  The front side surface forming member 11 is made of corrugated cardboard plastic as shown in FIG. 2a. When assembled, the front side surface forming member 11 has a rectangular first central surface 11a that forms the front surface of the folding container 100, and the first central surface. 11a, each having a front side left side surface 11b forming a part of the left side surface formed so as to be bendable by a bent portion 14, and a front side right side surface 11c forming a part of the right side surface, It is formed in a letter shape so that it can be folded in three. The front-side left side surface 11b includes a notch portion 11f in which a portion that becomes a lower side when assembled is partially cut out. Further, the front side right side surface 11c forms a rectangular parallelepiped. The width α of the front side left side surface 11b and the width γ of the front side right side surface are formed shorter than the width β of the first central surface 11a. Further, the width α of the front side left side surface 11b is formed longer than the width γ of the front side right side surface 11c. Further, the lower width δ of the front left side surface 11b is formed to be the same length or slightly longer than the width γ of the front side right side surface 11c.

  The back side surface forming member 12 is made of corrugated plastic as shown in FIG. 2b. When assembled, the back side surface forming member 12 has a rectangular second central surface 12a that forms the back surface of the folding container 100, and the second central surface. 12a, each of which has a back side left side surface 12c forming a part of the left side surface formed so as to be bendable by a bending part 14, and a back side right side surface 12b forming a part of the right side surface. It is formed in a letter shape so that it can be folded in three. The back side right side surface 12b is provided with a notch portion 12f in which a part that becomes the lower side when assembled is cut out. The back side left side surface 12c has a rectangular parallelepiped shape. The width α ′ of the back side right side surface 12b and the width γ ′ of the back side left side surface 12c are formed shorter than the width β ′ of the second center surface 12a.

Further, the lower width δ 'of the back side right side surface 12b is formed to be the same length or slightly longer than the width γ' of the back side left side surface 12c.

  As shown in FIG. 1, the bottom sheet 50 may be made of any material as long as it is made of a flexible material. For example, plastic, cloth or paper is used. It is preferable to use a soft but low stretchable material.

  The front side surface forming member 11 and the back side surface forming member 12 thus manufactured form an enclosure member as follows. First, as shown in FIG. 3, the front side surface forming member 11 and the back side surface forming member 12 are tri-folded into a U-shape. Then, the front side left side surface 11b is overlapped so as to be disposed inside the back side left side surface 12c, and the front side right side surface 11c is overlapped so as to be disposed outside the back side right side surface 12b. After that, the end 12d of the back side left side 12c or the vicinity of the end 12d is connected to the outer side of the front side left side 11b so that the back side left side 12c and the front side left side 11b can be bent. On the other hand, the end portion 11d of the front side right side surface 11c or the vicinity of the end portion 11d is connected to the outer surface of the back side right side surface 12b so that the front side right side surface 11c and the front side left side surface 11b can be bent. As a connecting method, as shown in FIG. 4a, it may be affixed with a sheet-like adhesive tape, or as shown in FIG. 4b, an attachment margin 13 is provided at the end 12d of the rear left side surface 12c, and this attachment is performed. The margin 13 and the outer surface of the left side surface 11b on the front side may be glued together or fixed with staples. In short, any means may be used as long as the left and right side surfaces on the front side and the left and right side surfaces on the back side are connected so as to be bendable.

  Thus, as shown in FIG. 1, the front surface 10 is formed by the first central surface 11a, the back surface 20 is formed by the second central surface 12a, and the left side surface 30 is formed by the front-side left side surface 11b and the back-side left side surface 12c. The right side surface 40 is formed by the front side right side surface 11c and the back side right side surface 12b, and an enclosure-like member is formed. A bottom sheet 50 is attached to the bottom surface side of the enclosure-shaped member thus manufactured to form the bottom surface, and the folding container 100 is obtained.

  As shown in FIG. 5, the folding container 100 manufactured in this way has a left connecting portion 14a where the back side left side surface 12c and the front side left side surface 11b are connected to bend, and the left side surface 30 is connected to the left side. The portion 14a can be bent and bent inward. A part of the left side surface 11b on the front side has a left extending portion 11e that extends further from the left connecting portion 14a to the inside of the folding container 100. Similarly, a portion where the front side right side surface 11c and the back side right side surface 12b are connected so as to be bent forms a right connection portion 14b, and the right connection portion 14b is bent as an axis, and the right side surface 40 is bent inward. Can do. A part of the back side right side surface 12b has a right extending portion 12e extending from the right connecting portion 14b to the inside of the folding container. Furthermore, a male hook-and-loop fastener 60a and a female hook-and-loop fastener 60b are provided as fixing members for fixing the respective surfaces on the surface where the left extending portion 11e and the rear left side surface 12c are overlapped. . Similarly, a male hook-and-loop fastener 61a and a female hook-and-loop fastener 61b are provided as fixing members on the surface where the right extending portion 12e and the front side right side surface 11c are overlapped.

