BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book cover.

[0002]

2. Description of the Related Art In a conventional book cover, an adhesive layer is formed on the entire inner surface of a synthetic resin sheet such as vinyl chloride, and release paper is attached to the adhesive layer.

[0003]

In the above-mentioned conventional book cover, since the release paper is not provided with the linear strips which are a standard when the book cover is attached, the book cover must be attached by using intuition. In many cases, the center of the book is out of alignment or the edges of the book and the book cover are not parallel to each other, which makes it difficult to mount the book beautifully.

The adhesive layer of a conventional book cover has a
Since no means for venting air is provided, air will enter between the book and the book cover when the book cover is attached, and if the air does not escape properly, it will become bubbles and the part will swell or wrinkle. However, there was a problem that it was very unsightly.

The present invention is intended to provide a book cover aiming at solving the above-mentioned conventional problems.

[0006]

According to the present invention, an adhesive layer is formed over the entire upper surface of a synthetic resin sheet, and a large number of small adhesive ridges are provided over the entire upper surface of the adhesive layer. Then, the release paper is formed so as to be projected in parallel with each other, and a grid-like scale line is printed over the entire surface, and a spine-splitting piece having a constant width can be cut off by two cutting lines in the central portion. The above-mentioned problems were solved by adopting a means of sticking to the adhesive layer of the synthetic resin sheet.

[0007]

According to the present invention having the above-mentioned structure, the spine cover of a book is formed in a central portion after the back split piece of the synthetic resin sheet is cut along the grid-like scale line of the release paper while keeping the balance of the top, bottom, left and right. , And then cut the corner and the back-splitting part together with the book along the scale line. After that, the release paper is peeled off, and the synthetic resin sheet is attached to the front cover and the back cover while pushing air toward the edge portion side along the adhesive ridges.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. A synthetic resin sheet 1 such as a vinyl chloride sheet
The pressure-sensitive adhesive layer 2 is formed over the entire upper surface, and a large number of small-width pressure-sensitive adhesive ridges 3 are provided in parallel at intervals 4 over the entire upper surface of the pressure-sensitive adhesive layer 2. The width of the adhesive ridge 3 and the gap 4 is not particularly limited, but preferably the adhesive ridge 3
It is recommended that the width of 1 mm and the width of the space 4 be 0.5 mm.

On the other hand, a release paper 5 is stuck on the adhesive layer 2 and the adhesive ridge 3 of the synthetic resin sheet 1. The release paper 5 has grid-like scale lines 6 printed on the entire surface thereof, and a back split piece 7 having a constant width is provided at the center of the release paper 5 so as to be separable by two cutting lines 8. Has been formed.

Next, the operation of the embodiment of the present invention will be described. First, as shown in FIG. 5, the surface on which the grid-like scale lines 6 are printed is taken as the upper surface, and the back split piece 7 at the center is cut along two cutting lines 8, and the adhesive layer 2 and the adhesive protrusion of that portion are cut off. Expose Article 3. Next, as shown in FIG. 6, while visually checking the scale lines 6 on the adhesive layer 2 and the adhesive ridges 3 on which the back split pieces 7 are separated, the spine cover of the book B is taken along the scale lines 6. While pressing up and down and left and right, press and bond them together, and then, as shown in FIG. 7, cut the corner portion and the back split portion along book B along the scale line 6, and leave as shown in FIG. All the release paper 5 is peeled off. Then, as shown in FIG. 9, the synthetic resin sheet 1 is attached to the front cover and the back cover. At this time, the surface of the synthetic resin sheet 1 is moved in parallel along the pressure-sensitive adhesive ridges 3 so as to wipe a piece of cloth, for example, to remove the air accumulated between the synthetic resin sheet 1 and the book B. Finally, as shown in FIG. 10, it is bent and attached to the corner portion to complete.

In the mechanism for removing the air, the adhesive ridge 3 is first adhered to the front cover and the back cover of the book B, and the air stays in the space 4 portion. After that, for example, as described above, the cloth piece is moved along the adhesive ridge 3 so that the surface of the synthetic resin sheet 1 is wiped, and the air staying in the space 4 is pushed out to the end edge side. The front cover and back cover of book B are also closely adhered to the space 4 where the air is released.

[0012]

[Effects of the Invention] Since the present invention is as described above, the spine of the book is centered on the center of the synthetic resin sheet while balancing the top, bottom, left, and right according to the grid-like scale lines printed on the release paper. Since the parts can be adhered without shifting and the corners can be cut along the scale lines, the cutting work can be performed accurately, easily and easily. Since it can be attached to the front cover and the back cover while removing air, the book cover can be attached to the book very beautifully without bulging due to unsightly air bubbles or wrinkling.
