JP 2005-262893 A

However, since the book cover described in Patent Document 1 requires welding, the structure of the book cover is complicated, and the assembly of the book cover is troublesome. Further, the cost of the book cover increases with the welding process.
The present invention has been completed based on the above circumstances, and an object of the present invention is to simplify the structure of the book cover to facilitate assembly and to provide an inexpensive book cover.

  The present invention is a book cover provided with insertion pockets for holding the left and right ends of a book cover in an inserted state at both left and right ends of a cover main body that covers the front side of the book cover. A backing flap that is the same width as the main body, extends in the left-right direction, is bent at the boundary with the cover body, and is directed to the back side of the cover, and extends from the left and right outer portions of the upper and lower edges of the backing flap in the vertical direction The insertion flap that is inserted between the cover and the cover body while folding the backing flap, and the insertion slit formed by cutting the portion on the cover body side up and down from the insertion flap at the upper and lower end edges of the backing flap And extend vertically from the cover body, and when bent at the boundary with the cover body, Characterized in place and a vertical flap to be inserted in Tsu bets are configured.

  According to such a book cover, place the cover of the book on the back side of the cover body, fold the backing flap to the back side of the cover, insert the flap between the cover of the book and the cover body, The insertion pocket is completed by folding the upper and lower flaps to the back side of the cover while inserting the left and right outer portions into the insertion slit. In this way, the book cover can be assembled without performing processing such as welding or gluing, so that the assembly is easy. In addition, since the left and right ends of the cover of the book can be held in the insertion pocket, the book and book cover do not shift up and down. Furthermore, if you make the cover body translucent or opaque, you can prevent others from seeing the cover of the book you are reading. Therefore, the book cover can be easily assembled without complicated processing, and an inexpensive book cover can be provided.

The following configuration is preferable as an embodiment of the present invention.
The cover main body may include a transparent transparent window at a position corresponding to the spine of the book, and the opaque window covering material attached to the back side of the transparent window may be configured to be removable.

  According to such a configuration, for example, when reading a book on a train, an opaque window covering material can be pasted on the back side of the transparent window. For example, when a book is stored in a bookshelf at home, the window cover can be removed so that the back cover of the book can be seen from the transparent window. Further, since the window covering material can be re-peeled, it can be used repeatedly, which is very economical.

The cover body and the insertion pocket may be formed by punching a sheet material including a synthetic resin, paper, cloth, nonwoven fabric, or a composite material formed by combining these materials. Good.
Specific examples of the composite material include the following.
-Laminate with paper and synthetic resin laminated (PP pasting, pouch, lamination, etc.)-Laminate with laminate of cloth or nonwoven fabric and synthetic resin-Resin impregnated material with paper, cloth or nonwoven fabric impregnated with synthetic resin According to the configuration, a sheet-like book cover before assembly can be easily formed by punching the sheet material by Thomson processing, for example.

In the cover body, the portion corresponding to the back cover of the book may be configured to be larger in the left-right direction than the portion corresponding to the cover of the book.
According to such a configuration, a book cover can be attached to a thick book. In other words, in the cover body corresponding to the back cover of the book, the folding line of the backing flap is not provided in advance, and the folding line can be set freely according to the thickness of the book, so it can handle thick books. it can. The same applies to a thin book, and the fold line can be freely set according to the thickness of the book.

It is good also as a structure by which R process is given to the corner | angular part of the part by the side of a main body cover and the up-and-down both ends edge of a backing flap among the both-sides edges which comprise an insertion slit.
According to such a configuration, since the R processing is performed, the corner portion is easily turned with a finger. If the corners of the insertion slit are turned in this way, the left and right outer portions of the upper and lower flaps can be easily inserted into the insertion slit.

  According to the present invention, it is possible to simplify the structure of the book cover to facilitate assembly and thus to provide an inexpensive book cover.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. FIG. 1 is a front view of the book cover 10 of the present embodiment as viewed from the back side (side facing the book cover) in the unfolded state. The book cover 10 includes insertion pockets 30 that hold the left and right ends of the book cover in an inserted state at both the left and right ends of the cover body 20 that covers the front side of the book cover. The front cover of the book has a well-known configuration that integrally includes a front cover, a back cover, and a back cover. The book cover 10 of the present embodiment is made of a thick transparent film material (an example of the “sheet material” of the present invention, and in the present embodiment, 0.2 mm thick polypropylene is adopted), This film material is formed by punching with a Thomson mold.

