ABSTRACT:
The present can lid has an upwardly-pojecting domed segment, a narrower marginal lip extending radially outward from the domed segment and terminating in intersecting arcuate score lines which are indented in the top of the lid, an upwardly-offset hollow rib extending across the domed segment and across the marginal lip at the ends of the score lines away from their intersection, and a short upwardly-offset hollow rib on the marginal lip at the intersection of the score lines. The short rib has a radially extending score line in the top which facilitates breaking the can lid first at the intersection of the arcuate score lines when the domed segment is pushed in, after which the can lid tears open progressively along these score lines out to the transverse rib.
