Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper fastener reinforcing sheet for fixing a paper fastener used for filing a document to a file mount.
[0002]
[Prior art]
Conventionally, as a binding tool for easily filing documents, a paper fastener 1A including a single plate-like member 2 as shown in FIG. As a method of using the paper fastener 1A, first, the paper fastener 1A is bent into a U shape ((b) in the same figure), and then the band metal fitting 3 of the paper fastener 1A is attached from the back surface of the file mount 10 having the through hole 11. It passes through the through hole 11 ((c) in the figure). Then, the document is filed by fitting the through hole 13 of the document 12 to the band metal 3, and the upper part of the band metal 3 protruding from the upper surface of the document is bent outward or inward along the upper surface of the document 12. As a result, the document 12 is fixed to the file mount 10 to form a file ((d) ₁ , (d) _{2 in} the figure).
[0003]
As such a paper fastener, one in which an adhesive layer 4 and a release paper 5 are sequentially provided on one side of a plate-like member 2 is used as in a paper fastener 1B shown in FIG.
[0004]
Further, as shown in FIG. 18A, a paper fastener 1C composed of a fastener body 1 composed of a plate-like member 2 and a band bracket 3 and a fastener 6 is also widespread. As shown in FIG. 2B, the paper fastener 1C is used by passing the band metal 3 of the fastener body 1 from the back of the file mount 10 through the through-hole 11 of the file mount 10 and the through-hole of the document 12 as shown in FIG. Although it is the same as the paper fastener 1A described above in that the document is filed by being attached to the strap 3, when the document 12 is fixed to the file mount 10, the fastener 3 of the fastener body 1 is attached to the fastener 6. As shown in FIG. 7C, the band metal 3 is fixed by sliding it through the through hole 7 and bending the clamp 8 of the metal clamp 6 to slide it.
[0005]
There is also a paper fastener using the fastener 6 in which an adhesive layer and a release paper are sequentially provided on the back surface of the plate-like member 2 (the surface on which the fastener is not fitted) (see Patent Document 1). As shown in FIG. 19, the paper fastener 1D provided with the adhesive layer 4 on the plate-like member 2 does not require a through hole in the file mount 10 and fixes the fastener body to the filing surface of the file mount 10 with the adhesive layer 4. .

[Problems to be solved by the invention]
However, in the conventional paper fastener, a type in which the band metal fitting 3 is used by passing it through the through hole 11 of the file mount 10, as shown in FIG. 16, has a plate-like shape on the back surface of the file mount 10 of the produced file. Since the member 2 is exposed, there is a problem that the plate-like member 2 is caught when the files are arranged on a document shelf or the like and put in and out.
[0008]
On the other hand, in the type in which the adhesive layer 4 is provided on the back surface of the plate-like member 2 and the paper fastener is fixed to the file mount 10 with the adhesive layer 4, the paper fastener is easily peeled off from the file mount 10 due to the weight of the filing paper. There's a problem.
[0009]
On the other hand, in the present invention, even if the paper fasteners 1A and 1C do not have the adhesive layer 4 on the back surface of the plate-like member 2, the plate-like member 2 is not exposed on the back surface of the file mount 10 and is strong. Paper fastener can be fixed to the filing surface of the file mount, and after using the paper fastener for filing, a paper fastener reinforcement sheet is provided that makes it easy to remove the paper fastener from the file mount and reuse it easily. The purpose is to do.
[0010]
[Means for Solving the Problems]
The present inventor attaches the sheet fastener having the adhesive layer on one side to the file mount so as to cover the plate-like member of the paper fastener placed on the filing surface of the file mount from above, and attaches the paper fastener to the file mount. It can be firmly fixed, and if a slit extending in the longitudinal direction of the paper fastener is formed in the sheet area located on the plate member of the paper fastener, the paper fastener is removed from the used file and separated and collected. When you do this, you can easily remove the paper fastener from the file mount by pulling up the paper fastener that is fixed to the file mount diagonally upward, and even if you make a slit in the sheet like this, filing the document Secure the paper fastener to the file mount with sufficient strength Kill it, further, the formation of the slit, or attached piece of sheet in a paper fastener when removing the paper fasteners from the file mount, found that it is possible to prevent the cluttering around.
