Abstract:

A liquid beverage dispenser includes a stabilizing base with a concave upwardly facing, internally threaded socket that can be screwed onto the externally threaded neck of a plastic beverage container to create a fluid tight coupling. The base supports the beverage container in an inverted orientation so that the mouth of the beverage container empties downwardly into the socket of the dispenser. The dispenser socket is provided with a vent tube that projects upwardly from an air relief port in the socket floor. A beverage drain port is also located in the floor of the socket, but is separated from the air relief port. A spigot is located at the outer periphery of the dispenser base so that liquid flows from the mouth of the bottle, through the drain port, and out of the spigot when the spigot is open. A rubber, one-way air relief check valve is mounted at the upper extremity of the vent tube and within the bottle. As the liquid beverage flows out of the bottle under the control of the spigot, the volume of the liquid beverage withdrawn is replaced by air that enters the bottle through the air relief port and the one-way valve. Air bubbles up from the one-way valve into the bottle replacing the liquid as it is withdrawn. Pressure is thereby equalized within the bottle.
