Abstract: A pull tab for easy opening containers wherein the pull tab has an intermediate attaching portion in the form of a strap struck from the center of the tab body for securing the tab to the container wall by means of a conventional rivet. A first strap is defined by a cutout in the tab body. There is a second strap portion which is connected to the tab body but which has a longitudinal sliding connection with the rivet. This longitudinally elongated slot opening permits a force applying portion of the tab to shift longitudinally relative to the rivet with a resultant changing in the bending point or pivot point for the tab, thereby reducing prior experienced stresses and permitting the necessary opening force to be applied to the rivet through the pull tab without the customary tab failure problem.

Abstract: An end closure having a non-detachable flap partially severable from the end panel to provide an opening. The flap is recessed below the remainder of the panel and is broken away by a tab which fits into the recess. The tab is adapted to be pushed inwardly and, after rupturing the score between the end panel and the flap, functions to swing the flap inwardly about a hinge formed by an unscored area of the flap perimeter. The invention is primarily directed to a means of attaching the tab to the flap so as to provide a lost motion enabling the movement of the flap relative to the tab during the inward swing.
