[0004] [Patent Document 1] Japanese Patent Application Publication No. 09-131569 [Patent Document 2] Republished WO2018 / 003019 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, a packaging box with plastic partitions is considered as a means for packaging a large number of small items such as parts, but in recent years, in light of the worsening global plastic waste problem, it is necessary to consider replacing plastic with other materials as much as possible in order to improve the global environment. Here, for example, if a large number of small items are packaged using packaging tools such as those described in Patent Documents 1 and 2 instead of plastic cardboard, it is necessary to make many small holes and recesses in the cardboard, and it is considered that it will be costly and laborious to dispose of the small pieces of paper generated by the hole punching process. Therefore, there is still room for improvement in the cardboard structure for packaging a large number of small items.

[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a cardboard partition that can easily package a large number of small items. [Means for solving the problem]

[0007] The partition according to the present invention is a cardboard partition comprising a base portion and a partition portion stacked on the base portion, capable of storing items in a space partitioned by the partition portion, wherein the base portion has a flat plate and a plurality of protrusion portions arranged on the flat plate along an edge of the flat plate, and the partition portion is made up of a plurality of partition pieces created by dividing a single cardboard sheet by forming uneven cut lines in the single cardboard sheet from one edge to the other edge opposite the one edge, and at least one of the plurality of partition pieces is configured so that its end portion is positioned and fixed between adjacent protrusion portions of the base portion, and the partitioned space is formed by the positional fixation resulting in adjacent partition pieces being spaced a certain distance apart across the protrusion portions. Effect of the Invention

[0008] According to the present invention, by simply forming uneven cut lines from one edge of a single cardboard sheet to the other and spacing the divided partition pieces a certain distance apart, it becomes possible to form a large number of partitioned spaces, making it possible to easily package a large number of small items.

[0012] 4, the package according to this embodiment is configured by disposing a partition D at the bottom of a plastic box 3 and storing small objects N (in this embodiment, 50 small nails) in the partition D. However, in the present invention, the object N may be any object as long as the effect of the present invention is exhibited, and examples of such objects include parts such as small screws, bolts, and nuts.

[0013] As shown in Figures 1 to 5, the partition D in this embodiment is made of cardboard and comprises a base portion 1 and a partition portion 2 stacked on the base portion 1, and is capable of storing an item N in the space S partitioned by the partition portion 2. The base portion 1 has a flat plate 11 and a plurality of protrusion portions 13 arranged on the flat plate 11 along the edge L1 of the flat plate 11. The partition portion 2 is composed of a plurality of partition pieces 21a, 21b generated by dividing a single cardboard sheet by forming an uneven cut line CL in the single cardboard sheet from one edge to the other edge opposite the one edge. At least one of the plurality of partition pieces 21a, 21b (represented by the symbol 21b in this embodiment) is configured so that its end portion is positioned and fixed between adjacent protrusion portions 13 of the base portion 1. The partitioned space S is formed by the adjacent partition pieces 21a, 21b being spaced a certain distance apart across the protrusion portion 13 due to this positional fixation.

[0014] 2 and 3, in the base 1 according to this embodiment, five protrusions 13 arranged on the flat plate 11 along the edge L1 of the flat plate 11 extend from the flat plate 12 so as to be bridged by the flat plate 12. With this configuration, the five protrusions 13 are reinforced by the flat plate 12. In the present invention, the flat plate 11 can be fixed by adhesive to the flat plate 12. Note that the present invention may be configured without the flat plate 12 as long as the effects of the present invention are achieved.

[0015] The blank 1B of the base 1 in this embodiment is formed from a single-flute cardboard sheet (double-sided cardboard sheet), and as shown in Figure 5, a pair of battens 12 are connected to a pair of opposing fold lines L1 of the flat plate 11, and the base 1 is in the state shown in Figure 2 by folding back the pair of battens 12 and the protrusions 13 extending therefrom at the pair of fold lines L1 of the flat plate 11 towards the flat plate 11 and adhesively fixing them to the flat plate 11 as necessary.

