In addition, since the removal of the locking portion 31 from the inside of the insertion hole 20 is restricted, the pair of long side walls 13 stop rotating with respect to the bottom wall 12 in a state where the exposed portion 30 comes out of the inside of the insertion hole 20. Then, they are held in a tapered shape that becomes wider toward the upper part.

The container body 11 is formed by bending a single sheet material. As shown in FIG. 3, this sheet material 21 is made of a synthetic resin foam.
It is formed in a substantially cross shape in the unfolded state. A pair of first folds 22a and second folds 22b extending in the horizontal and vertical directions in FIG. 3 are formed at the center of the sheet material 21 so as to form a rectangular shape. The inner part surrounded by the first fold 22a and the second fold 22b becomes the center piece 22.

1 will be described. As shown in FIG. 4, in order to assemble the container body 11, first, the first bent piece 23 is attached to the center piece 22 of the sheet material 21 at the first fold 22 a.
The bottom wall 12 is formed by being bent upward by 0 °. Next, the third bent piece 25 is bent 90 ° in the lateral direction at the fourth fold 23b with respect to the first bent piece 23, and the third bent piece 25 is bent at the fifth fold 25a, so that the first bent piece 23 is exposed. Insert 19 having a portion 30 and a locking portion 31
Is formed.

Subsequently, the second fold 2
At 2b, the second bent piece 24 is bent upward so that its inner surface contacts the insertion piece 19. Thereafter, as indicated by the arrow in the figure, the sixth fold 24 is inserted such that the upper half of the second bent piece 24 sandwiches the insertion piece 19 between the upper half and the lower half thereof.
The hook 27 is folded downward at a, and the claw portion 27 is engaged in the engagement hole 28. When the claw portion 27 and the engagement hole 28 are engaged, the second bent piece 24 is held in a state of being folded in two,
The short side wall 14 having the insertion hole 20 inside is formed by the folded second folded piece 24.

Thereafter, the upper portion of the first bent piece 23 is bent 90 ° in the transverse direction at the third fold 23a, thereby forming the first bent piece 23.
The long side wall 13 is formed by the lower part of the bent piece 23, and the lid part 16 is formed by the upper part. Then, in the lid 16, the fourth bent piece 26 is bent downward by 90 ° at the fourth fold 23 b to form the sticking portion 17, and the surface fastener 18 of the sticking portion 17 is formed into a surface fastener of the outer surface of the short side wall 14. By joining to the container 18, the container body 11 as shown in FIG. 1 is formed.

Next, a method of using the container body 11 will be described. When the container is to be stored in the container body 11, first, as shown in FIG. 2, the bonding between the sticking portion 17 and the short side wall 14 is released, and the lid portion 16 is opened to the outside of the container body 11 to be opened. While the part 15 is opened, the lid part 16 is grasped by hand and pulled further out of the container body 11. Then, by pulling the lid 16, as shown by an arrow in FIG. 5A, the pair of long side walls 13 is rotated with respect to the bottom wall 12 so as to separate the upper portions from each other. The exposed part 30 starts to be pulled out from the insertion hole 20.

As shown in FIG. 5 (b), when the long side wall 13 is rotated to the position where the entire exposed portion 30 of the insertion piece 19 is withdrawn from the insertion hole 20, the upper surface of the locking portion 31 is inserted. 20
Inside, the short side wall 14 comes into contact with the inner surface of the folded portion 14a, whereby the entire insertion piece 19 is prevented from coming out of the insertion hole 20, and the rotation of the long side wall 13 stops. In this state, as shown in FIG. 1, the container body 11 has an opening 15 that is expanded, and a container is accommodated in the container body 11 from the expanded opening 15. When the opening 15 is widened, it is easy to store the contents in the container main body 11, and the stored goods in the container main body 11 can be viewed from obliquely above. The number and the like can be easily confirmed.

After the container is stored, the opening 15 of the container body 11 is closed. When closing the opening 15, first, the pair of long side walls 13 are rotated with respect to the bottom wall 12 so that the upper portions thereof approach each other from the state shown in FIG.
As shown in FIG. 2, the exposed portion 30 of the insertion piece 19 is inserted into the insertion hole 2.
0 is inserted. Next, the lid 1 on the upper part of both long side walls 13
6 is bent inwardly of the container body 11, and then the sticking portion 17 is bent downward to join the hook-and-loop fastener 18 to the hook-and-loop fastener 18 on the outer surface of the short side wall 14. Then, the opening 15 is closed by the pair of lids 16, and both the lids 16 are fixed while the opening 15 is closed by joining the sticking part 17 and the short side wall 14.
At this time, both lids 16 are fixed, so that
6, the long side wall 13 connected to the top is also the bottom wall 1
2 is restricted, and the long side wall 13 is maintained upright from the long side edge of the bottom wall 12. The short side wall 14 is provided with the insertion piece 19 of the long side wall 13 in the insertion hole 20.
Is inserted and the sticking portion 17 of the lid 16 is joined to the outer surface, so that the bottom wall 12 is maintained upright from the short side edge. The container body 11 in which the container is accommodated therein and the long side wall 13 and the short side wall 14 are in an upright state with respect to the bottom wall 12 applies a load applied from above to the long side wall 13 and the short side wall 14. Since the whole can be efficiently supported, a plurality of them are piled up and conveyed so as to save space.

