のである。2. Description of the Related Art A cushioning body made of a foamed resin molded product is generally used for packaging electric products and replacement parts for OA equipment. These buffers are used by being fitted to the end of the packaged object, and fix the packaged object in the individual packaging box at the same time,
It protects the object to be packaged from external impacts such as drops and collisions.

のである。FIG. 3 shows an example of a conventional buffer body. In the figure, 1'is a buffer, 2 is a holding part, 3 is a buffer, and 5 is an object to be packaged. As shown in FIG. 3, the normal cushioning body 1 ′ is fitted to the article to be packaged 5 and the holding portion 2 for fixing the cushioning body 1 ′ to the article to be packaged 5, and when a shock is applied from the outside, It has a cushioning portion 3 that absorbs an impact due to its own compression or damage and reduces the impact transmitted to the holding portion 2. In this figure, the buffer portion 3 is provided only in the Z direction,
The buffer section 3 is appropriately formed at a site requiring a buffer capacity.

でこれを防いでいる。In FIG. 4, the area around the buffer portion 3 of the buffer body 1'is indicated by X.
The figure seen from the -Z plane is shown. The arrow C in the figure is the falling direction in which the cushioning portion 3 exhibits a cushioning capacity. As shown in FIG. 4, the buffer portion 3 is usually formed so that the cross section in the direction perpendicular to the holding portion 2 has a trapezoidal shape. Since the cushioning portion 3 projects from the holding portion 2, it easily breaks at its root portion, and the wide bottom surface prevents this.
【０００５】緩衝体１’の設計時には、求める緩衝能に

丁度半分の高さの断面積をもって受圧面積Ａとする。こ
れらＴ及びＡは、被包装物重量（Ｗ）、落下高さ
（Ｈ）、許容Ｇ値（Ｇ）より次式により算出される。When designing the buffer 1 ', the buffer thickness T and the pressure receiving area A of the buffer 3 are calculated according to the required buffer capacity. The buffer thickness T is the height T of the buffer section 3 shown in FIG.
The pressure receiving area A is a cross-sectional area in a direction parallel to the holding portion 2. As described above, the buffer section 3 has a trapezoidal vertical cross section,
The pressure receiving area A has a cross-sectional area of exactly half the height. These T and A are calculated by the following formula from the weight (W) of the packaged object, the drop height (H), and the allowable G value (G).
【０００６】Ａ＝Ｗ×Ｇ／σ Ｔ＝Ｃ×Ｈ／Ｇ ここで、Ｃは緩衝体の素材に固有の定数である。A = W × G / σ T = C × H / G where C is a constant peculiar to the material of the buffer body.

Ｃ＝２．７、σ＝３の場合、受圧面積Ａ＝２４ｃｍ2 、
緩衝肉厚Ｔ＝５．４ｃｍである。For example, when the weight of the packaged object is 2.4 kg, the drop height is 60 cm, the allowable G value is 30, the material constant C of the buffer is C = 2.7, and σ = 3, the pressure receiving area A = 24 cm 2 ,
The buffer wall thickness T is 5.4 cm.
【０００８】[0008]
【発明が解決しようとする課題】上記式より、緩衝能を
高めるためには緩衝部の断面積を狭くし、緩衝肉厚の大
きい、細長い形状にすれば良いことがわかる。From the above equation, it can be seen that in order to enhance the cushioning capacity, the cushioning section may have a narrow cross-sectional area and a slender shape having a large cushioning thickness.

り容易に座屈してしまう。However, in actuality, a cushioning body having various cushioning portions is formed and its cushioning ability (G value related to the packaged object) is formed.
When measuring, the buffer capacity as designed may not be obtained. This is because as the shape of the cushioning part becomes thinner and longer, the cushioning part bends during impact and escapes from compression (buckling).
This is because, as a result, the impact is transmitted to the object to be packaged without performing the predetermined compression. In particular, when the falling direction is a corner or a ridge that is inclined with respect to the cushioning portion, the buckling will occur more easily.

時に所定の緩衝能を発揮できなくなってしまう。Further, even when no shock is applied, the cushioning portion located under the packaged article is subjected to the weight of the packaged article, so that the cushioning section is deformed by creep, and a predetermined cushioning is provided at the time of impact. It will not be able to exert its ability.

う。When the object to be packaged is heavy, the buffer part can be thickened within the range of the required cushioning capacity to prevent deformation and buckling of the buffer part. However, when the object to be packaged is light, the deformation and buckling can be prevented. Sufficient cushioning capacity cannot be obtained in the cushioning portion that does not buckle.