[0011]
That is, in the present invention, a surface sheet, an adhesive layer, and a release sheet are sequentially laminated, and two through holes for passing a band fastener of a paper fastener are opened in the surface sheet, and the two through holes are formed between the two through holes. Provided is a paper fastener reinforcing sheet in which a central slit or cut extending in a direction connecting two through holes is formed.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.
[0013]
FIG. 1: is the front view (a), sectional drawing (b), and rear view (c) of the paper fastener reinforcement sheet | seat 100A of one Example of this invention.
[0014]
This paper fastener reinforcing sheet 100A has a layer structure in which an adhesive layer 30 and a release sheet 40 are sequentially laminated on the entire back surface of the top sheet 20.
[0015]
The surface sheet 20 is preferably formed from an easily tearable sheet material that can be torn in a certain direction. For example, a cloth cloth, an easily tearable resin sheet, an easily tearable nonwoven fabric, or the like can be used. . In particular, the cloth cloth is tearable and strong, and after the paper fastener is fixed with the paper fastener reinforcing sheet 100A, when the used paper fastener is removed, chips of the surface sheet are attached to the paper fastener. It is also preferable in that it is difficult to adhere.
[0016]
The outer shape of the topsheet 20 is a trapezoid with rounded corners. Normally, in the production of a file, the center of the through hole 13 of the document 12 is located at a distance of 10 to 20 mm from the central broken line 10c of the file mount 10 (see FIG. 15), so the through hole of the paper fastener reinforcing sheet 100A When 21 is also attached to the file mount 10, the center of the through hole 21 is usually positioned at a distance D1 of 10 to 20 mm from the central broken line 10c of the file mount (FIG. 2 (c)). The area S1 of the surface sheet 20 that supports the paper fastener 1A on the side of the central broken line 10c with respect to the through hole 21 (the area painted with fine dots in FIG. 2C) is the surface sheet 20 that supports the paper fastener 1A on the opposite side. Is smaller than the area S2 (region filled with coarse dots in FIG. 2C). On the other hand, the area S1 can be increased by making the topsheet 20 trapezoidal.
[0017]
Further, by rounding the corners of the topsheet 20, it is possible to prevent the paper fastener reinforcing sheet 100A from being peeled off from the corner after the paper fastener reinforcing sheet 100A is attached to the file mount.
[0018]
The size of the top sheet 20 is at least a size that completely covers the plate member of the paper fastener, but the length L1 of the bottom side of the trapezoid is 120 to 150 mm and the upper side from the viewpoint of the fixing strength of the paper fastener to the file mount. The length L2 is preferably 100 to 130 mm. Further, as described above, the center of the through hole 21 is located at a distance D1 of 10 to 20 mm from the central broken line 10c of the file mount, and accordingly, the side (trapezoid) of the topsheet 20 on the central broken line 10c side of the file mount. When the distance between the base 20a and the center of the through hole 21 is made slightly smaller than the distance D1, the distance L4 between the side 20a and the central slit 22 and the side opposite to the side 20a (the upper side of the trapezoid) 20b The distance L5 between the center slit 22 and L5 / L4 is preferably 3 or more from the viewpoint of the fixing strength of the paper fastener. On the other hand, the width L7 of the central slit 22 is preferably 0.8 to 1.2 mm as will be described later. The distance (trapezoidal height) L3 between the sides 20a and 20b is preferably 43 to 80 mm.
[0019]
The through-hole 21 is opened to allow the above-described known paper fasteners 1A to 1D of the band fitting 3 to pass through. The planar shape of the through hole 21 is a rectangle with rounded corners, as shown in the broken line frame in FIG. If it is circular, the band 3 is easily rattled by the dead weight of the document 12 that has been filed. Further, if the rectangle is not rounded, the through-hole 21 is easily torn by the force applied to the band fitting 3. The width L6 of the through hole 21 is preferably 5 to 7 mm.
[0020]
Between the two through-holes 21, it extends in a direction connecting the two through-holes 21 (that is, a longitudinal direction of the paper fastener in a state where the pair of band fasteners 3 of the paper fastener is passed through the two through-holes 21). The straight central slit 22 is formed without communicating with the through hole 21.
