  • Retained ring tab
    Patent number: 4372462
    Abstract: A retained ring type lever tab for easy open containers. The tab is provided with two dog leg levers which join at the forward end to form a triangular nose. These levers which in cross section are made up of a pair of parallel flanges 0.050" in width connected by an outer curl of radius 0.030" are particularly effective in transferring the opening force to the displaceable panel in the end. The tab is characterized by a low weight and a high mechanical advantage.

  • Fracture resistant retained lever tab and method of manufacture
    Patent number: 4211335
    Abstract: A non-detachable fracture resistant lever tab for easy open containers. The tab is provided with a tongue with a high degree of bendability, the tip of which is staked to the central panel wall by means of a rivet. Bendability of the tongue is enhanced through the use of cooperative transitional planes of graduated coining which urge the bend line to form in an area of maximum coining. A method for manufacture of the tab is disclosed.
