Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a book cover.

[0002]

[Prior art]

 Since the front cover of a book consists of a front cover, a back cover, and a spine, even if the vertical and horizontal dimensions of the book are the same, the dimensions of the spine do not become the same due to the thickness of the book. For this reason, for example, if the thickness of a book increases even if the paper size is the same (for example, Japanese Industrial Standards A row 4th), the book cover of the same size cannot be covered, and the book cover of various sizes depends on the thickness. There was a problem that a cover had to be prepared. Japanese Utility Model Laid-Open Publication No. Hei 6-79566 discloses a book cover that solves the above-described problem, in which a front cover that covers the front cover of a book and a back cover that covers the back cover of the book are separately provided. There has been disclosed a device in which both covers are adhered to each other at a portion where the covers overlap each other after the cover is placed on the cover. According to the present invention, the difference in book thickness can be absorbed by the overlapping portion of the front cover and the back cover which are separately configured, and therefore, the present invention can be applied to books having different thicknesses.

[0003]

[Problems to be solved by the invention]

 However, the inventor of Japanese Utility Model Laid-Open Publication No. Hei 6-79566 has a disadvantage that the front cover and the back cover must be bonded to each other when the book cover is attached to the book. In addition, since bonding work is required when installing the cover, if the work is to be carried out in a factory or the like in advance, it will take time and effort for the person in charge at that place to work on the cover in other places. Time is a big issue.

Therefore, the present invention solves the above-mentioned drawbacks of the prior art, and can properly cover the book even if the thickness of the book changes, can be easily and easily attached to the book, and can be removed. The task is to provide a book cover that can be easily made.

[0005]

[Means for Solving the Problems]

 The book cover of the present invention that solves the above-mentioned problem is a book cover that covers from the front cover of the book through the spine to the back cover, and the front cover and the back cover are provided on one end side of the back surface of the main body sheet of the cover. Is provided, and a cover insertion band is provided in the middle of the back surface of the main body sheet to allow the other cover to be inserted, and the other end of the main body sheet is provided. On the other side, a portion beyond the other cover is bent to the back side of the cover and inserted into the cover insertion band, and a surplus bending portion is provided for locking, and the cover insertion band and the bending surplus are provided. The first feature is that a folding auxiliary means for facilitating the bending of the excessive portion for bending is provided in the main body sheet between the two. In the book cover of the present invention, in addition to the first feature, the folding assisting means is formed of a thin wire whose thickness is thinner than that of the other to facilitate bending, and a plurality of the thin wires are arranged at regular intervals. This is a second feature.
