Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cushioning material. That is, it relates to a cushioning material used for packing an object, for example.

[0002]

[Prior art]

 FIG. 4 is a front cross-sectional explanatory view showing one example of such a conventional cushioning material, showing a state at the beginning of packing, and FIG. 5 is a front cross-sectional explanation showing another example of the conventional cushioning material. It is a figure, (1) figure shows the state of the beginning of packing, and (2) figure shows the state with which the clearance gap was produced. As shown in these drawings, a honeycomb core 2 is used as a cushioning material 1 for packing, for example, a cushioning object A such as a machine, a product, fruits, vegetables, and various other articles. Conventionally, the honeycomb core 2 has been interposed, for example, between the outer box B and the cushioning target A with the cell axis direction 3 which is the thickness direction thereof facing the cushioning target A. When an impact load is applied from the outside, the honeycomb core 2 that is the cushioning material 1 buckles in the cell axial direction 3 that is the thickness direction thereof, so that the impact load acting as a compression load is relaxed and absorbed. , The buffer object A was protected.

[0003]

[Problems to be solved by the device]

 By the way, in such a conventional example, the following problems have been pointed out. First, the packed cushioning object A or the impact load from the outside causes the honeycomb core 2 as the cushioning material 1 to partially buckle during use, and particularly in correspondence with the shape and weight of the cushioning object A, for example, The lower honeycomb core 2 was apt to partially buckle under a local load. Then, as shown in FIG. 5 (2), a gap C is formed between the cushioning object A and the honeycomb core 2 by the amount corresponding to the space corresponding to the buckling portion 4 thus formed. Occur. Therefore, due to such a clearance C, for example, a displacement of the center of gravity is caused during transportation, the shock load from the outside afterwards is not relaxed and absorbed by the honeycomb core 2 smoothly, and so on. This is a problem because the object A is easily damaged or broken and a defect is likely to occur.

Secondly, the cushioning material 1 using the conventional honeycomb core 2 is buffered by the buckling of the honeycomb core 2 as described above when a large strong impact load is applied from the outside. It exerts 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-mentioned cushioning function, so that there is a difficulty that such impact load cannot be absorbed or absorbed. . In other words, the honeycomb core 2 has a particularly high rigidity and strength in the cell axis direction 3, which is the thickness direction thereof, but it does not buckle when a small weak impact load that does not reach its buckling strength is applied. In this case, it has been pointed out that the shock load is not relaxed and absorbed, and the shock absorbing object A receives the shock load, which easily causes damage or damage to the shock absorbing object A and causes defects. .

In view of such circumstances, the present invention has been made to solve the problems of the conventional example, and uses the honeycomb core with the direction orthogonal to the cell axis direction facing the cushioning target. By doing so, firstly, to propose a cushioning material that does not cause a gap between the cushioning object and the honeycomb core, and secondly can absorb and absorb a relatively small impact load. With the goal.

[0006]

[Means for Solving the Problems]

 The technical means of the present invention for achieving this object are as follows. That is, this cushioning material is a cushioning material that uses a honeycomb core that is a planar aggregate of hollow columnar cells, and the honeycomb core is used with the direction orthogonal to the cell axis direction facing the cushioning target. ing.

[0007]

[Action]

 Since the present invention comprises such means, it operates as follows. In this cushioning material, the honeycomb core is oriented so that the direction orthogonal to the cell axis direction is directed toward the cushioning target and receives a load in the same direction, so that there is an appropriate rigidity between the cushioning target and the outside. It has resilience and elasticity as well as strength. Therefore, firstly, when a local load is applied due to a shock-absorbing object or an impact load from the outside, the honeycomb core having the appropriate rigidity and strength, as well as the resilience and elasticity as described above, Such loads are alleviated and absorbed. In other words, in this cushioning material, the honeycomb core does not buckle as in the conventional example of this kind, and no gap is formed between the shock absorbing object and the honeycomb core.

Secondly, in this cushioning material, when an impact load is applied, the cushioning material relaxes and absorbs the honeycomb core by utilizing the appropriate rigidity / strength and resilience / elasticity. Therefore, even when a relatively small impact load is applied, it can be alleviated and absorbed.

As shown in FIG. 6, the honeycomb core 6 is composed of a planar assembly of hollow columnar cells 8 each partitioned into independent spaces by the cell walls 7. The cross-sectional shapes of the cell walls 7 and the cells 8 are as shown in the figure. In addition to regular hexagons, triangles, squares, trapezoids, and other various shapes are possible. The honeycomb core 6 is generally excellent in weight ratio strength, is lightweight, has high rigidity and strength, and is also excellent in rectifying effect, plane accuracy, heat retention, sound insulation, etc. It is known that it has a large surface area and so on. The honeycomb core 6 may be a spreading method of cutting, applying adhesive, stacking, adhering and spreading the base material sheet, or corrugating the base material sheet into corrugated sheets, and then cutting, joining, Molded by the corrugated method.

