ABSTRACT:
An end panel for an easy open end includes a pull tab fixed to the removable inside portion and a score line having two different defined depths, including a first severing depth passing under the nose of the pull tab and substantially all of the remaining areas except for an area rearward of the pull tab, where the score line extends to a second, shallower temporary retention depth in order to retain the rearward area with the outside portion as the inside portion moves outwardly away from the container during either inadvertent or intentional opening.
