TECHNICAL FIELD The present invention relates to a packaging material for holding articles, which is used when storing articles in a packing box, and a method for assembling the packing material.

2. Description of the Related Art As a packing material for holding articles of this type, there is known a packing material in which a sheet member such as corrugated cardboard is folded to form a holding portion for holding the article. For example, as shown in FIG. 9, one cut sheet member 100 is folded a plurality of times to form side walls 101 having a plurality of sides, and then folded inward near the lower corners 102 of the adjacent side walls 101. , which is referred to as an article holding structure 103 (hereinafter referred to as a holding structure). However, in order to form such a holding structure 103, each side must be bent six times. Moreover, since the bending direction of the holding structure 103 and the bending direction of the side walls are different, there is a problem in assembly workability.

In addition, there is known a method in which a sheet member is cut and its periphery is folded in a valley fold to form a holding structure that is raised obliquely, and the side end face of the article is three-dimensionally held by the end face of this holding structure. (For example, see Patent Document 1, especially FIGS. 6 and 7).

Japanese Patent No. 5482355

In the assembly work of such a holding structure, it is usually necessary to separately perform the work of valley folding and the work of processing the holding structure. That is, in the device disclosed in Patent Document 1, the crease to be valley-folded at one end of the obliquely raised holding structure on the lower side and the crease to be valley-folded at the rising side wall are on the same line, These two folds must be made at the same time, and there is a valley-folded fold in the middle of the slanted holding structure due to dimensions, and this fold must be worked separately from the two folds. In addition, the width of the article holding portion due to the oblique holding structure is short.

According to the present invention, by devising the configuration of the obliquely rising holding structure and the valley-folded portion, the holding structure can be assembled simultaneously with the valley-folding process, the holding structure can be easily formed, and the article-holding portion can be formed. To provide a packing material with a long width for holding articles and a method for assembling the packing material.

BEST MODE FOR CARRYING OUT THE INVENTION A packing material for holding articles and a method for assembling the packing material according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a packing material 1 for holding articles. The packing material 1 holds an article to be packed in a packing box, such as a portable wireless device, by contacting a portion of the article, and is formed of a flat rectangular sheet member 2 made of cardboard or the like. The sheet member 2 is assembled according to a predetermined procedure from a state in which it is cut to a predetermined size and subjected to processing such as predetermined cuts, ruled lines for folding, perforations, and the like. It is desirable that the packing material 1 has a rectangular parallelepiped shape as a whole so that it can be easily accommodated in a packing box.

The packing material 1 has a pair of side walls 21 and 22 facing each other with a predetermined gap, and an article holding structure 23 rising obliquely from one side wall 21 (or 22) toward the other side wall 22 (or 21). 24, and a flat portion 25 that connects the pair of side walls 21 and 22 and serves as an article placement surface. In this embodiment, the side walls 21, 22 have outer walls 26, 27 on their outer sides. The sheet member 2 is provided with cuts extending between the pair of side walls 21 and 22 to form the side walls 21 and 22, the article holding structures 23 and 24, and the flat portion 25, and a plurality of folds perpendicular to the cuts. It is Details of the cuts and creases are described in FIG.

The article holding structures 23 and 24 are provided adjacent to the flat portion 25 and straddling between the pair of side walls 21 and 22 . The article holding structures 23 and 24 have rising slopes, and the areas of the end faces 23a and 24a above the plane portion 25 abut against a part (side surface) of the article placed on the plane portion 25. becomes an article holding portion. A space surrounded by the pair of side walls 21 and 22, the article holding structures 23 and 24, and the flat portion 25 serves as a storage space S for storing articles. Since the flat portion 25 is positioned higher than the lower ends of the side walls 21 and 22, the article can be held in a floating state.

In the present embodiment, the article holding structures 23 and 24 are provided respectively on the front side and the rear side of FIG. 1 with the plane portion 25 interposed therebetween in plan view, and are formed so that their rising slopes are alternate. Of the (inner) end surfaces 23a and 24a of the rising slopes of the article holding structures 23 and 24, the areas positioned above the plane portion 25 serve as article holding portions, which are arranged diagonally in plan view. With this configuration, it is possible to prevent rotation of an article placed on the flat portion 25 .

The article holding structure 23 (24) is formed by trough-folding a crease 33 (34) at the lower portion of one side wall 21 (22) to form the lower end, and forming the upper end of the other side wall 22 (21) by the crease 32 (31). ) on the extension line to form a mountain fold 32a (31a) to form the upper end. The plane portion 25 is formed by valley-folding a crease 35 (36) of one side wall 21 (22) above the lower end of the article holding structure 23 (24), and folding the crease 36 on the other side wall 22 (21). (35) is valley-folded.

In this embodiment, the pair of side walls 21 and 22 have creases 31 and 32 at their upper ends and are mountain-folded to have outer walls 26 and 27 on both outer sides. It extends downward from the lower end of 22 and serves as a leg of the packing material 1. - 特許庁

FIG. 2 shows the sheet member 2 before assembly of the packaging material 1 . When corrugated cardboard is used as the sheet member 2, the grain direction is the horizontal direction in FIG. The sheet member 2 is provided with a pair of side walls 21 , 22 , article holding structures 23 , 24 , a flat portion 25 , and outer walls 26 , 27 . Side walls 21 and 22 and article holding structures 23 and 24 are arranged point-symmetrically with respect to the center of flat portion 25 . The outer walls 26 and 27 are positioned on both left and right sides of the pair of side walls 21 and 22 . A plurality of cuts 2c, 2d and creases 31 to 36 are provided to partition these regions.

