Abstract: An improved outlet valve assembly for fluid dispenser of a type having a pump which has a pump inlet coupled to a fluid reservoir and a pump outlet includes a pump tip having a first end adapted to be coupled to the pump outlet and a second end defining a conduit extending in a flow direction therebetween. A first annular protrusion extends radially inwardly within the conduit and a resiliently deformable valve member is received within the conduit. The valve member includes a valve head portion having one or more slits defining an orifice and a peripheral valve portion bounding the valve head portion, which is retained on the first annular protrusion. A vent-resisting member is received within the conduit and includes a perforated baffle adjacent to the upstream side of the valve head portion and an axially-extending sidewall which has a distal edge engaging the peripheral valve portion.

Abstract: An improved outlet valve assembly for a pump-type fluid dispenser includes a nozzle and a self-sealing slit valve having a valve head portion bounded by a peripheral sealing portion retained between the pump outlet and the nozzle. In further aspects, improved valve members, fluid dispensers, and a method for making a fluid dispenser are provided.
