DESCRIPTION OF THE PREFERRED EMBODIMENTS A heating cooking container according to an embodiment of the present invention will be described with reference to the drawings. [First Embodiment] As shown in FIGS. 1 to 6, a flat lid member 2 is combined with a heat-resistant container body 1 made of polypropylene or the like. In addition, it is preferable to use a material in which paper material is laminated on the surface layer and PET is laminated on the innermost layer, for example, in consideration of heat resistance and hygiene so as to prevent curling due to heat vapor or the like. . The container body 1 is a rectangular parallelepiped with an open top, and a flange 6 is provided around an upper end.
Is provided. Around the flange 6, the container body 1
Is provided with a hanging portion 7 for increasing the rigidity. The bottom portion 10 has a central recess 1 having a height of about 5 mm to prevent the central portion from bending due to the weight of the contents during heating.
2 are formed, and leg portions 16 having the same height as the central concave portion 12 are formed at the four corners. By providing such legs, the contents can be uniformly heated even when cooking with a microwave oven. A plurality of vertical ribs 24, 26 are provided on the long side surface portion 20 and the short side surface portion 22, respectively. The vertical rib 26 of the short side surface 22 extends to the positioning rib 30 (pressing projection) on the flange 6. As a result, even if the container is heated by the microwave oven and becomes flexible, the strength of the positioning ribs (projections) of the flanges is maintained. Can be taken out of the range without fail. At the boundary between the vertical rib 26 and the positioning rib 30, a fixing recess 32 for receiving the lid member 2 is provided. An upper portion between the long side surface portion 20 and the short side surface portion 22 is provided with a stacking shoulder portion 34 for facilitating removal when the same containers are stacked.

The cover member 2 has an outer shape substantially matching the outer periphery of the flange 6, and a plurality of cuts 40 are provided in a portion corresponding to the position of the short side surface portion 22. The distance between the opposing cuts 40 is slightly larger than the distance between the bottoms of the opposing fixing recesses 32, for example, by 0.7 mm.
The lid member 2 mounted on the container body 2 is fixed to the container body 1 by a fixing recess 32. The cover member 2 is provided with a folding line 48 for forming a vapor escape port 46 near the long side surface portion 20. It is desirable that the size of the steam escape port 46 occupies 10% or more of the container opening area.

The method of using the cooking container of the first embodiment will be described. After filling the container body 1 with the contents, the container body 1 is closed by the lid member 2. At this time, the notch 40 of the lid member 2 is engaged with the positioning rib 30 to facilitate the positioning of both, and the innermost part of the notch 40 is engaged with the fixing recess 32 so that the lid member 2
Is fixed to the container body 1. Thereafter, if desired, the entire container is shrink-wrapped. In the heating cooking, the shrink wrapping is discarded, the lid member 2 is removed from the container body 1, and the contents, that is, food ingredients are mixed and liquid is injected, and the lid is closed again. Also at this time, the notch 40 of the lid member 2 is engaged with the positioning rib 30 to facilitate positioning of both, and the innermost portion of the notch 40 is engaged with the fixing recess 32 so that the lid member 2 is fixed to the container body 1. In particular, when the container is transported or rotated for heating, the temporary fixing in which the innermost portion of the notch 40 engages with the fixing recess 32 and the lid member 2 is fixed to the container body 1 is very difficult. It is convenient. After cooking
Positioning rib 3 corresponding to short side surface portion 22 of flange 6
Hold 0 with your finger and remove from microwave. Since the rib 30 is less likely to feel heat than the flat flange portion and has excellent strength, the container after heating and cooking can be reliably taken out of the microwave oven.
