Definitions

  • An aerosol valve assembly has a valve which is pressure biased to a normally closed position, the valve being opened by an operator actuated by the application of manual force, and the assembly including a means for applying a resistance to movement of the valve when the operator receives an initial application of manual force and which releases said resistance with an increase in this force so that this increased force causes the valve to open with a snap action.
  • valves which are applied to containers which are internally pressurized and contain one or more fluids to be dispensed, whether the fluid or fluids are dispensed in the form of an aerosol spray, a foam, as a solid stream of liquid or liquids, or in any other form.
  • a valve of this kind has a projecting stem acting as an operator and adopted to be manually actuated by finger pressure to open the valve and dispense the product or products in the container.
  • This stem may be directly actuated but is more often provided with a small handle which may also act as a nozzle.
  • finger pressure applying too little force to obtain complete opening, the result being an improper discharge of the product in the container, which is, of course, undesirable even if it occurs only initially followed by a full discharge resulting from increased finger pressure.
  • valves of the co-dispensing type are required.
  • hair coloring requires the packaging of a liquid containing coloring and, if desired, a foaming agent, and also a liquid such as a peroxide solution, and these two components must be intermixed and dispensed simultaneously.
  • the valve which dispenses the two components ordinarily called a co-dispensing valve, should not permit any material amount of the intermixed components to remain in the valve construction after the valve is closed, because of their incompatible nature.
  • Prior art codispensing valves have in one form comprised two ports supplied with the two components and which should be simultaneously opened and closed by depression of a valve in a linear fashion by the use of finger pressure.
  • the valve operator since the valve operator is finger actuated, it has been possible to apply an angular motion resulting in erratic and non-uniform dispensing of the two components.
  • proper proportioning of the two components can be obtained only when the valve is fully opened so that the two ports are unobstructed; but it is possible to only partially open prior art codispensing valves, this again resulting in improper proportioning of the components.
  • Aerosol dispensing valves of both the single and codispensing types have at times experienced sealing difficulties. This, of course, results in an unsatisfactorily short shelf life, resulting in customer dissatisfaction.
  • an object of the present invention is to produce a simple valve using the fewest possible parts in its construction which provides substantial assurance against partial opening by the appli cation of finger pressure to the valve operator, and which in the case of the co-dispensing type of valve more positively assures the components proper proportioning and without entrapping mixed components upon closing of the valve, while as to all types of such valves, providing better assurance against leakage when not in operation.
  • Another object in addition to using a minimum of parts in the valve construction, is to permit elimination of the use of metal parts of any kind, in view of the fact that some components packaged in pressurized containers tend to be corrosive to metals of any kind that can be economically used in manufacturing the valves.
  • FIG. 1 is a perspective view of a pressurized container of the type containing two products to be dispensed simultaneously and indicating schematically to some extent the manner in which the products are packaged within the container;
  • FIG. 2 is a vertical section of an example of a codispensing valve embodying some of the features of the present invention, the valve being in its normally closed position;
  • FIG. 3 is the same as FIG. 2, but shows the valve in its opened position
  • FIG. 4 is a cross section taken on the line 4-4 in FIG. 2;
  • FIG. 5 is a vertical section of a single product dispensing valve incorporating the snap action feature of the present invention.
  • FIG. 5a is a cross section taken on the line Sa-Sa in FIG. 5;
  • FIG. 6 is a vertical section of a co-dispensing valve showing a modification
  • FIG. 7 is a perspective view of the valve or valve head shown by FIG. 6;
  • FIG. 8 is a vertical section of another modification.
  • FIG. 9 is a perspective of the valve head shown by FIG. 8.
  • FIG. 1 shows the general organization of an aerosol co-dispensing package.
  • This package comprises a can I which may possibly be internally treated if necessary and adapted to confine fluid under pressure and having a co-dispensing valve 2 mounted in its top, this valve having an upwardly projecting stem 3 forming an operator adapted to be actuated by the application of manual force, such as by finger pressure, to open the valve 2, the latter being normally closed.
  • the bottom of the valve 2 has two downwardly extending nipples 4 and 5.
  • a flexible fluid impervious container 6 is connected to the nipple 4.
  • the can contains a fluid product which may include a propellant such as any of the liquified gases or non-liquified compressed gases commonly used which convert to a gas phase or expand at room temperatures and atmospheric pressures.
  • This product applies fluid pressure to the flexible container 6 which contains a fluid product to be mixed with the first one, both products being intermixed and extruded or ejected upon opening of the valve 2 by manual force applied to the stem 3.
  • the container 6 might contain a peroxide solution and a separate flexible container (not shown) might contain the coloring, with a propellant sealed in the can between it and two flexible containers and applying extruding pressure to the latter.
  • FIGS. 2 and 3 of the drawings One example of the valve of the present invention, in co-dispensing form, is illustrated by FIGS. 2 and 3 of the drawings.