[0021]
In the present invention, in place of the central slit 22, a notch whose width L7 is eliminated may be provided. However, when removing the paper fastener from the file mount of the used file and reusing the paper fastener, the surface sheet 20 or the adhesive layer is used in order to suppress as much as possible that a piece of the surface sheet or adhesive remains on the paper fastener. Although it depends on the 30 materials, it is generally preferable that the width L7 of the central slit 22 is 0.8 mm or more. Moreover, since the force which presses a paper fastener will become weak and the fixing strength of a paper fastener will become weak too much when the width | variety of the center slit 22 is too wide, it is preferable to set it as 1.2 mm or less.
[0022]
The length L8 of the central slit 22 is preferably 66 to 70 mm, which is slightly shorter than the distance between the two through holes 21. In the present invention, the central slit 22 may be communicated with the through hole 21, but it is preferable that the central slit 22 is not communicated from the viewpoint of further increasing the fixing strength of the paper fastener.
[0023]
In the vicinity of both end portions 22 a of the central slit 22, a long end slit 23 and a short end slit 24 are shaped like a letter C, and the narrower interval between the end slits 23, 24 is the central slit 22. It is formed toward the end 22a. Here, the short end slit 24 is located between the end 22a of the central slit 22 and the through hole 21, and its length L9 is preferably 2.5 to 3 mm. On the other hand, the long end slit 23 has a central slit side end 23a closer to the central slit 22 than the central slit side end 24a of the short end slit 24, and has a length L10. Is preferably 6.5 to 7.5 mm.
[0024]
Further, as described above, in the vicinity of both end portions 22 a of the central slit 22, the long end slit 23 and the short end slit 24 that are formed in a letter C shape are pointed around the central portion of the central slit 22. It is formed symmetrically.
[0025]
By forming the central slit 22 and the C-shaped end slits 23 and 24 in this way, the used paper fastener can be smoothly removed from the file mount as will be described later.
[0026]
In addition, in order to make it easy to remove the used paper fastener from the file mount, unlike the paper fastener reinforcing sheet 100X shown in FIG. 14, the central slit 22 or the notches and the end slits 23 and 24 are not formed. It is also conceivable to form a cut 25 in the top sheet 20. When formed in this way, a part of the surface sheet 20 can be peeled off from the cut 25, and the paper fastener can be removed from the file mount, but the sheet flakes or adhesive layer easily adheres to the paper fastener, and has been peeled off. It is not preferable because the sheet waste is easily scattered.
[0027]
On the other hand, the adhesive layer 30 is preferably provided with an adhesiveness of about 1.1 to 1.7 kgf / 25 mm. The pressure-sensitive adhesive layer 30 may be formed by applying a pressure-sensitive adhesive composition such as an acrylic pressure-sensitive adhesive on the top sheet 20, or using a pressure-sensitive adhesive layer of a double-sided pressure-sensitive adhesive sheet based on a nonwoven fabric or the like. Good.
[0028]
The release sheet 40 is peeled and removed when the paper fastener reinforcing sheet 100A is fixed to the file mount.
[0029]
The release sheet 40 may be formed from a single sheet. For example, as shown in FIG. 1C, when the release sheet 40 is formed from a plurality of sheets 40a and 40b, the release sheet 40 is peeled and removed. When the fastener band 3 is passed, first, the release sheet 40a having the through hole 21 is peeled and removed, but the release sheet 40b having no through hole 21 is left, and the remaining release sheet 40b is gripped. Thus, the band metal fitting 3 can be completely passed through the through hole 21, and then the remaining release sheet 40b can be peeled off, so that the usability of the paper fastener reinforcing sheet 100A is improved.
[0030]
As a method for using the paper fastener reinforcing sheet 100A, for example, when fixing the paper fastener 1A shown in FIG. 15 to the file mount 10, first, the paper fastener 1A is bent into a U-shape and the paper fastener reinforcing sheet 100A is passed through. The release sheet 40a having the hole 21 is peeled and removed, the band metal 3 of the paper fastener 1A is passed through the through hole 21 (FIG. 2 (a)), and the remaining release sheet 40b is also peeled and removed. Is superimposed on the adhesive layer of the paper fastener reinforcing sheet 100A (FIG. 2B). Then, a paper fastener reinforcing sheet 100A is attached to the filing surface of the file mount 10, thereby fixing the paper fastener 1A to the file mount 10 (FIG. 2 (c)).
