Description

  The present invention relates to a cover member forming a hard cover book.

In general, as shown in FIGS. 6 and 7, the cover member of a hard cover book or the cover member of an album has a cardboard 12 as a core material and an adhesive 11 is applied to the upper surface of the cardboard 12, and glossy paper 14 Is pasted. Then, the edge 14a of the glossy paper is folded at the end 12a of the cardboard, and the edge 14a of the glossy paper that is folded back is adhered to the lower surface of the cardboard 12.
Such a cover member 10 may be warped after a while, and the appearance may be impaired.

On the other hand, a cover member 10 is disclosed that hardly warps even when time passes (see, for example, Patent Document 1).
Utility Model Registration No. 2538747

  This cover member 10 pays attention to the “paper eyes” generated in the direction in which the paper fibers flow during paper making, and when the two paper materials are pasted, the paper eyes are orthogonal to each other. Measures against warping.

However, even if such a cover member 10 is not warped, the surface of the cardboard 12 originally has fine irregularities. Therefore, the glossy paper 14 affixed to the cardboard 12 also has irregularities along the irregularities, and the glossy paper 14 is not completely flat.
Therefore, the cover member 10 still has a problem that the image reflected on the glossy paper 14 that is the appearance is distorted. In the case of the cover member 10 used for a normal book, this degree of distortion of the surface of the cover member 10 is not a problem. For example, in the case of a cover member 10 used as a commemorative album or a match photo Since a high-class feeling is required, the surface of the cover member 10 is desirably a mirror surface without distortion.

  Accordingly, an object of the present invention is to provide a cover member in which glossy paper on the surface becomes a mirror surface with less distortion even when cardboard is used as a core material.

  In order to achieve the above object, a cover member (20) according to claim 1 of the present invention is a cover member (20) that forms a book of a hard cover, and an adhesive (11) is applied to the upper surface of the cover member (20). Cardboard (12) as a material, smooth paper (23) stuck on the upper surface of the cardboard (12), and stuck on the upper surface of the smooth paper (23), the edge (14a) Glossy paper (14) which is folded at the end (12a, 23a) of the smooth paper, the folded edge (14a) is adhered to the lower surface of the cardboard (12), and has gloss on the upper surface. It is characterized by comprising.

  Further, the cover member (20) according to claim 2 is characterized in that a plurality of adhesives (11) are applied in the form of dots on the upper surface of the cardboard (12).

  Further, the cover member (20) according to claim 3 is such that the adhesive (11) has a substantially equal diameter (D) and a distance (S) between the respective adhesives is substantially equal. It is characterized by being applied to.

  The cover member (20) according to claim 4 is characterized in that an adhesive (11) is applied on the upper surface of the cardboard (12) in a lattice pattern.

  The cover member (20) according to claim 5 is characterized in that the cardboard (12) forms a front cover and a back cover of a book.

  Further, the cover member (20) according to claim 6 is characterized in that the upper surface of the smooth paper (23) is tucked.

  Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

  According to the cover member of claim 1 of the present invention, in the cover member that forms the book of the hard cover, the cover member has smooth paper stuck on the upper surface of the cardboard, and glossy paper on the upper surface of the smooth paper. Since it is stuck, the surface of the glossy paper is flat. That is, even if the surface of the cardboard is uneven, smooth paper is interposed between the cardboard and the glossy paper, so that the influence of the cardboard unevenness on the glossy paper is reduced. Therefore, the image reflected on the glossy paper is hardly distorted and has a high-class feeling.

  Moreover, according to the cover member of Claim 2, in addition to the effect of the invention of Claim 1, since a plurality of adhesives are applied to the upper surface of the cardboard in the form of dots, it is adhered to the upper surface. Smooth paper is flat. That is, even if the surface of the cardboard is uneven, the cardboard and the smooth paper are only partially in contact with each other, so that the smooth paper is hardly affected by the surface unevenness of the cardboard. Therefore, the smooth paper is flat, and the glossy paper stuck on the upper surface thereof is flatter along the smooth paper, so that the image reflected on the glossy paper is hardly distorted.

