Description

[Detailed Description of the Invention] The present invention relates to a box-shaped book cover for covering a book.

In the past, this type of book cover was generally made by folding paperboard and stapling the overlapping edges as appropriate, making it easy to break and lacking in luxury, giving rise to the so-called deluxe book cover. Both quality and quantity were extremely unsuitable for a book with a large volume.

Therefore, the present invention was devised to provide a book cover that is made of paper but has the luxury and beauty suitable for use as a so-called deluxe book, is robust, and is inexpensive to produce.

Embodiments of the present invention will be described below with reference to the drawings.

What is shown in FIG. 1 is a box-shaped book cover with only one side open, and its front and back panels 1.2 and top and bottom side panels 3, 4 have the structure shown in FIGS. 3 to 5, for example. is formed.

That is, as shown in FIG. 3, a rectangular cardboard 6 is pasted on one side with a covering paper 5 having an appropriate decoration such as lacquer-like texture, various kinds of leather textures, old Japanese paper texture, etc. A W-shaped groove 7 is formed in the center of the longitudinal direction, and the layers are folded at the W-shaped groove 7 and bonded to each other at the joint surfaces to form a two-layered structure as shown in Fig. 4. A stepped portion 8 is formed by cutting leaving only the cover paper 5 on the outer surface at the edge, and the front and back plates 1 and 2 and the top and bottom side plates 3 and 4 are placed on the side where the stepped portion 8 is provided, that is, on the inner surface. As shown in Fig. 5, V-shaped grooves 9, 10, 11 are formed at intervals in the transverse direction according to the length, and notches inclined at 45 degrees are formed on the transverse sides 12 and 12 of both ends. Form surfaces 13.14.

Then, two-layered cardboard is inserted into the ■-shaped grooves 9 and 1 so that the edges of the four sides of the rectangular back plate 15 fit into the stepped portion 8.
0 and 11 to surround and attach the back plate 15, and the opposing shorter sides 12 and 12.
By attaching the cutout surfaces 13, 14 at both ends, a book cover as shown in FIGS. 1 and 6 is formed.

The back plate 15 is made of rectangular cardboard with a cover paper 5 pasted on one side in the same manner as the side plates.

Further, FIGS. 7 and 8 show other embodiments in which the front and back plates 1 and 2 and the top and bottom side plates 3 and 4 are formed,
In this embodiment, W-shaped grooves 7, 7 are formed on the other side of the rectangular cardboard 6 to which the cover sheet 5 is pasted, at a distance 1 of 172 from the long side 16.16 to the short side 12.12. It is formed along the longitudinal direction, and the two side parts 17 and 17 are folded inward and the joint surfaces are glued so that the long sides 16 and 16 are butted together as shown in Fig. 8 to form a two-layered structure. As in the previous embodiment, a stepped portion 8 is formed on one side edge of the long side 16 by leaving the cover paper 5 on the outside surface, and a square part is formed in the width direction of the inside surface. The grooves 9, 10, 11 are formed at intervals, and the shorter sides 12, 12 at both ends are each 45 mm.
Form the cutout surfaces 13 and 14 that are slanted at the same angle, and then bend them from the V-shaped grooves 9, 10, and 11 in the same manner as in the previous embodiment, and fit the four edges of the back plate 15 with the stepped portions 8 to attach it. This forms the book cover.

As mentioned above, the book cover of the present invention has a two-layer structure with the front and back sides as well as the top and bottom side panels with the cover paper on the outside surface, and the outer surface of the cover including the back panel has seams and overlaps. There are no steps and it looks good, and it also has a nice appearance.

Furthermore, the decorative effect of the cover paper makes it extremely beautiful and luxurious.

In addition, since the cover is pasted on the surface of cardboard and is made of two layers, it does not warp and always fits perfectly to the shape of the book, which helps protect the book's shape. This can be achieved by bringing about good results.
