Description

Clear file {Clear file}

The present invention relates to a clear file, more specifically to a clear file which can be folded into a pocket structure so that documents stored therein can not be easily removed, and which is simple in structure and easy to manufacture.

The clear file is used for conveniently storing a sheet-like paper document, a document, a receipt (collectively referred to as "document" hereinafter), and has a structure in which one side and the other side in the width direction are opened . That is, the two sheets of transparent sheets are combined so that only the lower side and the other side in the width direction are combined to have the opening of the 'A' shape.

The transparent sheet constituting the clear file is made of polypropylene (PP) and has a very thin film form for light weight. When the clear pile is made of a thin transparent sheet, the flexibility is high and it can be bent very easily. There is a disadvantage in that the document inserted between the transparent sheets of the sheet can easily fall outside.

In particular, if the opening portion of the clear file is formed in the letter 'A' shape, a pair of transparent sheets that are overlapped with each other can be easily opened, and the document that has been drawn into the inside can be easily removed.

In order to solve such a problem, a clear file having a separate fixing unit such as a rubber band or a clip has been proposed on the side of the pair of transparent sheet openings. However, in order to add the fixing unit, So that the weight of the product can not be reduced. In addition, in order to manufacture a clear file to which the fixed unit is added as described above, a process of manufacturing a transparent sheet and attaching the fixed unit after the transparent sheet has been added must be added. Thus, the overall manufacturing process of the product becomes complicated, There is a problem that the manufacturing cost is remarkably increased.

2 and 3 are a front view and a perspective view of the clear file according to the present invention.
Figs. 4 and 5 are diagrams showing the state of use of the clear file according to the present invention. Fig.

Hereinafter, an embodiment of a clear file according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a developed view of a clear file according to the present invention, and FIGS. 2 and 3 are a front view and a perspective view of a clear file according to the present invention.

The clear file according to the present invention is a kind of stationery for conveniently storing a sheet-like paper document, a document, a receipt (hereinafter referred to as "document"), and the like. But it can be folded into a pocket structure so as to prevent the document stored therein from being pulled out against the user's intention.

That is, the clear file according to the present invention comprises: a base sheet 100 having a rectangular shape; a base sheet 100 connected to one end in the width direction of the base sheet 100 and folded to cover one surface of the base sheet 100, And a second cover sheet 200 connected to the other end in the width direction of the base sheet 100 and folded to cover one surface of the first cover sheet 200 And an upper sheet 400 connected to an upper end of the base sheet 100 and folded to cover a part of the upper surface of the second cover sheet 300. The base sheet 100, the first cover sheet 200, the second cover sheet 300, and the upper sheet 400 are made of a material having transparency higher than a reference value so that the documents stored therein can be exposed to the outside And it is manufactured in the form of a thin film to lighten the product.

In this case, the base sheet 100 and the first cover sheet 200, the second cover sheet 300, and the upper sheet 400 may be separately manufactured and then joined together. However, in such a case, The first cover sheet 200, the second cover sheet 300, and the upper sheet 400 may be fabricated into a single film and then folded along the boundary line between the sheets . 1, since the base sheet 100 and the first cover sheet 200 are coupled to each other at the lower ends thereof, the base sheet 100 and the first cover sheet 200 are bonded to each other at the lower end of the first cover sheet 200, An adhesive region 10 is provided.

The user pulls the document between the base sheet 100 and the first cover sheet 200 and stores the document. When the space between the base sheet 100 and the first cover sheet 200 is opened only on the upper side like a general pocket structure The space between the base sheet 100 and the first cover sheet 200 is difficult to enter the document between the base sheet 100 and the first cover sheet 200. Therefore, The left side in FIG.

Since the base sheet 100, the first cover sheet 200, the second cover sheet 300 and the upper sheet 400 are all made of a polypropylene (PP) film having high ductility, as described above, If the opening of the space between the first cover sheet 100 and the first cover sheet 200 is left untouched, the base sheet 100 and the first cover sheet 200 can be easily opened, and the stored document can be released. However, the clear file according to the present invention is additionally provided with the second cover sheet 300 and the upper sheet 400 covering the left opening portion and the upper opening portion between the base sheet 100 and the first cover sheet 200 There is an advantage that a document stored between the bar and the base sheet 100 and the first cover sheet 200 can not be easily drawn out to the outside.

