    device for dispensing a liquid and method of dispensing and spraying it in the exemplary configurations of the present invention, flairr-based aerosol-like devices may be provided. These devices use a combination of flairr technology, pre-compression valves and aerosol-type pressurization of the dispensed liquid. said dispensing device has a main body comprising a pressure chamber being provided with a pressure piston and a pressure spring. the device still has a piston and a piston chamber that draws liquid from a reservoir and fills the pressure chamber with that liquid when a user pulls the trigger in various impulses and compression and relaxation. the piston chamber has both an inlet and an outlet valve. in a distribution head a valve is provided to regulate the flow resistance preventing leakage. once the liquid is sufficiently pressurized, it can be dispensed by a user by opening an activation valve, like pressing on an activation button, and spraying can be abruptly stopped by a user ceasing to press the button. or, for example, in alternative configurations without an activation button, once the liquid is sufficiently pressurized, continuous spraying will occur until the pressure chamber is completed. by repeatedly pumping the trigger before the pressure chamber is completely completed, continuous spraying can be achieved. by configuring the inlet volume to be vastly higher than the volume of the pressure chamber, continuous spraying with smaller pumping impulses can be implemented.

    [0001] This application claims the benefits of North American Provisional Patent Applications Nos. 61 / 343,977 required on May 5, 2010 and 61 / 456,349 required on November 4, 2010, the description of each of which is incorporated herein by reference.
    [0002] The present invention relates to distribution technologies, and in particular to a spray device that can put liquids under pressure and distribute them in a manner equivalent to that of an aerosol device or can either use it in a controlled manner, or way as continuous spray.
    [0003] Liquid dispensing devices such as spray bottles (spray) are well known. Some offer pre-compression to ensure strong spraying when the trigger is pressed and preventing leakage. Sprayers can be easily manufactured and filled, and are often used to distribute cleaners of all types, for example. However, in many circumstances, it will be preferred not to have to continuously pump a dispensing device by pressing the dispensed liquid. Thus, aerosols are well known. Aerosol retainer of a liquid or other dispensed under pressure so that when the user activates the device (for example, pressing a button) the pressurized content may escape. However, aerosols present significant environmental hazards as well as packaging disruption, which result from the need to use an aerosol propellant in them, and also the need to pressurize them. This requires filling said devices under pressure, using suitable packaging strong enough to withstand the pressure, and maintaining steps to ensure that the propellant maintains a uniform pressure over the life of the can or container. Such conditions often require the use of non-ecological materials and ingredients.
    [0004] To overcome these drawbacks, it will be necessary, according to the state of the art, to have a spray device that can provide aerosol of the functional type without the numerous drawbacks of current aeroosols.
    [0005] In exemplary configurations of the present invention, "Flairsol" dispensing / dispensing devices may be provided. These devices use a combination of Flair® technology, pre-compression valves and aerosol type pressurization of the dispensed liquids. Said dispensing device has, for example, a main body comprising a pressure chamber, being provided with a pressure piston and a pressure spring 5. The device also has a piston and a piston chamber that draws liquid from a container, for example the inner container of a Flair® bottle, and filling the pressure chamber with that liquid that a user pulls a trigger in several compression pulses. and relaxation. The piston chamber has an inlet valve and an outlet valve, which serve to prevent backflow. In exemplary configurations of the present invention, these valves may be combined with a single dome valve. The outlet valve part of the dome valve allows liquid to escape from the pressure chamber under pressure (supplied by the user pumping the trigger) to enter a central vertical channel that is in fluid communication with the pressure chamber (above the pressure piston) and the membrane valve that leads to the outlet channel and nozzle at the top of the dispensing head. Said upper outlet valve (for example, the membrane valve and / or a transport valve) may be provided to regulate the flow resistance and prevent leakage.
    [0006] In an activation button configuration, for example, once the liquid is sufficiently pressurized, it can be dispensed / dispensed by a user by releasing the upper outlet valve by pressing a pressure button. In alternative configurations of the present invention without an activation button, for example, known as “continuous spray” configurations, once the liquid is sufficiently pressurized, continuous spraying occurs until (i) the pressure chamber is completed or (ii) until the pressure of the liquid in the pressure chamber (including the central vertical channel) slows down below the opening pressure of said upper outlet valve. This usually occurs at the same time, as exemplary systems are designed so that the pressure spring always provides sufficient force to overcome the upper outlet valve, and then the upper outlet valve only works to stop dripping once the pressure chamber has been filled with fluid.
