Description

  The present invention relates to a technique for forming a packaging material by bending a sheet member such as a plate-like cardboard, and more particularly to a technique for easily forming an article holding structure on the packaging material.

2. Description of the Related Art Conventionally, for example, a box-shaped packing material is formed by folding a plate-like cardboard by providing a folding line or a cut. Such a packing material is disclosed in Patent Document 1 and the like.
A general example will be described with reference to FIGS.
Reference numeral 100 denotes a plate-like corrugated cardboard, and a basic procedure for constructing a packaging material 200 for holding and storing articles with the corrugated cardboard 100 will be described.

First, the corrugated cardboard 100 is folded at a valley fold line 110a indicated by a broken line to form, for example, a bottom surface 100a and a right side surface 100b to form a packaging material 200 as shown in FIG. Then, an article 300 such as an electronic device is stored in a space surrounded by the two surfaces of the packing material 200. The valley fold line 110a is in a direction perpendicular to the corrugated board of the corrugated board 100.
At this time, an article holding structure 400 is formed in order to prevent the stored article 300 from shifting in the space in the packaging material 200. A plurality of the article holding structures 400 may be provided at positions corresponding to the outer dimensions of the article 300.

In order to configure one article holding structure 400 from the one sheet-like cardboard 100, the cardboard 100 includes, for example, two pieces perpendicular to the valley fold line 110a as shown in FIG. Notches 120 and 120 are provided. Further, fold lines 130 and 130 connecting both ends of the two cuts 120 and 120 and a fold line 140 parallel to the valley fold line 110a are provided.
In this manner, the corrugated cardboard 100 provided with the cut and fold line is bent at the valley fold line 110a to form a space by bending the bottom surface 100a and the right side surface 100b at right angles, and then sandwiched between the two cuts 120 and 120. The formed region is pushed out to the space side to form an article holding structure 400 having a rectangular cross section as shown in FIG.

Since the fold line 140 in FIG. 7 is a mountain fold in the state of FIG. 8, in order to facilitate the assembly work, the fold line 140 is formed with a fold line from the back surface to facilitate the mountain fold. For this purpose, the two fold lines 130, 130 and the valley fold line 110a are folded from the front side, and then the corrugated board 100 is turned upside down before the fold line 140 is provided. Is required.
In addition, two molds for forming the fold line are required for forming the two fold lines 130 and 130 and the valley fold line 110c, and for forming the fold line 140, which increases the processing cost. is there.
In addition, the work of pushing out the region sandwiched between the two cuts 120, 120 to form such a rectangular article holding structure is a work that requires a great deal of force on the fingertip, and forms a large number of article holding structures. To do was a very painful task.
The folding line 140 is easy to assemble by providing a cut that does not penetrate, but the corrugated cardboard is easy to break at that part, and is not appropriate especially when strength is required or the width is narrow. is there.

In FIG. 1 showing an embodiment for carrying out the article holding structure forming method according to the present invention,
Reference numeral 1 denotes a plate-like cardboard as a sheet member as a raw material, and a basic procedure for constituting a packaging material for storing articles with the cardboard 1 will be described.

First, the corrugated cardboard 1 is provided with valley fold lines 1a, 1b, and 1c indicated by three broken lines. The corrugated board 1 is divided into four surfaces 10a, 10b, 10c, and 10d by these three valley fold lines. The valley fold line is formed in a direction perpendicular to the corrugated board of the corrugated board 1.
Next, in the case of forming two article holding structures, notches and fold lines for forming the article holding structure are formed at two predetermined locations on the cardboard 1 as follows.

Hereinafter, the case where one article holding structure 3 is formed in the vicinity of the valley fold line 1c will be described with reference to FIGS.
First, a cut 31 perpendicular to the valley fold line 1c is made at a predetermined position where an article holding structure is to be formed. This notch 31 is a notch penetrating to the back surface.
A notch 32 parallel to the notch 31 is similarly provided. The interval between the two cuts may be appropriately determined according to conditions such as strength required for the article holding structure to be formed. These cuts need to extend over both sides of two adjacent surfaces 10c and 10d of the cardboard.

  Next, a fold line 33 that connects one end of the notch 31 and one end of the notch 32 is formed. Further, a similar fold line 34 is formed parallel to the fold line 33 and slightly inside the fold line 33 (on the valley fold line 1c side). At this time, it is desirable that the fold line 33 is a fold line that is easy to fold, and the fold line 34 is a fold line that is easy to fold. The formed fold line is sufficient.

Next, a fold line 35 connecting the other ends of the notches 31 and 32 and a fold line 36 inside the fold line 36 are formed in the same manner.
What is important here is that the valley fold line 1c is not formed in the region 3P sandwiched between the two cuts 31 and 32 but formed only outside.
Here, the region 3P sandwiched between the two cuts 31 and 32 and the two fold lines 34 and 36 has a force applied to the region 3P when folded at the valley fold line 1c (in this embodiment, It is necessary to have a plate-like region that cannot be easily bent by the force applied to the direction of the corrugated board.
As described above, a cut and a fold line for forming one article holding structure 3 are formed. Similar cuts and fold lines are formed in the same manner at positions where other article holding structures 4 are formed.

