Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning device for protecting articles, and more particularly, when transporting and handling various machine parts, the parts or interior boxes (protective articles) containing the parts, and corrugated cardboard. The present invention relates to a shock absorber for protecting an article, which is interposed between an exterior body such as a box and absorbs impact energy such as impact or vibration of an external force applied to the exterior body to prevent the protective article from being damaged. .

[0002]

2. Description of the Related Art Conventionally, as a shock absorber for protecting articles such as home electric appliances, precision measuring equipment, information equipment, etc., which are averse to shock and vibration, during transportation and handling, they are molded according to the outer shape of the protected article. The foamed plastic block or corrugated cardboard that is cut or bent into an appropriate shape is interposed between the protective article and the exterior body.

Corrugated paperboard has a function of effectively absorbing impact energy by buckling deformation when a large impact force is applied, but since it is inferior in elastic deformability, it is a protective article. There is a gap between the outer case and the outer body, which may cause rattling, and vibrations may be transmitted to the protective article as it is, or the protective article and the shock absorber or surrounding objects may rub against each other and scratch the protective article. Therefore, there is a drawback that the protective article cannot be sufficiently protected.

On the other hand, since the foamed plastic has elasticity to some extent, it elastically abuts on the protective article,
It has the function of securely supporting the protective article at a fixed position so that it will not move even if vibration is applied, and when a large impact force is applied, it will cause permanent deformation like the corrugated paperboard. It also has a function of effectively absorbing impact energy and is suitable as a material for a shock absorber.

[0005]

However, even in the case of foamed plastic, once a large impact force is applied to cause permanent deformation, a gap remains with the protective article and the protective article becomes elastic. The function of abutting and supporting at a fixed position cannot be fulfilled. Therefore, the shock absorber using the foamed plastic is not always sufficient in terms of the protection function of the article. In addition, the shock absorber that has undergone such permanent deformation cannot be reused even if it is recovered after use.

Therefore, the conventional shock absorber made of foamed plastic is not used after transporting protective articles.
It was discarded as it was, but it was very uneconomical and wasted resources. Moreover, the foamed plastic is bulky and difficult to weather, and is not suitable for disposal by burying. In addition, when incinerating and discarding, there are problems that high heat is generated and the incinerator is damaged, or toxic gas is generated to pollute the environment.

The present invention solves the above-mentioned problems of the conventional shock absorber, has a good protection function for protective articles, does not have a problem regarding disposal such as foamed plastics, and effectively uses resources and is economical. However, it is an object of the present invention to provide an excellent shock absorbing device for protecting articles.

[0008]

SUMMARY OF THE INVENTION An article protecting and cushioning device according to the present invention comprises an elastic bag cushioning member made of a spherical or annular elastic bag cushioning member and a columnar cushioning member made of a paper tube cushioning member such as a paper tube or corrugated cardboard. To form a shock absorber, and the shock absorber is disposed between the protective article and the exterior body, and the impact energy applied to the exterior body from the outside by frictional force between the paper materials of the paper tube cushion body is mainly used. It is characterized by absorbing.

Here, the elastic bag cushioning material composed of an elastic bag cushioning body (hereinafter referred to as an elastic bag cushioning body) is a flexible spherical or annular bag formed of an elastic material such as rubber, that is, an elastic bag cushioning body. Is filled with air and sealed, and utilizes the elastic cushioning effect of the filled air. As for the shape of the elastic bag cushion, a spherical one is easy to manufacture and has an excellent cushioning effect, and it is easy to place it stably at the tip of the paper cylinder cushion. Planar shapes and other shapes are used. If the elastic bag cushion is attached so that it fits snugly into the tip of the paper tube cushion described later, it will not move or shift without special fixing means, but the elastic bag cushion It is also possible to provide a temporary fixing means for detachably fixing the to a columnar cushioning material (hereinafter referred to as a paper cylinder cushioning body) made of a paper cylinder cushioning body. As this fixing means, a double-sided adhesive tape or various engaging structures can be adopted. If the air bag supply / exhaust valve is provided in the elastic bag cushion, the air pressure of the closed air can be changed to adjust the elastic deformation characteristics, and the size can be reduced by removing the air when not in use. .

Next, the paper-cushion cushioning body is formed of a paper material such as thick cardboard or corrugated cardboard, which has a relatively high rigidity, and has a magic member between the inner cylinder and the outer cylinder wound in a cylindrical shape or a polygonal cylinder shape and having different diameters. It is bonded with tape, double-sided tape, adhesive material, or adhesive. When the positions of the inner cylinder and the outer cylinder are displaced, a large impact force can be absorbed by the frictional force generated in the adhesive layer between them. By using a plurality of paper cylinders having different diameters that are concentrically stacked, it is possible to absorb a larger impact force. In addition, the paper material may be wound not only in a single layer but also in multiple layers according to the magnitude of the impact force. The seam of the paper material wound in a tubular shape is permanently or temporarily fixed by a common fixing means such as a double-sided tape, an adhesive material, or an adhesive.

