摘要

The multi-section bellows seal (1) for containers (20) has an inner section (5) which has a pouring-out spout, a sealing edge (3) for sealing engagement with the edge of the container neck, and a slip-on/slip-off flexible bellows (4). A fixing ring (10) fits round container neck by a flange edge from the top, and retaining elements (16) which are brought into form-locking engagement are provided on the sealing edge on one side and on the fixing ring on the other side to prevent a radial inwards displacement of the sealing edge between the flange (11) of the fixing ring and edge of the container neck. An independent claim is included for a combination consisting of a multi-section bellows seal and container with a neck.
