Abstract
A method and apparatus for venting a filled bottle closed by a stopper is disclosed. The venting is designed to equalize the pressure between the interior of the bottle and the atmosphere such that the stopper inserted into the filled bottle is not forced out of the bottle by excess pressure in the bottle. The venting may be accomplished by deforming the stopper in the bottle opening to form an air-outlet opening in the region sealed by the stopper and the bottle. The venting may be implemented by a squeezing device arranged on at least one side of the stopper, the squeezing device being active in a direction perpendicular to the central axis of the bottle opening.
