JP2002145340A - Cardboard-made shock-absorbing member - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a cardboard-made shock-absorbing member capable of easily packaging either a column-like or an elliptical column-like item. SOLUTION: Each of side plates 2 and covering plates 3 is cooperatively arranged at each of outer edges of a pair of connected receiving plates 1, 1. Handle holes 4 are arranged at the covering plates 3, end plates 5 are extended out of the end edges of the receiving plates 1, 1 and the covering plates 3. When a user puts his hand into the handle holes 4 and falls it into an outer box B while holding the box, the inner edges of the end plates 5 are abutted to each other to cause the receiving plates 1, side plates 2 and covering plates 3 to become a hexagonal column-shape and then the packaged item G is packaged with it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material made of corrugated cardboard used for packing articles having a cylindrical or elliptical column shape.

[0002]

2. Description of the Related Art In general, when packing an article such as a column-shaped electric product, two cushioning members made of styrene foam having a concave portion on an end face are opposed to each other, and an object to be packaged is sandwiched between these cushioning members. Both ends of the article to be packed are fitted into the recesses of the respective cushioning materials, and in this state, the article to be packed is stored in an outer box together with the cushioning material.

[0003]

However, when such a cushioning material is used, it takes time and effort to insert the article to be packed into the outer box and take it out of the outer box. There is also the problem of adverse effects on the environment.
For this reason, there is a demand for a cushioning material having a small environmental load and excellent in packing workability.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a cardboard made of recyclable and easily incinerated material, in which side plates and cover plates are sequentially connected to the outer edges of a pair of connected receiving plates, respectively. And when the end plate is extended from the edge of the cover plate and the object to be packed is placed on the receiving plate and stored in the outer box, the inner edges of the end plate abut each other, and the receiving plate, the side plate and the cover plate become hexagonal cylindrical. Thus, a cushioning material for wrapping the article to be packed was provided.

[0005] Further, at the ridges of the receiving plate, the cover plate and the side plate,
When the side plate is cut and a projection is provided, the projection comes into contact with the side wall of the outer box, and a buffer space is secured on the side of the article to be packed,
It is buffered by the deformation of the projection.

Further, when the outer edge of the end plate is made to protrude from the side plate, the outer edge comes into contact with the side wall of the outer box, so that even if a large impact is applied, it is difficult to deform.

If the cover plate is provided with a handle hole, it is possible to pack the product simply by lowering it into the outer box while inserting and gripping the handle hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a cardboard cushion blank according to the present invention. In this blank, as shown in the figure, side plates 2 are respectively attached to the outer edges of a pair of connected receiving plates 1.
And the cover plate 3 are sequentially provided, and the cover plate 3 is provided with a handle hole 4.

An end plate 5 is connected to the end edges of the receiving plate 1 and the cover plate 3, and the outer edge of the end plate 5 connected to the receiving plate 1 projects from the ridge line with the side plate 2, and the end plate 5 is brought into abutment at the time of packing. Is cut diagonally.

In the ridges of the receiving plate 1, the cover plate 3, and the side plate 2, two projections 6 are provided by cutting the side plate 2 respectively.

In the cushioning material S made of such a blank, as shown in FIG. 2, the article G to be packed is placed on the receiving plate 1, and the hand is inserted into the handle hole 4 and gripped. When it is lowered, the lower end plate 5 comes into contact with the end wall 7 of the outer box B from the inner edge, and is naturally bent upward.

As shown in FIGS. 3 and 4, when the cushioning material S is lowered by its own weight and placed in the outer box B, the adjacent receiving plate 1 is restricted by the side wall 8 of the outer box B so that the angle of the adjacent receiving plate 1 is increased. None, the inner edges of the lower end plates 5 abut against each other, so that a buffer space is secured below the article to be packed G.

Next, the upper end plate 5 is bent inward,
When the inner edges are brought into contact with each other and the cover plate 3 is placed on the object to be packed G, the receiving plate 1, the side plate 2, and the cover plate 3 have a hexagonal tubular shape that wraps the object to be packed G. A buffer space is secured above.

Further, with this packing, the protrusion 6 rises from the side plate 2 and abuts on the side wall 8 of the outer box B in an inclined state, and the outer edge of the lower end plate 5 protrudes from the side plate 2 to form the outer box B. Since it comes into contact with the side wall 8, a buffer space is also secured on the side of the article to be packed G.

In this packed state, when an impact acts from the side, the tip of the projection 6 is crushed to absorb the impact, and the gap between the side plates 2 is maintained by the contact between the inner edges of the end plates 5. Thus, the article to be packed G is protected.

Furthermore, even if a large impact acts from below due to a drop or the like, the angle between the receiving plates 1 is maintained because the outer edge of the lower end plate 5 is in contact with the side wall 8 of the outer box B. hand,
The buffer space below the article to be packed G is maintained.

In the direction of the end face of the packaged object G, the end plate 5
In order to obtain the buffering property by the thickness of the package G, when the weight of the article to be packed G is large, the end plate 5 may be folded and thickened.

[0018]

As described above, the cushioning material according to the present invention has a hexagonal cylindrical shape that wraps around the object to be packaged only by placing the object to be packed and lowering it into the outer box, so that an appropriate cushioning property can be obtained. .

Further, since corrugated cardboard is used as a material, it can be collected and regenerated after use, and can be easily incinerated.
