成されている。As shown in FIG. 7, these folding containers can be rotated by a frame 1, a bottom plate 2, a plate-shaped portion 4 rotatably attached to the frame 1 by a shaft 7, and a shaft 8 by the bottom plate 2. To the frame 1 and two shafts 10 connected to the frame 1 so that they can be bent at a connecting portion 6.
It is composed of two sets of tilt plates 9 which are rotatably attached.

利である。Also, first fold down the swing plate 10 and then the side plate 3 in the empty container.
It can be folded by bending from the connecting portion 6 of. And in the folded state, it is extremely thin and very convenient for storing the container.
このような折りたたみコンテナーは、折れ曲がり部分を
数多く有するために外力に対し若干問題を有している。Since such a folding container has many bent portions, it has some problems against external force.

外れてしまう。Further, the conventional example shown in FIG. 8 is actually a tenth type so that the recessed portion 4a formed in the connecting portion 6 between the plate-shaped portions 4 and 5 and the hook-shaped projection 5a can be smoothly fitted. It is formed as shown in the figure. That is, the joint surface between the two forms an arc surface around the pivot axis of the hinge. Therefore, it has a drawback that it can be easily removed by an external force in the direction of the arrow. Especially when the side plate is made of a thin plate, it comes off very easily.

The upper plate-like portion and the lower plate-like portion that is rotatably attached to the bottom plate are connected to each other so that they can be bent at the connecting portion, and the side plate is rotatably attached to the frame. It is composed of a swing plate, and at the connecting portion of the upper and lower plate-like portions, a concave portion is provided on one plate-like portion and a plate-like protruding portion having a thinner wall thickness than the plate-like portion is provided on the other plate-like portion. The recess and the protrusion are formed so as to be fitted to each other, and the recess has a protrusion having the same thickness as the plate-like portion, and the protrusion has a penetrating portion into which the protrusion is fitted.

自在となったものである。[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In each of the embodiments of the present invention described above, the structure of the entire container is the same as the conventional example, as shown in FIG.
3. It is composed of a tilt plate 10 etc. and can be assembled and folded freely.

る。FIG. 1 shows the essential parts of a first embodiment of the present invention. That is, in the first embodiment, the folding container described above is provided with the reinforcing recessed portion 11 and the protruding portion 12 in the connecting portion 6 of the upper and lower plate-like portions 4 and 5 of the side plate 3, respectively. The structure is as shown in FIG.
第１図において、11は上側の板状部分４又は下側の板状
部分５に形成された凹部でこの凹部11中には適宜大きさ
形状でその高さが凹部11の深さにほぼ等しい突起13が形

より伸びて形成されている。これらの突出部12には前記
の突起13が丁度嵌合される貫通孔14が形成されている。In FIG. 1, reference numeral 11 denotes a recess formed in the upper plate-shaped portion 4 or the lower plate-shaped portion 5, and the recess 11 has an appropriate size and its height is substantially equal to the depth of the recess 11. The protrusion 13 is formed. Further, thin projections 12 which fit into the recesses 11 are respectively provided at positions corresponding to the recesses 11 of the lower plate-like portion 5 or the upper plate-like portion 4 and the end faces 4a or 5a of the plate-like portions 4 or 5, respectively.
It is formed to extend more. A through hole 14 into which the above-mentioned protrusion 13 is just fitted is formed in these protrusions 12.

14とが嵌合される。Since the convex portions and the protruding portions are formed on both of the plate-shaped portions 4 and 5 of the side plate, the container is assembled and the side plate is upright with respect to the bottom plate as shown in the sectional view of FIG. In, the concave portion 11 formed in the upper plate-shaped portion 4 or the lower plate-shaped portion 5 and the protrusion 12 formed in the lower plate-shaped portion 5 or the upper plate-shaped portion 4 are respectively fitted. At the same time, the fitting protrusion 13 formed in the concave portion 11 and the penetrating portion formed in the protruding portion 12
14 and are fitted.
このように側板の両板状部分は連結部分において、同一
箇所で二重に嵌合されるので、組立てられたコンテナー
に荷物を収納して持ち上げた際に荷重によってそったり
横ずれをおこしても嵌合部分が簡単には外れない。In this way, since both plate-shaped parts of the side plates are double fitted at the same position in the connecting part, even if the load is accommodated in the assembled container and lifted, it is fitted even if it warps or laterally shifts. The mating part does not come off easily.
第３図は本考案の第２の実施例の要部を示す図であり、
又第４図はその断面図を示している。FIG. 3 is a view showing a main part of a second embodiment of the present invention,
Further, FIG. 4 shows a sectional view thereof.

おそれをなくしたものである。更にこの実施例において
は、凹部と突出部が一層外れにくくなっている。In the second embodiment, the shape of the protrusion 15 is different from that of the first embodiment. That is, the tip portion A of the protruding portion is notched so that the portion B in FIG. 1 is not broken. Further, in this embodiment, the concave portion and the protruding portion are more difficult to come off.
第５図，第６図は、夫々第３の実施例を示す図である。5 and 6 are diagrams showing a third embodiment, respectively.

接合部分であるウエルドラインは、他の部分に比較して
強度的に弱い。The portion B in FIG. 1 is relatively easily damaged. When the container is molded with a synthetic resin as a material by an injection molding method or the like, a weld line is generated at the portion B. In other words, the molten resins that have flowed in from both sides at the time of molding merge at this portion B and are solidified together. Therefore, generally, the weld line, which is this joining portion, is weaker in strength than other portions.

なくなる。The third embodiment is an embodiment in which this drawback is resolved. That is, as shown in the sectional view of FIG. 5, the protrusion 12 has a shape in which the inner portion of the through portion 14 of the protrusion 12 is closed,
The closing portion 16 is provided so as to extend inward from the inner surface of the plate-shaped portion 4 or 5. As a result, not only the above-mentioned portion B but also the entire protruding portion 12 is reinforced. Furthermore the first
In the second embodiment, the fitting protrusion may project to the inside of the plate-shaped portion, but in this embodiment, the closing portion
Since it is covered by 16, there is no risk of damaging the contents.

とはない。In each of the embodiments of the present invention, for example, the fitting of the plate-shaped portion 4 and the plate-shaped portion 5 by the projection 13 of the concave portion and the through hole 14 of the through projection is
It becomes as shown in FIG. Therefore, if the inner surface of the through hole 14 is an inclined surface along a circular arc whose radius is the length up to the corner above the tip of the protrusion 13 with the axis of the hinge as the center, both can be fitted. After fitting, if the tip of the projecting portion 13 is slightly projected from the through hole 14, it will not come off easily.

Since they are fitted in a state of being pierced through, they do not easily come off due to warping or lateral displacement of this portion, and the connecting portion of the side plate is reinforced more reliably.