Since the second cover sheet 300 and the upper sheet 400 are separated from the base sheet 100 (100) without a separate fixing device, since the polypropylene (PP) film has a property of keeping the folded state at a certain level when folded by external force, And the first cover sheet 200, as shown in Fig. However, when a large external force is applied to the folded second cover sheet 300 or the top sheet 400 or when the user strongly shakes the clear file according to the present invention, the second cover sheet 300 and the top sheet 400 The base sheet 100 and the first cover sheet 200 may spread between the base sheet 100 and the first cover sheet 200, resulting in a phenomenon that the document is pulled out.

Therefore, the clear file according to the present invention can be configured such that the folded state of the second cover sheet 300 and the top sheet 400 can be maintained so as to solve such a problem. That is, the protruding portion 410 is formed on the upper sheet 400 through a process of forming a convex bowing toward the upper end of the base sheet 100, and the first cover sheet 200 and the second cover The sheet 300 may be provided with a first insertion incision improvement 210 and a second insertion incision improvement 310 into which the protrusion 410 is inserted. The second cover sheet 300 and the upper sheet 400 may be fixed in a folded state when the protrusion 410 and the first insertion incision 210 and the second insertion incision 310 are provided, The structure in which the folding of the second cover sheet 300 and the top sheet 400 are fixed will be described in detail with reference to FIGS. 4 and 5. FIG.

In addition, since the conventional clear file is simply formed in the shape of a rectangular sheet, there may be a difficulty that the user can not quickly select the clear file desired by the user when a large number of the clear files are stacked. Of course, it is possible to directly check the kind of the clear files while widening each clear file, but in this case, it takes a long time to sort and select the clear files.

The clear file according to the present invention has another feature in that it has an index unit 220 to solve such a problem. If the index part 220 is separately manufactured and attached to the clear file, it takes a lot of time and expense to manufacture the index part 220. Therefore, the index part 220 can be easily attached to the first cover sheet 200, (In the present embodiment, the right side direction) away from the base sheet 100 at a portion of the base sheet 100 that is connected to the base sheet 100. As shown in FIG.

1, when the folded index portion 220 is formed at a portion of the first cover sheet 200 that is connected to the base sheet 100, the first cover sheet 200, The index part 220 protrudes sideways from the fold line of the first cover sheet 200 when the cover 220 is folded so as to cover one side of the base sheet 100, By specifying the name of the clear file, you can find the clear file you want easily and quickly.

Figs. 4 and 5 are diagrams showing the state of use of the clear file according to the present invention. Fig.

When a document is stored in the clear file according to the present invention, the document is stored between the base sheet 100 and the first cover sheet 200. The space between the base sheet 100 and the first cover sheet 200 is As shown in FIG. 3, since the opening is formed not only on the upper side but also on the left side, a document inserted between the base sheet 100 and the first cover sheet 200 may be pulled out. A second cover sheet 300 covering the left opening between the base sheet 100 and the first cover sheet 200 and a second cover sheet 300 covering the base sheet 100 and the first cover sheet 200. [ The second cover sheet 300 and the upper sheet 400 can be separated from each other even if the second cover sheet 300 and the upper sheet 400 are provided as described above. The opening between the base sheet 100 and the first cover sheet 200 is opened so that the document inserted between the base sheet 100 and the first cover sheet 200 can be released to the outside.

The clear file according to the present invention has a structure in which the folded second cover sheet 300 and the top sheet 400 are folded so as to close the opening between the base sheet 100 and the first cover sheet 200, The first cover sheet 200 and the second cover sheet 300 are provided with protrusions 410 on the first cover sheet 400 and the first insertion incision improvement 210 and the second insertion section improvement 300 on which the protrusions 410 are fitted, There is another feature in that the second electrode 310 is formed. Accordingly, the user inserts the document between the base sheet 100 and the first cover sheet 200, and then folds the second cover sheet 300 as shown in FIG. 4, The sheet 400 is folded to insert the projection 410 into the first insertion incision improvement 210 and the second insertion incision improvement 310. [

When the protrusion 410 is inserted into the first insertion incision 210 and the second insertion incision 310, the second cover sheet 300 and the upper sheet 400 are not unfolded, The first cover sheet 200 and the first cover sheet 100 are not separated from each other, so that the document can be prevented from falling to the outside. At this time, if the extension of the second cover sheet 300 and the top sheet 400 can be prevented even if the protrusion 410 is inserted only in the second insertion incision improvement 310, the first insertion incision improvement 210 is omitted . In addition, when the second cover sheet 300 and the upper sheet 400 are not easily expanded when they are folded, the protrusions 410 and the first insertion incision 210, the second insertion incision 310, May all be omitted.
