Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for protecting products and parts from shocks during transportation.

[0002]

2. Description of the Related Art Generally, when packing various products or parts, the products are held by a styrofoam having a recess matching the shape of the product to be packed and stored in a cardboard box or the like.

[0003]

In the case of the above-mentioned conventional technique, in order to mold styrofoam, a molding material suitable for a predetermined raw material resin or product is required, and when packing a small number of products or a large number of different shapes When packaging the above products, the cost was high, and it was necessary to prepare various types of Styrofoam according to the shape of the products.

Further, when styrofoam is used, there is a problem in treating used styrofoam. That is, the only way to dispose of used Styrofoam is to incinerate or discard it.When incinerating, it burns black smoke at first and burns at a considerably high temperature later, which not only pollutes the environment but also incinerators. There is a problem of hurt. Further, even when thrown away, since the styrofoam is not decomposed naturally, it remains as dust that pollutes the environment. In addition, it is expensive to reuse,
Even if it is reused, it can only be reused once, and cannot be recycled multiple times.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a cushioning material having a simple structure and a high cushioning effect regardless of the shape of the product.

[0006]

SUMMARY OF THE INVENTION The present invention provides a box body such as a cardboard having an opening on one side surface, and expands or contracts a film or a net attached or attached so as to cover the opening. It is a cushioning material provided with a free covering member.

[0007]

In the cushioning material of the present invention, one end of the product to be held is pressed against the opening covered by the expandable cover member, the cover member is stretched by a part of the product and enters the opening, and the product is The cover member is elastically held.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a first embodiment of the present invention. As shown in FIG. 2, the cushioning material of this embodiment is a hollow rectangular box body 10 made of a thick paper material such as corrugated cardboard. A rectangular opening 12 is formed on one side of the box 10. The box body 10 is covered with a synthetic resin film 14, which is a stretchable covering member made of polyethylene or the like, so as to cover the entire surface of the opening 12 and wrap the whole box body 10.

The synthetic resin film 14 is made of, for example, a heat-shrinkable film, and wraps the box body 10 to enclose the opening 1.
After sealing 2, the synthetic resin film 14 is brought into close contact with the box 10 by passing it through a heating atmosphere, and the opening 12 is surely covered in a tensioned state. Further, a stretchable synthetic resin film 14 may be attached to the side surface of the box body 10 on which the opening 12 is formed.

The method of using the cushioning material of this embodiment is shown in FIG.
As shown in FIG. 3, a pair of cushioning materials are prepared so that the openings 12 face each other, the end surface of the product 16 to be packed is inserted into the openings 12, and in that state, it is put in a storage box or the like not shown. At this time, as shown in FIG. 3, the end surface of the product 16 is projected into the inside of the box 10 through the opening 12, and the elastic force of the synthetic resin film 14 attaches the product 16 in the direction in which the product 16 projects from the opening 12. It is supported and supported.

As a result, the product 16 is elastically supported by the synthetic resin film 14 in a hollow shape, and the product whose both ends are held by the two cushioning materials is put into a cardboard box or the like, so that the product is placed inside the cardboard box. Is reliably protected from impact.

According to the cushioning material of this embodiment, by setting the opening 12 of the cushioning material to a certain size, the product 16 to be held has an end portion that does not touch the opening 12. Any type of cushioning material can be used for packaging products of various shapes regardless of the shape of the product 16.

Further, by forming the box body 10 from cardboard or the like, the cushioning material can be recycled a plurality of times, and the cardboard paper itself is a paper that has undergone a plurality of recyclings, thus making effective use of resources. It is what further,
This cushioning material is easy to incinerate when treating waste and does not cause environmental pollution.

Next, a second embodiment of this cushioning material will be described with reference to FIG. Here, the same members as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. In the cushioning material of this embodiment, the pair of boxes 10 are brought into contact with each other with the openings 12 facing each other, and the synthetic resin film 14 attached to the openings 12.
The product 16 is sandwiched between and elastically supported.

According to this embodiment, in addition to the effects similar to those of the above embodiment, the product 16 is supported in a state of being completely sandwiched between the synthetic resin films 16 and is more reliably protected. It is also possible to hold a plurality of products 16 in the opening 12, and to make small parts into the opening 1.
It is also possible to arrange them on the synthetic resin film 14 in 2 and press the other cushioning material from above to sandwich and hold between the synthetic resin films 14 in the opening 12.

In the cushioning material of the present invention, a retractable net may be used as a covering member for covering the opening of the box body. The stretchable net can be arbitrarily selected from a fine mesh like a stocking material to a coarser mesh.

By using a net as a covering member for covering the opening, it is suitable as a cushioning material for products that require air permeability, such as eggs, and by selecting the material of the net, the strength and the like can be improved. It can be higher. The material of the box body may be resin or metal other than paper such as corrugated board.

[0018]

INDUSTRIAL APPLICABILITY The cushioning material according to the present invention is different from cushioning materials such as Styrofoam in that the shape of the product to be held is not selected,
It is extremely easy to manufacture. Also, after use, the box body is broken, so that it is not bulky for transportation and storage, so it does not take up much space for post-treatment. Furthermore, by using paper for the box, not only can it be reused, but it is also environmentally friendly when incinerated.
