Abstract

(57) Abstract: In a synthetic resin file having a file binding device (20) inside, an insertion rod (21) is integrally formed below the file binding device (20), and a through hole (1) is formed in the file cover (10).
The end of the insertion rod 21 inserted into the through hole 11 is heated to provide a rivet head-shaped locking portion 22. [Effect] It is easy to manufacture. There is no need to separate the synthetic resin material and the metal material, and disposal can be performed easily.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a file used for binding various punched documents, and more particularly to a file which is easy to manufacture and can be easily disposed of.

[0002]

[Prior art]

 Generally, this type of file is composed of a file cover made of synthetic resin and a file binding device. For example, in the conventional file shown in FIGS. 4 and 5, through holes 41 and 51 are formed between the file cover 40 and the file binding device 50, and a metal rivet 60 is provided in each of the through holes 41 and 51. After the fitting, the tubular end portion 61 of the rivet 60 protruding from the through hole 51 on the file binding device 50 side is crushed by a press, so that the file cover 40 and the file binding device 50 are connected. .

[0003]

[Problems to be solved by the invention]

 Since such a conventional file is connected using rivets 60, there are problems that the number of manufacturing steps is increased, the manufacturing cost is high, and the productivity is low.

[0004] Further, when discarded after use, the file cover 40 and the file binding device 50 are made of synthetic resin, and the rivet 60 is made of metal. If it is not removed from the binding device 40 or the file binding device 50, the separation process cannot be performed, and this removal work is extremely troublesome.

Therefore, the present invention has been devised to solve the above-described problem, and has as its object to provide a file that can be easily manufactured and can be easily disposed of.

[0006]

Means for Solving the Problems In order to achieve the above object, a means of the present invention is to contact a file cover 10 of a file binding device 20 in a synthetic resin file having a file binding device 20 inside. An insertion rod 21 is integrally formed on the side surface, a through-hole 11 is formed in the file cover 10, and an end of the insertion rod 21 inserted through the through-hole 11 is heated to form a rivet head-shaped engaging portion. The provision of 22 is a means for solving the problem.

[0007]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 to 3 show an embodiment of a file binding device of the present invention. The files illustrated in these drawings are composed of a file cover 10 formed of synthetic resin, and a synthetic resin file binding device 20 connected to the inside of the file cover 10.

The file binding device 20 has a synthetic resin insertion rod 21 protruding from a side surface in contact with the file cover 10 (see FIG. 1). The insertion rod 21 may be formed integrally with the file binding device 20 or may be formed by joining the synthetic resin insertion rod 21 to the synthetic resin file binding device 20. The illustrated insertion rod 21 is formed as a pair at both longitudinal ends of the file binding device 20.

The file cover 10 has a through hole 11 through which the insertion rod 21 is inserted (see FIG. 1). When the insertion rod 21 is passed through the through hole 11, the end of the insertion rod 21 projects from the file cover 10 side (see FIG. 2).

By heating and crushing the end of the protruding insertion rod 21, the end of the insertion rod 21 is formed like a head shape of a rivet, and a locking portion 22 is provided. The front cover 10 and the file binding device 20 are connected (see FIG. 3).

Note that the file binding device 20 in the illustrated example shows a type that binds two-hole paper, but the file binding device 20 is not limited to the illustrated example. Any type of file binding device 20 may be used as long as the file binding device 20 is made of a synthetic resin, such as a device (not shown).

[0012]

[Effect of the invention]

 In a synthetic resin file having a file binding device 20 inside, a synthetic resin insertion rod 21 is formed on a side surface of the file binding device 20 that is in contact with the file cover 10, and a through hole 11 is formed in the file cover 10. Since the end of the insertion rod 21 inserted into the through-hole 11 is heated to provide the rivet head-shaped locking portion 22, the file cover 40 and the file binding device 50 are connected to each other as in the related art. Since the step of fitting the metal rivet 60 is not required, the production can be shortened and the production cost can be reduced.

Further, since the file cover 10, the file binding device 20, and the insertion rod 21 are all formed of a synthetic resin material, only the metal rivet 60 is removed when discarding as in the prior art. The waste can be separated and recycled without the hassle of having to do so.

As described above, according to the present invention, it is not necessary to separate the synthetic resin material and the metal material, and various effects such as easy production and easy disposal can be achieved.
