Abstract
Abstract This invention provides a container (11) for use in containing a material (12) to be heated in a microwave oven, which container (11) is capable of preventing locally occurring over-heating, and of allowing its contents (12) to be uniformly and effectively heated. The container (11) comprises a container proper, a lid (16) and a microwave shielding layer (15), the shielding layer (15) being disposed at least at the position (14), through the intermediary of an air layer, where the upper surface of the material (12) contacts the side surface of the container proper (13), i.e., is disposed on the portion (17) of the lid which overhangs the side wall of the container proper (13).
