A stay-on-tab container end having a panel wall with a tab attached by a rivet and having a tear panel. The tear panel being defined by a frangible score with a first end and a second end and a non-frangible hinge segment. A second groove is formed in the panel wall with a tail portion extending from the tear panel through the hinge segment. The second groove tail portion has a reduced residual differential compared to the frangible score residual. Also, the tail portion includes a curved terminal end that partially surrounds the second end of the score.

[ We claim:] [1.]1. An end member for a container having a circumferential sidewall, the end member having a peripheral seaming edge adapted to be integrally connected to the sidewall, and having a central panel wall with a vent region and a means for opening a frangible panel segment of the panel wall, the end member comprising;a primary score groove in the central panel wall defining an outer perimeter of the frangible panel segment, the score groove having a first end adjacent the vent region and a second end, the first end and the second end being separated by a generally linear hinge segment of the central panel wall, said hinge segment integrally connecting the frangible panel segment to an adjacent area of the panel; and,a second score groove adjacent the second end of said primary score and adjacent said hinge segment to direct fracture of metal of said hinge segment in a direction away from said second end of the score.
