    BOTTLE and METHOD OF SUPPLYING A SYSTEM TO DISPENSE AN AEROSOL COMPOSITION. It is a thermoplastic bottle (100) that has a crimped valve cup (204) and a method of manufacturing a thermoplastic bottle (100) that includes crimping a valve cup (204) to such a bottle. The thermoplastic bottle (100) and the valve cup (204) can be used in a system for dispensing aerosol products. At least one protuberance extends from a flange of the bottle (100) in which the valve cup (204) is crimped. Before being crimped on the bottle (100), the valve cup (204) is installed on the bottle (100) with an interference fit between a crease portion of the valve cup (204) and the protrusion (114). The interference fit prevents the valve cup (204) from moving from its position installed on the bottle (100) before the valve cup (204) is crimped.

    Field of the Invention
    [001] The present invention relates generally to a thermoplastic bottle on which a structure is crimped and a method of manufacturing a thermoplastic bottle which includes crimping a structure on the bottle. More specifically, the present invention relates to a thermoplastic bottle that includes protuberances that extend from a flange adjacent to one end of the bottle, with the protuberances providing an interference fit with a valve cup before valve cup to be pleated on the flange. Related Technique
    [002] Systems that are used to dispense liquid and / or gaseous products from a container such as a bottle and, in particular, in systems that are used to dispense aerosol products, a valve mechanism is used to allow the selected product release from the bottle. The valve mechanism is usually a separately fabricated structure that is attached to the bottle after the bottle structure itself is manufactured. Often, the valve structure includes a valve cup as the portion that is physically attached to the bottle, with the valve cup positioned adjacent an open end of the bottle. An example of such a valve cup can be seen in US Patent 4,730,752, which is incorporated herein in its entirety for reference.
    [003] To attach a valve cup to a bottle, the valve cup can be crimped onto a portion of the bottle such as an annular ring which is provided adjacent to an open end of the bottle. The aforementioned US4,730,752 patent demonstrates the fold of a valve cup in a bottle. Pleat fixation of a valve cup is usually performed in a two-step process. First, the valve cup is installed over the bottle at a location on a manufacturing line. The installed bottle and valve cup are then moved to a pleating station at another location on the manufacturing line, where the valve cup is crimped onto the bottle frame.
    [004] Due to the fact that the installation of the valve cup on the bottle and the fold of the valve cup on the bottle are separate steps, and due to the fact that the bottle with the valve cup installed, but not crimped, is often moved before the pleat operation, a problem sometimes arises in which the valve cup may move from its initially installed position before the pleat operation occurs. In general, the tolerance in the positioning of the valve cup that allows for a successful pleating operation is very small, sometimes in the order of thousandths of an inch. Thus, even a small displacement in the valve cup can considerably reduce the effectiveness of the crimp connection between the valve cup and the bottle. For aerosol products, when the bottle with an ineffectively crimped valve cup is pressurized, the valve cup can sometimes be completely blown out of the bottle. In less extreme examples, poorly pleated valve cups can allow product to leak out of the bottle.
    [005] To stabilize a valve cup installed, but not crimped, in a bottle, cavities are sometimes added to the portion of the valve cup that comes in contact with the bottle. The cavities can effectively hold the valve cup in place prior to the pleating operation, particularly when the bottle is produced from a metallic material. In addition, the cavities do not damage the relatively strong metallic structure of the bottle when the valve cup is crimped.
    [006] There is growing interest, however, in the use of thermoplastic bottles that dispense aerosol products. Compared to metal bottles, thermoplastic bottles provide greater flexibility in terms of manufacturing and aesthetic design, recyclability, and thermoplastic bottles are potentially less expensive than metal bottles. When a valve cup that includes cavities in its crease portion is pleated in a thermoplastic bottle, the cavities create high tension in the portions of the plastic structure of the bottle that are counted by the cavities after the crease. The tension created by the cavities can sometimes crack the structure of the thermoplastic bottle, rendering the thermoplastic bottle useless for dispensing pressurized products, such as aerosol compositions. SUMMARY OF THE INVENTION
    [007] One aspect of the present invention provides a bottle. The bottle includes a main body with an open end and a closed end. A flange is positioned adjacent to the open end, with the flange being configured to contact and secure a structure that is crimped on the flange in such a way as to close the open end of the bottle. At least one protuberance extends from the flange in a direction contrary to the rest of the bottle. The main body, the annular flange and at least one protuberance are formed from a thermoplastic material.
