Abstract

(57) [Summary] [Purpose] To make it possible to easily bend the end sheet of a file in a zigzag shape. [Structure] A perforation line 19 parallel to an end sheet 14 in a file is inserted, and the end sheet is bent in a zigzag shape by the perforation line.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a file in which documents are stored in parallel pockets.

[0002]

[Prior Art]

 As shown in FIG. 4 and FIG. 5, the conventional file is composed of a pair of cover sheets 2 and 2 which are bent and opposed to each other via a synthetic resin bottom sheet 1, and the upper edge of one of the cover sheets 2 is formed. A flexible lid sheet 3 is connected to the above, and two synthetic resin end sheets 4 are bent in a zigzag shape at the equally-spaced crease lines 5 parallel to the edges thereof to form the cover sheets 2 and 2 Both end edges of the end sheet 4 are heat-bonded to both side edges of the facing surface, and both side edges of each synthetic resin partition sheet 6 are heat-welded 7 to the surface between the fold lines 5 of the end sheet 4.

[0003]

[Problems to be solved by the device]

 The end sheet of the above file is a synthetic resin sheet with elasticity, so after applying heat to the crease line forming position by the die, immediately bend the heated part by hand to form the crease line. It cannot be bent in a zigzag shape. For this reason, there is a problem in that machining is extremely time-consuming and inefficient, resulting in an increase in cost.

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]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a pair of cover sheets facing each other in a bent and independent manner via a synthetic resin bottom sheet, and also two end sheets of synthetic resin are arranged in parallel to the edges. Bend it in a zigzag shape with equally spaced fold lines, fix both end edges of the end sheet to both side edges of the facing surface of both cover sheets, and further set both side edges of a plurality of parallel partition sheets to the end sheet. In the file to be attached, perforations are inserted at equal intervals between the both edges of the end sheet, and the perforations are formed as a polygonal line.

[0006]

[Action]

 Bend the end sheet in a zigzag shape with the perforations in parallel.

[0007]

【Example】

 An embodiment according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, flexible cover sheets 12 and 12 that face each other are formed on both side edges of a synthetic resin bottom sheet 11.

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

Reference numeral 14 is an end sheet made of two synthetic resins bent in a zigzag shape by fold lines 15 that are parallel to the end edges, and both ends of the end sheet 14 are opposite edges of both cover sheets 12 and 12. It is stuck to.

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

To attach the side edges of the partition sheet 16 to the end sheet 14, as shown in FIGS. 2 and 3, the inverted L-shaped engaging pieces 17 (the number of which is limited are provided from both side edges of the partition sheet 16. Projecting, inserting the engaging piece 17 into the slit 18 of the end sheet 14 (the slit 18 is provided on the broken line 15 in the drawing, but may be provided between the broken lines 15), and then downwardly. The partition sheet 16 is moved to prevent the engaging piece 17 from coming out of the slit 18, or the side edge of the partition sheet 16 is thermally attached to the end sheet 14.

In addition, in order that the end sheet 14 can be bent in a zigzag shape very easily, perforations 19 are provided in advance on the formation lines of the respective fold lines 15, and the perforations 19 make it very easy to fold. It is possible to form the polygonal line 15 that bends in a zigzag shape by hand or the like.

If a U-shaped inversion feed (not shown) is provided continuously from the end of each perforation 19 and the end of each perforation 19 (not shown), a tear can be formed from the end of the perforation. The inconvenience is solved so that the part of the polygonal line 15 is cut.

[0015]

【effect】

 As described above, according to the file according to the present invention, since the perforations that are arranged in parallel with the end sheet are provided, it is possible to bend the zigzag shape with the fold lines very easily by the perforations.

For this reason, the laborious work of bending the end sheet in a zigzag shape while bending the hand while heating is unnecessary.

Claims (1)

[Scope of utility model registration request] 1. A synthetic resin bottom sheet is formed between a pair of bendable opposite cover sheets, 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 sheets of the 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.
