[Technical field to which the invention belongs]
The present invention relates to a binding tool used when a plurality of sheets or documents are perforated and bound, and is provided with a comb member, a hole for passing the comb member, and a retaining groove for fixing the comb member. And a file binding device comprising a combination of
[0002]
[Prior art]
The file binding device is used by inserting a clip or a paper or document into a hole, and inserting a ring-shaped nail or stick-shaped comb (sometimes called a fastener) into the hole. There was something to do. Generally, a binding tool to be used by inserting and inserting a ring-shaped claw member or a stick-shaped comb member is a metal or synthetic resin used for the claw member or the comb member.
[0003]
[Problems to be solved by the invention]
By the way, when discarding old filed documents as garbage, a conventional metal or synthetic resin binding device cannot be incinerated together with combustible materials such as paper. That is, there is a problem that the metal portion remains unburned when incinerated as it is with the old file. On the other hand, a plastic portion such as PVC generates a harmful gas or a bad smell, which is a problem in garbage disposal. Therefore, it is necessary to remove metal parts and synthetic resin parts for disposal, and the separation process is required. However, since the separation process is performed manually, it takes time and labor, and there is a risk that the finger may be damaged by the sharp tip. there were.
[0004]
Furthermore, with the recent rise in environmental pollution prevention and paper recycling campaigns, attempts have been made to reuse used filed paper as used paper. It is necessary to separate the binding device, which is laborious and expensive as described above.
On the other hand, conventional binding devices have various materials, such as metal, plastic, and metal coated with plastic. Furthermore, the amount of paper is smaller than that of removed paper, making it difficult to reuse and not suitable for recycling.
Therefore, when processing an old file that has been used, the need to separate the file binding device has been eliminated, the file binding device can be incinerated as it is, or the file binding device has been buried in the soil. At times, conversion to materials that do not decompose and cause garbage pollution problems is demanded.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and the purpose of the present invention is not to form a file binding device from a metal or synthetic resin member as in the related art, but to perform a sorting process. It is made of an organic fibrous material in consideration of the safety of handling and the requirement of preventing environmental pollution. It is an object of the present invention to provide a binding device for a file which can be incinerated or landfilled together with general paper waste as it is.
[0006]
Further, a binding device using a stick-shaped comb member adds an operation of repeatedly bending the comb member each time a document is punched and bound. Therefore, it is a second object of the present invention to provide a binding tool which is less likely to be broken even when repeatedly bent, and has excellent folding resistance.
[0007]
[Means for Solving the Problems]
The file binding device of the present invention is formed of a sheet mainly composed of an organic fibrous material (cellulose) as described above. The main material of this sheet is vulcanized fiber (glued fiberboard), which is sometimes simply referred to as fiber.
As is well known, vulcanized fiber is formed by, for example, making cotton pulp or wood pulp into raw paper without any size, laminating the raw paper, and immersing the raw paper in a concentrated solution of zinc chloride (generally a degree of Baume of 65 to 74). This is a tough sheet obtained by subjecting the vegetable fibers of the raw paper to surface swelling (collagenization) with zinc chloride, followed by pressing, removing zinc chloride by washing with water, winding and drying. Incidentally, the moisture contained in the dried sheet is usually 7 to 9%. The obtained product has high elasticity and rigidity, is much lighter than metal, and has high resistance to various oils. If left in a humid atmosphere, the sheet absorbs moisture and becomes soft. In addition, when a predetermined portion is bent in a state where the flexibility remains in the sheet, a three-dimensional shape can be given. When dried while maintaining the shape at the time of molding, the shape at the time of bending and molding is maintained after drying, and the formed sheet becomes rich in impact resistance with rigidity and elasticity unique to Vulcanized Fiber. However, if an excessive force is applied to the sheet in a dry state and the sheet is bent, the sheet may be broken or cracked. As described above, it has been found that the moisture contained in the fiber is closely related to its plasticity (softening).
[0008]
The present inventor furthered the research, and when the fiber was impregnated with glycerin in the above drying process and finished, the impregnated glycerin exhibited moisturizing and absorbing properties, and even if the moisture content of the fiber was constant, the softener was softened. It was confirmed that it exhibited the performance as. Furthermore, in order to exhibit such characteristics effectively and constantly, if the thickness of the fiber and the concentration of glycerin are within a certain range, it is bent like a conventional metal or synthetic resin comb member. They realized that a stick-shaped comb member that would not break or crack even if repeatedly bent and deformed each time a document was bound was obtained, and the present invention was completed as a result of experiments.
[0009]
That is, the first aspect of the present invention is a binding tool used when a plurality of sheets or documents are perforated and bound, and a stick-like comb member, a hole through which the comb member passes, and a fastening member for fixing the comb member. It consists of a combination with a patch plate with a groove,
The stick-shaped comb member has a thickness in the range of 0.3 to 1.2 mm, and imparts moisture retention and moisture absorption by impregnating the fiber with a humectant represented by glycerin in the fiber manufacturing process. A file binding device characterized by being formed from the obtained moisturized vulcanized fiber.
