Device for retarding oxidation of partly consumed bottle of wine

Apparatus for retarding oxidation of a wine or other liquid that only partly fills a container formed with an opening through which said liquid can be poured, said apparatus comprising:

• non-sealing cap means mountable adjacent to said opening;
• inflation tube mean insertable through said non-sealing cap means;
• air bladder means connected to said inflation tube means and postionable within said container;
• pump means connected to said inflation tube means and positionable outside said container;
• valve means connected to said pump means and said inflation tube means;
• and
• exhaust tube means insertable through said non-sealing cap means and having an inlet portion positionable within said container and an outlet portion positionable outside said container;
• whereby, when said non-sealing cap means is mounted adjacent to said opening, said bladder means and said inlet portion of said exhaust tube means are positioned within said container, said pump means and said outlet portion of said exhaust tube means are outside said container, and said pump means is activated, said bladder means expands within and forms a seal with said container and expels air from said container through said non-sealing cap means both through and exterior to said exhaust tube means, so that oxygen is substantially prevented from coming into contact with said liquid.
