Abstract
The invention concerns a device for sealing a bottle containing a sparkling wine and includes a stopper, particularly made of cork or a synthetic material, capable of being inserted in the neck of the bottle, maintained thereon by a wire cap, and run through in the axial direction, by a conduit having first and second ends capable of communicating respectively with the bottle's internal volume and external volume. The second end is closed by a retractable closer. The device is characterized in that the stopper is axially run through by an orifice designed to receive the conduit and having an adjusted and tight cross-section relative to the conduit external section, the latter being provided at its second end, with a support flange capable of resting against the stopper upper surface.
