size of the material, the more visible the pores are, which results in a consumer understanding that the sleeve material comprises a woven or otherwise absorbent material. The pore size between the fibers must be large enough to be visible and provide the impression of a porous material. For the texture of the sleeve material 106 to be visible, there must be sufficient contrast between the fibers and the pores. In particular, in one embodiment, the median pore diameter per volume may be at least about 50 microns or more, comprising individual pores or clusters of nearby pores. In another embodiment, the median pore diameter per volume of sleeve 106 is between about 50 microns and about 1000 microns. In another embodiment, the median pore diameter per volume of sleeve 106 is between about 50 microns and about 80 microns. In one embodiment, the median pore diameter per volume is between about 50 microns and about 250 microns. In another embodiment, the median pore diameter per volume is between about 50 microns and about 100 microns. In a specific embodiment, the median pore diameter per volume is at least 50 microns. In another embodiment, the median pore diameter per volume is about 60 microns. In an additional embodiment, the median pore diameter per volume is 75 microns. In another embodiment, the median pore diameter per volume is about 80 microns. In a different embodiment, the median pore diameter per volume is less than 80 microns. In an additional embodiment, the median pore diameter may not be consistent across the entire sleeve 106. For example, a portion of the sleeve 106 may be characterized by a median pore diameter of a first value (for example, about 50 microns ), while another part of the sleeve 106 can be characterized by a different second value (for example, about 70 microns).
[0158] The substrate 230 of the sleeve 106 can additionally be characterized by an empty volume (i.e., porosity) of at least 1.55 ml / g. In another embodiment, the substrate 230 of the sleeve 106 can additionally be characterized by a porosity of between about 1 ml / g to about 10 ml / g. In a further embodiment, the substrate 230 of the sleeve 106 can additionally be characterized by a porosity of between about 1.55 ml / g to about 7.13 ml / g. In a further embodiment, the substrate 230 of the sleeve 106 can additionally be characterized by a porosity of no more than about 8 ml / g.
[0159] The thickness of the sleeve material 106 is also important in providing the benefits realized through the use of the sleeve 106. For example, the sleeve 106 must be able to accommodate the jet speed of the fluid medium discharged from the trigger nozzle 166 and has sufficiently thick to prevent most of the jet from exiting directly through the sleeve 106. The thickness of the sleeve 106 is also important for the absorption and absorption properties. which impacts the formation of one or more of the visual indicators (for example, a trail and / or a wet area).
[0160] An additional consideration for the material of the sleeve 106 is the tactile feedback that the user can obtain from interaction with (for example, touching) the sleeve 106. The tactile feedback depends on numerous material characteristics including surface roughness, material "stiffness", and thermal behavior. A very smooth surface, such as a plastic film, should be impermeable to a liquid based on the user's experience with plastic sheets, whereas a more textured surface would be expected to allow the liquids to be absorbed based on the users' experience with fabrics.
[0161] The material of the sleeve 106 can also have absorption properties characterized by the average absorption speed, which impacts time to form the wet area in the sleeve 106 after activation. The average rate of absorption can be determined using gravimetric analysis. In one embodiment, the average absorption speed is between about 0.01 mm / s and 1.5 mm / s. In another embodiment, the average absorption speed is between about 0.05 mm / s and 1 mm / s. In a different embodiment, the average absorption speed is between about 0.07 mm / s and about 0.09 mm / s. In one embodiment, the average absorption speed is between about 0.05 mm / s and about 0.1 mm / s. In a specific modality, the average absorption speed is about 0.09 mm / s. In another mode, the average absorption speed is about 1 mm / s. In an additional embodiment, the average absorption speed is about 0.095 mm / s. In another additional embodiment, the average absorption speed is at least about 0.05 mm / s. In another embodiment, the average absorption speed is at least about 0.05 m / s.
[0162] The volume density of the sleeve 106 also impacts the rigidity and feel properties of the substrate 230 of the sleeve 106. In one embodiment, the volume density is between about 1 g / cm3 and about 2 g / cm3. In another embodiment, the volume density is less than about 1.275 g / cm3. In an additional embodiment, the volume density is between about 1.142 g / cm3 and about 1.273 g / cm3. In a different embodiment, the volume density is less than about 2 g / cm3. In an additional embodiment, the volume density is between about 1 g / cm3 and about 3 g / cm3.
[0163] The resistance to strip tension of sleeve 106 is related to the stress that substrate 230 can handle before failing. In one embodiment, the resistance to strip tension is at least about 3 N / mm, and more specifically about 3.03 N / mm. In another embodiment, the resistance to strip tension is at least about 4 N / mm. In an additional embodiment, the resistance to strip tension is between about 2.5 N / mm and about 3.5 N / mm.
[0164] The material of the sleeve 106 additionally includes absorption properties characterized by the absorption capacity, as measured by gravimetric analysis. In one embodiment, the absorption capacity is from about 1 ml / g to about 3.5 ml / g. In another embodiment, the absorption capacity is from about 1.5 ml / g to about 3 ml / g. In a different embodiment, the absorption capacity is from about 2 ml / g to about 3 ml / g. In a specific embodiment, the absorption capacity is about 2.5 ml / g. In another embodiment, the absorption capacity is about 2.6 ml / g. In an additional embodiment, the absorption capacity is about 2.7 ml / g. In another embodiment, the absorption capacity is at least about 2.5 ml / g. The sleeve material 106 is also capable of absorbing about 0.015 mg / mm2 of the fluid medium.
[0165] A particular sleeve 106 having the following characteristics is useful with respect to the dispenser 100 described here. Sleeve material 106 has a nominal sheet thickness of 8.4 mils or 0.21 mm and is composed of a multiplicity of non-woven fibers, interspersed with pores having a median pore diameter (by volume) of about 50 microns . In this modality, the material has a porosity of 1.55 ml / g. The gravimetric derived density is 0.4 mg / mm3 and the volume density is 1.14 g / cm3. Additionally, sleeve 106 is defined by a resistance to strip tension in the cross direction of about 3N / mm and a resistance to strip tension in the machine direction of about 5.6 N / mm.
[0166] Referring again to figures 1 to 3, sleeve 106 is shown to be printed with a pattern 250 formed thereon. Pattern 250 can be constructed from the absorbent material and / or a portion 252 of substrate 230 surrounding the pattern can be constructed from the same or another material. The pattern 250 can also be formed by openings through the substrate 230 in the shape of the pattern 250. In this case, the absorbent material can partially or completely cover the openings. In some cases, the pattern is defined by one or more natural-looking objects such as leaves, flowers, plants, trees and the like. In other modalities, the standard can be defined by other formats.
[0167] The parts of the component having been described, the use of the distributor 100 and the properties related to it are now discussed in more detail. One or more components of the dispenser 100 can be supplied in the packaging (not shown). For example, an initial package may include base 102, one or more containers 104, and sleeve 106. In one embodiment, container 104 and / or sleeve 106 is provided as a refill kit.
[0168] In a different mode, the sleeve can be preloaded with the fluid substance. In this embodiment, it is contemplated that the fluid substance would be supplied in a non-permeable package and that the fluid medium would not begin to passively diffuse until the sleeve 106 is removed from the package. In a further embodiment, a sleeve 106 with the fluid medium pre-loaded therein can be used in combination with a fluid medium disposed within the container 104. For example, it is contemplated that a substance (for example, the active ingredient) can be pre-loaded in sleeve 106 and a second substance (for example, the solvent) would be supplied in container 104. In that case, the solvent would come in contact with the active ingredient during activation to supply a synergistic effect. Alternatively, the preloaded fluid medium in sleeve 106 can become active and initiate passive diffusion only by interacting with a second fluid medium supplied in container 104, or otherwise sprayed in dispenser 100. Additionally, an active ingredient can be disposed in container 104, while a different second active ingredient (and / or fluid medium) is preloaded in sleeve 106. For example, a pest control agent or active ingredient can be supplied in container 104, whereas a fragrance can be pre-loaded on sleeve 106.
[0169] To use dispenser 100, each component part must be removed from the package, and container 104 having an aerosol composition must be inserted into base 102. To insert container 104 into base 102, the upper housing 110 must be removed from the lower housing 108 of the base 102 (if the components are joined). To remove the upper housing 110 from the lower housing 108, a user can grasp the grooves 116 of the lower housing 108 with one hand and use the other hand to apply an upward force to the upper housing 110 in a direction away from the lower housing 108. One Once the lower housing 108 is exposed, the user positions the container 104 in the opening 136 of the pedestal 134 to be retained at least.
[0170] Once the container 104 is properly positioned, the base 102 must be reassembled. To secure the upper housing 110 to the lower housing 108, each is substantially aligned with the other. The upper housing 110 is lowered into the lower housing 108, which causes the angled end portions 178 of the protrusions 170 to come into contact with the tapered horizontal sections 130 of the flanges 126 of the U-shaped elements 124. The U-shaped elements 124 flex inward to allow protrusions 170 to slide inward and be retained in openings 128 of elements 124. Once protuberances 170 are seated within openings 128, U-shaped elements 124 flex outward to their original position to releasably lock the upper housing 110 to the lower housing 108 (see figure 11). At the same time, the container 104 is oriented upwardly through the upper housing 110 through ribs 174 until the valve stem 212 of the container 104 is positioned fairly within the stem fitting 218.
[0171] If the sleeve 106 is not pre-assembled in the distributor 100, the sleeve 106 is positioned on the base 102 by aligning the sleeve 106 over the dome 152 and the lowering of the sleeve 106 downwardly thereto. The dome 152 is received in the lower opening 240 of the sleeve 106. As the sleeve 106 moves downwards towards the dome 152, the sleeve 106 interacts with the recess 162 disposed between the guard 150 and the dome 152. Once positioned, the sleeve 106 contacts the side walls 158 of the dome 152 through at least a part of it. The sleeve 106 can be supplied in a shape similar to that of the dome 152 to facilitate a uniform appearance to the dispenser 100. Additionally, the sleeve 106 can be supplied in a different shape, provided that the sleeve 106 can be inserted into the recess 162, while, at the same time, it has sufficient rigidity properties consistent with the spraying mechanisms described here.
[0172] In the presented modality, the base 102 of the distributor 100 is printed with a specific format that provides a visual tip for the user during the configuration. In particular, sleeve 106 includes a shape similar to that of base 102, and in particular that of recess 162 disposed between protection 150 and cupola 152. This orientation helps to ensure the proper orientation of the dispenser and prevents the use of sleeves 106 that may not be suitable for distributor 100 or cause distributor 100 to function improperly.
[0173] After the distributor 100 components are assembled, the distributor 100 is in a resting state where an upper end of the dome 152, that is, the actuator nozzle 166 and the stem fitting 218, is in physical communication with the distal end of the container 104 (for example, the distal end 216 of the valve stem 212) and the protrusions 170 are positioned within the openings 128 of the elements 124. As shown in figures 1 and 2, in the resting state, the lower edge of the lower housing 108 extends from the opening 168 and is maintained adjacent to a support surface (not shown). The container 104 is prevented from carrying out the additional internal movement inside the base 102 through the interaction of the valve stem 212 exerting a force against the actuator nozzle 166, which by itself interacts with the raised circular surface 181 in the dome 152. Thus, the weight of the upper housing 110 rests on the actuator nozzle 166, and a spring (not shown) contained within a valve assembly (not illustrated) supports the upper housing 110 above the lower housing 108.
[0174] The effort of a downward force component in the upper housing 110 (for example, protection 150 or dome 152) causes it to move axially downward, that is, in a direction parallel to a longitudinal geometric axis C (see figure 2) with respect to the upper housing 110, thus causing the compression of the valve stem 212 and the resulting release of the contents of the aerosol container 104. Although any part of the upper housing 110 can be axially pressed, it is contemplated that it may be more convenient for the user to grab the guard 150 during activation due to the fact that the sleeve 106 is arranged in the dome 152, which could obstruct the user's hand during the activation.
[0175] After manual override, the upper housing 110 returns to its original position after releasing the downward force by means of the spring disposed within the valve assembly of the container 104. Additional means to support the weight of the housing and return it to the pre-operational position are also glimpsed in a manner known in the art.
[0176] An advantage of activating the dispenser 100 in the present mode is that a user can release the composition from the container 104 while minimizing the direct exposure to the composition, since the user does not need to put his hand on the trigger nozzle 166. Additionally, the combination of the relatively high sleeve 106 additionally minimizes direct exposure to a user after the composition has been released by directing the composition at least partially vertically in addition to restricting the amount of composition emitted directly into the immediate environment.
[0177] During actuation, the aerosol composition is released from the container 104 and exits the valve stem 212 at the distal end 216. The aerosol composition is released into the chamber 192 of the trigger nozzle 166 and is distributed from there through output parts 190a-190d. As illustrated in figure 20, when the aerosol composition exits the outlet ports 190a-190d, the aerosol composition disperses in one or more streams 300 that may have a spray pattern that results, for example, in primary vectors 302, secondary 304 and tertiary 306 due to deviations from the inner surface 232 of the sleeve 106. In fact, any number of deviations can occur.
[0178] Chain 300 is divided according to the number of output ports 190 present in the trigger nozzle 166. In the mode illustrated in figure 21, four chains 300a, 300b, 300c, 300d are supplied from output ports 190a 190d, respectively. Chains 300a-300d are generally directed to internal surfaces 232 on each side 244a-244d. In particular, currents 300a-300d leave the trigger nozzle 166 at a specific contact angle that balances the amount of composition that must be provided on the inner walls 232, and the amount of composition that must be released in the trail.
[0179] The contact angle (for example, incidence angle) between the active ingredient present in currents 300a-300d and the sleeve material, in part, determines its wetting capacity. The contact angle also controls the spread of the active ingredient and the size of the wetted area for a given amount of active ingredient. For a small contact angle (for example, less than about 30 degrees), the liquid will have a relatively small spread across the sleeve material and will likely enter directly or through a sleeve wall if comprised of an absorbent material, while that the liquid will remain in a more spherical shape and thereby accumulate and / or exit sleeve 106 directly at a greater contact angle (for example, greater than about 70 degrees). The contact angle is preferably measured with respect to a longitudinal geometric axis of one or more of a container, substrate, base or conduit. For example, in the present embodiment, the contact angle can be measured with respect to the geometric axis C of the conduit.
[0180] Therefore, the contact angle between currents 300a-300d and sleeve 106 can be provided between about 30 degrees and about 80 degrees or about 30 degrees and about 70 degrees. In other embodiments, the contact angle is at least about 40 degrees. In different embodiments, the angle of contact is between about 45 degrees and 85 degrees. In an additional embodiment, the contact angle is between about 50 degrees and about 90 degrees. In an additional embodiment, the contact angle is between 55 degrees and about 66 degrees. In a specific embodiment, the contact angle is about 30 degrees. In another embodiment, the contact angle is about 40 degrees. In a different mode, the contact angle is about 50 degrees. In an additional embodiment, the contact angle is about 60 degrees. In another additional embodiment, the contact angle is about 60 degrees. In an additional embodiment, the contact angle is not less than about 30 degrees and not more than about 80 degrees.
[0181] After actuation, one or more currents 300a-300d of fluid travel out of the actuator nozzle 166 and into channel 242 defining the sleeve 106, as described in detail below. The streams of the composition distributed from the trigger nozzle 166 provide different functionality according to various properties of the distributor. For example, it is contemplated that one or more currents can pass directly through the sleeve 106 into the external environment to provide immediate active diffusion. In one embodiment, the amount of composition that passes directly through the sleeve wall 106 is minimized so that most of the composition will be retained within the sleeve 106 (for example, on or within the inner wall 232 of the sleeve 106 or on the trail ). In another embodiment, the amount of composition passing directly through the sleeve wall 106 can be increased to provide a larger initial burst of composition.
[0182] One or more chains also come into contact with the inner surface 232 of the sleeve 106 and are at least partially absorbed by the same. The currents in contact with the inner surface 232 form a wet spot, where the composition absorbed in the sleeve 106 is partially actively emitted, but most of the absorbed composition is passively emitted for a period of time after the initial activation.
