Abstract
An easy open container end closure utilizes a pair of angled force directing score lines to direct an upward closure opening force which is applied to a pull ring or pull tab to an initial break line of finite length. The force directing score lines allow the container lid to pucker and to direct the applied opening force to the initial break line. Once this line has severed, continued lid separation acts in shear at two points of separation. The result is a container end closure which requires substantially less opening force than do prior art devices.
