意味である。The formation area (formation position) on the outer surface of each of the wall portions 18 to 26 of the leg portion 28 will be described with reference to the wall portions 22 and 26 as an example. Generally, as shown in FIG. Is partially formed in the wall portions 22 and 2

To the portion of the wall portion 22 located directly above the portion (the portion of the leg portion 28 and the wall portion 22 sandwiched between the inner surface 22b of the wall portion 22 and the lower end of the leg portion 28). The attached portion C) is mainly elastically deformed. The meaning of "mainly" means that the cushioning material 10 is integrally formed of a foam material, so that the amount of elastic deformation decreases as the distance from the portion to which the load F is applied decreases, but the portion near the elastically deformable portion also completely elastically deforms. It does not mean that it does not mean that it is elastically deformed.

る。However, unlike the above-mentioned conventional cushioning material 10, the load F from the object 12 is not directly applied to the entire leg 28, but only a part thereof, that is, the formation of the leg 28. In the configuration where the load F is directly applied only to the portion included in the formation region B of the inner surface 22b of the wall portion 22 on the outer surface 22a of the wall portion 22 in the region A, the leg 28 to which the load F is not directly applied is formed. And a part of the wall 22 on which the leg 28 is formed and the wall 2 directly above it.
The amount of elastic deformation (specifically, the amount of sinking from the state before the fall) of the wall portion 26 (portion D hatched with a dotted line) intersecting with 2 mainly depends on the portion (portion C) that elastically deforms. The amount of elastic deformation is smaller than the amount of elastic deformation, and a difference occurs between the amounts of elastic deformation.

まうという課題もある。Thus, the inner surface 26b of the vertical wall 26
Since the wall portion 22 to which the load F is applied moves relatively downward, a shearing force is applied to the corner E at the intersection of the inner surface 22b of the wall portion 22 and the inner surface 26b of the vertical wall portion 26 in contact therewith. When a shear force is generated, a crack is generated at the corner E. When a crack occurs, the cushioning capacity of the cushioning material 10 decreases, and the
2 cannot be protected. This is because even if the other walls 18, 20, 24, 26 fall down and fall, like the other wall 26 shown in FIG. A similar problem arises when a part of the formation region A is configured to deviate from the formation region B of the inner surface 26b of the wall 26 on the outer surface 26a of the wall 26. When the cushioning material 10 is transported or stored, for example, the cushioning materials 10 formed in a cup shape are connected to each other by the legs 28 of one cushioning material 10 and the other cushioning material 10.
There is also a problem that it cannot be accommodated in the inside and stacked, and becomes bulky.

に位置していることを特徴とする。The present invention has the following arrangement to achieve the above object. That is, the cushioning material according to the present invention is mounted on the corners so as to surround at least one corner of the object to be housed in the box, and is provided along each outer surface of the object forming the corner. In the cushioning material in which the outer surface of each extending wall portion is formed with a leg whose tip is in contact with the inner surface of the box, the formation region of the leg on the outer surface of the wall is formed on the outer surface of the wall. Is located within the formation region of the inner surface of the wall portion.

力が発生せず、角部にクラックが発生しにくくなる。According to this, when the box body is dropped on a floor or the like with the object to be housed inside, the object to be housed covers the entire leg formed on the wall portion where the object and the inner surface are in direct contact. This leg is elastically deformed as a whole. Therefore, the entire wall on which the leg is formed sinks with the elastic deformation of the leg. Since the entire wall sinks, the vertical wall intersecting the wall moves together with the wall on which the leg is formed. As a result, no shearing force is generated at the corner formed by the intersection of the inner surface of the wall directly contacting the object and the inner surface of the vertical wall that intersects the wall, and no Cracks are less likely to occur.

ある。Two legs 28 are formed apart from each other on the outer surface 22a of the third wall 22. The formation position (formation area) A of the two leg portions 28 on the outer surface 22a of the third wall portion 22 is from the front side of the outer surface 22a of the third wall portion 22, as shown in FIGS. A region B (referred to as a region where the inner surface of the wall is formed on the outer surface of the wall) surrounded by the outer edge of the inner surface 22b that appears on the outer surface 22a of the third wall 22 when the third wall 22 is seen through. include. In FIG. 2, the formation area B is indicated by solid oblique lines. In addition,
In other words, the region B can be said to be a region surrounded by the outer edge of the inner surface 22b of the third wall portion 22 projected on the front side of the outer surface 22a of the third wall portion 22.

