Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper binding tool, and more particularly to a structure for binding a notebook or the like with a paper binding tool and a method for fixing the binding tool.
[0002]
[Prior art]
As a structure to bind paper such as documents like a booklet, there are things by thread or by adhesion, but there are members made of metal or synthetic resin like a spring, so-called spiral ring that binds paper is there.
[0003]
Briefly explaining its structure, about 20 holes are formed inside one side edge of paper such as documents, and many papers can be bound by passing a spiral ring through these holes. It is. When bound in this way, the paper can be rotated 360 degrees without difficulty, so there is no crease and it is convenient to use.
[0004]
On the other hand, when such a notebook using a spiral ring is discarded, it is necessary to separate it into a metal part and a paper part from the viewpoint of waste separation processing and resource recycling.
[0005]
However, it is extremely troublesome to separate what has been bound so that it does not easily come off, and it cannot be denied that it tends to be discarded inappropriately.
[0006]
In view of this, all the combustibles, especially papers that generate less harmful substances during combustion, constitute a booklet that enables integrated processing for paper recycling and incineration.
[0007]
FIG. 4 shows a notebook composed entirely of paper from this point of view. In the figure, a large number of perforations 11 are provided at the edge of the paper 10 to be bound, and the paper is bound by inserting a paper spiral ring 12 through one end of the perforation 11 while rotating it. .
[0008]
In this way, notebooks, calendars, and the like can be completed with only combustible materials with little generation of harmful substances, so that they can be processed without trouble during disposal or recycling.
[0009]
[Problems to be solved by the invention]
However, when the spiral ring is formed of paper as described above, there is a problem due to its material.
[0010]
That is, as shown in FIG. 5, fuzz 14 is generated at both ends of the spiral ring 12. This is considered to occur because both ends of the spiral ring 12 are rubbed as the booklet is opened and closed, and the fibers at the ends that are originally formed of paper and have low strength are separated.
[0011]
In order to prevent this, a method is conceivable in which the tip portion of the spiral ring 12 is hardened with an adhesive or a synthetic resin, and further bent. However, such a method not only complicates the manufacturing process, but also makes it difficult to handle because the tip of the spiral ring that has been processed is sharply pointed, and breakage of the tip is likely to occur.
[0012]
Further, since the spiral ring 12 is rotatably attached, there is a problem that the winding is loosened with aging.
[0013]
The present invention has been made to solve such a conventional problem, and is capable of preventing fuzz and breakage at the tip of the spiral ring with a simple configuration, and also prevents the winding from loosening and a fixing method thereof. It is a technical challenge to provide
[0014]
[Means for Solving the Problems]
The paper binding tool of the present invention is configured as follows in order to solve the technical problems described above.
[0015]
That is, a paper binding tool used when a plurality of paper pieces are stacked and bound together, and a spiral ring formed by spirally forming a linear organic fibrous material is inserted into a perforated portion formed in the paper piece. And binding both ends of the spiral ring to a cover portion located on the outer surface of the paper piece.
[0016]
As the spiral ring, a spiral-shaped member made of vulcanized fiber can be used.
[0017]
In addition, when bonding both ends of the spiral ring so as to cover the sheet body, a sheet body having an adhesive layer is bonded to both ends of the spiral ring, and the sheet body is bonded to the cover portion located on the outer surface of the piece of paper. Thus, a method of fixing both end portions of the spiral ring to the cover portion can be adopted.
[0018]
The second invention uses a spiral ring formed by spirally forming a linear body made of an organic fibrous material and a paper piece having a plurality of perforated portions, and the paper piece is bound by inserting the spiral ring into the perforated portion. In addition, a sheet body having an adhesive layer is bonded to both end portions of the spiral ring, the sheet body is bonded to a cover portion located on the outer surface of the paper piece, and both end portions of the spiral ring are fixed to the cover portion. This is a method of fixing the paper binding tool.
[0019]
Also in this case, the spiral ring can be a spiral member made of a vulcanized fiber.
[0020]
Hereinafter, each part will be briefly described.
[Spiral ring]
As the spiral ring, an organic fibrous material made of wood pulp or the like, for example, a spiral member formed by chopping vulcanized fiber is used. That is, a raw material of vulcanized fiber is cut into a linear body, and a plurality of paper pieces can be stacked and bound together by a spiral ring formed into a spiral shape.