It is also possible to stack a plurality of container bodies 11 in a state in which the contents are stored, to keep them cool in a cool box, to store them in a warehouse, and so on. In this case, since the long side wall 13 and the short side wall 14 are bent with respect to the bottom wall 12, no gap is formed between the bottom wall 12 and the long side wall 13 and the short side wall 14. In addition, the adjacent long side wall 13 and short side wall 14 have a height
Since the insertion pieces 19 having a length substantially equal to the height of the first side wall 1 are connected to each other by being inserted into the insertion holes 20, almost no gap is formed between the adjacent long side walls 13 and short side walls 14. In addition, since the lid 16 is bent from the upper end of the long side wall 13 and the adhesive portion 17 is joined so as to cover the short side wall 14 from the outside, the peripheral edge of the opening 15 closed by the lid 16 is formed. Almost no gap is formed. For this reason, the container main body 11 has a high hermeticity inside, so that foreign matters such as insects, dirt, dust, etc. enter the container main body 11 during storage, or when the storage body is taken out of the cool box, the cool air suddenly escapes. It is difficult to cause such problems.

When the contents are taken out at the destination, as shown in FIG. 1, the opening 15 of the container body 11 is opened and the pair of long side walls 13 Are rotated so as to separate the upper portions from each other, and the opening 15 is expanded. Thereafter, the emptied container body 11 is placed in a nesting state.

When the container body 11 is brought into the nesting state, first, the short side wall 14 is moved from the state shown in FIG.
2, the long side walls 1 are separated from each other so that
3 is rotated outward. Then, as shown in FIG. 6, the insertion piece 19 is bent at a fold formed at the boundary between the exposed portion 30 extracted from the insertion hole 20 and the locking portion 31 inserted in the insertion hole 20. The pair of opposing long side walls 13 and short side walls 14 are maintained so as to form a tapered shape that becomes wider toward the top. In this manner, the nesting state is a state in which each of the pair of opposing long side walls 13 and short side walls 14 has a tapered shape that becomes wider toward the top. The container main body 11 in the nesting state is stacked in a space-saving manner by inserting the lower part of the container main body 11 in the upper position into the container main body 11 in the lower position, and is returned to the carrier, Stored in a warehouse.

The effects exerted by the above embodiment will be described below. The container body 11 has adjacent long side walls 13 and short side walls 1
4 are formed integrally with the long side wall 13 and the short side wall 14, respectively.
The number of parts is small, and the configuration can be simplified. In addition, assembling work in the stacking state and the nesting state rotates the long side wall 13 and the short side wall 14,
This can be performed by inserting and removing the exposed portion 30 of the insertion piece 19 from the insertion hole 20, and such an assembling operation can be performed easily and quickly. The short side wall 14 is formed from the short side edge of the bottom wall 12. The second bent piece 24 of the sheet material 21 bent upward is folded at the center thereof. Therefore, when the short side wall 14 is molded, the insertion hole 20 is formed.
No work such as forming the short side wall 14 and the insertion hole 20 can be easily formed. In addition, the insertion hole 2
0 is in the shape of a bag whose upper part is closed,
When the insertion piece 19 moves in the insertion hole 20 with the rotation of the third side 3, the upper surface of the locking portion 31 comes into contact with the inner surface of the folded portion 14a of the short side wall 14, so that the amount of rotation of the long side wall 13 is reduced to a predetermined amount. It is possible to prevent the connection between the long side wall 13 and the short side wall 14 from being released.

The exposed portion 30 is formed in an isosceles triangular shape having two sides 30 a and 30 b having the same length as the height of the short side wall 14. The upper portion can be prevented from contacting the inner surface of the insertion hole 20. In addition, by setting the same two sides 30a and 30b to have the same length as the height of the short side wall 14, it is possible to prevent a gap from being formed between the adjacent long side wall 13 and the short side wall 14. The hermeticity of the main body 11 can be improved.

The other side 30 b of the exposed portion 30 and the locking portion 3
When the opening 15 is widened, the upper surface of the locking portion 31 is securely brought into contact with the inner surface of the folded portion 14a of the short side wall 14 in the insertion hole 20 when the angle θ between the upper sides of the first side 1 is 90 °. Can be done.

The container body 11 is made of one sheet material 21
Is bent, so that the number of parts is one, and the configuration can be simplified. In addition, since the insertion piece 19 is also formed by bending a part of the sheet material 21, the long side wall 1 is formed.
The configuration of the insertion piece 19 that regulates the amount of rotation of the third to a predetermined amount can also be simplified.

The insertion piece 19 is connected to the exposed portion 30 and the locking portion 3.
By forming a fold at the boundary with the first fold 1 and making it foldable at this fold, the rotation of the short side wall 14 with respect to the bottom wall 12 becomes easy, and the container main body 11 can be easily brought into the nesting state. .
