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.
