2. Description of the Related Art As is well known, numerous types of paper containers are known. However, when manufacturing a large container, since the material is paper, there are various structural problems. In other words, if it is a paper container for packing large home appliances, since it is placed on a trolley during transportation, the purpose is merely to protect the products stored inside from impact, so make a strong and water resistant container. No need. Further, since the outer surface is only required to display the contents, it is not necessary to specially decorate or treat the outer surface. However, when storing a heavy body such as a casket, sufficient strength is required because it is carried by several people, and it is water resistant because it stores dry ice inside. In addition, the outer surface must be properly decorated.

[0003]

Therefore, conventionally, most containers that require high strength, such as a casket, and are required to have water resistance and weather resistance, are made of wood or synthetic resin, and are therefore inexpensive and easy to use. It has been difficult to produce a container having a structure that is easy to handle and does not cause pollution by burning. Therefore, there is a demand for a paper container that is inexpensive and easy to handle, even if the container is required to have high strength, water resistance, and weather resistance.

The surface sheet material 45 has the entire side surface 4
Although it is adhered to the outer surface of the sheet, the left and right side edges are provided with fixing margins 46 extending from the side edges of the side surface portion 4, and the upper edge of the surface sheet material 45 is folded back to the inside of the side surface portion 4. The piece 47 is folded at the lower edge of the bottom surface 2 of the bottom surface 2, and a lower folded piece 48 that is adhered is extended. Then, an adhesive layer may be formed on the inner surfaces of the both fixing margins 46 in the same manner as the covering piece 36, and release paper may be attached.

The bottom surface portion 2, the left and right side surface portions 3 and the front and rear side surface portions 4 are formed by cutting one paper plate material a or forming a V-shape when the material paper plate material a is a honeycomb corrugated board. It is cut and integrally molded as a whole, and the bottom surface portion 2, the side surface portion 3 and the side surface portion 4 are configured to be bendably connected by the outer surface liner b. In this case, the surface sheet material 35 is attached to the side surface portion 3
After being adhered to the outer surface of the above, the lower folded piece 40 is folded and adhered to the lower surface of the bottom surface portion 2, and the upper folded piece 39 is folded and adhered from the upper edge of the side surface portion 3 to the inner surface. When the surface sheet material 45 is adhered to the outer surface of the side surface portion 4, the lower folded piece 48 is adhered to the lower surface of the bottom surface portion 2 and the upper folded piece 47 is folded and adhered from the upper edge of the side surface portion 4 to the inner surface. .

However, the bottom surface portion 2, the side surface portion 3 and the side surface portion 4
In the case of separately molding with, for example, honeycomb corrugated cardboard, when the surface sheet material 35 is adhered to the outer surface of the side surface portion 3, the lower folding piece 40 is adhered to the lower surface of the bottom surface portion 2, and the surface sheet material 45 is attached. After adhering to the outer surface of the side surface portion 4, the lower folding piece 48 is adhered to the lower surface of the bottom surface portion 2 so that the bottom surface portion 2, the side surface portion 3 and the side surface portion 4 are joined together.
5 and the surface sheet material 45 may be connected so as to be bendable. Further, for example, when the bottom face portion 2 and the left and right side face portions 3 are integrally formed from one piece of honeycomb corrugated board and the two side face portions 4 are individually formed, the bottom face portion 2 and the side face portion 3 are made of paper. The outer surface liner b of the plate material a may be connected, and the bottom surface portion 2 and the side surface portion 4 may be connected by the lower folded piece 48 of the surface sheet material 45.

In any of the above cases, each side surface portion 3
The non-water-permeable sheet 33 is attached to the inner surface of the sheet and the surface sheet material 35 is attached to the outer surface thereof, and the non-water-permeable sheet 43 is attached to the inner surface of the side surface portion 4 and the surface sheet material 45 is attached to the outer surface thereof. The side surface portion 3 is connected to the two opposite sides of the bottom surface portion 2, and the side surface portion 4 is bendably connected to the other two opposite sides.

