Stopper, of the type consisting of a cylindrical body with a closed base, provided with a thread and a gasket fitted in its bottom and applicable against the mouth of the container, essentially characterized by the fact that in its bottom it has an annular rib of circular outline whose presence defines in the alluded bottom a similar annular housing in which the gasket immovably fits, which on its face adjacent to the mouth of the container presents a plane not parallel to the edge of the neck on which it must be applied in such a way as to establish a contact as a ring-shaped crown of small width capable of small displacements when receiving the pressure that ensures an effective closure.