適に用いられる。SUMMARY OF THE INVENTION The present invention relates to a cushioning body having a holding portion that fits into an article to be packaged and holds the article to be packaged, and a buffer portion that projects from the holding section. At least one end of the portion has a support portion extending leftward and rightward around the end portion of the buffer portion so as to have a substantially T-shaped cross section in the direction parallel to the holding portion and protruding obliquely from the holding portion. It is a buffer body characterized in that. The present invention, as described above,
The purpose is to protect a lightweight object to be packaged, and specifically, it is suitably used for an object to be packaged of 3 kg or less, preferably 1 kg or less.

In the figure, reference numeral 1 denotes a cushioning body of the present invention, which has a holding portion 2, a cushioning portion 3, and a supporting portion 4. FIG. 2A shows a view of the vicinity of the buffer section 3 of the present embodiment as seen from the XZ plane. FIG. 2B is a sectional view taken along the line AA ′ in FIG.

斜して突出している。In the present invention, the buffer section 3 is conventional,
It is characterized in that T and A are set on the basis of the above-mentioned formula, and further, the support portion 4 for supporting the buffer portion 3 is provided at one end of the buffer portion 3. The support portion 4 according to the present invention extends laterally around the end portion of the buffer portion 3 and has a substantially T-shape in cross section (FIG. 2 (b)). At the same time, the supporting portion 4 is inclined and protrudes from the holding portion 2.

ることができるのである。In the present invention, since the support portion 4 exists at the end portion of the buffer portion 3, the buffer portion 3 cannot be bent,
Therefore, conventional buckling is prevented. In addition, this support portion 4
Since the slopingly protrudes from the holding portion 2, when it receives an impact, it falls toward the cushioning portion 3 side and is not compressed like the cushioning portion 3. That is, since there is no cushioning action, the pressure receiving area A is only the shaded portion in FIG. 2B, and it is not necessary to make the cushioning portion 3 thin by providing the supporting portion 4. Therefore, in the conventional thin or long buffer,
It is possible to reliably obtain the designed cushioning capacity that was not obtained due to buckling or the like.

３の圧縮が妨げられてしまうため、好ましくない。In the present invention, the inclination angle of the support portion 4 is
The thickness of the support portion 4 is t 1 , and the shift of the support portion 4 in the X direction is t 1 .
When a 2, t 2 = 2~5t 1 is desirable. The inclination angle of the support portion 4, that is, the angle formed by the support portion 4 and the holding portion 2 is 90.
When the angle is close to 0, the cushioning effect is exhibited, and the pressure receiving area of the cushioning portion 3 must be reduced accordingly. Also, if the inclination angle is small, the collapsed support portion 4 becomes an obstacle and the compression of the buffer portion 3 is prevented, which is not preferable.

ない。In this embodiment, the supporting portion 2 is partially parallel to the Z direction at the end portion of the supporting portion 4 opposite to the holding portion 2. This is because it becomes a ridge, and there is no problem even if the inclined surface is extended.

For example, expanded polyethylene, expanded polypropylene, and expanded polystyrene can be preferably used. Further, the buffer portions 3 and the support portions 4 may be separately molded from the same material or different materials and then bonded or fused to the holding portion 2 or integrally molded.

In the present embodiment, the support parts that are fitted from the left and right side surfaces of the packaged object and that support the buffer parts provided on the top and bottom surfaces and the support parts that support the buffer parts provided on the front surface are continuous. In this example, t 1 shown in FIG. 2A was set to 10 mm, and t 2 having different numerical values was prepared (to). The height of the buffer is 75mm
Is. On the other hand, the comparative example is a cushioning body that has conventionally packaged the article to be packaged, and the article to be packaged is fitted from the front-rear direction. The height of the buffer portions is 75 mm in each case.

The ridge formed by the bottom surface and the ridge formed by the left side surface / bottom surface were dropped in this order. As a result, good results were obtained without any damage to the objects to be packaged in Examples to Comparative Examples. Next, drop the same package in order of front, back, top, bottom,

る。As is clear from Table 1, all the examples exhibited low G values on average. Conventionally, when a buffer portion was formed with the pressure receiving area of this embodiment, the buffer portion buckled and did not exhibit a predetermined buffer capacity. According to the present invention, it is possible to sufficiently obtain the cushioning ability even with a cushioning portion having a narrow pressure receiving area.

に固定せずとも外れる心配がない。Further, in the comparative example, since the buffer body was about to come off the packaged object during the drop test, the buffer body was fixed to the packaged object with the adhesive tape. No such phenomenon was observed in the examples. This is because when the cushioning part on the top floor is crushed by the impact of a fall, it collapses inward (in the direction of the rear side of the cushioning part on the top bottom of the cushioning body fitted from the front side). This is because the force acts in the direction to remove it from the package. The buffer body of the embodiment does not fall inward due to the support portion. Therefore, the force always acts in the outward direction, that is, the direction in which the cushioning body is pressed against the article to be packaged, and there is no concern that the cushioning body will come off without being fixed to the article to be packaged.

It is possible to obtain a buffer capacity and prevent damage during transportation, transshipment, and the like.
