ABSTRACT:
An easy open can end is disclosed having an attached tear strip across a portion of the can end outlined by a score line, and a round-shaped pull tab secured to the can end adjacent the attached tear strip, the pull tab including a nose portion having a clevis formed in an offset location relative to the pull tab's longitudinal centerline, the can end including a pivot ridge member formed in a centered position relative to the logitudinal centerline of the attached pull tab for assisting in maximizing the offset forces applied by the pull tab's nose portion. The offset clevis operates to create reduced opening forces when opening the can end, including a reduced initial "pop" pressure and a reduced "tear" pressure. These reduced forces result by having the offset clevis cause the initial "pop" opening to occur along only one side of the tear strip's score line and then the opening tear occurs sequentially along the remainder of the score line. This permits use of a score line of reduced depth, thereby leaving additional residual metal at the score line area, which increased residual metal results in less can leakage due to less incidents of unwanted score line fracture. The present invention's offset clevis tab pull is usable with can ends formed of steel and aluminum.