The honeycomb core 6 of the cushioning material 5 has a direction orthogonal to the cell axis direction 3 facing the cushioning object A. That is, in the case where the honeycomb core 6 is formed by, for example, the expansion method, as shown in FIG. 2A, the W direction (stacking direction, The stretching direction) is directed toward the buffer object A, or, as shown in FIG. 2B, the L direction orthogonal to the cell axis direction 3 (ribbon direction, that is, the W direction on the same plane). The direction (orthogonal direction) is directed toward the buffer object A. Even when the honeycomb core 6 formed by the corrugated method is used, the stacking direction orthogonal to the cell axis direction 3 is directed toward the buffering target A according to these, or the same plane as this stacking direction is used. The direction that is orthogonal to and is also orthogonal to the cell axis direction 3 is directed to the buffer object A. As described above, in this cushioning material 5, the honeycomb core 6 has the cell axial direction 3, which is the thickness direction thereof, oriented parallel to the cushioning target A, and the side surface orthogonal to the opening end face of the cell 8 is the cushioning target. It comes into contact with the object A. In addition, D in FIG. 2 is a striation bonding portion between the cell walls 7.

In the cushioning material 5 of the second embodiment shown in the figure, one such honeycomb core 6 is arranged below the cushioning target A. Of course, in this cushioning material 5, the honeycomb core 6 is used at various other positions and numbers, but in any case, it covers the target surface of the buffering target A to which an impact load from the outside is applied.

It should be noted that FIG. 3 shows various usage patterns of the honeycomb core 6 in the cushioning material 5. In addition, FIG. 3 (1) shows an example in which the honeycomb core 6 is used alone as it is. FIG. 3B shows an example in which the sheet material 9 is attached to the side surface of the honeycomb core 6 as a single-sided material. Further, FIG. 3 (3) shows an example in which the sheet material 9 is attached to both side surfaces of the honeycomb core 6 as both-side surface materials. The sheet material 9 has a planar shape, and cardboard sheets, polyethylene sheets, polystyrene sheets, other resin sheets, cellulose fibers, other fibers, foam materials, and various other materials are used. Then, such a sheet material 9 functions to prevent the occurrence of scratches on the cushioning target A or the like. As the honeycomb core 6, in the first embodiment shown in FIG. 1 (1), the sheet material 9 shown in FIG. 3 (2), which is a single-sided surface material, is attached. In the second embodiment shown in FIG. 1 (2), each of those shown in FIG. 3 (1) is used.

The present invention is configured as described above. Then it becomes as follows. That is, in this cushioning material 5, the honeycomb core 6 is arranged with the direction orthogonal to the cell axis direction 3 facing the cushioning target A. In other words, the honeycomb core 6 of the cushioning material 5 is directed to the cushioning object A in the W and L directions orthogonal to the cell axis direction 3 of extremely high rigidity and strength, and a load is applied in the W and L directions. It is designed to receive this, and therefore, between the object to be buffered A and the outside, it has appropriate rigidity and strength, as well as resilience and elasticity, and also exerts a spring-like function that does not buckle. The cushioning material 5 is used for packing the cushioning target A and other purposes, and has the following first and second configurations.

First, during use, the honeycomb core 6 of the cushioning material 5 is locally subjected to a load due to an impact load from the cushioning target A or from the outside, particularly in accordance with the shape and weight of the cushioning target A. The case would be: In this case, such a load is alleviated and absorbed by the honeycomb core 6 having appropriate rigidity and strength as well as resilience and elasticity, that is, the honeycomb core 6 that compresses and restores. That is, unlike the conventional example shown in FIG. 5 and the like, the method of relaxing and absorbing this by buckling is not used, and since this honeycomb core 6 does not buckle, there is no gap between the buffer target A and the honeycomb core 6. .

Secondly, and in the case of the shock absorbing material 5, when an impact load is applied, by utilizing the appropriate rigidity / strength and the resilience / elasticity of the honeycomb core 6, the cushioning function is provided. The honeycomb core 6 receives, relaxes and absorbs the impact load acting as a compressive load. Therefore, even if a relatively small impact load is applied, it can be received and absorbed and absorbed. As described above, the cushioning material 5 can not only absorb and absorb a relatively large impact load, but also can absorb and absorb a small weak impact load, and can easily cope with impact loads of various sizes. is there.
