Definitions
- This invention relates to a valve for a pressurized package commonly referred to as an aerosol package.
- Aerosol packages usually comprise a valve unit situated in the neck of the container which is opened by finger pressure against an actuator disposed 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) .
- valve stem 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.
- 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.
- 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.
- the product orifice in the stem is open to flow of product from the container.
- the aforedescribed aerosol valve comprises a container closure, commonly called a mounting cup, which is clinched to the container bead.
- a valve housing having a resilient gasket disposed atop thereof, which gasket forms a seal between the valve housing and the mounting cup.
- reciprocable valve closing/opening member comprising a valve body and valve stem, which body and stem have communicating passages 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 r 3,074,601 and 3,209,960 describe aerosol valves of the "female” type and United States Patent 2 r 631,814 and aerosol valve of the "male” type.
- 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.
- the 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.
- the "side action” pin often breaks with consequent shutdown of the molding operation.
- the 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 slot extending from the top shoulder of the upstanding wall which slot communicates with the interior of the container when the valve is actuated; a valve stem having a longitudinal opening therethrough and a member that frictionally and releasably engages within the valve body recess, said valve stem further having an orifice aligned with the longitudinal opening of the valve stem, which communicates at one end with the slot in the recess of the valve body and at the other end with the orifice in the valve stem; and the central opening of the gasket sealing the slot defined by the upstanding wall of the valve body when the valve is in a closed position.
- the aerosol valve of this invention includes a recess in the valve body beneath the valve stem orifice.
- Figure 1 is a longitudinal sectional view of the valve of this invention in closed position.
- Figure 2 is a longitudinal section of the valve of this invention in open position.
- Figure 3 is an enlarged longitudinal section of the valve stem of Figures 1 and 2.
- Figure 4 is a bottom plan view of Figure 3.
- Figure 5 is an enlarged, longitudinal partial section of the valve body of Figures 1 and 2.
- Figure 6 is a top plan view of Figure 5.
- 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.
- 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 Figure 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.
- 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 20 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 valve 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.
- 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.
- the product passages formed in the valve stem and valve body of the subject invention require no "side action" 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 creates 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.
- a sub-assembly comprising the valve stem, valve body, spring and gasket is initially made.
- Such a sub- assembly 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.
- 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.
- gasket 14 is passed over the outside surface of valve stem 20 and ultimately seated on the shoulder 40
- the height of the upstanding arcuate walls 26 is preferably greater than the gasket thickness, 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.
