The second side surface portion 3 has a lower second side surface portion 3a below the middle inner folding line 5 and an upper second side surface portion 3b above the middle inner folding line 5, and further has a connecting portion. Four
Is a lower connecting portion 4a and an upper connecting portion 4 by an intermediate folding line 5.
It is divided into b and b, respectively.

Further, on both sides of the second side surface portion 3, a second
An oblique inward folding line 6 extending from the outer edge of the side surface portion 3 to the corner of the bottom surface portion 1 is formed.

Further, a valley fold line 7 is formed on the upper connecting portion 4b along a diagonal line directed inward, and the same is applied to the end portion of the upper first side surface portion 2b to which the connecting portion 4 is directly attached. A valley line 7 is formed.

Now, in the above-mentioned structure, in order to change the developed state of FIG. 3 to the flat assembled state shown in FIG. 4, each connecting portion 4 is attached to the inside of the end portion of the first side surface portion 2 with an adhesive or the like. After assembling together to form a quadrilateral frame having an open upper surface, only the first side portions 2 facing each other are bent so as to overlap with the bottom portion 1, and the diagonal inner folding line of the second side portion 3 is formed. Bend 6 In this state, the structure is flat as a whole, and if the connecting portion 4 is brought into contact with the inner surface of the end portion of the first side surface portion 2, they can be mechanically joined together, and since they are flat, they are not bulky to transport or store. However, the inner fold lines 6 are valley-folded from the unfolded state of FIG. 3 so that the triangular portion at the end of the second side surface portion and the connecting portion 4 are superposed on the surface of the bottom surface portion 1, and then the first side surface portion. 2 is folded so as to overlap with the surface of the bottom surface portion 1, the first side surface portion 2
Since the end portion of the above and the triangular portion and the connecting portion 4 are vertically overlapped with each other, the connecting portion 4 and the end portion of the first side surface portion 2 can be mechanically joined together.

In order to assemble the paper container stored in the above-mentioned folded state for use, if the first left and right side portions 2 are raised upright, the second side portion 3 is also raised at the same time. The assembled state is as shown in FIG.

Therefore, when the amount of the stored items is bulky and large, as shown in FIG. 2, only the heights of the first side surface portion 2 and the second side surface portion 3 can be stored, and the inner lid can be stored. Figure 8 with 8 attached

When the amount of the stored items is not so large and bulky, as shown in FIG. 1, the intermediate inner folding line 5 between the first side surface portion 2 and the second side surface portion 3 is folded to form the upper first portion. Side part 2a
When the upper fold line 7 and the upper second side face portion 3a are bent inward at a right angle and the valley fold line 7 is fold folded, each side face becomes the height of the lower side face portion to reduce the storage volume, and the inner lid 8 is covered to seal. By doing so, the stored items can be stored without rocking. Therefore, according to the present invention, the height of the paper container can be changed to two types, and the height can be freely used according to the stored items.

The present invention has been described above based on the embodiments of the drawings, but the present invention is not limited to the above-mentioned embodiments, and may be modified as long as the configuration described in the scope of claims for utility model is not changed. It can be carried out at any time.

[0018]

In summary, according to the present invention, both ends of the second side surface portion are connected to the connecting portions respectively joined to the end portions of the first side surface portion, and each first side surface is formed. The intermediate side folding line along the lengthwise direction is formed over the entire length in the middle part of the height of the portion, the second side surface portion, and the connecting portion, and the first side surface portion is the upper first side surface portion and the lower first side surface portion. A side surface portion, a second side surface portion are divided into an upper second side surface portion and a lower second side surface portion, and a connecting portion is divided into an upper connecting portion and a lower connecting portion, and a diagonal valley fold line is formed in the upper connecting portion. While forming, a valley fold line corresponding to the valley fold line of the upper connecting portion is also formed at the end of the upper first side surface portion, and the outer edge of the second side surface portion is formed on both sides of the second side surface portion. To a corner of the bottom surface portion, an oblique inward folding line is formed, and the first side surface portion and the second side surface portion are erected with respect to the bottom surface portion so that each connecting portion is connected to the first side surface. Made by bonding the end. Therefore, in the assembled state, not only can each of the oblique inward folding lines be folded to be thin and flatly folded, but also in the flattened state, the opposing first side surface portion is raised to the extent that it stands upright with respect to the bottom surface portion. It can be assembled into a box frame shape whose upper surface is open by itself, and in particular, each valley fold line can be easily changed between a flat state and an assembled state, and the first side surface portion and the connecting portion can be easily combined. Since it is polymerized and the valley fold line is also polymerized, the bending strength is high. Since the middle inward folding line is formed over the entire length of the first side surface portion, the second side surface portion and the connecting portion, the upper first side surface portion, the upper second side surface portion and the upper connecting portion are easy to fold, When packing a thin storage item, the fold line becomes clear due to the intermediate inward fold line and the appearance is good. In addition, since it can be easily attached to the machine during the molding process and can be folded flat without being bulky, it can be easily transported and stored in large quantities. Since there are two types of packaging means depending on the quantity, there is no need to prepare multiple types of containers according to the storage amount, and packaging materials can be kept to a minimum, such as high practical value. Can be provided.
