Description

[Technical field]

[0001] The present invention relates to a paper product suitable for use in stamp books, writing books, scriptures, etc. In particular, the present invention relates to a paper product that includes a folded-book format of paper that is folded into multiple sheets and a cover that sandwiches and binds the paper, and that allows the paper to be replaced and is easy to handle. [Background technology]

[0002] Conventionally, as described in Patent Document 1, for example, paper products such as stamp notebooks, writing books, and sutra books are known that are configured with a folded-book format paper (paper on which letters and figures are written) that is folded into multiple sheets and a cover that sandwiches and binds the paper.

[0003] FIG. 1 is a perspective view showing a schematic configuration of a conventional paper product having the above-mentioned structure. As shown in Fig. 1, a conventional paper craft 100' comprises a sheet 1 in a fold-out format in which the sheet is folded into multiple sheets, and a pair of covers 3, 4 that sandwich and bind the sheet 1. Although the characters and figures written on the sheet 1 are omitted in Fig. 1, if the paper craft 100' is a sutra book, the characters of the sutra are written on the sheet 1 in advance. Also, if the paper craft 100' is a writing book or a red seal book, lines and the like may be written in advance. One cover 3 is attached to the first page 12 of the sheet 1 by gluing or the like, and the other cover 4 is attached to the last page 13 of the sheet 1 by gluing or the like.

[0004] As described above, in the conventional paper product 100', the paper 1 is attached to the covers 3 and 4, which causes a problem that the paper 1 cannot be replaced (the covers 3 and 4 cannot be used for another paper 1). Furthermore, in the conventional paper product 100', the cover that sandwiches and binds the paper 1 is separate into a cover 3 for the first page 12 and a cover 4 for the last page 13. This means that, for example, when carrying the paper product 100' in a bag or the like, the folded paper 1 may open up by itself (as shown in Figure 1, the accordion-folded paper 1 is stretched out), or when using it, one of the covers 3 or 4 may inadvertently drop from the user's hand, causing the paper 1 to open up. This creates problems in that it is not easy to handle. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Utility Model Registration No. 3205791 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made to solve the problems of the above-mentioned conventional technology, and has an object to provide a paper product that includes a fold-out format of paper folded into multiple sheets and a cover that sandwiches and binds the paper, which allows the paper to be replaced and is easy to handle. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides a paper product comprising a folded-book format paper folded into multiple pages, and a cover that sandwiches and binds the paper, the cover being formed from a single sheet and having fold-in portions at both ends that are each folded inward along a crease, and the first and last pages of the paper are each inserted into the fold-in portions of the cover, thereby sandwiching and binding the paper between the cover.

[0008] The paper product of the present invention has a cover formed from a single sheet, and the first and last pages of a sheet of paper are inserted into the fold-in portions at both ends, thereby sandwiching the sheets of paper between the cover and binding them. In other words, the paper product according to the present invention is not configured in such a way that the paper is attached to the cover as in the conventional paper product, and therefore the paper can be replaced. In addition, since the paper product of the present invention does not have a separate cover as in the conventional paper products, it is possible to prevent the paper 1 from opening on its own or inadvertently, making it easy to handle.

[0009] In the paper product according to the present invention, it is preferable that the cover has a resin layer near the fold, the resin layer being coated with a resin having a higher coefficient of friction with respect to the paper than the cover.