    [0007] For a better understanding of the invention, detailed reference will be made to it, with respect to the attached drawings, presented in an exemplary and non-limiting character, in which: - Figure 1 represents two configurations of a Flairosol device according to the present invention; - Figure 2 represents an example of a "activation button" configuration of a Flairosol device according to the present invention; - Figure 3 represents an enlarged upper part and a longitudinal cross section of it of the exemplary device of Figure 2; - Figure 4 also shows details and variations of the membrane / transport valve and dome valve assembly in an exemplary configuration of the “activation button” Flairosol; Figures 5 and 6 illustrate an exemplary release or impulse of fluid entry from the exemplary Flairosol device of Figure 2 according to exemplary configurations of the present invention; Figures 7 and 8 illustrate a subsequent compression or flow of the fluid in the pressure chamber impulse of the exemplary Flairosol device of Figure 3 according to exemplary configurations of the present invention; - Figure 9 illustrates the exemplary Flairosol device of Figure 3 with a pressure chamber completely filled and the spring under the pressure piston being compressed to this lowest position, according to exemplary configurations of the present invention; - Figure 10 shows the exemplary Flairosol device of Figure 2 once the activation button has been pressed, the membrane valve then released the spraying started in accordance with exemplary configurations of the present invention; - Figure 11 shows the exemplary Flairosol device in Figure 2 where spraying has stopped, and the activation button having been released (left panel) or the liquid pressure dripping below the opening pressure of the membrane valve (right panel), and thus stopping spraying according to configurations of the present invention; - Figure 12 represents exemplary configurations of the “continuous spraying” Flairosol according to exemplary configurations of the present invention; - Figure 13 represents a longitudinal cross section and an enlarged upper part of it of the Flairosol “continuous spraying” device of Figure 12; - Figure 14 also shows details and variations of the FIairosol spray configuration in Figure 13; - Figure 15 shows an initial release or impulse of fluid entry from the exemplary continuous spraying device Flairosol of Figure 13 according to exemplary configurations of the present invention; - Figure 16 illustrates a subsequent compression or flow of the fluid in the pressure chamber pulse of the exemplary Flairosol device of Figure 13 according to exemplary configurations of the present invention where continuous spraying has started; - Figure 17 illustrates a consecutive impulse to release the exemplary Flairosol device of Figure 13, where p liquid is pressed out of the pressure chamber through the orifice and the liquid is still drawn from the piston chamber; e - Figure 18 represents a stoppage of spraying in a Flairosol spray device according to exemplary configurations of the present invention, where once the liquid pressure is too low to create a good spray, the membrane valve deforms from its original state and blocking the liquid.
    [0008] In the exemplary configurations of the present invention, a liquid spray device offers the benefits of both a liquid spray and aerosol device. This exemplary device is referred to here as the “Flairosol” device, as it uses the “bag within a bag” Flair® technology developed and provided by Dispensing Technologies BV of Helmond, Netherlands and combines the technology with means to internally pressurize the liquid before ed spray to stimulate aerosol devices.
    [0009] It should be noted that the features described here may, for example, be implemented without Flair® “bag in a bag” technology and thus exemplary configurations of the present invention will not be strictly limited to this. implementation of a non-Flair® technology may be more expansive in broader terms for production and use. Flair® “bag in a bag” technology, which motivates the inner container to decrease 'around the pressure chamber and the inlet tube, thus avoiding the idle space in the inner container, avoiding the need for u create a full-length tube for the liquid container in the lower part of the unit to prevent crimping and failure to distribute the entire contents. The technology applied to the pressure applied to the inner bag results from a displacement m and n t the medium that is provided between the inner container and the outer container (for example, air ') and direct ventilation of the liquid container is not required.
    [00010] In exemplary configurations of the present invention, a dispensing device may be fitted with an internal pressure chamber. The liquid to be dispensed may be motivated by potential energy, including, for example, a gas or air or spring shock absorber of various compositions and materials, and the like. In some exemplary configurations of the present invention, said pressure in the pressure chamber may, for example, reach approximately three (3) - five (5) bar. In other configurations it can be 10-20 bar, for example, and in other d500- 800 millibar, for example. Everything depends on the liquid dispensed, its viscosity, the fineness of the desired spray, etc. Further details of the pressure chamber and the pressure spring and their movement will be described below in connection with Figure 3.
