PURPOSE: A structure of a steamed container for improving tightness is provided to prevent the steamed container from melting by preventing the steamed container from directly contacted with the upper end of a steaming container. CONSTITUTION: A steamed container(10) is made of plastic and is semitransparent. A ring-shaped groove is formed at the bottom edge of an adhering unit(16) adhering closely to the upper end(2) of a steaming container(1) made of metal. A sealing ring(14) is made of silicon and is inserted into the groove. One part of the sealing ring protrudes from the groove so that the steamed container is directly not contacted with the upper end of the steaming container.
