Tamper-proof and child-proof medicine bottle or the like

A tamper-proof and child-proof closure for a medicine bottle or the like. The closure consists of an inner cap having threads on its inner surface mating with threads on the bottle neck and an outer overcap enclosing the inner cap and normally rotatable relative thereto. Co-operating clutch means on adjacent surfaces of the inner and outer caps are engageable for unscrewing the inner cap by moving at least part of the overcap axially toward the bottle and then rotating the overcap. The overcap has a removable skirt on its lower edge which initially engages the bottle shoulder near the neck to prevent the overcap from being moved into clutch engaging position until after the skirt has been removed.
