Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document binding fastener in which a document is bound by a mounted fastener and is folded and folded and stored.

[0002]

2. Description of the Related Art Two sheets of paper or plastic sheet
As a fold, it is well known that a document binding file is used for binding, storing, and storing documents with a fastener attached to the file.In this file, the binding document marking is directly written on the back of the file. Alternatively, a piece of paper indicating the contents of the bound document is attached, or a window for inserting the piece of paper is provided, and the binding of the document is performed from a slit provided on the back or side of the file with a fastener. Most of the leg pieces are inserted into the inside of the file to be spelled in, and in this type, the fastener main body exists outside the file. On the other hand, it has been proposed, for example, in Japanese Utility Model Publication No. 7-50227 that the main body of the fastener does not exist outside the file but the entire fastener should appear inside the file.

[0003]

Among the conventional files, the former one is as follows:
When the contents are written directly in the file, it takes time to erase the written characters when reusing the file when the contents are no longer needed. There is also a problem that it takes time and effort to replace pieces of paper, and the heading and heading paper become dirty with the lapse of the usage period, and a file provided with a window that allows easy insertion and removal of paper pieces increases file cost. Yes, the same applies to stains on the heading paper.

As for the fasteners attached to the file, the fastener binding pieces are inside the file, but the other fasteners are outside the file. It has been pointed out that the fasteners may become entangled and cause inconvenience to the work.In addition, the fastener that was proposed earlier was attached to the inside of the file. The adhesive sheet is fixed, and further, the fixing sheet having the binding band is adhesively fixed on the base sheet, and the labor and parts are required.
The adhesive strength of the adhesive provided on the fixing sheet decreases, the document cannot be supported, and there is a concern that the sheet will fall off from the file. In view of these points, the heading sheet of the present invention is easy to insert into and remove from the back of a file and does not stain even after long-term use, and the fastener is entirely held inside the file. By using the zipper exposed on the outside of the file, you can select a safe and beautiful file that eliminates the inconvenience of use and accidents such as hand injury, and even the colors of the front and back covers can be freely selected. It is an object of the present invention to provide a file that has a beautiful appearance and is capable of managing and storing it according to the color of the document, and a method of producing the file.

[0005]

In order to solve the above-mentioned problems, the present invention provides a back cover 2 of a transparent or translucent plastic sheet and a back cover 2 which can be heat-sealed with the back cover 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a document binding file according to the present invention, which is a plan view in a developed state, FIG. 2 is a vertical sectional side view taken along the line AA in FIG. 1, and FIG. FIG. 4 is a plan view of the back cover.

Reference numeral 1 is a front cover and 2 is a back cover. This back cover 2 is a transparent or translucent plastic sheet, which may be a colored sheet. It is also cut off. At the time of this cutting, it is preferable to cut the back cover 2 so that the upper end 3 of the back cover 2 has a notch 4 and the lower end 5 has a tongue piece 6.
By setting the tongue piece 6 to have the same shape and size, it is possible to continuously cut the raw material without waste. Although the tongue 6 and the notch 4 have the same shape, if the size of the notch 4 is slightly larger than that of the tongue 6, the cutting efficiency for punching is increased. Like the back cover 2, the front cover 1 is also cut from the material according to the desired length, but unlike the back cover 2, it does not matter whether it is transparent or opaque. The front cover 1 should be a plastic sheet or a plastic film on paper, since it may be heat-bonded to the plastic sheet which is the back cover 2. A sheet that can be heat-sealed by laminating is used, or a sheet that can be heat-sealed by applying plastic to paper is used. A fold line 7 is provided over the entire length on the side of the front cover 1 and the back cover 2 cut in this way. Until now process A
Becomes

A slit 8 is provided at a position outside the fold line 7 of the cut front cover sheet 1. The binding piece 10 of the fastener 9 is inserted into the slit 8 and the fastener 9 is attached to the front cover 1. This mounting will be described with reference to FIG. 3. A fastener 9 is placed on the back side of the front cover 1 provided with the slit 8 in FIG. 3, the binding piece 10 of the fastener 9 is inserted through the slit 8 and protrudes upward, and the binding piece 10 is attached. The mounting is completed by lying down on the surface of the front cover 1, and the process up to this point is the process B.

