[Instructions for cooking containers]
An example of handling the cooking container 1 will be described with reference to FIG.

First, as shown in FIG. 5 (a), an intermediate dish body 3 containing a cooking object 6 is attached to a container body 2 into which an appropriate amount of water 5 has been charged, and a lid body is attached to the intermediate dish body 3 of the attached object. 4 is placed on an induction heating cooker 7. Next, when the induction heating cooker 7 is operated, the water 5 becomes steam due to the heat generated by the induction heating heating element 21 in the container body 2 described above, and the cooking object 5 in the inner dish 3 is steamed. During the cooking, the lid body 4 and the lid body 4 are detached from the middle dish body 3 by the fitting of the fitting portion 35 of the middle container 3 and the fitted portion 47 of the lid body 4. There is nothing. Further, during cooking, the steam is appropriately discharged from the exhaust hole 40 of the lid 4, so that the internal pressure of the intermediate dish 3 is stabilized.

  Then, after cooking is completed, the induction heating cooker 7 is stopped, and the lid 4 is removed from the middle dish 3 of the mounted body. At this time, as shown in FIG. 5B, when the knob 46 of the tension edge 44 of the lid 4 is picked and pulled outward of the opening of the intermediate dish 3, the tension edge 44 is moved in the outward direction. It is elastically deformed. At this time, due to the tension of the tension edge portion 44, the fitting state between the fitting portion 35 of the intermediate dish 3 of the mounted body and the fitted portion 47 of the lid 4 is loosened, as shown in FIG. In addition, hot air such as steam and steam in the cooking container 1 is preferentially ejected from the part where the fitting state is loosened, and the lid 4 is removed from the inner dish 3.

  As described above, according to the cooking container 1 described above, when removing the lid 4 from the middle dish 3 of the cooking container 1, even if hot air such as steam or steam blows out from the middle dish 3, the fingertip of the user Avoid contact with
