Combination charging and dispensing valve for aerosol containers

摘要

An improved valve for pressurizing and sealing aerosoltype containers comprises a resilient valve member having longitudinally-shaped charging and sealing grooves adapted to engage the peripheral edge surface of an aperture in the container. When the valve's charging groove receives the aperture edge surface, the container is pressurized through longitudinally-extending, discontinuous recesses in the resilient valve member. When the resilient valve member is pushed inwardly, its sealing groove receives the aperture edge surface and the container is sealed. Especially configured recesses permit unrestricted movement of the resilient valve member as it travels from its charging groove to its sealing groove.
