Description

  The present invention relates to a technique for forming an article holding 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 article holding material.

2. Description of the Related Art Conventionally, for example, a box-shaped packing material is formed by folding a plate-like corrugated cardboard with a crease 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 valley-folded at a valley fold 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 such as an electronic device is stored in a space surrounded by the two surfaces of the packaging material 200. The valley fold 110a is set in a direction perpendicular to the corrugated cardboard of the corrugated cardboard 100.
At this time, an article holding structure 400 is formed in order to prevent the stored article 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.

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

Since the fold 140 in FIG. 10 is a mountain fold in the state of FIG. 11, in order to facilitate the assembly operation, the crease 140 may be formed from the back surface to facilitate the mountain fold. While desired, for this purpose, the two folds 130, 130 front putting creases from the valley fold lines 110a, then, Heck et cardboard 100 is inside out reversed, complex step of providing said fold line 140 is required.
In addition, two molds for forming the creases are necessary for forming the two folds 130 and 130 and the valley fold 110a and for forming the crease 140, which increases the processing cost.
In addition, the work of pushing out the region sandwiched between the two cuts 120 and 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.
Note that the crease 140 is easy to assemble by providing a cut that does not penetrate, but the cardboard is likely to be cut at that portion, and is not appropriate particularly when strength is required or the width is narrow. .

In order to solve the above-mentioned problems, an object of the present invention is to provide a technique capable of easily forming an article holding structure when a packaging material is formed by bending a sheet member such as a plate-like cardboard. The applicant has already filed a patent application in Patent Document 2.
As shown in FIGS. 12, 13, and 14, the invention according to the patent application

The valley fold line 501c is formed outside the two cuts 531,532,
The sheet member 500 is folded at the valley fold line 501c, whereby the region 503P surrounded by the two cuts 531 and 532 and the two fold lines 534 and 536 is raised obliquely to form an oblique article holding structure. This is a featured invention.
Further, the present invention further includes forming folds 533 and 535 parallel to the two folds 534 and 536 at both ends of the two cuts 531 and 532, respectively.

  In the invention, as shown in FIG. 13, the sheet member is bent at the valley crease so that the region surrounded by the two cuts and the two folds rises diagonally, thereby forming an oblique article. As shown in FIG. 14, since the portions D1 and D2 bent by the two folds 534 and 536 protrude outward from the two surfaces 510c and 510d at two locations as shown in FIG. The protrusions D1 and D2 have a problem that it interferes with the arrangement of other members, for example, other sheet members.

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 constructing an article holding material for storing articles with the cardboard 1 will be described.

First, the corrugated cardboard 1 is provided with valley folds 1a, 1b, 1c indicated by three broken lines. The corrugated board 1 is divided into four surfaces 10a, 10b, 10c, and 10d by these three valley folds. The valley folds are formed in a direction perpendicular to the corrugated board of the corrugated board 1. The valley crease 1c corresponds to the first crease described in the claims.
Next, in the case of forming two article holding structures, notches and folds 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 crease 1c will be described with reference to FIGS.
First, a cut 31 perpendicular to the valley fold 1c is made at a predetermined position where an article holding structure is to be formed. The cut 31 is a cut that penetrates 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 cut 31 and one end of the cut 32 is formed. Next, a fold line 35 connecting the other ends of the notches 31 and 32 and a fold line 34 inside thereof are formed in parallel to the fold line 33.
The fold line 34 is provided at a position that does not overlap the extended line of the valley fold lines 1b and 1c. In the case of FIG. 1, it is provided at a position close to the fold 35.
The crease 35 is also provided at a position that does not overlap the extended line of the valley creases 1b and 1c.

At this time, it is desirable that the folds 33 and 34 are folds that are easy to fold in the valley, and the crease 35 is folds that are easy to fold, but such processing takes time, so both are simply crushed and formed. A crease is sufficient.
The fold line 33 corresponds to the third fold line described in the claims,
The fold line 34 corresponds to a second crease set forth in the claims;
The fold 35 corresponds to a fourth fold described in the claims.

What is important here is that the valley crease 1c is not formed in the region 3P sandwiched between the two cuts 31 and 32, but only on the outside of the region 3P.
Here, the region 3P sandwiched between the two cuts 31 and 32 and the two folds 33 and 34 is the force applied to the region 3P when folded at the valley fold 1c (corrugated cardboard in this embodiment). It is necessary to form a plate-like region that cannot be bent easily by the force applied in the direction of.
As described above, cuts and folds for forming one article holding structure are formed. Similar notches and folds are formed in the vicinity of the valley fold 1c and at different positions, and the article holding structure is formed at another position.

