By the way, in the case of a transportable container which can be stacked, it may be good in some cases to form the supporting legs 8a to 9b at the corners in order to provide sufficient stability during stacking. . However, in the conventional transport container as described above, the wide pocket portions 8a, 9a
Must be formed at corners of narrower support legs 4a and 5a. For this reason, the support legs 4a,
In order to form as many corners 5a as necessary, the pocket 8
The width (opening width) of not only the formation positions of the a and 9a but also its width (opening width) must be considered, and the degree of freedom in design tends to be low.

In the conventional transport container, it is necessary to form relatively wide pockets 8a and 9a. Therefore, depending on the size of the contents, the contents are fitted into the pockets 8a and 9a. In some cases, the accommodation of the contents was reduced. Further, in the conventional container, when the same-shaped containers are overlapped with each other and the sliding operation is performed, the first side wall halves 11a and 11b of the upper container have narrower supporting legs 4a and 4b.
a falls into the narrow half-box pockets 15a, 14a formed in the first side wall halves 11a, 11b of the lower container, and cannot penetrate them. There was a problem of being restricted.

Similarly, the wide supporting legs 4b, 5b of the second side wall halves 12a, 12b of the upper container are formed on the second side wall halves 12a, 12b of the lower container. And fall into the wide half-box pockets 15b and 14b, and cannot get over them, so that there is a problem that the width in which the sliding operation can be performed is limited.

The present invention has been made in view of such circumstances, and allows nesting and stacking of same-shaped containers, and a sliding operation in a stacking state.
In addition to nesting and stacking half boxes that can nest and stack identical containers,
Furthermore, it is another object of the present invention to provide a transport container that has a good accommodation of contents, a degree of freedom in forming positions of the support legs and the pockets, and a large width in which a sliding operation is possible.
