Description

The present invention relates to a paper file that can store documents and the like.

Conventionally, this type of paper file has generally been a sheet of paper folded in half and bound on one side, but since it is made of paper, most of the files cannot be seen inside. Therefore, there is also a paper file made by layering paper that is transparent and paper that is not transparent (see Patent Document 1). When manufacturing a paper file by stacking papers in this way, it is common to adhere them with glue.

In recent years, there has been an increase in activities related to environmental issues, such as the United Nations' "SDGs," the Ministry of the Environment's "Plastic Smart," and the "Osaka Blue Ocean Vision" adopted by the G20. Under these circumstances, the present applicant has proposed an eco-file made of 100% paper, aiming at environmentally friendly manufacturing and initiatives such as eliminating plastics (see Non-Patent Document 1). This eco-file is attracting attention because it can significantly reduce CO2 emissions during the manufacturing process and disposal compared to plastic files. Most conventional paper files are glued together, but this eco file does not use any auxiliary materials such as glue, bond, or wire, and is crimped using a special crimping technology that will be described later. Compared to files, it has the advantage of reducing CO2 emissions.

"overview"
The paper file in the embodiment of the present invention is an eco-file made of 100% paper that is crimped using a special crimping technique without using any auxiliary materials. Normally, a file is manufactured by folding a sheet of paper in half and binding one side together, but he invented a file made by layering two sheets of paper made of different materials (white paper, Japanese paper, colored paper, etc.). This makes it possible to produce a wide variety of paper files with simple and beautiful designs.

"exterior"
FIG. 1 is a front view of a paper file 1 according to an embodiment of the present invention, in which (A) is an overall view and (B) is an enlarged photograph of a portion W1 thereof. FIG. 2 is a rear view of the paper file 1 shown in FIG. 1, in which (A) is an overall view and (B) is an enlarged photograph of a portion W2 thereof.

In the embodiment of the present invention, as shown in FIGS. 1 and 2, two sheets of paper 10 and 20 made of different materials are used. For example, the front paper 10 is made of beautiful high-quality paper, and the back paper 20 is made of white matte coated paper. The details will be described later, but the lower part of one sheet of paper 20 is folded back to a size that can hold the document, and another sheet of the same size is placed on top of that sheet of paper 20. The left side 11 of 20 is crimped vertically with a binding machine (hereinafter referred to as a binder) and bound. As a result, a line of uneven traces 12 having the same length as the left side 11 is provided to the portion crimped with the binder (hereinafter referred to as the crimped portion), as shown in FIG. 1(B). Similarly, as shown in FIG. 2(B), a line of unevenness marks 22 having the same length as the right side 21 (corresponding to the left side 11 in FIG. 1) is provided on the back side of the paper 20. On the right side of the line of the unevenness mark 12 on the paper 10, which becomes the front surface, a single line 13 having the same length as the left side 11 is placed, as shown in FIG. 1(A). Through this manufacturing process, a paper file 1 with a pocket for holding documents etc. is completed.

《Usage condition》
FIG. 3 is a perspective view showing how the paper file 1 shown in FIG. 1 is used. As shown in FIG. 3, when the front paper 10 is turned over, an outward facing pocket P for storing documents 30 and the like is revealed. As described above, since the papers 10 and 20 made of different materials are stacked one on top of the other, the paper 10 on the front side can be easily turned over, and the contents can be checked immediately. Moreover, since the line 13 is placed on the right side of the line of the unevenness marks 12 on the paper 10 that will become the front side, when the paper 10 that will become the front side is opened from right to left, it will naturally fold back at the line 13. Therefore, no load is applied to the crimping part, making it possible to maintain its strength for a long time.

Currently, most of these types of files are bound at the bottom (the bottom part of the file), so there is a risk that they may tear or peel off when documents are sandwiched between them. In the present invention, since the lower part is made into a pocket P, it is possible to maintain strength even if documents 30 etc. are repeatedly pinched.

