ABSTRACT:
A child-resistant container closure constructed according to the present invention comprises a disk shaped cover plate attached to body section formed as a substantially cylindrical wall. A movable handle or tab is attached to the cover plate to aid a user in pulling the closure from a container in which the closure is installed. A well or recess is provided in cover plate to house the handle in a closed position. A ridge on the end of the handle cooperates with a mating ridge in the wall of the recess to retain the handle in a closed position. A resilient spring is provided in the recess so that when the handle is released from the recess, it is urged into a position in which it may be conveniently gripped by a user. An undercut groove or notch is provided on the outside surface of the cylindrical wall adjacent the cover plate. The notch engages a mating lip or ridge extending inward from the inner surface of the mouth of the product container to secure the closure to the product container. The depth of the notch is gradually reduced along a predetermined angular portion thereof to reduce the amount of force required to remove the closure from the container.
