  Further, a recess is provided on the outer peripheral portion of the cover body 112 so as to go around the outer peripheral portion, and a release restricting portion is also configured by providing a convex stripe which goes around the inner peripheral portion on the inner peripheral portion of the housing recess 110 Also in the case where the cover body 112 of the initial form having the curved portion 112a is disposed so as to cover the accommodation recess 110 and plastically deformed so that the curved portion 112a becomes flat, The convex part of the accommodation recessed part 110 can be inserted, and it can be set as the cover body mounted state which is the state by which the accommodation recessed part 110 was sealed by the cover body 112. FIG.

  Also in this case, when plastic deformation is performed so that the curved portion 112 a of the cover body 112 is flat, movement of the end edge of the cover body 112 toward the bottom of the accommodation recess 110 (pressing the second metal body 102 Because movement in the direction is restricted by the movement restriction unit 141. It is convenient to plastically deform the curved portion 112 a so as to be flat.

  In addition, in the cooking container 100 of this embodiment, the cover body 112 provided with the recessed part or convex part in the outer peripheral part by plastically deforming so that the curved part 112a of the cover body 112 becomes flat, and the cooking container main body 101 The housing recess 110 can be made watertight by bringing it into close contact with the housing recess 110 provided with a recess or a projection on the inner peripheral portion (see FIG. 10). As a result, it is possible to prevent water and the like from infiltrating into the accommodation recess 110 of the cooking vessel main body 101, and it becomes possible to obtain a highly reliable cooking vessel provided with a temperature detection unit.

  By the way, if the cover body and the cooking vessel main body do not have a configuration in which the cover body and the cooking vessel main body adhere in a watertight manner by plastic deformation so that the curved portion becomes flat, from between the cover body and the cooking vessel main body Although it is necessary to seal using a seal member so that water does not infiltrate into the housing recess, this seal member needs to have considerable heat resistance (heat resistance comparable to that of the cooking container main body and cover body) On the other hand, in the cooking container of the said embodiment, such a sealing member is unnecessary and the deterioration of the performance by the penetration of the water to the accommodation recessed part resulting from the heat-resistant deterioration etc. of a sealing member is suppressed.
