Abstract

The valve is for use on a gas pressurized liquid food dispensing container or can, such as a whipped cream dispensing can. The valve includes a dish-shaped, preferably metal can top connector having a vertical opening up through which extends the vertical rod portion of a valve stem disposed within a passageway in a vertical tubular portion of a rubber grommet. The upper end of the grommet engages the lower end of an expanded head on the stem rod to hold the stem yieldingly in place in assembly. The horizontal lower end of the grommet abuts the lower end of the connector and the upper end of the horizontal base of the valve stem so as to releasably seal the connector opening therewith. An open-topped vertical cover is releasably secured by the grommet upper tubular portion, as by ribs or detents or threading and can be tilted sideways with the grommet upper tubular portion to tilt the stem base from its sealing position to release liquid from the can. The lower portion of the stem rod is generally conical and the grommet has an annular ring with pointed inner rim bearing thereagainst for improved sealing engagement, inadvertent 'blow-by' of liquid and solids and build-up of solids from the can. An annular ridge may be provided on the grommet inner passageway wall directly in the tilt path of the stem base to act as a fulcrum for earlier and easier dispensing from the can.
