Abstract: A security seal is described which can be used to protect the closure device of a container so that a subsequent opening of the container will be evident. The seal comprises a strip of resilient plastic film with patches of a tamper-resistant adhesive at each end, leaving an adhesive-free gap in between. The seal is applied so that the adhesive patches adhere to the container to keep the adhesive-free section flexed closely over and spanning the closure device. Thus, when cut to release the closure part, the strip flexes outward to produce easily noticed loose ends.

Abstract: A closure for a container used in hospitals to store and transport items. The closure includes a cable tie with a locking eyelet at one end. The other end of the cable tie passes through an opening in the closure and then locks into the eyelet. The locking eyelet has a retaining element that prevents the removal of the cable end. The cable, when thus secured, prevents an unintentional opening of the closure and therefore an unintentional movement of a lid of the container to an open position. Preferably the closure is a falling latch and the cable passes through an opening in the falling latch. It is also secured around or to other elements to prevent the falling latch from moving to a position where the lid can open.
