  • Patent number: 5755352
    Abstract: A closure for a container is provided which includes a collar engaging the opening of the container, and a removable cap pivotally hinged to the collar by means of a double-fold hinge. When closed, the cap fits over the collar. The arc of travel of the cap as it pivots between its opened and closed position is such that the cap clears the cap engaging portion of the collar and the product in the container. The upper surface of the cap includes a chordal ridge which is adapted to be engaged by thumb pressure enabling easy grasping and opening of the container using one hand. The collar includes a cap engaging portion having at least one upstanding bead circumferentially disposed along an outside surface while the cap has at least one ridge circumferentially disposed along an inside surface configured to engage the upstanding bead when the cap is removably placed over the cap engaging portion such that the cap is retained on the collar.
