Description

  The present invention relates to a notebook used in daily use, business use, or specialized fields such as academic, fine art, music, and art, and particularly relates to a notebook having a seamless spread page.

  Conventionally, as a bookbinding method, a booklet binding method in which a stack of sheets (a signature that has been collated) is sewn with a thread using a sewing machine, and the back side is bound with an adhesive. Stapling, double rings, bookbinding with a spiral wire, and the like are known. Among these, the perfect binding is widely used because it can be bound at a relatively low cost and has an advantage that it can easily deal with a booklet having a large number of pages. On the other hand, since perfect binding cannot open the root of the throat (center) of the booklet, it cannot handle the description of the expression across the spread pages, and the rise of the throat impairs the feeling of use when writing notes. When copying the entire surface, there is a problem that it is not easy to copy the throat.

  Patent Literature 1 and Patent Literature 2 have been proposed as a method for binding a notebook or the like having good spreadability in perfect binding. In Patent Document 1, the back glue is adhered after coating by allowing a release agent to be present between the back glue coated on the back of the text, which is a signature that has been collated, and the inner surface of the cover. Even if the cover is put on the main body and bonded with throat glue while maintaining the properties, the back of the main text and the inner surface of the cover are separated without being bonded. It is said that sex can be secured.

  Further, in Patent Document 2, the back portion of the text is hardened with a first adhesive having a predetermined viscosity relatively lower than that of the second adhesive, and after the surface of the adhesive layer is solidified, the first adhesive is used. However, by applying a second adhesive with a relatively high viscosity and fixing it to the inner surface of the back portion of the cover material, the flexibility of the adhesive layer is improved and good spreadability can be secured. It is said.

  In addition, although it is not a notebook, in Patent Document 3, as an interleaf binding machine that binds albums, map books, picture books, etc., it is glued to one of the outer sides of the printing paper folded so that the printing surfaces face each other, There has been proposed one in which these are sequentially overlapped and joined.

JP 2004-188863 A Japanese Patent No. 5743362 Japanese Patent No. 4135923

  However, in the embodiment in which the back of the laminated body in which the sheets are overlapped in the notebook is fixed, there is a seam in at least one spread page, and it is not possible to have a structure in which all the spread pages are seamless. For this reason, it is not possible to sufficiently cope with an application (for example, a musical score or the like) that requires a description that extends over a spread page. Further, as long as the back surface of the text is fixed with an adhesive, it is not easy to make the spread pages completely flat (flat) depending on the number of pages of the text or the type of adhesive. Note that, even in the case of notebooks that are not saddle-stitched binding, for example, saddle-stitched binding, it is not possible to have a seamless configuration on all spread pages.

  On the other hand, in the slip-sheet binding machine as in Patent Document 3, it is possible to perform seamless binding on a spread page. However, albums, map books, picture books, and the like that are bound by such a slip-sheet binding machine use relatively thick printing paper, and printing paper having a thickness used as a normal notebook is not used. Further, if it is technically possible in the slip-sheet binding machine, there is no problem even if a map book or a picture book is bound using thin printing paper (for example, 0.12 mm or less). However, the notebook is written by a person on the page, and depending on the application state of glue (adhesive) between the combined papers, there are cushions and unevenness due to the glue. It is not easy to ensure practicality at the time of writing, such as difficulty in writing.

  In addition, with the recent trend toward paperless digitalization, the demand for handwritten paper notes is decreasing. However, a paper notebook has many advantages such that it is difficult to obtain with a digital device, is low in cost, excellent in handleability, and hard to lose a record. While taking advantage of such advantages, it is considered that demand can be improved by providing unprecedented added values such as the above-described flattening, prevention of ink set-off, and response to enlargement.

  The present invention has been made in view of such a background, and an object of the present invention is to provide a notebook in which a spread page is seamless, the spread page can be made completely flat, and practicability at the time of writing is ensured. . It is another object of the present invention to provide a notebook that can prevent the ink from being set off in addition to the above characteristics and can be opposed to an increase in size.

