Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a reinforced cardboard box, and more particularly to a reinforced cardboard box that can be folded in a compact size and is convenient for collection and transportation as a container.

[0002]

[Prior art]

 A corrugated corrugated core material with a liner paper bonded to at least one surface inside and outside is commonly used daily as a box container material. It is cut into pieces and assembled to form a box container.

On the other hand, since the strength of conventional corrugated paper tends to decrease due to moisture absorption, it is reinforced by sticking and laminating a stretch-strength synthetic resin film on the outer surface of the liner paper to enhance the compression resistance when forming a box. It is also proposed. (See Japanese Utility Model Publication No. 1-18349)

[0004]

[Problems to be solved by the device]

 However, in the past, the box containers for specific articles that were cut and assembled were only made as necessary to accommodate the specific articles, and were rarely collected, and they are now in a disposable state.

On the other hand, the corrugated cardboard box, which is used as a corridor, is usually foldable so that the top and bottom surfaces can be assembled together or fixed with adhesive tape for assembly and use. However, even if the product is collected after use and unassembled in an attempt to carry it out and unfold it, the unfolded folded state is bulky, requires a carrying space, and is inconvenient to handle.

[0006] A cardboard box, which uses a stretch-strengthened synthetic resin film on the outer surface of the liner paper as a general guide to enhance the compression resistance, is a model that is cut at the time of assembly, even if it has good waterproofness and compression resistance. The cut surface when formed is partly exposed as it is, and it has not yet been completely prevented that moisture can enter from the part.

In view of the above-mentioned situations, the present invention has an object to solve these conventional problems, and in particular, in cutting formation, by finding a new cutting development shape, the bulk at the time of collection and transportation is improved. Its purpose is to make it small and compact for easy handling, to obtain a folded polymerized portion to enhance the strengthening, and to eliminate the exposed cut surface to improve water resistance.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the corrugated cardboard box of the present invention is constructed as follows. That is, using a corrugated cardboard with a liner material bonded to at least the outer surface side of a core material, the bottom surface of a rectangular box, four side surfaces continuous to the four side edges of the bottom surface via fold lines, and an upper part Folding tongues that continue to the outer side of the side face via double folding lines, folding tongues that continue to the outer sides of the left and right side faces via folding lines, and upper and lower sides and left and right side faces that are orthogonal to each other. A box-based component piece consisting of a stacking piece with a fold-fold line extending between the side edges is formed in series, and further fold lines are formed with a small gap outside the fold line on both the upper and lower sides. On the other hand, a lid surface that covers the upper surface of the box, side abutments that are continuous on both the left and right sides of the lid surface via double fold lines, and a tongue piece that is continuous on the top and bottom of the lid surface via fold lines, respectively. On the outside of the upper tongue piece, a lid component piece consisting of a mounting piece continuous via a double fold line is also formed in series from the corrugated cardboard paper. Next, the box main body component piece and the lid component piece are bent by folding lines, and the attachment piece is fixed to the outer surface side of the lower side surface of the box main body component piece and assembled to each other to form a box.

It should be noted that, in the above-mentioned configuration, the box-main component piece and the lid component piece are formed separately, but the invention described in claim 2 eliminates the attachment piece of the lid component piece and replaces the upper tongue of the lid component piece. The pieces are directly and integrally formed on the outer side of the lower side surface of the box-shaped component piece through a fold line.

Further, in each of the above constitutions, the liner material is a corrugated cardboard paper in which a general liner paper is adhered to the inside and outside of the core to at least the outer surface side. Especially, at least to the outer surface side of the liner paper, the stretch reinforced synthetic resin film is used. Corrugated cardboard laminated with is excellent in water resistance and compression resistance.

[0011]

[Action]

 The corrugated cardboard box according to the present invention is assembled as a corrugated cardboard box having a bottom surface, four side surfaces and a lid surface by bending the respective folding lines. At that time, the cut surface during cutting is covered and cannot be seen from the surface, and there is no room for moisture to enter. Therefore, when the stretch-strengthened synthetic resin film is laminated on the outer surface of the liner material of the corrugated paper, there is no room for water to permeate along with the compressive force, and complete water resistance is achieved.

In addition, at the time of collection and folding, it is possible to fold it into a compact state without difficulty as shown in FIG. 4 due to the presence of double folding lines. It becomes possible to accommodate a plurality of them in parallel. In addition, by folding the overlapping piece with a fold-fold line, it can be made in the overlapping part, increasing the strength.

[0013]

[Embodiment of device]

 Hereinafter, embodiments and examples of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a developed shape of a box main constituent piece of a corrugated cardboard box of the present invention, and FIG. 2 is a developed shape of a lid constituent piece. In FIG. 1, 1 is a rectangular bottom surface 2a to 2d which is a bottom surface portion when the box is formed. Is a side surface continuously formed on each of the four sides of the outer circumference of the bottom surface 1 through fold lines (a), (b), (c), and (d) (hereinafter, in order to make it easy to understand, it will be referred to as top, bottom, left, and right). Basically, the bottom surface 1 and the side surfaces 2a to 2d form a main part of the box, but various types are required for assembly. That is, among the above four side surfaces 2a to 2d, the upper side surface 2a is further provided with the folded back tongue piece 3 continuously on the outer side (upper side in the figure) through the double folding line (e). In addition, folding tongue pieces 4 and 5 are formed on the outer side surfaces of the left and right side surfaces 2b and 2d through folding lines (f) and (g), respectively. In addition, side surfaces 2a and 2b, 2b and 2c, 2c and 2d, 2d and 2a, which are adjacent to each other on the upper, lower, left and right side surfaces 2a to 2d, are orthogonal to each other and serve as folding line side (wo), (wa), (f) (yo). ), (Ta) (re), (so) and (tsu) and have a fold-fold line (h) (ri), (nu) (ru) diagonally in the middle so that it can be folded. Pieces 6a to 6d are formed. Further, on the outer side of the fold lines (a) and (c) of the upper and lower side faces 2a and 2c of the above-mentioned component piece, another fold line (ne) and (na) are formed with a small gap a across the overlapped piece. Has been done.

