Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a shock absorbing device for packaging articles for holding and fixing articles against impact in an article storage box.

<Conventional technology> Conventionally, when packaging lightweight products that are susceptible to impact, such as floppy disk devices or hard disk devices, as shown in Figure 3, a thick polyurethane foam or the like is placed around the product G to be packaged. A number of layers of square plates 42 and 43 made of synthetic resin having elasticity were stacked one on top of the other. Alternatively, as shown in Figure 4,
The article G was supported from both sides by a cushioning material 44 having eight arms.

<Problems to be Solved by the Invention> The method shown in FIG. 3 described above has the drawback of increasing costs because flexible synthetic resins having elasticity such as foamed polyurethane are expensive. In addition, in the method shown in Figure 4, in order to improve the cushioning performance against low impacts, it is necessary to make the cushioning material that is in contact with the outer box thin and long. It becomes difficult to mold or cut out the mold. Another problem has been that the lighter the product, the more difficult it is to fix it.

<Means for Solving the Problems> The present invention provides a structure that is fixed to opposing walls of a support inside a packaging box and extends toward the center of the packaging box. A cushioning material having both arms that clamp an article, each arm having a protrusion projecting in a direction away from the clamping position of the article, and an arm of the cushioning material. The engaging member has an opening that is fitted into the protrusion of the part, and engages with a cushioning material that surrounds and faces the article to be packaged, and the engaging member engages with the cushioning material to wrap the article. It is characterized by being supported inside a packaging box.

<Function> After the article to be packaged is sandwiched between the arms of the cushioning material facing each other, the article is surrounded by the engaging member, and each opening of the member is fitted into the protrusion of the cushioning material. , the article is elastically supported by the support body while being surrounded by the engaging member. Then, by fitting the support into the packaging box, packaging of the article is completed.

<Example> FIG. 1 shows an exploded perspective structure of a shock absorbing device for packaging articles according to this example. 1 is a support body, 2 is a cushioning material, and 3 is an engaging member.

The U-shaped support 1 is fitted into a packaging box (not shown).

Two cushioning materials 2 are fixed to each of the opposing walls 11 and 12 inside the support 1 by adhesive. This cushioning material 2 has both arm parts 21 which extend toward the center of the support body 1 while being fixed to the wall parts 11 and 12, respectively, and which hold the article G to be packaged. The article G is held in the gap d between both arms 21. Both arm portions 21 have protrusions 22 in the vertical direction in the figure at their distal ends. The cushioning material 2 is formed by processing and molding a low-cost synthetic resin such as foamed polyethylene by punching with a Thomson blade or the like.

The engaging member 3 is formed by bending corrugated paper. This engaging member 3 is formed by folding corrugated paper into a rectangular tube shape, and has four openings 31 on each of the upper and lower surfaces in the figure.

When packaging the article G, first, the engaging member 3 is bent to surround the article G while the article G to be packaged is held between both arms 21 of the cushioning material 2 facing each other from both sides, and the opening is opened. 31 is fitted into the protruding portion 22 of the opposing buffer material 2. Then, the end portion of the engaging member 3 is fixed with adhesive tape or the like.

FIG. 2 shows a state in which the article G is supported by the cushioning material 2 and the engaging member 3 surrounds the article G, and the cushioning materials 2 on both sides are engaged. In this state, the opposing cushioning materials 2 are firmly engaged by the engaging members 3, and it is possible to prevent the article G from falling off from the cushioning materials 2 when the support body 1 is tilted. Then, the U-shaped support 1 supporting the article G is fitted into the packaging box, thereby completing the packaging of the article G.

The cushioning material 2 is provided inside the support body 1 in only one direction. A shock applied in a direction different from the direction of the cushioning material 2 can be cushioned by the spring effect of the cushioning material 2 in the vertical and horizontal directions.

<Effects of the Invention> As explained above, in the present invention, a cushioning material having both arms that clamps an article in one direction from both sides inside a packaging box is engaged by surrounding the article with an engaging member. As a result, the structure of the cushioning material is simplified, and inexpensive synthetic resin can be processed and molded by punching or the like, resulting in cost reduction.
