Abstract
A multi-part container for use in a microwave including two sealed compartments for containing complementary foods subjected to different treatment prior to preparation by the consumer. A bottom portion includes a sealed opening defining a first interior region for housing first contents to be subjected to sterilization. An upper part includes a second sealed opening defining a second interior region for housing second contents not benefited from high temperature treatment. The bottom portion and upper part are sealed together to form a single multi-part container. Prior to preparation by the consumer, the first and second interior regions are each opened by the consumer and combined within the interior region of the bottom portion. The upper part is replaced on the bottom portion to form an overcap for the interior region for heating in a microwave.
