Aerosol packages usually comprise a valve unit situated in the neck of the container which is opened by finger pressure against an actuator dispcsed at one terminus of a valve stem. The valve unit has a movable valve body and associated hollow valve stem which unseats from a gasket, thereby permitting flow of product into a hollow valve stem (product conduit).
With certain products, e.g. paints, it is desirable that the valve stem be separable from the valve body in order to clean the product conduit should drying and resultant clogging occur. To provide the aforementioned valve stem removal capability, the valve stem, at one end, is molded integral to the valve actuator to thereby permit its separation from the valve body by pulling on the actuator. At the other end the valve stem mates with a movable valve body situated beneath a resilient gasket, the valve stem being passed through a central opening in the resilient gasket. The gasket seals the product discharge orifice in the valve stem when the valve is in a closed position. By depressing the SU2Scri' TU ''LIK c2T I WO 88/04266 PCT/US87/03182 -2valve stem, the product orifice in the stem is open to flow of product from the container.
More particularly, the aforedescribed aerosol valve comprises a container closure, commonly called a mounting cup, which is clinched to the container bead. Within and crimped to an upstanding central portion of the mounting cup, commonly called a pec-estal, is a valve housing having a resilient gasket disposed atop thereof, which gasket forms a seal between the valve housing and the mounting cup.
Disposed within the housing is reciprocable valve closing/opening member comprising a vaive body and valve stem, which body and stem have communicating for egress of the pressurized product to a discharge orifice situated in a finger depressible actuator.
The aerosol valve described above is commonly referred to in the aerosol industry as a "female" valve, in contrast to the so called "male" valve wherein the valve stem is molded integral to the valve body. United States Patent Nos. 3,033,473, 3,061,203, 3,074,601 and 3,209,960 describe aerosol valves of the "female" type and United States Patent 2,631,814 and aerosol valve of the "male" type.
Furthermore, in prior aerosol valves, the product orifice in the valve stem is formed by a radial pin extending laterally through the wall of the valve stem, a so-called "side action" molding operation.
'rhe presence of the "side action" pin necessitates the removal of the pin before ejection of the molded part, with a consequent time delay in the molding operation. Moreover, with orifice sizes commonly used in aerosol valves, the "side action" pin often breaks with consequent shutdown of the molding operation.
4~ 'I I-I 3a Broadly stated, the present invention is an improvement in an aerosol valve having a moveable, gasketed valve body-valve stem located within a valve housing, comprising a valve body having at least one upstanding wall defining a recess in the valve body and having a wall defining a recess in the valve body and having a slot extending from a top shoulder of the upstanding wall which slot communicates with the interior of the container when the valve is actuated; the valve t0 stem comprising a depending extension that frictionally and releasably engages within the valve body recess, said va)ve body and depending extension having a longitudinal opening therethrough and an orifice aligned with the longitudinal opening of the valve stem, said orifice communicating at one end with the slot in the recess of the valve body and at the other end with the longitudinal opening in the valve stem; and the central opening of the gasket sealing the slot in the upstanding wall of the valve body when the valve is in a closed position.

WO 88/04266 PCT/US87/03182 Additionally, in prior aerosol valves, the central opening of the gasket seals radially against the product orifice in the valve stem. This sealing of the valve stem orifice upon closure of the valve forecloses gravitational return of the product in the hollow valve stem from moving past the valve stem orifice with the often consequent result that residual product in the hollow valve stem drys and clogs the passage in the valve stem.
It is an objective of this invention to provide an aerosol valve that obviates the aforementioned disadvantages of prior art valves.

Figure 6 is a top plan view of Figure Figure 7 is an enlarged longitudinal partial section of the valve stem and valve body of Figure 1.
Figure 8 is a perspective view of the valve body of Figures 1, 2, 5-7.
Referring to the drawings, the mounting cup is generally designated as 10. Crimped to the mounting cup 10 is a valve housing 12 and a gasket 14.
