ABSTRACT:
A valve in which standardized, interchangeable components are used for converting the valve to use either in a manually operated pump or an aerosol valve. A poppet member is reciprocable in a valve chamber between a flexible valve housing and a main cylinder housing. By making minor modifications to the poppet member and cylinder housing the valve can be adapted or converted to use either in a manually operated pump dispenser or an aerosol dispenser. Unique valve retaining means for attaching a valve to a container is also disclosed. In one form, snap detents secure together peripheral flanges of the valve housing and cylinder housing and also secure the housings to the container neck. In another form, interfitting structure on the flanges align the housings relative to one another, and a gasket is interposed between the flanges so as to seal the flanges relative to one another and relative to the container neck, with a retaining ferrule engaging and securing the flanges to the container neck.
