Description

Pamphlet

[0001] The present invention relates to a pamphlet represented by notebooks, books, catalogs, pamphlets, etc.

[0002] Conventionally, various pamphlets such as notebooks and books have been provided. Such pamphlets are provided in various types according to their uses and purposes. In such notebooks and books, the ability to be opened out flat is often emphasized.

[0003] On the other hand, regarding the binding method, there are methods such as thread binding, case binding, and perfect binding. From the perspective of productivity, perfect binding is often used. In particular, as a type of perfect binding with improved ability to be opened out flat, the type disclosed in Patent Document 1 of the following prior art documents has been implemented.

[0004] Patent Document 1 uses two predetermined types of adhesives, but is not limited to such adhesives, and there is room to consider other simpler methods. Also, in this case, it is preferably excellent in binding strength. Note that Patent Documents 2 and 3 relate to other binding apparatuses.

[0005] Patent No. 5743362 JP-A-2009-202477 JP-A-2003-260886[[ID=十六]] [[ID=十七]]

[0006] Therefore, the inventor made it an issue to achieve both better productivity and the ability to be opened out flat like a single sheet of paper while maintaining binding strength. [[ID=二十]]

[0007] As a result of the inventor's intensive research, by laminating a single double-folded sheet of paper so that the folding directions thereof coincide, and making a pamphlet with a relatively simple structure in which regions at a predetermined interval from the fold are continuously adhered, it has been found that it is possible to achieve both the ability to be opened out flat and binding strength, and the invention has been completed. That is, the first invention is "a pamphlet in which a plurality of single double-folded sheets of paper are laminated so that the folding directions thereof coincide, and regions at a predetermined interval from the fold are connected".

[0008] Furthermore, in the first invention, it is preferable to provide a fold line on one side of the folded paper at a predetermined distance from the fold. That is, the second invention is "the booklet according to claim 1, wherein a fold line is provided on one side of the folded paper at a predetermined distance from the fold."

[0009] Next, in the first or second invention, the booklet can be used as a notebook, book, catalog, or pamphlet. That is, the third invention is "the booklet according to claim 1 or 2, wherein the booklet is a notebook, book, catalog, or pamphlet."

[0010] Next, in the first or second invention, it is preferable to further attach and add a spine adhesive to the folded side of the booklet. That is, the fourth invention is "the booklet according to claim 1 or 2, wherein a spine adhesive is added to the folded side of the booklet."

[0011] By utilizing the present invention, it is possible to create a booklet that achieves excellent open-page flexibility and binding strength. Furthermore, this booklet can be suitably used for notebooks, books, catalogs, or brochures.

[0013] The present invention will be described below with reference to embodiments. However, the present invention is not limited to these embodiments. The present invention relates to a "booklet formed by stacking multiple sheets of paper folded in half and connecting areas at predetermined intervals from the folds."

[0014] (Booklets and Paper Materials) In this invention, a booklet refers to a laminate made of stacked paper materials (laminated paper materials) in which each page can be opened. Furthermore, the paper materials may be not only paper, but also laminated with other materials such as plastic (plastic sheets, etc.). In the case of paper, the color (e.g., white or gray) and type are not particularly limited, however, paper with high flexibility is preferred because, for example, the softness of the paper affects the binding properties of the booklet described later in this invention. Flexibility varies depending on the paper material and additives used to impart color, but is generally determined by the basis weight. In this case, the basis weight is generally 70 to 100 g / m². ２ It is preferable that this is the case, and within this range, a higher degree of flexibility is preferable.

[0015] Furthermore, the booklet can be suitably used for notebooks, books, catalogs, or brochures, etc. However, it is not limited to these, and includes all types of booklet forms. The booklet can be made in various sizes such as A4 (297 x 210 mm), B5 (257 x 182 mm), A5 (210 x 148 mm), and B6 (182 x 128 mm). However, the booklet of the present invention can of course be made in sizes other than those listed above.

[0016] Generally speaking, for example, books typically come in A5 size (210 x 148 mm), Shiroku size (188 x 127 mm), and B6 size (128 x 182 x 128 mm). Magazines and textbooks come in A4 size (297 x 210 mm), AB size (257 x 210 mm), and B5 size (257 x 182 mm). Notebooks come in A4 size (297 x 210 mm), B5 size (257 x 182 mm), A5 size (210 x 148 mm), B6 ​​size (182 x 128 mm), and these are the most commonly used sizes.

