An inflatable member fabricated of an elastomeric expandable material is provided. The inflatable member has a sack-like configuration and is provided with a substantially centrally disposed nipple. A plastic disc is secured to the upper portion of the inflatable member or formed integrally therewith and the nipple extends upwardly through a central aperture in the disc. The inflatable member is positioned within the neck of a bottle, especially a wine bottle, with the disc positioned atop the lip of the bottle. The inflatable member is then filled with a pressurized inert gas through the nipple causing the elastomeric material to expand and be forced into contiguous and coextensive relationship with an interior portion of the bottle neck, thereby hermetically sealing the bottle. The nipple is then heat fused to maintain the hermetic seal.

Apparatus for sealing the neck of a bottle, said neck being of a predetermined diameter, comprising a disc member, and an inflatable member, said inflatable member being made of a flexible but inelastic material and being sized so as to be of greater diameter than said predetermined diameter when fully inflated, means for securing said inflatable member with respect to the underside of said disc member, said disc member being adapted for placement upon the lip of said bottle neck, said inflatable member being adapted for insertion within the neck of said bottle, inflation means operatively associated with said inflatable member to permit the introduction of pressurized fluid into said inflatable member, whereby expansion of said inflatable member causes the same to conform to the configuration of the interior portion of said bottle neck and to form an hermetic seal therein, and means for sealing said inflation means after expansion of said inflatable member.