[0031]
After the paper fastener 1A is fixed to the file mount 10, the document 12 is filed by fitting the through hole 13 of the document 12 to the band metal fitting 3 in the same manner as in the known paper fastener 1A. After filing, the document 12 is fixed to the file mount 10 by bending the upper part of the band 3 protruding from the upper surface of the document 12 outward or inward along the upper surface of the document 12 (FIG. 2 (d) ₁ ). (D) ₂ ). FIG. 3 is a cross-sectional view of the file in which the document 12 is filed in this way. In this file, the plate-like member 2 of the paper fastener 1A is not exposed on the back surface of the file mount 10 and is smooth. Therefore, the plate-like member 2 is not caught when the files are arranged on a document shelf or the like.
[0032]
In addition, the file formed in this way surprisingly firmly fixes the paper fastener 1A to the file mount 10 even though the central slit 22 is formed in the paper fastener reinforcing sheet 100A that fixes the paper fastener 1A. For example, when filing about 160 sheets (625 g) of PPC paper, as shown in FIG. 6, one end of the filed document 12 is gripped and moved up and down as indicated by arrows or left and right as indicated by a pendulum. Even if it is shaken, as shown in FIG. 7, as shown in FIG. 8A, even if it grips the cover-side end portion 10a of the file mount 10 and shakes it up and down as indicated by an arrow or left and right like a pendulum. Place the file on the table with its front cover facing down, grasp the back cover side edge 10b, and then select the file as shown by the arrow in FIG. Open, as shown in more FIG (c), it is repeated to close the file, by the weight of the documents 12 that filing, paper fastener 1A is never peeled off from the file mount 10.
[0033]
When the file created in this way becomes unnecessary, the document 12 is removed, and the used band fastener 3 of the paper fastener 1A is pulled up obliquely upward as shown in FIG. At this time, since the long end slit 23 and the short end slit 24 having different lengths are formed in a C shape at both ends of the central slit 22, the long end slit 23 and the short end slit are formed. The force is applied unevenly to 24, and the force is transmitted as shown by the arrows in FIG. For this reason, a surface sheet tears and spreads along the dashed-dotted line shown in the figure, and as shown in FIG. 5, the paper fastener 1A can be removed from the file mount 10 smoothly.
[0034]
Since the chips of the top sheet 20 do not adhere to the paper fastener 1A thus removed, the removed paper fastener 1A can be reused immediately. Further, when the removed paper fastener 1A is discarded, it is preferable because the collection of the paper fastener 1A, the file mount 10 and the paper fastener reinforcing sheet 100A can be made thorough. Furthermore, fine chips are not generated from the top sheet 20, and the top sheet 20 remains integrally with the file mount 10, so that it is possible to prevent chips from being scattered.
[0035]
In addition to the above, the present invention can take various forms. For example, the shape of the topsheet 20 is not limited to a trapezoid with rounded corners, but may be a rectangle with rounded corners such as the paper fastener reinforcing sheet 100B of FIG. 9, or a half-moon shape like the paper fastener reinforcing sheet 100C of FIG. It is good.
[0036]
Further, as in the paper fastener reinforcing sheet 100D of FIGS. 11 and 12, the distance L4 between the side 20a of the surface sheet 20 and the central slit 22 on the center side of the file mount is set to the through hole 11 on the file mount and the central broken line. You may make it larger than the distance with 10c. In this case, as shown in FIG. 12, one end of the top sheet 20 crosses the central folding line 10c of the file mount 10, and the top sheet 20 is pasted across the cover 10X and the back cover 10Y of the file mount. To do.
[0037]
Further, like the paper fastener reinforcing sheet 100E of FIG. 13, the C-shaped end slit may be omitted. In this case, it is preferable to make the distance between the through hole 21 and the central slit 22 close so that the used paper fastener can be removed smoothly.
