Is wound. The box material 13 shown in FIG.
Each corner protector 14a, 14b, 14c, 14d
Are mounted in the horizontal direction, but may be mounted in the vertical direction.

Each of the corner protectors shown in FIGS. 2 and 3 (a) has a weight at both ends of the corner protector when the corner protector is applied to the corner of the packaged object (cylindrical winding material 10 or box material 13). Although it is formed with a length that does not become too small, as in the present invention, if an adhesive layer is formed on the entire surface of the corner protector applied to the package, the band 12 is wound by pressing the corner protector. There is no necessity, and the corner protector can be appropriately attached to a corner portion of the packaged object by an adhesive layer.

In the present invention, as described above, the release layer is provided on the opposite surface of the contact surface of the corner protector. Hereinafter, a method of manufacturing a corner protector and a method of storing the same according to the present invention will be described.

As shown in FIG. 4A, the corner protector 15 according to the present invention is formed of a band-like, for example, cardboard material. The strip-shaped corrugated cardboard material has the same reinforcing plate 16 of corrugated cardboard material on both sides except for the central portion in the width direction.
16 is preferably formed by bonding.

The reinforcing plate 16 shown in FIG.
The central portion in the width direction where the reinforcing plates 16 are not joined is bent at a right angle along the broken line C in the direction in which the reinforcing plates 16 and 16 face each other and so that the cross section becomes L-shaped. Further, when it is desired to form the corner protector 15 into, for example, a ring shape, as shown in FIG. 5, a V-shaped notch A is further provided at one side at a constant pitch, and the corner protector 15 is used. At this time, it is embossed with a roll to form a ring.

An adhesive is applied or sprayed on the reinforcing plate 16 of the corner protector 15 shown in FIG. 5 to form an adhesive layer 17, and the reinforcing plate 16 on which the adhesive layer 17 is formed is formed.
The upper surface is the contact surface 15a side to the packaged object,
The release layer 18 is coated on the contact surface 15a and the reverse surface 15b with a release agent or by attaching a release paper.
Is provided.

The adhesive layer 17 and the release layer 18 may be formed when the corner protector 14 is not bent from the broken line C as shown in FIG. That is, as shown in FIG. 4A, after the reinforcing plate 16 is joined to the cardboard material forming the corner protector 14, the adhesive layer 17 is formed on the reinforcing plate 16, or the adhesive layer 17 is formed in advance. The reinforcing plate 16 may be joined to a cardboard material. At this time, as shown in FIG. 4B, which is the arrow B in FIG. 4A, the release layer 18 is formed on the opposite surface 15b of the surface 15a to which the reinforcing plate 16 is joined.
As shown in FIG. 5, the adhesive layer 17 and the release layer 18 may be formed in a state where the corner protector 15 is bent.

As a method of storing the corner protector 15 thus formed, as shown in FIG. 5, the corner protector 15 shown in the upper part of the drawing has the surface on which the adhesive layer 17 is formed and the lower part shown in the drawing. If the surface on which the release layer 18 of the corner protector 15 is formed is abutted and overlapped, the adhesive layer 17 formed on one corner protector 15 is separated by the release layer 18 into the other corner protector. Therefore, according to the present invention, it is possible to store a plurality of corner protectors 15 in an overlapping manner without bonding the corner protectors 15 to each other.

When the corner protector 15 is removed from the state where a plurality of the corner protectors 15 are removed from each other, the release paper (release layer 18) adhered to the other corner protector 15 by the adhesive force of the adhesive layer 17 of the one corner protector 15. It may be detached from the other corner protector 15 in a state of being attached to the adhesive layer 17, or may not be detached.

In the present invention, like the corner protector 3a shown in FIG. 6, when it is mounted on the corner of the cylindrical winding material 1 (packaged body), it is formed so that both ends overlap. Even if it is a corner protector, if an adhesive layer is formed on the contact surface of the corner protector and a release layer is formed on the opposite surface of the contact surface, it can be properly mounted and stored on the packaged object. Is possible.

In the present invention, the cylindrical wrapping material 10 or the box material 13 has been described as an example of the wrapped body, but the present invention can be applied to wrapped bodies having other shapes. For example, as shown in FIG.
a box material 20 having a corner protector 21 inside the inner space 20a.

[0030]

According to the present invention described in detail above, when a packing material is mounted on a corner of a packaged object, an adhesive layer is formed on a contact surface of the packing material, thereby suppressing the packing material. The packaging material does not need to be attached, and the packaging material can be appropriately affixed to the corner of the packaged object. In the present invention, a release layer is formed on the opposite surface of the contact surface on which the adhesive layer is formed. By doing so, when storing a plurality of the packing materials in a stack, the surface of the one of the packing materials on which the adhesive layer is formed and the surface of the other of the packing materials on which the release layer is formed are abutted against each other. When a plurality of the packing materials are overlapped, the packing materials are not bonded to each other.
