Description

  The present invention relates to a sheet binding tool that is attached to a surface to be attached such as a file and binds sheets such as a loose leaf having a large number of perforations, a sheet having a pair of perforations, or a plastic film.

  As a conventional sheet binding tool of this type, there is generally known one made of a metal material integrally having a base and a pair of tongue-shaped pieces respectively extending from opposing ends of the base.

  In such a sheet binding tool, an adhesive layer is provided on one side of the base, and the adhesive layer is covered with a release sheet. When this sheet binding tool is attached to the surface to be attached, it is released from the base in a state where the tongue is bent with respect to the base so that the angle between the base and the tongue is about 90 degrees. The sheet is peeled off and the adhesive layer is adhered to the attachment surface of the file etc., and the tongue-like piece is passed through a pair of slits formed in the file etc. so that the tongue-like piece is opposite to the attachment surface. It can be attached by protruding. And when binding sheets, the tongue-shaped piece is passed through the perforations formed in the sheets, and then the tongue-shaped piece is folded back so that the tongue-shaped piece is substantially flush with the base. Thus, the sheets are bound.

  Moreover, what was described in patent document 1 is known as another type of sheet binding tool. In this sheet binding tool, a front surface side synthetic resin sheet disposed on the front surface side of the base and a back surface side synthetic resin sheet disposed on the back surface side of the base are disposed. The periphery of the synthetic resin sheet on the side is welded. A slit for projecting a pair of tongue-like pieces is formed in the front side synthetic resin sheet, and an adhesive layer with a release sheet is attached to the rear side synthetic resin sheet. When this sheet binding tool is attached to the attached surface, it can be attached by peeling the release sheet from the synthetic resin sheet on the back side and bonding the adhesive layer to the attached surface such as a file. In this case, the base and the tongue-like piece are made of a metal material or a synthetic resin material.

  However, in the conventional sheet binding tool, when the base and the tongue-like piece are made of a metal material, the file constituting the attachment surface is usually made of a paper material or a synthetic resin material. There is a problem that it takes time and effort.

  On the other hand, when the base and the tongue-shaped piece are made of a synthetic resin material, there are few problems regarding disposal, but there is a problem that the shape retention is lacking. If the shape retention is lacking, the tongue piece will be bent to some extent with respect to the base in the bound state, so the binding ability of the sheets is bad, and files etc. are handled violently, There is a problem that the bound sheet of heels falls out of the tongue-shaped piece.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a sheet binding tool which requires less trouble at the time of disposal and has a high sheet binding capability.

In order to achieve the above object, a device according to claim 1 is provided with a binding tool main body including a base and a pair of tongue-shaped pieces extending from opposite ends of the base, and the pair of tongue-shaped pieces is formed into sheets. In the sheet binding tool adapted to bind sheets by passing through the formed perforations,
The binding tool body is made of a non-metallic material having shape retention.

  The invention according to claim 2 is a state in which the tongue-like piece of the binding tool body according to claim 1 is bent from about 90 degrees with respect to the base until the bending angle is about 0 degrees. The angle returning to the bending direction is 20 degrees or less.

  The invention described in claim 3 is the one described in claim 1 or 2, wherein the binding tool body is made of a polyolefin resin material.

  The invention described in claim 4 is characterized in that, in the invention described in claim 1 or 2, the binding tool body is made of a paper material sheet made of a paper material coated with a synthetic resin film on the front surface side and the back surface side. And

  The invention according to claim 5 is characterized in that, in the apparatus according to any one of claims 1 to 4, an adhesive layer is provided on one surface side of the base.

The invention according to claim 6 is the device according to any one of claims 1 to 4, wherein a surface side synthetic resin sheet is disposed on a surface side of the base, and a back surface side is disposed on the back surface side of the base. A synthetic resin sheet is disposed, and the peripheral edge of the front surface side synthetic resin sheet and the back surface side synthetic resin sheet is welded,
The surface-side synthetic resin sheet has a pair of openings through which the pair of tongue-shaped pieces pass,
The back side synthetic resin sheet is provided with an adhesive layer.

  Further, the present invention is characterized by a file to which the sheet binding tool according to any one of claims 1 to 6 is attached.

  According to the present invention, the problem relating to disposal can be reduced by configuring the binding tool body from a non-metallic material having shape retention. In addition, by having shape-retaining properties, the tongue-shaped piece is bent with respect to the base, and after passing the tongue-shaped piece through the perforations formed in the sheets, the bending angle of the tongue-shaped piece is about 0 degree. When the sheet is returned to 180 degrees or 180 degrees, folding back due to the spring back of the tongue-like piece is reduced, so that the sheets can be securely held in a bound state, and the sheet binding with high binding ability can be held. Can be used as a tool.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a sheet binding tool according to a first embodiment of the present invention.

  The sheet binding tool 10 includes a binding tool body 16 including a base 12 and a pair of tongue-like pieces 14 and 14 extending outward from opposing ends of the base 12. The binding tool body 16 has a shape retaining property. It is comprised from the polyolefin-type resin material which has.

  An adhesive layer 18 is provided on one surface of the base 12. The adhesive layer 18 can be constituted by a double-sided adhesive tape whose one surface is covered with a release sheet 19.

  The binding tool main body 16 has a tongue-like piece 14 that can be bent with respect to the base 12, and after the tongue-like piece 14 is bent with respect to the base 12 by about 90 degrees, the bending angle is set to about 0 degrees. It shall have shape retention so that when it is returned, the bending return angle returned by springback is 20 degrees or less. The binding tool body 16 having this shape retaining property can be made of, for example, a polyolefin-based resin material. Examples of the polyolefin resin include high density polyethylene resin, medium density polyethylene resin, low density polyethylene resin, linear low density polyethylene resin, and polypropylene resin.