[0183] Additionally, one or more chains can also form a trail, where at least part of the trail is retained with the sleeve 106 and at least part of the trail runs out through the upper opening 238 of the sleeve 106. In other embodiments, the trail can be characterized as exiting sleeve 106 through an outlet or an outlet opening / orifice, outlet opening / orifice, an upper end, an outlet opening, etc. of the sleeve, conduit or substrate. The trail also provides an initial active burst after manual activation and continues to emanate actively for a short period of time after its formation.
[0184] More particularly and with specific reference to figure 22, after the release, a first quantity 308a-308d of chains 300a-300d formed of small particles of aerosol composition can exit through the sleeve 106 directly through the sides 244a-244d to create an immediate effect on the surrounding environment. In this embodiment, the significant amount of the composition that travels directly through the sleeve 106 provides a greater burst (e.g., active ingredient) of composition compared to other modalities and may be desirable for certain applications.
[0185] As illustrated in figures 21 and 22, a second quantity 310a-310d of chains 300a-300d is deposited on the inner surfaces 232 of the sleeve 106 on each side 244a-244d and may permeate through the sleeve 106 immediately and / or with time. When the chains 300a-300d come into contact with the sleeve 106, the material of the sleeve 106 is wet and provides a visual contrast to the dry parts of the sleeve 106. After spraying, one or more points 310 (illustrated individually as 310a, 310b , 310c, and 310d) are provided on one or more of the sides 244a-244d that comprise the wetted area.
[0186] As shown in figure 23, a first quantity 312 of chains 300a-300d is created by deflecting the chains 300a-300d from the inner surface 232. The parts of the chains 300a-300d combine to form a trail 314 having a component internal 314a and an external component 314b. In particular, a portion of the trail 314a remains within the sleeve 106 and a portion of the trail 314b exits through the upper opening 238.
[0187] In this way, dispenser 100 creates multiple amounts of aerosol composition with different emanation rates due to interaction with sleeve 106. After manual activation of the dispenser, one or more of the amounts of current 308a-308d, 310a-310d , 312a-312d can provide both active and passive distribution.
[0188] It is contemplated that the selection of numerous distributor parameters 100 is important for realizing the advantages discussed here. In particular, some important factors are those that impact the formation of points 310a-310d and the passive emanation created, and the formation of the trail 314 and the active emanation generated. In addition, the properties of the composition before and during activation are also important.
[0189] First, with respect to the formation of the 310 points, a visible presence of a wet area in the sleeve 106 indicates to the user that the active ingredient is present in the sleeve 106 and will, after that, be released. The wet area is created as a result of contacting the carrier solvent with the sleeve 106 instead of the active ingredient. In some cases, it is also contemplated that the size of the wetted area can correlate with, and provide an idea of the amount of fluid medium distributed. For example, two drives from the distributor 100 can provide a larger wet area than a single drive.
[0190] To provide a visible change to sleeve 106, a number of mechanisms are useful. For example, in one case, the composition fills the empty spaces in the porous material of the sleeve 106. In that case, the sleeve material 106 must include empty spaces, the fraction of the empty space must be large enough to receive the composition, and the amount of composition deposited in the material must be sufficient to fill the empty spaces. In another case, the composition increases the opacity of the sleeve. In that case, the composition absorbs light so that the color of the sleeve 106 changes in contact with the composition. In this case, the composition selectively absorbs a selection of visible spectra.
[0191] For the wet area to be visible within a suitable time frame, it needs to be formed quickly. The formation time depends on the absorption properties of the sleeve material 106. An important component is the presence of interconnecting pores in the sleeve material 106 to provide an open structure.
[0192] The size of the wetted area also depends on the area in which the composition is deposited, which is a function of the cone angle of the trigger nozzle 166 and the spreading of the deposited composition across the surface. The surface scattering is a function of the surface energy, and the amount deposited (for example, the fraction of the composition dose of a single drive that is deposited x distributed in the trail). It may be desirable to customize the distributor's properties to ensure that the size of the wet area correlates with the deposited volume to demonstrate that multiple drives deposit more formulation.
[0193] The time of formation of the visible wet area depends on the absorption speed of the sleeve material 106. The dispersion of the visible wet area is related to the situation in which the wet area becomes too thin to be visible, which is the result spreading the composition excessively across the surface of the sleeve 106, and / or due to evaporation, remove sufficient liquid so that the composition layer is too thin to be visible.
[0194] It is contemplated that taking all this into consideration, the points 310 present in the sleeve 106 after activation can be characterized by the following parameters.
[0195] Points 310 appear on sleeve 106 in an approximately elliptical shape using the trigger (conical-shaped) nozzle 166 described here. The maximum height dimension and width dimensions of points 310 provide an absorption area in sleeve 106. Points 310 each include a maximum height dimension of about 30 mm to about 40 mm, and more particularly between about 32 mm and about 38 mm. In a specific embodiment, the maximum height dimension for each of the 310 points is about 35 mm. In addition, each of the points 310 includes a maximum width dimension of between about 20 mm and about 30 mm, and more particularly between about 22 mm and about 28 mm. In a specific embodiment, the maximum width dimension for each of the 310 points is about 25 mm.
[0196] In some embodiments, the maximum height dimension of each of the points 310 is characterized as a function of the height of the sleeve 106. For example, using a sleeve 106 having a height dimension of about 170 mm, the maximum height of each of the points 310 is approximately 1/5 of the height of the sleeve 106.
[0197] Points 310 are additionally defined by an average area parameter as determined after a selected period of time. In particular, points 310 have an area of about 2 cm2 to about 14 cm2, and more particularly between about 6 cm2 and about 10 cm2, after 10 seconds. In a specific embodiment, points 310 are characterized as having an area of about 8 cm2 after 10 seconds.
[0198] It is also seen that the absorption and diffusion properties of point 310 can be defined according to the time it takes for point 310 to develop visually more prominently after activation. In particular, points 310 are more prominent after a period of time from about 100 seconds to about 140 seconds, and more particularly from about 105 seconds to about 135 seconds. In a specific embodiment, points 310 are more prominent after a period of time of about 120 seconds.
[0199] Points 310 can also be characterized by their respective absorption and diffusion properties over the length of time the point is visible in sleeve 106. More particularly, points 310 are visible for a discrete amount of time after activation . In particular, in one embodiment, at least some of the points 310 are visible from a moment between 0.1 seconds after triggering and about 420 seconds after triggering. In another embodiment, points 310 are each visible from a moment between 0.1 seconds after activation and about 360 seconds after activation. In an additional modality, points 310 are each visible from a moment between 0.1 seconds after activation and about 300 seconds after activation.
[0200] The maximum absorption capacity of the sleeve 106 impacts the formation of the 310 point and can be determined by measuring the change in the mass of the sleeve when the sleeve is fully immersed in the solvent. The change in mass of the mango sample can then be used to calculate the maximum solution absorbed per material surface area (that is, the maximum absorption capacity). It is contemplated that one embodiment of sleeve 106 is defined by a sample area of about 408 mm2, and absorbs about 58 mg of solvent, which results in a mass of solvent absorbed per surface area of about 0.14 mg / mm2. In another embodiment, sleeve 106 is defined by a sample area of about 418 mm2 and absorbs about 55 mg of solvent, which results in a mass of solvent absorbed per surface area of about 0.13 mg / mm2. In an additional embodiment, sleeve 106 is defined by a sample area of about 425 mm2, and absorbs about 72 mg of solvent, which results in a mass of solvent absorbed per surface area of about 0.17 mg / mm2.
[0201] Therefore, in addition to other parameters discussed here, a sleeve material having the following properties is useful in conjunction with the distributor 100 described here. The sleeve material preferably has the ability to absorb the solvent per surface area of at least about 0.1 mg / mm2. In another embodiment, the sleeve material has the ability to absorb solvent per surface area of at least about 0.12 mg / mm2. In another embodiment, the sleeve material has the ability to absorb solvent per surface area of at least about 0.13 mg / mm2. In an additional embodiment, the sleeve material preferably has the ability to absorb solvent per surface area of at least about 0.14 mg / mm2. In addition, too much absorption of the solvent in the sleeve 106 can result in a less than desired or necessary trail to be efficient in generating a visual indicator. In one embodiment, the sleeve material preferably does not absorb solvent per surface area in an amount greater than about 0.2 mg / mm2.
[0202] The sleeve material 106 can also be characterized according to one or more absorption properties associated therewith. In particular, an embodiment of the sleeve 106 has an absorption height of about 100 mm, a surface area of about 3122 mm2, an amount of absorbed solvent of about 201 mg, a time to complete absorption of about 18 seconds, a mass of the formula absorbed per surface area of about 0.065 mg / mm2, and an absorption rate of about 0.09 mm / s. In another embodiment, sleeve 106 has an absorption height of about 101 mm, a surface area of about 2939 mm2, an amount of absorbed solvent of about 192 mg, a time to complete absorption of about 14 seconds , a mass of formula absorbed per surface area of about 0.065 mg / mm2, and an absorption rate of about 0.1 mm / s. In an additional embodiment, sleeve 106 has an absorption height of about 101 mm, a surface area of about 3073 mm2, an amount of absorbed solvent of about 166 mg, a time to complete absorption of about 20 seconds, a mass of formula absorbed per surface area of about 0.05 mg / mm2, and an absorption rate of about 0.08 mm / s.
[0203] Therefore, a sleeve material having the following properties is useful in conjunction with the dispenser 100 described here. The sleeve material has an absorption rate of at least about 0.06 mm / s. In another embodiment, the sleeve material has an absorption rate of at least 0.07 mm / s. In an additional embodiment, the sleeve material has an absorption rate of at least about 0.08 mm / s. In another embodiment, the sleeve material has an absorption rate of at least 0.09 mm / s. In a specific embodiment, the sleeve material has an absorption speed between about 0.06 mm / s and about 0.1 mm / s
[0204] A variety of factors impact the formation and dispersion of the trail 314. Therefore, numerous parameters are important to provide a trail that is visible above the sleeve 106 immediately after activation. One factor that must be considered is the volume of formulation dispersed in the trail, which is a function of the amount of formulation distributed and the relative proportion deposited in the sleeve 106 x distributed as droplets in the air, which, in turn, is related to the speed of the jet that leaves the trigger nozzle 166. Another factor that must be considered is the density of the trail of the droplets. The jet density is a function of the distribution of the aerosolized droplets of the trigger nozzle 166, the dispersion of the aerosol composition over time, and the evaporation rate of the droplets that create the aerosol composition.
[0205] An additional factor to be considered is the longevity of the droplet trail. The longevity of the trail is a function of the dispersion of the aerosol composition over time and the evaporation rate of the droplets that create the aerosol composition, in addition to the droplet size distribution, which results in how quickly the droplets sink under the action of gravity. The specific location is related to the distance traveled by the trail and the concentration effect of the trail restriction within the sleeve 106. An additional factor is the visibility of the individual droplets, which is a function of the droplet size and its ability to spread light .
[0206] Therefore, an effective trail must comprise one or more features described here to provide a visual indicator, as described in greater detail below. An important feature is that the trail comprises a sufficiently large number of liquid droplets or particles of a size that can be detected directly or that affects light by scattering in a similar way to fog to make them visible as a whole. In addition, a proportion of the trail large enough to be visible must rise sufficiently out of sleeve 106 to be seen and remain there for an appropriate length of time to provide visual confirmation of activation of dispenser 100. Accordingly, the tracks having the The following characteristics have been illustrated and correspond to the above criteria.
[0207] It was originally theorized that the size distribution within the trail needed to approach a mist, which usually requires a drop or particle size that exceeds about 50 microns (if the droplets are observed individually). In some cases, the droplet size can exceed about 40 microns. In other cases, the droplet size can exceed about 60 microns. In other cases, the droplet size can exceed about 70 microns. In other cases, the droplet size can exceed about 80 microns. In some cases, the droplet size can exceed about 50 microns.
[0208] Surprisingly, it was found that although the liquid properties impact the size distribution of the trail, the construction of the aerosol composition does not impact the size distribution within the trail since the droplets will spread light as long as they are in a range appropriately sized - microns to tens of microns - regardless of the liquid's construction.
[0209] For the trail to have a sufficiently visual contrast with the ambient air so that it can be observed, the trail must have a volume of at least 800 droplets / cm3 (assuming water concentrations of 0.0013 g / m3 of drops), which reduces the transparency and becomes visible. In other embodiments, the trail may have a volume of at least about 700 drops / cm3. In a specific modality, the trail has a volume of about 820 drops / cm3. In another embodiment, the trail has a volume of about 800 drops / cm3. In a different mode, the trail has a volume of about 810 drops / cm3. In an additional embodiment, the trail has a volume of about 840 drops / cm3. In an additional embodiment, the trail has a volume of about 860 drops / cm3.
[0210] Using several parameters described here, the droplet density within the air space enclosed by the sleeve can be estimated, assuming a homogeneous distribution of monodistributed droplets. In order to calculate the estimated droplet density, numerous attempts have been made. In particular, it is assumed that once the fluid medium has been released from the container, the portion of the fluid medium not deposited on the sleeve material droplets within the sleeve volume. It is also assumed that only the volume above the trigger nozzle is filled with droplets and that no droplet has left the volume defined by the sleeve yet. It is further assumed that the droplets fill the shadow area evenly and that all droplets are considered to be of medium droplet size measured by a 0.51 mm trigger nozzle at a height of 70 mm (approximately 20 microns). It is also assumed that all droplets are formed from Isopar L and that 20% by weight of the fluid medium discharged into the air space is Isopar L. The density of Isopar L is considered to be equal to 767 kg / m3 or 767 mg / cm3. Additionally, it is assumed that the sides of the sleeve are rectangular in shape, the top and bottom of the air space enclosed by the sleeve have a quadratic shape, and the amount of fluid distributed into the air space and not captured by the shadow is 100 mg.
[0211] The air space enclosed by the sleeve was estimated using the width of the sleeve section as 56 mm, the total height of the shade section is 172 mm, the height of the trigger nozzle (not the point of impact) as around 130 mm, and the volume of the closed air space as 407.68 cm3. The number of droplets within the air space was estimated assuming that 20 mg of Isopar L forms droplets with a diameter of 20 microns and that droplets with a diameter of 20 microns have a volume of 4.19 x 10-6 mm3. Each droplet is also assumed to weigh 3.21 x 10-6 mg. The total number of droplets estimated to be formed from 20 mg of Isopar L is close to 6.23 x 106. Therefore, the droplet density in the enclosed air space was estimated by dividing that number of droplets by the space of air enclosed by the sleeve. In this case, the estimated droplet density was 15,000 droplets per cm2. In addition, the number of droplets of 20 microns that would result in 100% saturation of a volume of 1 cm3 was calculated as 125,000,000. Therefore, the saturation level within the volume of air enclosed by the shade is estimated at 0.012%.
[0212] To form a trail having the characteristics shown here, a sufficient amount of composition is required. In particular, in one embodiment, at least about 100 mg of liquid composition forms the trail. In another embodiment, between about 75 mg and about 125 mg of the liquid composition form the trail. In an additional embodiment, between about 90 mg and about 100 mg of liquid composition form the trail. In a specific embodiment, about 100 mg of liquid forms the trail.
[0213] Additionally, the amount of liquid that is available to form the trail is determined, in part, by the speed of the jet. The speed at which the jet leaves the trigger nozzle 166 and subsequently impacts the sleeve 106 determines the balance between the liquid that is deposited in the sleeve 106 and that must be released as time and the liquid that forms the trail above the sleeve 106 indicating immediate activation. The amount of droplets that impact sleeve 106 is determined by the size distribution of the droplets and their speed. The larger droplets have a greater impulse, so that the gas flow is deflected by the sleeve 106, the larger droplets continue their trajectory and impact the sleeve 106. Smaller droplets have a smaller impulse and are transported by the flow. The speed of the gas flow changes the limit between the droplets that have sufficient momentum to reach the sleeve 106 and droplets that continue to be carried by the gas. The slower the gas flow, the greater the proportion that remains as an aerosol.
