AEROSOL VALVE ~lOUN~ING CUP
BACKGROUND
Aerosol dispensing containers have found widespread use in the packaging of fluid materials including a variety of both liquid and powdered particulate products. Such containers are provided with a valve-controlled discharge orifice and operate by the action of a volatile propellant which is confined within the container together with the product to be dispensed. Because the propellant has an appreciable vapor pressure at room temperature, the product in the closed container is maintained under superatmospheric pressureO
A typical aerosol unit comprises a hollow cylindrical containQr which is tightly closed at one end and is provided with an opening at its opposite end for receiving a dispensing valve assembly. A closure, commonly referred to as a mounting cup, serves as the closure for the container and as a support for the valve assembly.
~:2~
Typically, the mountlng cup comprises an annular panel surrounding an upstanding cylindrical apertured pedestal for retaining the valve assembly, a cylindrical skirt extending from the periphery of the panel, and an annular channel extending outwardly from the edge of the skirt.
When the mounting cup is placed in sealing position on the filled container, the channel is positioned over the bead surrounding the container opening and the lower ~ortion of the skirt adjacent the channel is flared outwardly toward the container wall adjacent the bead. To ensure adequate sealing between the closure and the container, the cup is provided with a gasket in the annular channel of the cup.
The gasket may be a flat annulus cut from suitable resilient material, may be formed by flowing in and drying a liquid gasket-forming material, or preferably, may be formed by advancing a tubular sleeve over the skirt and into the annular channel as is described in Canadian Patent No. 1,188,659 issued June 11, 1~85 and Canadian patent application Serial No. 411,683 filed September 17, 1982.
Valve mounting cups normally are sold as complete assemblies with the valve secured in the pedestal portion and often with a product eduction or dip tube affi~ed to the valve. The assembly also may include a valve actuator or button having a discharge orifice and associated structure appropriate for dispensing the particular product. The empty containers are obtained from sources separate from the sources of the valve assemblies.
Standards of sizing tolerances have been established to assure that the bead or curl of the container opening and the annular channel of the mounting cup properly mate.
~.
~3 ~ 6 The product to be dispensed, the propellant by which it is to be dispensed, the container, the mounting cup and valve assembly-, and the valve a~tuator are brought together to provide the completed aerosol dispenser. A popular technique for rapidly charging the dispenser with propellant is to associate loosely the mounting cup assembly with the product-filled container, to force a predetermined quantity of propellant between the mounting cup and the container bead, and then to secure the mounting cup to the container by appropriate deformation of the mounting cup skirt below the container bead.
Propellant charging by this technique can be accomplished rapidly because the area available between the mounting cup and the container bead is large. This technique is referred to in the industry as "under-the-cup" filling.
A further technique for rapidly charging the dispenser with propellant is through a system referred to as "pressure filling~. In such a system, the mounting cup, with a crimped-in valve, is clinched onto the bead of the container prior to filling the container with propellant, the propellant being passed through or around the valve, or a combination of both. However, prior to passing the container to the propellant filling station, the mounting cup, with associated valve, is loosely associated with the container, as in ~under-the-cup~ filling.
In both "under-the-cup" and "pressure ~illing", the eduction or dip tube of the mounting cup assembly acts as a spring and tends to lift the mounting cup off the container with which the assembly is loosely associated. Further, the ~4--mounting cup assembly may be dislodged from the container by jarring as the container and mounting cup assembly are advanced to the propellant charging head or station. In order better to retain the cup on the container, small depressions have been provided in the inward facing surface of the mounting cup skirt to form minor protrusions on the outward facing surface of the skirt. These minor protrusions define a diameter slightly larger than the interior diameter of the container opening at the bead whereby the mounting cup can be snapped onto and frictionally be retained in place on the container bead. The interference or overlap of these different diameters must be sufficien~ to resist lifting by the dip tube, yet allow lifting of the cup in the propellant charging head, or other station where it is useful to remove the ; mounting cup. Consequently, small variations in the diameters of the mounting cup skirts and the interior diameters of the container beads, all within the tolerances allowed by the adopted standards for these dimensions, lead to a variation in the amount of interference. Some mounting cups will fit too loosely and some so tightly as to cause scratching of the protective coatings often applied to the interiors of the containers, or scarring of the container bead itself, particularly if the container is aluminum. Where the gasket is of the desirable tubular sleeve variety described in the patent applications cited above, the rush of ; the propellant past the gasket sleeve occasionally drives the gasket from the mounting cup channel onto the container bead. When the cup is brought down and affixed to the container, indentation of ~ rp~ ~
~6 - the gasket caused by passing the prior known protrusions may result in leakage paths or cracks in the gasketO
In the case of "cut~ gaskets, a term familiar to those skilled in the art, the location of the protrusions at the outer margin of the annular channel 1~ serves to confine the cut gasket in its proper position in the channel 18 during the transportation of the aerosol valve apart from the container.
~RIEF SUMMA~Y OF THE INVENTION
In accordance with the present invention, the outer peripheral margin of the annular channel of the mounting cup is provided with at least one inwardly extending depression which forms a shallow protrusion which frictionally engages the outermost extent of the bead surrounding the container opening. Preferably, a plurality of protrusions are formed. These protrusions serve to retain the mounting cup and valve assembly in place on the container as it is advanced to the propellant charging or other station. Location of shallow protrusions on the outer margin of the annular channel of the mounting cup provides a number of advantageous results. The protrusions enyage the outer surface of the bead surrounding the container opening where any scratching of the bead or of a protective coating is unimportant because that surface is not in potential contact with the product. The outer margin of the annular channel of the mounting cup is relatively resilient when compared with the relatively rigid skirt wall where -6~ 6 protrusions previously were locatedO This resilience permits springlike gripping of the container bead by the protrusions to thereby better accommodate tolerated variations in dimensions of the bead and cup.