[Vulcanized fiber]
It is manufactured from various organic fibers having properties similar to those of wood pulp and paper, such as cotton rug. The manufacturing method is formed by immersing these fibers in a concentrated solution of zinc chloride, compressing and integrating them to a certain plate thickness using the swelling gelatinization reaction of the solution to the fibers, washing with water after aging and drying. It is an organic industrial material, has a high tissue density, is tough and hard to wear, is chemically neutral and excellent in oil resistance, and is non-magnetic, and added with pigments and dyes to raw paper By doing so, it can be colored in various colors.
[0021]
In addition, vulcanized fiber has a processability that is easy to mold when heated, and has a property that a shape at the time of molding is fixed when cooled as it is.
[0022]
More specifically, the above-mentioned rod-shaped member is supplied in a heating atmosphere maintained at a heating temperature of 80 to 160 degrees, and the moisture content of this rod-shaped member is maintained at 7 to 10%. In addition, when the moisture content is 6% or less, the elasticity becomes low and becomes brittle.
[0023]
Then, immediately after the rod-shaped member is wound around the cored bar for molding, the molded cored bar is advanced to the front while rotating at a constant speed, and then the bar-shaped member is formed into a spiral shape with a predetermined pitch. Then, the temperature of the cord-like member is lowered and fixed in a spiral shape, and then cut into a predetermined length to obtain a spiral ring.
[0024]
In consideration of practicality, the member having a thickness of 0.5 mm or more and 2.00 mm or less, preferably 0.8 mm or more and 1.3 mm or less is suitable. The width is 1.0 mm or more and 3.0 mm or less, preferably 1.5 mm or more and 3.0 mm or less. The density is 0.8 g / cm 3 or more and 1.5 g / cm 3 or less, preferably 1.1 g / cm 3 or more and 1.4 g / cm 3 or less. The bending strength is 140 MPa to 200 MPa in the vertical direction, 90 MPa to 130 MPa in the horizontal direction, and the average moisture content is 7% to 12%, preferably 7% to 10%. A deformation temperature of 80 to 160 degrees is suitable for use.
[0025]
In addition, the coating which contributes to antifouling, waterproofing, and aesthetics by protecting this on the surface of the spiral ring 1 can be applied.
[0026]
As a method for this, a polyolefin resin such as polyethylene or polypropylene is melt-extruded and laminated on a plate-like vulcanized fiber. Or hot melt type resin made of polyolefin resin or polyester resin. Furthermore, there are various methods for applying and drying emulsions and solutions such as waxes and polyvinylidene chloride resins.
[Paper piece]
Examples of paper made of pulp include notebooks and calendars.
[Cover part]
Of the paper pieces, the paper is located on the outermost surface of the uppermost part and the lowermost part, and can be formed with thicker paper than other paper pieces 2 in order to obtain strength in a notebook or the like, but it is not necessarily required to be thick paper. . Moreover, although the paper located in the lowest part among the paper pieces 2 is generally called a back cover, the concept is the same as that of the cover in the sense that the paper is exposed on the surface. Accordingly, the concept of adhering both ends of the spiral ring to the back cover is naturally included.
[Both ends]
Although it is the cutting part of the spiral ring 1, it is desirable to form this part linearly. This straight line portion is used as a bonding allowance for the cover portion 3 and is used for more reliable bonding. The length of the straight portion is preferably about 1 cm to 3 cm. Even in the case where it is not formed linearly, it is possible to forcibly bring it into a flat state by adhering the curled portion while crimping.
[Sheet body]
It fixes both ends of the binding member to the cover, and is formed of paper or an incineration cloth. Further, the size has a width and length enough to cover both ends of the spiral ring. Specifically, it is preferably about three times the width of the spiral ring and about 1.5 times the length of the plane portion.
[Adhesive layer]
It is composed of an adhesive layer or an adhesive. Examples of the adhesive layer include those previously applied to a sheet body, the surface of which is protected in advance with a fluorine-coated paper or the like, and the fluorine-coated paper is peeled off during use.
