Description

  The present invention relates to a packing material for fixing a plate-shaped product such as a printed circuit board, an instruction manual, a CD, an LCD, etc., and storing it in a box, and a packing method for packing a plate-shaped product using the packing material. is there.

In general, the packing material is used to prevent the product from being damaged at the time of storage, transportation, and the like, and a corrugated cardboard having a low cost is used for disposal after use.
Corrugated cardboard packaging material for fixing plate-shaped products, for example, corrugated cardboard is folded into two or more folds to form an impact absorbing pad and positioning guide pad above the plate-shaped product, and absorbs upper and lower shocks. By sandwiching a plate-shaped product (contained item) with an exterior pad and storing it in an exterior case, the impact in the direction perpendicular to the product is absorbed by the upper and lower impact absorbing pads, and the positioning pad or the lower side A positioning piece provided on the upper surface of the shock absorbing pad is known (Patent Document 1) that prevents the movement of the plane including the printed circuit board and absorbs the shock.

  Also, as previously proposed by the applicant of the present invention, a corrugated cardboard is folded to form a bulky cushioning material, and this cushioning material is used by being cut out according to the shape of the stored item. There is also (patent document 2).

  In addition, a product has been proposed in which a corrugated cardboard is bent to form an article storage portion above and below, and when an external force is applied, a projection is formed in the bent portion to abut against the inner surface of the packaging box to enhance the cushioning effect ( Patent Document 3).

  However, the cardboard is folded in two or more to form a shock absorbing pad and positioning guide pad above the plate-like product, and the plate-like product (contained item) is sandwiched between the upper and lower shock absorbing pads. In the case of being housed in an exterior case, since a plurality of members are used, not only the amount of corrugated board to be used is increased, but also a process for assembling each member is required, which reduces workability and increases costs. There was a problem of becoming.

In addition, since the amount of cardboard used to form a plurality of members increases, there is also a problem of going back to resource saving.
Furthermore, when using a positioning pad formed by cutting out the storage hole, the corrugated cardboard of the cut out portion becomes waste, and when providing a small pad, a material for the small pad is also required, There is also a problem that the production work accompanying this is also required.

  In addition, the position of the upper and lower shock absorbing pads is fixed for the first time in a state of being put in the outer case, so when transporting a plurality of products collectively, it is necessary to pack them one by one in the outer case. Since the number of processes is large, there is a problem that the cost is increased.

  Next, if the cardboard paper is folded to form a bulky cushioning material, and the cushioning material is cut and used in accordance with the shape of the stored item, the cut-out portion of the cardboard becomes an extra waste. Therefore, there is a problem in terms of resource saving, and a process of folding and assembling at the time of work is required, resulting in a problem that the number of processes increases.

Then, the cardboard is bent to form the article storage portion up and down, and when an external force is applied, a projection for contacting the inner surface of the packaging box and enhancing the buffering effect is formed on the bent portion. Is folded several times to form the bottom surface and the top surface of the portion for storing the plate-like object such as the instruction manual. For example, since the left and right legs overlap each other, a large amount of cardboard is required, which is uneconomical. At the same time, there is a problem that the workability is lowered due to the folding.
Moreover, the protrusions that are bent and protruded are for abutting against the inner surface of the packaging box when an external force is applied to enhance the cushioning effect, and the stored plate-like object easily shifts and cannot be fixed. There was also a problem.

Because the clamping piece protrudes,
There is an advantage that the assembly work can be done quickly with a simple operation that only causes folding, and the work efficiency can be improved.
In addition, by folding the leg-forming surface, it is possible to set the article to be stored in the box simply by placing the article between the sandwiching pieces protruding from the article placing surface, and the setting work can be done easily without any trouble. There are also benefits that can be done

  Further, the leg forming surface is elastically restored by simply folding the leg forming surface and storing the article in a state where the article is placed between the sandwiching pieces protruding from the article placing surface, and the lower end of the leg forming surface is restored. Since the angle between the leg forming surface and the article placement surface is received by the corner of the box and becomes obtuse, the sandwiching piece comes into contact with the article and the article is securely fixed. Is unnecessary, and there is an advantage that workability can be greatly improved.