  Moreover, as thickness of the binding tool main body 16, although it can be set as arbitrary thickness, it is good to set it as 0.2-1.5 mm, Preferably, it is 0.6-1.0 mm or 0.8 mm.

  In order to attach the sheet binding tool 10 configured as described above to the attachment surface A, first, the tongue-like piece 14 is bent about 90 degrees with respect to the base 12 as shown in FIG. After the sheet 19 is peeled off, a pair of tongues 14 are inserted into a pair of slits S, S formed on the attachment surface A such as the back cover of the file F, and the base 12 and the adhesive layer 18 are attached to the attachment surface A. Thus, the sheet binding tool 10 can be attached to the attachment surface A.

  Next, when binding the sheets, after passing the tongue-like pieces 14 and 14 bent about 90 degrees with respect to the base 12 through a pair of perforations of the sheets P as shown in FIG. As shown in FIG. 3 (b), the bent pieces of the tongue-like pieces 14, 14 are returned so that the bent angle is close to 0 degrees. As a result, the sheets P cannot pass through the tongue-like pieces 14, 14, and are bound into the sheet binding tool 10.

  Here, if the tongue-like pieces 14 and 14 are largely bent back due to the spring back, the sheets may fall out of the tongue-like pieces 14 and 14 depending on how to handle them. Since the folding return angle θ representing such folding return is suppressed to 20 degrees or less due to the shape retaining property of the main body 16, the sheets can be reliably held in a bound state, and the binding ability is high. It can be set as a sheet binding tool.

  In such a sheet binding tool 10, since the binding tool body 16 is made of a synthetic resin material, it can be usually discarded together with a file having a mounting surface made of a paper material or a synthetic resin material. , It does not take time to sort.

  The attached surface can be arbitrary, but can be the surface of the file F that binds sheets. Further, the sheet binding tool 10 can be attached to the attachment surface A by any means such as welding, in addition to being bonded via the adhesive layer.

  FIG. 4 illustrates a sheet binding tool attached to the folded portion or the mounting piece, where the attachment surface A to which the sheet binding device 10 is attached is a folded portion provided inside the file F or an attachment piece welded to the inside of the file. The example which attached 10 is shown. Thus, the sheet binding tool 10 can be attached to an arbitrary surface provided in a file or the like for binding sheets.

  5-6 is a figure showing 2nd Embodiment.

  In the second embodiment, the portion of the base 12 of the binding tool body 16 is surrounded by a synthetic resin film sheet. That is, the front surface side synthetic resin sheet 20 is disposed on the front surface side of the base 12 of the binding tool body 16, and the back surface side synthetic resin sheet 22 having substantially the same shape and dimensions as the front surface side synthetic resin sheet 20 is disposed on the back surface side. And the peripheral edges 20a and 22a of the front surface side synthetic resin sheet 20 and the back surface side synthetic resin sheet 22 are welded by a high frequency welder.

  The front side synthetic resin sheet 20 and the back side synthetic resin sheet 22 can be made of a synthetic resin material such as vinyl chloride resin.

  A pair of openings 20b and 20b are formed in the surface side synthetic resin sheet 20, and the pair of tongue-like pieces 14 and 14 pass through the pair of openings 20b and 20b.

  An adhesive layer 24 with a release sheet 23 is provided on the back side of the back side synthetic resin sheet 22.

  In order to attach the sheet binding tool 10 configured as described above to the attachment surface A, after peeling off the release sheet 23, the back surface side synthetic resin sheet 22 is attached to the attachment surface A via the adhesive layer 24. By bonding, the sheet binding tool 10 can be easily attached to the attachment surface A. Since the area of the back surface side synthetic resin sheet 22 is larger than the area of the base 12, a large area of the adhesive layer 24 can be secured, and a strong adhesive force can be obtained with respect to the attachment surface A.

  Further, when sheets are bound, the same procedure as in the first embodiment can be performed, and at this time, the sheets are securely held in a state of being bound by the shape retaining property of the binding tool body 16. And a sheet binding tool having high binding ability.

  FIG. 7 shows a modification of the second embodiment. In this example, the binding tool body 16 includes a base 12 and a pair of tongue-like pieces 14 extending inward to the base 12 side by notches 12a from opposite ends thereof. However, the material of the binding tool body 16 is the same as that of the previous embodiment.

  Also in this case, the same effects as those of the second embodiment can be obtained, and the folding return angle of the tongue-like piece 14 is small, so that the sheets can be reliably held in a bound state.

  In 1st Embodiment and 2nd Embodiment (and its modification), instead of comprising the binding tool main body 16 from the polyolefin-type resin material which has shape retention property, as shown in FIG. It can comprise the paper material sheet | seat 30 which consists of a paper material coated by bonding the synthetic resin film 32 to the side. The synthetic resin film 32 can be a polyolefin film such as a polyethylene film. The thickness of the binding tool body 16 may be any thickness, but may be 0.2 to 1.5 mm, preferably 0.6 to 1.0 mm or 0.8 mm.

  If only paper material is used, there are difficulties in durability and shape retention, but the binding tool body 16 is composed of a paper material sheet coated with a synthetic resin film on the front and back sides of the paper material sheet made of paper material. By doing so, shape retainability can be given.

  Further, by constituting the binding tool main body 16 from the paper material sheet, it is possible to eliminate the need for sorting at the time of disposal.
