Description

  clear file.

  clear file

The bottom part of the known clear file hurts when holding it, and when a lot of documents are put, the bottom joint 3 is broken. Also, since there is no bottom joint 4 directly below, a clip, a bottle, etc. may fall from here, or the joint 3 may break from this (30) or not to bond the part 4 in manufacturing, or the tear prevention die cut 5 Also, since a punching process of the insertion die cut 6 is required, the manufacturing process is required, and the cost is increased.

The folds and the seams are rotated by 90 ° so that the non-joining portion 4 is made horizontal and the die cutting is not performed, so that the performance is improved and the cost is reduced.

  Since the insertion part is slightly open, there is no need to put a finger in the notch to open the document one by one, and there is no need to store the document to be inserted. There is no risk of cutting the hand at the end, especially when putting in and lifting many documents, the number of processes is reduced in manufacturing, and the cost is low, and a clear file easy to be mass-produced is obtained.

FIG. 1 shows a known clear file 1, which comprises a fold 2, a joint 3, a breaking slit 4, and a document insertion turning recess 5.
FIG. 2 is a cross-sectional view of a known file, and since the junction 3 is at the bottom, two holes of the front and back of the main body 1 are attached, so the hole 5 to be turned is required.
FIG. 3 is a cross-sectional view of the clear file 1 in the case where a large number of documents 6 are put in the known clear file 1, and a slit 4 for preventing the seal 3 from breaking is inserted. I will leave.

FIG. 4 shows an embodiment of the clear file according to the present invention, and the main body 7 does not need the cuts 5 and 6. This is because the body 7 and the edge 12 are always slightly open since there is no joint 3 at the lower end of 7 as in the side view of the invention of FIG. The joint 9 is longitudinal and is provided below it with a part 10 without joints. Reference numerals 11 and 12 denote cut portions on the left and right sides.
As shown in FIG. 6, even if a large number of documents 6 are inserted, the eight parts are rounded and correspond, so the file 7 is not destroyed.

FIG. 7 shows a manufacturing line for manufacturing the device of the present invention, which is subjected to a process 71 of folding the clear file original sheet 70 into a triangular shape, and the sheet is creased by a pinch roller 81 (rotation shaft is 82) rotated by a motor 83. It is bent and sent 72. Next, bonding 9 is performed in the longitudinal direction by the bonding device 90. In the bonding apparatus, as shown in FIG. 7, the bonding spot 91 does not have the full width 90, and the lower end 92 is not provided with a bonding portion. By doing this, as shown in FIG. 4, it is possible to provide a portion 10 without bonding at the lower end of the bonding portion 9.
As the sheet 72 further advances, it is cut in the longitudinal direction by the cutter 110, and the product 7 of the present invention is completed. Then, it falls into the cutter 14 and the finished product 7 is automatically stacked.

  Clear File is a necessity that is used in all workplaces, homes and schools. According to the present invention, it is hard to break, easy to turn over, contains a lot of treatments, is not injured in the hand, and is low in cost and therefore industrially applicable.