  The folding container 100 produced as described above is used as follows. A state in which the folding container 100 is used as a container (opened state) is shown in FIG. Next, as shown in FIG. 5, by bringing the front surface 10 and the back surface 20 close to each other, the left side surface 30 and the right side surface 40 are folded inward with the left connecting portion 14a and the right connecting portion 14b as axes. Then, by bringing the front surface 10 and the rear surface 20 closer to each other, as shown in FIG. 6, the left side surface 30, the right side surface 40, the front surface 10, and the rear surface 20 are finally substantially parallel to each other in a plate shape. Folded. At this time, the flexible bottom sheet 50 is notched under the left extending portion 11e and the right extending portion 12e, so that it can be folded inside the folding container as shown in FIG. If the lower part of the left extension part 11e and the right extension part 12e are cut out by a length equal to or longer than one half of the length of the left side surface or the right side surface, the bottom sheet 50 has the left extension part 11e and the right side. It can be folded without interfering with the extended portion 12e. On the other hand, in order to change from a folded state to a use state as a container, an operation opposite to that described above may be performed.

  According to the folding container 100 according to the first embodiment, the front-side left side surface 11b and the back-side right side surface 12b are slightly inward by the back-side left side surface 12c and the front-side right side surface 11c, respectively, when in a rectangular parallelepiped or cubic state. Since it is biased, if both the front surface 10 and the back surface 20 are brought close to each other, both side surfaces are naturally folded inward. Therefore, it is possible to fold only by bringing the front surface 10 and the back surface 20 close to each other. Therefore, it can fold rapidly compared with the conventional folding container. Moreover, since it can fold in the area | region of the substantially cube or substantially rectangular parallelepiped of the folding container 100 when folding, it will become possible to fold if the folding container 100 can be installed. Even in the case of expanding from the folded state to the container state, the left extending portion 11e and the right extending portion 12e are disposed inside the back side left side surface 12c and the front side right side surface 11c. The left extending portion 11e abuts on the back side left side surface 12c and the front side right side surface 11c, thereby functioning as a locking piece, and prevents the left side surface 30 and the right side surface 40 from bulging outward from the planar state. Therefore, it is possible to prevent the left side surface 30 and the right side surface 40 from expanding too much and narrowing the container region. Further, since the flexible bottom sheet 50 is provided on the bottom surface, the folding container 100 is surely expanded into a cubic or rectangular parallelepiped shape by the flexible bottom sheet 50. Therefore, it does not become a state like a parallelogram, and it can prevent that a container area | region becomes narrow.

(Second Embodiment)
FIG. 7 shows a perspective view showing an outline of the configuration of the folding container 100 according to the second embodiment. In the folding container 100 according to the second embodiment, a bottom plate 6 that is flexibly connected to the lower side 61 of the back surface 20 is disposed on the top surface side of the bottom sheet 50. The bottom plate 60 is made of corrugated plastic and has the same shape as the inner bottom surface of the folding container. A grip portion 62 is attached to a part of the bottom plate 60 so that the bottom plate 60 can be easily lifted. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  In the folding container 100 created in this way, if the bottom plate 60 is tilted in the expanded state, the bottom sheet 50 supports the bottom plate 60, so that the bottom plate 60 is positioned without using any other fixing means. A plate-like bottom surface can be formed.

(Third embodiment)
FIG. 8 is a perspective view schematically showing the configuration of the folding container 100 according to the third embodiment. The folding container 100 according to the third embodiment is formed such that the height ε of the folding container 100 is shorter than the width ζ of the left side surface 30 and the right side surface 40. Further, the bottom plate 60 is formed so as to be foldable in parallel with the lower side 61 of the back surface 20 at the center 63 of the bottom plate 60. In addition, when the folded bottom plate 60 is folded, the folded bottom plate 60 does not interfere with the back side left side surface 12c and the back side right side surface 12b, so that the folded bottom plate 60 has substantially the same thickness as the folded bottom plate 60. The folding line 12g is provided so that it can fold in the state which secured the area | region. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  The folding container 100 according to the third embodiment is folded in a state in which the bottom plate 60 protrudes from the upper end of the folding container 100 because the width of the bottom plate 60 is longer than the height of the folding container 100 when the folding container 100 is folded. Although there is a possibility, by folding the bottom plate 60 in the direction of arrow A shown in FIG. 9, the bottom plate 60 can be folded without protruding from the upper end. Further, since the left side surface 30 and the right side surface 40 can be folded along the fold line 12g, when the folding container 100 is folded, a storage area for the bottom plate 60 can be secured, and the left side surface 30 and the right side surface 40 are separated from each other. There is no interference.