  Further, according to the cover member of claim 3, in addition to the function and effect of the invention of claim 2, the adhesives have substantially the same diameter, and the distances between the adhesives become substantially the same. Since the adhesive spreads when the smooth paper is applied to the cardboard, the adjacent adhesives are not joined to each other. Therefore, since the bonding area between the cardboard and the smooth paper does not increase, the flatness of the glossy paper is guaranteed.

  Moreover, according to the cover member of Claim 4, in addition to the effect of the invention of Claim 1, since a plurality of adhesives are applied on the upper surface of the cardboard in a lattice shape, it is stuck on the upper surface. Smooth paper is flat. That is, even if the surface of the cardboard is uneven, the cardboard and the smooth paper are only partially in contact with each other, so that the smooth paper is hardly affected by the surface unevenness of the cardboard. Therefore, the smooth paper is flat, and the glossy paper stuck on the upper surface thereof is flatter along the smooth paper, so that the image reflected on the glossy paper is hardly distorted.

  Further, according to the cover member of claim 5, in addition to the function and effect of the invention of claims 1 to 4, the cardboard forms the front cover and the back cover of the book, so the cost can be reduced. . In other words, only the front cover and the back cover that are flat are formed, and the cross-section arc shape is often used originally, and the back cover portion that is not flat is not used for the cover member having such a structure. There is no cost.

Further, according to the cover member of the sixth aspect, in addition to the function and effect of the inventions of the first to fifth aspects, the upper surface of the smooth paper is tucked so that the glossy paper is smoothed by the thickness of the tack glue. The degree increases. That is, since the thickness of the tack paste reduces the influence of the irregularities of the cardboard on the glossy paper, the image reflected on the glossy paper is more difficult to distort.
Moreover, the sticking operation is simplified.

  In addition, like the cover member of the present invention, the point obtained by applying a smooth paper after applying an adhesive to the upper surface of the cardboard in a dot or lattice form is completely described in Patent Document 1 described above. Not.

  A cover member 20 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 is an exploded plan view showing a cover member 20 according to an embodiment of the present invention. FIG. 2 is a perspective view of the cover member 20 shown in FIG.

  The cover member 20 forms a hard cover book, and includes a cardboard 12, a smooth paper 23, and a glossy paper 14.

The cardboard 12 becomes a core material in the cover member 20. Further, as shown in FIGS. 1 and 2, the cardboard 12 is divided into those forming a front cover, a back cover, and a spine of a book.
Here, the adhesive 11 is formed on the upper surface of the cardboard 12 forming the front cover and the back cover of the book so that the diameters D are substantially equal and the distances S between the respective adhesives are substantially equal. A plurality of coatings are applied. Specifically, as shown in FIG. 3, the diameter D of the adhesive was about 10 mm, and the distance S between adjacent adhesives was about 50 mm.
On the other hand, the top surface of the cardboard 12 forming the spine is subjected to a tacking process.

The smooth paper 23 is a paper having a smooth surface, the upper surface of which is tacked, and the lower surface remains a normal paper material. This tacking process is a so-called sealing process, and the smooth paper 23 is composed of a base material, tack glue, and release paper in order from the lower layer side. When sticking to an object, peel off the release paper before use. In this embodiment, it is assumed that the release paper is peeled off in advance.
The smooth paper 23 is attached to the upper surface of the cardboard 12 and the portion of the cardboard 12 that forms the front cover and the back cover of the book. That is, the smooth paper 23 is not attached to the cardboard 12 forming the spine of the book.

The glossy paper 14 is glossy paper on the upper surface, and as shown in FIG. 1, the outer shape is one size larger than a set (three sheets) of cardboard 12 placed side by side. The lower surface of the glossy paper 14 that forms the front cover and the back cover of the book is attached to the upper surface of the smooth paper 23, and the lower surface of the glossy paper 14 that forms the back cover of the book is the surface of the cardboard 12. Affixed to the top surface. Then, the edge 14 a of glossy paper is folded back at the end portions 12 a and 23 a of cardboard and smooth paper, and the folded edge 14 a is attached to the lower surface of the cardboard 12.
That is, the cover member 20 has a three-layer structure of the cardboard 12, the smooth paper 23, and the glossy paper 14 at the portion where the front cover and the back cover of the book are formed as shown in FIG. In FIG. 4, the papers 12, 23, and 14 are drawn apart from each other for easy understanding, but in reality, they are pasted as described above.

