Document Type and Number:
Japanese Patent JP2003531076
Kind Code:
A
Abstract:
A dispensing system is provided for dispensing a product from a container having an opening. The dispensing system includes a spout for communicating with the container opening. The spout defines at least one discharge aperture, a distal seal surface located distally of the discharge aperture, and a proximal seal surface located on the exterior of the spout proximally of the discharge aperture. A nozzle assembly is mounted on the spout for movement between a retracted, closed position and an extended, open position. The nozzle assembly includes a nozzle having a dispensing passage around at least a portion of the spout, a proximal seal surface for sealingly engaging the spout proximal surface, and a distal seal surface located outwardly of the nozzle proximal seal surface for sealingly engaging the spout distal seal surface when the nozzle assembly is in the retracted, closed position. The nozzle assembly also includes a resiliently flexible valve that is sealingly disposed across the nozzle dispensing passage at a location distally of the spout distal seal surface and has an initially closed dispensing orifice which opens in response to a pressure differential acting across the valve.
