Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is for packaging for buffering the influence of an external force on a packing object that is arranged in the packing box and supports the packing object when the packing object is accommodated in the packing box and packed. The present invention relates to a cushioning material and a packing box.
[0002]
[Prior art]
FIG. 9 shows an example of a conventionally used packaging box.
The packaging box 1000 can accommodate and package the television receiver 1003 as a packaging object, for example. The television receiver 1003 is accommodated in the packaging box 1000 after being put in the protective bag 1005.
The four corners 1007 at the bottom of the television receiver 1003 are placed on the inner surface of the bottom surface 1010 of the packaging box 1000 using cushioning materials 1009, respectively.
The buffer material 1009 is not a plastic foam material such as polystyrene foam, but is made by pulp molding a paper sheet-like member.
[0003]
Plastic foam materials have been used for packaging or packaging of packaging objects related to home appliances. The reason why the plastic foam material was used is that it has a good shock-absorbing property and is less deteriorated due to environmental conditions, and is excellent in mass production and high-speed packing workability by an automatic packing machine.
However, in recent years, the number of used plastic foam materials that are thrown away as trash has increased rapidly, and so buffer materials made from pulp-molded paper have been used to protect the global environment. .
[0004]
[Problems to be solved by the invention]
However, for example, when a heavy object such as the television receiver 1003 is accommodated in the packaging box 1000 and packed and transported, the material strength of the cushioning material 1009 made by pulp molding is limited. In order to increase the strength of the cushioning material 1009, the thickness of the cushioning material 1009 is significantly increased than usual, or a corrugated cardboard sheet 1010 for reinforcement is separately prepared, and the corrugated cardboard sheet 1010 is attached to the packaging box 1000. It is necessary to arrange on the inner surface of the bottom surface 1010 to reinforce strength.
Particularly in the case of the television receiver 1003, for example, such a reinforcing treatment is required when the screen size is larger than a large size of 25 inches.
[0005]
As described above, in order to compensate for the lack of strength when the four corners 1014 of the packaging box 1000 are dropped on the floor surface or the like while the packaging box 1000 in which the television receiver 1003 is packed is being conveyed, As described above, the thickness of the cushioning material 1009 must be increased or the cardboard sheet 1010 must be prepared separately. Therefore, there is a problem that the cost for preparing the packaging box 1000 is unavoidable.
Accordingly, the present invention solves the above-described problems, and provides a packing cushioning material and a packing box that can easily reinforce the strength of the packing cushioning material by reinforcing the strength of only the necessary portion of the packing cushioning material.

The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.
[0017]
FIG. 1 shows a preferred embodiment of a packaging box provided with the cushioning material for packaging of the present invention.
The packaging box 10 shown in FIG. 1 is also called a packaging box, and the packing cushioning material is also called a packaging cushioning material.
The packing box 10 includes, for example, a rectangular parallelepiped box 13, four packing cushioning materials 20, 21, 22, 23 on the lower side, two reinforcing members 30, 31, and three cushioning materials 40, 41 on the upper side. 42.
[0018]
The box 13 of the packaging box 10 includes a bottom surface portion 50, four side surface portions 51, 52, 53, 54 and four upper flaps 60, 61, 62, 63.
The upper flaps 60 to 63 can close the upper opening 70 so as to be openable and closable.
The packaging box 10 is made of paper such as corrugated paper or plate-like plastic.
As an example of the packing object, the television receiver 100 is shown in the example of FIG. The television receiver 100 is, for example, a 25-inch television receiver and is relatively heavy. The television receiver 100 is accommodated in a protective transparent bag 101.
[0019]
The lower cushioning material 20 that is the first cushioning material shown in FIG. 1 supports the lower left front corner 110 of the television receiver 100. Similarly , the packing cushioning material 21 as the first cushioning material supports the corner portion 111 in the lower right front of the television receiver 100. The packing cushioning material 22 supports the lower left corner 112 of the television receiver 100. The packing cushioning material 23 supports the lower right rear corner 113 of the television receiver 100.
The packing cushioning materials 20, 21, 22, and 23 are placed on the inner surface 50 </ b> A that is the inner wall surface of the bottom surface portion 50 of the box 13. That is, the packing cushioning material 20 is set on the inner surface of the corner portion 120 that is the bottom corner portion in the lower left front of the box 13, and the packing cushioning material 21 is the corner that is the bottom corner portion in the lower right front of the box body 13. The inner surface of the part 121 is set. Further, the packing cushioning material 22 is set on the inner surface of the lower left corner 122 of the box 13, and the packing cushion 23 is set on the inner surface of the lower right corner 123 of the box 13.
[0020]
The upper cushioning material 40 is set at the upper corner 130 of the television receiver 100, the cushioning material 41 is set at the upper right corner 131 of the television receiver 100, and the cushioning material 42 is set at the television receiver 100.