[0017] In this invention, folded sheets of paper are stacked and used. That is, as shown in Figure 1, folded sheets of paper 1 are stacked so that the direction of the folds 3 is aligned. The number of sheets to be stacked depends on the thickness of the paper, but is generally around 2 to 200 folds (about 8 to 800 pages). Preferably, it is around 10 to 100 folds (about 40 to 400 pages). However, it is not limited to these.

[0018] Furthermore, when folding the paper in half, a known method of folding in half can be used for the fold line 3. However, in the case of paper, depending on the material of the paper, for example, if the paper is stiff, it may be difficult to fold in half. In such cases, a method can be used to make it easier to fold by pre-creasing the paper for folding in half. Alternatively, it is also possible to make it easier to fold by processing it with perforations or other methods. Furthermore, a method can be used to fix the fold by pressing the paper after it has been folded in half. These methods can improve the unfolding and other aspects of the finished booklet.

[0019] (Multiple Layers) In the present invention, as shown in Figure 1(1), multiple sheets of paper 1 that have been folded in half are layered so that the orientation of their folds 3 coincides. That is, the layers are stacked so that the sides of the folds 3 are aligned.

[0020] (Joining) In this invention, the folded sides of multiple stacked folded papers 1 are continuously joined (joined). For this purpose, as shown in Figure 1, adhesive areas for joining are provided at predetermined intervals from the side of the fold 3. Here, the predetermined interval is not particularly limited, but is generally about 2 to 10 mm from the fold 3. Preferably, it is about 3 to 8 mm. Most preferably, it is about 4 to 7 mm.

[0021] Furthermore, the adhesive area refers to the portion where the surfaces are bonded. Therefore, it is common practice to apply the adhesive 5 to one of the contacting surfaces and then bring the other surface into contact to bond them. For example, Figure 1(2) shows a configuration in which the adhesive 5 is applied only to the upper surface of the folded paper 1.

[0022] However, the invention is not limited to this, and of course, it is also possible to apply the adhesive 5 only to the bottom surface or to both surfaces. Figure 1(1) is a laminated image of the booklet of the present invention, and (2) is a cross-sectional view of (1) from A to A'.

[0023] The area to be bonded is usually the entire area at a predetermined interval from the fold 3, as shown in Figure 2(1), but it is not limited to this. For example, the bonded and non-bonded areas may be alternating, as shown in Figure 2(2), or the bonded areas may be limited to the vicinity of the fold and the edges of the bonded area, as shown in Figure 2(3). Furthermore, various types of adhesive 5 can be used, such as starch-based adhesives and synthetic resin-based adhesives. Various types, such as liquid and particulate, can also be used. As mentioned above, the type of adhesive 5 is not limited, but from an environmental standpoint, a water-based adhesive (e.g., aqueous emulsion) is preferred. By using a water-based adhesive, when the booklet 9 of this invention is suspended in water for recycling, the adhesive can be easily separated from the paper, making it easier to reuse the booklet of this invention through recycling.

[0024] (Fold line) Next, in the present invention, as shown in Figure 3, it is also preferable to provide a fold line 7 on one side of the folded paper at a predetermined distance from the fold line 3. By providing a fold line, the effect of opening the booklet 9 can be improved.

[0025] In Figure 3, (1) is a laminated image of the booklet 9 when the fold line 7 of the present invention is added, and (2) is a cross-sectional view of (1) A-A'. Here, the fold line 7 refers to a line (line) that makes the paper easier to fold when the page is opened, such as a perforation. For example, various methods can be used, such as perforations made at regular intervals or methods that pre-form a crease. These methods can be selected as appropriate.

[0026] Furthermore, when using perforations as the fold line 7, it is preferable that the ratio of perforated to unperforated lengths is in the range of 1:1 to 5:1. More preferably, it is preferable that the ratio of perforated to unperforated lengths is in the range of 2:1 to 4:1. Most preferably, it is in the range of perforated to unperforated lengths of approximately 3:1. The size of the perforations is not particularly limited. However, generally, it is in the range of approximately 0.5 mm to 30 mm. More preferably, it is in the range of approximately 1 mm to 10 mm.

[0027] Furthermore, if the intention is to make the fold line less noticeable, using graph paper is also an effective method. By aligning the lines of the graph paper with the lines of the fold line 7, the fold line 7 can be made less noticeable. Conversely, if it is necessary to make the fold line 7 more noticeable, it is possible to avoid aligning the lines of the graph paper with the lines of the fold line 7. Additionally, it is possible to make the lines of the fold line 7 darker to make them more prominent.

