Abstract: The container (1) which can be sealed in a tamper-proof manner by a seal assurance means (5) has an outwardly projecting opening edge (2) and connected to the opening edge with sealing contact a cover (3) which is connected to the container (1) by the seal assurance means (5) in such a manner that non-destructive release is impossible. The seal assurance means (5) is formed on one side by a retaining ring (6) which encircles the container (1) below its opening edge (2) and on the other side by a cover part (7) which covers over the cover (3) of the container (1) at least partially. The retaining ring (6) is hingedly connected to the cover part (7) of the seal assurance means and at at least one area across the container and opposite the hinge connection (8, 9) there are, mutually engaging in such a manner that non-destructive release is impossible, locking means (10-13) which interlock the retaining ring (6) and the cover part (7) of the seal assurance means (5).