  An opaque print layer 22 is printed on the back surface of the cover body 20 except for the transparent window 21 that is transparent. The transparent window 21 has a substantially rectangular shape in the vertical direction, and is arranged corresponding to the spine of the book. For this reason, for example, when a book that has been read is stored in a bookshelf at home, the spine of the book can be confirmed even with the book cover 10 attached. In addition, although the cover main body 20 of this embodiment is made of a transparent film material, a translucent or opaque film material may be used. The window shape of the transparent window 21 is not limited to a substantially rectangular shape, and may be any shape.

  As shown in FIG. 2 or FIG. 3, a window covering material 40 can be attached to the back side of the transparent window 21. The window covering material 40 of the present embodiment is slightly larger than the transparent window 21 and is made of an opaque paper material. In addition, you may comprise the window covering material 40 with the opaque film material with thickness.

  A releasable pressure-sensitive adhesive layer is applied to an adhesive surface that is affixed to the back side of the transparent window 21 among both surfaces of the window covering material 40. In the state where the window covering material 40 is pasted on the back side of the transparent window 21, the back cover of the book cannot be confirmed from the outside. Therefore, for example, since there is no possibility of others seeing the spine of the book being read on the train, it is possible to read the book without worrying about the surroundings. Further, the window covering material 40 can be re-peeled as shown in FIG. 4 and can be used repeatedly, so that it is very economical.

  As shown in FIG. 1, the cover body 20 has a left side portion (a portion corresponding to the back cover of the book) 20L from the transparent window 21 about 6 mm in the left-right direction than a right side portion (portion corresponding to the cover of the book) 20R. It is said to be large. The right portion 20R is formed to be approximately the same size as the book cover. On the other hand, the left portion 20L is formed slightly larger in the left-right direction than the back cover of the book. The reason why the left portion 20L is formed slightly larger in this way is that the left and right dimensions of the spine cover differ depending on the type of book, and the position of the folding line R1 in the left portion 20L can be freely set according to the left and right dimensions of the spine cover. This is to make it possible to set to.

  Next, the structure of the insertion pocket 30 will be described. In the unfolded state of the book cover 10 shown in FIG. 1, the insertion pocket 30 has a pair of left and right backing flaps 31, four vertical and horizontal flaps 32, four vertical and horizontal insertion slits 33, and four vertical and horizontal insertion flaps. 34 etc. are comprised.

  The backing flap 31 has the same width as the cover body 20 and extends in the left-right direction. The backing flap 31 can be bent with the boundary with the cover body 20 as a folding line R1. When the backing flap 31 is folded along the folding line R1, the left and right ends of the book cover are sandwiched between the backing flap 31 and the cover body 20, and the book cover is restricted from moving outward in the left-right direction. The

  The upper and lower flaps 32 extend in the vertical direction from the left and right outer portions of the upper and lower end edges of the cover body 20. The upper and lower flaps 32 can be bent with the boundary with the cover body 20 as a folding line R2. When the upper and lower flaps 32 are bent at the folding line R2, the upper and lower ends of the book cover are sandwiched between the upper and lower flaps 32 and the cover body 20, and the book cover is restricted from moving in the vertical direction.

  The insertion flap 34 is extended in the up-down direction from the left-right direction outer side part in the up-and-down both ends edge of the backing flap 31. As shown in FIG. The insertion flap 34 can be bent with a boundary with the backing flap 31 as a folding line R3. The insertion flap 34 is configured to be inserted between the cover and the cover body 20 while bending the backing flap 31.

  The insertion slit 33 is formed by vertically cutting a portion closer to the cover body 20 than the insertion flap 34 at both upper and lower edges of the backing flap 31. Of the both side edges constituting the insertion slit 33, the corner portion 35 between the side edge on the cover body 20 side and the upper and lower end edges of the backing flap 31 is subjected to R processing.

  Each fold line R1, R2, R3 is pre-folded so that it can be easily folded.

