DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

As clearly shown in FIG. 1, a packaging container according to the present invention comprises a container body 1 for storing vegetables, and a lid 2 which is separate from the container body 1 and covers the container body 1. In each case, for example, polystyrene,
It is a vacuum or pressure-formed product of a stretched synthetic resin film or sheet such as polypropylene or vinyl chloride.

A flange 7 extends outward from the upper edge of the container body 1. A small wall portion 8 bulges upward on the flange portion 7. The small wall portion 8 fits with the side wall portion 9 when the lid 2 is put on the container main body 1. The small wall portion 8 is formed continuously over the long side and the left and right short sides at the back of the container body 1 in FIG. 1, but is separated by the discontinuous portion 10 on the long side at the front. It has become.

A rib 5 bulging outward is formed on the side wall 3 and the bottom plate 4 of the container body 1 for reinforcement. In particular, the ribs 5 formed on the bottom plate portion 4 serve not only as reinforcement but also as slip prevention. Further, two flat portions 6 on which the ribs 5 are not formed are left in a part of the bottom plate portion 4. The flat portion 6 is a portion where the suction cup of the automatic packaging device is sucked when the present packaging container is put on the automatic packaging device.

On the other hand, as described above, the lid 2 is
Is a separate member, which is put on the container body 1 to cover it. As described above, the side wall 9 of the lid 2 fits with the small wall 8 of the container main body 1 when it is put on the container main body 1, and the height thereof is the same as that of the small wall. 8 lower than the height. That is, when the lid 2 is put on the container body 1, the side wall 9 is lower than the small wall 8, so that the discontinuous portion 10 of the small wall 8 becomes the side wall of the lid 2 as shown in FIG. Part of the container body 1 is exposed without being covered by the portion 8, and the ventilation into the container body 1 is secured through the exposed discontinuous portion 10.

[0012] The packaging container according to the present invention, as described above,
The container body 1 and the lid 2 are separate bodies, and a flat part 6 for adsorbing the suction part of the automatic packaging device is provided on a part of the bottom plate part 4.
