The inner pot 3 and the lid 4 covering the inner pot 3 are formed. The heat-insulating container 2 has a double-insulation structure in which a stainless steel outer plate 2 a and an inner plate 2 b are joined to each other to form a pot shape, and a vacuum heat-insulating layer 5 is formed between the outer plate 2 a and the inner plate 2 b. A ring-shaped gas sealing member 6 capable of being attached and detached freely is embedded in the continuous peripheral large-diameter stepped portion 2 c and the small-diameter stepped portion 2 d which are opened on the upper portion of the inner plate 2 a. The inner pot 3 and the lid 4 use a so-called ceramic earthen pot having a lower thermal conductivity than metal. The body portion 3 a of the inner pot 3 is similar in shape and slightly smaller in size than the inner plate 2 a of the heat-insulating container 2 and the body portion 3 a of the inner pot 3 A stepped portion 3 b having a diameter approximately the same as the opening of the upper portion of the heat insulation container 2 is connected to the upper outer periphery.

In addition, the second edge portion 8 e contacts the peripheral wall 2 g of the small-diameter stepped portion 2 d, and the gas seal blocks the upper and lower sides of the second edge portion 8 e, so that the temperature of the inner pot 3 and the conditioning product can be maintained for a longer time. . In addition, in the case where the conditioning products in the inner pot are so-called pot dishes such as tofu pot, black round, Japanese stew pot, assorted hot pot, etc., they are heated on a cooker and delivered to the dining table. In order to maintain the warmth of the conditioning product, The inner pot 3 is housed in a heat-insulating container 2. In this case, the conditioning product can be eaten directly from the inner pot 3. Since the step portion 3b on the upper side of the body portion 3a of the inner pot 3 is directly supported by the gas sealing member 6 opened at the upper portion of the heat insulation container 2, the inner pot The whole of 3 will be located above the thermally insulated container 2. As a result, at the dining table, the already seated person can easily see the conditioning product of the inner pot 3 while still sitting, and can take the conditioning product without changing the sitting condition. Even if the first edge portion 8d of the gas sealing member 6 is offset from the center of the heat-insulating container 2 and the inner pot 3, it will be bent corresponding to the contact with the inner pot 3, so that the gap 9 between the two is often Keep sealed. Furthermore, it is difficult to cool the conditioning product in a state where the outer cover is removed from the table and the conditioning product is consumed, and the conditioning product can be consumed at an appropriate temperature as much as possible. By using an earthenware pot made of pottery as the inner pot 3, since it has a high heat storage property and a low thermal conductivity, the temperature of the conditioning product can be maintained well for a long time. Moreover, the gas sealing member 6 is provided so that it can be freely