  • the valve comprises a cup-shaped body 8 having a cylindrical sidewall 9 and a bottom 10.
  • the top of the body 8 is closed by a closure 11 in the form of an elastically deformable gasket having an inner surface 12 forming a valve seat.
  • This closure or gasket may be made from material currently used for present aerosol gaskets, including soft molded plastic seals, such as low density polyethylene.
  • the valve itself has a cylindrical portion 13 slidingly fitting the cylindrical inside of the bodys sidewall 9 for vertical reciprocation between an upward position, where the valves top seats on the valve seat provided by the surface 12 ofthe closure 11 and prevents further upward movement of the valve, and a lower position forming a space 14 between the valves top and this surface or seat 12.
  • the valve also has an axially positioned tubular stem 15 extending upwardly therefrom and slidingly but substantially fluid-tightly through a hole 16 formed in the closure 11.
  • This tubular stem 15 has a hole 17 positioned to open from the space 14 into the inside of the tubular stem 15. This hole may be positioned so that when the valve is closed the hole is at least slightly below the level of the bottom of the closure or gasket 11, so any space that might remain between the top of the valve and the bottom of this closure or gasket is always vented to the outer atmosphere.
  • the cup-shaped body side wall 8 has a plurality of fluid passages extending longitudinally therethrough to ports opening into the space 14 at circumferentially spaced locations. In the case of the example being described, there are two of these passages 18 and 19, respectively having ports and 21. Extending downwardly from the cup-shaped body, are the nipples 4 and 5 suggestively illustrated in FIG. 1.
  • the passages 18 and 19 are shown as being of equal size, but they may be of unequal size or the ports 20 and 21 may be of unequal size as required for proper proportioning of the liquids or fluids to be co-dispensed in intermixed form.
  • this means comprises a conical portion 22 projecting downwardly from the bottom of the cylindrical portion 13 of the valve and an elastically deformable member 23 projecting upwardly from the inside of the cup-shaped body's bottom 10, this member embracing this conical portion 22 of the movable valve.
  • This tubular member is longitudinally slotted throughout all or most of its length, four slots 24 being shown by FIG. 4. Because the tubular member 23 is elastically deformable, its portions between the slots 24 form cantilever springs which are wedged radially or outwardly by downward depression of the stem 16 and the valve portions 13 and 22; release of this force permitting the valve to be quickly returned to its normally closed position by these springs exerting a reverse wedging action.
  • the conical portion 22 of the valve is formed with a short cylindrical section 25 at its bottom, this portion being of substantially the same outside diameter as the inside diameter of the tubular member 23 when the latter is not sprung outwardly to exert its spring action. Between this portion 25 and the conical portion 22, a rounded shoulder or bead 26 is formed.
  • the cantilever spring portions of the tubular member 23 snap beneath the shoulder 23 and embrace the cylindrical portion 25 when the valve is closed. Finger pressure, forcing the stern downwardly and which is insufficient to fully open the valve, produces no motion of the valve at all; the valve remains completely closed and, of course, closing the ports 20 and 21 completely. Increased finger pres sure causes the cantilever spring portions of the member 23 to spring suddenly outwardly and disengage from the shoulder or bead; and since this force exceeds that required to fully open the valve, the valve snaps downwardly to its fully opened position.
  • the cylindrical inside side wall 8 of the cup-shaped body, the valve portion 13, the valves conical portion 22, and the valves short cylindrical portion 25 and the tubular member 23, are all concentric parts.
  • the slots 24 provide the member 23 with diametrically opposite pressure applying springs.
  • the concentricity includes the stem 15. Therefore, when in its closed position shown by FIG. 2, the valve is prevented from rocking action, not only by the axial length of its cylindrical portion 13, but also because of the resisting portions of the tubular member 23 which are symmetrically seated on the valves bottom cylindrical portion 25 beneath the shoulder or bead 26 of the valve, this bead or shoulder being, of course, concentric with the other parts mentioned.
  • the illustrated valve of the present invention is made to comprise only two parts using plastic and injection molding techniques; the cup-shaped valve body, including the tubular longitudinally slotted member 23, being formed as one integral part.
  • the valve itself comprising its parts l3, 15, 22, 23, 25 and 26 is an integral plastic injection molding.
  • the closure or gasket 11 is used by substantially all valves of the present type and might be considered to constitute a third part. No metallic parts need be involved and it is not difficult to chose plastics which are completely compatible with all compositions which might be filled into an aerosol package.
  • closure 11 is held in position relative to the cup-shaped body 8 by the usual metallic cup member la used for attachment of the valve to a standard aerosol can.
  • the top of the cylindrical portion 13 of the valve which seats against the inside or bottom of the closure or gasket 11, may have an upwardly projecting peripheral rim 27.
