Abstract:
A multi-piece valve stem. The multi-piece valve stem allows for interchangeability of component parts, without requiring several stems to fit related valves, as are commonly used for aerosol dispensers. The multi-piece valve stem also provides for assembly of valve stems having a larger head, and thus more seal area, than can occur with a single piece valve stem, as is conventionally used. Smaller stem bore diameters are also possible with a multi-piece valve stem.

Claim (Index 2):
A valve for selectively releasing a product from an aerosol dispenser, said valve having a longitudinal axis and comprising:\n a housing having a housing hole therethrough, a seal disposed within said housing and having a seal hole therethrough with a seal hole diameter, said seal hole being concentric with said housing hole, and an elongate longitudinally oriented hollow two piece valve stem longitudinally movable within said seal hole, said valve stem having an upper stem portion disposed above said seal and having a disc therearound and joined to said upper stem portion, said disc having a disc diameter greater than said hole diameter, said valve stem having a lower stem portion fitted to said upper portion, said lower stem portion having a valve stem head having a stem head diameter and being designed to sealingly fit against said seal.
