ABSTRACT:
A dispenser for a carbonated beverage bottle that uses the pressure from gases released by the beverage to eject the beverage. A plunger is depressed to unseat a check-ball floating in the beverage in a pick-up tube inside the bottle, the check-ball having been seated by gaseous and/or buoyant pressure in a seal to prevent escape of the gas or beverage. The neck and spout of the plunger are hollow, forming a passageway for the beverage to an opening in the spout. Beverage enters the neck of the plunger through opening in the circumferential wall of the neck when the plunger is depressed. Ribs on the interior wall of the seal are in frictional contact with the neck to prevent escape of the gas and the beverage. A tear-away collar permits stacking of the bottles and provides tamper resistance.
