An improved pull tab for a child-resistant self-opening end closure of the type wherein the tab is nested between end panel protrusions which shield and obstruct access to the tab ring and prevent grasping and lifting of the tab and opening of the closure. The tab is formed with a short nose portion with a piercing member, and a bulged fulcrum which provide adequate clearance between the tab and the end panel to permit depressing the nose portion of the tab causing the ring portion to tilt upwardly to clear the shield and permit the ring to be grasped and pulled to open the container. |
