1. A container comprising:
an end wall having a rivet and a frangible score line that defines a curved tongue shaped panel having a semicircular arcing portion from a first lateral side to a proximal side and to a second lateral side, continuing to a distal looping portion that encompasses the rivet on a distal side and the first lateral side, the frangible score line terminating at each end substantially on a radial line extending from a lever mounting hole; and
a tab that is riveted to the end wall to act as second-degree lever and comprising:
a first actuating point extending toward the distal looping portion of the frangible score line;
a second actuating point extending across a second lateral side portion of the frangible scored line; and
a fulcrum portion extending opposite to the first actuating point and terminating within the curved tongue shape,
wherein lifting of the first actuating point pulls upward on the curved tongue shaped panel at the distal looping portion imparting a shear force of the frangible score line to initiate upward rolling of an extended portion of the curved tongue shaped panel; and
wherein:
actuation of the first actuating point folds an extending portion of the curved tongue shaped panel proximally onto the curved tongue shaped panel;
the frangible score line terminates at each end substantially on the radial line extending from the rivet toward the first lateral side; and
actuation of the second actuating point upwardly rolls the folded extending portion of the curved tongue shaped panel toward the first lateral side; and
continued actuation of the second actuating point folds back distally the rolled curved tongue shaped panel onto the end wall.
