Abstract
An easy open pull-tab container and related method comprises a generally planar end having a line of weakness defining a tear line so that a portion of the end is partially removable, the tear line lying in the plane of the end. A pull-tab is provided for severing the portion along the tear line, with first and second portions of the end wall on opposite sides of, and spaced from the line of weakness, extending underneath the area adjacent the line of weakness and to form blunt, protective shoulders at the line of weakness. The protective shoulders are formed via first and second concentric grooves in the end, the grooves extending below the level of the end to form inner and outer beads, the inner bead extending substantially below the outer bead. A central bead is formed in the end between the first and second concentric grooves, the central head extending above the level of the end. The inner and outer beads are forced towards each other and toward the plane of the end until the inner and outer beads abut the center bead, but are spaced a distance apart approximately equal to the line of weakness.
