Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a shock absorbing device for packaging, and is designed to enhance the shock absorbing effect at the corners of the article, particularly when packaging heavy articles.

Conventional technology Traditionally, when packaging goods such as electrical equipment,
As shown in FIG. 1, cushioning bodies 2 are fitted into the four corners of the article 1 to be packaged, and in this state the article 1 and the cushioning bodies 2 are stored in a packaging case 3 made of cardboard or the like. .

Particularly when the weight of the article 1 is large, the cushioning body 2 shown in FIGS. 2 and 3 is used. That is, the cushioning material 4 is made of a relatively soft material such as foamed plastic and has three mutually orthogonal surfaces (however, in this example, the cushioning material 4 has a total of four surfaces because it is configured symmetrically). , a reinforcing member 5 made of a relatively hard material such as cardboard or pressboard is attached to the two outer surfaces, and a reinforcing member 6 made of cardboard, pressboard, etc. is attached to the entire inner surface thereof. It is. Incidentally, FIG. 3 shows a developed view of the inner reinforcing member 6, and 6a, 6b, and 6c indicate the surfaces that come into contact with the three surfaces of the corners of the article 1, respectively. Also, 6d is the surface 6 due to the notch 6e.
It is a surface separated from the surface 6c, and as shown in FIG.
can be pasted on. If such a shock absorber 2 is used, a sufficient shock absorbing effect can be obtained by the action of the soft buffer material 4 in the center and the hard reinforcing members 5 and 6 on the outside and inside of the soft buffer material 4. 5,6
Since the cushioning material 4 is attached to the cushioning material 4, even if the central cushioning material 4 is destroyed by the impact of the fall, the pieces will not scatter.

Problems to be Solved by the Invention However, when the article 1 is stored in the packaging case 3 using the cushioning body 2 according to the conventional technology,
If the packaging case 3 is dropped from a corner in this state, there is a problem in that a large impact is applied to the corner of the article 1 because the load is concentrated on one corner of the article 1 . In particular, when the strength of the inner reinforcing member 6 is high, there is a problem in that the impact that cannot be absorbed by the outer reinforcing member 5 and the cushioning material 4 is applied directly to the article 1, resulting in the corner of the article 1 being crushed. .

The present invention provides a shock absorbing device that solves these conventional problems with a simple configuration.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention uses a cushioning material made of a relatively soft material such as foamed plastic and having three mutually orthogonal surfaces, a cardboard, The cushioning body is made of a relatively hard material such as pressboard, and includes a reinforcing member attached to at least a part of the outside and the entire inside of the cushioning material, and the cushioning body is used to connect the packaged article and the packaging material. disposed between the cases, the inner and outer reinforcing members are configured to abut around corners of the article to be packaged and the packaging case, respectively, and a portion where three surfaces of the inner reinforcing members intersect; A through hole is formed across three sides of the cushion, and the cushioning material is exposed through the through hole.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 4 and 5.

In FIGS. 4 and 5, parts having substantially the same functions as those in FIGS. 1 to 3 are denoted by the same reference numerals, and explanations thereof will be omitted. 6f is 3 of the inner reinforcing member 6
Three surfaces 6 are placed at the intersection of the three surfaces 6a, 6b, and 6c.
It is a circular through hole provided across a, 6b, and 6c, and is punched so as to be continuous with the notch 6e when punching the notch 6e, as shown in FIG.

In this way, when the article 1 is stored in the packaging case 3 together with the cushioning material 2 and the packaging case 3 is dropped from a corner, the corner of the article 1 passes through the through hole 6f directly into the cushioning material 3. corresponds to At this time, since the cushioning material 4 is made of a soft material, the load concentrated at one corner of the article is buffered to some extent by the cushioning material 4. Next, the three surfaces 6 of the inner reinforcing member 6 are attached to the three surfaces around the corners of the article 1.
a, 6b, and 6c abut over a relatively wide area. At this time, the corners of the component 1 have already received a buffering effect from the cushioning material 4, so the buffering force applied to the entire corner is small. 6c to the surface around the corner of the article 1.
It is possible to reliably prevent breakage of the corners.

6 and 7 show another embodiment of the present invention, in which both ends of the cushioning body 2 shown in FIGS. 3 and 4 are separated and used as a separate cushioning body 2 for the article 1. Each corner is fitted separately. In this case as well, the three surfaces 6 of the inner reinforcing member 6
Three surfaces 6a, 6 are located at the intersection of a, 6b, and 6c.
A similar effect can be obtained by providing a through hole 6f spanning b and 6c.

In addition, the through hole 6f may be rectangular, triangular, or rectangular in addition to circular.
It may be an oval shape, but if it is made too large, the strength of the inner reinforcing member 6 will be weakened, so it is necessary to keep it within a certain limit.

Furthermore, the outer reinforcing member 5 may be attached to two surfaces of the cushioning material 4 as shown in FIG. 4, or may be attached to three surfaces of the cushioning material 4 as shown in FIG. .

Effects of the invention As described above, the present invention configures a cushioning material by attaching reinforcing members to the entire outer and inner surfaces of a cushioning material having three mutually orthogonal surfaces, and
A through hole is formed across the three surfaces at the intersection of the three surfaces, and the cushioning material is exposed through this hole, so the cushioning material can be placed between the corner of the article to be packaged and the corner of the packaging case. Even if the packaging case is dropped from the corner in this state, the load concentrated at one point on the corner of the article is effectively absorbed by the cushioning material and the inner reinforcing member. It can provide cushioning and reliably prevent the corners of the article from breaking. Furthermore, since the reinforcing member is attached to the entire inner surface of the cushioning material, there is no possibility that the cushioning material will be destroyed and scattered due to impact.