  After the backing flap 31 is folded to the back side of the cover body 20 at the folding line R1, the upper and lower flaps 32 are folded to the back side of the cover body 20 at the folding line R2, so that the backing flap 31 and the cover body 20 overlap each other. Is formed. And the insertion slit 33 is arrange | positioned in this superposition | polymerization area | region. As a result, the left and right outer portions of the upper and lower flaps 32 are inserted into the back side of the backing flap 31 from the insertion slit 33. Note that the vertical dimension of the insertion slit 33 is substantially the same as or slightly larger than the vertical dimension of the upper and lower flaps 32.

  The present embodiment has the structure as described above. Next, a method for assembling the book cover 10 will be described with reference to FIGS. Prior to assembling the insertion pocket 30, when the transparent window 21 is hidden, the window covering material 40 is pasted on the back side of the transparent window 21 in advance. When it is desired to remove the window covering material 40 and use it, the window covering material 40 may be removed from the transparent window 21 prior to assembly of the insertion pocket 30.

  First, as shown in FIG. 5, the cover 50 of the book is directed to the back side of the cover body 20. Next, as shown in FIG. 6, the insertion flap 34 is folded at a substantially right angle with respect to the backing flap 31 at a folding line R <b> 3. Next, as shown in FIG. 7, the folding flap 34 is inserted between the cover body 20 and the cover 50 as shown in FIG. 8 while the backing flap 31 is bent to the back side of the cover 50 along the folding line R <b> 1. The state shown in FIG. In this state, since the insertion flap 34 is inserted between the cover main body 20 and the cover 50, the backing flap 31 is held in a state where it is addressed to the back side of the cover 50.

  When the backing flap 31 is bent to the back side of the cover 50 in the left portion 20L, the position of the fold line R1 is set in accordance with the left end portion of the book cover 50, and the fold line R1 is bent. In this way, the left and right dimensions of the cover body 20 and the left and right dimensions of the cover 50 can be made the same regardless of the thickness of the book (the left and right dimensions of the back cover).

  Next, as shown in FIG. 10, the left and right outer portions of the upper and lower flaps 32 are inserted from the insertion slit 33 to the back side of the backing flap 31 while turning up the corner 35 with a finger. Then, when the corner portion 35 is released, the corner portion 35 is elastically restored to the original state, and the backing flap 31 and the upper and lower flaps 32 are held in an overlapped state as shown in FIG.

  In this overlapping state, when the upper and lower flaps 32 are to be opened, the backing flap 31 is to be opened through the insertion slit 33. Here, since the backing flap 31 is assembled to the book cover 50 in a state of being hung from both the upper and lower sides by a pair of upper and lower insertion flaps 34, it acts in the direction of lifting the book cover 50. However, since the book itself has its own weight, the cover 50 of the book does not lift, and as a result, the opening of the backing flap 31 is restricted via the insertion flap 34 and the upper and lower flaps are restricted via the insertion slit 33. The opening of 32 is restricted.

  In this way, the insertion pocket 30 is completed, and the assembly of the book cover 10 is completed. Therefore, the left and right ends of the book cover 50 are held in the inserted state by the insertion pocket 30.

  As described above, in the present embodiment, the insertion flap 34 is inserted between the cover body 20 and the cover 50 while the backing flap 31 is bent, and the left and right outer portions of the upper and lower flaps 32 are inserted into the insertion slit 33. Since the insertion pocket 30 is configured, the insertion pocket 30 can be easily formed without any complicated processing such as welding or gluing, and the book cover 10 can be easily assembled.

  Further, since the book cover 10 has a sheet shape, the entire configuration can be simplified. Moreover, since it is sheet-like, the book cover 10 can be punched by Thomson processing or the like. Furthermore, since a thick film material is adopted as the material of the book cover 10, the durability can be improved and the book can be reliably protected.

  Further, since the portion corresponding to the back cover of the book in the cover body 20 is formed larger than the portion corresponding to the cover, the position of the fold line R1 of the left portion 20L can be freely set corresponding to a thick book or a thin book. can do.

  Further, since the cover body 20 is provided with a transparent window 21 and a window covering material 40 covering the transparent window 21 can be pasted, the window covering material 40 is used when the title of the back cover is not to be seen by others. The window covering material 40 can also be peeled off when it is desired to store it in a bookshelf at home so that the back cover can be confirmed. Moreover, since the adhesive layer which can be peeled again was employ | adopted for the window covering material 40, the window covering material 40 can be used repeatedly.
