ABSTRACT:
A metal container which can be utilized in a microwave oven has an interior and an exterior defined by a bottom and at least one side wall. Each side wall has a height which does not exceed 40 percent of the wavelength of the microwave radiation. The container is adapted to receive an object into its interior through an open top. Microwave-transparent electrical insulation is disposed on each side wall and on that part of the bottom which would, in the absence of insulation, contact the floor of the oven. This microwave transparent electrical insulation may be a coating on the metal, a label, or a sleeve placed around the container. A microwave transparent, electrically-insulating cap is removably disposed at the top of the container. The top of the container also may have a removable seal disposed thereon. Also, a method for storing an object, then subjecting the object to microwave radiation comprising first placing the object in the removably sealed metal container. The object then is stored in the container. To irradiate the object with microwaves, the seal is removed and the microwave-transparent, electrically-insulating cap is removably disposed over the opening. Then, the object and container are irradiated with microwave radiation for a time sufficient to heat the object. Further, a method for heating an object in the container of the invention by placing an object into the container, placing the insulating cover over the opening, and irradiating the object and the container with microwave radiation for a time sufficient to heat the object.