[0028] Furthermore, when a fold line 7 is added, the adhesive area must be located on the side of the fold 3 beyond the fold line 7. In this case, when a fold line 7 is added, it is possible as long as the adhesive area is located on the side of the fold beyond the fold line 7, but as shown in Figure 4, the boundary of the adhesive area does not necessarily have to coincide with the fold line.

[0029] Alternatively, the fold line 7 can be made to roughly coincide with the boundary of the adhesive area. That is, as shown in Figure 5, by making the fold line 7 the boundary of the adhesive area, the effect of opening the booklet 9 more quickly can be achieved. However, when considering actual manufacturing, it is preferable to apply the adhesive area in a strip-like manner to the center of the width from the fold line 3 to the fold line 7 when the paper is folded in half, as shown in Figure 4. For example, in the embodiment of Figure 4, it is preferable to set the width from the fold line 3 to the fold line 7 to 5 mm, and to create an adhesive area with a width of about 2 mm in the center and apply glue or the like.

[0030] By doing this, as will be described later, when gluing and stacking folded paper, any irregular misalignment of the glue can be kept within a 5 mm range, preventing the glue from reaching the area of ​​the fold line 7. Furthermore, as shown in Figures 1 and 3, the folded paper at the top or bottom of the paper stack may, if necessary, be left without the fold line 7.

[0031] Furthermore, as shown in Figure 3, it is preferable to apply the fold line 7 to only one side of the folded paper 1. In addition, when stacking, it is preferable that the sides on which the fold line 3 is applied are in the same orientation. For example, in Figure 3, the side with the fold line 3 is positioned on the bottom side of the booklet (laminated paper) 9, but it may also be positioned on the top side. Also, the completed booklet 9 may open from the right or from the left, and of course, the side with the fold line may appear on either the left or right side of the paper. This point will be described in more detail later.

[0032] (Spine Gluing, etc.) Next, as shown in Figure 6, it is preferable to add spine glue 11 to the folded side of the laminated and connected booklet (laminated paper body) 9. Adding spine glue 11 makes it possible to further ensure the integrity of each page of the booklet. It is preferable to use a thin material that is resistant to tearing as the material for spine glue 11. More specifically, for example, cheesecloth (a cloth-like material woven in plain weave with threads such as hemp or cotton) may be used, or other materials may be used. This makes it possible to bond the entire area of ​​the folded edge, which may reduce the misalignment of the paper in the laminate. It may also make it possible to reduce tearing of the folded paper on the front and back sides.

[0033] Furthermore, for the booklet 9, the folded paper at the top or bottom edge may serve as the front or back cover, but if necessary, a separate cardboard front or back cover may be added, and of course, these pages do not need to be folded in half. Moreover, if necessary, some pages may be added that are not folded in half. When adding a front or back cover, various methods can be used, but for example, as shown in Figure 7, the front cover 13 and back cover 15 may be attached to a surface cover 17 such as a cloth material, leaving an area in the spine of the booklet (laminated paper) 9 open, and the front and back surfaces of the booklet (laminated paper) 9 may be attached to the front cover 13 and back cover 15.

[0034] Furthermore, in this case, any of the following forms are possible: a type in which the spine of the laminate is not in close contact with the surface cover 17 of the booklet 9 (hollow back), a type in which the spine of the laminate is in close contact with the surface cover 17 of the booklet 9 (tight back), or a tight back in which the spine of the material of the surface cover 17 is particularly flexible, and the part in close contact between the surface material and the spine of the laminate bends inward together with the surface spine (flexible back). Moreover, it goes without saying that a hard cover, a cover, or an elastic band may be added to the booklet 9 or a booklet 9 with a cover or the like added thereto.

[0035] (Function, binding strength, and effect of the booklet) In booklet 9, when the pages are turned in order, the state in which the fold line 3 is not visible (the state in which the fold line 7 is visible) and the state in which the fold line 3 is visible alternate when the pages are turned in order. For example, Figure 8 shows the relationship between the fold line 3 and the fold line 7 when a fold line 7 is added, especially in the case of left binding (left opening).