[0214] The interaction between a droplet and the sleeve 106 at the moment the drop impacts the sleeve 106 is influenced by the balance between the kinetic energy of the drop and the surface tension of the drop. Before the drop impacts sleeve 106, it basically includes kinetic energy. As the drop impacts sleeve 106, it is deformed and its surface energy is increased. Whether the drop remains on sleeve 106 or bounces depends on the balance of kinetic energy and surface energy. For moderate initial energies, as influenced by the droplet material and sleeve material 106, the droplet should bounce from the sleeve 106. For higher initial energies, the droplet should spread after impact.
[0215] The direction of the droplets as they exit the trigger nozzle 166 and travel towards the sleeve 106 determines the angle at which the droplets impinge on the sleeve 106. However, the kinetic energy of the droplet together with its surface energy and the surface properties of the sleeve material generally determine whether the droplet will bounce or adhere to the sleeve 106, rather than the actual geometry of the dispenser 100. However, in some cases, the surface morphology and geometry may be relevant if the droplet will be deposited or deviated from sleeve 106.
[0216] For the trail to be visible to the user, it must be visible above the height of the sleeve. Therefore, the trail moves at a speed that allows it to reach a height higher than that of the sleeve before the droplets are stopped by the friction of air and gravity and begin to descend towards the dispenser 100. The droplets having a diameter of 10 microns fall in speeds of about 1 cm / s and droplets having a diameter of about 50 microns fall at speeds of about 26 cm / s. In one embodiment, the fluid medium forms a trail that exits the upper end of the substrate 230 at a speed of between about 4 m / s to about 10 m / s. In another embodiment, parts of the trail extend at least 100 mm above the upper end of the substrate. In an additional modality, the trail has a speed of at least 0.10 m / s in 100 mm above the top entrance of the substrate.
[0217] The trail will be visible above the sleeve for a wide range of angles by the user. Inside the sleeve, the trail will only be visible to a user looking down and into the sleeve.
[0218] For the droplets to form a visible trail, it is also helpful that the evaporation rate of the droplets is low enough so that the droplets continue to spread light while the droplets are sufficiently dense to cause a visible effect. Evaporation is a function of material volatility, location temperature, and droplet surface area.
[0219] The trail generated by the distributor 100 and disposed there can be characterized by a dwell time, which is the time the trail remains visible inside or above the sleeve 106. The dwell time is an important visual tip for the user that the active formula has been distributed and is being absorbed into the substrate of the mango or emitted into the atmosphere. To form the trail, the base acts as a mechanism for discharging the fluid medium through substrate 230. In turn, discharging the fluid medium through substrate 230 and / or channel 242 results in a visible trail of the fluid medium.
[0220] After formation, at least a part of the trail is present within the channel 242 defined by the blanket 106, assuming that a sleeve 106 is being used with the base 102. In one embodiment, at least part of the trail travels out of channel 242 and is visible beyond a boundary of the substrate. The limit may be an upper limit, a lower limit, a lateral limit, or an imaginary limit formed by an open surface of the sleeve 106 (e.g., outlet opening 238). In one embodiment, the trail is visible beyond the substrate limit for at least 1 second. In another mode, the trail is visible beyond the substrate limit between 1 second and 2 seconds. In an additional mode, the trail is visible beyond the substrate limit for at least 3 seconds. In a specific embodiment, the trace of the fluid medium is visible beyond the limit formed by the outlet opening 238. In an additional embodiment, the substrate 230 comprises a shadow having a channel in which the fluid medium is visible as a trace for at least 3 seconds.
[0221] Dispensers without a sleeve have an immediate aerosol jet that typically persists for less than a second, and always less than 3 seconds. Because it contains the trace volume within the sleeve 106, the trace remains visible for 1 second or more. Preferably, the trail remains visible for more than 1 second, and in the preferred embodiment the trail is visible for at least 3 seconds. In another mode, the trail is visible for at least 8 seconds. In a preferred embodiment, the trail remains visible for about 8 seconds to about 16 seconds depending on a variety of factors. Perceptibly, the trail dwell time is different depending on the number of exit ports 190 used in the trigger nozzle 166 and / or discharge volume of the fluid medium.
[0222] Therefore, the trail generated by the dispenser 100 is characterized by a dwell time of between about 3 seconds to about 60 seconds, more preferably between about 5 seconds and about 30 seconds, and even more preferably between about 8 seconds and about 16 seconds on dispenser 100. In a particular mode, the dwell time is about 8 seconds using a dispenser 100 with the trigger nozzle 166 having four output ports 190. In a particular mode, the The trail's dwell time is about 14 seconds using a distributor 100 with a trigger nozzle 166 having six outlet ports 190. It is also contemplated that a trail can be generated with a nozzle having one or more ports, which may have a trail dwell time of 3 or more seconds.
[0223] An additional surprising feature of the trail generated by a trigger nozzle 166 with six exit ports 190 is the shape of the trail, which is different from the shape of the trail generated by a trigger nozzle 166 with four exit ports 190. In particular, the shape of the trail using a four-port trigger nozzle is generally characterized as a cloud. In contrast, the shape of the trail using a six-port trigger nozzle is characterized as a vortex. In one embodiment, the vortex trail moves through and out of sleeve 106 in a clockwise spiral pattern. Additionally, the vortex-like trail of the six-door trigger nozzle is visible only less than twice the time of the trail of the four-door trigger nozzle.
[0224] A characteristic related to the trail is the persistence time. The persistence time is an important visual cue to the user that the active formula has been distributed. Because it contains the trace volume inside the sleeve, the trace is observed above the sleeve for about 1 second to about 2 seconds. In one embodiment, the four-port outlet nozzle is characterized by a trail persistence time of between about 1.6 seconds to about 2.4 seconds. In another embodiment, the four-port outlet nozzle is characterized by a trail persistence time of between about 1.8 seconds and about 2.2 seconds. In an additional embodiment, the four-port outlet nozzle is characterized by a trail persistence time of about 2 seconds. In one embodiment, the six-port outlet nozzle is characterized by a trail persistence time of between about 1 second to about 1.4 seconds. In an additional mode, the six-port outlet nozzle is characterized by a trail persistence time of about 1.2 seconds.
[0225] Another characteristic of the dispenser 100 and associated components includes the amount of composition that is absorbed in the sleeve 106 for passive diffusion, compared to the amount of composition released into the atmosphere for active diffusion. In one embodiment, the amount of composition absorbed in sleeve 106 is between about 0.05 g to 0.4 g. In another embodiment, the amount of composition absorbed in the sleeve is between about 0.1 g and about 0.3 g. In an additional embodiment, the amount of composition absorbed in the sleeve is between about 0.1 g and about 0.2 g. In a different embodiment, the amount of composition absorbed in the sleeve is at least about 0.1 g and no more than about 0.5 g.
[0226] In one embodiment, the amount of composition released into the atmosphere is between about 0.2 g and about 2 g. In another embodiment, the amount of composition released into the atmosphere is between about 0.2 g and about 1 g. In an additional embodiment, the amount of composition released into the atmosphere is between 0.2 g and about 0.8 g. In a different embodiment, the amount of composition released into the atmosphere is at least about 0.2 g and no more than about 1 g.
[0227] Therefore, the ratio of the amount of composition absorbed in the sleeve compared to the amount of composition released into the atmosphere is about 1 to about 1. In another embodiment, the ratio of the amount of composition absorbed in the sleeve in comparison with the amount of composition released into the atmosphere is about 1 to about 4. In some embodiments, the ratio of the amount of composition absorbed into the sleeve compared to the amount of composition released into the atmosphere is about 1 to about of 6. In an additional embodiment, the ratio of the amount of composition absorbed in the sleeve compared to the amount of composition released into the atmosphere is about 1 to about 8. In different modalities, the ratio of the amount of composition absorbed in the sleeve mango compared to the amount of composition released into the atmosphere is about 4 to about 1. Additionally, the ratio decreases as mango 106 is reused through cycles d and additional drive.
[0228] A number of interrelated factors contribute to the performance of the dispenser 100, including the material of the sleeve 106, any surface treatment applied to it, the design of the trigger nozzle 166, the jet pattern emitted by the trigger nozzle 166, the location of the jet, the dosage amount, the concentration of active ingredient and the selection of the aerosol container 104 and the aerosol composition.
[0229] During and after activation, a plurality of indicators are provided through various characteristics of the distributor 100 that allow a user to determine whether the initial manual activation was successful and the continued effectiveness of the fluid medium. One or more of the indicators are provided in the form of a visual indicator and an audible indicator. Visual indicators are provided in at least three particular ways.
[0230] A first visual indicator is provided in the form of material selected for use as sleeve 106, previously discussed here. The sleeve material 106 provides an immediate tip to the user that the sleeve 106 is permeable and that an aerosol composition will be at least partially absorbed and thereafter passively emitted.
[0231] For the user to believe that the active material may emanate from the sleeve material, the material must provide one or more visual cues for both its fluid interaction and tactile properties. In particular, the material having a visible pore size and texture, and a fabric-like sensation suggests to the user that the material will behave like a fabric and allow a liquid to be absorbed by it and emanate from it.
[0232] Without being limited by theory, it is believed that the user's perception of the effectiveness of passive emanation from the sleeve 106 of the distributor 100 is based on the fact that he has been informed how the distributor works, observing a trail (described in details below), and perceive the sleeve material as something that appears to have the properties that would facilitate the operation of the dispenser 100. Therefore, a sleeve material 106 must comprise a material that provides the visual appearance of a material that will absorb a fluid to perform the emanation function, while at the same time having sufficient stiffness to form the sleeve 106.
[0233] The types of materials that users perceive to be absorbent are paper and other non-woven elements, along with woven fabrics and other textiles. Therefore, the sleeve material must exhibit visual properties characteristic of these classes of materials such as being fibrous, having pores, having texture, and having low density.
[0234] Additionally, the user can determine the perceived quality of the sleeve material 106 from the visual and tactile observations of the material. For example, for a material to be light and able to support itself like a sleeve 106, the material must have a low density and sufficient stiffness to avoid bending under its own weight, which provides the perception that the material may remain positioned inside. base 102. Additionally, the material must be resistant to damage and retain its texture and shape during handling (installation) and use (coating with the formulation, evaporation and emanation of the active ingredient).
[0235] A second visual indicator is provided in the form of a visible trail (see figure 23). In one embodiment, the second visual indicator may have a mist-like appearance. In this mode, the second visual indicator is visible for at least 3 seconds. In another mode, the visual indicator is visible for about 8 seconds to 16 seconds. In a different mode, the second visual indicator may look like a cloud or fog. In a further embodiment, the trail comprises a plurality of suspended particles or droplets. The activation of the dispenser 100 is immediately apparent to the user by the presence of a visible trail, above and / or inside the sleeve 106.
[0236] In many cases, the user can observe the trail as it leaves the exit opening 238 of the sleeve 106. Once the trail leaves the sleeve 106, the droplets can sink back into the volume closed by the sleeve 106 or they can be moved away from the sleeve 106 by the air flow. Since the trail is no longer restricted by the sleeve 106, it can grow through the air. As the trail enters the air and is distributed, the concentration of droplets or particles per unit volume in the trail will be reduced, thereby reducing the visibility of the trail until it is no longer visually perceived by a user. In some cases, the user can observe the trail inside the sleeve 106 due to a favorable viewing angle.
[0237] A third visual indicator is provided in the form of visible discoloration in sleeve 106 formed by the deposition of fluid medium therein. In one embodiment, the visual indicator appears to contrast in color with a surface adjacent to it. In a different mode, the visual indicator appears darker in color than an adjacent surface. In an additional embodiment, the third visual indicator provides a visual indication of effectiveness for a period of time that is longer than that of the second visual indicator (for example, the length of time that the trail is visible). In an additional embodiment, the visual indicator is created by a wet region in the absorbent structure (for example, the sleeve, conduit, substrate, etc.).
[0238] Numerous factors discussed previously are important for the user to be able to detect a wet area in sleeve 106 after activation. In particular, sufficient formulation must be deposited on sleeve 106 to create a visible change. Additionally, the wet area must be visible quickly after activation so that the user is still present to see it, and the wet area must last long enough so that the user has time to observe it. In addition, the wetted area must comprise a surface area large enough that one or more points 310 can be seen.
[0239] An amount of fluid medium deposited on the inner surface 132 of the sleeve 106 is actively diffused together with the fluid medium comprising the trail. However, a significant amount is provided in sleeve 106, which is passively emitted thereafter. In one embodiment, a distribution system includes a shadow having an internal volume and a mechanism for discharging a fluid medium. The discharge of the fluid medium in the shade prints a wet spot that is visible for a period of time t1, which is longer than a period of time t2 in which the fluid medium is visible when suspended in the atmosphere as a trail.
[0240] In another embodiment, a discharge stream of the fluid medium can be discharged onto a surface defining the channel, where an external surface of the substrate is printed with at least one wet spot that is more visually pronounced about 2 minutes after discharge. of the fluid medium. In addition, at least one discharge stream of the fluid medium can be discharged onto a surface defining the channel, and where an external surface of the substrate is printed with at least one wet spot having an average size of more than or equal to 8 cm2 ten seconds after the discharge of the fluid medium.
[0241] In an additional embodiment, a distribution system comprises a shadow and a base for retaining the shadow, where the discharge of a fluid medium in the shadow results in a visible wet spot of the fluid medium on a shadow surface for a period of time t1 and a visible trace of the fluid medium within the shadow for a period of time t2, and where t2 <t1. It is also contemplated that the visible trace of the fluid medium can be visible outside the shadow for a period of time of t3, where t3 <t2. In addition, it is also contemplated that the shade may comprise a nylon and that the visible wet spot is substantially not visible 6 minutes after the discharge of the fluid medium.
[0242] Numerous combinations of visual and / or audible indicators are provided. For example, in one embodiment, a delivery system comprises an absorbent substrate and a mechanism for discharging a fluid medium through the absorbent substrate. The discharge of the fluid medium creates an audible indicator that the fluid medium has been discharged. In addition, the discharge of the fluid medium through the absorbent structure also creates a first visual indicator in the form of a trail of suspended particles and a second visual indicator in the form of a wet region of the absorbent structure, which are visible by a user when using the distribution system. It is contemplated that the discharge of the fluid medium can be through or otherwise into a channel or conduit of the substrate.
[0243] In addition to visual indicators, one or more audible indicators are included. For example, a first audible indicator is provided in the form of any audible cue that is generally discernible by a user. An audible indicator is a "hiss" sound associated with aerosol dispensing systems. Other illustrative audible indicators include pressure fittings, beeps, pops, buzzers, voice, music and sound effects. In general, any audible tip capable of notifying a user of the distribution and / or a change in the distribution is suitable for use here. In one embodiment, the audible indicator is provided before the second and / or third visual indicators. In a different mode, the audible indicator is provided at substantially the same time as the second visual indicator. In another embodiment, the audible indicator is provided in a period of time when the dispenser 100 has stopped passively emanating the fluid medium. In a different mode, the audible indicator alerts the user that one of the second and / or third visual indicators has been closed.
[0244] It is seen that one or more of the indicators are used in combination to effectively communicate the active and passive emanation of the distributor 100. DATA AND EXAMPLES
[0245] Numerous non-limiting examples of the distribution system have been contemplated to demonstrate the properties discussed here. More particularly, the tests were conducted to demonstrate the impact that the selection of the properties relating to the container, the composition within the container, the base, and the sleeve, have on the distributor's distribution capabilities. The examples are provided for illustrative purposes only and should not be considered limitations of the present invention, since many variations are possible without departing from the spirit and scope of the invention, which would be recognized by one skilled in the art.
[0246] In the examples, all concentrations are listed as weight percent, unless otherwise specified. Countless examples below use materials considered for the mango, which are listed in Table 1 below. The materials referred to in the following examples are the materials listed in Table 1 unless otherwise noted. TABLE 1

