    摘要: 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.
