A recessed portion 1a1 is formed from the tip of the elastic locking tongue 5 formed on the inner side 3 of the short side wall 3, the inside and the upper part of which is open, into which the protruding portion 5a projecting inward beyond the inner surface 3a can be inserted. . In the above-mentioned conventional folding container, as shown in FIGS. 5 and 7, when the folding container is folded, it is formed on the short side wall 3. As shown in FIG. Since the concave portion 1a1 into which the protrusion 5a of the elastic locking tongue 5 can be inserted is formed in the long side bank portion 1a of the bottom portion 1, the folding container becomes a box as shown in FIG. When assembled into a mold, FIGS. 4 and 7
As shown in the figure, the concave portion 1a1 is exposed on the inner surface 1a2 side of the long side bank portion 1a of the bottom portion 1, and the accommodated articles can enter or be accommodated in the concave portion 1a1. When taking out, there is a problem that the article is caught on the lower end surface 2d of the long side wall 2 located above the concave portion 1a1, and the workability of taking out the article is deteriorated. An object of the present invention is to solve the problems of the above-mentioned conventional folding container. In order to achieve the above-mentioned object, the present invention has a bottom and four side walls hinged to the bottom and folds such that the side walls overlap the bottom. In a foldable container where
A recess is formed at the bottom of the side wall that is formed first and into which the elastic locking tongue can be inserted, and a hanging insertion piece that can be inserted into the recess is provided at the side wall that is raised later. is there. Embodiments of the present invention will be described below, but the present invention is not limited to these embodiments unless it departs from the gist of the present invention. Note that the same reference numerals are used for the same components as those of the above-described conventional folding container, and detailed description thereof is omitted. Reference numeral 7 denotes a plate-shaped hanging insertion piece which is vertically provided from a lower end face 2d of the long side wall 2, and an inner surface 7a of the hanging insertion piece 7.
Are formed substantially flush with the inner surface 2 c of the long side wall 2. When the folding container is assembled in a box shape, the hanging insertion piece 7 is provided with an elastic locking tongue piece 5 formed on the short side wall 3.
Is inserted into a concave portion 1a1 formed in the long side bank 1a of the bottom portion 1 into which the projecting portion 5a is inserted. The above-described hanging insertion piece 7 has a front shape (a shape viewed from the long side bank 1a side) corresponding to a front shape (a long side) of the concave portion 1a1 formed in the long side bank 1a of the bottom 1. (The shape viewed from the side bank portion 1a side), and the size thereof is also formed to be substantially the same size. Therefore, the folding container is assembled in a box shape, and the plate-shaped hanging insertion piece 7 suspended from the lower end surface 2 d of the long side wall 2.
Is a recess 1a1 formed in the long side bank 1a of the bottom 1
When inserted into the recess 1a1, the recess 1a1 is substantially shielded by the hanging insert 7 so that the inner surface 2c of the long side wall 2 and the inner surface 7a and the inner surface 1a2 of the hanging insert 7 are substantially flush. It is configured. As described above, the folding container is
As shown in FIG. 1, when assembled in a box shape,
A plate-shaped hanging insertion piece 7 hanging from the lower end face 2d of the long side wall 2 projects from an elastic locking tongue piece 5 formed on the short side wall 3 formed on the long side bank 1a of the bottom 1. Since the portion 5a is inserted into the insertable concave portion 1a1 and is configured to shield the concave portion 1a1, the concave portion 1a1 formed in the long side bank portion 1a of the bottom portion 1 is connected to the long side bank portion of the bottom portion 1. There is no exposure to the inner surface 1a2 side of 1a, so that the articles stored in the folding container do not enter into the concave portion 1a1 formed in the long side bank 1a of the bottom 1. Further, since the hanging insertion piece 7 is suspended from the lower end surface 2d of the long side wall 2, the long side bank 1a of the bottom 1 is provided like a conventional box-shaped folded container. Since there is no eaves portion formed by the lower end surface 2d of the long side wall 2 above the concave portion 1a1 formed at the bottom, when the stored articles are taken out, as in the conventional folding container, the articles are moved to the bottom 1 Can be solved by catching on the lower end surface 2d of the long side wall 2 located above the recessed portion 1a1 formed in the long side bank 1a. In the embodiment described above, the long side wall 2 is hingedly connected to the lower bank portion 1a of the bottom 1 opposite to the lower wall.
Although a folding container is shown in which the short side wall 3 is hinged to the opposite high bank 1b, the short side 3 is hinged to the low opposite bank 1a of the bottom 1 as a matter of course. The present invention can also be applied to a folding container in which the long side wall 2 is hingedly connected to the opposite high bank portion 1b. In this case, the elastic locking tongue 5 is formed on the long side wall 2, and the concave portion 1 a 1 into which the protruding portion 5 a of the elastic locking tongue 5 is inserted is a bank with a relatively low height of the bottom 1. It will be formed in the part 1a. Since the present invention has the above-described configuration, the following effects can be obtained. A recess is formed in the bottom portion of the side wall that is formed first and into which the elastic locking tongue can be inserted, and a hanging insertion piece that can be inserted in the recess is provided in the side wall that is formed later. Therefore, it is possible to prevent the articles stored in the folding container from entering the recess formed in the bottom.