[0247] The composition used in the following examples is the composition listed in Table 2 unless noted otherwise. In some examples as noted, 100% Isopar L is used, which is a high purity isoparaffin fluid manufactured by ExxonMobil Chemical.TABELA 2

[0248] A system having a distributor with a four-port trigger nozzle or a six-port trigger nozzle is considered. The distributor emits a trail according to the drive. The dwell time of the mist trail of a distributed composition enclosed within a volume of Nylon sleeve is considered for both types of actuator nozzles. With the sleeve on the dispenser, a timer was started as the base was manually pressed. The stopwatch was stopped when the trail was no longer clearly visible inside the sleeve, as seen from above. This test was repeated two more times, each time replacing the sleeve with a new, unused sleeve. The test was also repeated using a six-port trigger nozzle. Table 3 illustrates the results of the three tests for each trigger nozzle. TABLE 3

[0249] Thus, as previously noted, dispensers without a sleeve have a jet immediately transformed into an aerosol that persists for less than a second. Because it contains the fluid medium discharged inside a sleeve, a trace remains visible for 8 to 16 seconds, depending on the number of outlet ports on the actuator nozzle. It was further observed that the six outlet door trigger nozzle produced a trail that appeared to move in a clockwise spiral pattern while persisting. The trail produced with the six outlet door trigger nozzle lasted only less than twice as long as the trail produced with the four outlet door trigger nozzle.
[0250] A system comparing the weight of the formulation absorbed by the nylon sleeve with the weight of the formulation released into the atmosphere when the dispenser is activated multiple times is considered. The test was conducted by measuring the change in the mass of the sleeve and the container after activation. This test was only conducted on the nylon sleeve and separate sleeves were used for each test. The equipment used during the test included weighing scales +/- 0.001 gr, mango samples, and a formulation comprising 100% Isopar L.
[0251] The sleeve, container and base were all weighed separately and the results were recorded. The distributor was reassembled and activated (that is, triggered) twice in quick succession. The sleeve was removed and the weight of the sleeve was recorded. The container and base were weighed and the results were recorded. The steps were repeated, each time increasing the number of actuations by two in each repetition.
[0252] Table 4 illustrates the weight of the sleeve and container before and after activation. Table 4 also illustrates the mass of Isopar L absorbed in the mango x the mass of Isopar L released into the atmosphere. TABLE 4