Thus, the television receiver 100 is accommodated in the packaging box 10 using the upper and lower cushioning materials, so that each cushioning material cushions the influence of external force on the television receiver 100. It can be done or relaxed.
[0021]
As shown in FIG. 1, the characteristic is that reinforcing members 30 and 31, which are second cushioning materials, overlap each other on the cushioning material 20 in the lower left front and the packing cushion 21 in the lower right front. It is attached.
Thus, the reinforcing members 30 and 31 are attached to the packing cushioning materials 20 and 21, respectively, and the reinforcing member is not attached to the rear packing cushioning materials 22 and 23. This is because the corners 110 and 111, which are lower corners on the lower side on the front side of the television receiver 100 , are more likely to be damaged when dropped on the floor surface or the like than the rear corners 112 and 113. That is, in the illustrated television receiver 100, the rear corners 112 and 113 have a slightly narrowed outer shape as compared with the front corners 110 and 111. In this case, the reinforcing members 30 and 31 are mounted in consideration of this point.
Therefore, reinforcing members 30 and 31 are attached to the cushioning materials 20 and 21 for packing in order to reinforce the strength of the cushioning materials 20 and 21, respectively.

In FIG. 2, the reinforcing member 31 reinforces the packing cushioning material 21 in a strong manner by arranging the reinforcing member 31 so as to be detachable so as to overlap the packing cushioning material 21 in the direction of the arrow. it can. Since such a structure is the same also in the assembly of the cushioning material 20 for packing and the reinforcing member 30 shown in FIG. 1, the description will be used.
[0024]
Both the packing cushioning material 21 and the reinforcing member 31 in FIG. 2 are formed by pulp molding a paper sheet. That is, the cushioning material 21 for packing and the reinforcing member 31 are made by pulp molding from a paper material such as cardboard instead of a plastic foam material such as polystyrene foam. Such a pulp-molded packing cushioning material and reinforcing member can be said to be a material with little waste pollution because the waste volume is not bulky and the amount of collected waste can be reduced easily and can be recycled.
[0025]
The cushioning material 21 for packing shown in FIG. 2 has a bottom portion 21A and side portions 21B and 21C, which are first bottom surface portions .

The second surface portion 141 and the third surface portion 142 are formed upright with respect to the first surface portion 140.
When the reinforcing member 31 is overlaid on the cushioning material 21, the upper surface of the first surface portion 140 is substantially in close contact with the lower surface side of the bottom portion 21A. The inner surface of the second surface portion 141 is in close contact with the outer surface of the side portion 21B. The inner surface of the third surface portion 142 is in close contact with the outer surface of the side portion 21C.
By assembling the reinforcing member 31 so as to overlap the packing cushioning material 21, the first surface portion 140 to the third surface portion 142 described above are in close contact with the bottom portion 21A and the side portions 21B and 21C of the packing cushioning material 21, respectively. And overlap. At this time, the fitting portion 143 can be positioned in the vertical direction in the convex portion 21E, so that the reinforcing member 31 and the packing cushioning material 21 can be positioned. The displacement of the material 21 can be prevented.
[0027]
FIG. 3 shows a cross-section of an example in which the reinforcing member 31 and the packing cushioning material 21 are assembled together.
