Bottle stopper

Abstract

Summarizing, we may say that this invention involves a stopper for bottles of beverages in general, particularly for wine, champagne, cider, sodas, and the like, which comprises: a metallic cap with internal plastic plastering (liner) so as to attain airtight closure and a “twist-off” system or the like with screwed threads that enables a quick opening of the bottle; a plastic cube of adequate hardness, with negative impressions or locks that hold and coincide with the external locks in the metallic cap, and the external diameter of which has a number of vertical grooves that allow for an anti-turn locking mechanism when it is placed inside an external aluminum cover; an external aluminum cover, the internal diameter of which locks with the outside of the referred plastic cube, in a cylinder-like and closed manner on one end on which are set the two parts mentioned above. It may have different width and length according to the purpose it is intended to serve, and it has circular threads or frangible bridges in order to guarantee the security of the content.