[0010] In the above preferred configuration, the cover has a resin layer applied near the fold (the area where the edge of the first page and the edge of the last page of the paper inserted into the fold-in part folded inward along the fold can be located), where the resin has a higher coefficient of friction with the paper than the cover. This increases the frictional force generated between the resin layer and the first and last pages of the paper inserted into the fold-in part, making it difficult for the first and last pages of the paper, and ultimately the entire paper, to slip relative to the cover. Therefore, according to the above-described preferred configuration, while retaining the advantage of being able to replace the paper, the paper is less likely to shift relative to the cover, making the booklet even easier to handle. Effect of the Invention

[0011] According to the present invention, it is possible to provide a paper product that includes a folded booklet format of paper that is folded into multiple sheets and a cover that sandwiches and binds the paper, which allows the paper to be replaced and is easy to handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a paper product according to an embodiment of the present invention will be described with reference to the attached drawings. Note that the dimensions, scale, and shapes of the components shown in each drawing may differ from the actual ones. The paper product according to this embodiment is suitable for use as a stamp book, a writing book, a sutra book, and the like. FIG. 2 is a diagram showing a schematic configuration of the paper product 100 according to the present embodiment. FIG. 2(a) is a perspective view of the last page 13 and the penultimate page 1 of the paper product 100 in the state where they are open, FIG. 2(b) is a front view of the paper 1 in the state where it is completely folded, FIG. 2(c) is a side view of the paper 1 in the state where it is completely folded, and FIG. 2(d) is a rear view of the paper 1 in the state where it is completely folded. FIG. 3 is a perspective view showing a schematic configuration of the paper 1 of the paper product 100 according to the present embodiment. FIG. 4 is a front view showing a schematic configuration of the cover 2 of the paper product 100 according to the present embodiment. FIG. 4(a) is a front view showing a state before the fold-in parts 25 and 26 are formed, and FIG. 4(b) is a front view showing a state after the fold-in parts 25 and 26 are formed. FIG. 5 is a front view showing a state of the paper product 100 according to the present embodiment in use. FIG. 5(a) is a front view showing the first page 12 and the second page from the first to the last page of paper 1 when opened, FIG. 5(b) is a front view showing the middle page of paper 1 when opened, and FIG. 5(c) is a front view showing the last page 13 and the penultimate page of paper 1 when opened. 2 to 5, the paper product 100 according to this embodiment includes a sheet 1 and a cover sheet 2. Both the sheet 1 and the cover sheet 2 are made of paper such as Japanese paper.

[0014] As shown in Fig. 3 etc., the paper 1 is a folded book type paper that is folded accordion-like into multiple sheets along creases 11. Note that, although illustrations of characters and figures written on the paper 1 are omitted in Figs. 2, 3 and 5, when the paper craft product 100 is a sutra book, the characters of the sutra are written in advance on the paper 1. Also, when the paper craft product 100 is a writing book or a red seal book, ruled lines etc. may be written in advance. The thickness of the paper 1 (before folding) is, for example, 0.05 mm or more and 0.2 mm or less.

[0015] The cover 2 is used to sandwich and bind the paper 1. The cover 2 may be plain, or may have an appropriate pattern to enhance its decorativeness. As shown in Fig. 4(a), cover sheet 2 is formed from a single sheet. Cover sheet 2 has creases 21, 22, 23, and 24. Both ends of cover sheet 2 are folded inward along creases 21 and 24, respectively (by folding edges 2a and 2b of cover sheet 2 so that they are positioned more inward than in the state shown in Fig. 4(a)), forming fold-in portions 25 and 26 (overlapping portions of cover sheet 2) as shown in Fig. 4(b). The thickness of the cover 2 (the thickness of one sheet) is preferably equal to or greater than the thickness of the paper 1 (the thickness before folding), and is, for example, 0.1 mm to 0.4 mm.

