Abstract:
Apparatus for retarding oxidation of a liquid that only partly fills a container formed with an opening through which a liquid can be poured comprises a cap mountable adjacent to the opening, an inflation tube insertable through the cap, and an air bladder connected to the inflation tube and positionable within the container. A pump is connected to the inflation tube and positionable outside the container. A valve is connected to the pump and the inflation tube. An exhaust tube is insertable through the inflation tube and has an inlet portion positionable in the container and an outlet portion positionable outside the container. When the cap is mounted adjacent to the opening, the air bladder and the inlet portion of the exhaust tube are positioned within the container, the pump and the outlet portion of the exhaust tube are outside the container, and the pump is activated, the air bladder expands within the container and expels air therefrom through the exhaust tube, so that oxygen is substantially prevented from coming into contact with the liquid.
