2. Description of the Related Art Recently, one resin sheet is folded into two front and back thicknesses to form a bottom portion, the left and right sides of the bottom portion are formed as side portions, and the opposite side of the bottom portion is an open portion. There is known a folder that can store various documents inside.

Known folders include, for example, FIG.
There are types shown in. Same folder 50
Is formed in a bag shape in which a synthetic resin sheet is folded in two to form a bottom portion 51, side portions 52 and 52 are provided on both left and right sides of the bottom portion 51, and an upper portion is an open portion 53. . The upper ends 52A of the side parts 52, 52 have a height that is located approximately in the middle between the bottom part 51 and the open part 53,
From the upper ends 52A, 52A of the side parts 52, 52 to the open part 5
The respective surfaces of the front and back sheets S1 and S2 between the sheet 3 and the sheet 3 can be brought into close contact with each other or separated from each other. Therefore, documents can be taken in and out by opening the upper and lower surfaces of the front and back sheets S1 and S2 so as to separate them.

[0004]

However, in such a folder 50, since a resin sheet is used as the molding material, when the opening portion 53 is wide opened to take in and out a document. , Front and back sheets S1,

There is an inconvenience that a large load is applied to the position of the upper end 52A of No. 2 or in the vicinity thereof and the region near the upper end 52A is easily broken. Further, in order to prevent such breakage, it is necessary to use a relatively soft resin sheet, which restricts the materials used and also brings about the inconvenience that the degree of freedom in design is narrowed. Furthermore, when a hard resin sheet is used, it becomes difficult to fold it, and if it is forcibly bent, there is a disadvantage that clouding occurs in the bent portion.

Further, the folder 50 has the disadvantage that the document may come out from the opening 53 when it is held upside down, and it is already stored when it is stored in a box file or the like. It also has the inconvenience of being in another folder.

[0006]

SUMMARY OF THE INVENTION The present invention has been devised in view of such disadvantages of the conventional example, and an object thereof is to bend and deform the front and back sheets without difficulty when loading and unloading documents and the like. It is an object of the present invention to provide a folder that can effectively prevent such problems and can alleviate restrictions on materials used.

Another object of the present invention is to provide a folder which eliminates the possibility that a stored document will come out and which does not enter the other folders already stored when storing the folder in a box file or the like. To do.

In order to achieve the above object, according to the present invention, one side of a resin front and back sheet is a bottom portion, and both left and right sides connected to the bottom portion are side portions, and the opposite side of the bottom portion is In a bottomed bag-shaped folder formed as an upper opening, the left and right side portions are provided at a height such that their upper ends are located between the bottom portion and the upper opening portion, and the upper ends of these side portions or A folding line is provided on at least the back sheet surface between adjacent positions. With this configuration,
When trying to open the upper open side, the back sheet bends reasonably and greatly, creating a space where documents can be easily taken in and out, and reducing the load that can occur in the upper side area of the side and tearing etc. Can be prevented. Moreover, when the upper open portion is opened, the upper portion of the bending line is displaced so as to bend with respect to the lower portion, so that a relatively hard resin sheet can be used.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the folder, a lid piece having a front end directed to a bottom portion is provided on an inner surface side of an upper portion of the back sheet, and the lid piece is provided in a substantially central region of the back sheet in the left-right direction. At the same time, it is possible to adopt a configuration in which it is provided so as to overlap the upper surface of the front sheet. Thus, by setting the lid piece so as to overlap the front surface of the front sheet, the upper side of the front and back sheets is closed, and the documents stored inside can be prevented from falling off. Moreover, since the lid piece is provided substantially in the center of the back sheet in the left-right direction, that is, since the lid piece is not provided at a position shifted to the left or right of the back sheet, the storage flat area of the folder is reduced. On the other hand, even a document having a considerably small flat area can be effectively prevented from falling off.

Further, on the upper side of the back sheet, a heading pocket formed by folding the backing sheet into a double-thickness is provided over the entire width of the left and right sides, and the lid piece is formed continuously in a substantially central region of the heading pocket. It is advisable to adopt the configuration of being performed. With such a configuration, classification and storage can be performed easily, and the strength of the upper side of the back sheet can be increased.

In this specification, the table is used for the surface side shown in FIG. 1, that is, for the surface on the side where the lid piece is located in the closed state. Further, the back side is the opposite side, and is specifically used for the surface side shown in FIG.
