The screw top of the hole of the container contains the sealing circular insert (2), fitting on the neck (14) of the bottle and having a bulge part in the central area (3) that together with the bottom (14) of the top (1) forms boundaries of the cavity (5) filled with air, functioning as an absorber of the impacts emerging during the liberation of CO¿2 from the beverage in the bottle. The sealing circular insert (2) is ensured against turning by means of the ratchet toothing (6). The tearable rataining ring (9) is perforated at an angle towards the vertical axis of the top (1). The method of making of the top (1) utilizes the thermal deformation to fix the sealing circular insert (2) made from thermally malleable plastic when pressing by means of the cylindrical thrust instrument (11). |
