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 3):
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 having a housing hole diameter, and an elongate longitudinally oriented hollow two piece valve stem disposed within and longitudinally movable within said seal hole, said valve stem having an upper stem portion and a lower stem portion integral therewith with a longitudinal passage therethrough, said lower stem portion having a valve stem head designed to sealingly fit against said seal and having a stem head diameter greater than said seal hole diameter, said lower stem portion further having at least one radial port in fluid communication with said longitudinal passage, and a disc disposed above said seal and having a disc diameter, said disc diameter being greater than said seal hole diameter, said disc being fitted to said upper stem portion.