    [008] Another aspect of the present invention is to provide a method of providing a system that dispenses an aerosol composition. The method includes installing a structure adjacent to a flange at one end of the bottle, with an interference fit being provided between the structure and the bottle. The valve cup is crimped onto the flange of the bottle and an aerosol composition is provided in the bottle. The bottle is produced from a thermo-plastic material.
    [009] According to another aspect, the present invention provides a method for crimping a structure in a bottle. The method includes providing a bottle formed from a thermoplastic material. A frame is installed adjacent to a bottle opening at a first location, with the frame being installed on the bottle with an interference fit. The bottle and the installed structure are moved from the first location to a second location, and the structure is crimped on the bottle at the second location. BRIEF DESCRIPTION OF THE DRAWINGS

    [020] The present invention relates to the folding of a structure in a thermoplastic bottle.
    [021] In specific embodiments, the present invention relates to folding the valve cup portion of a valve structure into a thermoplastic bottle as part of a process for creating a system for dispensing a liquid product and / or a gaseous. Specific products that could be dispensed using the system include aerosol spray compositions, such as air fresheners, carpet cleaners, insect repellents, deodorants, hair sprays, cleansing preparations and shaving preparations, including foams and gels. Other examples of products that can be dispensed using the system include fabric perfumers, cooling agents, deodorants, sanitizers, disinfectants, soaps, insecticides, fertilizers, herbicides, fungicides, algae, pesticides, extermination agents rodents, paints, body sprays, topical sprays, polishes and footwear and shoe products. The system, however, is not limited to the dispensing of any particular type of spray, nor is the system limited to the dispensing of any particular type of product.
    [022] A propellant gas is used to dispense aerosol and other products. In general, there are two main types of propellants used in aerosol systems: (1) liquefied propellant gases and (2) compressed propellant gases, such as carbon dioxide and nitrogen. Each of these types of propellant can be used with the system described in the present invention. The particular type of liquefied gas or compressed gas that is used as the propellant in the system can be selected based on convenience, cost, properties of the corresponding container, properties of the liquid product formulation, etc. Examples of known liquefied propellant gases that can be used with the system include hydrocarbons and hydrofluorocarbons (HFCs). Examples of known compressed gases that can be used in a system according to the invention include air, argon, nitrogen, nitrous oxide, inert gases and carbon dioxide.
    [023] Along with the particular type of propellant gas, the amount of upper space provided by the gas can be adjusted or customized as desired. When using a compressed propellant gas, the compressed gas does not significantly dissolve in the liquid portion of the product, but preferably the amount of head space is primarily a function of the amount of compressed gas used in the container. In exemplary embodiments of systems according to the invention, a space greater than 30 to 40% is used. However, in alternative modalities, the upper space could be less than 30% or greater than 40%.
    [024] Along these lines, an element of common knowledge in the art will appreciate that the properties of such compressed gas products, including viscosity, density and surface tension, can be easily adjusted to achieve the desired effects. In exemplary embodiments, the density of the compressed gas product is about 1.00 g / cm, the surface tension is about 30 mN / m and the viscosity is about 1.0 to 1.6 cP.
    [025] A liquid component used in the inventive system will include the type of composition to be dispensed, for example, an air-perfuming composition. In some embodiments, the liquid component will include at least 90% water and less than 10% low molecular weight alcohols. In a more specific embodiment, the composition includes less than 4% low molecular weight alcohols. The liquid component could also include additional compositions, such as surfactants and / or solvents to facilitate the dissolution of the liquid component with another liquid component.
    [026] Figure 1 shows a plastic dispensing bottle 100 according to an embodiment of the invention. Plastic bottle 100 includes an open end 102, a main body portion 104 and closed end 106. The product to be dispensed is contained inside 108 of bottle 100. It should be noted that a bottle according to the invention is not limited to particular shape or configuration which is shown in Figure 1. For example, the main body portion 104 of the bottle 100 could be more or less cylindrically shaped than revealed. Alternatively, the main body portion 104 could have multiple sides in order to have a multi-sided polygon in cross section. Additionally, although not shown, the surface of the main body 104 could be formed with desired characteristics, such as shoulders, ridges, etc. In addition, the open and closed ends 102 and 106 could be formed in any desired shape.
