ABSTRACT:
A standard easy-open closure is converted to a child-resistant safety closure by the addition of an insert which is mounted on the rivet between the end panel and the tab. The insert extends beneath the piercing member and prevents cracking of the end panel score. The tab must be depressed, thereby allowing the insert to be rotated from beneath the piercing member, before the closure may be removed. These two additional operations, which must be performed in proper sequence, render removal of the closure beyond the capability of the young child.
