[0003]

However, in the above-mentioned cushioning material, since the product to be stored is used so as to abut the folded plate 57 and each side plate 55, the cushioning box is vibrated during transportation. When the body 53 is distorted, the locking piece 5
8 and the hooking portion 59 are likely to be disengaged, the shape of the buffer box 53 may be broken, and sufficient buffering properties may not be obtained.

[0004] Therefore, an object of the present invention is to provide a cushioning material whose shape is firmly held and stable cushioning properties can be obtained.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a pair of frame plates facing each other at a predetermined interval, and has projections provided at both ends of front edges thereof, and rear ends of both frame plates. The edges are covered with a back plate, and the leading edges of the opposing projections of both frame plates are connected via a connection plate, and the edges between the projections of both frame plates are connected via a step member. The step member, the step plate, the folding plate and the inner folding plate are sequentially connected, the step plate is erected, and the folding plate and the inner folding plate are bent rearward and overlapped, and the folding plate and the inner folding plate are formed. The connecting portion of the plate was brought into contact with the back plate.

[0006] In this cushioning material, the continuous portion of the folding plate and the inner folding plate abuts against the back plate, so that when a force in the front-rear direction is applied, the backward swinging of the step plate is prevented, and the step is prevented. The member reliably receives the article to be packed without being deformed.

[0007] On the other hand, when a force in the width direction is applied, the protruding pieces that are a part of each frame plate and the connecting plate connected to the protruding pieces absorb the shock acting on the packaged object.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The development substrate of the cushioning material according to the present invention is made of a corrugated cardboard sheet and has a structure as shown in FIG. As shown in the drawing, protrusions 1a and 2a are provided at both ends of one end of the first frame plate 1 and the second frame plate 2, respectively.
Are connected via

The first frame plate 1 sandwiched between the protruding pieces 1a, 1a
And the edge of the second frame plate 2 sandwiched between the projecting pieces 2a, 2a are connected via a step member 4. This step member 4
In the figure, a first step plate 5, a folding plate 6, an inner folding plate 7, and a second step plate 8 are sequentially provided from the first frame plate 1 side to the second frame plate 2 side. In the first step board 5 and the second step board 8, through holes 5a and 8a are formed at two places, respectively.

An outer back plate 9 and an inner back plate 10 are connected to the other end edges of the first frame plate 1 and the second frame plate 2, respectively. A piece 11 has an insertion hole 12 formed in a continuous portion between the second frame plate 2 and the inner back plate 10.
A first side plate 13 and a first flap 14 are sequentially provided from both side edges of the first frame plate 1, and a second side plate 15 and a second flap 16 are sequentially provided from both side edges of the second frame plate 2. Notches 10a are formed at both ends of the inner back plate 10 toward the inside, and
A projecting piece 16a is provided on the tip edge of the flap 16 toward the side.

When assembling the development board, FIG.
As shown in FIG. 5, the connecting plate 3 is raised with respect to the second frame plate 2, and the first frame plate 1 is bent backward, the first step plate 5 is bent downward, and the second step plate 8 is bent upward. Then, the folding plate 6 and the inner folding plate 7 are bent backward, and the folding plate 6 and the inner folding plate 7 are overlapped.

Then, the first side plate 13 is bent downward, the second side plate 15 is bent upward, the first flap 14 and the second flap 16 are folded inward, and the two flaps 14 and 16 are overlapped. 3 is bent upward, the outer back plate 9 is bent downward, the outer back plate 9 is overlapped on the outer surface of the inner back plate 10, and the insertion piece 11 is inserted into the insertion hole 12 to engage them. Is formed.

In this cushioning material, as shown in FIG. 4, a continuous portion of the folding plate 6 and the inner folding plate 7 abuts on the inner back plate 10, and the protruding piece 16a is inserted into the notch 10a.

Now, for example, in order to pack home electric appliances using the cushioning material as described above, the surface of the home electric appliances housed in the case is made to conform to the step member 4 and the projecting pieces 1a,
2a and the inner surface of the connecting plate 3.

[0015] With this packing, when an external force acts on the case in the front-rear direction on the cushioning material during transportation or the like,
The rearward swing of the two step plates 5 and 8 is prevented by the contact of the continuous portion of the folding plate 6 and the inner folding plate 7 with the inner back plate 10, and the step member 4 is formed.
Can reliably receive home appliances without deformation. Also, the through holes 5a, 8a allow a slight bending of each of the step plates 5, 8, and the impact acting on the home electric appliance is effectively reduced.

On the other hand, when an external force in the width direction acts on the cushioning material on the case, the projecting pieces 1a and 2a, which are portions of the first frame plate 1 and the second frame plate 2, are connected to these. The connecting plate 3 absorbs an impact acting on the home electric appliance.

In addition, the vertical load acting on the cushioning material compresses the first side plate 13 and the second side plate 15 up and down, but since the protruding piece 16a is in contact with the edge of the cut portion 10a, The load is dispersed to the inner back plate 10, and deformation of the cushioning material is suppressed.

The direction of the corrugation of the corrugated cardboard is usually set so as to coincide with the connecting direction of the frame plates 1 and 2, but by setting the direction obliquely with respect to the connecting direction of the frame plates 1 and 2, Sufficient cushioning properties can be obtained in two directions, the direction and the width direction.

The first side plate 13, the first flap 14, the second side plate 15, and the second flap 16 may be omitted.

The space between the rear edges of the frame plates 1 and 2 is, for example,
Only one of the outer back plate 9 or the inner back plate 10 is provided,
Instead of engaging with the insertion hole 12, the connection may be made by a configuration other than the above, such as by retaining the shape with an adhesive tape.

Further, as shown in FIGS. 5 and 6, the shape of the step member 4 is made smaller, for example, by making the vertical dimension of the second step plate 8 smaller than that of the first step plate 5, as shown in FIGS. It may be changed appropriately.

[0022]

According to the present invention, as described above, since the continuous portion of the folding plate and the inner folding plate is in contact with the back plate, the rearward swing of the step plate against the force in the front-rear direction. Is prevented, and the step member reliably receives the article to be packed without being deformed.

Further, with respect to the force in the width direction, the projecting piece which is a part of each frame plate and the connecting plate connected to the projecting piece absorb an impact acting on the article to be packed.

As described above, since a stable cushioning property can be obtained even when formed of corrugated cardboard, there is no need to use a cushioning material made of styrofoam, so that the packaging cost can be reduced and the discard is easily made after use. be able to.