《Special crimping technology》
FIG. 4 is a schematic diagram for explaining the principle of the binder used in the embodiment of the present invention. This binder is a small desk type binding machine, and as shown in FIG. 4, it is equipped with a pair of gears 100A and 100B arranged vertically opposite to each other. A plurality of uneven teeth 101A are formed on the outer peripheral surface of the upper gear 100A, and a plurality of uneven teeth 101B are also formed on the outer peripheral surface of the lower gear 100B, and the upper and lower uneven teeth 101A, 101B are positioned so as to mesh with each other. ing. In this schematic diagram, the upper and lower uneven teeth 101A, 101B are simply depicted, but it goes without saying that the shape, number, size, etc. of the upper and lower uneven teeth 101A, 101B can be adjusted as appropriate. When two sheets of paper 10, 20 are overlapped and fed into the gap between the upper and lower uneven teeth 101A, 101B, and the upper and lower gears 100A, 100B are rotated, the two sheets of paper 10, 20 are compressed and sent out. At this time, the other paper 20 (10) enters the stretched portion of one paper 10 (20), and uneven marks 12, 22 are given to the two sheets of paper 10, 20, and the two sheets of paper 10, 20 are designed to stick together only by applying pressure.

"Manufacturing process"
FIG. 5 is a schematic diagram showing the manufacturing process of the paper file 1 in the embodiment of the present invention. Hereinafter, the manufacturing process of the paper file 1 will be explained in more detail with reference to FIG.

First, as shown in FIG. 5(A), high-quality paper is prepared as the paper 10 that will become the front surface, and as shown in FIG. 5(B), streaks 13 are made on the paper 10 that will become the front surface. At this time, the distance L from the left side 11 to the line 13 is set to about 8 mm so that the left side 11 and the line 13 are at equal positions (symmetrical positions) with respect to the line of the uneven trace 12. If the line 13 is too close to the line of the unevenness mark 12, the strength of the crimped portion will be weakened. On the other hand, if the line 13 is too far away from the line of the unevenness mark 12, there is a possibility that the document 30 will protrude from the file when the document 30 is sandwiched.

Next, as shown in FIG. 5C, a different type of paper (for example, matte coated paper) from the paper 10 that will be the front side is prepared as the paper 20 that will be the back side. The size of the paper 20 is made slightly larger than the paper 10. As shown in FIG. 5(D), fold the paper 20 that will become the back side at a position 20a that is approximately one-fourth of the long side, and as shown in FIG. 5(E), turn the paper 20 that will become the back side so that it becomes the front side. Make it the same size as paper 10.

Finally, as shown in FIG. 5(F), overlap the paper 10 that will become the front surface and the paper 20 that will become the back surface, and as shown in FIG. Crimp and bind with a binder. At this time, since the left end of the pocket P can also be bound together, it is possible to manufacture the paper file 1 with a pocket in fewer steps than in the case of adhesive bonding.

"pocket"
FIG. 6 is a schematic diagram for explaining the pocket P of the paper file 1 shown in FIG. As shown in FIG. 6(A), when the paper 10 that will become the front side is lifted and opened from right to left, the paper 10 that will be the front side is naturally folded back along the lines 13 as shown in FIG. 6(B). Can be expanded. As shown in FIG. 6(C), the left end Pa of the pocket P is bound with a binder, and the right end Pb of the pocket P is open. Therefore, by shifting the upper right corner of the pocket P slightly to the lower left corner, documents 30 and the like can be easily inserted and taken out, as shown in FIG. 6(D).

《Types and characteristics of paper》
Next, the types and characteristics of paper will be explained. There are various types of paper in the world, but here we will explain high-quality paper, matte coated paper, and Japanese paper (machine-made).

Matte coated paper is paper whose surface is coated with a coating agent or coating agent. When printed, photos and illustrations become more vivid.

Washi (machine-made) is Japanese paper that is made using a paper machine. The fibers are much longer than Western paper, so they intertwine in various directions, creating complex patterns.

High-quality paper is paper with 100% chemical pulp content and no surface coating. Because it is not coated like coated paper, it has less luster and shine, making it suitable for printed matter that focuses on text or that requires frequent page turning. Wood pulp is mainly used to manufacture high-quality paper, and it is characterized by the fact that ink and other substances easily penetrate into the gaps in the pulp and are easily absorbed.

