Abstract:
A dispensing system for dispensing a product from a container having an opening, said system comprising:a spout for communicating with said container opening and defining (1) at least one discharge aperture having a fixed geometry at a stationary location relative to said container, and (2) a distal seal surface located distally of said discharge aperture relative to said container; a nozzle assembly which is mounted on said spout for movement between a retracted, closed position and an extended, open position, and which includes (A) a nozzle having (1) a dispensing passage around at least a portion of said spout, (2) a distal seal surface for sealingly engaging said spout distal seal surface when said nozzle assembly is in said retracted, closed position; (B) a resiliently flexible valve that (1) is sealingly disposed across said nozzle dispensing passage at a location distally of said spout distal seal surface, and (2) has an initially closed dispensing orifice which opens in response to a pressure differential acting across said valve; and (C) a flow restrictor that is disposed across said nozzle dispensing passage at a location between said valve and said nozzle distal seal surface to restrict flow toward said valve as said nozzle assembly is moved to said retracted, closed position.
