  • Patent number: 4958755
    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. The valve stem base includes an inverted skirt peripherally mounted thereon that, with the lower end of the grommet define a circular path for dispensing the product.