    [027] Bottle 100 is produced from a thermoplastic material. Examples of thermoplastic materials that could be used to form bottle 100 include ethylene-based polymers, such as ethylene / vinyl acetate, ethylene acrylate, ethylene methacrylate, ethylene methylacrylate, methylene methacrylate, acetate carbon monoxide ethylene vinyl chloride and N-butyl ethyl acrylate carbon monoxide, polybutene-1, high and low density polyethylene, mixtures of chemically modified polyethylene and polyethylene, ethylene copolymers and mono- or di-unsaturated monomers C1 to C6, polyamides , polybutadiene rubber, polyesters such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate; thermoplastic polycarbonates, non-toxic polyalphaolefins, including non-toxic polypropylene, polyvinylmethyl ether and others; thermoplastic polyacrylamides, polyacrylonitrile, acrylonitrile copolymers and other monomers such as styrene butadiene; polymethyl pentene, polyphenylene sulfide, aromatic polyurethanes; styrene-acrylonitrile, acrylonitrile-butadiene-styrene, styrene-butadiene rubbers, acrylonitrile-butadiene-styrene elastomers, polyphenylene sulfide, block polymers AB, ABA, A- (BA) nB, (AB) nY, em whereas block A comprises an aromatic polyvinyl block such as polystyrene, block B comprises an intermediate rubber block which may be polyisoprene and, optionally, hydrogenated, such as polybutadiene, Y comprises a multivalent compound, and n is an integer at least three, and mixtures of these substances. In particular embodiments, the thermoplastic material is polyethylene terephthalate (PET). PET is a readily available thermoplastic that is sold by many different manufacturers. Along these lines, the thermoplastic polymer used to produce the plastic bottle 100 can be transparent, opaque or partially opaque.
    [028] The plastic bottle 100 can be formed by a variety of techniques that are known in the art. As an example, plastic bottle 100 can be formed using an injection molding process in combination with a blow molding process. In this example, a plastic bottle 100 preform is first made using injection molding techniques. The preform provides the mass of material that is eventually sketched into the final shape of bottle 100. The preform can also include portions of the bottle in a substantially final shape. For example, in bottle 100, an annular flange 110 and an annular ring 111 in a neck portion of bottle 100 may be present in the preform and not altered thereafter. It is noted that the ring rim 111 can be supplied to the bottle 100 in order to facilitate the handling of the bottle during the forming processes. The bottle preform is subsequently blow molded to reveal portions of the thermoplastic material in the shape of the final bottle. The blow molding process includes heating the preform, wrapping the preform within a blow molded structure and expanding the heated preform into the shape of the mold using air pressure. Using the combination of a blow and injection molding process, the plastic bottle 100 can be formed integrally, with a one-piece construction.
    [029] Those skilled in the art will recognize the various alternative techniques that can be used to produce a thermoplastic bottle according to the invention, including different injection and blow molding techniques from those described above. Similarly, those skilled in the art will recognize that a thermoplastic bottle, as described in the present invention, does not need to be formed as an integral structure, but can be formed by processes in which the portions of the bottle are separately manufactured, with the separate portions connected in order to form the final structure of the claw.
    [030] Plastic bottle 100 can be used to contain and dispense pressurized products, such as mixtures of gas and liquid that form aerosol sprays. In this regard, the plastic bottle 100 can be made in accordance with applicable regulations to produce pressurized dispensing products, such as the Department of Transport regulations (DOT) and the regulations of the Interstate Commerce Commission (ICC) of the USA. Such regulations determine certain dimensional, material, manufacturing, wall thickness and test requirements for a container to be loaded at a given pressure.
    [031] Figures 2A to 2C are detailed views of the open end of the bottle 100. The annular flange 110 is provided adjacent to the open end 102 of the bottle 100. A structure, such as a valve cup, can be crimped on the flange annu home 110, as will be described in detail below. The annular flange 110 includes a plurality of protrusions 114 that extend outwardly from the surface of the annular flange 110. The protrusions 114 provide an interference fit with the structure to be crimped over a period of time when the structure is installed in the bottle 100, but not yet crimped on the annular flange 110, as described in detail below.
