Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to an inner pot for conditioning provided with a heat-insulating container and a conditioning pot contained inside the heat-insulating container, and the inner pot will be heated. Conditioned or semi-conditioned conditioners are adiabatic conditioners that use heat insulation or residual heat for additional conditioning in insulated containers. [Prior Art] An example of a conventional adiabatic conditioner is, for example, the adiabatic conditioner disclosed in the Japanese Patent No. 4-2 8 4 91. The heat insulation conditioner is composed of a heat insulation container with a double structure, an outer cover covering the heat insulation container, an inner pot accommodated in the heat insulation container, and a pot cover covering the inner pot. The inner pot of the food in the state is stored in a heat-insulating container, and the outer lid is sealed. The heat of the inner pot and the food is kept in the heat-insulating container, and it can be adjusted without using fire. A pair of handles are provided in the inner pot, each handle has a raised portion extending upward from the inner pot and a supporting portion protruding outward from the top end of the raised portion to form an inverted L-shaped cross section, and the supporting portion and the The grip part on the outer end of the supporting part is carried between the heat-insulating container and the handle of the outer cover, so that the entire inner pot is contained in the heat-insulating container. Problems to be Solved by the Invention However, in the case of the so-called pot dishes such as tofu pot, black wheel, Japanese stew pot, assorted hot pot, etc. in the inner pot, the heat-insulating container with the inner pot needs to be set directly on the dining table Top, and then eat the conditioner directly from the inner pot. In addition, in order to improve the heat insulation of the inner pot and the food, the inner pot is hung from the lower end of the inverted L-shaped handle and is stored in the deep part of the heat-insulated container.

Management The first edge portion 8 d of the gas sealing member 6 is insulated even when it is insulated. In the case where the center of = 3 is offset, it corresponds to the internal device 2 and the internal curve, so that the gap 9 between the two is always kept in a sealed shape. In addition, in the state of removing the cover from the table and eating the conditioning product, it is also difficult to make the cold part of the product, and the conditioning product can be consumed at an appropriate temperature as much as possible. _By using an earthenware pot that is pottery as the inner pot 3, it can maintain the adjusted temperature for a long time and well due to its low heat conductivity. Furthermore, the gas sealing member 6 is provided so that it can be freely installed. Since the gas sealing member 6 can be easily removed from the heat-insulating container 2 for cleaning or cooling, it is not only good in hygiene but also convenient in replacement. 'Futian uses rigid body 7 in combination with gas seal member 6, even if inner steel 3 is used.
