<p>Security seals (1) are used to indicate that a closed container has remained closed throughout a journey or during transport to show that its contents have not been tampered with. Once fixed such seals can only be removed by destroying them. A padlock-type security seal (1) includes a recess (10) in its body (2) accessible from the front face which houses a locking collet (11). The collet (11), in use, locks the leading end (4) of the hasp (3) of the seal (1) into the body (2). A cap (12) is welded onto the body (2) to close the recess (10) and seal the collet (11) into the body (2). Preferably, the body (2) of the padlock-type seal is chosen to be a colour which will give a good contrast with a barcode (14) applied to it. The colour of the cap (12) can vary from that of the body (2) to enable an audit trail of the seals (1). <IMAGE></p> |
