ABSTRACT:
A two component rotational safety cap for containers of harmful substances is disclosed. The cap is more positive and more reliable in its operation. It has several false depressed push button positions during unscrewing rotation to confuse children and a single unscrewing depressed location of the push button corresponding with alignment of two visual indicator elements on the cap components to facilitate cap unscrewing by adult users without difficulty or discomfort. The safety cap has only a single positive tightening element on each cap component, one of which elements is a spring ramp element on the inner cap component whose elevation relative to the outer cap component is controlled by fixed ramps on the outer cap component.