Disposed within the housing 12 is the valve body 16 having a recess 22, which valve body is biased toward the gasket 14 by the spring 18. A conventional dip tube 46 is shown attached to the bottom of the housing 12. A valve stem, generally designated as 20, is disposed within the recess 22 (shown in greater detail in Fic:ure 5) in the top of the valve body 16 through the friction fitment of the depending extension 24 of the valve stem 20. Upstanding arcuate walls 26 (shown in detail in Figure 8) form the upper portion of the recess 22 and define a slot 21. Beneath the slot 21, defined by the upstanding arcuate walls 26, are grooves 32 in the side wall of the valve body recess 22, which grooves 32 communicate with the space or reservoir 34 situated in the valve body recess 22 beneath the valvb stem 20. An annular recess 50 is disposed in the top shoulder 40 of the valve body 16.
SU2,~Ti3T1TUT:. r2T VO 88/04266 PCT/US87/03 182 The valve stem 20 has an orifice 42 communicating with the space 34, which orifice in the preferred embodiment of the invention acts as a product flow control orifice. A recess 30 is formed in the base of the valve stem 20 having a shoulder 28 against which the arcuate walls 26 bottom when the valve body 16 and valve stem 20 are in assembled relation. The outer wall 48 of the recess 30 in the valve stem is tapered.
Actuator button 36 is mounted on the upper portion of the valve stem 20. An annular rib or barb 38 is formed on the Val ve stem 20, which rib 38 anchors the valve stem 20 to the actuator button 36 and facilitates removal of the Valve stem 20 from the valve body 16.
In the closed position of the aerosol valve, shown in Figure 1, the gasket 14 seals against the annular top shoulder 40 of the valve body 16 and the upstanding arcUate walls 26 of the valve body 16 to prevent passage of product through the slot 21.
In the open position of the valve, shown in Figure 2, pressure on the actuator button 36 depresses the valve stem 20 and the val.ve body 16 to expose the slot 21 to the pressurZized contents of. -the container, thereby permitting passage of the container contents through the slot 21, the grooves 32j the space 34, the OrIfice 42 to the discharge crifice 44.
The product passaqg formed in the valve stem and valve body of the subject invention require no "side actkcr' molding pins. Further disposing the orifice 42 on the discharge side of the space 34 serves the function of permitting product in the valve stem on the discharge side of orifice 42 to back flow into the space 34 and thus not dry and clog the product passage in the valve stem. Still further, disposing the~ orifice 42 on the discharge side of the space 34 SU ECI T UI ~i.Z WO 88/04266 PCT/US87/03182 -6creates a residue of propellant in space 34 upon closing of the aerosol valve, which residue will assist in purging the valve stem and actuator product passages of residual product to thereby avoid or reduce clogging.
In assembling the several valve components, a sub-assembly comprising the valve stem, valve body, spring and gasket is initially made. Such a subassembly properly orients and maintains the position of the gasket relative to the valve body, thereby enabling rapid assembly of the sub-assembly and other valve components without risk of dislodging the orientation of the gasket to the other components prior to permanent positioning of the gasket through crimping of the valve to the mounting cup.
The structure in the valve stem-valve body fitment portions that facilitates disposition and positional stabilization of the gasket onto the valve body is best shown in Figure 7. In assembling the valve unit the gasket 14 is passed over the outside surface of valve stem 20 and ultimately seated on the shoulder of the valve body 16. Movement of the gasket 14 to a seating atop shoulder 40 of arcuate walls 26 is facilitated by the sloped shoulder 48 the valve stem Moreover, the height of the upstanding arcuate walls 26 is preferably greater than the gasket chickness, so as to avoid the top shoulder of the arcuate walls 26 passing beneath the gasket 14 during pressure filling of the container with propellant body.
The structure designation numbers used herein in the description of Figures 1 and 2 likewise designate the same structural components in Figures 3-8.