[0253] The results in Table 4 illustrate that for up to ten activations of the device, the amount of formulation absorbed by the mango and released into the atmosphere increases linearly, where 0.046 grenades are absorbed into the mango in two activations and 0.333 grams are absorbed within the sleeve if the dispenser is activated ten times. Similarly, the mass of the spray formulation released after two jets is 0.242 grams, whereas if the device were activated ten times, 1.0218 grams would be released into the surrounding atmosphere.
[0254] These results suggest that the nylon sleeve material absorbs the formulation mass in a linear manner with the number of activation doses up to at least ten activations per user. Therefore, the user has a degree of control over the loading of the dough for formulation into the sleeve and subsequent release into the environment when operating the distributor.
[0255] An additional system is considered and quantifies and compares the persistence time of the trace observed above the sleeve material. Measurements were performed for both four and six outlet port nozzles. To conduct this test, two distributors were used, one having a trigger nozzle with four outlet ports and the other having a trigger nozzle with six outlet ports. Nylon sleeves were used, in addition to a high speed camera, fiber optic lights, high energy halogen lights and a tripod.
[0256] To conduct the test, the distributor having the formulation in Table 2 was positioned on a laboratory bench and illuminated by two high intensity halogen flow lights. The lights were only switched on directly before the measurements were taken and extinguished after each measurement in order to prevent the device from overheating. Additionally, the vapor trail was highlighted using a double optical fiber light source. The lighting allowed the trail to be additionally illuminated without additional heating and the steerable nature of the optical fibers allowed the lighting to be optimized.
[0257] The cameras were set to 500 frames per second and recorded for 3.3 seconds. To conduct the test, the sleeve was placed in the distributor with the four-port outlet nozzle. The halogen lights were turned on, recording was started, and the distribution base was pressed. The test was repeated using a distributor having a six-port outlet nozzle. The frames of the high-speed camera were stamped with a time stamp and revised for determination to give the trail a persistence time.
[0258] Table 5 illustrates the persistence time for the distributor with the four-port outlet nozzle and the distributor with the six-port port nozzle. TABLE 5