    [00011] Once the liquid is pressurized in the pressure chamber, a user will be able to release an outlet valve and the liquid sprayed. In the exemplary configurations of the present invention, a central channel can be provided above the pressure chamber and is in fluid communication with the pressure chamber and the upper outlet valve, ultimately leading to a spray nozzle. In view of the outlet valve having a minimum “deformation pressure”, a certain minimum pressure is required before any liquid is sprayed, thus providing spray consistency and non-leak characteristics of a pre-compression system. The minimum deformation pressure can, and several exemplary configurations, be varied by the thickness, shape, composition and strength of the valve. In some exemplary configurations of the present invention, the minimum strain pressure may be low, for example% bar, for a system where the pressure spring varies between 3-5 bar as its minimum and maximum function of compressions within the pressure chamber, for example. Thus, in the aforementioned configurations, while the pressure spring currently controls the outlet pressure of the liquid, when the user releases the activation button, or the pressure chamber is filled, the upper outlet valve helps to have a “hard stop” fluid flow, and thus preventing diving or leakage at the end of a spray. As noted below, given that there are two valves operating in repair, a liquid inlet channel into the pressure chamber (for example a dome valve) and keeping it under pressure, and another flow or spray channel from the upper outlet channel. (for example a membrane valve), a variety of different controls for various liquids in various contexts can be implemented. Details of the invention will be described below in connection with Figures 1 to 18, in which Figures 2-11 describe a first variant “Activation Button” Flairosol, where an activation button must be released to release the liquid to be sprayed, and where Figures 12-18 represent a second variant “Activation Button” Flairosol, where a minimum pressure of the liquid is reached, the liquid spraying continuously until the pressure chamber is filled. In another variant, Flairosol involves the combination of one or more members of a pre-compression valve, a Flair® bottle (internal container and external container with average displacement between them) and a pressure chamber that can store mechanical energy in a device spring-loaded or resilient.
    [00012] Figure 1 shows exemplary form factors of each of the two exemplary versions of Flairosol devices according to exemplary configurations of the present invention. On the left side of a version of the “Activation Button” it is fitted and on the right side, a version “Continuous spraying” is shown. Each version can be used in appropriate contexts as described more fully below.
    [00013] A. Flairosol Using Spray On / Off Figure 2 represents an exemplary button for activating an exemplary configuration. Even if the liquid has been sufficiently pressurized, the activation button version will only spray when the user presses an activation button, and thus all spraying under the user's granular control. Here an activation button can be provided at the top of the device, for example. The trigger is used to internally generate pressure on a part of the liquid in a pressure chamber, thus storing enough energy to allow the liquid - once pressurized - to spray under pressure. Once the liquid in the internal pressure chamber is sufficiently pressurized, a user can press the activation button which then allows the liquid to spray outside the outlet channel.
    [00014] Figure 3 shows details of the exemplary activation button for the Flairosol device in Figure 2. The device is a combination of a pre-compression vaporizer, a Flair® bottle and a pressure chamber / buffer. The activation button 310, the membrane valve 320, the transport valve 315, a piston chamber 335, a central vertical channel 325, the dome valve 340, the trigger 350, the pressure piston 360, the spring are shown pressure 365, the pressure chamber 370 and the inlet pipe 380. In exemplary configurations of the present invention, piston 330 can be driven, for example by the trigger or lever 350, which itself can be connected to piston 330, for example, a pivot arm anchored at one point, or by another suitable transfer / connection force mechanism. Said operation of the trigger 350 pressurizes a part of the liquid, as described below.
    [00015] It should be noted that piston 330 does not necessarily need to be oriented vertically as shown, but it can still be oriented in a variety of directions when necessary. For example, instead of having the piston move until it fills the piston chamber and goes down to fill as shown, the reverse can, for example, be done, or several horizontal movements can be implemented, as is commonly done in vaporizers. If reverse vertical orientation is implemented, for example, and the piston lowers to fill the piston chamber and moves upwards to fill it, then any air bubbles that are mixed in the liquid can float on top of the piston chamber in a deliberate impulse (when the piston chamber fills) and be easily purged in the subsequent compression pulse (when the piston chamber is filled).
