Abstract
Abstract A safety cap for use on bottles, consisting of a cap within a cap arrangement, is provided. The inner cap is designed for being threaded onto the neck of a bottle for closing the opening. Over this inner cap, there is mounted an outer cap which, by means of a ratchet arrangement, interlocks with the inner cap when it is turned in a clockwise direction to apply the inner cap to the bottle. When the outer cap is turned in a counter-clockwise direction in an attempt to remove the inner cap from the bottle, the ratchet arrangement does not interlock, but turns freely about the inner cap without turning the same. However, it may be made to interlock with the inner cap when it is desired to remove the same from the bottle, by pressing down on the concave top of the outer cap thereby engaging certain stops.
