Safety closure for containers

In a child-resistant closure for a product container having:

• a body wall, the body wall having an exterior surface, a cover plate attached to the body wall, and first retaining means extending along the exterior surface of the body wall near the cover plate for engagement with a second means extending circumferentially on said product container, said first and second retaining means cooperating to retain the closure in a predetermined position in the container but to release the closure when a sufficient force is applied thereto;
• the improvement wherein:
• a portion of one of said retaining means has a reduced size whereby the force required to release said closure from the container is reduced;
• said closure comprises a handle, a recess in the cover plate for receiving the handle, the handle being releasably retained by the cover plate in a closed position in the recess, and resilient means disposed in the recess for urging the handle into a position angularly displaced from the cover plate whenever the handle is released from its closed position;
• and said handle has one end thereof hinged to said cover plate and said resilient means contacts said handle adjacent said one end;
• and
• said resilient means is a leaf member extending from a bottom wall surface of the recess.