Note that chemical pulp is pulp obtained by removing lignin etc. from wood using chemicals and extracting cellulose. Depending on the chemicals used, there are sulfite pulp, soda pulp, sulfate pulp, etc. It has higher purity than mechanical pulp and is used for making high-quality paper.

《Paper combination》
As mentioned above, there are a limited number of papers that can be crimped using special crimping techniques. For example, when high-quality paper and high-quality paper are bound together with a binder, both have no surface coating and the fibers are fine, so the binding of the binder becomes loose and the strength of the crimped part is low, making it easy to tear.

Therefore, the present inventor combined various types of paper and tested the strength of the crimped portion. As a result, it was found that binding paper made of a specific material with a binder increases its strength. That is, when high-quality paper and matte coated paper are bound together with a binder, the coating agent on the surface of the matte coat soaks into the high-quality paper by applying the binder, increasing its strength. It was also found that when high-quality paper and Japanese paper (machine-made) are bound together with a binder, the fibers of the Japanese paper (machine-made) become entangled with the high-quality paper and become stronger. Furthermore, it was found that when matte coated paper and Japanese paper (machine-made) are bound with a binder, the coating agent and fibers become entangled, increasing the strength of both.

As a result of the above test, in the present invention, the papers 10 and 20 made of different materials are bonded together using a binder. As a result, the strength of the crimped portion can be ensured even if special crimping technology is used, so paper files 1 with simple and beautiful designs can be manufactured in a wide variety of types.

The advantage of crimping the papers 10 and 20 of different materials with a binder is not only that the strength of the crimped portion is ensured. In other words, white paper (matte coated paper) can be procured at low cost, whereas high-quality paper, especially Japanese paper, is beautiful paper but is extremely expensive and cannot be sold on the market. There are some products on the market, but in order to keep costs down, the paper in many of them is quite thin and lacks durability. In the present invention, costs can be reduced by combining low-cost materials (e.g., matte coated paper) and expensive materials (e.g., high-quality paper) as described above, and paper of appropriate thickness can be used accordingly. can. This invention can be said to be a logical invention that has been devised in terms of materials and manufacturing processes.

《Paper Grain》
FIG. 7 is a schematic diagram for explaining the paper grains G1 and G2 of the paper file 1 shown in FIG. The paper grains G1 and G2 refer to the directions in which the fibers of the paper flow, and FIG. 7(A) shows the horizontal grain, and FIG. 7(B) shows the vertical grain. As shown by the symbol D in FIG. 7, when binding the stacked papers 10 and 20 with a binder, the papers 10 and 20 are fed from the lower end into the gap between the upper and lower uneven teeth 101A and 101B, and flowed toward the upper end. go. At that time, as shown in FIG. 7(A), it was found that when binding with a binder at right angles to the grain G1 of the paper 10 serving as the front surface, the fibers of the paper 10 are less likely to be crushed and the strength is increased. On the other hand, as shown in FIG. 7(B), it has been found that when binding with a binder in parallel to the grain G2 of the paper 10 serving as the front surface, the fibers of the paper 10 are crushed and the strength is reduced. Therefore, in the present invention, the paper 10 is set in the direction shown in FIG. 7(A) and bound so that the line of the uneven marks 12 is approximately perpendicular to the paper grain G1, thereby successfully increasing the strength of the crimped part. are doing.

《Comparison with conventional products》
FIG. 8 is a graph comparing the product of the present invention and the conventional product. As shown in FIG. 8, the polypropylene clear file, the conventional (glue bonded) paper file, and the paper file 1 according to the embodiment of the present invention are classified by "indirect CO2,""duringdisposal," and "during manufacturing." CO2 emissions were compared. As a result, it was found that the paper file 1 according to the embodiment of the present invention can reduce CO2 emissions by about 68% compared to the polypropylene clear file. Also, compared to paper files bonded with glue, it has the advantage of reducing CO2 emissions from auxiliary materials. In recent years, decarbonization and plastic removal activities such as "SDGs", "Plastic Smart", and "Osaka Blue Ocean Vision" have been active, and the product of this invention, which does not use any auxiliary materials such as glue, is extremely environmentally friendly. This can be said to be an invention with high practical value.

