Description

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

Conventionally, this type of book cover has been easily formed by folding paperboard and stapling the overlapped ends as appropriate, making it easy to break.Also, it lacks luxury and is not suitable for so-called luxury books. Both the quality and quantity of images were extremely unsuitable for books with large volumes.

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.

The present invention will be explained below by way of an embodiment with reference to the drawings.

The one shown in Figure 1 is a box-shaped book cover with only one side open, and its front and back plates 1 and 2 and top and bottom side plates 3 and 4 have the structure shown in Figures 2 and 3. It is formed.

That is, as shown in FIG. 2, a rectangular cardboard 6 is pasted on one side with a covering paper 5 having a suitable decoration such as lacquer-like or leather-like decoration, and long sides 7, 7 are attached on the other side. W-shaped grooves 9, 9 are formed along the longitudinal direction at a distance 1 equal to 1/4 of the length of the shorter sides 8, 8, and both sides formed by the W-shaped grooves 9, 9 are formed. 10 and 10 are respectively folded inward from the W-shaped groove 9° 9 and joined so that the long sides 7, 7 butt each other as shown in FIG. 3 to form a two-ply structure.

Next, this is adjusted to the length of the front and back plates 1.2 and the top and bottom side plates 3, 4, as shown in FIG. 3, with the V-shaped groove 11.
12. 13 are formed at intervals, and the shorter sides 8, 8 at both ends form cutout surfaces 14 and 15 inclined at 45 degrees, respectively.

In addition, a concave groove 16 is formed along the longitudinal direction a little further inside than one of the longitudinal sides 7.

Then, the member is shaped like a ■ so that the four edges of the rectangular back plate 17 fit into the concave groove 16.
The book shown in FIG. 1 and FIG. A cover is formed.

The back plate 17 is made of rectangular cardboard with a cover paper 5 pasted on one side in the same manner as the side plates.

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, so there are no seams or differences in the outer surface of the cover due to overlapping. , it is possible to provide something that is extremely beautiful and has a luxurious feel.

In addition, because it is made up of two layers of cardboard with a cover pasted on the surface, it does not warp and can always be stored in a perfect fit with the book, which helps protect the book's shape. This is preferable.

Furthermore, since the back plate is recessed from the outer periphery of each side plate, it is difficult to peel off when a piece of paper indicating the name of a book is pasted.
It also has the advantage of being resistant to stains.

Claims (1)

[Scope of utility model registration request] A box-shaped book cover with one side open, covered with one side of cardboard with the same length as the entire circumference of the front and back panels and the top and bottom side panels, and twice the depth and width of each side panel. At the same time as pasting the paper, W-shaped grooves are formed in parallel in the longitudinal direction on the other side of the cardboard at intervals of the same width as the depth of each side plate, and these are placed between the two sides so that the cover paper is on the front side. Fold inward from the W-shaped groove and join the edges to make two layers,
Furthermore, a concave groove is formed near the longitudinal and lateral edges of the folding surface, and three V-shaped grooves forming each side plate are formed at a predetermined interval in the lateral direction. Bend each of the rectangular backboards at right angles from the ■-shaped grooves so that the peripheral edges of the rectangular backboard fit into the concave grooves to surround the backboard, and then bend both ends of the folded cardboard at a 45 degree angle. A book cover made of cut-out surfaces and glued together.
