(54) Cap of the tear-off type for bottles containing highly carbonated liquids


(57) The cap according to the present invention is characterized in that, at an intermediate working stage, on the top panel (10) thereof a hollow pin (24) is formed, said pin being riveted, at a subsequent working stage, after a bored gasket (18) has been put on it, so as to form a head (26) which fastens said gasket.
Therefore the certainty is achieved that the cap and gasket remain firmly bound to each other upon the opening of the bottle.