The most preferred embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a box 1, a printed board, an instruction manual, a CD, an LCD, or other plate-like article (product) 2 accommodated in the box 1, and the article 2 accommodated in the box 1 in a fixed position. FIG. 3 is an exploded perspective view showing a packing material 3.
The box 1 is formed in a rectangular container shape that is open on one side with a sheet material such as cardboard or cardboard, and cardboard is used in this example.

As shown in FIGS. 1 and 2, the packing material 3 is formed with a rectangular article placement surface 4 at the center, and mountain folds indicated by dotted lines on the upper and lower sides and the left and right sides of the article placement surface in the figure. Leg forming surfaces 7 and 9 are formed via lines 5 and 6, respectively, and the length of the leg portion 8 of the leg forming surface 7 formed on the upper and lower side portions is a, and is formed on the left and right side portions. The length of the leg portion 10 of the leg portion forming surface 9 is b, and the distance between the end of the article mounting surface 4 and the glue in the box 1 (the protruding length of the protruding piece 11 for preventing the lateral movement described later) ) Is set to c, so that b = √ (a2 + c2).
On the leg forming surfaces 9 formed on the left and right side portions, a clamping piece 12 for clamping the plate-like article 4 from the left and right protrudes inward of the article placement surface 4 beyond the mountain fold line 6. In addition, it is integrally formed in a state extended from the leg forming surface 9 and, of course, the mountain fold line 6 is not formed in the sandwiching piece 12 portion as shown in FIG.

Reference numeral 11 in the figure denotes a projecting piece for preventing the lateral movement in the figure when the packing material 3 is inserted into the box 1 from the opening formed on one side and stored. The length L between them is substantially equal to the left and right glue L1 of the box 1, and the projecting pieces 11 near the upper and lower ends are integrally extended in a state of being extended from the article placement surface 4, and the inner projecting pieces 11 are It is integrally formed in a state extended from the article placement surface 4 by a cut line formed in a state of projecting from the article placement surface 4 to the leg forming surface 9 beyond the mountain fold line 6. As in the case of the piece 12 portion, the mountain fold line 6 is naturally not formed in the protruding piece 11 portion (see FIG. 2).
Further, when the packaging material 3 is stored in the box 1, the movement of shifting in the L3 direction (vertical direction) in FIG. 1 is prevented between the upper and lower ends of the article placement surface 4 (upper and lower mountain fold lines 5. 5) is made substantially equal to the length L3 of the glue on the top and bottom of the box.

  Reference numeral 13 denotes a positioning piece for positioning the plate-like article 2 placed on the article placement surface 4 in the vertical direction, which is indicated by a U-shaped cut line 14 and a two-dot chain line on the cut line 14. A valley fold line 15 and a dotted mountain fold line 16 are provided, and the interval between the valley fold line 15 and the mountain fold line 16 is set in accordance with the thickness of the plate-like article 2 placed on the article placement surface 4. is there.

Each of the score lines 14, the mountain fold lines 5, 6, 16 and the valley fold line 15 has two legs that are perpendicular to the corrugated corrugated cardboard formed by forming corrugated paper between a pair of kraft paper. When the packaging material 3 is die-cut into a shape as shown in FIG. 2 by a punching device (not shown) such as Thomson so as to be positioned between the part forming surfaces 9 and 9 (left and right in FIG. 2). Formed simultaneously.
That is, when the entire shape is punched, the cut line 14 is cut, and the mountain fold lines 5, 6, 16 and the valley fold line 15 in this example crush the corrugated cardboard to reduce the thickness and make it easier to bend. It is.
The mountain fold lines 5, 6, 16 and the valley fold line 15 can be easily bent by perforation or half-cutting.

  Incidentally, a corrugated cardboard in which a kraft paper formed into a corrugated shape is provided between a pair of kraft papers has a high buckling resistance against muscles orthogonal to the corrugated structure, so that it is orthogonal to the corrugated shape as in this example. When punching is performed so that the streak is positioned between the leg forming surfaces 9 and 9, the buckling force of the projecting piece 11 and the sandwiching piece 12 that prevent the lateral movement is increased.

Next, a procedure for packing the plate-shaped article 2 such as a printed board, an instruction manual, a CD, and an LCD with the packing material 3 formed as described above will be described.
First, the sheet-like packing material 3 from which cardboard is punched as shown in FIG. 2 folds the positioning piece 13 and, as shown in FIG. 3A, peaks formed on the four sides of the article placement surface 4. The leg forming surfaces 7 and 9 are bent to the back side of the packing material 3 at the folding lines 5 and 6 to form the leg portions 8 and 10.
Then, the clamping piece 12 integrally formed in the state extended from the leg part formation surface 9 will be in the state protruded from the article mounting surface 4 (refer FIG.1 and FIG.3 (b)).