  A first notebook of the present invention is a notebook having a seamless spread page, and the notebook is composed of a plurality of paper units, and each paper unit is composed of a single sheet folded in two. The plurality of paper units are aligned and overlapped so that the folds of the respective paper units are located on the same side, and the overlapping surfaces of adjacent paper units are directly or separately stacked. Bonding is performed with a sheet interposed, and the bonding is made by glue applied to substantially the entire surface except for the application part other than the outer edge part on the bonding surface, and the spread page is one of the sheet units. It is characterized by comprising a single sheet of paper.

  The second notebook of the present invention is a notebook having a seamless spread page, and the notebook is composed of a plurality of paper units, and each paper unit is a sheet of paper folded in three or four. The plurality of paper units are aligned and overlapped so that the folds of the respective paper units are in the same positional relationship, and overlapping of adjacent paper units. The mating surfaces are joined directly or with another sheet interposed, and the joining is made by glue applied to substantially the entire surface except for the non-applied portion other than the outer edge portion on the joining surface. The sheet unit is composed of one sheet constituting one of the sheet units, and has a shape obtained by developing a three-fold or four-fold.

  The third notebook of the present invention is a notebook having a seamless spread page, and the notebook is composed of a plurality of paper units, and each paper unit is composed of a single cross-folded sheet, The plurality of paper units are aligned and overlapped so that the crease part of the second fold of each paper unit is positioned on the same side, and the plurality of paper units are overlapped with each other. The overlapping surface is joined directly or with another sheet interposed, and the joining is made by glue applied to substantially the entire surface except for the non-coated portion other than the outer edge portion on the joining surface, and the spread page is The sheet unit is composed of one sheet constituting one of the sheet units, and has a shape in which a cross fold is developed.

  In the first to third notebooks of the present invention, the non-application part is arranged in a lattice pattern on the joint surface. As another form, the paste is applied in a lattice shape on the joint surface, and the space between the lattices is the non-application portion.

  In the first to third notebooks of the present invention, when the overlapping surfaces of the adjacent paper units are directly joined, the overlapping surface of the adjacent paper units is different from the at least one adjacent overlapping surface. When the sheet is joined with a predetermined pattern printed on the surface of the other sheet, the pattern is transmitted and visible on the sheet surface on the writing side. Features.

  The first notebook of the present invention comprises a plurality of paper units, each paper unit comprising one folded sheet (thickness of 0.12 mm or less), and the plurality of paper units are each paper unit. The folds are aligned and overlapped so that they are located on the same side, and the overlapping surfaces of adjacent paper units are joined, and this joining is performed except for the non-application part other than the outer edge part on the joining surface. Since the spread page is made of a sheet of paper that forms one of the paper units, the spread page is seamless, and the spread page is completely flat while the spread page is usually flat. It is easy to write as in the case of one sheet of paper, and practicability at the time of writing is ensured. For this reason, it can utilize suitably for preparation of drawing, a table | surface, a score, a ruler display etc. which require the description which spreads over a facing page. Further, since there is no seam or unevenness in the center of the spread page, the usability at the time of writing is excellent, and copying of the entire spread page is easy. In addition, since the writing pages are joined by overlapping two sheets of paper, the ink can be transferred to the back page when writing using a pen with a penetrating ink as well as a normal pencil or fluorescent pen. Can be suppressed.

  In the second notebook of the present invention, the paper unit is changed from the first notebook configuration to a single sheet of paper folded in three or four, and the spread page constitutes one of the paper units. Since it consists of one sheet of paper and has a shape in which the three-fold or four-fold winding is developed, in addition to the effect of the first note, the spread page has an area 1.5 to 2 times the normal spread page. It can be secured. For this reason, it can utilize suitably also for the use for which a longer expression is required.

  The third notebook of the present invention is obtained by changing the paper unit from the first notebook configuration to a single cross-folded paper, and a spread page is formed from one paper constituting one of the paper units. Thus, since the cross-folded shape is developed, in addition to the effect of the first notebook, it is possible to secure an area twice as large as a normal spread page in the spread page. For this reason, a large writing area can be secured even with a small notebook size.

  In addition, since the non-applied portions are arranged in a grid pattern on the joint surface, the paste is also applied in a regular pattern, the unevenness of the paste layer is reduced, the variation in thickness can be reduced, and writing is easier. It becomes a note. In such a form, the same effect can be obtained when the configurations of the glue and the non-applied portion are reversed and the glue side is in a lattice shape.