(Fourth embodiment)
The top view which shows the outline of a structure of the folding container 100 concerning 4th Embodiment is shown by FIG. In the folding container 100 according to the fourth embodiment, the total width of the width α of the front side left side surface 11b and the width α ′ of the rear side right side surface 12b is the front side (the first central surface 11a or the second central surface 12a). Is shorter than the width β. Since other points are the same as those of the first embodiment, description thereof is omitted.

  According to the folding container 100 according to the fourth embodiment, as shown in FIGS. 10a to 10d, the left extending portion 11e and the right extending portion 12e do not interfere with each other during the folding process. Therefore, even when it is finally in a plate-like state, the front surface 10, the rear surface 20, the front side left side surface 11b, the front side right side surface 11c, the back side left side surface 12c, and the back side right side surface 12b are almost completely parallel. be able to. Therefore, it can be folded into a plate-like body thinner than the first embodiment.

(Fifth embodiment)
A perspective perspective view schematically showing the configuration of the folding container 100 according to the fifth embodiment is shown in FIG. As for the folding container 100 concerning 5th Embodiment, the left extension part 11e and the right extension part 12e are all in the one back side surface formation member 12 side. The lower side 61 of the back surface 20 is provided with a bottom plate 60 that is connected to bendable. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

  Since the bottom plate 60 is provided on the lower side 61 on the back surface 20 side having the left extending portion 11e and the right extending portion 12e, the bottom plate 60 is tilted to the right extending portion 11e and the right extending portion by tilting the bottom plate 60. The installation part 12e is pressed. Therefore, the left side surface 30 and the right side surface 40 are expanded by tilting the bottom plate 60. Therefore, the folding container 100 can be assembled simply by tilting the bottom plate 60. Furthermore, the back side left side surface 12c and the back side right side surface 12b are not parallel in a strict sense, and the left extending portion 11e and the right extending portion 12e are slightly biased and arranged inside the folding container 100. Therefore, the back side left side 12c and the back side right side 12b can be supported by tilting the bottom plate 60. That is, for example, as shown in FIG. 11, if the right side surface 40 is a plane, it exists at the position of the imaginary line η, but actually the back side right side surface 12 b exists inside the folding container 100 from the imaginary line η. Yes. Therefore, when the bottom plate 60 is tilted, the bottom plate 60 spreads the back side right side surface 12b outward as if it were forced. On the other hand, the front side right side surface 11c is pressed inward. By pressing each other in this manner, the back side right side surface 12b is fixed and can maintain a stable container state. Similarly, the back side left side surface 12c is also fixed.

(Sixth embodiment)
A perspective view schematically showing the configuration of the folding container 100 according to the sixth embodiment is shown in FIG. In the above-described embodiments, the explanation has been made by using the plate-like plastic cardboard, but the plastic cardboard is not necessarily required. For example, a mesh member may be used as shown in FIG.

  As shown in FIG. 13, the folding container 100 according to the sixth embodiment has a net-like member in which the flat portion of each of the first central surface 11 a, the front side left side surface 11 b and the front side right side surface 11 c of the front side surface forming member 11 is ( That is, it is formed in a net shape or mesh shape) or a sheet. A belt-like bag body 91 is provided around each surface by sewing. Similarly, the second center surface 12a, the back side left side surface 12c, and the back side right side surface 12b of the back side surface forming member 12 are similarly made of a mesh member or sheet. A belt-like bag body 91 is provided around each surface by sewing. A plastic plate-like rigid member 92 is inserted into the bag body 91. The rigid member 92 assists in maintaining a rectangular shape by imparting rigidity to the ridgeline of the self-standing folding container 100 or in the vicinity of the ridgeline. Note that the two adjacent plastic flat plate-like rigid members 92 are provided so that their end portions are not directly in contact with each other at a ridge angle with a gap therebetween. For this reason, it is also bendable at each ridge angle. When the flat plate-like rigid member 92 is used, it is difficult to bend it if it is arranged at the ridge angle, so it is arranged in the vicinity of each ridge angle. The left connecting part 14a and the right connecting part 14b are connected by sewing. Thus, by making all the surfaces of the front side surface forming member 11 and the back side surface forming member 12 with a net-like member or a sheet member, the folding container 100 that is lightweight and easy to fold can be provided.

(Seventh embodiment)
FIG. 13 shows a perspective view showing the outline of the configuration of the folding container 100 according to the seventh embodiment. The folding container 100 according to the seventh embodiment includes a lid body 80 that is connected to the upper side of the back surface 20 so as to be bent by a connecting portion 83. The lid 80 includes a flat surface 81 having the same size as the outer periphery of the folding container 100 and a lid fixing piece 82 formed around the periphery. Since other points are the same as those of the third embodiment, description thereof is omitted. Thereby, the folding container 100 can be used as a container having a lid.

  The present invention is not limited to the above-described embodiment, and can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  As shown in the above-described embodiment, the present invention can be industrially used as a self-supporting foldable container.
