【Example】

 The cushioning body according to this embodiment is constructed by a main body made of corrugated cardboard and auxiliary plates made of corrugated cardboard attached to both sides of the main body.

FIG. 1 shows a state in which a main body 10 made of corrugated cardboard is unfolded, and a pair of folding lines 11 that are parallel to each other are formed in the center of the base paper 10 in the width direction. A fold line 12 composed of a double line is formed outside the fold line 11. The portion between the bending lines 11 at the center constitutes a horizontal plate 13. Further, the region formed between the bending line 11 and the bending line 12 constitutes the upright plate 14. Further, the outer side of the double folding line 12 constitutes a side plate 15.

Slit-shaped openings 18 extending in the width direction of the base paper 10 are formed at both ends in the length direction of the base paper 10 so as to cross the four folding lines 11 and 12. . Further, slit-shaped notches 19 are formed on the upper edges of the side plates 15, respectively. Further, perforations 20 are formed at both ends in the length direction of the base paper 10 and on the tip side of the slit-shaped opening 18. The four corners of the base paper 10 are each cut out to form a hypotenuse 21.

Next, the auxiliary plate 25 combined with the main body 10 made of such a base paper will be explained. As shown in FIG. 2, the corrugated cardboard base paper 25 constituting the auxiliary plate has a substantially rectangular parallelepiped shape, and its width direction. Five fold lines 26, 27, 28, 29, 30 are formed in parallel with each other so as to extend in the direction. Further, a U-shaped cut 31 is formed at one end of the auxiliary plate 25. A shallow U-shaped cut 32 is formed at the opposite end, and slit-shaped cuts 33 are formed at the roots on both sides of the cut 32, respectively.

Next, the operation of assembling the buffer body by the main body 10 and the auxiliary plate 25 as described above will be described. When assembling the main body 10 made of corrugated cardboard as shown in FIG. 3, first, the upright plates 14 on both sides of the horizontal plate 13 are bent downward by the pair of bending lines 11 of the cardboard 10. After that, as shown in FIG. 4, the tip of the upright plate 14 is bent upward by 180 ° by the bending line 12 formed of the double line on the outer side so that the side plate 15 is superposed on the outer side of the upright plate 14. To As a result, the body portion 10 is assembled.

Next, the operation of combining the auxiliary plate 25 with the main body 10 will be described. The U-shaped cut 32 on the other end side of the auxiliary plate 25 and the slit-shaped cuts 33 on both sides thereof are combined with the slit-shaped opening 18 of the main body portion 10 from below. When the main body 10 is assembled by bending the corrugated cardboard base paper 10 as described above, the slit-shaped opening 18 is opened downward, and the slit-shaped opening 18 is cut into the auxiliary plate 25 in a U-shape from below. 32 and the slit-shaped notch 33 are engaged with each other.

After that, the bending lines 30 of the auxiliary plates 25 on both sides are bent at right angles as shown in FIG. After that, the bending line 29 is further bent at a right angle. Further, while bending the folding lines 28 and 27 by about 45 °, a U-shaped cut 31 on the upper end side of the auxiliary plate 25 is formed in the slit-shaped cut 19 which is opened at the upper end of the main body 10 as shown in FIG. Engage in. Since the slit-shaped notch 19 of the main body 10 is opened upward as shown in FIG. 4, the U-shaped notch 31 at the upper end of the auxiliary plate 25 is engaged with such notch 19. As a result, the auxiliary plate 25 covers both ends of the main body 10, and both ends of the auxiliary plate 25 are locked by the slits 19 and 18 which are open to the upper portion and the lower portion of the main body 10, respectively.

In the packaging box such as a cardboard box for storing the article, the shock absorber thus assembled is interposed between the packaging box and the article and absorbs an impact from the outside. Therefore, the shock absorber from the outside is absorbed by the cushioning body in which the main body 10 and the pair of auxiliary plates 25 are combined, so that the articles in the packaging box can be protected.

FIG. 7 and FIG. 8 show an example used as a cushioning body when packaging the electronic device 40. Here, a pair of cushioning bodies assembled as shown in FIG. Both ends of the electronic device 40 are supported by the pair of buffers. The shock absorber is horizontally arranged so that the recesses 39 between the pair of upright plates 14 face each other, and the recesses 39 receive both ends of the electronic device 40.

In such a state, as shown in FIG. 8, a pair of left and right shock absorbers are housed in the packaging box 45, and the electronic devices 40 are supported in a floating state in the packaging box 45 by these cushioning members. It has become so. The upper opening of the packaging box 45 is closed by a cover plate 46.

Since such a cushioning body can be assembled by combining the main body 10 made of corrugated cardboard and the auxiliary plate 25 also made of corrugated board as described above, such a cushioning body is used. When the body is supplied, it can be supplied in the expanded state as shown in FIGS. 1 and 2. Therefore, no space is required when supplying. Moreover, since it is only necessary to assemble it before use, it becomes possible to store it in a flatly expanded state even when storing it.

Further, since such a cushioning body is constructed by combining the corrugated board base paper 10 shown in FIG. 1 and the corrugated board base paper 25 shown in FIG. 2, a punching die for punching the corrugated board base paper into a predetermined shape. The mold for molding is not necessary. Since the punching die is made by incorporating a blade into a wooden plate, not only is it easy to manufacture, but it can be adapted to any shape. In addition, it is possible to deal with buffers in small lots, and since the cost of the punching die is not high, the cost of buffers does not increase even in small lots.

Further, since such a buffer body is constructed by the main body 10 made of corrugated cardboard and the auxiliary plate 25 made of corrugated cardboard, even if it is incinerated and discarded after use, it does not emit harmful gas. It does not cause air pollution and does not cause air pollution. Also, it does not generate high temperature during incineration and damage the furnace. Furthermore, such a cushioning body made of corrugated fiberboard can be recycled as pulp and recycled.