Next, in a state where the plate-like article 2 is positioned by the positioning piece 13, the plate-like article 2 is placed on the article placement surface 4 between the left and right sandwiching pieces 12 and 12, and the packaging material 3 is stored in the box 1 together with the plate-like article 2. To do.
The left and right leg portions 10 of the packaging material 3 housed in the box 1 together with the plate-like article 2 are gradually bent and elastically restored when the packaging material 3 is housed in the box 1. As shown in FIG. ), The lower end of the leg 10 is received by the corner of the box 1.

Here, when the lower end portion of the leg portion 10 is received by the corner portion of the box 1, the angle θ between the leg portion forming surface 9 and the article placement surface 4 is 135 degrees (the angle between the sandwiching piece and the article placement surface). It is desirable to set a.b.c so that a.apprxeq.c so that .theta.1 is 45 degrees.
That is, when the angle θ between the leg portion forming surface 9 and the article placement surface 4 is 135 degrees, the load on the article placement surface 4 acting on the bottom surface and the side surface from the corner portion of the box 1 via the leg portion 10 The impact force is evenly distributed, and the leg 10 has the strongest angle for buckling.
As described above, the plate-like article 2 can be securely fixed without being displaced only by being housed in the box 1 in a state of being sandwiched by the sandwiching pieces 12 on the article placement surface 4 of the packing material 3.

Moreover, when taking out the plate-shaped goods 2 accommodated in the box 1, the packing material 3 is taken out from the box 1, and the leg part 10 is folded in the back side of the goods mounting surface 4 so that the edge parts may adjoin. The plate-like article 2 can be taken out simply.
Thereby, the effort at the time of packing work or opening can be reduced.
On the other hand, the packing material 3 after taking out the plate-shaped article 2 can be processed without being bulky when the mountain-folded portion is turned back into a valley fold to form a sheet as shown in FIG.

In this example, the end of the leg 10 is received by the corner of the box 1, but the corner of the box 1 referred to in the present invention is not necessarily the corner formed by the bottom and side walls of the box 1. 4 and includes a corner formed by the upper surface and the side wall of the stored item 17 such as an instruction manual or a pamphlet stored in the bottom of the box 1 as shown in FIG.
Further, in this example, the protruding piece 11 is shown as having three positions formed on both sides and the leg portion forming surface 9 portion on the one side, but as shown in FIG. Except for the case of overlapping packaging, the projecting pieces 11 may be provided at least at both ends.
5 is one in which a plurality of packaging materials according to the present invention are stacked in one box 1 and packaged, and in this case as well, a plate-like material placed on the article placement surface 4 of each packaging material 3 is used. The effect | action and effect that an article | item is fixed in the state positioned firmly like the above-mentioned is not impaired.
In such a case, the lower end of the upper leg portion 10 is received by the projecting piece 11 located below, so that the projecting piece 11 is not provided with the leg portion 8 formed on both upper and lower sides and vertically bent. It is necessary to be formed in the leg forming surface 9, and it is desirable that the width is long from the viewpoint of strength, or a plurality of them are formed.

In the above embodiment, the plate-like article 2 is rectangular, but for example, when the shape of the plate-like article 2 is polygonal or one side is arcuate, it is shown in FIG. Thus, it can respond by forming one side of the article placement surface 4 in a polygonal shape.
In the above embodiment, the packaging material 3 is formed of corrugated cardboard as a desirable embodiment. However, the present invention is not limited to this, and it is needless to say that it can be formed of a foamed synthetic resin sheet or the like. It is not.

  By the way, in the case where an opening for putting in / out an article is provided on one side of the box 1 as in the above embodiment, when the product inside is taken out, even if the opening of the box 1 is opened and directed downward, Since the lower end of the leg of the packing material is in contact with the corner of the box, it will not come out unless it is picked up by the packing material.

These are exploded perspective views when packing using the packing material concerning this invention. FIG. 3 is a front view of the developed packing material according to the present invention. These are the schematic diagrams which show the procedure which uses the packing material concerning this invention. These are sectional drawings which show the outline of an example packed using the packing material concerning this invention.
