ABSTRACT:
A closure cap for containers of harmful products when rotationally tightened on the threaded container neck becomes freewheeling in the opposite direction of rotation and resistant to opening by a child. Indicator elements on the inner and outer cap components can be aligned to locate a push button of the outer cap component at a depressable position where a driving element thereof can engage an unscrewing abutment of the inner cap component. The two cap components have initial and final tightening abutments which are sequentially engaged during tightening rotation. The inner cap component has a ramp which coacts with the push button to elevate the push button above all abutment surfaces of the inner cap component during freewheeling of the outer cap component in the child-resistant mode.
