Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a document holder, in particular, it is difficult for dust to enter, and dust The document holder is easy to discharge quickly if it enters into.

[0002]

[Prior art]

  In the manufacturing process of precision electronic devices, foods, chemicals, etc. Dust becomes a factor that deteriorates the quality of the product when it mixes with the product, etc. It is important to take preventive measures against it, as it will lead to a decrease in luput and a decrease in the reliability of experimental results. ing. For example, the use of clean rooms, dust-free paper, and wearing dustproof clothing are the main preventive measures. It is a countermeasure.

[0003]   In this clean room work, work using multiple dust-free papers When using the document holder, make sure that the two sides are sealed and the two sides are open. With, it is easy to open and close the holder, and related documents can be stored together and carried again. It is extremely easy and convenient.

[0004]

[Problems to be solved by the device]

  However, you can use this holder for documents to When transporting documents between rooms, it is rather easy to open the inside, so instead use a clean room. Accumulate dust inside the holder inside the holder to transport the dust inside the clean room. On the contrary, the dust will be emitted inside the clean room, It was also a factor of pollution. In particular, the holder once accumulates dust inside it And the two sides of the edges are sealed, there is a problem that it is difficult to discharge to the outside. It   In addition, this type of holder has two open sides that have been opened with the passage of time. The phenomenon that the open on the outside of the holder occurs.

[0005]   Therefore, the purpose of the present invention is to prevent dust from entering without impairing the ease of transportation and opening. (EN) It is possible to provide a document holder that is easy to prevent and easily discharge dust that has entered.

[0006]

[Means for Solving the Problems]

  In order to solve the above problems, the document holder according to claim 1 of the present invention is Open in a vertically long holder that is made by folding a rectangular plastic sheet in two. In the vicinity of the two edges, the outside of the holder is the protruding side, which is parallel to the edges. It is characterized in that it has been pushed. In addition, the edge that is not pushed is Includes those that are completely sealed and those that are partially sealed. In addition, the streak push is pushed on all sides. You can do it, or you can press it on a part of it, or if you press the stripe on one side Then, you may press only a part of the stripe.

[0007]   The invention according to claim 2 is a vertically long plastic sheet having a rectangular shape folded in two. In the holder, inside the holder, near the two open edges, parallel to the edges. It is characterized in that a groove is provided in the portion. Make sure the open edge of the holder tilts inward In order to achieve the above, a groove is provided in place of the streak pressing in claim 1.

[0008]   The invention described in claim 3 is a vertically long plastic sheet having a rectangular shape folded in two. In the holder, near the one edge, the top is inside the holder and the edge is on the one edge side. Is provided with a plurality of triangular welding parts.

[0009]   The invention according to claim 4 is that the plastic sheet is a conductive sheet. Is characterized by. This conductive sheet is coated with a conductive material and kneaded Including both.

[0010]

[Action]

  According to the present invention, a vertically long holder obtained by folding a rectangular plastic sheet in two. , Press a streak in the vicinity of at least one open side in parallel with the open side. As a result, the one edge that has been streaked is tilted inside the holder. Prevents dust from entering the holder from the outside by overlapping the edges of the sheets Can be done.

[0011]   In addition, near at least one open side, the top is inside the holder and the end is By having multiple triangular welded parts on one end side, one end enters the holder The dust that has fallen is discharged from between the triangular welding portions.

[0012]   In addition, the plastic sheet is made of a conductive sheet, so that It is possible to prevent the dust collection effect due to the electrification of the rustic sheet and prevent the concentration of dust. It becomes Noh.

[0013]

[Embodiment of device]

  An embodiment of the present invention will be described below with reference to the attached FIGS.

[0014]   The holder 1 according to the present invention is a rectangular plastic sheet as shown in FIG. 2 is bent at the end 4, and one of the remaining 3 sides of the end is welded and sealed. And is composed of ends 8 and 10 with the remaining two sides open. 8 ends And 10 are streaked at a position 5 to 10 mm from the end parallel to the ends 8 and 10. 12 and 16 are provided.

[0015]   The streak pushers 12 and 16 are provided from the folded inside of the plastic sheet 2 to the outside. It is pressed so as to project to the side. Therefore, push the plastic sheet 2 It bulges outward at 12 and 16 and, on the contrary, acts to close at the ends. Also, press the line The contacts 12 and 16 are parallel to the ends and have an R and are connected to each other.

[0016]   One of the remaining three edges is welded, and the edge is specifically a triangular welded portion 1. A plurality of 8a to 18e are arranged at specific intervals so that the center of the holder 1 is the apex. Arranged. The space between the welded portions 18a to 18e is open, and the welded portions 18a are Only the positions of ~ 18e are welded.

[0017]   Since the welded parts 18a to 18e are of a triangular shape, dust inside the holder 1 is easily removed. Is discharged to the outside.

[0018]   Next, a method of making the present invention will be described with reference to FIG. First of all, large format plastic Holder that cuts the plastic sheet according to the present invention from the stick sheet Cut out for.

[0019]   Secondly, 12, 14a, which corresponds to the central end 4 and the streak pushes 12, 14, 16; The lines 14b, 16a, 16b are pushed.

[0020]   Thirdly, it is completed by bending the edge 4 at the center and welding the remaining edge with a triangular shape. Become.

[0021]   Further, FIG. 3 shows a second embodiment in which the shape of the line pushing is different. With the first embodiment The difference is that the streak pushers 20 and 22 are not connected at the corners of the holder 1. It is something.

[0022]   It should be noted that the present invention is not limited to the above-described embodiment, and for example, the line pusher 2 4 is replaced by a groove (Fig. 4), etc. It is included in the device.

[0023]
