ABSTRACT:
A pressurized dispenser including a container, a mounting cup having a central opening therein, said mounting cup attached to said container, a dispensing means comprising a body member forming a tank and having an open top portion with a dispensing stem projecting therefrom through said central opening in said mounting cup, said body retained in said mounting cup, and a diaphragm interposed between said body and said mounting cup, sealing around said projecting stem at least when said stem is in an unoperated position, a passageway is formed in the body extending across the top of said body and through the body, the passage in communication with the tank in the area below the diaphragm, an annular gasket is interposed between the mounting cup and container, the gasket having an opening with the same profile as the outside of the body disposed so as to seal against the body to interrupt communication between the passageway and container, so that, during pressure filling, when pressure medium is supplied to the area of the tank below said diaphragm it flows across the top of the body and through the body to the gasket, deforms the gasket away from the side of said body permitting flow into said container at a fast rate.
