ABSTRACT:
A rectangular tape seal end closure for closing pour openings in a round end panel of a pressurized container wherein the tape extends to the circular peripheral seaming chuck guide groove. The tape has a pull ring pull folded over the body of the tape and normally would form corners therewith which would encroach upon the chuck guide groove. In this invention, these corners are cut off to clear the chuck groove and novel ribbing reinforcements are provided which reinforce the body of the tape to resist blow-out and which bridge the cut off areas and function to strengthen the tape to counter notch-effect stress concentrations because of cutting off of the corners.