《Characteristic configuration of the present invention and its effects》
As explained above, the paper file 1 according to the embodiment of the present invention is constructed by feeding two sheets of paper 10 and 20 between the uneven teeth 101A and 101B, and inserting the two sheets of paper between the meshing uneven teeth 101A and 101B. A paper file 1 is manufactured using a binder that compresses and sends out papers 10 and 20, and the papers 10 and 20 are made of different materials for the front paper 10 and the back paper 20. It is characterized in that the sheets 20 are overlapped and the left sides 11 of the overlaid sheets 10 and 20 are bound with a binder. In this way, when the papers 10 and 20 made of different materials are compressed and bound together with a binder, they are strong, so it is possible to provide a wide variety of paper files 1 without using auxiliary materials.

In addition, a line of uneven marks 12 is formed on the surface paper 10 from the upper end to the lower end of the left side 11, and on the inside (right side) of the line of the uneven marks 12, there is a line from the upper end to the lower end of the left side 11. It is desirable that 13 be included. Thereby, even if the left side 11 is firmly crimped from the upper end to the lower end with the uneven traces 12, the left side 11 can be easily folded back at the position of the line 13 from the upper end to the lower end. Therefore, the paper 10 serving as the front side can be turned over like a notebook, and the documents 30 etc. inserted inside can be easily checked. In addition, the stripes 13 serve to make it difficult to apply a load to the crimped portion when the paper 10 that becomes the front surface is turned over, and has the advantage of making the strength of the crimped portion last longer.

Further, it is preferable that the binding is performed such that the line of the unevenness marks 12 is approximately perpendicular to the grain of the paper 10 serving as the front surface. This makes it difficult for the fibers of the paper 10 to collapse, making it possible to further increase the strength of the crimped portion.

Further, it is preferable that a pocket P is formed at the bottom of the paper 20 by folding back the lower part of the paper 20, which will become the back side, and stacking the folded part together with the paper 10 and binding with a binder. This makes it possible to maintain strength compared to the case where the lower part of the file is bound with a binder. Since the paper 10 serving as the front surface can be turned over like a notebook, there is also the advantage that documents 30 and the like can be easily held in the inner pocket P.

Further, it is desirable that the paper 10 serving as the front side is a paper without a surface coating, and the paper 20 serving as the back side is a paper having a surface coating. As a result, when the paper 10 and the paper 20 are pressure-bonded with a binder, the coating agent on the surface of the paper 20 soaks into the paper 10 by applying the binder, thereby increasing the strength.

Further, it is desirable that the paper 10 serving as the front surface is high-quality paper, and the paper 20 serving as the back surface is matte coated paper. This makes it possible to reduce costs by combining low-cost and high-priced materials, and to use paper of appropriate thickness.

《Other embodiments》
As described above, the embodiments of the present invention have been described, but the statements and drawings that form part of the disclosure are illustrative and should not be understood as limiting. Various alternative embodiments, implementations, and operational techniques will be apparent to those skilled in the art from this disclosure.

For example, in the above description, a combination of high-quality paper and matte coated paper was exemplified as the papers 10 and 20 made of different materials, but the present invention is not limited to this. For example, other combinations such as Japanese paper and matte coated paper, Japanese paper and bamboo paper, Japanese paper and high-quality paper, etc., may be used as long as they can ensure the strength of the crimped portion. However, considering the fact that paper of appropriate thickness can be used while reducing costs, a combination of high-quality paper and matte coated paper is most desirable.

Furthermore, in the above description, the paper file 1 is illustrated in which the papers 10 and 20 made of different materials are pressed together with a binder, but it is also possible to bond the papers 10 and 20 made of different materials together with glue or the like. In this case, it goes without saying that lines 13 may be provided along the bonded portion. As a result, no load is applied to the bonded portion, and its strength can be extended for a long time. However, if you are concerned about the environment, it is recommended to use a binder to bond the parts rather than using glue (see Figure 8).
