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.

An easy open container end closure assembly comprising: means to attach said end closure assembly to a container; a container end lid portion of said end closure assembly, said end lid including a separable portion partially defined by an initial break line having a first thickness; force applying means carried by said separable portion of said lid generally adjacent said initial break line; and first and second spaced force directing score lines formed on said lid adjacent said force applying means and having converging first ends terminating at said initial break line whereby a container end opening force applied to said force applying means causes said lid to pucker intermediate said force directing score lines thereby directing the opening force to said initial break line.
