The left and right side edges 70R, 70L of the plastic sheets S ₁ , S ₂ are heat-sealed to form a bag shape, and the left side edge 70L is provided with binding holes 72, 72 for binder. There are things set up.

[Problems to be solved by the device]

However, while these have the advantage that documents and materials filed by sandwiching them between _two plastic sheets S ₁ and S ₂ can be freely taken in and out, the documents and materials are misaligned and tilted or overlapped with each other. There was a flaw.

Therefore, the product catalogs, pumplets, price lists, specifications, etc. carried by the salesperson cannot be shown to the customer while sandwiching them between the plastic sheets S ₁ and S ₂ .
Since it has to be taken out from between the plastic sheets S ₁ and S ₂ each time, there is a problem in that damage is likely to occur.

In order to prevent the documents and materials from being damaged, there is also a method of sandwiching them between two transparent polyester sheets and heat-sealing them, but in this case, expensive heat with a heating roll is used. A sealing device is required.

Therefore, according to the present invention, it is possible to file a document or material sandwiched between two plastic sheets so as not to move without using a heat seal device, and further, the file can be extremely easily performed. At the same time, the technical issue is to be able to classify the documents and materials filed.

[Means for Solving the Problems]

In order to solve this problem, the present invention is a file sheet in which documents and materials are sandwiched between two plastic sheets, and the two plastic sheets are formed into a spread and one plastic sheet is used. Is formed with an index part for displaying an index or a heading along the edge side, and an adhesive layer for releasably adhering the other plastic sheet except for the part where the index part is formed. The other plastic sheet is formed of a transparent sheet having its fore edge side superposed on the index portion.

[Action]

According to the present invention, two plastic sheets are formed into a double-page spread, and the other plastic sheet is removably superposed on the adhesive layer formed on the one plastic sheet.

When inserting a document or material between the two plastic sheets, first, the index portion formed along the edge side of one plastic sheet and the edge side of the other plastic sheet that overlaps the index portion are overlapped. Hold each of them with your left and right hands and peel off the two plastic sheets from each other.

Then, after pasting a document or a material on the adhesive layer formed on one of the plastic sheets, the other plastic sheet is covered on the adhesive layer, and the paper and the material are put on again.

As a result, documents and materials sandwiched between the two plastic sheets are filed in a state in which they do not move at all.

In addition, since at least one of the two plastic sheets is formed of a transparent sheet, if it is a single-sided printing document or material, the entire contents can be viewed as a file.

Further, since one plastic sheet has an index portion for displaying an index or a headline along the edge side thereof, filed documents and materials can be sorted or organized.

Further, since the edge side of the other plastic sheet is superposed on the index portion, the two plastic sheets that have been overlaid on each other can be easily peeled off and at the same time superposed on the index portion. Since the plastic sheet is made of a transparent sheet,
The index and heading displayed in the index section will not be invisible or difficult to see.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a perspective view showing an example of a filing sheet according to the present invention, and FIG. 2 is a sectional view showing an essential part thereof.

In this example, an A4 size or B5 size file sheet F ₁ is shown, and a colorless transparent or colored transparent polypropylene sheet (OPP) cut into A3 size or B4 size is an anchor agent formed on one side thereof. The two primer sheets ₁ are folded in two so as to face each other to form two spread plastic sheets S ₁ and S ₂ .

Then, on one of the plastic sheets S ₁ , from the top of the primer layer 1, about 50% polyacrylic acid ester (solid content concentration ≈ 66%) and about 30% methyl methacrylate / butyl acrylate (solid content concentration ≈ The adhesive layer 2 is formed by applying and drying an emulsion-type adhesive containing 33%) as the main component, and releasably adhering the other plastic sheet S ₂ to it.

Further, the plastic sheet S ₁ is provided with an index portion 3 formed by sticking a paper tape T on the surface of the adhesive layer 2 along the edge side thereof, and on the index portion 3,
The small sides of the plastic sheets S ₂ are adapted to be overlapped.

The polypropylene sheet (OPP) is selected to have a thickness of about 70 μm so that the _two plastic sheets S ₁ and S ₂ are superposed on each other without wrinkling.

In addition, the primer layer 1 is 0.25 to 0 of polyethyleneimine, which is optimal as an anchor agent for polypropylene sheets.
It is formed by applying a 5% solution and drying it under heating at 60 to 80 ° C.

Then, documents and materials W are placed between the plastic sheets S ₁ and S _2.
When a file is sandwiched between, the index portion 3 formed along the fore edge side of the plastic sheet S ₁ and the plastic sheet overlapping the index portion 3
Holding the small side of S ₂ in each of the left and right hands, pull the plastic sheet S ₂ in the direction of peeling it from the adhesive layer 2 of the plastic sheet S ₁ as shown in FIG. 2, and as shown in FIG. Peel S ₁ and S ₂ apart.

