摘要： Double-lever action, easy-open container structure with a unitary rivet securing the working end of a tab opener in aligned relationship with a starter section of an outer scoreline which defines a removable area. The direction of the outer scoreline from the narrow starter section through a wedge-shaped portion provides for a shearing action along the scoreline in place of the tensile stress breakage required by the prior art. Arcuate ribs assist in maintaining the shearing action by preventing bulging of the removable wall portion. A chisel pointed tab opener concentrates force to facilitate initial rupture.