[0036] Here, we will describe a more specific form of the booklet of the present invention. Generally, booklets are bound on the left (opens on the left) or on the right (opens on the right), as shown in Figure 9. Typically, left-bound booklets are mostly horizontally written, while right-bound booklets are mostly vertically written. The booklet of the present invention can be bound on the left (opens on the left) or on the right (opens on the right).

[0037] Here, if we refer to the fold line 3 as the center axis and the fold line 7 as the off-center axis, then in both left-bound and right-bound cases, it is possible to choose between folding along the center axis as shown in Figure 10(1), folding along the off-center axis as shown in Figure 10(2) (where a step at the edge is visible on the left side when opened along the off-center axis), or folding along the off-center axis as shown in Figure 10(3) (where a step at the edge is visible on the right side when opened along the off-center axis). This can be selected depending on the position where the fold line 7 is applied (for example, in the configuration of Figure 3, whether the fold line 7 is applied to the top or bottom side).

[0038] Furthermore, it is possible to select either a mode in which the state of Figure 10(1) and the state of Figure 10(2) alternate each time the pages of the booklet are turned, or a mode in which the state of Figure 10(1) and the state of Figure 10(3) alternate each time. In other words, as the pages are turned sequentially, the fold line 3 of the upper part of Figure 10(1) is visible and the fold line 7 is not visible, and the fold line 3 of the upper part of Figure 10(2) or Figure 10(3) is not visible and the fold line 7 is visible, occurring alternately.

[0039] However, preferably, in the case of left-opening, it is preferable to select such that when the pages are turned sequentially, the state of Figure 10(1) and the state of Figure 10(2) alternate as a double-page spread. For example, when transitioning from the state of Figure 10(1) to the state of Figure 10(2), the new page can be opened simply by folding the paper along the off-center axis, and then when transitioning from the state of Figure 10(2) to the state of Figure 10(1), the new page is opened by lifting the off-center axis and folding the paper along the center axis, but because it has already been folded along the off-center axis, it tends to be relatively easy to open.

[0040] On the other hand, when transitioning from the state shown in Figure 10(1) to the state shown in Figure 10(3) in the case of left-opening, opening a new page requires lifting the off-center axis while folding the paper along the center axis. However, this may also require folding the paper along the off-center axis of the new page. In this respect, the transition is slightly more complicated for the user compared to the transition from the state shown in Figure 10(1) to the state shown in Figure 10(2).

[0041] Next, in the case of right-to-left opening, it is preferable to select a layout such that when the pages are turned sequentially, the two-page spread alternates between the state shown in Figure 10(1) and the state shown in Figure 10(3). The reason for this is the same as for left-to-right opening described above. When transitioning from the state shown in Figure 10(1) to the state shown in Figure 10(3) in right-to-right opening, the new page can be opened simply by folding the paper back along the off-center axis. Subsequently, when transitioning from the state shown in Figure 10(3) to the state shown in Figure 10(1), the new page is opened by lifting the off-center axis and folding the paper back along the center axis. However, because the paper has already been folded back along the off-center axis, it tends to be relatively easy to open.

[0042] On the other hand, when transitioning from the state shown in Figure 10(1) to the state shown in Figure 10(2) in the case of right-opening, when opening a new page, the off-center axis is lifted while the paper is folded back at the center axis to open the new page. However, this may also require folding the paper at the off-center axis of the new page. In this respect, compared to transitioning from the state shown in Figure 10(1) to the state shown in Figure 10(3), there is a tendency for the process to be slightly more complicated for the user.

[0043] Next, regarding the booklet of the present invention, good openability can be achieved because the paper can be completely folded in any of the states of FIGS. 10(1) and FIGS. 10(2) or 10(3). More specifically, as shown in FIG. 11, when folding back along the center axis 3 to turn the page, it can be completely folded back up to an angle of 180°. Also, when folding back along the offset axis 7, it can be completely folded back up to an angle of 180°.

[0044] Next, the booklet (paper laminate) 9 is also excellent in terms of binding strength. That is, in the case of ordinary perfect binding, the openability often decreases because the entire fixed area including the fold is treated with an adhesive, and if the treatment area with the adhesive is reduced to avoid this, the binding strength decreases and it becomes easy for pages to fall out.

[0045] On the other hand, as described above, since it is possible to surely bond each paper surface to each other through a plane, excellent binding strength can be achieved. That is, two sheets of folded paper can be continuously bonded and connected in a plane between the axes of the double-fold paper having the fold 3 (center axis) and the fold line 7 (offset axis). Thus, by adopting the configuration of the present invention, it is possible to realize good openability and excellent binding strength.