  Also, when the overlapping surfaces of adjacent paper units are directly bonded, the overlapping surface of adjacent paper units is bonded to at least one adjacent overlapping surface with another sheet interposed A pattern such as a ruled line or a pattern is printed on the surface of the other paper, and the pattern is transparent and visible on the paper surface on the writing side. The paper surface itself on the writing side is blank and easy to write. Further, there is a sense of quality compared to the case where these patterns are printed directly on the paper surface on the writing side.

It is the perspective view etc. which show an example of the notebook of this invention. 2 is a side view of the notebook of FIG. It is a figure which shows the bookbinding process of the notebook of FIG. It is a figure which shows the other example of the notebook of this invention. It is a figure which shows the other example of the notebook of this invention. It is a figure which shows the form which permeate | transmits a pattern etc.

An embodiment (first note) of the notebook of the present invention will be described with reference to FIGS. FIG. 1A is a perspective view showing the notebook, and FIG. 1B is an enlarged view of the vicinity of the binding portion. 2A is a perspective view of the notebook, FIG. 2B is a side view of an arbitrary page (3 patterns), and FIG. 2C constitutes one page. It is an enlarged side view of a sheet.
As shown in FIG. 1A, the note 1 is a note having a spread page 3 with no joint. As shown in FIG. 1B, the notebook 1 is formed by stacking a plurality of paper units 2 made of a single folded sheet. Each paper unit 2 is overlapped with its orientation aligned so that the crease 2a is located on the same side. Here, the overlapping surfaces of the adjacent paper units 2 are directly joined by the glue 6. The notebook 1 is rolled so as to widen the fold part 2 a of the paper unit 2. For this reason, the spread page 3 is composed of one sheet constituting one of the sheet units 2. Further, the bookbinding tape 5 is attached to the back portion (binding portion) of the notebook 1. This bookbinding tape 5 is for reinforcing the connection between the paper units and improving the appearance. Since the units of the present invention are firmly joined on the overlapping surface, the notebook of the present invention is established as a notebook even when there is no bookbinding tape.

  As shown in FIG. 2A and FIG. 2B, the notebook 1 can make the spread page 3 completely flat regardless of which page is turned. Since there is no seam or unevenness in the center of the spread page, there is no catch when writing, and there is no problem that the throat portion is not reflected even when copying the entire spread page. Further, as shown in FIG. 2C, each page 4 serving as a writing page is joined by overlapping two sheets 2 ′ of adjacent sheet units with glue 6. It is not simply a stack of two sheets of paper, but the entire surface is joined with glue, so there is also an adhesive layer between the back and back surfaces, so even if you use an oil-based or water-based pen, etc. It is possible to prevent bleeding to the back page.

Here, the type of the paper 2 ′ used in the paper unit is not particularly limited as long as the thickness of the paper is 0.12 mm or less. Copy paper, copy paper, art paper, coated paper, matte paper, high-quality paper Any paper such as can be used. These papers may be used alone or in combination. The sheet thickness t ₀ is preferably 0.06 mm to 0.12 mm, more preferably 0.08 mm to 0.12 mm, and even more preferably 0.08 mm to 0.10 mm. The thickness t ₁ of the paper constituting each page 4 is 2t ₀ . By using thin paper, it is possible to obtain a feeling of use equivalent to that of a normal notebook while overlapping two pages. In addition, the number of stacked sheet units is not particularly limited, and can be, for example, about 10 to 300 sheets.

  The manufacturing process of this notebook will be described with reference to FIG. FIG. 3 is a view showing a bookbinding process of the notebook of FIG. First, the sheet 2 ′ is bent (folded in half) at the substantially central crease 2 a to form the sheet unit 2. The paper units 2 are aligned and pressed in order so that the crease portions 2a are positioned on the same side, and are joined by pressing. Here, before superimposing, the paste 6 is applied to the overlapping surface 2b of the paper unit 2 to be the bonding surface. By solidifying the glue, the paper unit is integrated and a notebook 1 '(without bookbinding tape) is obtained. This series of manufacturing steps can be carried out using a known slip-sheet binding machine except for the paste application portion as described below.

