Pressure cap for bottles, characterized by being constituted by a molded elastic capsule, with the lower edge of its walls externally provided with a reinforcing bead, and on the internal face of said walls of a circular rib with an edge, to exert pressure laterally from the outside inwards on the external surfaces of the neck of the bottle, also having a prolongation in tubular form that arises from the internal face of the horizontal upper partition, the outer diameter of said tubular body being equal to the internal diameter of the mouth of the a bottle, so that, when introduced into it and slightly compressed, said tubular body also exerts a certain radial pressure from the inside to the outside, on the internal surfaces of the neck, so that, combining said two pressures with that exerted by the face internal of the upper partition over the edge of the mouth, the total hermetic seal is produced.
