Abstract: A valve assembly for a dispenser. The valve assembly includes a valve body that extends about a longitudinal axis and defines an outer surface and an inner passageway. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, a fin extending radially outward from the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. The fin operatively engages a portion of the inner passageway forming a seal therebetween and providing controlled dispensing through the orifice.

Abstract: A valve for an aerosol dispenser. The valve has a housing as a chassis for other components of the valve. The housing perimetrically joins the valve to an outer container for the aerosol dispenser. The housing has a hole with a moving valve stem to selectively dispense product, upon actuation. The housing, or portions thereof, may be crystallized, to provide strength and dimensional stability, to reduce leakage.
