BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file in which documents are stored in parallel pockets.

[0002]

2. Description of the Related Art In a conventional file, as shown in FIGS. 4 and 5, a pair of cover sheets 2 and 2 facing each other which are bendable via a bottom sheet 1 made of a synthetic resin are formed in series, and one cover sheet is formed. A flexible lid sheet 3 is connected to the upper edge of the sheet 2, and two end sheets 4 of synthetic resin are bent in a zigzag shape by fold lines 5 arranged at equal intervals in parallel with the edge, and both cover sheets are formed. Both end edges of the end sheet 4 are heat-bonded to both side edges of the facing surfaces of the sheets 2 and 2, and further, both side edges of each partition sheet 6 of synthetic resin are heat-bonded 7 to the surface between the fold lines 5 of the end sheet 4. .

[0003]

The end sheet of the file as described above is a synthetic resin sheet having elasticity, so heat is applied to the crease line forming position by a pressing die and then the part to which the heat is applied is immediately bent by hand. If it does not form a polygonal line, it cannot be bent in a zigzag shape. For this reason, there is a problem that processing is remarkably troublesome and inefficient and cost is increased.

Therefore, an object of the present invention is to provide a file capable of bending the end sheet in a zigzag shape very efficiently.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention forms a pair of facing cover sheets that are bendable and is opposed to each other through a bottom sheet of synthetic resin, and also comprises two synthetic resin sheets. The end sheet is bent in a zigzag shape by fold lines that are parallel to the end edge and is zigzag-shaped, the both end edges of the end sheet are fixed to both side edges of the facing surface of the both cover sheets, and further, a plurality of partition sheets arranged in parallel. In a file formed by attaching both side edges to the end sheet, perforations are formed at equal intervals between the both end edges of the end sheet, and the perforation is formed as a broken line.

[0006]

[Function] The end sheets are bent in a zigzag shape by perforations arranged in parallel.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a synthetic resin bottom sheet 1
1. Both side edges of the cover sheet 1 have flexible cover sheets 12 facing each other,
12 are coupled.

Further, on the upper edge of one cover sheet 12,
A bendable lid sheet 13 is formed in series.

Reference numeral 14 is a polygonal line 15 at equal intervals parallel to the edge.
Two synthetic resin end sheets bent in a zigzag shape by
It is firmly fixed to both side edges of the facing surface of the No. 2.

Reference numeral 16 is a plurality of partition sheets arranged in parallel, and both side edges of each of the partition sheets 16 are end sheets 14.
It is attached to.

A partition sheet 16 for the end sheet 14
2 and 3, the inverted L-shaped engaging pieces 17 are projected from both side edges of the partition sheet 16 (the number of which is not limited), and the engaging pieces 17 are attached to the end sheets. 14
In the slit 18 (the slit 18 is provided on the broken line 15 in the illustrated case, but may be provided between the broken lines 15)
After that, the partition sheet 16 is moved downward to prevent the engaging piece 17 from coming out of the slit 18, or the side edge of the partition sheet 16 is heat-bonded to the end sheet 14.

Further, in order that the end sheet 14 can be bent in a zigzag shape very easily, each of the fold lines 1
A perforation 19 has been put in advance on the forming line of No. 5, and the perforation 19 makes it very easy to bend and
It is possible to form the polygonal line 15 that is bent in a zigzag shape by a hand or the like.

If a U-shaped inversion feed (not shown) is provided at the end of each perforation 19 so as to be continuous from the end of the perforation 19 (not shown), a tear is formed at the end of the perforation, and a broken line is formed. The inconvenience is solved so that the portion 15 is cut.

[0015]

[Effect] As described above, according to the file according to the present invention, since the perforations that are juxtaposed to the end sheet are provided, it is extremely easy for the perforations to bend the zigzag shape by bending the crease lines. You can

For this reason, the laborious work of bending the end sheets in a zigzag shape while heating and bending by hand becomes unnecessary.

Claims (1)

[Scope of utility model registration request] 1. A synthetic resin bottom sheet is formed between a pair of opposing cover sheets that can be bent, and two synthetic resin end sheets are formed in a zigzag shape by fold lines parallel to the end edges. In a file formed by bending and fixing both end edges of the end sheet to both side edges of the facing surface of both cover sheets, and further attaching both side edges of a plurality of partition sheets arranged in parallel to the end sheet, A file characterized in that perforations are inserted at equal intervals between both edges, and the perforations are formed as broken lines.