In order to use the moisturized vulcanized fiber as a stick-like comb member, it is essential that the thickness be 0.3 to 1.2 mm. If it is less than 0.3 mm, the bending workability is good, but there are technical problems in fiber production including rigidity and strength, which is not suitable. On the other hand, if the thickness is more than 1.2 mm, the desired bending performance cannot be obtained at the time of use, and it is difficult to deform the file at the time of use.
[0010]
A second aspect of the present invention is characterized in that, in the first aspect, the stick-shaped comb member is adjusted to have a humectant content of 5 to 15%. That is, if the fiber contains the humectant in this range, it has sufficient bending workability as a stick-shaped comb member even if the moisture content is constant as described above, and it is confirmed that it is suitable for practical use. Then, the optimal conditions were achieved for the purpose. If the humectant content exceeds 15%, there is a drawback that the material becomes extremely soft and loses mold holding properties. On the other hand, if it is less than 5%, the bending property required for use as a stick-shaped comb member cannot be obtained, and it becomes difficult to deform the fiber by correspondingly deforming it, resulting in lack of practicality. Not suitable.
[0011]
A third feature of the present invention is that the backing plate is formed of paper or general vulcanized fiber.
[0012]
[Embodiment of the invention]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiment, a two-hole storage paper file will be described, but the present invention is not limited to this embodiment.
[0013]
FIG. 1 shows a paper file as a first embodiment. The paper file 1 includes left and right door covers 2 and 3 with a spine 4 therebetween and a gusset 5 inside the spine. Reference numeral 6 denotes a binding device of the present invention, which is a combination of a stick-like comb member 7 and a backing plate 8 provided with a hole through which the comb member passes and a retaining groove for fixing the comb member. . Reference numeral 9 indicates a document to be stored.
As shown in FIG. 3, the binding device 6 is composed of a stick-like comb member 7 and a backing plate 8 provided with a hole for passing the comb member and a retaining groove for fixing the comb member. The comb member 7 is formed of thin paper made of vulcanized fiber, as described later, and is cut into a long band in the lateral direction of the paper to form a band. The tip is rounded so as not to hurt your hand. The reason why the paper was cut in the horizontal direction is that, as is clear from the table below, the breaking strength is superior to that in the vertical direction.
The backing plate 8 is preferably made of paper or vulcanized fiber mainly made of the same organic fibrous material (cellulose) as the comb member, because it is unnecessary to separate the disc when discarded. This backing plate is formed in a strip shape slightly shorter than the comb member, and is provided with a hole 10 through which the comb member passes and a retaining groove 11 for fixing the comb member outside the hole 10 at the center. Although not shown, the number of holes 10 and grooves 11 provided in the backing plate need not be two, and the number of holes is arbitrary.
[0014]
Here, the use of the binding device is briefly described. Both ends of the comb member 7 (hereinafter, referred to as feet) are passed through the back of the gusset 5 to stand up, and then the feet are opened in a document to be bound. The document is passed through the hole, and the patch 8 is placed on the top of the document. Then, the foot of the comb member is passed through the hole 10 provided in the backing plate 8, the foot is opened outward and bent, and the foot is inserted into the retaining groove 11 provided in the backing plate 8 so as to be hooked from the side. 1 and 2 show the state after insertion.
Note that the stick-shaped comb member 7 of this embodiment has a length of 400 to 200 mm as an example according to the binding amount of the document required for the paper file 1, and a width that is large enough to enter a hole formed in the document. It is about 5 mm. The thickness is a band shape of 0.5 mm. On the other hand, the backing plate 8 is formed to have a length of 16 mm and a width of 17 mm.
[0015]
The stick-shaped comb member 7 is produced under the same manufacturing conditions as those of a conventionally known ordinary fiber, but uses a glycerin-treated fiber in a fiber drying step. By the way, when glycerin is used as an example, a 20% aqueous solution is used, and the raw sheet is impregnated between the dryers and then dried and finished. As a result, the bending strength of the fiber sheet is remarkably improved as shown in the measurement results in the following table. You.
[0016]
[Table 1]

[0017]
The stick-shaped comb member 7 of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, as a humectant other than glycerin, polyhydric alcohol-based polyethylene glycol (PEG) or polypropylene glycol (PPG) can be used.
[0018]
[Effect of the invention]
As described above, the stick-shaped comb member made of vulcanized fiber impregnated with the humectant of the present invention retains flexibility due to the humectant's hygroscopicity and moisturizing property even when left indoors for a long time. Thus, it is possible to provide a binding tool which is easy to bend and has excellent breaking resistance.
Therefore, even if an operation of repeatedly bending the comb member each time a document is bound is added, it is rare that the stick-shaped comb member is broken and becomes unusable. The smooth surface makes it feel good and does not hurt your fingers.
[0019]
When disposing of the old filed documents as garbage, the binding device of the present invention can be easily discarded together with the old documents without being separated after use and incinerated. Therefore, an excellent effect of being safe, adapting to recent environmental problems, and having good disposability is obtained.
[0020]
Further, the present invention has an effect that it can be mass-produced almost in the same manner as ordinary fibers and can be provided at low cost.
