초록 ▼

An embossed can end construction for full opening, easy opening metal cans used for food products that are heat-processed in the closed cans. The can end has an embossed formation in the removable panel of the can end defined by an endless generally annular score line, either with or without a protective fold at the peripheral edge of the removed panel. A ring pull tab is riveted to the removable panel portion having a nose with an offset tip which engages the can end adjacent the score line to initiate rupture of the can end at the score line when the ring of the tab is raised and the nose tip moves down. The embossed formation has a general modified heart-shape in contour with a depressed groove defining the heart-shape. The embossed formation imparts great stiffness to the can end metal. The stiffness maintains a planar shape for the can end which resists doming or bulging when the end is subjected to pressure inside the can different than atmospheric pressure. The planar stiffness imparted by the embossed formation assists in directing the initial rupturing force of the cooperating pull ring nose tip substantially vertically, that is parallel with the axis of the can and the axis of the riveted connection between the pull ring and can end. The stiffness also prevents curling of the removable panel as the panel is completely pulled away from the can by the final lifting of the pull ring from the can.

대표청구항 ▼

Easy opening can end construction for a full opening can including a metal can end member having a seam flange and a recessed corner below the seam flange; an end member wall extending from said corner having a removable panel portion defined by an endless main score line located adjacent said corner; removal of said panel portion from said wall providing a full opening for a can to which the end member is seamed by said seam flange; a ring pull tab having a ring end and an offset nose tip at its other end; rivet means connecting the pull tab intermediate its ends to the panel portion; the nose tip normally being located adjacent the main score line for initiating shear score line rupture upon pulling the ring end of the pull tab away from said wall; an endless heart-shaped groove formation embossed downward in said panel portion symmetrical about a line passing through the center of the end member, tHe center of the rivet means, and the nose tip; and means controlling initial and final bending of adjacent flap areas of the removable panel portion into the can along spaced bend zones extending perpendicular to said line; said spaced bend zones being located, respectively, outside and inside the rivet means relative to the can end center, and said spaced bend zones both being located outside said embossed groove formation.
