Abstract: A half-size sheet metal steam table tray and a lid that may be joined by a sealed double seam to the tray to form a container for packing or canning, processing, storing, shipping, distributing, heating, displaying and serving processed food products in any desired manner, and particularly for use at a steam table. The tray and lid container is desirable for institutional use to replace 105 fluid ounce capacity No. 10 cans for processed foods or frozen food containers. The tray serves as a cooking vessel suitable for heating the food product packed therein after removal of the lid and before serving. The tray becomes a serving container replacing stainless steel serving pans commonly used in volume feeding establishments.

Abstract: A sheet metal pull tab for easy opening cans of the full panel pull-out type which has a special and coordinated configuration, shape and contour of pull-ring, keyhole-shaped slot, nose and nose-forming walls which serve readily without tab failure to rupture the score line formed in a can end for removal of an end panel defined by the score line. The new pull tab structure imparts unusual overall strength to the pull tab that enables the pull tab either to provide greater strength when formed from the same gauge sheet metal or to provide the same strength when formed from lighter gauge sheet metal as compared with similar prior sheet metal pull tabs having the same outer contour; and also to provide such a pull tab structure which reduces the amount of metal, disregarding gauge, that is required to form the strong pull tab structure.

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.