  In the example shown in FIGS. 1 to 3, the overlapping surfaces of the adjacent paper units 2 are directly joined, but the present invention is not limited to this, and another paper may be interposed. Here, the “joining surface” that is glued between the paper units in the present invention is the overlapping surface of each paper unit when the overlapping surfaces of adjacent paper units are directly joined. In the case where another sheet is interposed, these are the overlapping surface of each sheet unit and both surfaces of another sheet. It should be noted that at the time of bonding, it is sufficient that glue is applied to at least one of the bonded surfaces to be bonded.

  The present invention is characterized in that the glue used for joining is applied to substantially the entire surface of the joining surface except for the non-application part other than the outer edge part. That is, a portion (non-application portion) that is applied to substantially the entire surface but is not applied to a part is provided. Even in the case of normal entire surface application, there is a case where no gluing is applied to a small range of the outer edge portion, but in the present invention, not such an outer edge portion but a non-application portion is also provided at the center of the joint portion. Yes. By providing such a non-applied part, when pressing and joining, a part of the glue escapes to the non-applied part, and the unevenness of the glue layer between sheets can be reduced. . In particular, the present invention is intended for notebooks that are premised on writing, and because thin paper is laminated, the structure of the glue layer is important in order not to impair the feeling of use during writing. .

  In the example shown in FIG. 3, the non-application part 6a of the glue 6 is formed as a mesh-like part arranged in a lattice pattern on substantially the entire joining surface. That is, on one side of the paper unit 2 that is the bonding surface, the paste 6 is not applied to the lattice portions, and the paste 6 is applied to the interstices (mesh). By making the non-applied portion into such a regular pattern, the unevenness of the glue layer can be reduced and the variation in thickness can be reduced. Further, compared to the case where there is no grid-like non-applied portion, the drying speed of the glue is increased, and the warped paper with time can be prevented.

  The size of the lattice is not particularly limited as long as it maintains a sufficient strength at the joint surface and does not impair the usability. For example, it is preferable that the length of the rhombus diagonal line is about 0.8 mm to 1.2 mm, and the line width of the lattice itself is about 0.08 mm to 0.12 mm as the interstices (mesh) of the rhombus. As another form, the paste may be applied in a lattice shape so that the space between the lattices becomes a non-application portion. In this case, it is preferable to make the line width of the lattice itself larger than that in the case of FIG. 3 and to ensure a sufficient amount of glue on the joint surface.

  Such a grid-like non-coating portion 6 is, for example, a known slip-sheet binding machine in which a grid-like groove is formed on the surface of a gluing roller, a mesh-like gluing roller, or the above gluing This can be done by preparing a glue plate or the like that can transfer the shape. As the glue, starch-based glues, acetic acid-based emulsion-type glues, and the like, known glues can be appropriately used. Moreover, the density | concentration of the paste to apply | coat can also be adjusted by thinning suitably. Among these, it is preferable to use starch paste. For example, in the form in which the grid-like non-coating portion is provided, by using starch-based glue, moisture in the glue immediately after the sheets are bonded can be quickly dried, and the paper can be prevented from warping with time.

  In the non-applied part of the glue, a part of the glue escapes to the non-applied part when pressed, and therefore, in the notebook which is the final product, the glue also enters and solidifies in a part of the notebook. However, a part of the non-applied portion remains without any paste, and it can be confirmed that the non-applied portion was present at the time of manufacture in the product. The above-mentioned lattice-shaped non-application part can also grasp | ascertain the state which the lattice shape remained substantially by cutting the page of a product note or peeling a junction part.

  Another embodiment of the notebook of the present invention (second notebook) will be described with reference to FIG. FIG. 4A is a perspective view showing the notebook, and FIG. 4B is an enlarged view of the vicinity of the opening side. As shown in FIG. 4A, the notebook 11 is obtained by changing the first notebook configuration shown in FIG. 3 to a sheet 12 'that is wound in three and folded in three. The paper 12 'is first folded at the crease portion 12b, and then folded at the crease portion 12a so as to be wound (trifold winding). The sheet unit 12 is aligned and overlapped so that the two fold portions 12a and 12b have the same positional relationship. As shown in FIGS. 4A and 4B, the overlapping surface 12 c of the adjacent paper units 12 is directly joined by glue 16. Further, a bookbinding tape 15 is attached to the back portion (binding portion) of the notebook 11. The notebook 11 is rolled so as to widen the crease portion 12a of the paper unit 12, and then is rolled up so as to further widen the fold portion 12b. For this reason, the spread page 13 is composed of a single sheet 12 'constituting one of the sheet units 12, and has a shape obtained by unfolding the winding trifold. Note that only the extended page 14 'is a page for one sheet.