    [032] It should be noted that, although the flange 110 shown in Figures 2A to 2C is annular, that is, substantially ring-shaped, in other embodiments, the flange 110 may have a different shape and positioning. For example, flange 110 could have multiple sides in some embodiments and flange 110 could be installed back at the top end of bottle 100 towards ring rim 111. In this regard, those skilled in the art will recognize that flange 110 it can be configured in a way that corresponds to the shape of the portion of the bottle from which the flange extends. Additionally or alternatively, the flange 110 can be configured in a manner that allows for easy formation of the flange 110 in the manufacturing process bottle, for example, the flange 110 can be configured to allow its molding in combination with the rest of the bottle 100.
    [033] In some embodiments, the protrusions 114 are integrally supplied with the annular flange. For example, protuberances 114 can be integrally molded in the two-stage blow molding process described above. In alternative embodiments, the protrusions may be separately provided on the flange 110, for example, by an impression-type operation.
    [034] The protrusions 114 can vary in size, shape and position on the flange 110. Regarding the shape, the protrusions 114 can be, for example, round, square, rectangular, hexagonal, triangular, diamond-shaped, oval , pyramidal or any other format. In relation to sizing, in some modalities, if protuberances 114 extend from about 0.02 mm to about 2 mm from the annular flange 110, in more specific modalities, protuberances 114 extend from about from 0.02 mm to about 0.5 mm from the annular flange 110 and, in even more specific embodiments, the protuberances 114 extend from about 0.02 mm to about 0.3 mm from the annular flange 110. In a particular embodiment, protrusions 114 extend about 0.1 mm from flange 110. In general, the larger protrusions 114, the greater the cross-sectional area provided by each of protrusions 114 and the greater the number of protuberances 114 extending from flange 110, the greater the interference fit that will be created with a structure installed on flange 110, as will be described in greater detail below. The protrusions 114 can also be configured to assist in centering the structure installed on the flange to crimp.
    [035] Notably, there is no requirement for all protuberances 114 in bottle 100 to have the same size, shape or extend the same distance from flange 110 of bottle 100.
    [036] As generically indicated in Figures 1 and 2A to 2C, the protuberances 114 extend in a direction that is substantially orthogonal to a geometric axis of the bottle that runs from the open end 102 to the closed end 106. In other embodiments, the protuberances 114 can be installed at angles not perpendicular to the geometric axis of the bottle. As with the size, shape and position of the protrusions 114, the angle at which the protrusions 114 are installed can be varied in order to adjust the interference fit created with the protrusions, as will be described below.
    [037] In the form of the bottle 100 which is revealed in Figures 2A-2C, the three-protuberance patterns 114 are provided on opposite sides of the flange 112.
    [038] Additionally, single protrusions 115 are provided in positions on opposite sides of flange 112. The revealed 3/1/3/1 pattern of protrusions 114, however, is merely an example of a pattern that can be used in modalida -des of the invention. In other embodiments, different protrusion patterns can be used. Figure 3 demonstrates such an alternative pattern of protuberances 114a. In this embodiment, the protrusions 114a are installed around one hundred and twenty degrees apart on the annular flange 110. Notably, in the modalities shown in Figures 2A to 2C and 3, the protrusions 114, 114a and 115 are positioned symmetrically around the flange annul 110. However, protuberances 114, 114a and 115 are not required to be arranged symmetrically and, in other modes, the protuberances are provided asymmetrically around the flange of the bottle. It will be further appreciated from the above and from the following descriptions, that in some modalities only a single protuberance can be provided on the annular flange.
    [039] That is, a single protuberance can be configured with a size and shape to provide the desired interference fit between the uncrimped pleated valve cup and the bottle described below.
