Screw plug top with spring thread for container with lid (8) screwed onto container opening (1) has spring thread with several protuding pieces which are snapped into the threads of a multi-threaded screw thread (4). To release the plug, the protuding pieces are unscrewed from the thread. The protuding pieces are embodied as flexible flaps (9) and bend when sprung apart. The flaps have a constant cross-section over their length and can bend at their foot (f). They are placed at an oblique angle to the direction of release. |
