Abstract
1452422 Easy-opening containers E C FRAZE 21 Feb 1974 [28 Feb 1973] 7850/74 Addition to 1427024 Heading B8D [Also in Division B3] The easy-opening container wall of the parent Specification is modified in the region where tearing of the score line 23 commences by locally spacing the reverse bend 53, Fig. 12, from the wall 56. Thus the initial "pop" of the seam is facilitated and/or the subsequent initial pull-up of the panel. The score line 23 may extend beyond the bend 53 in a double bulge 23b, 23c, Fig. 6, but is radially inward of the bend 53 beneath the rupturing flange 39, Fig. 2.