The case of the third wall portion 22 will be described as an example, but the same applies to the other wall portions 18, 20, 24, and 26. When the object 12 falls from the third wall portion 22 in a state of being housed in the box 14 and collides with a floor or the like, the object 12 is moved downward from the object 12 in the same manner as described in the conventional example. Is applied to the legs 28 that contact the inner surface of the box 14.
And a part of the third wall portion 22 located directly above the leg portion 28, and these are mainly elastically deformed. The portion of the cushioning material 30 that is mainly elastically deformed is indicated by oblique lines in FIG. Particularly, the elastic deformation of the narrow leg 28 is large.

ことはない。Unlike the conventional example, each leg 28 formed on the third wall 22 is completely located within the formation area B of the inner surface 22b of the third wall 22 to which the load F is applied from the object 12. Therefore, even if the leg 28 and a part of the third wall 22 located directly above the leg 28 are elastically deformed by the load F and sink downward, the movement of the third wall 22 is prevented. Accordingly, the fourth wall portion 24, the fifth wall portion 26, and the first wall portion 18 that intersect with the third wall portion 22 also move downward. Therefore,
Inner surface 22b of third wall portion 22 and inner surface 26b of fifth wall portion 26
A corner E 8 formed at the intersection with the inner wall 22, a corner E 7 formed at the intersection of the inner surface 22 b of the third wall 22 and the inner surface 24 b of the fourth wall 24, and the inner surface of the third wall 22. 22b and the corner portion E 2 which is formed at the intersection between the inner surface 18b of the first wall portion 18, no shear forces as in the prior art. Therefore,
Even if the box 14 containing the object 12 falls,
Since the corners E 2 , E 7 , and E 8 of the cushioning member 30 are not cracked, the cushioning action of the cushioning member 30 is not extremely reduced.

と考えられる。As is clear from FIG. 4, the cushioning material (described as "invention" in FIG. 4) 30 according to the present invention is a conventional cushioning material (described as "conventional product" in FIG. 4) 10 In comparison with the above, even if the object 12 is repeatedly dropped, the acceleration applied to the object 12 does not increase sharply. This is because each time the conventional cushioning material 10 falls, the corner formed between the inner surface of the wall surface to which the load from the object 12 is applied at the time of falling and the inner surface of the wall surface intersecting this wall surface It is considered that the initial buffering performance is maintained because no cracks are generated. Therefore,
Since the buffering capacity of the cushioning material 10 does not decrease even if the cushioning material 10 is repeatedly dropped as described above, for example, the recycling of the cushioning material 10 used for packing home appliances and electronic devices, which has recently become a problem, is collected and reused. It is also possible,
It is thought that it can be alleviated to be disposed of as garbage and become a social problem.

共に、コストの削減も可能となるという効果もある。According to the cushioning material of the present invention, when the box is dropped onto a floor or the like with the object to be housed inside, the box is formed on the wall where the object and the inner surface are in direct contact. Since the load of the object is applied to the entire leg, the leg is entirely elastically deformed. Therefore, the entire wall on which the leg is formed sinks with the elastic deformation of the leg. Since the entire wall portion sinks in this way, the vertical wall portion intersecting with the wall portion moves together with the wall portion on which the leg portion is formed. As a result, no shearing force is generated at the corner formed by the intersection of the inner surface of the wall directly contacting the object and the inner surface of the vertical wall that intersects the wall, and no Cracks are less likely to occur. Therefore, it is possible to prevent the shock absorbing capacity of the shock absorbing material from being extremely deteriorated each time it is dropped, and it is possible to protect the stored object for a long time. In addition, since the buffering capacity of the cushioning material is unlikely to decrease even if it falls, it is possible to collect and reuse the cushioning material, thereby making effective use of resources by recycling and reducing costs. There is also an effect that becomes.
