CLOSURE WITH INTERNAL FLOW CONTROL FOR A PRESSURE OPENABLE VALVE IN AN EXTENDABLE/RETRACTABLE NOZZLE

摘要

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 and a distal seal. 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. 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 and has an initially closed dispensing orifice which opens in response to a pressure differential acting across the valve. The nozzle assembly also includes a flow restrictor below the valve, and a distal seal for sealingly engaging the spout distal seal.
