Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a cover that covers the cover of a book.

[Conventional technology]

Conventional book covers include those made of strong paper or plastic sheets.

Paper sheets cover the cover of the book and fold the periphery back to the back of the cover, and plastic sheet sheets form a flat bag at one end, insert the free end of one cover into this bag, and fold the other end. has a folding allowance and folds this folding allowance to the back side of the other cover.

[Problems to be solved by the invention] The paper book cover is extremely complicated to attach to the book.

Book covers made of plastic sheets have a flat bag at one end, making them easy to attach to books, but since the other end is simply folded back to the back of the cover, the folded part may slip and loosen during use. , making the book look bad.

This invention is an attempt to solve the above-mentioned problems, and its purpose is to provide a book cover that can be easily attached to a book and whose appearance will not deteriorate even after use.

[Means for solving the problem] In order to solve the above problem, this invention uses a flat cylindrical sheet as a material and has a length equal to the width of an open book plus a folding allowance. The width is the same as or slightly larger than the vertical width of the book, and one end of the sheet is sealed and closed, and a cut line is provided on the layer on one side near one end that spans the entire width in the width direction, and the folding margin on the other end is one side. The flat cylindrical sheet portion on the other end that remains after cutting off the side layer has a required small size.A cut line is provided on the layer on one side over the entire length in the width direction near one end, and a pressure sensitive sheet is provided at the free end on the one side of the folding allowance. The book cover is provided with an adhesive layer and covered with release paper.

[Effect]

Insert the free end of one cover of the book into the flat bag at one end of the book cover, then cross the other end over the other cover, and insert the free end of the other cover into the cut line near the other end. Furthermore, it is pulled out through the inside of the flat cylinder part toward the folding margin, and the folding margin part is folded back to the back side of the other cover, and the release paper at the free end is peeled off, and the exposed pressure-sensitive adhesive layer is overlaid on the opposing surface and fixed by adhesion. do.

〔Example〕

FIG. 1 shows an example of a book cover according to the present invention. This book cover 1 is made of a flat cylindrical sheet 2 made of synthetic resin, and its length is as shown in FIG. , 4b is equal to the width when opened, plus a folding allowance 5.

Further, the width of the flat cylindrical sheet 2 is set to be equal to the vertical width of the target book.

In the case where the flat cylindrical sheet 2 has the length and width dimensions as described above, one end a of the cylindrical sheet 2 is closed by sealing or fusing, and a layer 6a on one side has a total length in the width direction at a position near the one end. A cut line 7a is formed extending over the cut line 7a, and one end side from the cut line 7a forms a bag portion 8.

The folding allowance 5 portion on the other end side of the cylindrical sheet 2 is made by cutting out the layer on one side, leaving only the layer 6b on the other side, and the cylindrical sheet portion on the other end side is a few centimeters from the end toward the one end side. The band 9 is formed by making incision lines 7b extending over the entire length in the width direction on the layer 6a on one side.

Further, a layer 10 of pressure sensitive adhesive is provided on one side of the free end of the folding margin 5, and this layer is covered with a release paper 11.

This book cover 1 is made by placing the book 3 on top of it in an open state as shown in FIG. 2, with the surface on which the notches 7a and 7b are formed facing up, as shown in FIG. Insert the end into the notch 7a,
By inserting the free end of the other cover 4b into the cut line 7b, the free end of the one cover 4a enters into the bag portion 8, and the other cover 4b is sandwiched between the other surface layer 6b and the band 9. Become.

Finally, the folding margin 5 is folded back to the back side of the other cover 4b, and the free end of the folding margin 5 is adhesively fixed to the surface of the band 9 using the pressure-sensitive adhesive layer 10 exposed by peeling off the release paper 11.

〔effect〕

The book cover of this invention has the following effects.

(1) This book cover has a bag part at one end into which the free end of one cover of the book is inserted, and the part that connects the folding margin on the other end has a bag part that overlaps the back side of the other cover. Since the cover is provided with a band that sandwiches the cover as a layer, there is no fear that the cover will shift in the width direction of the cover when it is placed over the book.

(2) Since the folding margin at the other end of the cover is folded back to the back side of the cover and adhered to the band, there is no risk of the cover coming off while the book is being handled while the cover is placed over the book.

(3) At the free end of the folding margin, a layer of pressure sensitive adhesive is formed on the surface facing the band with the folding margin folded back onto the band, and this adhesive layer is covered with release paper. The presence of the adhesive does not pose any problem during the folding operation of the folding margin.
