ABSTRACT:
A metal container and system for arc-free use and minimal electromagnetic reflection in a microwave oven. The container has smooth wrinkle-free side and bottom walls and edges, with the side wall in elevation having a curved configuration provided with a generous radius. The configuration of the container in plan view is either round (circular) or has rounded corners formed with generous radii. The surfaces of the walls and edges are coated on both sides with a layer of heat-resistant plastic material having a thickness on the order of 0.25 to 2.5 mils. A heat-resistant plastic rigid microwave transparent lid is provided for the container, the lid having edge portions that cover the edges of the container when the lid is placed thereon. Such edge portions electrically insulate the metal container from the walls of a microwave oven while the lid itself serves to reduce the escape of heat and moisture from the container.