    [040] Figure 4 reveals the bottle 100 with a valve structure 200 that closes the open end of the bottle 100. The valve structure 200 includes a valve shaft 202 through which the product contained inside 108 of the bottle 100 is provided. -thought. The valve structure 200 also includes a valve cup 204 which is crimped on the annular flange 110 of the bottle 100, as will be described in greater detail below. The valve cup 204, in fact, provides a lid for closing the open end 102 of the bottle 100. In this regard, although a "valve cup" is described and disclosed in the present document as being a structure that is crimped on the open end of the bottle, the structure that is crimped on the bottle can alternatively be of numerous other shapes, such as a cap, overcap, cover, etc. And, in many embodiments, the crimped structure will be formed to substantially close the open end of the bottle. The only requirement for the structure that is crimped on the bottle is that the structure has a pleat portion that can be brought into contact with the bottle in the same way as the pleat portion of the valve cup described below.
    [041] Additional details of valve structure 200 can be seen in Figure 5, including valve seat 208, immersion tube 210 and valve cup gasket 212. Note that valve cup 202 it is a stand-alone structure of other components of valve structure 200. As such, valve cup 204 can be installed and crimped on bottle 100 before the other components of valve structure 200 that are assembled with the bottle .
    [042] Although a specific valve structure 200 is disclosed, those skilled in the art will recognize that there are a wide variety of alternative valve structures that can be used in conjunction with the invention described in the present invention. Examples of such valve structures can be found, for example, in US Patent Nos. 5,503,303; 6,817,493; 6,820,823; 7,028,866, 7,303,087; and US design patent No. 587,576, and publication of US patent application No. 2009/0020621, all of which are incorporated by reference in their entirety. It should be noted that components of valve structure 200 can be produced from a variety of materials, including, for example, the thermoplastics that are described above as being capable of being used to form bottle 100. As an alternative, some or all components of valve structure 200 can be produced from metallic materials, such as steel, tin-free steel, aluminum, etc.
    [043] Figures 6A and 6B reveal the valve cup 204 installed adjacent to the annular flange 110 before a pleating operation, and Figure 7 reveals the valve cup 204 after being crimped on the annular flange 110. As shown in Figure 6B , the protrusions 114 extend from the annular flange 110 for the purpose of coming into contact with the pleat portion 206 of the valve cup 204. The interference fit created by the protrusions 114 that come into contact with the pleat portion 206 ensures the positioning of the valve cup 200 on the bottle 100 in such a way that the valve cup 204 will not move or move before being crimped onto the annular flange 110. Thus, the installed valve cup 204 is more likely to be in position needed for a successful pleat operation.
    [044] The term "interference fit", as used in the present invention, means a closure between two parts, for example, between the valve cup and the protuberances on the annular flange of the bottle, which is reached by the friction after the parts to be pushed into the slot In some embodiments, an interference fit according to the invention is achieved having about 0.1 mm to about 0.2 mm overlap between the protrusions 114 and the pleat portion 206 valve cup 204. For example, with a circular annular flange 110, protrusions 114 extend from annular flange 110 to points that define a diameter of bottle 100 that is about 0.1 mm to about 0 , 2 mm larger than the diameter of the pleat portion 206 of the valve cup 204.
    [045] Figure 7 reveals the valve cup 204 after being crimped on the annular flange 110 of the bottle 100. After the pleat, the pleat portion 206 of the valve cup 204 is folded around and under the annular flange 110. This pleat of the valve cup 204 on the annular flange 110 of the bottle 100 provides a secure fixation such that the valve body 204 will remain in place when the bottle 100 is filled with product. For example, when filled with an aerosol product as described above, the crimped valve cup 204 will remain in place against the internal pressure of the bottle. It should be noted, however, that, in alternative modes, the pleat portion 206 could be less extended in relation to the flange 110 than shown in Figure 7. That is, the pleat portion 206 could be shortened with the purpose of crimping the sides of the annular flange 110, but not extending around the underside of the annular flange 110 when crimped.
    [046] As discussed above, the components of valve structure 200, including valve cup 204 with pleat portion 206, can be formed from plastic materials or metallic materials. In some embodiments, the material used to form valve cup 202 is selected based on the configuration and structure of protrusions 114. For example, if protrusions 114 are produced from a thermoplastic material that is more malleable / flexible, or the protrusions 114 extend in the lower range of the distances described above, the pleat portion 206 of the valve cup 204 can be formed from a more rigid material, such as a rigid metallic material. As another example, if the protrusions 114 are produced from a thermoplastic material that is less malleable / flexible or the protrusions 114 extend in the upper range of the distances described above, the pleat portion 206 of the valve cup 204 can be produced from malleable / flexible materials. With such examples, the interference fit can be formed between the protrusions 114 and the fold portions 206 while still allowing malleability / flexibility in the contact structures in such a way that there is little damage from the bottle cracking according to the structures contact points are placed together in the socket with interference.