As described above, in addition to the three valley folds 1a, 1b, and 1c, the corrugated cardboard 1 in which the cuts and folds for forming the two article holding structures are formed as shown in FIG. The article holding material is assembled by folding the valleys at the valley folds 1a, 1b, and 1c.
At this time, a process in which one article holding structure is formed in the vicinity of the valley fold 1c will be described with reference to FIG.
FIG. 3A shows a perspective view of the main part in a state before the valley fold 1c is folded, and FIG. 3B shows the main part in a state where the valley fold 1c is slightly folded. FIG. 3C shows a perspective view of a main part in a state where corners are formed by perpendicularly folding the valley folds 1c, and FIG. 3D shows the valley folds. Side surface sectional drawing of the principal part of the state folded at right angles by 1c is shown.

  As shown in FIG. 3B, when a force is applied from the outside and the valley fold 1c is slightly folded at the valley fold 1c, the two surfaces 10c and 10d of the corrugated cardboard approach each other. Is closer to the state shown in FIG. However, as described above, the region 3P sandwiched between the two folds 33 and 34 has a force applied to the region 3P when it is bent at the valley fold 1c (in this embodiment, a force applied in the direction of the corrugated board). Then, since it is a plate-like region that cannot be bent easily, the fold line 34 naturally buckles to form a valley fold, the fold line 33 naturally buckles to form a valley fold, and the fold line 35 naturally buckles. As shown in FIGS. 3C and 3D, the region 3P sandwiched between the two folds 33 and 34 is naturally inclined at the corner near the valley fold 1c. The slanted article holding structure 3 can be easily formed at the corners formed on the two adjacent surfaces 10c and 10d simply by applying the force for arranging and valley folding.

Similarly, the article holding structure 4 at another position is also formed.
In this way, as shown in FIG. 4, the article holding material 2 in which the article holding structures 3 and 4 are formed at two places is completed.
Hereinafter, a case will be described in which the article holding member 2 holds the article 7 such as an electronic component having a shape as shown in FIG. 5A as shown in FIG. 4 and 5, the same reference numeral 3 </ b> P is attached to the region formed in the two article holding structures 3 and 4 for convenience of explanation.
The article 7 includes a main body 72 provided with a protrusion 71 such as an antenna.

  When the article 7 is held at a predetermined position using the article holding material 2, the main body 72 is placed between the article holding structures 3 and 4 formed at two locations, and the main body 72 is The two surfaces 10c and 10d and the two article holding structures 3 and 4 are brought into contact with each other and are held at predetermined positions. At this time, since the space S surrounded by the region 3P and the two adjacent surfaces 10c and 10d is formed in the article holding structure 3, the protrusion 71 of the article 7 is formed in the space S. Can be inserted and held.

  In this manner, the article 7 is stored in a state where the surface of the article 7 is in contact with the two surfaces 10c, 10d and the article holding structures 3, 4 formed at the two locations. The stored article 7 is held at a predetermined position in contact with the two surfaces 10c and 10d and the article holding structures 3 and 4 formed at the two locations, so that it is inclined during transportation. Even if it is moved or moved, the article 7 can be safely transported without shifting. Further, even when the article 7 has the protrusion 71, the protrusion 71 can be held in the space S. Therefore, the protrusion 71 can be prevented from being damaged, and the position where the article 7 is held can be easily positioned. Therefore, it can be held securely.

  According to the present invention, an oblique article holding structure can be formed by simply applying a trough folding force to a corrugated cardboard having a predetermined cut and crease as described above. Compared to forming a rectangular article holding structure, the article holding material on which the article holding structure is formed can be easily assembled.

Further, when the region 3P becomes longer, the region 3P is easily deformed. In the case of the region 3P, as shown in FIG. 3C, the side edges 31P and 32P are formed on the surface of the cardboard. Since it is held by the end faces of the notches 31 and 32 of 10c, sufficient strength can be obtained. Therefore, the article 7 can be held with sufficient strength.
Thus, since the strength is ensured even if the region 3P is lengthened, the space S on the back side of the region 3P can be secured widely, and the space S projects like a projection of the article 7 or the like. The inserted portion can be inserted and held with sufficient strength.

Further, a mountain fold portion of the fold line 34 projects below the cardboard surface 10c, but does not project outside the cardboard surface 10d. A plurality of cardboards can be stacked to reinforce the cardboard surface 10d. In addition, a gap divided into a plurality of parts is formed by the mountain folds of the fold line 34 below the surface 10c of the corrugated cardboard, so that accessory parts and the like of the article 7 can be accommodated in the gap. .