The cuts 2c and 2d are substantially parallel to the upper and lower sides 2a and 2a of the sheet member 2 in FIG. It is set across. In this embodiment, one (inner) end surface 23a, 24a of the article holding structure 23, 24, which is a rising (or falling) slope, is formed by the cuts 2c, 2d, while the other end surface is formed by a sheet member. The two sides 2a, 2a themselves of 2 are used. Therefore, only one cut 2c (2d) is required to form one article holding structure 23 (24), which improves workability.

The folds 31 to 36 are all substantially parallel to the two sides 2b, 2b of the sheet member 2 perpendicular to the two sides 2a, 2a, that is, provided in a direction perpendicular to the cuts 2c, 2d. The creases 31 and 32 are mountain-folded at the upper ends of the pair of side walls 21 and 22, and the extension of these folds becomes mountain-folds 31a and 32a which are the upper ends of the article holding structures 23 and 24, respectively. The creases 33 and 34 are the lower ends of the side walls 21 and 22, that is, the lower ends of the article holding structures 23 and 24, and are valley-folded. The creases 35 and 36 are portions to be valley-folded to form the plane portion 25, and are provided at positions separated from the creases 33 and 34 in the left-right direction in FIG.

FIG. 3 shows the procedure for assembling the packaging material 1, and FIG. 4 shows the finished assembly of the packaging material 1. FIG. First, the two creases 33 and 34 at the lower portions of the side walls 21 and 22 of the sheet member 2 circled A and B in FIG. 3 are simultaneously valley-folded. The creases 33, 34 consist of stamped creases. The valley folds of the folds 33 and 34 form the lower ends of the article holding structures 23 and 24 and together form the valley folds of the folds 35 and 36 of the planar portion 25 . When a person does the work, the packing material 1 can be valley-folded while holding parts A and B of the packing material 1 with both hands. Also, since there is only one bending point per side, the number of assembly man-hours can be reduced, and since the direction of bending is the same as that of the other points, the work is easy.

Next, the two folds 31 and 32 of the sheet member 2 and the mountain folds 31a and 32a on the extension lines thereof are mountain-folded. Folds 31 and 32 are formed by half-cuts, and mountain folds 31a and 32a are formed by double creases. The upper ends of the side walls 21, 22, the outer walls 26, 27 and the article holding structures 23, 24 are formed by the folds 31, 32 and the mountain folds 31a, 32a.

In this way, the packing material 1 as shown in FIG. 4 can be assembled. When the sheet member 2 is folded, it is not necessary to turn it over or push it up from the back side, and workability is improved. Specifically, it is possible to obtain excellent workability in which the article holding structures 23 and 24 can be easily assembled only by partially processing the valley fold structure, and the advantage of being able to form wide article holding structures 23 and 24. Since the packing material 1 is formed only by the sheet member 2 such as corrugated cardboard, it is excellent in recyclability.

FIG. 5 is a diagram showing a comparison between the packing material 1 of the embodiment (the present invention) and a conventional product (Patent Document 1). A state in which an article P (indicated by a two-dot chain line) is placed on the flat portion 25 of the packing material 1 is shown. Since the holding structure 5P of the conventional product has a crease (54) that becomes the lowest point in the middle of the oblique rise, the article holding portion of the holding structure 5P has a length of L2. On the other hand, the article holding portion of the article holding structure 23 of the embodiment has a length L1, which is longer and wider than the conventional article, and holds the article stably.

FIG. 6 is a diagram showing a comparison between the packaging material 1 of the embodiment (present invention) and other conventional products. The holding structure 5P of the conventional product is shaped so as not to have a crease that becomes the lowest end in the middle of being raised obliquely. , is defective. The reason for such a configuration will be described below with reference to FIGS. 7 and 8. FIG.

FIG. 7 shows the planar dimension (the length in the left-right direction of the drawing) of the packaging material 1 of the embodiment in the developed state, and FIG. 8 shows the side dimension of the packaging material 1 in the assembled state. Here,
The length between the fold line 34 that is the lower end of the article holding structure 24 and the fold line 36 between the side wall 22 of the flat portion 25 is a,
The length of the flat portion 25 is b,
Assuming that the length between the crease 31 that is the upper end of the side wall 21 and the crease 35 between the side wall 21 and the flat portion 25 is c,
The length of the article holding structure 24 is b+c−a, and the relationship shown in FIG. 8 is obtained in the assembled state. Here, according to the Pythagorean theorem, when a is a small value, the lowermost end of the article holding structure 24 having no crease in the middle protrudes outside the side wall 21 like the conventional holding structure 5P shown in FIG. It will be.

In relation to the above matter, the feature of the present invention as a difference from Patent Document 1 is the region of the upper extension of the fold 35 in FIG. There are no creases in the That is, the corrugated board described in Patent Document 1 (especially FIG. 6) is provided with a crease (55), and the crease (55) is folded at the same time as the crease (5b) is folded. need to fold. In contrast, in the present invention, since there is no crease corresponding to the crease (55), the portion corresponding to the crease (54) can be folded at the same time when the portion corresponding to the crease (5b) is folded, thus reducing the number of man-hours. be able to.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, the article holding structures 23 and 24 do not necessarily have rising slopes formed alternately, and may have rising slopes in the same direction. Also, for example, if the lower ends of the side walls 21 and 22 extend to the lower end positions of the article holding structures 23 and 24, the lower ends of the outer walls 26 and 27 do not extend below the lower ends of the side walls 21 and 22. good too.
