DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buffer for a package applied to a package to be stacked and a packaged product to be stacked.

[0002]

2. Description of the Related Art In general, a packaged product in which a rolled product coil or the like is packed in a packaged outer package, or a packaged product further tightened with a fastening band from above the packaged outer package. Various measures have been taken in handling to prevent this.

[0003] For example, when stacking a cylindrical package in which rolled product coils are packed with a packaging outer material in a two-stage stack or more in a down-end manner, when placing a higher-order package between lower-level packages, FIG. As shown in the figure, when the upper packaged product 5 is lowered in a state where the position shift t has been generated, the lower packaged product 5 is lowered.
After contacting with, since it is located between the lower packaged goods 5 while sliding, the packaging outer material 6 of the upper packaged product 5 or the lower packaged product 5 or both of the packaged products 5 may be damaged, In order to prevent breakage of the packing exterior material 6, a cushioning material 9
For disposing on the outer packaging material 6 (Japanese Utility Model Laid-Open No. 4-62882).
No., reference). By providing such a cushioning material 9, the packaging exterior materials 6 of the packaged product 5 do not directly contact each other, so that the packaging exterior materials 6 can be somewhat prevented from being damaged.

[0004]

However, the cushioning material 9
Normally, rubber or resin or the like is used for the purpose of reducing the impact force, so that the coefficient of static friction on the surface is high. Therefore, the upper packaged product 5 is strongly attached to the lower packaged product 5 via the cushioning material 9. When it comes into contact and slides, the cushioning material 9 is hooked by the frictional resistance at this time, and the hooking causes the damaged portion 10 to be formed in the packing exterior material 6 from the place where the cushioning material 9 comes into close contact with the cushioning material 9 of the lower packaged product 5 (FIG. 9). (See broken portion 10).

Similarly, the cushioning material 9 attached to the lower packaged product 5 and the package exterior material 6 of the upper packaged product 5 are caught by the package exterior material 6 of the upper packaged product 5 so that a damaged portion 10 is formed.
(See broken portion 10 in FIG. 10).

[0006] The above-mentioned problem does not occur if the upper package 5 can be lowered in a state of being accurately aligned and placed on the center between the lower packages 5, but in reality, loading on a ship,
It is difficult to lower the luggage in a state where the displacement is completely eliminated due to the swing of the luggage, the variety of the luggage's shape and size, and the like.

Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art, and it is an object of the present invention to reduce the catching force due to frictional resistance acting on a package exterior material of a packaged product to be stacked. It is an object of the present invention to prevent damage to a package exterior material of a packaged product to be stacked.

[0008]

SUMMARY OF THE INVENTION To solve the above technical problem, the present invention is directed to a method of mounting on the outer surface of a package to be stacked.
The present invention is characterized in that the coefficient of static friction μ of at least one of the front and back surfaces with respect to the contact portion with the outer surface of the package is 0.10 or less.

The specific configuration of the cushioning material for a packaged article is as follows.
A belt-shaped shock absorber main body having a sliding surface having a static friction coefficient μ of 0.10 or less with respect to a contact portion of an outer surface of a packaged product along at least one of the front and back surfaces. Good to be.

[0010] The means of the present invention as a packaged product includes:
Being stacked products, when stacking,
The coefficient of static friction μ of the contact portion on the outer surface of the package with the contact partner is set to 0.10 or less.

The packaged product may be a cylindrical product stacked in a down-end shape, and the contact portion is provided on an outer surface of any of a package exterior material of the packaged product, a fastening band, and a cushioning material attached to the packaged product. It may be formed of a sliding tape or a packing cushion attached to the outer surface of the package, and if necessary, if the contact portion is formed of a cushion for packing, It is desirable that the cushioning material for a packaged product is slidably attached to a package exterior material of the packaged product.

[0012]

The static friction coefficient according to the present invention (0.10 or less)
Was obtained as follows. As a result of investigation and research on the phenomenon that the packaging exterior material of the stacked packaging material is damaged, the problem was found in the frictional resistance between the packaging exterior material of the packaging product and the contact part that comes into strong contact with this packaging exterior material when stacked. Assuming that there is a clue to the solution, the contact part of the packaged product was composed of various materials, and as a result of conducting an experiment on the relationship between the static friction coefficient μ of the various materials with the package exterior material and the damage situation of the package exterior material, The following results were obtained.

In this experiment, the contact portion of a package made of various materials was actually brought into strong contact with the package exterior material of another package in a state in which the package was stacked in a stack. It is.

From the experimental results, it is found that the Teflon tape having a static friction coefficient μ of 0.10 or less has no damage to the packaging outer material, and the packing paper or the polypropylene band having the coefficient μ is about 0.10 is partially damaged. It was found that felts and steel bands having the coefficient μ greatly exceeding 0.10 were all damaged. Based on this result, the static friction coefficient μ of the present invention was set to 0.10 or less.

The packaging exterior material used in this experiment was obtained by impregnating the kraft paper on the inside with a rust inhibitor and laminating a vinyl film on the outer surface for airtightness and waterproofing. Is the most easily damaged.
Therefore, because other packaging cladding materials are more durable, when using any other packaging cladding material, by applying the static friction coefficient μ revealed in the present invention,
Damage to the packaging exterior material can be reliably prevented.

That is, even if there is a displacement t (see FIG. 8) between the stacked packaged products, the upper packaged product descends while being in contact with one of the lower packaged products during hanging down. It is located at the center between the two lower packaging products. At this time, the coefficient of static friction μ of the contact portion between the upper packaging product and the lower packaging product in contact with each other is 0.10 or less. The upper packaged product slides over the lower packaged product and is centered between the two lower packaged products without damaging the package cladding.

As described above, according to the present invention, from the viewpoint of pursuing safety at the time of handling, it is a common sense that a contact portion of a stacked package with a contact partner is made hard to slip by increasing the coefficient of static friction μ. As a result of reconsidering the details of the handling by reversing this conventional wisdom with respect to the conventional technology that was in place, the contact between the contact part of the packaged product and the contact partner was within the range that does not hinder the handling safety. It made it easier to slip.
