Abstract
A child-proof closure device for containers has an inner cap for securement on the container neck, and an outer cap rotatable on the inner cap between positions in which dispensing apertures in the caps are respectively aligned, to permit dispensing of the container contents, and covered, to prevent such dispensing. A square control projection on the inner cap is normally engaged with a star-shaped opening in the outer cap in one of positions angularly spaced by 45.degree. to prevent rotation of the outer cap, and can be disengaged for rotation by axial inward pressure to resiliently deform the inner cap. A ring of projections on the outer cap can engage in corresponding depressions or in the dispensing apertures of the inner cap.