[0027]
Moreover, when using an adhesive agent, a synthetic rubber-type adhesive agent can be illustrated and you may make it apply | coat to the sheet | seat body 5 each time it adhere | attaches.
[Perforated part]
A large number of holes are provided inside the edge of the paper piece, and are usually rectangular (or round) holes.
[0028]
As described above, since both ends of the spiral ring are bonded to the cover portion, there is no fear of fluffing and the like, and it can be used comfortably. Further, since both ends of the spiral ring are fixed to the cover portion, the winding of the spiral ring is not loosened, and the overall strength can be ensured and the appearance is good.
[0029]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the vulcanized fiber paper binding tool of the present invention will be described in more detail with respect to the embodiment shown in FIGS.
[0030]
The figure shows an example implemented in a notebook, in which a large number of paper pieces 2 are stacked and bound together by a paper spiral ring 1.
[0031]
The spiral ring 1 is formed by spirally forming a vulcanized fiber-like member, and the paper piece 2 is passed by passing the spiral ring 1 through about 20 perforations 7 formed inside the side edge of the paper piece 2. It is bound. When passing the spiral ring 1 through the perforated part 7, the tip of the spiral ring 1 is passed through the perforated part 7 located at the end, and the spiral ring 1 is rotated to be sequentially inserted into the perforated part 7. The rotation of the spiral ring 1 is stopped at the time when it passes through.
[0032]
Subsequently, both end portions 4 of the spiral ring are formed into a straight line of about 3 cm as shown in FIG. 2, and the straight portions are covered with a sheet body 5 having an adhesive layer 6 on the cover portion 3 of the paper piece as shown in FIG. Glue so that.
[0033]
When forming both end portions 4 of the spiral ring in a straight line, it may be formed by squeezing by hand, or a jig may be used. As a jig, there is a jig in which a semicircular mold that meshes with each other is provided at the tip of a pliers, and both ends 4 are formed in a straight line by sandwiching both ends 4 with this mold.
[0034]
In this case, a heater is built in the portion that sandwiches both end portions 4 of the spiral ring, and heating to about 80 to 160 degrees makes it easier to form a straight line and reduces the return of winding. It can be formed into a stable shape.
[0035]
When adhering the both end portions 4 thus straightened to the cover portion 3, the both end portions 4 are adhered to the same cover portion 3 as shown in FIG. That is, although there are two front and back sheets on the front cover, it is not desirable to bond both end portions 4 to different front covers. This is because when the both end portions 4 are bonded to another cover, the front and back cover portions 3 are elastically connected via the spiral ring 1 and resistance and urging are generated when the cover is opened and closed. Therefore, it is necessary to adhere both end portions 4 to one of the front cover and the back cover.
[0036]
In addition, the both ends 4 of the spiral ring are bonded to the cover portion 3 so that both ends 4 are covered with the sheet body 5. First, the sheet body 5 having the adhesive layer 6 on both ends 4 of the spiral ring 1. It is efficient to adhere the sheet body 5 to the cover portion 3 located on the outer surface of the paper piece 2. The sheet body 5 may be formed in a rectangular shape, but if it is formed in a semicircular shape as shown in FIG.
[0037]
As described above, since the booklet can be composed entirely of paper products, it can be incinerated as it is even after being used as a notebook or calendar, and of course, both ends 4 of the spiral ring are not exposed. No fluffing or breakage occurs. In addition, since it does not expose in the state where both ends 4 are sharp, it is preferable from the viewpoint of safety.
[0038]
Further, since the sheet body 5 adheres the both end portions 4 of the spiral ring to the cover portion 3, the manufacturing is extremely easy.
[0039]
【The invention's effect】
According to the present invention, a paper ring is bound by passing a spiral ring made of an organic fibrous material through a perforated portion formed in a predetermined number of the paper piece, and both ends of the spiral ring are bonded to a cover portion located on the outer surface of the paper piece. Therefore, since both ends of the spiral ring are not exposed, both ends of the binding member are not damaged by fuzzing or breaking.
[0040]
Moreover, since the spiral ring is fixed to the cover part, the booklet can be used comfortably without fear of the winding being returned.
[0041]
In addition, since it is easy to manufacture, it can be implemented at low cost.