As described above, in addition to the three valley fold lines 1a, 1b, and 1c, the corrugated cardboard 1 in which the cuts and fold lines for forming the two article holding structures are formed as shown in FIG. The packing material is assembled by valley folding at the three valley fold lines 1a, 1b, and 1c.
At this time, a process in which one article holding structure 3 is formed in the vicinity of the valley fold line 1c will be described with reference to FIG.
FIG. 3A is a side sectional view of the state before the valley fold line 1c is folded, and FIG. 3B is a side sectional view of the state where the valley fold line 1c is slightly folded. FIG. 3C shows a side cross-sectional view in a state where the valley is folded at a right angle along the valley fold line 1c.

As shown in FIG. 3B, when a force is applied from the outside and the valley fold line 1c is slightly folded, the two surfaces 10c and 10d of the corrugated cardboard approach each other. The distance to the lines 35 and 36 is closer than the state shown in FIG. However, as described above, the region 3P sandwiched between the two fold lines 34 and 36 has a force applied to the region 3P when folded at the valley fold line 1c (in this embodiment, in the direction of the corrugated board). Such a force) is a plate-like region that cannot be bent easily, so that the fold lines 33 and 35 at both ends naturally buckle to form a mountain fold, and the inner fold lines 34 and 36 naturally buckle. As shown in FIG. 3C, a region 3P sandwiched between the two fold lines 34 and 36 is naturally inclined in the vicinity of the valley fold line 1c, The article holding structure 3 is naturally formed only by applying a force for folding.
Depending on the situation, it may buckle in the state of (D) in FIG. 3 or it may be folded at one side as in (E) of FIG. 3, but in any case, only the force for folding the valley is applied. Thus, the oblique article holding structure 3 is formed almost naturally.

Similarly, other article holding structures 4 are also formed.
In this way, as shown in FIG. 4, the packaging material 2 in which the article holding structures 3 and 4 are formed at two places is completed. The packing material 2 is the packing material described in claims 3 and 4.
When the article 7 such as an electronic component is stored in the packing material 2, the article 7 is stored with the article 7 sandwiched between the article holding structures 3 and 4 formed at the two locations. Since the stored article 7 is held between the article holding structures 3 and 4 formed at the two locations, even if it is tilted or moved during transportation, the article does not receive a large impact. The article can be safely transported.
According to the present invention, as described above, an oblique article holding structure can be formed by simply applying a trough folding force to a corrugated cardboard having a predetermined cut and fold line. Compared to the case of forming such a rectangular article holding structure, the packaging material on which the article holding structure is formed can be easily assembled.

In the first embodiment described above, four folding lines are provided when forming one article holding structure. However, the folding lines are not limited to four, and if there are two or more folding lines, three folding lines are also possible. It may be 5 or more. The cardboard used is not limited to paper but may be plastic.
FIG. 5 shows the cardboard 5 in the case where two folding lines are formed. As shown in this figure, two fold lines 53 and 54 are formed slightly inside both ends of the two cuts 51 and 52. The fold lines 53 and 54 are preferably valley folds. In this way, when the corrugated cardboard 5 in which only two folding lines are formed is folded along the valley folding line 5c, it is surrounded by two notches 51 and 52 and two folding lines 53 and 54 as shown in FIG. Since the region 5P is a plate-like region that is not easily folded, similarly to the region 3P in the first embodiment, a force is applied to the two folding lines 53 and 54 in the direction of valley folding. The valley is folded. Therefore, the area outside the two fold lines 53 and 54 is deformed to be in the state shown in the figure, and the area 5P surrounded by the two fold lines 53 and 54 is arranged obliquely, so that the article holding structure 6 is formed. It is formed naturally.

When the lengths of the cuts are the same, the distance between the two folding lines 34 and 36 in the article holding structures 3 and 4 of the first embodiment is the distance between the two folding lines 53 and 54 in the article holding structure 6 of the second embodiment. Since it can be made wider, there is an effect that the article holding structures 3 and 4 of the first embodiment are more suitable for fixing a large article.
On the contrary, the article holding structure 6 of the second embodiment has an effect that the processing of the folding line is less.

Any number of the article holding structures 3, 4, 6 having the above-described configuration may be provided in one packing material.
As described above, according to the present invention, since the article holding structure can be formed very easily, excellent work efficiency can be obtained. In addition, the notches and fold lines for forming the article holding structure having the above-described structure can be processed using a conventional standard cardboard processing apparatus from one side, and therefore can be implemented at low cost.
In addition, it can replace with the said cardboard and can use various plate-shaped sheet | seat members.

The present invention is not limited to packaging materials using cardboard, and can be applied to various structures.
