Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a corrugated cardboard cushioning material used for packaging home appliances and the like.
[0002]
[Prior art]
Conventionally, as a corrugated cardboard cushioning material, as shown in FIG. 6, a side plate 51 connected to each side of the periphery of the bottom plate 50 is erected, and a top plate 52 and an outer surface plate 53 that are sequentially connected to the upper edge of the side plate 51 are folded back. In order to protect the article, a buffer space is secured around the article placed in the outer box and placed on the bottom plate 51.
[0003]
[Problems to be solved by the invention]
However, since the cushioning material as described above is regulated and retained by the outer box, there is a problem that it cannot be made and the workability at the time of packing is poor.
[0004]
In addition, when a large external force is applied, the side plate may be deformed so as to fall outward, and sufficient buffering properties may not be obtained.
[0005]
Accordingly, the present invention is to provide a corrugated cardboard cushioning material that is stably retained in an assembled state and has excellent cushioning properties.
[0006]
[Means for Solving the Problems]
To solve the above problems, the present invention is to erect the side plate which is provided continuously to the bottom plate, of the adjacent side plate, provided an insertion hole which is bent at an end of one side plate, the difference in the edge of the other side plate write unit projecting the, this insertion portion, the rocking piece faces downward when the side plate of the upstanding consecutively provided, the insertion portion insertion hole, insert while bending the swinging piece, the swing piece Thus, the insertion portion is prevented from coming out of the insertion hole by the return, and the standing state of the side plate with respect to the bottom plate is maintained, so that the assembled shape is stabilized.
[0007]
Further, both sides of the outer plate are cut obliquely to reduce the amount of material used, and the step is inclined 45 ° to obtain uniform strength in each direction.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0009]
As shown in FIG. 1, in this cardboard cushion blank, side plates 2 are connected to both side edges of the bottom plate 1, side plates 3 are connected to both end edges, and a top plate 4 and an outer surface plate 5 are sequentially connected to the side plates 2 and 3. It is connected to the other side.
[0010]
Bent insertion holes 6 are provided at both ends of the side plate 2, and the insertion holes 6 extend to the top plate 4. Insertion portions 7 project from both end edges of the side plate 3, and swing pieces 8 that face downward when the side plate 3 stands are connected to the insertion portion 7. At the base ends of the side plates 2 and 3, leg pieces 9 project from the bottom plate 1.
[0011]
Further, the top plate 4 is divided by a plurality of cuts, and the ridgelines of the top plate 4 and the side plates 2 and 3 and the outer plate 5 between them are alternately shifted with the cuts in between.
[0012]
Then, both side portions of the outer surface plate 5 are cut obliquely, and the steps of the blank are inclined 45 °.
[0013]
In order to assemble this blank as shown in FIG. 2, the side plates 2 and 3 are erected from the bottom plate 1, and the top plate 4 and the outer surface plate 5 are folded back.
[0014]
At this time, as shown in FIGS. 3 and 4, when the insertion portion 7 is inserted into the insertion hole 6 while the top plates 4 at both ends are overlapped, the insertion portion 7 is inserted due to the return of the swing piece 8. The side plate 2 is prevented from coming off from the hole 6 and the standing state of the side plate 2 with respect to the bottom plate 1 is maintained.
[0015]
In the above assembly process, when inserting the insertion portion 7 into the insertion hole 6, the swing piece 8 may be bent by hand, but if the tip corner of the swing piece 8 is rounded, The portion comes into contact with the bent edge of the insertion hole 6 and the swing piece 8 is bent naturally.
[0016]
Since the cushioning material 10 assembled in this way is stable in a shape as shown in FIG. 2, it can also be prepared, and can be easily inserted into the outer box 11 as shown in FIG. 5.
[0017]
Further, in this assembled state, the top plate 4 is alternately inclined, and the space between the side plates 2 and 3 and the outer surface plate 5 is reliably maintained, so that a buffer space is secured around the article placed on the upper surface of the bottom plate 1. Is done.
[0018]
Furthermore, since the leg piece 9 protrudes downward and the bottom plate 1 is floated and supported by the leg piece 9 and the outer surface plate 5, a buffer space is also secured below the article.
[0019]
Further, when the flap 12 of the outer box 11 is folded back and the ridges are alternately inclined, the distance between the inner lid 13 and the upper lid 14 is maintained, and a buffer space is secured above the article.
[0020]
In addition, since this cushioning material has a blank shown in FIG. 1, both sides of the outer surface plate 5 are cut obliquely and the step is inclined by 45 °, so that not only uniform strength in each direction can be obtained, but also cardboard By arranging the cushion blanks on the sheet so that the hypotenuses are in contact with each other, the material can be efficiently taken and the amount of the material used can be suppressed.
[0021]
【The invention's effect】
As described above, the cushioning material made of corrugated cardboard according to the present invention inserts the other insertion portion into one insertion hole of the adjacent side plate and prevents it from coming off by the return of the swinging piece. Since it has been maintained, the shape can be stably maintained in the assembled state, can be kept, and the efficiency of the packing operation can be improved.
[0022]
Furthermore, since both sides of the outer plate are cut obliquely and the step is inclined by 45 °, uniform strength in each direction can be obtained, and the amount of material used can be suppressed.