[0259] Thus, it can be seen from Table 5 that the distributor with the four-port trigger nozzle has an average trail persistence time of about 2 seconds, while the distributor with the six-port trigger nozzle output has an average trail persistence time of about 1.2 seconds.
[0260] Another system is considered to determine the maximum absorption capacity of various sleeve materials. In particular, the test considered the maximum absorption capacity of Isopar M in a variety of different sleeve materials.
[0261] The determination of the maximum absorption capacity of various mango materials has been achieved by measuring the change in mass when the mango is fully immersed in the Isopar formulation for a specified period of time. The change in the mass of the mango sample was used to calculate the maximum solution absorbed by the material's surface area. Samples of each of a variety of sleeve materials (nylon, PET film, coffee filter paper, polyester, and fiberglass) were prepared by cutting a square of approximately 20 mm2. Three samples were tested for each type of sleeve material.
[0262] The length and width of the sleeve sample through at least three points were measured and the mean was used. The surface area was calculated, the sample weight was measured, and the steps repeated for all samples. 4 ml of prepared formulation comprising Isopar was added to a container. The mango sample was placed in the formulation, ensuring complete immersion while a timer was started simultaneously. The mango sample was removed after 30 seconds to ensure that there is no excess of Isopar M. The saturated mango mass was recorded and these steps were repeated for each sample. The mass of solution absorbed per sample surface area was calculated. Table 6 illustrates the maximum mass absorption capacity of various types of sleeve materials. TABLE 6

[0263] Table 7 illustrates the average results of the maximum mass absorption capacity of the various types of materials. TABLE 7

[0264] Thus, glass fiber and coffee filter paper showed the highest maximum absorption capacity at 0.18 mg / mm2. The nylon showed a relatively high maximum absorption capacity especially compared to PET film. Reading the nylon shows that the nylon will act as an especially good reservoir for the formulation as it will accommodate a large amount of formulation without becoming too soggy.
[0265] With reference to Table 8, a system with various sleeve materials was tested to assist in determining the size of the wet area that is formed in the sleeve after activation. A controlled volume of 30 μL of Isopar L was used and samples of each of the five sleeve materials (nylon, PET film, coffee filter paper, polyester and fiberglass) were prepared using a sample size of at least 20 mm by 20 mm.
[0266] The sheet to be tested was placed on a glass plane, and Isopar L was retained into a pipette. Droplets of 30 µL of Isopar L were released into the mango sample from a height of 50 mm. The wet area was marked and photographed at the 10 second mark. The dimensions of the square were recorded and the test was repeated for each sample.
[0267] Table 8 illustrates the average wet area size (point) for various types of materials. TABLE 8

[0268] Thus, as illustrated by Table 8, nylon showed the largest average wet spot (point) size (8.00 cm2) and therefore has the greatest wetting capacity compared to Isopar L compared to others tested materials. The fiberglass showed the smallest size (4 cm2) of average wet area (point) and therefore had the lowest wetting capacity. These results suggest that the nylon sleeve has better absorption characteristics compared to other materials. It is also taught that a greater amount of composition is available for passive diffusion as a result of the nylon absorption characteristics as opposed to the composition being released into the atmosphere, through the trail, or otherwise. In addition, nylon has the added benefit of not swelling in the Isopar solvent and / or absorbing the active ingredient in the polymer itself, unlike polyester, and therefore, the active ingredient can be stored more efficiently in or in the shade 106 for a more uniform emanation.
[0269] Another system is considered in Tables 9 and 10 that illustrate the absorption time, percentage porosity, and porosity of various sleeve materials. These tests show the effects that material properties have on the interaction of the composition with the mango material, which results in the ability to calculate pore size values. The level of porosity (or empty volume ratio) is the percentage of the sleeve that is air, that is, the percentage of the sleeve that comprises pores.
[0270] The flow rate of an Isopar-based formulation comprising 100% Isopar M through a variety of different mango materials was the focus of this experiment. The absorption capacity of the sleeves was calculated, which was used to calculate the material's porosity ratio. The calculation was achieved by measuring the change in mass when the mango was saturated with the Isopar formulation. The percentage change in mass was theorized to be the percentage of porosity in the sleeve.
[0271] Samples of each of the five sleeve materials (nylon, PET film, coffee filter paper, polyester and fiberglass) were prepared by cutting a strip approximately 3 cm wide and 10 cm high from of the sleeve. The weight, height, length and width of each of the mango samples were measured. The sample was measured over at least three different points and the mean of the measurement was used. The mango density was calculated. These steps were repeated for each of the samples. 4 ml of Isopar was added to a container and the mass of the container with Isopar was recorded. One end of the mango sample was inserted into the container while simultaneously running the stopwatch. A piece of paper towel was placed on the end of the sleeve. The paper towel was monitored until the formulation started to soak in it, or until Isopar reached the end of the sleeve. The stopwatch was stopped and the saturation time was recorded. The mango was removed from the container and there was no excess of Isopar M. The saturated mango mass was recorded and the previous steps were repeated for each leaf sample.
[0272] Table 9 shows the absorption speed for Isopar M to absorb 100 mm of test samples, in addition to the mass of formula absorbed per sample surface area. TABLE 9


[0273] Table 10 illustrates the test data averages in Table 9 for each material. TABLE 10

[0274] As illustrated, coffee filter paper and nylon showed relatively high absorption values per surface area. The absorption speed of the coffee filter paper was more than twice that of the nylon. The test resulted in a large, but sparse, wet area (dot) on the coffee filter paper due to its increased wetting capacity which resulted in a faster and more inconsistent evaporation rate compared to nylon. The nylon showed a more localized and concentrated wet area (dot) compared to the coffee filter paper. Therefore, the results suggest that nylon has a lower, but more stable, evaporation rate.
[0275] A different system is considered with respect to the dosage for each distribution and the evaporation rates of various sheet materials. This set of experiments uses dispensers consisting of a sleeve, a container and a base. The container included a fluid medium having B-52 in an amount of 80% by weight, Isopar L in an amount of 18.964% by weight, and active metoflutrin in an amount of 1.036% by weight. The density of metroflutrin was shown to be 1.21 g / ml, the density of Isopar L was shown to be 18.96 g / ml, and the density of B-52 was shown to be 0.56g / ml . Additionally, the 300 mcl Summit valve was tested, in addition to the 185 mcl Aptar valve. The Summit valve was considered responsible for the distribution of 137 mg per jet and 1.37 mg of active ingredient per jet, 2.74 mg of active ingredient after two jets and 4.11 mg of active ingredient after 2 jets. The Aptar valve released 99.7 mg per jet and 0.997 mg of active ingredient per jet, 1.994 active ingredient for two jets, and 2.991 mg of active ingredient for 3 jets.
[0276] The mass of formula distributed in each dose was calculated. Since it is a very small mass, its mass has been calculated numerous times to increase confidence in the results. The experiment was carried out using a sleeve made of aluminum foil that acts as a non-absorbent control, a sleeve made of other materials to be tested (nylon, fiberglass, PET film, coffee filter paper, and polyester) , a composition container, a dispenser having a trigger nozzle with four outlet ports, a stopwatch, and a calibrated scale.
[0277] The balance was correctly aligned on a flat and level surface to calibrate it before conducting any measurements. The distributor was disassembled and the individual components were weighed and engraved. The container was weighed while on the base and the container was pressed while resting on the base. The dispenser was weighed and taped. Weighing and pressing were repeated approximately 10 times. The pressures occurred in rapid succession to avoid evaporation of any drops on the base. The residue was cleaned from the top of the base and the base was weighed again.
[0278] Using a distributor with an aluminum control sleeve, the individual components (base, container and sleeve) were weighed. The timer was started simultaneously and the base was pressed to release a dose. The sleeve was removed and weighed, while the time was recorded. The mango was kept on the scale and the dough was recorded at appropriate intervals (approximately every 30 seconds) until the difference between the dry and fully saturated mango returned to 10% of the original value. The used sleeve was removed and replaced with a new sleeve of a different material. All steps were repeated until each material was tested.
[0279] Table 11 illustrates the weight of the container, the amount of material, and the amount of active ingredient and solvent distributed in each of the tests. TABLE 11

[0280] The base was then cleaned and weighed again (87.2922 g) illustrating that less than 1.2 mg of the distributed composition remained in the base. The average mass of the composition distributed with each press was 135 mg, with 27 mg comprising the active ingredient and solvent.
[0281] From the chemical data provided for the container, the amount of active ingredient in each dose was considered to be 20%. Table 12 shows the mango mass over a selected period of time after coating with the composition. TABLE 12

[0282] The mass was calculated for each of the samples and the results appear in Table 13.TABELA 13

[0283] In addition to the results presented in Table 13, figure 24 illustrates the representation of combined evaporation for all materials.
[0284] Thus, the calculated mass of formula that adheres to or is otherwise absorbed into each sleeve is consistently between 25 mg and 30 mg. For all samples, this is estimated to be over 90% of the solvent and active ingredient distributed in each dose. In addition, the time for 80% of the formula to evaporate can differ significantly depending on the material. For example, it can take from 14 minutes for polyester to more than 30 minutes for aluminum foil. The nylon glass fiber samples showed stable release rate profiles of the deposited formulation over a suitably long period of 30 minutes compared to other materials tested. The stable release rate profiles suggest that these materials may be more consistent with respect to controlling the release of composition from the distributor.
[0285] With reference generally to figures 25 and 26, a dispenser having a nylon sleeve was used in conjunction with a container having a composition comprising propellant B-52 in an amount of 80% by weight, the solvent Isopar L in a amount of 18.81% by weight, and an active ingredient metoflutrin in an amount of 1.04% by weight, and an Eucalyptus oil in an amount of 0.15% by weight.
[0286] Several properties of the distributor were measured after activation. To conduct the test, the distributor was positioned on a laboratory bench and illuminated by two high intensity halogen lights. The lights were only switched on directly before measurements were taken and turned off after each measurement in order to prevent undue overheating of the device. Additionally, the vapor trail was highlighted using a fiber optic light source. This allowed the trail to be additionally illuminated without additional heating and the steerable nature of the optical fiber allowed the lighting to be optimized.
[0287] The drive properties and the resulting trail were measured using a high speed camera, MotionBLITZ Cube 2, supplied by Mikrotron GmBH. The camera was operated at a maximum resolution of 1280 x 1024 pixels and a maximum frame rate of 500 fps. The camera was mounted on a professional tripod to provide sufficient stability and was controlled by software that allowed for gain control and video acquisition. The data was saved in a raw binary format and then converted to .avi format without any compression. The frame and timing data have been saved embedded in the frame images. A scale rule was included in the images to provide a reference for further analysis.
[0288] The measurements were made in an air-conditioned laboratory where the temperature was around 21 C +/- 1.5 C and the humidity was around 71%.
[0289] The high speed camera was used to record the visible trail emanating from the top of the device after activation. A number of videos were recorded using different lighting and exposure settings to optimize the visibility of the ejected trail. The absorbent sleeve was then removed and more videos were recorded to represent the jets from four trigger nozzles. Again, the videos were recorded for various exposure and lighting configurations.
[0290] Figure 25 shows a single frame from one of the high-speed videos. The image was taken 146 ms after activation. The light rectangular area is the absorbent sleeve 106, which is excessively exposed due to the need to illuminate the trail. Two probes apparent in the image are the ends of the fiber optic lighting. The vapor trail that leaves the device about 146 ms after activation is clearly visible. By analyzing the video it is possible to measure the speed of the front of the trail.
[0291] The speed of the trail's front was measured using the video methods described above. Table 14 illustrates the estimated trail speed measured through the sleeve channel and then measured through 25 mm segments above the sleeve outlet. TABLE 14


