Abstract

A pressurized canister with a reusable dispensing valve is provided. A metallic canister is provided with a threaded throat that is adapted to threadedly receive a valve assembly. An insert within the throat maintains a seal, for sealing the pressurized canister, and a membrane that is adapted to be pierced by a dispensing valve. This dispensing valve is spring biased and is movable within a pair of bores within the valve assembly. An outlet needle has an L-shaped passage that constitutes a portion of the valve such that movement of the valve inwardly not only pierces the membrane, but allows a radial leg of the L-shaped passage to communicate with the interior of the canister and dispense the pressurized gas therefrom. When the gas has all been dispensed, the valve assembly may be threadedly disengaged from the canister throat and reused upon threaded engagement with a new or refilled cansister.
