<P>PROBLEM TO BE SOLVED: To provide a microwave oven adaptable container capable of relieving internal pressure generated by heating at a low cost, and preventing a packaging material from being ignited or scorched by the excessive application of a microwave. <P>SOLUTION: In the microwave oven adaptable container, a conductive printing ink or a coating agent 14 is applied to a contact place of a lid body 10 to be sealed to a container body 1 contacting with the container body, and a sealant layer in the vicinity of the printing ink or the coating agent is heated and melted by applying the microwave, and the internal pressure increased by heating is relieved. The printing ink or the coating agent is constituted by blending a substance having an electric resistance of ≤10<SP>-7</SP>Ωm and a substance having an electric resistance of ≥10<SP>4</SP>Ωm. A heat generating temperature is adjusted by a blend ratio, contact surfaces of the container body with the lid body are formed of three annular projections projected on the upper surface of the container body to adjust a heating capacity for melting the sealant layer necessary for relieving the internal pressure by setting widths of the annular projections. <P>COPYRIGHT: (C)2009,JPO&INPIT |
