<p>The bottle top has its top (3) and its sealing face (6) manufactured in one piece. The neck of the top is manufactured with a clamping rim (9) which is contracted (7) and perforated (8). The bottle top is arranged with only one screw thread (4) to seal the bottle thread. The top can be fitted to a filled bottle, after preheating of the thermo-plastic bottle top, by pressing it vertically onto the bottle until the lower clamping rim engages the bottle neck and the sealing face seals the top surface of the bottle.</p> |
