ABSTRACT:
An improved child resistant package comprising a container and closure and resilient means for normally urging the closure axially away from the container when the container is sealed by the closure. Cooperating sets of locking elements rim the container adjacent its mouth and are disposed about the inner surface of the depending skirt portion of the container for locking and maintaining the closure in a sealed position over the mouth of the container. One set of the locking elements comprise pairs of spaced apart projections which define a through-running channel therebetween. The other set of locking elements comprise corresponding latch members, each of which defines a stop element which is received in through-running channels and a retaining portion which acts against one of the paired projections to retain the closure from axial movement in opposition to the urging of the resilient member. In the event of the shearing of portions of the projections, the locking feature of the closure is retained by virtue of the through-running channel which permits the latch member to be positioned toward the container mouth with the surface of the stop element in contiguity with undamaged portions of the projections.