Therefore, when the side surface portion 3 and the side surface portion 4 are assembled upright on the four sides of the bottom surface portion 2, the side edge portion 2 is formed.
1, the side edge portion 32, and the side edge portion 42 are obliquely cut at 45 degrees to form a container with an open upper surface in which the side surface portion 3 and the side surface portion 4 stand upright with respect to the bottom surface portion 2, but the corner portion of the container is formed. However, the joint portion of the side edge between the adjacent side surface portion 3 and side surface portion 4 is not attached.

Therefore, the side edge portion 32 and the side edge portion 42, which are formed by obliquely cutting the adjacent side surface portion 3 and side surface portion 4 at an angle of 45 degrees, are formed.
In the state where they are butted against each other, the covering piece 36 of the surface sheet material 35 is rolled up, the release paper of the fixing margin 46 is peeled off to bond the adhesive layer to the outer surface of the side edge of the side surface portion 3, and then the covering piece 36 is peeled off. The paper is peeled off and attached to the outer surface of the fixed margin 46. Therefore, the corner portion where the side edges of the side surface portion 3 and the side surface portion 4 are butted against each other is as shown in FIG.
As shown by, the fixing margin 46 is attached to the outer surface side edge of the side surface portion 3, and the covering piece 36 is attached to the outer surface of the fixing margin 46, so that the assembly is performed firmly. Further, since the side edge of the covering piece 36 coincides with the vertical ridgeline of the corner portion, the corner portion can be processed well.

Then, the release paper of the lower folding piece 38 is peeled off and attached to the lower surface of the bottom face portion 2, and the release paper of the upper folding piece 37 is peeled off and attached from the upper edge of the side face portion 3 to the inner surface. As a result, the corner portion is favorably processed with higher strength. In particular, a part of the side edge of the upper folding piece 37 is obliquely cut by 45 degrees in the same manner as the side edge portion 32 of the side surface section 3, so that the upper edge 31 of the side surface section 3 forms a 45 degree oblique line. Therefore, the appearance is good even when observed from above.

By assembling the four corner portions where the side edges of the side surface portion 3 and the side surface portion 4 are butted against each other as described above, each corner portion is firmly fixed and is attached to the four sides of the bottom surface portion 2. It is possible to configure a container having an open upper surface in which the side surface portion 3 and the side surface portion 4 are upright. Then, the non-water-permeable sheets 22, 33, 43 are attached to the upper surface of the bottom surface portion 2 and the inner surfaces of the respective side surface portions 3, 4, and the non-water-permeable sheet 22 stands upright with the tip portions 23 of the four sides low. Since it has a shallow dish-like shape, even if the body is stored and used as a casket and dry ice or the like for preventing decay is put therein, water does not seep out to the outside by the non-water-permeable sheets.

The paper container 1 of the present invention may basically be the frame body having the above-mentioned open upper surface, but when it is used as a casket, the lid portion 5 is also necessary.

If the bottom surface portion 2, the side surface portion 3 and the side surface portion 4 of the lid portion 5 are formed of honeycomb corrugated board,
Similarly, it is formed from honeycomb corrugated board. It is desirable that the lid 5 is a thick plate, and the decorative surface sheet material 51 is adhered to the upper surface similarly to the surface sheet material 35, and the non-water-permeable sheet material is adhered to the lower surface. Then, a quadrangular window hole 52 for viewing is provided near one end of the lid 5, and a window frame 53 having a T-shaped cross section is provided on the inner periphery of the window hole 52.
Rotatable lid pieces 54, 54 are provided on the upper surface of the opening of the window frame 53.

The lid piece 54 is in the shape of a double-door door with the window hole 52 divided in the vertical direction. Therefore, when the window hole 52 is opened, the left and right lid pieces 54 may be rotated upward, and when the window hole 52 is closed, the lid piece 54 may be rotated so as to close the upper surface of the window frame 53. Then, when L-shaped locking portions 55 that engage with the inner surfaces of the four corners of the paper container 1 are provided at the four corners of the lower surface of the lid 5, the paper container 1 is covered with the lid 5. It is possible to prevent the lid portion 5 from slipping down due to vibration, impact or the like in the worn state.

The present invention has been described above based on the embodiments shown in the drawings. However, the present invention is not limited to the above-mentioned embodiments, and can be carried out in any manner as long as the configuration of the claims is not changed. can do. For example, the fixing allowance and the covering piece may be provided on either the front, rear, left, or right side surfaces, or the paper board material may be made of any material.
