Abstract

A child-resistant screw-on closure is provided with the closure having an audible close indicator signal and formed as a three-element closure. The outer cap is arranged for rotation relative to the centrally located middle cap and cooperates in a torquing manner with the middle cap so that, as the closure is rotated to close the container, the frictional engagement means engages the camming surface of the middle cap and until the frictional engagement means is rotated past the front end of the cam surface over the abutment point and onto the trailing end to produce the audible closure-state indicating 'click' signal. Thus, the closure provides the user with a readily apparent audible indication as to whether the container closure is in its fully closed or container-sealing condition.
