Abstract: A safety cap, having an inner cap for covering a container and an outer cap covering the inner cap for selectively rendering the inner cap child resistant, is provided. The inventive safety cap includes a fixing mechanism for selectively fixing the inner and outer caps together, the fixing mechanism being preferably movable from a first position to a second position. When the fixing mechanism is in the first position, the outer cap is rotationally fixed with respect to the inner cap, and when the fixing mechanism is in the second position, the outer cap is rotationally independent of the inner cap. Thus, when the fixing mechanism is in the first position, the inventive cap functions like a conventional non-safety cap. When the fixing mechanism is moved into its second position, the outer and inner caps are made rotationally independent, and thus the cap of the invention functions like a safety cap requiring simultaneous downward force and twisting to remove.