According to the cover member 20 configured as described above, a plurality of adhesives 11 are applied to the upper surface of the cardboard 12 in the form of dots in the cover member 20 that forms a hard cover book and has the cardboard 12 as a core material. Therefore, the smooth paper 23 stuck on the upper surface becomes a flat surface. That is, even if the surface of the cardboard 12 is uneven, the cardboard 12 and the smooth paper 23 are only partially in contact with each other, so that the smooth paper 23 is not easily affected by the unevenness of the cardboard 12. Therefore, the smooth paper 23 is flat, and the glossy paper 14 adhered to the upper surface thereof is flat along the smooth paper 23, so that the image reflected on the glossy paper 14 is difficult to be distorted and has a high-class feeling.
Further, since the adhesives 11 are applied in the form of dots so that the diameters D are approximately equal and the distances S between the adhesives are approximately equal, when the smooth paper 23 is adhered to the cardboard 12 Even if the adhesive 11 spreads, the adjacent adhesives 11 are not joined. Therefore, since the bonding area between the cardboard 12 and the smooth paper 23 does not increase, the flatness of the glossy paper 14 is guaranteed.

In addition, since the smooth paper 23 is attached to the portion of the cardboard 12 that forms the front cover and the back cover of the book, the cost can be reduced. That is, since the cross-section arc shape is often used and the smooth paper 23 is not used for the spine portion that is not flat, the cost is not increased accordingly.
In addition, since the upper surface of the smooth paper 23 is tucked, the smoothness of the glossy paper 14 is increased by the thickness of the tack glue, and the image reflected on the glossy paper 14 is more difficult to distort. Moreover, the sticking operation is simple.

  The adhesive 11 applied to the upper surface of the cardboard 12 forming the front cover and back cover of the book is applied in the form of dots so that the diameters D are approximately equal and the distances S between the adhesives are approximately equal. However, the present invention is not limited to this, and the diameters D may not be approximately equal, and the distances S between the respective adhesives may not be approximately equal. That is, if the cardboard 12 and the smooth paper 23 are partially attached, the distortion of the image shown on the glossy paper 14 can be sufficiently reduced.

  Further, the adhesive 11 is applied in the form of dots, but the present invention is not limited to this, and the adhesive 11 is applied in a lattice shape parallel to each side of the cardboard 12 as shown in FIG. Alternatively, as shown in FIG. 5 (b), the adhesive 11 may be applied in a lattice shape inclined by 45 degrees with respect to each side of the cardboard 12.

  Further, the adhesive 11 may be applied to the entire upper surface of the cardboard 12. That is, even if the surface of the cardboard 12 is uneven, since the smooth paper 23 is interposed between the cardboard 12 and the glossy paper 14, the influence of the unevenness of the cardboard 12 on the glossy paper 14 is reduced and glossy. The image shown on the paper 14 is less distorted than before.

  Further, the smooth paper 23 is attached only to the portion of the cardboard 12 that forms the front cover and the back cover. However, the present invention is not limited to this, and the portion of the cardboard 12 that forms the back cover is also smooth. Paper 23 may be attached.

Moreover, although the cover member 20 which integrally forms a front cover, a back cover, and a back cover was described, it is not restricted to this, You may form a front cover and a back cover independently, respectively. That is, in an album or the like that does not have a spine cover, a smooth paper 23 having the same size as that of the cardboard 12 is attached to the upper surface of the cardboard 12, and the glossy paper 14 is attached from the upper surface to attach the cover member 20. It may be formed.
Further, the cardboard 12 is divided into three sheets forming a front cover, a back cover, and a back cover of the book. However, the present invention is not limited to this, and one ball smaller than the glossy paper 14 is used. It may consist of paper 12.

Moreover, although the upper surface of the smooth paper 23 has been tacked, the present invention is not limited to this, and the smooth paper 23 and the glossy paper 14 may be attached by gluing. And this gluing may be by glue.
Further, although the adhesive 11 is applied to the upper surface of the cardboard 12, the adhesive 11 is not limited to the adhesive 11 and may be a glue or a small double-sided tape.

  Moreover, although the diameter D of the adhesive apply | coated to the dotted | punctate form and the distance S between adhesives showed the optimal thing, it is not limited to this numerical value.
