    摘要： 1,219,061. Easy opening cover for a container. CONTINENTAL CAN CO. Inc. 16 Jan., 1969 [11 March, 1968], No. 2681/69. Heading B8D. A rectangular easy opening panel 17 for a container has indentations 33 and a central depression 23 which receives the ring of a pull tab. Weakening line 21 defines the tear off panel and is spaced from a shallower line 22. A nose on the pull tab breaks the weakening line in the usual way and the tab body is secured to the panel between the depression 23 and the score line by an integral rivet 18.

    摘要： 1,045,670. Stamping. CONTINENTAL CAN CO. Inc. Aug. 2, 1965 [Nov. 25, 1964], No. 32979/65. Heading B3Q. [Also in Division B8] Score lines 15, 16, Fig. 4 (not shown), which may be continuous to form a removable portion in a can end, are reduced in cross-sectional area over a limited part by punching-out a recess 24 between the score lines, thereby causing the metal of the can end to flow outwards from the recess 24 and into the space at 25 resulting from the formation of the score lines. Ribs 27, 28 are formed adjacent and outside the score lines, Fig. 2 (not shown). The reduced areas of the score lines increase resistance of the removable portion to being torn out by means of a pull tab (see Division B8) riveted thereto.
