Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corrugated cardboard container for recovering used paper, for example, which can transport ikebana or the like while being immersed in water.

[0002]

[Prior art and its problems]

 Conventionally, when carrying ikebana etc. while being immersed in water, a bucket made of plastic etc. is generally used.

However, when an ikebana or the like is transported in the plastic bucket, it is firstly expensive because it is made of plastic, and secondly, it is a three-dimensional object, so it is necessary to secure a wide storage space. Thirdly, there are many problems such as the need for cleaning and the like when reusing it because soil is likely to be attached and soiled, and the work is very complicated. .

The present invention was devised in view of the current situation, and its purpose is to make it easy to assemble and dismantle, and not to lose its shape even when water is stored in it. The present invention aims to provide a corrugated cardboard container that is suitable for storing and transporting the corrugated cardboard and is excellent in recoverability of used corrugated cardboard after use.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, a corrugated cardboard container capable of collecting waste paper is folded along the mountain fold line and the valley fold line formed on the corrugated cardboard, and the corrugated cardboard is folded into a substantially concave section. It is characterized in that it is formed by bending and the inner surface of the bent corrugated paperboard is waterproofed with a coating agent.

[0006]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

1 to 4 show a first embodiment of the present invention. A corrugated cardboard container for recovering waste paper according to this embodiment is a sheet whose one side is mainly composed of styrene-acrylic copolymer. By bending the corrugated paperboard 10 surface-treated with the agent along the set mountain fold lines (shown by broken lines in the figure) and valley fold lines (shown by dashed lines in the figure) The corrugated cardboard container having a substantially concave cross section as shown in FIG. 1 is formed.

As shown in FIG. 2, the corrugated paperboard 10 is adhesively fixed between the liner 10a coated with the coating agent, the liner 10b not coated with the coating agent, and the liners 10a and 10b. And a continuous wavy core 10c that has been formed, and is cut into the size shown in FIG.

Further, the coating agent applied to the liner 10a does not leak even if it contains water, so that the coating amount is set to 1 g / m ^{2 to} 30 g / m ^{2 so} as to ensure moisture resistance and waterproofness. First, it maintains the disintegration property when recovering waste paper.

As shown in FIG. 3, the corrugated paperboard board 10 having the above-described structure has a bottom plate portion 11 at the center thereof defined in a rectangular shape by four valley fold lines V1, V2, V3 and V4. In addition, the left and right side surface plate portions 12 and 13 which are continuously provided in the left and right direction of the bottom plate portion 11 are defined by three valley fold lines V4, V5, V6 and V2, V7, V8, respectively. The front plate portion 14 continuously provided in the upper direction of the bottom plate portion 11 is defined by two valley fold lines V3, V9 and two mountain fold lines M1, M3. The back plate portion 15 which is continuously provided in the downward direction of 11 is defined by two valley fold lines V1 and V10 and two mountain fold lines M2 and M4.

Further, overlapping portions 16 to 19 are formed at the four corners of the corrugated paperboard 10. Each of the overlapping portions 16 to 19 has one extension extending in a diagonal direction of the bottom plate portion 11. Valley fold lines V11 and V12 are formed respectively.

Therefore, first, the corrugated paperboard board 10 is bent along the valley fold lines V1 to V4 so that the left and right side surface plate portions 12, 13 and the front surface plate portion 14 and the back surface plate portion are inserted from the four sides of the bottom plate portion 11. After erected 15, the overlapping portions 16 to 19 are bent along the valley fold lines V9 to V12 to assemble a corrugated cardboard container having an open top and a concave cross section.

When the corrugated paperboard 10 is assembled according to the above procedure as shown in FIG. 1, the left and right side plate parts 12, 13, the front plate part 14, the rear plate part 15 and the overlapping parts 16 to 19 are overlapped. The assembled state is maintained by fixing the mating portion with a clip C as shown in FIG. Of course, instead of the clip C, an adhesive tape (not shown) may be used.

When the cardboard container is assembled with the clip C or the adhesive tape as described above, the liner 10a coated with the coating agent is located on the inner surface side of the cardboard container, and the corrugated board 10 is waterproof. Even if water is added up to the height position of each edge H of the front plate portion 14 and the back plate portion 15 which have not been treated, there is a risk that the water will soak from the above edge portions and weaken the corrugated paperboard 10. There is no

Further, when the cardboard container is disassembled, it can be easily disassembled only by peeling the clip C or the adhesive tape.

FIG. 5 and FIG. 6 show a corrugated board container according to a second embodiment of the present invention. The corrugated board container according to this embodiment has a height greater than that of the corrugated board container according to the first embodiment. The height of the left and right side plate portions 22, 23, front plate portion 24, rear plate portion 25, and the overlapping portions 26 to 29, which are continuously provided on the four sides of the bottom plate portion 21 of the corrugated paperboard 20, are made the same. Other than the formation, the structure is the same as that of the first embodiment, and therefore, the same reference numerals are attached to the drawings, and the detailed description thereof is omitted here.

The corrugated cardboard container configured as described above has a low height dimension, and since the limit height position where water is put is the upper end portion of the opening, it is easy to handle and the clip C can be easily attached and detached. As a result, the effect of facilitating assembly / disassembly work can be obtained.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it is extremely easy to assemble and disassemble a cardboard container, and there is no risk of losing its shape even when water is stored. -It is suitable for transportation, and because it does not use adhesives such as glue, it has a number of excellent effects such as good recovery of used corrugated cardboard after use.
