Description

[Detailed Description of the Invention] This invention relates to a tack for preventing cargo from collapsing, and more particularly to a member used to prevent cargo from collapsing when stacking packaging cases and the like.

Conventionally, when storing or transporting packaging cases such as cardboard cases stacked high, they are lashed with ropes or bands, or wrapped with sheet covers to prevent them from collapsing. is being carried out, but
All of them had the disadvantage that the larger the stacked volume of the packaging cases, the more difficult the work was, and that it was impossible to take out the packaging cases for each item.

On the other hand, such a laminate may be fixed from the side with an adhesive tape or the like, but this has the disadvantage that the surface of the packaging case may be broken when the adhesive tape is peeled off and removed, causing inconvenience.

This invention was devised in view of the above-mentioned drawbacks, with the purpose of providing a tack for preventing cargo from collapsing, which can be easily prevented from collapsing, and also allows the removal of packaging cases for individual items as needed. A large number of double-sided adhesive sheet pieces, which are formed by providing adhesive layers on the front and back sides of a sheet body with low interlaminar strength in the direction, are laminated with release paper having different peelability on the front and back sides,
Further, the release paper is characterized in that it extends outward from the edge of the double-sided adhesive sheet piece.

This invention will be explained below using examples.

FIG. 1 is a sectional view of an embodiment of this invention, and FIG. 2 is a perspective view of the embodiment.

The trick A for preventing load collapse according to this invention is that a double-sided adhesive sheet piece 1 is formed by providing adhesive layers 1B and 1B on the front and back sides of a sheet body 1A with low interlayer strength in the thickness direction, for example, a non-woven fabric sheet body. A large number of sheets of release paper 2 are laminated with each other having a peelability on the front side 2A that is easier to peel than on the back side 2B, and the release paper 2 is a piece of double-sided adhesive sheet. 1 and extends outward from the edge 1' of 1.

It should be noted that in the illustrations of the above embodiments, the thickness of each layer is exaggerated for illustrative purposes, and in reality, the thickness of the sheet piece 1 and the release paper 2 are the same as those normally used. There is almost no difference.

To use this devised trick A for preventing cargo from collapsing, first, as shown in FIG. Next, as shown in FIG. 3, this peeled double-sided adhesive sheet piece 1 is adhered to the top surface 4A of a packaging case 4 such as a cardboard box to be stacked with the release paper 2 supported, and then the release paper 2 is peeled off. A packaging case 4 such as an upper layer of cardboard boxes is placed thereon.

In the above, when the double-sided adhesive sheet piece 1 is peeled off from the laminate, each piece of the double-sided adhesive sheet piece 1 is easily peeled off because the adhesive strength of the release paper is different on the front and back sides.

When the packaging cases 4 are stacked, they are adhered to each other by the double-sided adhesive tack A, and even if a force as shown by the arrow p in FIG. 4 is applied, the packaging cases 4 will not shift laterally or collapse.

Next, when removing the packaging case 4 from the stacked state, lift the upper packaging case 4 as shown in FIG. It is easily broken and separated in the thickness direction.

Therefore, there is no risk of breaking the surface layer of the cardboard case or the like, unlike when adhesive tape is peeled off.

This idea is structured as above, so
When stacking packaging cases in multiple stages, the packaging cases are adhered to each other with pieces of adhesive tape, which reliably prevents relative displacement in the lateral direction, effectively preventing the cargo from collapsing, and making it easier to remove the cargo. Since the base sheet of the double-sided adhesive sheet can be easily divided in the thickness direction, each product can be taken out without damaging the surface layer of the packaging case.

In addition, the structure of this devised tack for preventing cargo collapse is simple, so it can be provided at low cost, and since a part of the release paper extends outward from the double-sided adhesive sheet, it is easy to perform the peeling operation. It has practical effects.