[0046] Next, as shown in FIG. 10, in the states of FIGS. 10(2) and 10(3), the paper surface becomes smaller by the width between the axes from the fold 3 to the fold line 7 for each page on the left and right, and in FIG. 10(2), at the left end of the left paper surface, a step twice the width between the axes occurs between the paper surface and the page below it. Similarly, in FIG. 10(3), a step occurs between the right end of the right paper surface and the page below it. Various methods can be used as camouflage for these steps. For example, by making the color of the paper a gray color where the step is not noticeable, it is possible to make this step less noticeable.

[0047] Furthermore, if a string or the like that is commonly indicated across a plurality of pages, such as a title, is arranged in the portion of the subsequent page that is visible at the step, then for this portion, since it is a portion that is commonly indicated on any page, it becomes possible to make the fact that it is a step less conspicuous. Also, as another method, it is also effective to show a specific pattern or the like as a portion that is commonly indicated on each page.

[0048] Specifically, in order to camouflage the presence of the step that occurs at the left end or the right end and make it less conspicuous, for example, as shown in FIG. 12, it is also preferable to add a mark 19 such as a certain pattern to the right end or the left end in the opened state of each page. Various figures, patterns, etc. of the mark 19 can be used as the mark. Although FIG. 12 shows a mode in which three dots are provided, various other patterns and the like can be used. By making the user visually recognize such a mark 19 of a pattern or the like when each page is opened, the user can have the presence of the step at the end camouflaged and make the step at the end less conspicuous. As a result, the user can use the booklet while particularly reducing the awareness of the step at the end.

[0049] (Method for manufacturing a booklet) Basically, a booklet (paper laminate) 9 can be manufactured by laminating and pressing those with an adhesive 5 added to a region at a predetermined interval from the fold 3 of the double-folded paper surface. Also, various methods can be used as a method for this. For example, FIG. 13 shows a mode in which a newly double-folded paper 1 is laminated from below on a booklet (paper laminate) 9 that has already been laminated and connected.

[0050] ]That is, it shows a type of increasing the number of laminated sheets by providing a booklet (paper laminate) 9 that has already been laminated and connected above the papers that are double-folded and have an adhesive 5 applied to the adhesive region, and pressing them. After setting the number of laminated sheets to a predetermined number by repeating this operation, it further shows a mode of completing the booklet 9 by adding a back sticker 11.

[0051] Furthermore, as an example of the configuration of a specific apparatus for this type of manufacturing method, the apparatus disclosed in Patent Document 2 can be cited as an example. Next, Figure 14 shows an embodiment in which a newly folded sheet of paper 1 is laminated from above onto a booklet (laminated sheet of paper) 9 that has already been laminated and connected.

[0052] In other words, this method involves folding paper sheets 1, which have adhesive 5 applied to the bottom, and supplying them from above onto an already formed booklet (laminated paper body) 9, and pressing them down to increase the number of layers. By repeating this operation, the booklet 9 can be made to a predetermined number of layers.

[0053] Next, Figure 15 shows a type in which adhesive 5 is applied to the adhesive area on the upper surface of an already formed booklet (laminated paper) 9, and new folded paper 1 is added from above and pressed to increase the number of laminated sheets in the booklet 9.

[0054] By repeating this operation, a predetermined number of layers can be achieved. As an example of the configuration of this type of apparatus, the apparatus disclosed in Patent Document 3 is cited. Next, Figure 16 shows a type in which, after folding multiple sheets of paper in half and applying adhesive, the folded paper sheets 1 are pressed together all at once to form a booklet (laminated paper body) 9. This operation allows for a predetermined number of laminated booklet 9 layers to be achieved. Note that the methods for forming the booklet (laminated paper body) 9 shown in Figures 13 to 16 are each examples, and other methods are, of course, also possible.

[0055] Next, the laminated booklet (paper laminate) 9 can be pressed to reduce its thickness as needed. In this case, when folding the paper in half as described earlier, it is preferable for the paper to be more flexible so that it is easier to make a fold, and the manufactured paper laminate is thinner, which reduces the displacement of the paper due to pressing. In practice, however, the folded paper is often glued together as described above to form a laminate, and the edges of the laminate are often finished by cutting the three sides other than the laminated surface of the fold 3, thus finishing the edges of the booklet 9.