The front cover 1 with the fastener 9 attached in this manner is bent from the fold line 7, and the bending at this time is performed with the binding piece 10 of the fastener 9 inside. Similarly, the back cover 2 is also bent inward from the fold line 7 on the side where the fold line 7 is provided. This is the process C, but the side bending of the back cover 2 is the next process after the back cover 2 is cut from the original fabric and the fold lines 7 are provided. It may be performed at any time up to the step of overlapping and heat-sealing the front cover sheet 1.

The front cover 1 and the back cover 2 thus formed are laterally superposed on each other and heat-sealed. First, the back cover 2 is turned down, and the front cover 1 is turned up. This is because the side of the back cover 2 shown in FIG. 4 where the notch 4 and the tongue 6 are formed is placed below the side of the front cover 1 shown in FIG. 3 where the slit is provided. It is understood by superimposing the fold lines 7. In the front cover 1 and the back cover 2 which are overlapped in this way, the terminal 11 of the back cover 2 and the front cover 1 are linearly heat-sealed 12 over the entire length in the process D.

In this way, the front cover 1 and the back cover 2 are one of the planned two heat-sealed portions, and the heat-melted portion on the left side indicated by reference numeral 12 in FIGS. Although both covers have been united in one part by the attachment, the other part to be heat-sealed, that is, cover 1
Since the position of the terminal 13 of the front cover 2 on the back cover 2 is open, the heading sheet 14 is inserted between the back cover 2 and the front cover 1, and then the terminal 13 of the front cover 1 and the back cover 2 are inserted. And 15 are heat-sealed linearly over the entire length. This heat fusion 12,
A superposing section 16 is formed by the side of the front cover 1 and the back cover 2 superposed by 15, and the superposing section 16 is formed.
2, the heading paper 14 is stored, the fastener 9 is attached, and the binding piece 10 of the fastener 9 is in a state of protruding inward of the file. This step is E, but the file shown in FIG. 1 is folded in two in order to be in the state of the file actually used following this step. This two-fold is bent at the fold line 7. However, this folding may be done anytime thereafter.

The thus obtained file has a transparent or semi-transparent plastic back cover 2 and the back cover 2 and the heat-fusible front cover 1 overlapped by a desired length. , The back cover 2 is placed on the outside and the front cover 1 is placed on the inside, and the terminals 11 and 13 on the side where the back cover 2 and the front cover 1 are overlapped are respectively attached to the front cover 1 and the back cover 2. A heading sheet 14 is freely inserted into and taken out of the overlapping portion 16 formed by thermal fusion bonding 12 and 15 and is located at a position close to the terminal 13 of the thermal fusion bonding 12 of the overlapping portion 16. The binding piece 10 of the fastener 9 is projected from the inside of the overlapping portion 16 through the slit 8 provided in the front cover 1 of the above, and the fastener 9 is attached, and the protruding binding is performed at a position substantially at the center of the overlapping portion 16. Fold it in half with piece 10 inside. It was a document binding for the file.

[0022]

The document binding file according to the present invention is
Since it is configured as described above in detail, the transparent or semi-transparent back cover is the outer side of the file and the front cover is the inner side to form the overlapping portion, and the heading paper is placed in the space of the overlapping portion. It is designed so that it can be inserted and taken out, so that the heading paper does not get dirty even after many years of use, the heading paper marking is clearly visible, and the contents document is exchanged. When this is done, the heading sheets stored in the stacking section can be easily replaced, so there is no need to attach a new heading sheet, unlike the conventional heading surface. There is no need to attach a special window to the back of the file. When cutting the back cover, a notch is set on the side of the upper end that will be the back cover, and a tongue of the same shape and size as the notch is set on the side of the lower end to cut the cut. It is possible to continuously cut with little loss that occurs due to the formation of and, and this notch is convenient for inserting and removing the heading paper in the obtained file, and it also has a tongue. The piece prevents the inserted heading sheet from falling off during use by the tongue piece. Furthermore, since the fastener is installed and installed inside the overlapping part, and only the binding piece is exposed inside the file, there is no extra protrusion on the outside of the file. When using, like the conventional files, the fastener exposed on the outside of the file does not hurt your hand or get entangled with other files, and you can safely and beautifully maintain the binding function. In addition to this, since the colors of the front cover and back cover can be freely combined, not only a file with a beautiful appearance can be obtained, but depending on the color selection, management by content of the bound document can be performed. It can also be managed by the color of the file. Such a document binding file can be produced and provided in the most economical and simple process.
