A full aperture unseamed can end having a vent test rating of at least 620.5 kPa (90 psi) comprising: a peripheral curl capable of seaming together with a can body flange; a wall extending inwardly and downwardly from the peripheral curl; a center panel having an periphery and including a coined portion proximate a rivet; a first score disposed proximate the periphery of the center panel, the first score defining a removable panel; a tab, including a nose, mounted to the removable panel by the rivet such that the nose is disposed proximate the first score, the tab being elongate along a longitudinal axis (P L) that extends through a center of the rivet, the longitudinal axis being perpendicular to a lateral axis (T L) that also extends through the center of the rivet; and a second score disposed on the removable panel, the second score having (i) a central portion spaced apart from the coined portion, the central portion intersecting the longitudinal axis (P L); (ii) a pair of lateral portions (46a, 46b) each including a segment that is approximately parallel to the lateral axis (T L); and (iii) a pair of side portions (50a, 50b), wherein each of the side portions extend from a respective lateral portion, away from the lateral axis, characterized in that the second score further comprises a pair of check slots (45a, 45b) disposed on either side of the central portion, and each lateral portion (46a, 46b) extends from a respective check slot. a peripheral curl capable of seaming together with a can body flange; a wall extending inwardly and downwardly from the peripheral curl; a center panel having an periphery and including a coined portion proximate a rivet; a first score disposed proximate the periphery of the center panel, the first score defining a removable panel; a tab, including a nose, mounted to the removable panel by the rivet such that the nose is disposed proximate the first score, the tab being elongate along a longitudinal axis (P L) that extends through a center of the rivet, the longitudinal axis being perpendicular to a lateral axis (T L) that also extends through the center of the rivet; and a second score disposed on the removable panel, the second score having (i) a central portion spaced apart from the coined portion, the central portion intersecting the longitudinal axis (P L); (ii) a pair of lateral portions (46a, 46b) each including a segment that is approximately parallel to the lateral axis (T L); and (iii) a pair of side portions (50a, 50b), wherein each of the side portions extend from a respective lateral portion, away from the lateral axis, (i) a central portion spaced apart from the coined portion, the central portion intersecting the longitudinal axis (P L); (ii) a pair of lateral portions (46a, 46b) each including a segment that is approximately parallel to the lateral axis (T L); and (iii) a pair of side portions (50a, 50b), wherein each of the side portions extend from a respective lateral portion, away from the lateral axis, characterized in that the second score further comprises a pair of check slots (45a, 45b) disposed on either side of the central portion, and each lateral portion (46a, 46b) extends from a respective check slot.