[0038]
The paper fastener that can be fixed according to the present invention adheres to one side of the plate-like member 2 in addition to the paper fastener 1A (FIG. 15) composed of a single plate-like member 2 and a band fitting 3 provided at both ends thereof. A layer 4 and a release paper 5 are sequentially provided (FIG. 17), a fastener body 1 composed of a plate-like member 2 and a band bracket 3 and a fastener 6 (FIG. 18), on one side of the plate-like member 2 What provided the adhesive layer 4 and the release paper 5 in order, etc. can be used.
[0039]

Evaluation A paper fastener (Fig. 15) (Paper Fastener, Richt) consisting of a single plate-like member 2 and band metal fittings 3 provided at both ends thereof is prepared, and this paper fastener is attached to a paper file mount (individual folder, KOKUYO). The paper fastener reinforcing sheet obtained in Example 1 was used for fixing, and 160 sheets (636 g) of PPC paper were bound. Next, the following (a) adhesion resistance experiment, (b) pendulum / drop experiment, and (c) fractionation experiment were performed.
[0043]
(a) Adhesion resistance experiment All the filing papers are turned over, it is checked whether the paper is fixed on the file mount, and as shown in Fig. 7, the file is swung up and down 10 times (5 reciprocations), and then the paper The fixing condition of the fastener was examined.
[0044]
Further, as shown in FIG. 8, the fixing condition of the paper fastener after opening and closing the file six times (three reciprocations) was also examined.
[0045]
As a result, the paper fastener did not lift from the file mount, and all the sheets were bound and firmly fixed to the file mount.
[0046]
(b) Pendulum / drop experiment As shown in Fig. 7, the file is swung to the left and right 10 times (5 reciprocations) like a pendulum, and then dropped spontaneously once from a height of 80 cm (the height of the office desk in the office). Then, the fixing state of the paper fastener was examined.
[0047]
As a result, the paper fastener was firmly fixed to the file mount with all the sheets bound.
[0048]
(c) When the paper was removed from the sorting experiment file and the paper fastener was further removed, the presence or absence of the sheet waste adhering to the paper fastener or the sheet waste falling around was examined.
[0049]
As a result, in the paper fastener, small thin pieces of the sheet were slightly attached to the corners of the plate-like member, but there was no sheet waste dropped around.
[0050]
Example 2
A paper fastener reinforcing sheet was prepared in the same manner as in Example 1 except that the adhesive layer was formed of a general type double-sided adhesive tape (Nystack, Nichiban Co., Ltd.). (A) Adhesion resistance experiment, (b) Pendulum / drop experiment (C) A fractionation experiment was conducted.
[0051]
As a result, in the (a) adhesion resistance experiment, the paper fastener slightly floated, and Example 1 was superior, but there was no problem in practical use. In (b) pendulum / drop experiment and (c) fractionation experiment, good results were obtained as in Example 1.
[0052]
Example 3
A paper fastener reinforcing sheet was prepared in the same manner as in Example 1 except that the top sheet was made of vinyl cloth (RBA, Dynic), and (a) adhesion resistance experiment, (b) pendulum / drop experiment, (c) fractionation The experiment was conducted.
[0053]
As a result, in the (a) adhesion resistance experiment, the paper fastener slightly floated due to the elongation of the top sheet, and Example 1 was superior, but there was no problem in practical use. (b) In the pendulum / drop experiment, good results were obtained as in Example 1. Further, (c) in the separation experiment, a small thin sheet of the sheet and an adhesive layer were attached to the paper fastener. Therefore, it was found that cloth cloth is more preferable as the top sheet in order to increase the separation efficiency.
[0054]
【The invention's effect】
When the paper fastener reinforcing sheet of the present invention is used, when the paper fastener is fixed to the file mount, the plate-like member of the paper fastener is not exposed on the back surface of the file mount. Therefore, it is possible to solve the problem of catching the plate-like member when the files are arranged on a document shelf or the like and put in and out.
[0055]
Further, the paper fastener can be firmly fixed to the file mount.
[0056]
Further, after the paper fastener is used for filing, the paper fastener can be easily removed from the file mount in a state where there is no adhesion of sheet waste, so that the reuse of the paper fastener can be promoted.
