A container for foodstuffs or other products has a tamper-evident locking means which comprises a post and a cooperating opening or recess. A fault zone is formed by a weakened area provided by, for example, a plurality of perforations formed in the post, or around the post, or around the opening or recess, and fault zone is thus which is weaker than the material of the container, and weaker than the locking means mechanism. As a result, the fault zone will fail upon exertion of a force which is less than the disengagement force otherwise required to unlock the locking means, thus providing physical evidence of tampering. |