[0016] As can be seen from Figures 2(a), 2(b) and 5, the height of cover 2 (dimension H2 shown in Figure 4(a)) is the same as the height of paper 1 (dimension H1 shown in Figure 3). Also, the distance W2 between crease 21 and crease 22 (and the same for the distance between crease 23 and crease 24) on cover 2 shown in Figure 4(a) is the same as the width W1 of each page of paper 1 shown in Figure 3. Furthermore, the distance T2 between crease 22 and crease 23 on cover 2 shown in Figure 4(a) is the same as the thickness T1 of paper 1 in a completely folded state shown in Figure 2(b). Then, as shown in Figures 2(a) and 5, the first side 12 of sheet 1 is inserted into one fold-in portion 25 of cover 2 (inserted between the overlapping covers 2 at fold-in portion 25 so that edge 1a of the first side 12 of sheet 1 approaches fold line 21 of cover 2), and the last side 13 of sheet 1 is inserted into the other fold-in portion 26 of cover 2 (inserted between the overlapping covers 2 at fold-in portion 26 so that edge 1b of the last side 13 of sheet 1 approaches fold line 24 of cover 2), so that sheet 1 is sandwiched between covers 2 and bound. Although the cover 2 in this embodiment has creases 22 and 23, if the sheet forming the cover 2 is thin and easy to bend, it is not necessary to provide these creases 22 and 23. If the distance between crease 21 and crease 24 on the cover 2 (=2×W2+T2) is equivalent to the dimension calculated by adding the width W1×2 of each page of paper 1 and the thickness T1 of paper 1, the paper 1 can be sandwiched between the cover 2 and bound.

[0017] As described above, the paper craft 100 according to this embodiment is not configured such that the paper 1 is attached to the cover 2, but rather the first page 12 and the last page 13 of the paper 1 are inserted into the fold-in portions 25 and 26 of the cover 2, respectively, so that the paper 1 can be replaced. That is, for example, if the paper craft 100 is a stamp book, after a stamp has been written on all the pages of the paper 1, a new paper 1 on which no stamp has yet been written can be sandwiched and bound in the same cover 2. Furthermore, the paper product 100 of this embodiment does not have a separate cover 2 but is formed from a single sheet, which makes it easy to handle and prevents the paper 1 from opening on its own or inadvertently.

[0018] Fig. 6 is a front view showing a schematic configuration of a modified cover included in the paper product 100 according to the present embodiment. Fig. 6(a) is a front view showing the modified cover 2A before the fold-in portions 25, 26 are formed, and Fig. 6(b) is a front view showing the modified cover 2A after the fold-in portions 25, 26 have been formed. As shown in Fig. 6, cover sheet 2A according to the modified example differs from cover sheet 2 shown in Fig. 4 described above in that cover sheet 2A has resin layer 27 applied near folds 21, 24 of cover sheet 2A, the resin having a higher coefficient of friction with paper 1 than cover sheet 2A, but the rest of the cover sheet has the same configuration as cover sheet 2 described above. Here, "near folds 21, 24 of cover sheet 2A" refers to the area where edge 1a (see Fig. 5) of first page 12 of paper 1 to be inserted into fold-in portions 25, 26 and edge 1b (see Fig. 5) of last page 13 of paper 1 may be located. An example of the resin that forms resin layer 27 is a silicone resin.

[0019] According to the cover 2A of the modified example, the cover 2A has a resin layer 27 applied near the folds 21, 24, which has a resin with a higher coefficient of friction with respect to the paper 1 than the cover 2A. As a result, the friction force generated between the first surface 12 and the last surface 13 of the paper 1 inserted into the fold-in portions 25, 26 and the resin layer 27 is greater, making it more difficult for the first surface 12 and the last surface 13 of the paper 1, and ultimately the entire paper 1, to slip relative to the cover 2A. Therefore, with the cover 2A of the modified example, while retaining the advantage of being able to replace the paper 1, the paper 1 is less likely to slip relative to the cover 2A, making it even easier to handle than when the cover 2 described above is used.

[0020] In the example shown in FIG. 6, the resin layer 27 is provided along the entire length of the folds 21, 24, but this is not limited to this, and it is also possible to adopt a configuration in which the resin layer 27 is provided along a portion of the longitudinal direction of the folds 21, 24. Also, in addition to or instead of the vicinity of the folds 21 and 24, it is possible to adopt a configuration in which the resin layer 27 is provided in a portion other than the vicinity of the folds 21 and 24 (for example, the vicinity of the folds 22 and 23, etc.).
