Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a package for a cylindrical article such as a web for printing, for example.

(Prior Art) Conventionally, in the case of packing bodies for cylindrical articles such as paper rolls for printing, as shown in FIGS. Place paper on both ends of the cylindrical article, wrap it in a sushi roll shape with an outer circumferential surface protective material with a width slightly wider than the width of the cylindrical article, and use adhesive to prevent it from unraveling. The protruding part was folded into the end face side, and an end face protection material was adhered to this part with adhesive.

(Problem to be solved by the invention) When unpacking such a conventional package for a cylindrical article, a cutter is inserted between the protective member on the end surface side and the end surface of the cylindrical article. Because it is necessary to cut with a cutting tool such as, not only great care is required, but sometimes the cylindrical article that is the contents may be damaged.

The present invention was devised in view of the above points, and its purpose is to prevent damage to the cylindrical article, which is the contents, at the end surface side portion of the protective material that covers the cylindrical article. It is easy to cut and unveil.

(Means for Solving the Problems) In order to achieve the above object, the present invention uses a disc-shaped backing material having grooves on its outer circumferential surface over the entire circumference. We are trying to resolve the issues.

That is, in the present invention, the outer diameter of both end surfaces of the cylindrical article is approximately the same as the outer diameter of the cylindrical article,
A disk-shaped backing material having a groove is brought into contact with the outer circumferential surface thereof all around in the circumferential direction, and these are covered with an outer circumferential surface protection material and an end surface protection material.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A groove is formed on both end surfaces 2, 2 of a cylindrical article a having a paper tube 1 in the center, the outer diameter of which is approximately the same as the outer diameter of the cylindrical article a, and which guides a cutting tool 3 such as a cutter on the outer peripheral surface. 4 is provided around the circumference, and disk-shaped backing members b, b having a large through hole 5 in the center are brought into contact with each other.

In this case, the disc-shaped backing member b may be made of three pieces of cardboard pasted together, a plastic molded product, or the like.

With the backing materials b, b in contact with both end surfaces 2, 2 of the cylindrical article a, these are wound into a sushi roll shape with the outer peripheral surface protective material c, which is slightly wider than these widths, and the ends 6 of the cylindrical article a are rolled. Glue them so that they overlap to some extent.

Next, the protruding portions of the outer circumferential surface protection material c are folded into the side surfaces of the backing materials b, b, and the end surface protection materials d, d are adhered to the folded portions 7, 7 with adhesive, thereby forming a package A of cylindrical articles. Configure.

To unpack the package A as described above, use a cutting tool 3 such as a cutter to cut into the circumferential grooves 4, 4 extending all around the padding materials b, b on both ends of the package A. While rolling the package A using the groove 4 as a guide, the outer circumferential surface protection material c is cut along the groove 4.

Next, after removing the backing materials b, b, the outer circumferential surface protection material c is peeled off from the adhesive portion at its end 6 and opened.

(Effect of the invention) The present invention is a cylindrical article in which a disc-shaped backing material having an outer diameter approximately the same as the outer diameter and having a circumferential groove on the outer peripheral surface is brought into contact with both outer ends of the cylindrical article. is covered with an outer peripheral surface protection material and an end surface protection material,
The end surface side of the cylindrical article that is the contents can be sufficiently protected by the padding material, and even when unpacking, the cutting tool such as a cutter is guided by the circumferential groove of the padding material. , the cylindrical article is not damaged at all and can be opened easily.
