Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foam cushioning material for packaging which can be easily treated after use.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional example of a foam cushioning material made of expanded polystyrene and the like, and a usage pattern thereof. In this figure, 31 is an upper cushioning material, 32 is a lower cushioning material, 1
01 is an article (object to be packaged).

However, in such a use form, there are problems that the foam cushioning materials 31 and 32 are large in size, the amount of foaming material used is large, and the disposal of the foam cushioning material after use is troublesome.

In order to eliminate this problem, as shown in FIG. 4, in many cases, foam cushioning materials 41 (upper cushioning material) and 42 (lower cushioning material) are used only at the corners of the article 101. However, in such a usage mode, since the foam cushioning material 41 on the upper side is not stably fixed to the article 101, the foam cushioning material 41 is displaced from the article 101 during transportation,
There was a problem of falling out.

Further, in order to eliminate the above-mentioned problems, as shown in FIG. 5, a packaging method has been adopted in which upper foam cushioning materials 51, 51 are connected and fixed by a connecting member 53. As another packaging method, as shown in FIG.
The packaging method is also adopted in which the upper foamed cushioning material is prevented from being displaced or dropped from the article 101 by increasing the dimension of No. 1 and increasing the area in contact with the article 101 without using the connecting component 53. It has been. In FIGS. 5 and 6, 52 and 62 are foam cushioning materials on the lower side.

[0006]

However, the packaging method using the connecting parts 53 as shown in FIG. 5 causes an increase in packaging cost and an increase in the number of man-hours for packaging as compared with the case where only the foam cushioning material is used. It was not an effective means because it might invite.

Further, in the method using a foam cushioning material having a large size as shown in FIG. 6, as a result, as in the foam cushioning material of FIG. It was Further, if a large foam cushioning material as shown in FIG. 3 is forcibly divided in order to make it a size that can be easily processed, it will not be uniform in shape and small pieces will be generated, which is rather time-consuming to dispose. There was also a problem.

The present invention is intended to solve the above problems associated with foam cushioning materials having large dimensions as shown in FIGS. 3 and 6, and the purpose thereof is to easily divide into a certain shape. Therefore, a foam cushioning material that is easy to dispose of after use,
It is to provide with a simple configuration.

[0009]

The foam cushioning material for packaging according to claim 1 is characterized by having a dividing groove which can be divided into small pieces for easy post-use treatment.

A foam cushioning material for packaging according to a second aspect is the cushioning material according to the first aspect, characterized in that it can be divided into a constant shape in the dividing groove.

A foam cushioning material for packaging according to a third aspect is the cushioning material according to the first or second aspect, characterized in that a display portion showing the dividing groove is provided.

[0012]

According to the foamed cushioning material of the first aspect, it can be easily divided by bending it in the dividing groove. Therefore, later disposal becomes easy.

In the foamed cushioning material of the second aspect, the foamed cushioning material can be divided into a certain shape, so that the subsequent disposal becomes extremely easy.

In the foamed cushioning material of the third aspect, since it is specified that the predetermined groove is a dividing groove, the dividing work can be performed without any mistake.

[0015]

Embodiments of the present invention will now be described with reference to the drawings. Embodiment 1 (Claims 1, 2 and 3) The foam cushioning material 11 shown in Fig. 1 is provided with a dividing groove 1 at an appropriate position of the foam material constituting the foam cushioning material 11 so that the foam cushioning material 11 can be easily and uniformly fixed. A display unit 2 that allows the shape to be divided and that shows the groove 1 (a display unit that indicates the position of the groove 1 and that the foam cushioning material can be divided in the groove 1)
It is marked with.

Embodiment 2 (Claims 1, 2 and 3) The foam cushioning materials 21 and 21 shown in FIG. 2 have a shape and dimensions obtained by previously dividing the foam cushioning material 11 of FIG. 1 into two. Other configurations are the same as those in FIG.

[0017]

As is apparent from the above description, claim 1
According to the configuration, the foamed cushioning material having a large size can be divided easily and without producing fine pieces. Therefore, the disposal after use becomes easy. According to the configuration of claim 2, in addition to the effect of claim 1, since the foam cushioning material can be divided into a certain shape, the disposal after use becomes extremely easy. According to the configuration of claim 3, since the display portion showing the dividing groove is provided, the display device according to claim 1 or 2 is provided.
In addition to the effect of, the division work can be surely performed.
