Patent ID: 8087217

Claim:
A method of force expulsion of a cork closing a bottle, in particular a bottle of champagne or the like, by applying a sudden force to the cork, the method being characterized by the following successive steps: a) securing an impact part ( 16 ) to the body of the cork ( 40 ) so as to extend the cork axially from the bottle; b) orienting and holding the bottle ( 14 ) in a predetermined position so that the bottle extends essentially below a reference level ( 18 ), with the impact part emerging above said level, wherein the bottle is oriented in such a manner that the main axis of the bottle forms an angle lying in the range 90° to 45° relative to the strike direction of a striker surface against the impact part; and c) striking the impact part with the striker surface ( 22 ) in such a manner as to produce a force of sufficient amplitude to forcibly expel the cork solely by the fact of the striker surface striking against the impact part.
