The food container of the present invention comprises a box-shaped container body 1 having an open upper surface and a substantially flat cover plate 2 having a shape slightly smaller than the upper surface opening of the box-shaped container body 1. Although the shape of the box-shaped container body 1 in the present invention is not particularly limited, it is generally a regular octagonal column as shown in FIG. 1 or a rectangular parallelepiped as shown in FIG. In the present invention, the cover plate 2 generally has a shape smaller than the opening shape of the upper surface of the box-shaped container body 1 by about 0.5 to 2 mm over the entire circumference. It is preferable to provide a knob portion 8 on the upper surface of 2 so that the lid can be easily removed. However, the shape of the knob 8 is
The present invention is not limited to those shown in FIGS. In the food container of the present invention, the materials of the box-shaped container body 1 and the lid plate 2 are not particularly limited, and may be paper, wooden, or plastic. May be.

[0007] When the contents are put into the box-shaped container body 1 and the containers on which the lid plates 2 are placed are sequentially stacked on the bottom surface 3 of the box-shaped container body 1, the contents are located on the lower side. A projection 4 is provided which can push down the lid plate 2 of the container downward (see FIGS. 1 (b) and 2 (b)). In the food container of the present invention, when the containers containing the contents are sequentially stacked by the projections 4, the lid plate 2 of the container located on the lower side is pushed down, and the compressive load is applied to the contents from above. Therefore, after putting the contents in the container, it is possible to manufacture a pressed sushi simply by stacking the contents. FIG. 3 shows a state in which the contents 9 are put in the box-shaped container main body 1 of FIG. 2 and the containers are stacked, and the cross-sectional view shows that the contents 9 of the two lower containers are compressed. The state where a load is applied is shown.
