Abstract

Provided is a file that can be selected from temporary binding and fixed binding as a binding method and that can be manufactured by a simple manufacturing process. Three or more protrusion-shaped objects are formed from a sheet-shaped molded article, and three are arranged so as to be paired around a fold line disposed in the protrusion-shaped article and the sheet-shaped molded article. One or more closed holes or closed slit-like structures 3, 4 or open holes or open slit-like structures 5 are formed by cutting into the sheet-like molding. [Selection] Figure 1

Description

  The present invention relates to a file suitable for binding and storing or transporting a plurality of sheets such as documents.

  A conventional file has a structure in which a thick sheet made of cardboard or synthetic resin is used as a cover material, and a tool having a binding mechanism made of metal or resin is combined. Therefore, the number of parts and the number of processing steps are complicated, which not only increases the manufacturing cost but also makes it unsuitable for separation and collection after use. Furthermore, since the conventional file is based on a structure that allows easy replacement of documents, it is easy to replace documents, but it does not have a function to prevent replacement, and has a simple structure and document There was no multi-functional file with a replacement prevention function.

  An object of the present invention is to provide a file and a binding mechanism that are simple and inexpensive in production process, and to provide a binding structure that can easily select a binding state in which replacement of materials is easy and a state in which binding is easy. . Furthermore, by selecting a material, it is easy to separate and collect, and to provide a file excellent in recyclability. In addition, an object of the present invention is to provide a file that is easy to store without being caught when the file is stored on a shelf, with the outer surface having a shape having no holes or slits, by a layer structure or a punching method.

  In order to solve the above-mentioned problems, in the present invention, a part of a cover material is processed to form a part constituting a binding mechanism and the like, and the processing is mainly performed by using a die cutting method. The product of the present invention can be provided at a low cost. There are no particular restrictions on the method of die cutting, such as making a die in advance and pressing it, or slitting or drilling with a laser beam or strong water flow. The present invention can be achieved by making a notch in the material.

  As shown in FIG. 1, the binding mechanism, which is a component of the present invention, passes the protrusion shape (2) through a hole such as a document, and then passes it through the hole or slit shape (3) of the opposing sheet piece (9). The bound material or the like is strongly fixed by passing the hole or slit shape (4) for fixing the protrusion-shaped object. Furthermore, if it passes a hole or slit shape (5), it can fix still more firmly. Further, when (5) is passed instead of passing (4), the protrusion-shaped object can be easily removed, which is suitable for temporary fixing. By using these binding mechanisms, it is possible to create the following many file forms, FIGS. 1 to 5, which are very useful.

  The arrangement of the binding mechanism of the present invention can be determined freely, but it is preferable to determine the number and arrangement of the binding mechanisms in consideration of the direction in which the material to be bound is opened. As a typical example, the arrangement of two binding mechanisms in the central part (FIG. 1) and the form (FIG. 2) arranged in the top part on the right side in an open state are representative. It is not limited to these, and it is possible to combine a plurality of these arrangements. In addition, the number of covers and the size of the cover can be changed as necessary, such as a two-fold shape, a non-folded sheet shape, a tri-fold shape of the fore edge, or a bellows-like fold shape.

  By forming the sheet-like molded product of the present invention into a multilayer structure and subjecting only a part of the inner layer to punching, the outer surface can be shaped without holes, slits, etc., and can be caught when storing files on a shelf. It is possible to provide a file that is easy to store without any problem.

  In the file of the present invention, when binding a thick document or the like to fold the cover, if a plurality of fold lines are provided, the file can be made to have an appropriate thickness by folding at the necessary fold line portion according to the thickness of the document etc it can. In addition, the length of the protrusion shape can be adapted to a wide range of applications by changing the length according to the required thickness. Further, when the number of binding mechanisms is increased in accordance with the weight of the material, for example, when the material has four holes (FIG. 3) and four binding mechanisms are provided, the force on each binding portion is dispersed. Therefore, it is effective for preventing omission of data.

  If necessary, the cover may be provided with a card pocket, a corner pocket (FIG. 4), a folded flap for protecting the data, etc. (FIG. 5). These accessories are not particularly limited in arrangement and position, and may be attached to the outside, inside, or both of the cover as necessary.

  The cover may be printed for various display purposes, or for the purpose of imparting writing ability, surface treatment, etc., especially when using transparent or translucent sheets, read the materials as necessary. By performing concealment printing, character design, and the like for prevention, product value can be further increased. In the case of a transparent sheet, by creating a transparent window portion, there is an effect that the information on the data surface can be used as a mailing address, and that it is easy to check the data when storing the file.

  The sheet used in the present invention is not limited to a single material such as a synthetic resin sheet, synthetic paper, non-woven fabric, recycled paper, resin-impregnated paper, etc. Different materials such as synthetic resin sheets, synthetic paper, non-woven fabric, recycled paper, resin-impregnated paper, etc. may be bonded, especially for materials with voids, such as non-woven fabric and paper. By improving the mechanical strength and water resistance, it is possible to create a material whose texture is changed by performing various known surface treatments. In particular, a known sheet material can be used for a sheet-shaped material as long as it can be punched, folded, and bent. When overlapping sheets, it can be used for the sheet base material of the present invention by performing a method of pasting the entire surface or a necessary part with an adhesive or a pressure sensitive adhesive or a method of pseudo-adhering a resin with heat or pressure. it can.

Using the binding mechanism of the present invention, after binding the materials, etc., it is possible to make it impossible to add or replace materials by attaching a tamper-proof seal etc. to the binding portion, and binding the cover part. Higher confidentiality can be maintained by pasting and sealing a tamper-proof seal or the like.
Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

Effect of device
