Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a file for efficiently organizing various forms.

<Prior art> There have been various types of bag-shaped files with openings at the top or sides, but all of them require a material that is thicker than necessary for strength and shape retention. We are in a situation where we have no choice but to use it. In other words, in cases such as the so-called vertical filing method in which a large number of files with open tops are stored and organized in a storage case of a certain depth, the forms stored in each file are taken out and used. Sometimes it is necessary to search for a desired form, but in order to keep the file itself standing straight without bending during this search process, the file must have a strong stiffness. Although it depends on the hardness and softness of the file material, in order to have strong "stiffness", it generally requires a certain thickness or more, and the thickness of the file material commonly used in the past is 0.2 mm even if it is thin. It has a thickness of 0.4mm because it is made up of two sheets forming a bag shape. On the other hand, ledgers such as resident records are approximately 0.08 mm thick, which is extremely thin compared to the file material, and the file material itself occupies a large proportion of the storage case, making it inefficient.

<Problems to be solved by the invention> The reason why a thick file material must be used as described above is that there is a problem with the shape of the file. In other words, a file that is shaped like a quadrilateral bag with one side or two adjacent sides open will inevitably have a weak "tightness."

<Means for solving the problems> In order to solve the above-mentioned problems, the present invention attempts to give a thin material strength by using folded parts. The gist of this is that a rectangular base material made of thin transparent plastic material is folded back from the upper and lower ends of one short side of the base material, and when the upper and lower ends are folded back, the upper and lower ends are placed above the midline in the vertical direction. The left and right ends of both folded pieces should be welded together, and the sides closer to the center line should be welded through the left and right sides from the upper and lower folded parts. This is a file for organizing business forms.

<Embodiments and Effects> The file of the present invention will be described in detail below with reference to the drawings showing the embodiments thereof.

FIG. 1 shows an embodiment of the file according to the present invention.
As shown in FIG. 1, the file of the present invention is made up of a single piece of backing material 1, an upper folded piece 2 whose upper end is continuously folded, and a lower folded piece 3 whose backing material and lower end are folded and continuous. This upper folded piece 2
and the lower folded piece 3 face each other on the front side with a slight interval above the vertical midline 4. The upper folded piece 2 and the lower folded piece 3
Both left and right sides are welded to the backing material 1 by side welds 5, and as shown in FIG. Also, the lower folded piece 3 is welded to the backing material 1 on the side slightly closer to the intermediate line 4 than the folded part at the lower end so as to form an upper welded part 6 and a lower welded part 7, respectively.

As shown in FIG. 3, the upper welded part 6 is formed about 1 cm below the upper folded part, and the upper welded part 6 is cut off at either the left or right side welded part 5, It is convenient during actual use if the cut-out opening is used as an index storage section 8 in which index pieces are taken in and taken out. Furthermore, the lower welded part 7 may also be located at a certain distance from the folded part of the lower part, and a binding hole 9 for binding files may be provided therebetween.

In the file of the present invention having the above structure, the form 10 is inserted through the upper opening of the lower folded piece 3 and stored between the lower folded piece 3 and the backing material 1, as shown in FIG. , organize a large number of such files in a storage case, or, in the case of a structure with binding holes 9 as shown in Figure 3, organize a large number of files by binding them together. It is something that does.

The file of the present invention, in which forms are stored in the state shown in Fig. 4, has folded parts at both the upper and lower parts, and furthermore, the upper and lower parts are located a little far from the upper and lower folded parts. Because the welded part is formed, a horizontally elongated hollow part is formed at the top and bottom, and this hollow part plays the role of a frame, making the entire file strong, and also allows the top and bottom folds to be folded. The part is resistant to damage and has a good texture when searching.

In manufacturing the file of the present invention, a ``fusion seal'' method is used in which both sides are cut and welded at the same time.

<Effects of the invention> As described above, according to the invention, the upper and lower parts are both folded parts, and the upper welded part and the lower welded part are formed, so that the file has a strong stiffness. Because of its excellent shape retention, it can be used even with very thin polyethylene films, such as 0.05 to 0.06 mm, and the occupancy of the file area in the storage case is reduced. It becomes possible to organize many forms.

In addition, since the upper and lower parts are folded parts, these parts are resistant to wear and are not easily damaged, and have a good feel when searching.