  • This rim may have a sharp edge, as illustrated, which indents or seats in the valve seat provided by the inside of the elastically deformable closure or gasket 11, this occurring around the entire periphery of the rim and at the ports 20 and 21 and this closing the latter positively when the valve is in its normally closed position.
  • the rim 27 may be formed to have an outside diameter slightly greater than the inside diameter of the cup-shaped bodys cylindrical surface 9, thus providing assurance against intermixed components being forced downwardly within the cup-shaped body beneath the movable valve's bottom.
  • the bodys bottom 10 may have a port 101 formed in it, so the propellant pressure is exerted upwardly against the valve to provide an additional upward or closing force to the movable valve.
  • the snap action principle described may also be applied to a simpler dispensing valve, as is illustrated by FIG. 5, where the parts which correspond to those previously described are identified by similar numerals marked a.
  • the movable valve portion 130 provides circumferentially interspaced clearance slots between it and the inside surface 9a of the cup-shaped valve body.
  • the flat bottom of the latter has a single nipple 4a which opens through this bottom and into the inside of the longitudinally slotted tubular member 23.
  • the conical valve portion 22a is conical clear to its bottom end and is provided with a bead 280 which extends around its periphery.
  • the bead is engaged by the upper ends of the cantilever springs formed by the portions of the tubular member between its slots 240, when the valve is in its normally closed position. With enough opening force, the previously described snap action is obtained.
  • FIGS. 6 and 7 show a modification of the construction of FIGS. 2 through 4, and here the parts are correspondingly numeraled and separately identified by the use of the letter b."
  • the valves periphery rim 27b which extends above the upper level of the top of the valve, is made in tubular form by having the valves top formed with a downwardly extending groove 29.
  • This groove has an outer sidewall that extends angularly upwardly to form the rim 27b with a sharp edge, and its inner sidewall extends upwardly in a substantially cylindrical manner.
  • the thus-formed tubular portion of the valve may have substantially elastic deformability permitting it to seal very effectively against the inner surface 9b of the cup-shaped body without interfering excessively with the valves sliding motion.
  • valves body 13b is slightly tapered downwardly so that its upper portion fits the cylindrical wall 9b more firmly than its lower portion.
  • the inner surface of the closure 11b is shown as provided with a bead 29b so that in conjunction with the elastically outwardly springing rim 27b a double seal is pro vided.
  • sealing is also obtained where the sidewall of the valve, flexible or not, closes the ports 20 and 21 or 20b and 21b. Therefore, to this extent, a triple sealing is obtained.
  • the tubular stems hole 171) is shown by dotted lines being possibly positioned at a higher level than shown by solid lines.
  • this hole 17b is closed or seats on the sidewall of the hole 16b in the closure or gasket 11b and through which the stern 1512 projects.
  • the movable valve is made hollow and the metallic coil compression spring 31 biases the valve to its normally closed position.
  • the valve itself is made in the form of an inverted cup with its sidewall provided with longitudinally extending slots 32 which define depending cantilever springs for the valve itself.
  • the wall 9c of the cup-shaped body is provided with the bead 28c, the bottom edge of the movable valve resting on this bead when the valve is in its fully closed position. Adequate downward force on the valve stem c causes the spring portions of the movable valve to spring inwardly with the valve consequently moving downwardly with the desirable snap action.
  • valve has a substantially cylindrical exterior for its entire length which slidably fits the surface 9c.
  • the taper shown is exaggerated to show its presence.
  • the entire movable valve body forms a sliding fit with the cup-shaped part's inside, there being only a tighter or closer fit at the top portion of this body.
  • the bottom of the cup-shaped body may be made tapered as shown so that the springs defined by the slots 32, for the movable valve, spring inwardly with a wedging action when the valve is opened, providing valve closing bias similar to that previously described.
  • a metallic spring need not be used, although it can be as in the other examples, if desired.
  • tubular members 23 in FIGS. 2 and 3 and the corresponding members in the other figures are all shown as being longitudinally slotted. However, solid or unslotted tubular members might be used if made of material of adequate elastic properties and properly designed.
  • An aerosol valve assembly comprising a movable valve and a valve seat therefor, means for elastically biasing said valve to a normally closed position relative to said seat, an operator actuated by the application of manual force for moving said valve to an open position relative to said seat, and means for applying a resistance to movement of said valve when said operator receives an initial application of manual force and which suddenly releases said resistance with an increase in said force so that this increased force causes said valve to move to its said open position with a snap action; and further comprising a cup-shaped body, a closure for the top of said body and having an inner surface forming said valve seat, said valve being positioned inside of said body for movement axially with respect to the latter and having a top engagable with said valve seat, said operator being formed by a tubular stem extending upwardly from the top of said valve through a hole formed in said closure and said biasing means biasing said valve upwardly; and said body, said valve and said stem forming at least one fluid passage which is closed when the valves said top engages said
