BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material. That is, the present invention relates to a cushioning material used for, for example, packing of a buffering object.

[0002]

2. Description of the Related Art FIG. 4 shows one of such conventional cushioning materials.
It is a front sectional explanatory view showing an example, showing a state at the time of packing,
5A and 5B are front sectional explanatory views showing another example of the cushioning material of the conventional example. FIG. 5A shows a state at the beginning of packing, and FIG. 5B shows a state where a gap is formed. As shown in these drawings,
A honeycomb core 2 is used as a cushioning material 1 for packing, for example, a buffering object A such as a machine, a product, a fruit, a vegetable, and various other articles. While turning the direction 3 toward the buffer object A,
It was interposed alone, for example, between the outer box B and the buffer object A. When an impact load is applied from the outside, the honeycomb core 2 serving as the cushioning material 1 buckles, thereby absorbing and absorbing the impact load, and protecting the buffering object A.

[0003]

However, the following problems have been pointed out in such a conventional example. First
In addition, the honeycomb core 2 serving as the cushioning material 1 partially buckles during use due to a large shock load from the packaged buffering object A and the outside. The honeycomb core 2 was locally loaded and easily buckled partially. Then, as shown in FIG. 5 (2), a gap C is generated between the buffer target A and the honeycomb core 2 by an amount corresponding to the space corresponding to the buckling portion 4 thus formed. I will be. Therefore, due to such a gap C, for example, the entire center of gravity shifts during transportation, or the honeycomb core 2 does not smoothly absorb or absorb a large external impact load after the fact. For example, the buffering object A is damaged or broken due to the like, and defects are likely to occur, which has been a problem.

[0004] Second, the cushioning material 1 using the conventional honeycomb core 2 has a structure in which when a large strong impact load is applied from the outside, the buckling of the honeycomb core 2 proceeds as described above. It can exhibit its function and can absorb and absorb such an impact load to protect the buffer object A. However, when a relatively small impact load is applied from the outside, the honeycomb core 2 does not buckle and does not exhibit the above-described cushioning function, and thus there is a problem that such an impact load cannot be reduced or absorbed. That is, the honeycomb core 2 has high rigidity and strength, and does not buckle when a small weak impact load that does not reach its buckling strength is applied. In this case, the impact load is not relaxed or absorbed. A problem has been pointed out that the shock absorbing object A receives an impact load, and the shock absorbing object A is easily damaged or broken from this surface and defects are likely to occur.

The present invention has been made in view of such circumstances, and has been made in order to solve the problems of the above-described conventional example. By using a predetermined elastic material together with the honeycomb core, that is, the elastic material is used. First, the honeycomb core is partially interposed in the cells of the honeycomb core, interposed between the honeycomb cores, or interposed in the removed portion in which the honeycomb core is partially deleted. Secondly, it is an object of the present invention to propose a cushioning material which does not cause a gap between the object and the object to be buffered even if it buckles, and can relax and absorb a relatively small weak impact load.

[0006]

The technical means of the present invention for achieving this object is as follows. This cushioning material
A cushioning material using a honeycomb core, which is a planar assembly of hollow columnar cells, wherein the honeycomb core is oriented in a cell axis direction toward an object to be buffered, and is restored in the cell axis direction together with the honeycomb core. An elastic material having properties is used. In the cushioning material according to the first aspect, the elastic material is interposed in the cells of the honeycomb core. In the cushioning material of the second aspect, the elastic material is interposed between the honeycomb cores. In the cushioning material according to the third aspect, the elastic material is interposed in a removed portion obtained by partially removing the honeycomb core.

[0007]

The present invention is constituted by such means, and operates as follows. In this cushioning material, the honeycomb core is arranged with the cell axis direction facing the buffer object, and a predetermined elastic material having resilience in the cell axis direction is used together. That is, in the first aspect, the elastic material is interposed in the cells of the honeycomb core, in the second aspect, the elastic material is interposed between the honeycomb cores, and in the third aspect, the elastic material is interposed in a portion where the honeycomb core is partially deleted. Is equipped. Therefore, first, in the cushioning material according to claim 1, claim 2 or claim 3, when the honeycomb core receives a local load and partially buckles due to a large impact load from a buffering object or the outside. A gap is generated between the buffer object and the honeycomb core corresponding to the buckling portion, and such a gap is supplemented with the elastic material at the same time as the generation. That is, in this gap, the elastic material
Since it is immediately embedded and interposed by the repulsive force, the cushioning material according to any one of the first, second, and third aspects does not have any gap between the cushioning material and the cushioning object.

[0008] Second, and claim 1, claim 2,
In the cushioning material according to the third aspect, when a large impact load is applied, the honeycomb core buckles in this manner, and the impact load is reduced and absorbed. On the other hand, when a small weak impact load is applied, the honeycomb core does not buckle, but the elastic material is compressed to reduce or absorb the impact load. in this way,
According to the cushioning material of the first, second and third aspects, not only a large impact load can be relaxed and absorbed, but also a small weak impact load can be relaxed and absorbed.

Third, in the first aspect, the elastic material is interposed in the cells of the honeycomb core, and in the second aspect, the elastic material is interposed between the honeycomb cores. Therefore, these claims 1
Thirdly, in addition to the above, the configuration of the cushioning material according to claim 2 is simple and easy.

Fourthly, in the third aspect, the elastic material is interposed in the removed portion of the honeycomb core. Fourthly, in addition to the above, the cushioning material according to claim 3 is provided with a honeycomb core that receives a large strong impact load and an elastic material that receives a small weak impact load, respectively, in an appropriate position. Can be appropriately received, and the point described in the second can be realized more smoothly.
