DUCKBILL VALVE ARRANGEMENT FOR A BEVERAGE DISPENSING CONTAINER

摘要

The present invention is directed to a duckbill valve arrangement (10) for a beverage dispensing container (70). The arrangement (10) comprises a tube (11) comprising a resilient tube wall (12) having an outer surface (15) and defining an internal passageway (13). The arrangement (10) further comprises a duckbill valve (30) mounted within the passageway (13). The duckbill valve (30) comprises a resiliently closable valve mouth (41) arranged to be opened upon compression of the tube (11). At least one groove (20, 21) extends along the outer surface (15) of the tube wall (12) for reducing the force required to compress the tube (11) and open the duckbill valve (30).