    [00016] It should be noted that the deformation pressure of the valve port inlet in the pressure chamber, for example the dome valve 340 can always be greater than the maximum pressure of the pressure chamber of the container. In this sense, said dome valve, for example the absolute boss. The dome valve must then withstand any pressure developed in the pressure chamber, for example. It should also be noted that a valve can, for example, be divided into two valves, one acting as an inlet valve in the piston chamber and the other acting as a porter of the pressure chamber / central channel.
    [00017] It should be noted that as the liquid is not compressible, as long as there is liquid in the central channel above the pressure chamber, if the pressure spring 365 is still compressed in any form and thus releasing a force, in the exemplary configurations of the present invention , the liquid will flow out of the membrane valve 320 if the activation button is pressed. This is because in the exemplary configurations of the present invention the pressure chamber 370 can be designed so that it is always less than the length of the pressure spring 365 in its complete extension, without any compression. Thus, when the pressure spring 365 has some compression, an excess pressure of the opening pressure of the membrane valve 320 may be generated. If this is not the case, the pressure piston will never be able to extend to the top position of the pressure chamber and part of the liquid volume in the pressure chamber will never be expelled and then wasted. Although systems can be designed within the present invention, it is not an ideal use for resources. Thus, in general, the opening pressure of the membrane valve 320 is at least important to operate the pressure spring 365.
    [00018] Thus, the pressure spring can be designed, for example, to always be compressed to some degree inside the pressure chamber, both in the uppermost position of the pressure piston (complete liquid pressure chamber), where the spring force pressure release to be F1, and the lower position of the pressure piston (pressure chamber filled with liquid), where the force pressure spring release being F2, where F1> F2, and both F1 and F2 being greater than F0 (no force released by the pressure spring, at its maximum length, where there is no compression). In this way, the pressure of a liquid being sprayed from the device will vary linearly sometimes between F2 and F1 when spraying continues. For example, if the pressure spring 365 at its maximum compression inside the pressure chamber 370 releases 5 bar, and at its minimum pressure inside the pressure chamber releases 3 bar, the spray will always vary linearly between 5 and 3 bar. As described below in connection with Figure 9, an exemplary system does not allow the pressure spring 365 to be over-compressed and thus making it possible to be damaged through the flow hole 910. Figure 9 represents the two valves used in the exemplary configurations of the present invention , a dome valve 340 that regulates the entrance to the internal piston chamber, and a transport valve 325 and the membrane valve 320, which together operate as an upper outlet valve, and thus opening the outlet in the flow channel and in direction to the mouthpiece. As shown on the right side of Figure 4, if the pressure generated in the pressure chamber is large (as for a viscous liquid, or for example, where a fine mixed spray is desired), the dome valve 340 can be reinforced by an additional spring 340. Similarly, additional spring 327 may be added to the transport valve 325 to increase the opening pressure. Figures 5-6 show an impulse to release or enter the exemplary Flairosol device in Figure 3. The right image in Figure 5, and a projection of it in Figure 6, represents details of piston chamber 335, piston 330 and a fluid in said release impulse. The trigger 350 can be loaded with a spring (integrated plastic spring) as in a standard vaporizer. When the trigger is moved externally (see black arrow in the right image of Figure 5), the piston is moving up and beyond the device, and liquid is being sucked into the piston chamber, as shown by the arrows in the center of Figure 6 flowing to near dome valve 340 to piston chamber 335. The current liquid flow path is behind the central vertical channel 325 leading to the outlet channel at the top of the device, not shown in Figure 6. As shown in 610 , the liquid passes the inlet valve 650 of the dome valve (see the upper and lower right part of the dome valve), and then passes through a channel (not shown) in piston chamber 335. It should be noted that face if the liquid is removed from the piston chamber in its release impulse it is not pressurized (as it comes from the body of the inner container or bottle and not from the pressure chamber), it will be impossible to overcome the sealing of the dome valve and proceed in the channel output. Thus, the dome valve closes the outlet channel, as shown in 610.
