Abstract
An improved child-resistant self-opening end closure wherein the finger ring portion of the pull tab is nested between two concentric curved protrusions, formed in the end panel, which obstruct access to the ring and prevent grasping and lifting of the tab. To open the closure, an upwardly tilted nose portion of the tab is depressed, thereby causing the ring portion to tilt upwardly to a point whereat it may be grasped. The additional operation, which runs counter to a child's prior experience, renders removal of the closure beyond the capability of a young child.
