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.
