Stopper for a bottle and sealing element for said stopper

Abstract

The present invention relates to a stopper for a bottle designed for commercial bottling of a beverage or liquid food, preferably a wine bottle, and a sealing element for sealing the stopper in the mouth of the bottle, which is separate from the bottle. The stopper comprises a stopper part for introduction into a mouth of the bottle, and a head part for remaining outside the mouth of the bottle, the head part having a diameter that is larger than that of the stopper part, wherein the stopper part comprises a an interlocking mechanism for engaging with a counterpart interlocking mechanism of the sealing element. The sealing element is configured to be forced against an inner wall of the mouth, thereby being brought into a sealed position, upon introducing the stopper part into the mouth, in which sealed position the stopper is held on the bottle. The interlocking mechanisms are configured to permit bringing the sealing element into an unsealed position by an unsealing action which comprises rotating the stopper with respect to the bottle.
