Abstract

See full text

An easy open can end having a retained tear strip extending diametrically part way across the can end defined by a score line of non-uniform depth, and a graspable pull tab, which may include fulcrum elements, one on either side of the center line of the pull tab, secured to the tear strip. Lifting of the pull tab initiates tearing of the score line which may be continued to form an opening in the can end. When the pull tab is pressed inwardly to a stored position against the can end, if desired, the tear strip doubles back upon itself to form an arcuate portion in the tear strip lying beneath the surface of the can end which operates to relieve stress and prevent metal fracture of the tear strip which could cause the strip to become separated from the can end.