The bottom surface 1, the side surfaces 2a to 2d, the folded back tongues 3, the folded tongues 4 and 5, and the overlapped tongues 6a to 6d are arranged in a line from a piece of corrugated cardboard through a fold line or the like. It is cut and formed into a box-based component as a whole. On the other hand, the lid component piece shown in FIG. 2 is continuous through a lid surface 7 located at the center and a double fold line (ヰ) provided on both left and right sides of the lid surface 7 with a small gap. And side tongues 8a and 8b formed as described above, tongues 9a and 9b that are continuously formed on the upper and lower sides of the lid surface 7 with folding lines (ra) and (c), and above the upper tongue 9a. It also has a mounting piece 10 formed continuously through double fold lines (No), and is also cut and formed from one sheet of corrugated paper.

In this way, the box main component piece and the lid component piece, which are each cut into a series of pieces, are fixed to the outer surface of the side surface 2c by glue or the like, and the lid component piece is bent through the fold lines to be polymerized. The pieces 6a to 6d are superposed on the inner surface of the side face by folds, and the upper surface of the box main body is covered with a lid, and the tongue piece 9b is folded back to the folded portion of the tongue piece 3 to be fitted therein. For example, a cardboard box as shown in FIG. 3 is formed. In this case, if the tongue pieces 9a of the lid component pieces are arranged in a continuous series instead of the attachment pieces 10 of the lid component piece, the box main component piece and the lid component piece are formed in series from one corrugated cardboard without dividing. can do. Such a cutting configuration is advantageous in a relatively small cardboard box.

The corrugated paperboard constituting the corrugated cardboard box may be one in which a liner paper is bonded to the inside and outside of a general core material at least on the outer surface side. However, as the liner material, at least the outer surface of the liner paper is used. By using corrugated cardboard with a liner material laminated with stretch-strengthened synthetic resin film on at least the outer surface inside and outside of the core material, the stretch-strengthened synthetic resin film is laminated to obtain water resistance and compression resistance. It is advantageous. As the synthetic resin material to be laminated, polyester resin (PET), polypropylene resin, etc. are usually used.

In particular, when assembling the box main component shown in FIGS. 1 and 2 and the lid component as shown in FIG. 3, there is no cut surface in the bent portion from the bottom surface 1 to each side 2a to 2d, and each side On the upper side of the side, one of the side surfaces 2c is covered with the attachment piece 10 of the lid component piece, and the other side surfaces 2a, 2b and 2d have the folded back tongue piece 3 and the folded tongue pieces 4 and 5, respectively. Not exposed.

Therefore, unlike the conventional case, the cut surface is not exposed to any one, and it can be formed in a corrugated cardboard box without exposing the cut surface at all. Therefore, there is no concern about moisture permeation from the exposed cut surface, which has been a concern in the past.In particular, when using corrugated cardboard that has a water-repellent synthetic resin film laminated on the outer surface to improve water resistance, it is even more water resistant. Is improved.

In the formation of the corrugated cardboard box, when the polymerization contact pieces 6a to 6d are polymerized and attached to the inner surface of the side piece, they may be fixed by a stopper to prevent the spread.

Further, the polymerization piece starts polymerization, and the folded pieces and the folded pieces overlap each side surface 2a to 2d (the folded pieces and the folded pieces may be folded as they are, or may be further fixed by being folded). The strength is extremely high.

In addition, according to the present invention, it is possible to increase the capacity by increasing the internal capacity of the box by overlapping them to increase the rising.

The above is the case of assembling and making a corrugated cardboard box. However, when the corrugated box is used after passing through and is collected, it can be folded as shown in FIG. 4 and becomes a compact. The size of the corrugated cardboard box that can be unassembled can be stored in parallel, making it extremely convenient for collection, and in combination with the strength of the entire box, the repeated use of the box is doubled compared to the past. The cost can be reduced, and the economical efficiency can be significantly improved.

[Effect of device]

 As described above, the present invention is a corrugated ball box in which the folded tongue piece, the folded tongue piece, and the overlapping piece with the fold-fold line are provided on the side surface of the box, and the lid constituent piece is assembled to the box main constituent piece. At this time, the cut edge of the corrugated cardboard is not visible at all from the outside, so it has good waterproof and dustproof effects from the outside, and at the time of recovery, by folding the polymerization piece into a pleated shape and polymerizing it. Combined with the double fold line with a small gap, it can be folded easily and compactly, and multiple cardboard boxes can be stored in parallel and transported, which is extremely effective for cost reduction. Yes, it has a remarkable effect to make handling of the multi-tiered ball box easy. Moreover, the corrugated box of the present invention has a double or triple overlapping portion formed by the above-mentioned overlapping pieces to increase its strength and the number of times it can be used as a passage can be doubled as compared with the conventional case.

Further, by using a liner material in which a stretch-reinforced synthetic resin film is laminated on at least the outer surface of a liner paper as a material for forming the corrugated cardboard box of the present invention, not only the water resistance but also the compression resistance is enhanced and the practicality of the cardboard box is improved. It is expected to have a remarkable effect of significantly improving the

Further, the present invention is different from the conventional corrugated cardboard box formation in that it has an advantage that the inside of the corrugated box can be increased in size by increasing the capacity inside the box, so that it can be used as a general corrugated cardboard box. Of course, it has a great economic effect when it is used as a communication.