[0292] Thus, the turbulent nature of the flow generates a wide range in the estimated values, but it can be seen that the flow reduces the speed by a factor of 10 in the first 25 mm above the screen.
[0293] In an additional test, the sleeve was removed from the distributor base and the above test was repeated with additional videos recorded. An aerosol jet was released from the dispenser. A single frame from one of the videos is illustrated in figure 26. A frame from the device's high-speed video is shown without the absorbent sleeve after the device is turned on. By analyzing the videos, estimates of the speed of the aerosol jet were obtained.
[0294] Table 15 illustrates the aerosol jet speed using a dispenser without a sleeve. TABLE 15

[0295] Table 15 illustrates that the aerosol jet flow is very turbulent, but the speed decreases from about 8 m / s at the driver nozzle to about 2 m / s at 250 mm from the driver nozzle.
[0296] Additionally, the operation of wetting the sleeve through the jet was always measured. The distributor was positioned on the laboratory bench and illuminated by a double optical fiber light source. The position, intensity and color temperature of the light were visually adjusted to maximize the visibility of the wet spot on the absorbent sleeve. Two series of measurements were taken, both looking down from above at an angle of about 30 °. The digital camera used was Canon PowerShot SX150 IS (PC1677). The camera was mounted on a professional tripod to provide high stability.
[0297] The measurements were carried out in an air-conditioned laboratory where the temperature was around 21 C +/- 1.5 C and the humidity about 73%.
[0298] Two series of photographs were taken. In both cases, an image was taken of the dried mango. Additional images were taken shortly after the jet was activated and then at subsequent intervals until the wet spot became difficult to discern. The first series of images was taken at intervals of 1 minute to 6 minutes after activation. It was clear that most of the initial spread of wetting occurred in the first minute, so that a second series of photographs was taken at intervals of 15 seconds to 1 minute, then in 2 minutes and then in 3 minutes. Finally, a new sleeve was inserted, the jet activated, and the size of the wet spot on the outside of the sleeve was measured 2 minutes after activation, where the point reached the maximum size while it was still reasonably defined. After 2 minutes, the stitch became less clear as it was absorbed into the sleeve.
[0299] The images were taken at intervals of up to 6 minutes after triggering and the wet spot was found to slightly increase in size from about 15 mm to about 25 mm in 2 minutes, and then became less defined and visible as the liquid has been absorbed.
[0300] The second sequence of images was taken at intervals of up to 2 minutes after activation and it was found that there was little variation in activation until 2 minutes since the wetting seemed to be instantaneous with the activation.
[0301] Additionally, the sleeve was visually inspected to confirm the results of the photographs. The results of the visual inspection of the wet spot on the outside of the absorbent sleeve matched substantially with what was photographed inside. Visual inspection allowed the wet spot size to be readily measured. The wet spot was approximately elliptical, being about 25 mm wide and about 35 mm high. The elliptical shape confirms that the jet of the actuating nozzle is tapered.
[0302] Turning to Table 16 below, a system is considered and illustrates the volume density, porosity and surface area of various sleeve materials. The sleeve materials that have been tested include nylon, coffee filter paper, polyester and fiberglass.
[0303] A BET surface area analysis was conducted on each of the mango samples. BET surface analysis uses a physical adsorption of gas molecules and a solid surface with removed gas. It assumes monolayer adsorption (that is, Krypton is used) and the results are a representation of the inverse relationship of the volume of the adsorbed gas against the relative pressure. From the relationship representation, the value c shows how strongly Krypton adheres to the substrate. The BET surface area in m2 / g of the material was also calculated.
[0304] A Mercury Intrusion Porometry (MIP) analysis was also conducted on each of the samples. MIP provides measurements regarding the distribution of pore size, pore volume, pore area and material porosity. Measurements were conducted using a Micromeritics AutoPore IV porosimeter, which is capable of measuring pore size distributions in the range of 0.003 μm to 600 μm (depending on the nature of the sample).
[0305] The helium density of the samples was also measured using helium pycnometry, which is used to measure the absolute density of a material. Helium density was measured using the Micromeritics Accupyc 1330 instrument.
[0306] Table 16 illustrates the surface area, median pore diameter, total intrusion volume, porosity, and helium density for nylon, coffee filter paper, polyester and fiberglass. TABLE 16

[0307] The results in Table 16 suggest that pores larger than 600 μm for the nylon sample may be present. Table 16 also suggests smaller pores for the coffee filter paper compared to the nylon sample, which is more likely due to the larger surface area of the coffee filter paper. In addition, Table 16 suggests that the polyester sample comprises very large pores, which may explain the variations between the absorption and release rates of the formulation applied to the polyester sample compared to the fiberglass and nylon samples.
[0308] With reference to tables 17 to 23, numerous distribution systems have been tested to determine the particle size measurements of the fluid medium after being distributed from several trigger nozzles. In particular, the particle size distribution of the aerosol jet and the trail generated by the sleeve from the four-port outlet nozzle were measured using a Spraytec laser diffraction system provided by Malvern Instruments using a 300 mm lens that allows measurement of jet particles and jet droplet size distributions in real time from 0.1 to 900 microns (Dv50: between 0.5 and 600 microns).
[0309] The four-port outlet nozzle of the distributor was fitted in a metered dose aerosol container of refill formulation without the presence of the device sleeve and was centrally mounted below the diffraction system measurement window. Malvern Spraytec laser, which ensured that the resulting jet passed through the measurement zone. The measurement capture program was run and the aerosol container was then activated using Malvern Spraytec Nasal Spray Accessory, thus spraying the aerosol through the incident beam of collimated laser light. The measurement was recorded and the particle size distribution calculated.
[0310] Each experimental sample measured for its aerosol droplet size distribution was measured at distances of 70 mm from the device's trigger nozzle to the collimated laser light beam, and again at 170 mm from the device's trigger nozzle to the incident beam of collimated laser light using the configuration as described above.
[0311] The distance of 70 mm is representative of the distance above the trigger nozzle for which the aerosol jet intersects with the surface of the sleeve in a fully assembled dispensing device. The 170 mm distance is representative of the distance above the trigger nozzle to the top edge of the sleeve on the fully assembled device.
[0312] Three samples of the four-port outlet nozzles with varying nozzle orifice sizes, listed below, were tested for their effects on particle size distribution using the method above.
[0313] The three trigger nozzles tested included a triggered nozzle for a molded prototype device with an output port diameter of 0.51 mm, an additional trigger nozzle with an output port diameter of 0.51 mm, and an trigger nozzle with an outlet port diameter of 1.2 mm.
[0314] A four-port trigger nozzle from the dispenser was fitted into a metered dose aerosol container of refill formulation without the presence of the device sleeve and was mounted below the measurement window of the Malvern Spraytec laser diffraction system. thus ensuring that the aerosol jet from only one of the four outlet ports of the actuator nozzles passes through the measurement zone during activation. The measurement capture program was run and the aerosol container was then activated using the Malvern Spraytec Nasal Spray Accessory, thus spraying the aerosol through the incident beam of collimated laser light. The measurement was recorded and the particle size distribution calculated.
[0315] Each experimental sample measured by its aerosol droplet size distribution was measured at distances of 70 mm from the device trigger nozzle to the incident beam and again at a distance of 120 mm, 150 mm or 170 mm from the trigger nozzle to the incident beam for the trigger nozzle samples (0.51 mm, 1.2 mm, and the additional sample 0.51 mm) using the configuration as described above.
[0316] Three samples of the drive nozzles having four outlet ports with varying outlet port sizes, listed below, were tested for their effects on particle size distribution using the method above.
[0317] The tested nozzles included a molded prototype device nozzle with an output port diameter of 0.51 mm, an additional actuator nozzle with an output port diameter of 0.51 mm and an actuator nozzle with an outlet port diameter of 1.2 mm.
[0318] The trigger nozzle having four outlet ports was fitted with a metered dose aerosol container of refill and sleeve formulation, and was centrally mounted 150 mm below the measurement window of the Malvern Spraytec laser diffraction system, thus ensuring that the resulting jet trail that leaves the sleeve volume passes through the measurement zone. The measurement capture program was run and the distributor was then activated, thus spraying the aerosol into the sleeve volume from where the resulting trail released the sleeve volume and passed through the incident beam. The measurement was recorded and the particle size distribution calculated.
[0319] Three samples of sleeve materials, listed below, were tested in combination with the base and the trigger nozzle having an exit port diameter of 0.51 mm for their effects on particle size distribution in the trail coming out of the sleeve volume using the method above. The tested sleeve materials include nylon, fiberglass, and polyester.
[0320] Table 17 illustrates the particle size distribution of the fluid product emitted from a first actuator nozzle having a diameter size of about 0.5 mm that emits a jet through four outlet ports. TABLE 17

[0321] Table 18 illustrates the particle size distribution of the fluid product emitted from a second actuator nozzle having a diameter size of 1.2 mm that emits the jet through four outlet ports. TABLE 18

[0322] Table 19 illustrates the particle size distribution of fluid product emitted from a third driver nozzle having a diameter size of 0.5 mm that emitted the jet through four outlet ports. TABLE 19

[0323] Table 20 illustrates the particle size distribution of the fluid product emitted from the first actuator nozzle having a diameter size of about 0.5 mm that emits the jet through an outlet port. TABLE 20

[0324] Table 21 illustrates the particle size distribution of the fluid product emitted from the second actuator nozzle having a diameter size of 1.2 mm that emits a jet through an outlet port. TABLE 21

[0325] Table 22 illustrates the particle size distribution of the fluid product emitted from the third drive nozzle having a diameter size of 0.5 mm that emits a jet through an outlet port. TABLE 22

[0326] Table 23 illustrates the particle size distribution of fluid product emitted from the third drive nozzle and measured after the particles come out of a sleeve through an upper opening thereof. The test was repeated for several sleeves. TABLE 23

