Next, an example of the procedure for folding the packing material 200A from the cardboard 100A will be described with reference to FIGS.
[0021]
First, as shown in FIG. 3, each of the four side wall surfaces 3 and 4 is raised along the fold.
Next, the spacer piece 9 straddling between both side end portions of the upper edge of one side wall surface 4 is bent horizontally inward and then bent downward in a shallow V shape.
As a result, as can be understood from FIG. 3, the spacer piece 9 is brought into contact with a substantially central region outside the side wall surface 4.
[0022]
Next, as shown in FIG. 4, the support piece 13 connected to the bottom plate 11 is bent downward and the reinforcing piece 14 is bent upward.
In this state, the inner bottom plate 11 and the wall surface 12 for hanging are bent inward along the fold lines O and N, respectively, and the hanging wall 12 is moved to the side wall surface as shown in FIGS. 4, the inner bottom plate 11 is bridged between the upper edge portions of the opposed inclined bottom surfaces 2 and 2.
At this time, if the insertion protrusion 13a is inserted into the insertion hole 15, the above-described bending operation can be easily performed, and the bending form is securely fixed.
[0023]
As shown in FIGS. 6 and 7, the inner box-shaped packing material 200A, which is easily and quickly folded in this way, is tightly fitted in a cardboard packaging box 300, and then the box The packing article 400 is stored in the inner space.
[0024]
Subsequently, as shown in FIG. 7, the component storage case 500 is fitted into a gap intentionally provided between the upper surface of the packing material 200 </ b> A and the lid surface 300 a of the packing box 300, and the lid is closed. For example, the folding operation of the packing material 200A and the packing operation of the packed article are completed extremely easily and reliably.
[0025]
As another method for folding the packing material A, first, the opposing side wall surfaces 3 and 3 of the corrugated cardboard 100A in the unfolded state are raised, and the bent pieces 7 and 7 are directed downward toward the outside. The state is bent into an L shape (see FIG. 4).
[0026]
When the corrugated cardboard 100A in this state is pushed into the packaging box 300 with the lid open, the other side wall surfaces 4 and 4 facing each other are also erected from the self, so that the packing 200A can be folded and packed. The fitting operation into the box 300 can be performed quickly and efficiently.
[0027]
The packed article 400 packed as described above is extremely well buffered and supported between the upper edges of the pair of inclined bottom surfaces 2 and 2 (see FIG. 7).
In addition, the middle bottom plate 11 installed between the upper edge portions of the inclined bottom surfaces 2 and 2 plays a role of further improving the above-described buffer support function.

That is, as understood from FIGS. 5 to 7, the bottom plate 11 in contact with the bottom surface of the packaged article 400 is supported by one of the four sides by the wall 12 for vertical support. Are supported by the support piece 13 and the reinforcing pieces 14 and 14 connected to the remaining two sides serve to prevent the deformation of the midsole plate 11.
Therefore, even when a very strong drop impact force is exerted on the packaging box 300, the buckled deformation of the inclined bottom surfaces 2 and 2 is prevented, and the packaged article is reliably protected.
[0029]
And as for the impact force exerted on the packing article 400 from the side surface direction, the impact force in the direction of the side wall surface 3 is surely absorbed by the bent piece 7 bent in the downward L-shape that continues to the outside. Is done.
For particularly strong impact force, the top surface 7a buckles at the position of the buckling fold 8, and this impact force is sufficiently attenuated.
[0030]
As for the impact force in the direction of the side wall surface 4, as shown in FIG. 5, the sleeve wall surfaces 5, 5 connected to both ends of the side wall surface 4 are inclined obliquely outward, and the side wall surface 4 protrudes inward. Therefore, the side wall surface 4 and the sleeve wall surfaces 5 and 5 work together to exhibit a very effective buffer function.
[0031]
In addition, as shown in FIG. 5, the spacer piece 9 abutted over a wide range in the middle of the outer side surface of the side wall surface 4 bent into a V shape better exhibits the buffering effect. .
[0032]
Further, for the impact force exerted from above the packaging box 300, the cardboard component storage case 500 placed on the packaging article 400 serves as an effective cushioning material.
[0033]
Next, FIGS. 8-10 is explanatory drawing of the other Example of this invention.
The packing material 200B of this embodiment shown in FIG. 10 is folded from the single cardboard 100C shown in FIG. 8 to the form shown in FIG. 9, and the auxiliary packing 200C is attached. Yes.
[0034]
The first difference that the packing material 200B of the second embodiment is different from the packing material 200A of the first embodiment is that the inner bottom plate 11 is separated from the main body of the packing material 200B to be separated.
The second difference is that the spacer pieces 9 are continuously provided on both of the pair of opposing side wall surfaces 4 and 4.
[0035]
As shown in FIG. 8, the corrugated board 100B is different from the corrugated board 100A in that the middle bottom plate 11 and the wall 12 for hanging support are omitted, and instead, the left side wall 4 in the figure is also left side. In the same manner as the side wall surface 4 of FIG.
[0036]
As shown in FIG. 8, the corrugated cardboard 100 </ b> C has a configuration in which the support piece 13 is continuously provided on each of the one opposing edge of the midsole plate 11 and the reinforcing piece 14 is provided on each of the other opposing edges. ing.
[0037]
Since the folding procedure and the buffer function of the packing material 200B of this embodiment are the same as those of the packing material 200A, description thereof will be omitted.
[0038]
