<p>A tamper-evident closure comprises an envelope (10) having an opening (16) to its interior. A closure flap (20) is movable from an open condition in which access to the interior of the envelope can be reached through the opening (16) and a closed condition in which access to the interior of the envelope is substantially prevented. The closure includes a seal (90) applicable to the envelope (10) in the closed condition, the presence of the seal preventing opening of the envelope. Removal of the seal causes the seal to be visibly damaged or broken as evidence of tampering. In a preferred embodiment, the seal is a one-piece plastic moulding that it co-operates with a seal receiving assembly (40) on a panel of the envelope and a seal locating assembly (42) on the flap (20). <IMAGE></p> |
