Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A closure for a container end member having a center panel portion and a peripheral chuck wall and a chuck-receiving annular groove in the panel adjacent the chuck wall and having pour opening means disposed in close proximity to said groove; a tape of rectangular shape having a body portion and a finger-grip lift portion folded over the body portion and forming therewith a fold juncture at one end of the body portion; means for removably connecting said body portion to said center panel portion in a position disposing said folded edge proximate to said chuck wall chordally with respect to said groove, said tape in the region of said fold juncture being narrower than said body portion and thereat defining stress-concentrating notches in opposite edges of said tape, and means on said body portion and said lift portion reinforcing said tape in said region.
Claim 2
Dependent Claim
145 words
