ABSTRACT:
A tamper indicating, child resistant closure is provided by a one piece threaded cap having a non-backoff feature. The child resistant component is provided by a squeeze and twist lock having a deflectable tab which cooperates with a radially extending container abutment spaced from the container neck. A radially extending tamper indicating block attached to the cap skirt by a frangible web also aligns with the container abutment and prevents opening unthreading until the block is removed. The non-backoff feature is provided by an inwardly directed flange at the bottom of the cap skirt cooperating with a container bead.