Further, the paper-cushion cushioning body may be provided with a fixing means for fixing it to the inner surface of the exterior body or the surface of the protective article so as not to shift or move during use. As the fixing means, the same double-sided tape as described above and the fixing means used in ordinary shock absorbers and packages are used. It is convenient if a flat portion is provided at the end of the paper-cushion cushioning body so that a double-sided tape can be attached or an adhesive can be applied. Further, if the surface of the protective article or the exterior body and the paper-cushion cushioning body are provided with engaging portions that can be engaged with each other, the paper-cushion cushioning body can be detachably fixed.

[0012]

According to the present invention, the paper-cushion cushioning body can satisfactorily absorb the impact force mainly due to the frictional force generated in the adhesive layer between the paper materials when the paper cylinder is displaced, while the elastic bag cushioning body is
Since it is elastically deformed and restored, it is possible to absorb vibration and the like satisfactorily and to elastically contact the protective article.

Therefore, if the elastic bag cushioning body is arranged at the tip of the paper tube cushioning body, the elastic deformation of the elastic bag cushioning body can fill the space between the exterior body and the protective article exactly and without any gap. The cushioning device elastically abuts the protected article, and the article can be reliably supported at a fixed position so that the article does not shift or move. In this state, if vibration or a relatively small external force is applied, it can be satisfactorily absorbed by elastic deformation of the elastic bag cushioning body.

However, when a large impact force is instantaneously applied, the elastic bag cushioning body is easily deformed, so that the impact energy cannot be absorbed so much. However, when the positions of the inner cylinder and the outer cylinder of the paper-cushion cushioning body are displaced, a large impact force can be absorbed by the frictional force generated in the adhesive layer between the paper materials. It is possible to reliably absorb a large impact force and prevent the impact force from being transmitted to the protective article.

Even if the paper-cushion cushioning body is permanently deformed due to the displacement, if the elastic bag cushioning body is elastically restored, the protective article is supported again at the stable position. This is because the elastic restoration amount of the elastic bag cushioning body filled with air is much larger than the shift deformation amount of the paper tube cushioning body.

That is, in the present invention, by utilizing the characteristics of the elastic bag cushioning body which is excellent in the vibration absorbing performance and the function of supporting the protective article and the paper cylinder cushioning body which is excellent in the absorbing force of the impact force, both performances are achieved. A shock absorber that can be used will be obtained.

After the shock absorber is used for transporting and storing the protective article, even if it is necessary to discard the paper-cushion cushioning body that has been displaced and deformed, the elastic bag cushioning body only elastically deforms. Can also be reused. Therefore, it is possible to repeatedly use the paper cylinder cushioning body which is made of paper material and is relatively inexpensive. If the unfolded paper cylinder cushioning body is expanded, the size will be very small,
Moreover, since it is easy to incinerate, it can be easily disposed of.

FIG. 1 is a perspective view of a main part of a first embodiment of the present invention, in which an elastic bag cushioning material composed of a spherical spherical elastic bag cushioning body 2 made of rubber and cardboard are rolled into a cylindrical shape. The cushioning device 1 is configured by combining it with a columnar cushioning material formed of the paper tube cushioning body 3.

The spherical elastic bag cushion 2 is provided with a supply / exhaust valve 2A capable of letting air in and out, and is filled with air of a predetermined pressure.

As shown in the sectional view showing the usage state of FIG. 2 and the plan view of FIG. 3, the paper-cushion cushioning member 3 has an inner cylinder 31 and an outer cylinder 32.
And both are joined by an adhesive 33 such as a velcro tape, a double-sided tape, or an adhesive material.

As shown in FIGS. 1 and 2, the shock absorber 1
When using, the exterior body 4 consisting of a cardboard box, etc.
The shock absorber 1 is arranged at an appropriate place such as the four corners of the inner bottom surface 4A. As shown in FIG. 2, first, the outer cylinder of the paper cylinder cushioning body 3
32 is the inner bottom surface 4A of the exterior body 4 with double-sided tape or adhesive
If it is fixed to, it will be surely positioned. If the spherical elastic bag cushioning body 2 is placed on the upper end of the inner cylinder 31 of the paper tube cushioning body 3, there is no concern that the spherical elastic bag cushioning body 2 will move or fall off. However, the spherical elastic bag cushion 2 is attached to the paper cylinder cushion 3 with an adhesive or the like.
It may be temporarily fixed to the inner cylinder 31 of.

On the spherical elastic bag cushion 2 of the shock absorber 1,
An article such as a machine part or an inner box 5 (hereinafter referred to as a protective article) accommodating the article is placed, and after the outer case 4 is sealed, the article is used for transportation and storage. Although not shown, the shock absorber 1 may be attached to the inner surface of the exterior body 4 on the side surface side or the upper surface side of the protective article 5.

