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.
