Abstract: 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.