As shown in FIGS. 6 and 7, in Example 2, the corrugated cardboard 5 was provided with valley folds 5a, 5b, 5c indicated by three broken lines. The corrugated board 5 is divided into four surfaces 50a, 50b, 50c, 50d by these three valley folds. The valley folds were formed in a direction perpendicular to the corrugated board of the corrugated board 5.
In the first embodiment described above, the valley folds 1b, 1c of the cardboard 1 are arranged so as not to overlap the extended line of the fold 35, but in the second embodiment shown in FIGS. It arrange | positioned so that another valley crease | fold 5b of the cardboard 5 might overlap on an extension line.
6 and 7, 51 and 52 correspond to two cuts, 54 corresponds to the second fold, 53 corresponds to the third valley fold, and 55 corresponds to the fourth fold.
The valley fold 5b corresponds to the fifth fold.

In FIG. 6, reference numeral 57 denotes a U-shaped cut formed in a U-shape that is formed sideways from the surface 50b of the cardboard 5 to the surface 50c side without providing a crease in a part of the other valley fold 5b. is there. The other valley fold 5b is not formed between the start end and the end of the cut 57.
58 is a U-shaped cut formed in a U-shape that does not have a crease in a part of the valley crease 5c, and is formed in the portion from the surface 50d of the corrugated board 5 to the surface 50c side. The valley fold 5c is not formed between the start end and the end of the cut 58.

In this case, as shown in FIG. 7, in the article holding material 6 formed from the corrugated cardboard 5, both the fold line 55 and the valley fold line 5b are valley-folded on the same line. Whereas the fold line 55 is folded at an obtuse angle, it is folded.
In the article holding material 6, an article holding structure 56 for holding the article is formed at the corners by the region 5 </ b> P formed obliquely. Further, a protrusion or the like can be stored in the space 5S formed on the back side of the region 5P.

When the cardboard 5 is folded at the valley fold 5b, the U-shaped notch 57 is not valley-folded. Therefore, as shown in FIG. 7, the leg-like member 57a extends downward from the surface 50b of the cardboard. Form.
When the cardboard 5 is valley-folded at the valley fold 5c, the U-shaped cut 58 is not valley-folded. Therefore, as shown in FIG. 7, the leg-like member 58a extends downward from the cardboard surface 50d. Form.
By configuring the two leg-shaped members 57a and 58a to have the same height as that of the portion formed by the fold line 54, the article holding member 6 is made to be the two leg-shaped members. 57a, 58a and the fold line 54 can be made independent as legs. And the accessory of articles | goods etc. can be accommodated in the clearance gap formed in the lower side of the cardboard surface 50c.

The first embodiment corresponds to the second and fifth aspects, and the second embodiment corresponds to the third and sixth aspects. The third embodiment corresponds to the first and fourth aspects. Will be described with reference to FIGS.
As shown in FIGS. 8 and 9, the third embodiment is different from the first embodiment in that only the fold line 34 is provided without providing the fold lines 33 and 35. That is, since the third and fourth folds are not provided, as shown in FIG. 9, a corner is not formed at the boundary portion between the region 30P constituting the article holding structure 30 and the cardboard surfaces 10c and 10d. It is a point that transforms into
In FIGS. 8 and 9, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
In the case of Example 3, the effect that the effort which forms a crease decreases can be acquired.

Any number of the article holding structures according to the present invention may be provided in one article holding 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. Further, the notches and folds for forming the article holding structure having the above-described configuration can be processed using a conventional standard single-sided corrugated board processing apparatus, 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 an article holding material using cardboard, and can be applied to various structures.

The first fold is formed outside the two cuts and at a position that does not overlap the extension line of the second fold,
The Rukoto the sheet member is valley-folded at the first fold, along with the angle portion is formed, the second fold line and said third fold line are valley fold, the fourth fold mountain are folded, characterized in that said two incisions and the second fold line and the third fold line and in enclosed or areas of the is turned up is to become article retention structure stood obliquely in front Symbol corner Goods holding material. An article holding structure for holding at least a part of an article to be packed in contact with corners formed by two adjacent surfaces by folding a flat plate-like sheet member at a first fold. Is an article holding material formed,
The article holding structure is
In the sheet member, the two cuts at an arbitrary interval, the second fold line perpendicular to the cuts between the two cuts, and the cuts between one end of the two cuts. a third fold line which is perpendicular to, among other end of the cut of the two, and the fourth fold line perpendicular to the incision, and said parallel first fold on the extension of the fourth fold line a fifth fold, is formed,
The first fold is formed outside the two cuts and at a position that does not overlap the extension line of the second fold,
When the sheet member is valley-folded at the first fold, the corner portion is formed , and when the sheet member is valley-folded at the fifth fold, the second fold and the third fold are formed. the fourth of the folds are valley-folded, the two notches and the second fold line and a third region surrounded by the folds are thus raised obliquely to the corner article retaining structure and object article holding member it wherein a is.