    [047] Valve cup 202 disclosed in Figures 6A, 6B and 7 is commonly called "externally crimped" as the pleat portion 206 of valve cup 202 extends over an outer portion (annular flange 110 ) of the bottle 100. In alternative embodiments, a bottle and the valve cup according to the invention can be supplied in such a way that the valve cup is internally crimped on the bottle, that is, the pleat portion of the valve is crimped on the inside the bottle. In such embodiments, the protrusions provided on the bottle extend from a surface inside the bottle on which the valve is crimped. In such embodiments, an interference fit between the protrusions and the internally crimped valve cup is created in the same way as the externally crimped valve cup.
    [048] A manufacturing process for providing a system for dispensing an aerosol composition will now be described. In the inventive manufacturing process, a bottle, as described above, is initially supplied. That is, a bottle is formed from a thermoplastic material using, for example, the injection molding process and the blow molding process described above. The molded thermoplastic bottle includes an open end and a closed end and an annular flange with protrusions is provided adjacent the open end of the bottle.
    [049] The bottle is positioned on the manufacturing line at a station where a valve cup is installed at the open end of the bottle. As described above, the valve cup is dimensioned and configured in such a way that an interference fit is achieved between a crease portion of the valve cup and the protrusions on the flange of the bottle. The bottle is then moved to a second location where the valve cup is crimped on the annular flange. For these operations, any form of installation and pleat devices can be used, which have the ability to position the valve cup on the bottle and press the valve cup on the flange of the bottle in the pleat operation. Such devices are known in the art. Additionally, it is observed again that in alternative modalities, structures in addition to a valve cup can be installed and crimped on the bottle. In such embodiments, the same types of manufacturing processes and devices can be used.
    [050] Because of the interference fit between the pleat portion of the valve cup and the protrusions extending from the flange of the bottle, the valve cup does not move easily from the position installed before the valve cup. valve to be crimped in the bottle. In this way, even when the valve cup needs to be precisely installed in the bottle to secure the valve cup pleat, the bottle with the valve cup installed can still be moved to a location on the manufacturing line for the pleat operation. In addition, due to the fact that the lumps are part of the bottle structure, the provision of the lumps does not create any high stress areas in the bottle structure after the valve cup is crimped onto the bottle.
    [051] The manufacturing process can also include the steps of filling the bottle with the product. In specific embodiments, these steps include pre-filling the bottle with an aerosol composition in such a way that the bottle becomes pressurized. Along these lines, the manufacturing process can also include the steps of supplying valve structure components in the bottle in addition to the valve cup. Those skilled in the art will recognize various techniques for performing such steps. In addition, those skilled in the art will recognize that such steps can be preformed in different orders in different processes.
    [052] As yet an example of another alternative process according to the invention, a structure can be positioned on the bottle at a location on a manufacturing process line and the structure can be crimped on the bottle at the same location. That is, a mechanism can be provided that installs the structure on the bottle in one location, and then a pleat mechanism can be placed in place to crimp the structure on the bottle. In this case, the interference fit created by the protrusions in the bottle and in the crease portion of the structure prevents the structure from moving, which can still occur despite the fact that the bottle is in the same position during installation and pleating operations.
    [053] Although this invention has been described in certain specific exemplary embodiments, many additional modifications and variations would be evident for those skilled in the art in light of this disclosure. Therefore, it is understood that this invention can be put into practice in a way other than specifically described. Thus, the exemplary modalities of the invention must be considered in all respects as being illustrative and not restrictive, and the scope of the invention as being determined by any of the claims supported by this application and the equivalents thereof, in instead of the previously mentioned description. Industrial Applicability
    [054] The invention described in this document can be used to produce a wide variety of commercial products, including systems for dispensing aerosol compositions such as air fresheners, carpet cleaners, insect repellents, deodorants, hair sprays and preparations. cleaning. As such, the inventive devices, systems and methods described in this document are applicable in various industries.