    [00019] Figures 7 and 8 illustrate an exemplary compression pulse in the exemplary Flairosol device of Figure 3 according to the exemplary configurations of the present invention. A user presses down on trigger 350, causing the piston chamber to deflate, and forcing the liquid to descend and out of it, towards the dome valve. Here, the liquid is forced to return through the same channel through which it enters the piston chamber, shown again by the dashed arrow line in the center of Figure 8. It should be noted that multiple channels can be used, for example, for reasons of security. The inlet valve on the dome valve prevents the liquid from returning to the bottle via the intake line, as shown in Figure 8 in 810, but now, as the liquid is pressurized, the dome valve flexes opening against the pressure of the liquid, allowing the liquid to enter the pressure chamber, and move upward in the central channel towards the membrane valve above, as shown in Figure 8. At the top of the device, as shown in 710 in Figure 7, the liquid pressurized is blocked by the activation button keeping the membrane valve closed. When the liquid enters the pressure chamber, the spring under the pressure piston is then compressed, as shown in 720, in the right image of Figure 7.
    [00020] Figure 9 illustrates the exemplary Flairosol device in Figure 3 with the pressure chamber completely filled and the pressure piston spring being in its maximum compressed state (as defined by the configuration - obviously the spring shown may be even more compressed), according to exemplary configurations of the present invention. It should be noted that when the pressure chamber is filled, due to an under pressure being created inside (inside) the Flair® bottle, air is sucked between the Flair® layers (ventilating) as shown at the bottom of Figure 5 ( left image), as the space between the outer surface of the inner Flair® bottle, and the inner surface of the outer Flair® bottle (referred to as the space shown in the blue display of Figure 9), being opened at ambient pressure through this ventilation. Returning to Figure 9, if the trigger is still pressed by a user after the pressure chamber has been completed, the liquid pressed by the piston is put back into the bottle through a flow hole 910 which is placed on the right in the normal lower position (pressure spring with maximum compression) of the pressure piston in the pressure chamber. Thus, if the pressure spring is pushed downwards, the pressure piston will temporarily drip below the flow orifice and additional liquid will be pressed into the pressure chamber then returning to the container due to the flow, as shown on the right side of Figure 9. This it is a safe feature to prevent overcompression and compromise of the pressure spring 365. Additionally, any slight overcompression of air between the containers can be pressed between the two layers of the container as shown by the arrows shown in blue at the bottom of the right image of Figure 9 In the situation in Figure 9 when the pressure piston rises to cover the flow hole 910, the liquid in the pressure chamber is now under pressure from the pressure spring under the pressure piston. In this configuration, the liquid will not be able to return in the bottle when it is closed by the inlet valve part of the dome valve. Similarly, the liquid cannot yet pass through the outlet channel and through the orifice before the activation valve is released, the transport valve is blocked and the liquid cannot pass through the nozzle or the outlet channel. User action will not be required to spray.
    [00021] Figure 10 shows the exemplary Flairosol device in Figure 3 once the user has pressed down the activation button 310 (as shown by the black arrow direction) in the left image, the membrane valve lock then released, and the spraying being initiated according to exemplary configurations of the present invention. When the activation button 301 is pressed, the transport valve will be unlocked. As a result, the only barrier to the liquid outlet will be to start at minimal pressure to overcome the membrane valve (and, if implemented, an extra spring behind the transport valve as shown in Figure 4). Thus, the liquid deforms the membrane valve (exceeding its opening pressure) and pressing the transport valve backwards, and thus the liquid passing through the outlet channel 390 towards the nozzle, as shown in Figure 10, and in particular, the right image of Figure 10. As noted, the opening pressure in combination with the membrane valve + transport valve can be increased by the diction or additional spring as shown in Figure 4, for example, or by increasing the opening pressure of these structures, as it may be necessary for high pressure applications, such as viscous liquids or fine spray mixture, as noted above (the highest liquid pressure, the finest mixture). Figure 11 illustrates a user stopping spraying according to exemplary configurations of the present invention. To prevent dripping, the liquid must be closed very suddenly. Thus, if the pressure of the liquid is too low to create a good spray, the membrane valve deforms to its original state and blocks the liquid. Thus, the outlet valve immediately closes when the activation button 310 is released by the user, as shown on the left side of Figure 11. Alternatively, even if not released, when the liquid pressure in the central vertical channel is too low to open the outlet valve, for example, if the user has left the entire pressure chamber empty, as shown on the right side of Figure 11. In general, the opening pressure of the dome valve or equivalent that opens the entrance of the central vertical channel in the valve body it will be higher than (i) the opening pressure of the outlet channel valve or the transport valve, and also higher than (ii) the maximum pressure developed in the pressure chamber (in the lowest position of the pressure piston) , corresponding to the force F2 released by the pressure spring. This keeps the liquid pressurized within the central channel and the pressure chamber while not being sprayed. as for (i) the opening pressure of the dome valve (or another pressure chamber; inlet valve of the central channel); (ii) maximum pressure of the pressure spring in its lowest part allowed position; and (iii) opening pressure of the membrane valve + transport valve (or other top outlet valve) can be used in several exemplary configurations of the present invention depending on the particular application, the viscosity of the liquid to be dispensed, the desired volume of the chamber pressure and also the desired length of the spray time, the desired outlet pressure and the fineness of the mixture or spray, etc. There are many variables that can then be used to release a wide group of devices for various commercial products and desired applications. B. Continuous Spray Flairosol
    [00022] Figures 12-18 represent continuous Flairosol spray according to exemplary configurations of the present invention, described below.