  The configuration of the non-application portion 16a of the glue 16 on the joint surface is the same as the configuration of the first notebook, and the bookbinding process after preparing the paper unit is the same. Further, as a modification of FIG. 4, the paper unit 12 may be changed to a paper that is wound into four. The four-fold winding may be a four-fold winding.

  In addition to the effect of the first note, the second notebook 11 can secure an area of 1.5 times (three folds) to two times (four folds) of a normal spread page in the spread pages. For this reason, it can be used for applications that require longer expressions such as drawings, tables, musical scores, and chronologies. In addition, when using a notebook as a schedule book, one spread page is used every month, and a calendar and schedules using a large area can be collectively written. Furthermore, since a long and flat page can be formed, simple measurement can be performed by printing a ruler or a dimension line.

  Another embodiment (third note) of the notebook of the present invention will be described with reference to FIG. FIG. 5 is a perspective view showing the notebook. As shown in FIG. 5, the notebook 21 is obtained by changing the sheet unit 22 from the first notebook configuration of FIG. 3 to one sheet 22 ′ that is cross-folded. The sheet 22 ′ is first bent at the fold portion 22 b and further bent at the fold portion 22 a (cross fold (field shape fold)). The paper units 22 are aligned and overlapped so that the second fold portion 22a of the cross fold is positioned on the same side. Further, the overlapping surfaces 22 c of the adjacent paper units 22 are directly joined by the glue 26. Further, a bookbinding tape 25 is attached to the back portion (binding portion) of the notebook 21. The notebook 21 is rolled so as to widen the fold portion 22 b of the paper unit 22 and then rolled so as to further widen the fold portion 22 b. For this reason, the spread page 23 is formed of a single sheet 22 ′ constituting one of the sheet units 22, and has a shape in which the cross-fold is developed. The extended page 24 'is a page for one sheet.

  The configuration of the non-coating portion 26a of the glue 26 on the joint surface is the same as that of the first notebook, and the bookbinding process after the paper unit is prepared is the same. In addition to the effect of the first note, the third note 21 can secure an area twice as large as a normal spread page in the spread page. For this reason, the writing area becomes four times the area of the closed state of the notebook, and a large writing area can be secured while improving the portability by reducing the size of the notebook. In addition, by using a general A4 size notebook, it is possible to prepare a spread page of A2 size (4 times A4).

  Based on FIG. 6, the form which permeate | transmits a pattern etc. is demonstrated. As shown in FIG. 6, another sheet 7 is sandwiched between the sheet units 2. Here, a pattern 8 is printed on the separate sheet 7. For this reason, when the paper units 2 are joined to each other with the other paper 7 interposed, the pattern 8 can be permeated and visually recognized on the paper surface on the writing side. As the pattern 8, in addition to various patterns and patterns as a background, a practical pattern such as a ruled line can be described. Since the paper surface itself on the writing side is a white paper, it is sufficiently easy to write even if the pattern is transmitted. Further, as another form, a similar pattern or the like may be described on the outer surface (overlapping surface) of the paper unit, and another paper may not be interposed. In this case, the same visual effect can be obtained.

  As mentioned above, although the form of the notebook was demonstrated based on each figure, the whole structure of the notebook of this invention is not limited to this.

  The notebook of the present invention has no joints in the spread pages, and the spread pages are completely flat, and the spread pages are easy to write on the spread page surface as in the case of a normal sheet of paper, and can be prevented from being set off. It can be widely used as notebooks used in business applications or specialized fields such as academic, art, music, and art. For example, it can be used as a normal study notebook for study and recording, a notebook for design drawings, a sketch book, a score book, a memo pad, a schedule book, and the like. In particular, the present invention can be suitably used for applications that require written description over spread pages (for describing design drawings, musical scores, and schedules).
