The present invention is an integrated hinged cover and locking snap to detect tampering of the bung plugs on plastic drums. The locking snaps will break upon an unauthorized attempt to remove the cap from the drum finish. The hinged cover also provides an annular locking ring on the inside surface for engaging an annular ring on the plastic drum finish. The living hinge allows the cap to fit over the annular ring on the drum finish. The living hinge also provides a tear tab member (pull-tab) to remove the cap from the annular locking ring. |
