Abstract: A safety closure and container combination is disclosed. The container and closure each have mating lugs which cooperate with each other to move the closure toward the container when rotated in a first direction and to move the closure away from the container when moved in a second direction. Cooperating stop surfaces are provided on the closure and container which engage when the closure is rotated in a direction to move it away from the container so that it is necessary to move the closure toward the container to allow the stop surfaces to move past each other thereby allowing the closure to be removed from the container.

Abstract: A child resistant closure or a container having a cap member and an outer ring. The cap has a lower internal threaded section and an outwardly directed flange with downwardly directed teeth at its top with a cylindrical part therebetween. The ring has internal threads and a flange with upwardly extending teeth. When the ring is rotated it first climbs up the threads on the cap and then can be lifted along the cylindrical part to bring the teeth on the ring into mesh with the teeth on a cap so that furthe rotation of the ring rotates the cap loosening it.
