Abstract: The disclosed invention is directed to a sealing and dispensing apparatus that is used to preserve the contents of a carbonated beverage container. It includes a novel double plug seal located in a plug fluid chamber having a wider portion and a narrow portion. The double seal plug engages at its forward end with the discharge port. The aft end of the double seal plug engages the narrow portion of the plug fluid chamber. Taken together, the double seals allow for reduced spraying and leakage of fluid from the apparatus, both during and after fluid is dispensed. The invention also relates to a novel method for attaching the plug to the actuator. It also relates to an improved design for attaching an apparatus to a beverage container, and a novel design for gradually reducing the pressure of the fluid to be dispensed, thus preserving the carbon dioxide or other gases within the fluid.