    [00023] Figure 12 shows an exemplary continuous Flairosol spray device on the outer side. It should be noted that there is only one trigger for the user to pump, but no activation button (compared to Figure 2, images on the left side of Figure 1).
    [00024] Figure 13 is analogous to Figure 3, discussed above. Figure 3 represents the main principle of the same for both Flairosol systems, that is, the activation button and continuous spray. The main differences between the two configurations are, as noted, that no activation button will be required for the Flairosol continuous spray version. It should also be noted that an outlet valve will obviously be required in both versions, such as the 1320 diaphragm valve in Figure 13, but that in the continuous spray configuration the drip or the transport valve that can be blocked before the pressure chamber will not cease be emptied. If the pressure of the pressurized liquid is high enough, as described below, a membrane valve, or another valve, such as a spring loaded valve, at the top of the central vertical channel opens and the liquid will pass through the outlet channel . Additionally, for the continuous spray version, the pressure chamber can be made smaller, for example, so that once the user stops pumping the trigger a defined and controlled amount of the liquid will be vaporized from the bottle.
    [00025] It was then shown in Figure 13, the membrane valve 1320, the piston chamber 1335, the piston 1330, the central vertical channel 1325, the dome valve 1370 and the outlet tube 1380. In the exemplary configurations of the present invention, piston 1330 can be activated, for example, by the trigger or lever 1350, which itself can be connected to piston 1330, for example, by a pivot arm anchored in a point, or any other suitable mechanism. Said operation of the trigger or lever 1350 pressurizes a part of the liquid, in the same way as described above for the Flairosol activation button version.
    [00026] Figure 14 analogous to Figure 4 shows how an additional 1390 spring or other reinforcing device can be added to the 1340 dome valve.
    [00027] Figure 15 represents an exemplary impulse to release this exemplary continuous spray configuration. With reference to the same, when the trigger 1350, which can, for example, be loaded with a spring, using an integrated plastic spring, moves forward, the liquid being sucked into the piston chamber, as described above in connection with Figure 5 In addition, as shown in the left panel of Figure 15, the bottom of the Flair® bottle container is ventilated, so that air can be sucked between the two layers of the Flair® bottle when underpressure is developed in the container internal due to liquid being withdrawn in the piston chamber. In this initial release impulse, both pressure chamber 1370 and central vertical channel 1325 will have no liquid in them.
    [00028] In Figure 16, a subsequent compression pulse is shown. Here, when the user presses the trigger 1350 downwards, the liquid will be pressed out of the piston chamber 1335 and will normally pass close to the dome valve 1340, which opens, and through the new open orifice (in which the dome valve 1340 is normally seated) upwards in the central vertical channel 1325 and downwards in the pressure chamber 1370. When the liquid enters the pressure chamber 1370, the pressure spring 1365, under the pressure piston 1360, is compressed as shown in 1610 The liquid inside the piston chamber is pressed past the dome valve in the pressure chamber, as noted, and from the central vertical channel 1325 past membrane valve 1320 to outlet channel 1390 and the nozzle, as shown in 1620, does not with the activation button interaction necessary to enable the flow flow. Spraying will continue until the pressure chamber is emptied.
