Description

According to the present invention, it is easy to put in and take out sheets such as a plurality of documents and slips, and even if the number of sheets is large, it can be accommodated without difficulty, and writing with a pencil or the like and printing with a printer are possible. Sheets that can contribute to the reduction of waste Paper files.

Files for synthetic resin sheets, which are widely used to store multiple sheets of documents together, are made by folding one flexible synthetic resin base material into valleys and folding the front and back sheets. The sheets are overlapped, and the lower edge portions thereof are heat-sealed and bonded to form a storage portion inside, and most of them have a size for accommodating A4 size sheets.

Most of the conventional files for sheets are made of a transparent or translucent synthetic resin material so that the stored sheets can be visually recognized from the front side and can be easily molded.

I couldn't find it.

(1) Since the conventional synthetic resin file described above has a structure in which the lower edge is heat-welded by folding it in half, the welded portion of the lower edge begins to peel off when the number of stored sheets is large, and this peeling is used. There is a drawback that it gradually expands with the process and eventually becomes unusable as a file.
(2) Since the file is molded from a synthetic resin material, a felt-tip pen is used because it is not possible to write necessary information with a pencil, ballpoint pen, or fountain pen, but there is a drawback that it cannot be modified or erased. For this reason, it is troublesome to put up a paper sticker and write. There is also the problem that shredders cannot shred.
(3) Furthermore, when it is disposed of, it is disposed of as plastic waste, but there is a problem that it is contrary to the conservation of the global environment of reducing plastic waste.

The present invention has been made in view of the above-mentioned drawbacks of the prior art and unsolved problems, and it is easy to put in and take out sheets such as a plurality of documents and slips, and it is not unreasonable even when the number of sheets is large. It can be accommodated and is lightweight, so it is highly portable. It is easy to use because it can be recorded with pencils, fountain pens, ballpoint pens, printers, etc. and multicolor printing, and it can be shredded with a shredder. The purpose is to provide sheets made of paper that are friendly to the global environment because they can be used for remanufacturing resources and contribute to the reduction of plastic waste.

(1) The means of the present invention according to claim 1, which is configured to solve the above-mentioned problems, abuts both inner surfaces of the front cover and the back cover and attaches one end side in the width direction by a vertical attachment portion. By sticking the lower end side in the vertical width direction with the horizontal sticking part, the edge side is closed in a substantially L shape to form a storage part inside, and the front cover and the back cover are made of paper. It is a file-made file, and the front cover or the back cover is provided with a storage amount increasing portion along the vertical attachment portion, so that the storage portion can be expanded.
(2) The storage amount increasing portion forms cuts in the front cover or the back cover at regular intervals to form a plurality of spacing expanding pieces in a row, and each spacing expanding piece is a folded portion and its tip side. It is composed of the adhesive portion of the above, and the adhesive portion is attached to the back cover or the front cover.
(3) Further, the front cover or the back cover is provided with a lower storage amount increasing portion along the horizontal attachment portion, and the lower storage amount increasing portion makes cuts in the front cover or the back cover at regular intervals. A plurality of interval expansion pieces are formed in a row, and each interval expansion piece is composed of a folded portion and an adhesive portion on the tip side thereof, and the adhesive portion is attached to the back cover or the front cover. It is good to do it.
(4) Further, the interval expanding piece sets the capacity of the storage portion by selecting the length of the folded portion.
(5) Further, the back cover may have a wider or vertical width larger than that of the front cover, and the overhanging portion overhanging the front cover may be an index portion.
(6) The front cover or the back cover may be formed of paper having a thickness different from that of the back cover or the front cover.

Since the present invention is configured as described above, the following effects are obtained.
(1) Since a storage capacity increasing part is provided between the front cover and the back cover so that an enlarged space piece is interposed, it is easy to put in and take out sheets such as multiple documents and slips, and the number of sheets is large. Even in this case, since no excessive force is applied to the vertical attachment part, it does not come off and has excellent durability.
(2) Sheets Paper files are made of paper, so they are lightweight and highly portable. You can write with a pencil, fountain pen, or ballpoint pen, and you can often print the title of a proposal with a printer. Color printing is also possible, so it is easy to use, and it can be shredded with a shredder.
(3) Since the front cover and the back cover made of paper are pasted together to form a file, it is possible to produce a combination of papers having different thicknesses.
(4) Since it can be made by remanufacturing, resources can be utilized, and it can be shredded into remanufactured resources. Moreover, it is also useful for the global environment because it contributes to the reduction of plastic waste.