[0016] The concave and convex cut lines CL formed in the partition section 2 according to this embodiment are rectangular wave-shaped cut lines CL with an amplitude of A and a reference line passing through the origin as X, as shown in FIG. 6. Five rectangular wave-shaped cut lines CL are formed in the partition section 2 in parallel to each other, and the partition pieces 21a at the left and right ends and the three inner partition pieces 21b can be separated. The blank 2B of the partition section 2 according to this embodiment is formed from one double-flute corrugated cardboard sheet (double-sided corrugated cardboard sheet). In this embodiment, the partition pieces 21a at the left and right ends and the three inner partition pieces 21b are spaced apart by a certain distance without being completely separated from each other, so that the thickness of the cardboard acts as a partition wall to surround the small item N, and the small item N can be stored in the partitioned space S. In this embodiment, the partitioned space S is rectangular, but in the present invention, various shapes such as a rhombus can be adopted depending on the shape of the items to be stored. In addition, in the present invention, the shape of the cut line CL formed in the partition portion 2 can be any uneven shape other than a rectangular wave shape, so long as a partitioned space S is formed by separating adjacent partition pieces by a certain distance.

[0017] In the partition D of this embodiment, as shown in Figures 1 and 4, the four inner partition pieces 21b are fixed in position by adjacent protrusions 13, as described above, and the pair of left and right end partition pieces 21a are fixed in position by being sandwiched between the protrusions 13 and the inner wall of the box 3.

[0018] 1 to 3, in the partition D according to this embodiment, the width g of the partitioned space is equal to the width d of the protrusion 13, that is, the distance between adjacent partition pieces 21b (or partition pieces 21a and 21b) separated by the protrusion 13. The width g of the partitioned space can be designed depending on the dimensions of the articles to be stored, but in order to achieve the effects of the present invention, it is preferably 3 mm to 50 mm, and more preferably 5 mm to 30 mm.

[0019] As shown in Fig. 4, the partition D according to this embodiment is configured to be able to be stored in a plastic box 3. The box 3 has a rectangular shape when viewed from above and a flattened rectangular parallelepiped shape with a low overall height, and is composed of a lid part having a protruding part P and a body part having a recessed part R that can engage with the protruding part P, and the body part is configured to be able to store the partition D. The material of the box 3 is plastic, but this is not limited to the present invention, and various materials such as cardboard or thick paper may be used. The shape of the box 3 is also not limited to the present invention, and various shapes may be used as long as the partition D can be stored therein and the effects of the present invention are achieved.

[0020] The flat plate 11 of the base 1 according to this embodiment has an octagonal shape with the corners rounded off from a rectangle when viewed from above, as shown in Fig. 2. Similarly, the partition 2 and partition D according to this embodiment also have an octagonal shape to match the shape of the flat plate 11, as shown in Figs. 3 and 1. This shape makes it easy to remove the partition D from the box 3. Note that, in the present invention, the shapes of the flat plate 11, partition 2, and partition D when viewed from above may be a rectangle with no rounded off corners, or may be another polygon.

[0021] According to this embodiment, it is possible to form a large number of partitioned spaces S simply by forming an uneven cut line CL from one edge to the other edge of a single cardboard sheet and separating the divided partition pieces 21a, 21b at a certain distance from each other, making it possible to package a large number of small items N cheaply and easily.

[0022] <Other> The present invention is not limited to the above-described embodiment or the modified examples described throughout the specification, and appropriate changes and modifications can be made without departing from the technical concept of the present invention.

[0023] For example, the base 1 of the partition D according to the above embodiment is formed from a single-flute cardboard sheet, and the partition 2 is formed from a double-flute cardboard sheet, but the present invention is not limited to this, and any flute structure may be used as long as the effects of the present invention are achieved. Similarly, the thicknesses of the base 1 and the partition 2 may be any thickness as long as the effects of the present invention are achieved.

[0024] In addition, in the partition D according to the above embodiment, the base portion 1 and the partition portion 2 are fixed together by the protrusion portion 13, but the base portion 1 and the partition portion 2 may be fixed together by adhesive. [Explanation of symbols]
