These are measured values in the Y-axis direction, CH2: Z-axis direction, and CH3: X-axis direction. Table 1 shows the form of the package used in the drop test. FIG. 6 shows the locations of the drop in the drop test. In addition, one surface represents an upper surface and three surfaces represent a lower surface.

う。As shown by the above test results, the residual impact of 40 to 70 G was measured in each of the drop tests. This is because the conventional gas-trapping form of the cushioning material does not have elasticity in the gas-trapping bag, so when a large impact (for example, dropping during transportation) is applied, the impact force cannot be sufficiently absorbed, It is probable that a strong residual impact was transmitted to the items contained. As a result, an inconvenience of damaging the article due to the force that could not be buffered occurred. In addition, the performance of an electronic component or the like changes even if the impact is small.

It is intended to provide a cushioning material capable of preventing breakage of the material.

Cushioning material 2 0 encapsulating care bodies, gas is sealed in a bag in the state of FIG. 1 (a). As shown in FIG. 1 (b), when an external force F is applied in the direction of the arrow, a weak material portion having a weak material strength is obtained.
25 breaks first. When the weak material portion 25 breaks, the air in the cushioning material 20 escapes outside and absorbs the external force F. The cushioning material 20 is a flat type, and when air completely escapes, the upper surface

材２０に落下加速度Ｆａが加えられる。Here, an example of use of the cushioning member 20 will be described with reference to FIGS. The article 60 is accommodated in the cardboard 50, and the gap between the article 60 and the cardboard 50 is filled with the cushioning material 20 and packed. In this packed state, it is dropped on the ground G. When the cardboard 50 falls and collides with the ground G, a drop acceleration Fa is applied to the cushioning material 20 between the ground G and the article 60 due to the inertial force of the article 60.

撃力が伝わってしまった。Normally, when the material of the cushioning material does not have enough elasticity to sufficiently cushion the impact, the cushioning force is limited to the range in which the sealed gas is compressed within the range of the tensile strength of the material and the cushioning force of the cardboard itself. The fall acceleration Fa can be absorbed up to the range. However, when the drop acceleration was higher than that, the shock absorbing material could not absorb the drop impact, and a strong residual impact force was transmitted to the article.

た紙材となる。The shock absorbing material 20 of the present invention absorbs shock as follows. The cushioning material 20 is interposed between the cardboard 50 and the article 60 as an air bag filled with air.
Then, dropping the acceleration Fa is becomes greater than the material strength of the weak material portion 25, the weak material portion 25 absorbs the impact by discharging to the outside the enclosed air is broken. The shock absorbing material 20
As shown in FIG. 1 (b), it becomes a flat shape, and finally becomes a polymerized paper material.

衝撃をやわらげている。That is, if the gas-filled cushioning material between the article and the ground has a structure in which the weak material portion is broken by, for example, an impact of 15 G, the weak material portion is weakened from the point when the falling acceleration exceeds 15 G.
The material part 25 is broken, air is discharged from the inside of the bag to the outside, absorbing the falling acceleration, absorbing the residual impact force applied to the article, and relieving the impact.

In the case of a product, etc.
It is important in theory. In such a case, when unpacking,
When there is no cushioning material in which the weak material portion 25 is broken, there is no impact
It is determined that the weak material portion 25 has been broken and air has escaped.
When impact material was present, it was determined that a shock had occurred during handling.
I will tell. At this time, the cushioning material acts as a means for judging impact.
I do.

変形可能である。Further, as shown in FIG. 6 , a bonding portion 51 is formed by bonding the four sides, and a weak material portion 510 in which the strength is reduced in any of the materials is formed in the buffer material 50 in which the gas is sealed. At the same time, a point bonding portion 55 is formed in which the upper and lower materials (upper surface and lower surface) of the air bag are point bonded in a narrow range. The cushioning material 50 of this configuration has the strength of the weak material portion 510 and the point bonding portion 5
If you weaken the adhesive strength of 10, when external force is applied,
Absorb the external force first gas spot gluing unit 55 is a buffer material 50 to break to flow, weak material portion 5 further external force is strong
10 absorbs external force by breaking and extracting gas to the outside. Thus, the cushioning material 50 absorbs external force in two stages. The shape of the cushioning material can be appropriately changed to a round shape or a triangular shape.

Since the external force is absorbed by pulling out from the material part,
The impact force is not transmitted to the items contained in the package.

By breaking the trapped gas and evacuating the trapped gas to the outside, it is possible to absorb the impact, obtain a sufficient cushioning force without providing a dedicated cushioning design for each product, and easily perform the packing operation. In addition, whether or not a shock is applied to the contained articles during handling is a proof of the impact history when there is a buffer material from which the enclosed air is evacuated, and the articles can be easily managed.
