发明名称 FLUID DISPENSER POUCH WITH VENTURI SHAPED OUTLET
摘要 A pliable, fluid dispensing pouch is provided which includes a flexible shot-chamber having a venturi shaped outlet passageway leading to a discharge opening at one end of the pouch. The discharge opening is initially sealed closed by the presence of a sealing tab. The discharge opening is unsealed by tearing off the tab. The venturi shaped outlet passageway has a throat section in which a liquid meniscus forms during use which acts to prevent leakage from the pouch when not in use.
