Improved stopper, characterized in that it is constituted by a solid body obtained by molding plastic materials, whose body has an outer surface of curved-concave generatrix, also having an axial passage of reduced diameter that communicates both bases of the cap body, comprising the upper base a peripheral wing from which extends a radial strip topped by a vertical pivot acting as a stopper for the passage of the plug, said wing being combined with a lower rib that forms a socket receiving the edges of the hole provided in the container where the plug is attached.
