ABSTRACT:
A two-piece child-resistant closure comprises nested inner and outer closure members. Sets of lugs on the inner surface of the outer member panel and the outer surface of the inner member panel engage each other when the outer members rotated for application of the closure to a container, but cam past each other on inclined surfaces when the outer closure is rotated in the removal direction. The panel of the outer closure member is resiliently deformable to bring the noncamming surfaces of the lugs into engagement for removal of the closure.
