ABSTRACT:
A dispenser for a liquid in a bottle has a housing adapted to screw onto a threaded neck of the bottle. A tubular valve plunger is located within an aperture in the housing to form a liquid passage between the housing and the valve plunger. The valve plunger includes a mechanism for releasably sealing the liquid passage. A vent plunger is within the tubular valve plunger forming a separate passage for air to enter the bottle as the liquid flows out. The vent plunger includes a mechanism for releasably sealing the air passage. When the dispenser is operated the air passage is opened first to release any gas pressure within the bottle, before the liquid passage is opened.
