A thermally insulated vessel for cooking, serving, and storing of foods and beverages, particularly adapted for use in microwave cooking units. A double-walled vessel is provided, including an outer container and a removable inner container, both having substantially similar shapes. The inner container is supported by a grooved flange extending outward from its upper rim which rests on the upper rim of the outer container. The inner container and the outer container are separated by a narrow gap, forming an enclosed air cavity. The flange groove and rim are designed to allow air to escape from the cavity to relieve the pressure caused by hot foods or beverages in the vessel, and to resist air and liquid flow into the cavity as the vessel cools. A raised lid is further provided, fitting over the inner container, and having a flat top and a recessed handle, to allow several vessels to be stacked on each other for cooking or storing.

A microwave cooking vessel comprising: an outer container having a plastic floor and plastic walls; an upper rim forming the upper periphery of said outer container, said upper rim being beveled; at least one handle extending outwardly from said outer container at a point below said upper rim; an inner container having a plastic floor and plastic walls; a flange extending outwardly from and circumscribing the upper periphery of said inner container, said flange including a groove having a shape corresponding to said rim; said rim frictionally engaging said groove so that said inner container is removably supported within said outer container to define a fluid containing cavity between the floor and walls of said inner container and the floor and walls of said outer container; and said groove and said upper rim cooperating by relative movement therebetween to provide valve means for allowing fluid to escape from said cavity whereby said groove defining flange moves upwardly to disengage said upper rim from said groove when said fluid containing cavity is heated, and said groove defining flange moves downwardly to sealingly engage said upper rim when said cavity is cooled.
