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. The valve body includes a first valve body surface and a second valve body surface opposite the first valve body surface. A valve stem extends through the inner passageway and includes an outer stem surface, an inner stem surface opposite the outer stem surface, and a first orifice extending from the outer stem surface to the inner stem surface. A resilient member is disposed on at least a portion of the first valve body surface. The resilient member is made from a resilient polymeric material and has a non-linear compression profile.
