Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging cushioning material used when any item is stored in a packaging container such as cardboard.

BACKGROUND ART Conventionally, as shown in FIG. 7, a cushioning material 2 made of polystyrene foam shaped to match the shape of the corner is attached to the corner of an article 1, and in this state, a packaging container such as a cardboard ( Packaging methods are well known.

However, this method has the disadvantage that the sizes of the packaging container and the item 1 are uniquely determined by the thickness of the cushioning material 2, and it is not possible to freely select between the two. For example, if the size of item 1 is constant, the packaging container that can be applied to it is limited to one that is larger than the size of item 1 by the thickness of cushioning material 2, and packaging containers of other sizes may be used. It is not possible.

Furthermore, if only one type of packaging container is available, only items of the corresponding size can be packed.

Problems to be Solved by the Invention In view of the above-mentioned points, the present invention makes it possible to pack any type of products with different sizes and shapes in one packaging container, and conversely, it is possible to pack one product in different sizes and shapes. Another object of the present invention is to provide a cushioning material that can be packaged in arbitrary packaging containers of different shapes.

Means for Solving the Problems The above objective is achieved by forming a plurality of protrusions that protrude radially along the axis and creating a cushioning material from a single flexible plate. be done.

Example The present invention will be explained below with reference to Examples.

FIG. 1 shows a perspective view of one embodiment. As shown in the figure, the cushioning material 5 according to this embodiment includes a plurality of (four in the figure) protrusions 4a that protrude radially along the axis l by one flexible plate 3,
4b, 4c, and 4d.

The plate material 3 is made of a flexible material, for example, a thermoplastic resin such as vinyl chloride, polyethylene, etc., or other synthetic resin.

Since the plate material 3 is flexible, the second
Projections 4a, 4b, 4c, 4 as shown by arrow A in the figure.
d can freely swing about the axis l, and can freely move toward or away from the axis l as shown by arrow B. Furthermore, the protrusions 4a to 4d themselves are also freely deformable.

When performing packing work using this cushioning material 5,
As shown in FIG. 3, several (four in the figure) cushioning materials 5 are placed between the item 11 and a packaging container 6 such as cardboard. Since the protrusions 4a to 4d can move elastically and freely as described above, they can be freely taken in and out even if there is a slight difference in width between the goods 11 and the container 6. Therefore, even if the sizes of the packaging containers 6 are different, cushioning materials 5 having the same shape can be used. Furthermore, even if the items 11 are slightly different in size, they can be packaged in packaging containers of the same size.

In the figure, the product 11 is packaged with its corners held between two protrusions 4c and 4d. In this case, these protrusions deform according to the external shape of the article 11 (in the directions A and B in FIG. 2 and deformation of the protrusions themselves), so that they can come into close contact with the article 11. Moreover, the article 11 is tightened by the elastic restoring force of these two protrusions. Therefore,
The item 11 is firmly held by these cushioning materials 5, and there is no fear of displacement.

The cushioning material 5 is attached to the article 11 as shown on the left side of FIG.
It may be provided over the whole area in the height direction, or it may be provided separately above and below as shown on the right side of the figure.
When the height of the item 11 is high, it is preferable to use it by dividing it into pieces like the latter. For convenience when using the cushioning material 5 in parts, perforations are made at appropriate locations on the cushioning material 5 as shown by chain lines lm in FIG. It can also be used by dividing it above and below the perforation.

In the above embodiment, the cushioning material 5 was attached to the corner of the item 11. However, the present invention is not limited to this, and the cushioning material 5 may be placed in the side portion of the item 11.

Further, in the above embodiment, the packaging container 6 having a rectangular cross section stores an article 11 having a rectangular cross section, but the present invention is not limited to this, and as shown in FIG. It can also be stored in a packaging container 6 having a rectangular cross section. Even in this case, since the protrusions 4a to 4d of the cushioning material 5 can be freely deformed, the adhesion between the article and the cushioning material is maintained well.

The shape of the tips of the protrusions 4a to 4d is not limited to the arcuate cross-sectional shape as in the embodiment, but may be a more acute-angled shape. However, if it is made into an arc shape as in the embodiment, it is advantageous in that there is no fear of damaging the item.

As shown in FIG. 2, the width of the protrusions 4a to 4c is
By making the base portion D narrow and the tip portion E wide, the protrusion can be easily deformed. Also, the protrusion 4
The length L of a to 4c from the axis l can be arbitrarily set depending on the shape of the packaging container and the product.

Note that the number of protrusions is not limited to four, and may be increased or decreased as necessary.

In the above embodiment, cushioning properties are obtained between the packaging container and the article, but as shown in FIG. If you put it in there, it can also provide cushioning between items. This buffer material 25 has three protrusions 24a, 24b, and 24c.

In addition, the large number of holes 7 provided in the protrusions 4a to 4d (only 4b and 4c are shown in the figure) in FIG. 1 are for venting air. These holes are intended to generate air flow between the inside and outside of the cushioning material 5 when an impact is applied to the packaging container 6, thereby increasing the cushioning properties.

The cushioning materials 5 and 25 can be formed integrally by well-known vacuum or pressure forming means, or by bending a single plate, or by various other methods.

Effects According to the present invention, since the plurality of elastically deformable protrusions provide cushioning properties to any item, the relationship between the size and shape of the item and the packaging container can be arbitrarily selected. .
