发明名称 Delivery valve and nozzle unit
摘要 A removeable and replaceable self-sealing valve formed of resiliently flexible plastic which has inner and outer concentric walls spaced to provide an axially inwardly-opening socket for receiving the outer end of a semi-rigid plastic spout carried by a flexible plastic bag. The spout has one or more inner anular sealing ribs formed therein at a location spaced axially-inwardly from its lip and the inner wall normally resiliently engages this seal. A toggle lever is connected to the inner wall to flex it so that a portion thereof is flexed away from the sealing rib to open a dispensing passage to an outlet in the outer wall beyond the spout lip. A removable seal retainer insert holds the inner wall in sealed position until the valve is to be used.