At this time, the index portion 3 of the plastic sheet S ₁
Since the front edges of the plastic sheets S ₂ laid on top of each other are not superposed on each other, they can be easily grasped by the left and right hands as they are, and the index portion 3
Is formed over the entire length of the plastic sheet S ₁ along the edge thereof, so that the index portion 3 and the edge of the plastic sheet S ₂ superposed on the index portion 3 can be grasped with certainty.

Therefore, the two plastic sheets S ₁ and S ₂ superposed by the adhesive layer 2 can be peeled off very easily.

Then, when both the sheets S ₁ and S ₂ are peeled off, as shown in FIG. ₁ , after a document or material W is pasted on the adhesive layer 2 of the plastic sheet S ₁ , the plastic sheet is put on the adhesive sheet 2.
Put on S ₂ and put it on.

Thus two transparent plastic sheets S ₁ , S ₂
The documents and materials W sandwiched between them are filed so that they do not move at all, and both the front and back sides can be viewed as they are filed.

Further, since the index portion 3 for displaying an index or a heading is formed on the edge side of the plastic sheet S ₁ ,
It is convenient for sorting and organizing filed documents and materials W.

Further, since the plastic sheet S _{2 which} is superposed on the edge portion on the index portion 3 is a transparent sheet, the index or heading displayed on the index portion 3 can be seen through the plastic sheet S _2. it can.

Although many documents and materials W to be filed are printed by a computer or a word processor printer, the adhesive layer 2 is formed of an emulsion adhesive that does not use a solvent or a plasticizer as in the embodiment. In this case, the ink characters of the printer printed on the document or the document W are not likely to bleed, and this type of document or the document W can be permanently stored.

Next, the file sheet F ₂ shown in FIG. 3 has an ear piece-shaped index portion 3 along the edge of the plastic sheet S _1.
Is formed, and the adhesive layer 2 is formed on the surface of the plastic sheet S ₁ excluding the index portion 3, and the ear piece 30 that overlaps the index portion 3 is formed on the edge side of the plastic sheet S _2. ing.

The index part 3 is adapted to display an index or a heading by directly writing characters or symbols on the surface of the plastic sheet S ₁ with a felt-tip pen of oil-based ink or by attaching a paper sticker or the like. There is.

Next, the file sheet F ₃ shown in FIG. 4 and FIG.
Two transparent plastic sheets S ₁ and S ₂ cut into A4 size or B5 size are bound with a double-sided adhesive tape 40 to form a two-page spread.

Then, binding holes 41, 41 for binding to the binder are formed in the binding portion.

In addition, the plastic sheet S ₁ has the adhesive layer 2 formed on the surface of the polypropylene sheet (OPP) on which the primer layer 1 of the anchor agent is formed, and the paper tape T is attached from above the adhesive layer 2 along the edge side thereof. The index portion 3 is formed.

In addition, an inexpensive unprocessed polypropylene sheet (OPP) having no primer layer 1 is used for the plastic sheet S ₂ on which the adhesive layer 2 is not formed to reduce the material cost.

In this way, each file sheet F ₃ can be stored not only by itself but also by binding it in one binder.

Also in this case, since each file sheet F ₃ is formed with the index portion 3 for displaying an index or a heading on the edge side, the desired file sheet F _{3 in} which the necessary documents or materials W are filed is displayed. You can easily find out.

Further, the binder binding holes 41, 41 formed in the file sheet F ₃ are reinforced by the double-sided adhesive tape 40 used to bind the _two plastic sheets S ₁ , S ₂ together. There is no possibility that the binding holes 41, 41 will be torn and broken.

In the embodiment, the case where both the plastic sheets S ₁ and S ₂ are transparent sheets has been described, but the present invention is a plastic sheet in which the index portion 3 is formed.
The case where S ₁ is formed of a semitransparent or opaque sheet is also included.

[Effect of device]

As described above, the file sheet according to the present invention is
You can file documents and materials sandwiched between two plastic sheets so that they do not move at all without using an expensive heat seal device, and you can see the entire contents in the filed state .

In addition, one plastic sheet has an index part for displaying an index and a heading along its edge, so that filed documents and materials can be sorted and organized, and moreover, Since the edge side of the other plastic sheet is overlapped on the index part, the two plastic sheets that have been overlaid can be easily peeled off, and at the same time, the plastic overlapped on the index part Since the sheet is formed of a transparent sheet, it has various excellent effects that the index and heading displayed in the index portion are not invisible or difficult to see.
