PURPOSE: To surely prevent a high temperature steam from fiercely jetting out, and ensure container safety at a high level not only at the time of normal operation, but also in the case wherein an exothermic reaction happens due to an erroneous operation by a consumer other than the normal operation or dropping impact, etc., and the internal pressure of the reaction chamber ascends. CONSTITUTION: A container with heating function has a lid structure wherein steam which is generated by an exothermic chemical reaction can be easily released to the outside of the container. Then, for a lid 12, the periphery of the central part is cut into an arc-shape for one time, and then, at least one of both sides of the cut part is press-treated, and the central part side of the lid 12 and the peripheral part of the lid 12 are put together in such a manner that the central side may become upper, and the peripheral side may become lower, and the overlapped part is sealed with a repair rubber to form an arc- shaped sealed connecting part. Also, for a protective cap 15, a protuberance 15a for separation which presses a slightly external side of the arc-shaped sealed connecting part by a movement in the axial direction is formed on the lower surface side. |