[0327] Interestingly, the use of a shadow has resulted in a significant reduction in the particle size distribution compared to all types of nozzle. All nozzles were sprayed without a shadow to determine the particle size distribution at 70 mm and 170 mm. It was theorized that a measurement at 70 mm without a shadow (see Tables 18-22) would be commensurable with a distance that needed to be covered for the aerosol jet to impact an internal surface of the shadows that were tested, the results that are illustrated in Table 23. All nozzles that were tested without a shadow were found to have significantly larger particle size distributions, for example, Dv (90) distributions from about 41 μm to about 250 μm for 4 jets and about 67 μm at about 121 μm for a single jet, than found with the particle distribution measured in an exit of the nylon and fiberglass shadows that showed Dv (90) distributions of about 29 and 25 μm, respectively. The polyester shade resulted in a Dv (90) distribution of about 43 μm.
[0328] Additionally, it was also theorized that a measurement of 170 mm without a shadow (see Tables 18 to 22) would be commensurable with a distance that must be covered for the aerosol jet to come out of the shadows that were tested, the results of which are shown in Table 23. All nozzles that were tested without a shadow were found to have significantly larger particle size distributions, for example, Dv (90) distributions from about 38 μm to about 39 μm for 4 jets ( the second nozzle does not generate a detectable jet since the particles did not travel as high) and about 69 μm to about 92 μm for a single jet, than found with the particle distribution measured in an exit of the nylon and fiber shadows glass that showed Dv (90) distributions of about 29 μm and 25 μm, respectively. As noted earlier, the polyester shade resulted in a Dv (90) distribution of around 43 μm.
[0329] Additionally, it was also theorized that a measurement of 170 mm without a shadow (see Tables 18 to 22) would be commensurable with a distance that needs to be covered for the aerosol jet to come out of the shadows that were tested, the results of which are illustrated in Table 23. All nozzles that were tested without a shadow were found to have significantly larger particle size distributions, for example, DV (90) distributions from about 38 μm to about 39 μm for 4 jets (the second nozzle did not generate a detectable jet as the particles did not travel as high) and about 69 μm to about 92 μm for a single jet, than found with the particle distribution measured at an exit from the nylon shadows and glass fibers that showed Dv (90) distributions of about 29 μm to 25 μm, respectively. As noted previously, the polyester shade resulted in a Dv (90) distribution of around 43 μm.
[0330] Additionally, the test provided a view of the percentage of particles that had less than 10 μm. Regardless of whether a single jet or four jets were made from any of the nozzles, the percentage range of particles having a size of less than 10 μm was about 1% to about 22% as measured at 70 mm and about from 20% to about 24% as measured at 170 mm (the second nozzle did not generate a detectable jet as the particles did not travel as high). In contrast, all leftovers tested resulted in a percentage of total particles that was less than 10 μm, at least 28% and up to 43%.
[0331] It is therefore contemplated that the inclusion of a shadow, substrate or channel has a significant impact on the particle size distribution that comes out of the upper end, exit or opening. In fact, it is contemplated that a substrate having a conduit with a fluid medium discharged therein comprises a particle size distribution that is less than or equal to 30 μm for a particle size distribution Dv (90) at an outlet of the channel, less than or equal to 15 μm for a Dv particle size distribution (50) at one outlet of the channel, and / or less than or equal to 6 μm for a Dv particle size distribution (10) at one outlet of the channel. Additionally, it is also contemplated that a substrate having a conduit with a fluid medium discharged therein comprises a particle size distribution in which at least 15% of the particles are less than 10 μm in size, at least 25% of the particles are less than 10 μm in size, at least 30% of the particles are less than 10 μm in size, at least 35% of the particles are less than 10 μm in size, at least 40% of the particles are less than 10 μm in size, and / or at least 45% of the particles are less than 10 μm in size.
[0332] It is also contemplated that other types of accommodation, for example, telescopic accommodation or accommodation using electronic elements, may similarly encompass the characteristics perceived above. For example, the electromechanical delivery systems described in US patent application No. 11 / 725,402 and 11 / 893,532, can be modified to include a natural appearance to provide the impression that the dispenser does not include any or all of the man-made features as noted above. For example, the dispenser can be fully or partially printed with a natural-looking pattern, reproducing the shape of a naturally occurring object, or formed from a naturally occurring object. However, it must also be contemplated that other bases can be made of different materials such as pebbles, stones, fossilized articles, etc.
[0333] In some cases, materials are selected from or include manufactured materials configured to approach naturally occurring substances, such as wood, stone, paper or rock or combinations thereof. Any of these materials can be selected based on their natural appearance and / or a natural feel to the touch. By incorporating natural materials, or analogues of natural materials, dispenser 100 can be created to have a more suitable appearance for placement outdoors, such as in a solarium or on a balcony, or patio, or can complement the appearance and feeling of natural objects inside the house.
[0334] In some embodiments, a lid (not shown) may be included to cover at least partially the dispenser 100. In one embodiment, the lid is printed with a grid-like configuration containing openings through it. In other embodiments, the cover may have an interlacing, screen, or woven configuration that approximates the porosity of the grid-like configuration. In one embodiment, the sleeve 106 and the cap are formed of a rigid material to allow a user to grip the dispenser 100 by the sleeve 106 without causing it to disassemble.
[0335] Additionally, the inner surface of the sleeve 106 may have various textures and / or surface patterns, such as a rough surface, a smooth surface, a channeled surface, and combinations of them that can affect the angles of deviation which, for in turn, may impact the amount of deposition on the inner surface of the sleeve in addition to the amount of bypassed composition. Additionally, increasing or decreasing the speed of the currents and / or providing some type of measuring device can assist in varying the amounts of composition distributed into the first, second and third quantities, respectively.
[0336] In other modalities, it is contemplated that other surface markings, interruptions, and / or surface irregularities can be provided on the sleeve, integrally with or as a separate component, to affect the distributor's distribution properties. For example, it is envisioned that baffle plates, ribs, or other components can be added to the inner surface of the sleeve to assist in distribution and / or direct a certain amount of composition to the trail or to the inner surface of the sleeve. In addition, other elements can be supplied at the distributor that assist in the formation of the trail.
[0337] In additional modalities, the distributor can incorporate more complex components that assist in the operation of the distributor. For example, additional and / or alternative mechanisms can be used to release the aerosol composition from the container. In this modality, a mechanical and / or electromechanical system can be used by activating the distributor in response to a past time interval determined by a timer (not shown) and / or a signal from a sensor (not shown), such as a temperature sensor. motion or other type of sensor.
[0338] In an implementation, a sensor can be a light perception element, such as a photodetector, or it can be a sound detection element, such as a microphone. In this mode, the distributor can be activated, for example, by entering the user in an environment where the distributor was placed. In this case, the sensor detects the user's input, which then triggers the activation of the dispenser to release a metered dose of the composition from the container. In one embodiment, the distributor can incorporate a solenoid (not shown) powered by batteries (not shown) that releases the metered dose of the composition.
[0339] In additional modalities, the use of one or more lights in the distributor is contemplated. For example, a light can be provided in a part of the distributor. In one embodiment, the light can correspond to the effectiveness of the fluid medium being emitted. For example, the light can be illuminated while the fluid medium is present in the sleeve and / or is being passively diffused. The light may fade or otherwise dissipate as the fluid medium is diffused passively. The light can extinguish when the passive diffusion is complete or substantially complete. It is further contemplated that a light may be provided to illuminate the wet area in the sleeve and / or to assist in illuminating individual fibers of the sleeve. The distributor can also operate as an independent light.
[0340] In a different mode, the dispenser can be used in an inverted way so that the dispenser can be hung or otherwise suspended. In this mode, a cord or other mechanism may need to be provided to activate the distributor.
[0341] In other modalities, the dispenser can be operated in a way that allows a user to manually spray the dispenser. For example, a container having a composition and a suitable spray can be provided to the user separately. The user can spray one or more parts of the inner and / or outer surfaces of the sleeve to provide passive diffusion capabilities. In this case, the user may wish to spray an upper part of the sleeve so that a part of the composition is actively released and a part of the composition is directed to the sleeve for passive diffusion. Thus, the mango can be dosed with the composition through user intervention. In a different embodiment, the sleeve may be able to be dosed through a container disposed inside the base of the dispenser, in addition to by manually spraying the outside of the sleeve.
[0342] In a different mode, the amount of fluid product distributed in a drive cycle can depend on numerous factors. For example, an amount of fluid medium can be discharged at a specific rate and a second amount of fluid medium can be discharged at a different rate. The amount and speed of the fluid medium discharged can be related to the frequency at which the distributor is activated (for example, in sequential actuations, within a certain time frame in relation to the last actuation, etc.).
[0343] Container 104 may be an aerosol container, a pump type spray, and the like. Additional examples of reservoirs, activation mechanisms, compositions, substrates and the like that can be used here include those described in U.S. Patent Nos. 7,837,065, 8,061,562 and U.S. patent applications Nos. 11 / 801,554, 11 / 893,456, 11 / 893,489, 11 / 893,476, 11 / 805,976, 11 / 898,456 and 11 / 893,532.
[0344] Any of the terms "fluid medium", "composition", "formulation" and the like are used interchangeably and should not be limiting. Instead, the terms must be inclusive of any substance in any form (for example, liquid, gas, solid, etc.) that can be distributed or otherwise emitted.
[0345] The term "through" as used here, generally means a path taken by the fluid medium from base 102 along or into channel 242 or conduit to the upper opening 238 or exit. In contrast, when discussing the fluid medium being directed "through" a wall of the sleeve 106, this means that the fluid medium is discharged directly all the way through the fibers of the sleeve 106 by overcoming the strength of the fiber of the sleeve 106 in opposed to absorption in the fibers of the sleeve 106 and being emitted passively thereafter.
[0346] Additional features included here include usage indicators or usage tips. For example, in a embodiment where the volatile active ingredient is distributed to the inner surface 232 of the sleeve 106, an ink is supplied within the sleeve 106 which may appear or disappear to indicate when the volatile active ingredient has been completely evaporated. Combinations of inks appearing and disappearing are contemplated to create more complex characteristics after the application and gradual emanation of the volatile active ingredient from the dispenser 100. Other usage tips can be employed, including, for example, a liquid / gel container that is peeled for activate paints that use capillary action or absorb this active ingredient after removal or pressing together with an absorbent layer, a disc to set a date, or an area to write the activation date, etc.
[0347] In another embodiment, the distributor 100 may incorporate a mechanism to increase the emanation rates such as a heater and / or a fan or other means as known in the art.
