  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, a first embodiment of the present invention will be described with reference to FIGS.
1A is an exploded top view of the container according to the first embodiment of the present invention, FIG. 1B is a longitudinal sectional view of the container, and FIG. 2 is an enlarged longitudinal sectional view of the fitting portion of the container.
As shown in FIG. 1 (B), the container 10 includes a container body 20 and an upper lid 30. The container body 10 includes an upper body fitting portion 22 that extends upward. The upper lid fitting portion 32 extending upward is provided, and the main body fitting portion 22 and the upper lid fitting portion 32 are fitted together to integrate them.
The container body 20 and the upper lid 30 are respectively provided with fitting contact surfaces 24 and 38 that are vertically opposed to each other, and the body fitting portion 22 and the upper lid that extend upward from the outer peripheral side ends of the respective fitting contact surfaces. The fitting portion 32 is provided with a concave portion 26 and a convex portion 39, respectively, a convex portion 26 ′ is provided on the concave portion 26, and a concave portion 39 ′ is provided on the convex portion 39 ( (See FIG. 2).
By fitting the convex portion 39 with the concave portion 26 and the convex portion 26 ′ with the concave portion 39 ′, the convex portion 39 is prevented from coming off by the convex portion 26 ′, so that the container body 20 and the upper lid 30 are not detached. Yes.
The fitting contact surfaces 24 and 38 are flat over the entire circumference.

The upper lid 30 has a circumferential groove 36 on the inner periphery of the outer periphery, and a tongue piece 34 is provided on the fitting contact surface 38 of the upper lid fitting portion 32. The shape of the tongue piece 34 is not limited to the illustrated shape, and may be a horseshoe shape, a circular shape, an elliptical shape, or two or more.
When the steam pressure in the container body 20 rises above a certain level during cooking by a microwave oven, the upper lid 30 is pushed up and the tongue piece 34 is opened upward, so that steam is discharged from the bottom of the groove 36.
In this way, since the pressure of the vapor in the container can be adjusted, the upper lid will not come off even if the sealed container is heated by microwaves using a microwave oven.

In the conventional microwave cooking container, when the upper lid is pushed up, the steam is discharged from the vent and the broth also jumps up. However, in the container 10 of the present invention, as shown in FIG. Since it only jumps out from the periphery of the tongue piece 34 to the oblique side, it is possible to prevent the broth from splashing out of the container 10.
In this case, if the tongue piece 34 has a structure in which the outer peripheral side of the upper lid 30 is fixed and the center side is opened, it is possible to guide the squirting of the broth inward and prevent it from scattering out of the container 10. In addition, when the upper lid 30 is opened after cooking, the finger can be prevented from touching the heated steam.
