A-412 SUNBEAM ABSTRACT OF THE DISCLOSURE: A threaded closure having both a tamper indicating and a non-backoff feature which locks the closure to a con- tainer to avoid unwanted loosening. The closure takes the form of a one piece cylindrical cap with an inwardly directed bead at its open end. The cap bead engages a complimentary bead on the neck of the container as the cap is screwed onto the container, and the cap bead snaps over the container bead to form a non-backoff seal. The cap has a tamper indicating band attached to its lower end by frangible webs. The band and container have complimentary stop means which coact to restrain movement of the band when the cap is unthreaded, fracturing the frangible webs giving an indication of tampering or initial opening.
