Zusammenfassung:	A pump assembly which provides a frangible air vent mechanism for providing communication between the atmosphere and the interior of a bottle to which the pump assembly is to be coupled. A vent port is provided through a bottle cap member having an inner end open into the bottle and an outer end open to the atmosphere. A frangible plug member is received in the vent port with the frangible plug member when unbroken preventing flow through the vent port and the plug member when broken permitting flow through the vent port. A vent tab member is coupled to the frangible member with the vent tab member extending from the frangible member accessible on the exterior of the bottle cap member for engagement to apply forces to the vent tab that are translated to the frangible vent member to break the frangible member.