When transportation or the like is performed in this state and an external force is applied, vibration and a small external force are favorably absorbed by the spherical elastic bag cushion 2. However, when a large impact force is applied, the spherical elastic bag cushion 2 is easily deformed, so that the impact energy cannot be absorbed. However, when the impact force comes to be directly applied to the paper tube cushioning body 3, the inner cylinder 31 and the outer cylinder 32 of the paper tube cushioning body are displaced and deformed, so that the impact force is well absorbed, and thus the protective article. It is possible to securely protect 5 without being greatly shaken or moved. If the impact force disappears,
Even if the inner cylinder 31 and the outer cylinder 32 of the paper-cushion cushioning body 3 are left displaced and deformed, the spherical elastic bag cushioning body 2 is elastically restored to return the protective article 5 to its original position.

When the transportation of the protective article 5 is completed, after removing the protective article 5 from the outer package 4, the spherical elastic bag cushion body 2 is removed from the upper end of the paper tube cushion body 3, and the paper tube cushion is deformed and deformed. The inner cylinder 31 and the outer cylinder 32 of the body 3 may be discarded together with the exterior body 4 or removed from the exterior body 4.
The spherical elastic bag cushion 2 can be reused in combination with the new paper tube cushion 3 again. When the spherical elastic bag cushioning body 2 is transported or stored to a reuse place, air is extracted from the air supply / exhaust valve 2A to keep the spherical elastic bag cushioning body 2 in a flat state. The size is small and handling is easy, and transportation and storage costs can be reduced.

Next, FIG. 4 shows a plan view of a paper tube cushioning body according to a second embodiment of the present invention.

In this embodiment, the same spherical elastic bag cushion 2 as in the first embodiment is used, and the inner cylinder of the paper cylinder cushion 3 is used.
The outer cylinder 35 and the outer cylinder 35 are joined together with an adhesive 33, and the ends of the cylinders are overlapped at the portion A. Specifically, when the inner and outer cylinders 34 and 35 are simultaneously wound with thick paper or corrugated paper while being positioned with an adhesive 33 such as a velcro or double-sided tape, an integrated paper cylinder cushion 3 is obtained.

FIG. 5 is a cross-sectional view of a main part showing a use state of the third embodiment of the present invention, in which a rubber donut-shaped annular elastic bag cushion 6 and a paper material such as cardboard or corrugated paper are cylindrical. The cushioning device 1 is configured by the paper-cushion cushioning body 3 that is rolled into a shape.

The annular elastic bag cushion 6 is provided with a supply / exhaust valve 6A capable of letting air in and out, and is filled with air of a predetermined pressure.

The paper-cushion cushioning body 3 is composed of an inner cylinder 31 and an outer cylinder 32 wound in a cylindrical shape or a polygonal cylinder shape and having different diameters, and both are bonded with a velcro tape, a double-sided tape, an adhesive material or the like. Bonded by Agent 33. The paper-cushion cushioning body 3 constituting this cushioning device and the annular elastic bag cushioning body 6 are arranged on the inner bottom surface 4A of the exterior body 4 so as to be sandwiched between both sides.
The protection article 5 is placed on the annular elastic bag cushion 6. If an external impact force is applied to the outer casing 4, this inner cylinder
A large impact force can be absorbed by the frictional force generated in the adhesive layer between the paper materials when the positions of 31 and the outer cylinder 32 are displaced.

FIG. 6 is a sectional view showing a use state of the fourth embodiment of the present invention. The spherical elastic bag cushion 2 has the same structure as that of the first embodiment, and the paper tube cushion 3 is shown. Is adhered to the side surface 4B of the exterior body 4 by an adhesive 33 such as a velcro tape, a double-sided tape, or an adhesive material. A large impact force can be absorbed by the frictional force generated in the adhesive layer when the positions of the paper-cushion cushioning body 3 and the exterior body 4 are displaced.

[0031]

As described above, the cushioning device for protecting articles according to the present invention includes an elastic bag cushioning body capable of reliably supporting a protected article at a fixed position and absorbing a relatively small force such as vibration. Good protection of the article can be achieved by using a combination of paper-cushion cushioning bodies that can absorb a large impact force due to the frictional force caused by the shear deformation.

Particularly, in the conventional shock absorber made of paper or foamed plastic, if a large impact force is applied to cause permanent deformation of the material, there is a gap between the protective article and the shock absorber to cause rattling. After that, the protective article will be damaged, and the article will not be able to be properly buffered and protected. However, in the present invention, even after the paper-cushion cushioning body is displaced and deformed, the function of the elastic bag cushioning body is exerted without any change, so that the cushioning protection of the article can be sufficiently achieved.

Since the paper-cushion cushioning body and the elastic-bag cushioning body are composed of separate parts, the elastic-bag cushioning body can be used repeatedly even if the paper-cushion cushioning body that has undergone permanent deformation needs to be replaced. Therefore, the paper-cushion cushioning body made of a paper material is very economical in combination with the low cost. Further, since the paper-cushion cushioning body can be easily disposed of by disposal such as incineration, there is no trouble in disposing like the conventional foamed plastic.