    [00029] Figure 17 shows a subsequent release pulse, during which the now pressurized liquid inside the central channel 1325 (above the pressure chamber 1370) is still pressed out through the nozzle, as described above. During this consecutive release impulse, the liquid is pressed out of the pressure chamber through the orifice and the liquid is still sucked into the piston chamber 1335 when the trigger moves externally and the piston chamber is filled with liquid from the container, as described above. In this way, the user can maintain the spraying by performing fewer impulses, as described below, if the inlet volume is properly established in relation to the outlet volume, a continuous spray can be maintained as long as the user wishes.
    [00030] In the exemplary configurations of the present invention, by designating the piston chamber volume to be greater than that of the pressure chamber, the user will be able to keep the Flairosol device spraying while making only a few impulses, as each pumping impulse being more than enough to refill the pressure chamber, and thus having high pressure in the pressure chamber to spray. When the user stops making pumping impulses with the trigger, the membrane valve closes as well as the pressure drips, due to the pre-compression property of this valve. This prevents dripping and ensures that when the liquid is sprayed it will have a minimum velocity and thus a relatively close distribution of velocities for all particles sprayed, as in the case of all pre-compression systems.
    [00031] As noted, for a given nozzle size and through it, by adjusting the size of the pressure chamber relative to the size of the piston chamber, the vaporizer outlet rate may be set to be less than the inlet rate. This ensures that as long as the user keeps pumping the trigger, the vaporizer will continue to spray. For example, if the output is set at 0.7 cc per second (this is a function of, inter alia, the nozzle diameter and swirl chamber length, etc.) and the input being set at 1.6 cc per pulse (chamber volume piston), a user who pushes an impulse every 2.2 seconds, will always be “in front” of the spray outlet, and does not need rapid movement to keep the pressure chamber filled. Various volumes and relative volumes of the piston chamber and the pressure chamber may be used that may be appropriate for a particular application and context.
    [00032] Alternatively, for example, if the application is one that a semi-continuous spray is desired, where you are sure you want to keep spraying, when using very expensive or very dangerous liquids, the reverse can be implemented, and the entrance can be established to be less than the output volume. In this case, the inlet will always be "behind" the outlet, and the user will have to intentionally keep pumping in order to keep the pressure chamber filled.
    [00033] Additionally, it should be understood that once the user stops the trigger pumping, the spray continues until the pressure chamber is completely empty, or potential energy in the spring under the pressure piston has dissipated when the pressure in the pressure chamber is less than the pressure of the outlet valve opening. So at a certain flow rate, and a certain size of the pressure chamber, the Flairosol sprayer will continue to spray for some time. This can be adjusted to be longer or shorter depending on the application, by adjusting the relative piston chamber and pressure chamber sizes, as noted, for a constant nozzle outlet. As will be appreciated, Flairosol technology discreetly converts the input pump impulse to a continuous spray, using a liquid plug - the pressure chamber. By properly adjusting the relative volumes, as noted, the continuous spray can be maintained with relatively small pumping impulses, and they will not need to be evenly spaced at all, determined by the liquid cap (ie the pressure chamber plus the central vertical channel ). This makes the substitute use of aerosols easy and clean, and providing the contents due to the Flair® inner container / outlet technology that never contacts the outside air in or around it, thus being free from contamination and remaining fresh.
    [00034] It should be noted that in the exemplary configurations of the present invention, due to the use of Flair® technology in Flairosol, the inner bottle will always be compressed by ambient pressure (or other means of displacement) in order to reduce the sprayed liquid throughout the time. As with the Flair technology, any liquid remains in the inner bottle and is always viable to be removed by the piston in the piston chamber and then sent to the pressure chamber. No air pockets or cracks will be developed in the internal Flair® bottle, with no need to attach below the internal container at the bottom of the device to prevent crimping or pinning. As with all Flair technology, any liquid that remains in the inner bottle is always viable to be removed by the piston in the piston chamber and sent to the pressure chamber. No air pockets or cracks will be developed in the Flair® internal bottle, there is no need to tie it below the internal container at the bottom of the device to prevent stamping or pinning. Thus, the effectiveness of combining Flair® technology with the spraying of a clean or “green” pressurized liquid similar to an areosol, in the various configurations of the present invention.
