The structure is the same as that of a conventional pressure cooker in that the engaging piece 6 and the locking piece 8 are engaged with each other by rotational displacement, and the main container 1 and the lid 3 are sealed together via the caliper seal 11. be.

The dish 12 of the dish 12 is made of a conductive material such as aluminum, and by reflecting the high frequency waves of the microwave oven on the dish 2, the dish 12 reflects the microwave oven's high frequency waves to the opening 2 of the contents stored in the main container 1. It also functions to prevent localized overheating of the surface area and eliminate uneven heating. In addition, the lid body 3
If it is made of a conductive material such as aluminum, it is possible to prevent local overheating and eliminate uneven heating even without using the dish 12.

On the other hand, the pressure regulating valve 9 has a valve main body 1 as shown in FIG.
At least one of the valve body 13 and the spigot cap 14 is made of a dielectric material, and when the weight cap 14 moves up and down at high pressure and repeatedly contacts and separates from the valve body 13, the valve body 13 and the spigot cap 14 come into contact with each other. It has a structure that prevents discharge from occurring at certain points.

The handle 15 attached to the lid body 3 has a structure that can be folded downward so that it does not get in the way when the lid body 3 is put into the microwave oven. The handle 15 is made of a dielectric material like the main container 1, and has a long hole 16 extending in the longitudinal direction.
As clearly shown in FIGS. 3 and 4, the tip portion is attached to a bracket 17 connected to the lid body 3 via a pivot pin 18 so as to be rotatable downward. , and a movable piece 19 is provided at a position near the pivot pin 18, passing through the handle 15 in the lateral direction and attached so as to be movable in the lateral direction within a certain range. The movable piece 19 has a locking pawl 20 and an operating tongue piece 21 at one protruding end, and a push spring 2
