ABSTRACT:
A bottle closure includes the unitarily-molded combination of: an internally-threaded sidewall; a tamper indicator ring; and a hinge connecting the ring to the sidewall. The hinge permits the ring to be shifted from an initial position to an installation position. The installation position is essentially coaxially aligned with the sidewall.
