ABSTRACT An integrally molded, unitary, plastic dispensing closure comprising a body, a lid, and a "living" hinge that joins the lid to the body. Cams and cooperating wall surfaces in the vicinity of the hinge provide forces that temporarily deform the hinge, within its plastic limits, and facilitate the movement of the lid to either an opened, or a closed, position. In one embodiment, recesses are formed at the rear of the closure body to accommodate the cams when the closure is in its closed position. In another embodiment, recesses are formed in the skirt of the lid to accept upwardly extending posts, and a cavity is defined in the upper surface of the closure body to accept cams, or lugs, depending below the lid. An efficient, anesthetically pleasing, low profile dispensing closure is achieved in each instance.
