[0028]

Since the present invention is constructed as described above, it has the following effects.

On the flip-up side wall, a vertically elongated outer narrow groove is formed symmetrically with the vertically elongated inner narrow groove sandwiching the vertical center line, and the inner partition and the outer side are formed on the inner partition member. A mounting protrusion that is inserted into the narrow groove is formed, and an engaging tongue is formed on the mounting protrusion, and the mounting protrusion and the engaging tongue allow the inner narrow groove and the outer narrow groove of the splashed sidewall to be formed. Since the part located between them is sandwiched, the strength of the flip-up side wall, and by extension, the strength of the folding container, are greatly reduced compared to the conventional folding container in which the flip-up side wall has a complicated and large notch. In addition, since the partition member is firmly attached to the splashed side wall, the partition member does not come off from the splashed side wall or float up from the splashed side wall.

The mounting projection formed on the partition member has a narrower space than the height of the mounting projection of the partition member, and the inclined surfaces of the upper and lower inclined portions of the outer narrow groove formed in the flip-up side wall. Since it is configured to come into contact with and to be elastically deformed, the mounting protrusion of the middle partition member is firmly inserted into the outer narrow groove, and therefore the movement amount of the middle partition member with respect to the splashed side wall. Therefore, it is possible to reduce the movement of the articles accommodated in the accommodation space of the intermediate partition member, and it is possible to easily prevent the intermediate partition member from coming off from the splashed side wall.