The manufacturing technique required to make the protrusions in accordance with the present invention can be a simple linear reciprocation of a tool past the outer margin of the mounting cup, whereas the tooling required for forming the previously known protrusions in the skirt wall requires more mechanically complex radial advancement and retreat of a plurality of tools which must be halted with precision to form depressions of precise depth. Not only iæ the tooling required for the present invention simpler, it inherently produces precise depression depth. A
still further advantage is that the simplicity of tooling required allows the marginal depressions to be formed long after the mounting cup has been made, thereby obviating the need of the user to inventory separately mounting cups with and without protrusions.

DETAILED DESCRIPTION OF INVEN~ION
The drawings illustrate an aerosol valve mounting cup in accordance with the presen~
invention. The mounting cup comprises an annular panel 10 which surrounds an upstanding cylindrical pedestal 12 for retaining a dispensing valve (not shown)O An aper~ure 14 in the top end of the pedestal 12 accommodates the hollow stem of the valve upon which an actuator or button is placed.
~he annular panel 10 is bordered by a cylindrical skirt portion 16 which terminates at its upper end in an annular channel 18. As is shown in Figure
2(a~, the annular channel 18 engages a toroidal bead 22 which surrounds the opening of the aerosol container 20. The mounting cup is retained as a permanent closure of the container by a radially ; outward deformation ~not shown) worked into the mounting cup skirt 16 after the container has been filled and the cup has been positioned.
Frequently, the outward deformation is an outwardly extending bulge formed by a segmented spreading tool associated with the propellant charging station. A gasket 30 of resilient material ensures a pressure-tight seal between the annular channel 18 of the mounting cup and the bead 22 of the container 20~ The gasket 30 here illustrated is of the tubular sleeve variety described in United States Patent Applications 112,791 and 302,442. In Figures 2(b) and 2(c), parts corresponding to that shown in Figure 2(a) are similarly designated.
In accordance with the present invention, the peripheral margin of the annular channel of the mounting cup is provided with at least one protrusion sufficient to effect an interference fit wi~h the bead of the container such that the mounting cup is prevented from being dislodged from the container during travel to the propellant filling and clinching stations, the former in the case of "under-the-cup" filling and the latter in "pressure fillingn; said interference fit being limited in magnitude in the case of "under-the-cup"
filling so as to permit removal of the mounting cup during propellant filling. The magnitude of the interference fit is also limited where any processing requires removal of the mounting cup.
In a preferred form of the present invention, the peripheral margin of the annular channel 18 of the mounting cup is provided with a plurality of circumferentially spaced indentations 40 which form inwardly extending protrusions. A
circle defined by the inward extent of the protrusions has a radius R (shown in Figure 3) slightly smaller than the radius of the exterior extent of the container bead 22. The difference in dimensions provides an interference fit when the : cup is placed upon the container to cause a frictional retention of the cup on the bead. Since the protrusions 40 are on the peripheral margin or free edge of the cup, the cup margin radially can expand resiliently to provide a spring bias to : promote the grip exerted by the protrusions 40 upon the bead 22. The prior known location of protrusions on the relatively rigid cylindrical wall of the skirt 16 of the cup lacks much of the spring bias of the instant location. Because of ~ ~2~
the resiliant spring bias afforded by the location of the protrusions 40 at the outer margin of the annular channel 18, the frictional grip with which the mounting cup temporarily is retained on the container virtually is independent of, and easily accommodates, variations in the dimensions of the mounting cup and container bead. The grip is reliable. Elimination of protrusions from the skirt portion 16 eliminates any tendency to scratch or scar the container bead, or protective coatinys, or the gasket itself.
While the protrusions 40 can be formed in many ways, the simplest and most reliable way is to axially advance a forming tool past the outer margin of the annular channel 18 of the cup to thereby form depressions in the perimeter of the cup. Axial advance of the tool obviates the need to regulate precisely the stopping motion of the tool as is required to form radially the prior known depressions in the skirt 16. The tool here simply reciprocates past the edge of the cup to form depressions of the identical depth with great accuracy and reproducibility.
Frequently, the outward deformation is an outwardly extending bulge formed by a segmented spreading tool associated with the propellant charging station. A gasket 30 of resilient material ensures a pressure-tight seal between the annular channel 18 of the mounting cup and the bead 22 of the container 20~ The gasket 30 here illustrated is of the tubular sleeve variety described in United States Patent Applications 112,791 and 302,442. In Figures 2(b) and 2(c), parts corresponding to that shown in Figure 2(a) are similarly designated.
In accordance with the present invention, the peripheral margin of the annular channel of the mounting cup is provided with at least one protrusion sufficient to effect an interference fit wi~h the bead of the container such that the mounting cup is prevented from being dislodged from the container during travel to the propellant filling and clinching stations, the former in the case of "under-the-cup" filling and the latter in "pressure fillingn; said interference fit being limited in magnitude in the case of "under-the-cup"
filling so as to permit removal of the mounting cup during propellant filling. The magnitude of the interference fit is also limited where any processing requires removal of the mounting cup.

Since the protrusions 40 are on the peripheral margin or free edge of the cup, the cup margin radially can expand resiliently to provide a spring bias to : promote the grip exerted by the protrusions 40 upon the bead 22. The prior known location of protrusions on the relatively rigid cylindrical wall of the skirt 16 of the cup lacks much of the spring bias of the instant location. Because of ~ ~2~
