JP2010269529A - Easy document folder - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide an easy document folder made of only one sheet folded into half, which eliminates disadvantages of a conventional easy file folder such as a clear file folder with its two sides sealed in an L-shape, in which documents are easy to slip out of the two other open sides because a document filing function is not provided and also the documents cannot be seen while being filed. <P>SOLUTION: A flexible thin sheet cut into an approximately square is folded at the center thereof to make a front cover and a back cover. The top end and bottom end of the portion folded along the center folding line of the twofold sheet are stuck to each other with the length of an intended document binding margin. A tongue-like cut piece is provided close to the opposite side to the center folding line on the back cover so that the tip thereof faces the center folding line. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  As with a conventional clear file, etc., a simple file that folds a sheet in two and seals the bottom is closed, the other two are opened, and a paper sheet such as a document is put in and out between them. .

  Conventionally, in order to temporarily organize and store a relatively small number of roses, from several to a dozen or so, a square plastic sheet, such as a clear file, is folded in half at the center to form a central fold. On the other hand, a simple file in which two sides are closed by sealing the lower end in an L shape has been widely used. Although the document is a simple file method that is sandwiched between front and back sheets and supported by two L-shaped closed sides, it is still widely used because it is inexpensive and simple. However, in order to view the documents, all the documents must be taken out from the file one by one, and there are problems such as the documents popping out from two sides that are not closed depending on how they are handled.

On the other hand, a document with a binding hole has been proposed in which a part of the back cover is cut and raised into a nail shape and inserted into the binding hole (Patent Document 1). It is limited, and it is necessary to prevent falling from the bottom side, and the above problems have not been solved. Also, in the conventional clear file with two L-shapes closed, a tongue-shaped cut piece is provided on the open side in the opposite direction to the center fold, and the tip is directed to the center fold to prevent the document from popping out. A proposal has also been proposed (Patent Document 2). However, this proposal is not protected against the jumping out of the remaining one, and the popping out prevention is incomplete, and it is impossible to turn the document and view it while the document is filed. In addition, a method has also been proposed in which a document is sandwiched between plastic sheets such as a clear file, and the binding margin of the document is sandwiched by a long clip-like material from the outside of the sheet folding part (Patent Document 3). However, the clip portion is bulky and far from an inexpensive and easy file like the present invention.

  The problem to be solved by the present invention is a conventional file used for short-term storage of a relatively small number of documents, and in a simple file such as a square sheet like a clear file folded in the middle. However, it is also possible to provide a simple file at a low cost that allows the document to be viewed in the filed state without taking out the document from the file, and also provides a function for preventing the document from jumping out of the file.

  The problem-solving means is composed of a substantially rectangular flexible sheet that is folded in two at a central fold to form two front and back covers, and the folding of the front and back covers is performed. A tongue-shaped document holding member is provided so that the upper and lower ends on the front side are fixed while maintaining the length of the binding margin of the document, and the tip is near the end facing the folding part of the cover. It is a file characterized by being.

The effects of the invention are as follows. That is, a conventional square plastic sheet is folded in half, the bottom is sealed and the L is just closed, the two are closed, and the other two are open, the bottom is sealed and closed on all sides. Therefore, in order to see the file that was filed, it was necessary to take out the document from the file one by one, and the file was open in two directions even when it was being filed. However, in the file according to the present invention, if the document is inserted between the front and back covers until the end of the document hits the central fold, and the document is pulled into the tongue-like notch 5 near the opposite side of the central fold of the file back cover, Is a pocket surrounded by the sheet folding portions 9 and 10 and the center folding line 4 provided at the center folding line side end parts of the upper and lower sides of the folded sheet. By inserting the opposite long side into the notch 5, the document is completely fixed to the back cover. As a result, the document is prevented from popping out, and if you turn the front cover, you can easily remove the document one by one from the tongue-shaped notch, and you can see it as if turning a normal document. However, the shortcomings have been improved while being easy to handle. The above effect has the great advantage that the simplest modification of the same production line can be performed without increasing the amount of use area of the conventional simplest L-shaped two-way closed file and the flexible sheet to be used. This is because the present invention is based on a novel idea of closing the upper and lower sides of the file by the binding margin width of the document, which breaks the concept of the conventional clear file. Originally, in the conventional clear file, it is a role to organize and store rose paper sheets that are not even stapled for a short period of time, and there is no binding hole in the document, even if it does not try to use even the binding hole Because it was a file of, it was not bound with a binding hole or stapled. However, there is always a margin for the binding margin on the paper sheet, and as a result of considering its effective use, a clear file having an unprecedented function has been invented. The flexible thin sheet used in the present invention is not limited to a plastic sheet, but can be a paper, and is not transparent. However, the printed pattern can be enjoyed as a cover of a document more than a plastic sheet, and the above-described effects are the same. . Further, as shown in Patent Document 3, there is a method in which the folding portion of the clear file is clipped from the outside with a clip at the binding margin portion of the document, but the cost is high and the binding portion is bulky. But cheap and smart.

  1 to 3, an embodiment of the present invention will be described as a file for an A4 size document. FIG. 1 is a polypropylene sheet according to the present invention before folding in half, and the thickness is 0.2 mm. There is a crease 4 at the center and a tongue-shaped cut piece 5 as a document pressing member on the back cover 3. The front cover 2 is provided with a crease 6 for facilitating opening of the front cover, but may be appropriately used depending on the thickness, rigidity, etc. of the sheet to be used.

  In FIG. 2, the sheet is folded in half, and the ends of the upper and lower sides on the side of the central crease are ultrasonically sealed to provide sheet fixing portions 7 and 8. A pocket 9 surrounded by the central folding line 4 and the sheet fixing portions 7 and 8 is completed. It is the figure which opened the front cover halfway in that state. Note that the fixing width of the sheet fixing portions 7 and 8 is a width of a binding margin that can be used to form a binding hole in a normal document, and is usually provided with a margin. In this embodiment, the fixing width was 2 cm.

FIG. 3 shows a state in which the long side end corresponding to the binding margin of the document P is inserted into the pocket made in FIG. 2 and the opposite long side end is inserted into the tongue-shaped cut piece 5. The front cover shows half-open. As a result, the movement of the document P is completely fixed by the pocket 9 and the tongue-shaped cut piece 5, and it does not come off from the back cover in any direction even when the cover is fully opened. However, if the document is turned with the front cover opened, the document can be easily detached from the tongue-shaped cut piece 5 and turned.
In addition, one direction of the document is left out, but the sheet adhering portion 8 is omitted, and the pocket is incomplete, but there is also a method of giving a margin to the number of files on the paper sheet. In the present invention, for the sake of convenience, the expressions front and back are used with Western books and documents in mind, and if a simple file dedicated to Japanese books and documents is considered, the expressions front and back and top and bottom are re-read in Japanese style. It is obvious that it is different from the present invention.

  In addition to the ultrasonic sealing and heat sealing, the sheet fixing portions 7 and 8 may be fastened with a stapler or the like as the simplest method. As shown in FIGS. 11 and fixing by the above method from the top of the cover is also possible. Of course, there is no problem even if the adhesive margin is reversed. Further, the tongue-shaped cut piece 5 as a document pressing member is provided by protruding the back cover as shown in the tongue-shaped cut piece 5a on the back cover 3 as shown in FIG. 6, and on the back cover as shown in FIG. It may be fixed as a tongue-like cut-out piece 5b to serve as a document pressing portion. Of course, it is also possible to bring another member and paste it.
