DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filing member used for sorting and carrying documents.
In particular, the present invention relates to a filing member that prevents a document from falling off the filing member.

[0002]

2. Description of the Related Art Conventionally, paper or plastic filing members, which are referred to as clear files and holders, for holding documents for carrying and sorting, have been widely used. Such a filing member is one in which a document is sandwiched between two plastic films joined on two sides, one provided with a pocket on one of two sheets joined on one side, and one joined on one side There are various types such as one in which one or both of the two sheets are provided with a fitting for binding a document.

[0003]

However, in the case where the two sides are simply joined or the case where a pocket is provided, there is a problem that a document sandwiched by the filing member is easily dropped depending on the angle and the state of the filing member. On the other hand, the type that binds a document to a binding tool requires time and effort to bind the document, and the document cannot be easily taken out from the filing member.

Accordingly, an object of the present invention is to provide a filing member which can securely hold a document and can be easily taken out.

[0005]

According to the present invention, there is provided a filing member comprising: a sheet-like member having a pair of sheet portions for sandwiching a document; and a pressing member fixed to at least one of the sheet portions. A filing member, wherein the holding member is made of a material that can be electrostatically attracted.

[0006] By sandwiching the document between the sheet-like member and the holding member and rubbing the document with the holding member two or three times, the surface of the holding member is charged, and the electrostatic attraction force causes the sheet to become a sheet. It is gripped between the shape members. The document is securely held without falling off from the filing member by the gripping force due to the electrostatic attraction. Moreover, when taking out the document from the filing member, the document can be easily taken out simply by peeling off the pressing member from the document.

Further, in the filing member of the present invention, friction is generated between the document and the pressing member due to vibration generated when the filing member is carried, and is attracted. Therefore, even when the work of rubbing the document with the pressing member is not particularly performed, the suction force is ensured.

As the electrostatically adsorbable material, it is preferable to use an electrostatic adsorbent in which a porous or porous layer made of an electrostatically chargeable polymer is formed on a support. Strong adsorption power is obtained.

Various methods can be adopted for the shape of the holding member and the method of fixing the holding member to the sheet portion.
It may be a pocket-shaped one with three or three sides fixed or a strip-shaped one. In the case of a strip, one side may be fixed to the sheet-like member, or two opposing sides may be fixed.

[0010] The sheet member can also be made of a material that can be electrostatically attracted. In this case, the entire sheet-shaped member may be made of a material capable of electrostatic attraction, or a part thereof may be made of a material capable of electrostatic attraction.

The filing member 10 comprises a sheet-like member 1 and a pressing member 2, and Is composed of two sheets 1a and 1b for sandwiching the document 20, and one end of the pressing member 2 is fixed to one of the two sheets. In the figure, reference numeral 3 denotes a fixed portion (joined portion). The pressing member 2 is made of a material that can be electrostatically attracted, and the document 20 is held between the sheet-like member (sheet) and the pressing member 2 using the electrostatic attraction force.

The sheet-like member 1 may be a sheet obtained by folding a single sheet substantially at the center or a part obtained by joining a part of two sheets.

As a method of joining two sheets at a part, for example, joining one side end or two side ends of the sheet to another sheet can be mentioned. It is also possible to adopt a method in which a portion is joined to the other sheet in a dot shape. Further, the portion to be joined may be anywhere, such as the upper end, right end, or left end of the sheet. As a means for joining, there are a method of bonding with an adhesive, an adhesive, a double-sided tape, and a method of dissolving a part of a film or a substrate with heat fusion, ultrasonic fusion, a solvent, or the like. is there.

[0015] A spine or "gusset" may be provided at the folded or joined portion.

The material forming the sheet-like member 1 is not particularly limited as long as it has appropriate rigidity for holding a document. For example, paper, coated paper, polyester, polyethylene, polycarbonate, polychlorinated Vinyl, polyvinylidene chloride, polyacrylonitrile, AB
A resin sheet such as S, nylon, polypropylene, and polystyrene can be used. It may be a transparent material so that the contents of the document can be checked. It is also possible to use the same material that can be electrostatically attracted as the pressing member 2 described later.

The outer surface of the sheet-like member 1 may have a writing property. When the surface of the sheet-like member 1 has no writability, the writability can be imparted by providing a known writing layer. For the writing layer, use a water-based or oil-based pen to write with a whiteboard writing layer that can be erased by wiping or white ink, a layer that can be written with white ink that can be erased by wiping, a trace layer that can be written with a pencil or pen, etc. There is. When the writing layer is formed by coating, a coating solution obtained by dissolving or dispersing the material constituting the writing layer in a suitable solvent, for example, a bar coater, a gravure coater, a curtain coater, a roll coater, a blade coater, etc. It can be formed by coating and drying with a coating device.

By providing such a writing layer, characters can be written on the surface of the sheet-like member 1. Especially when the material for providing the writing layer is a transparent material,
While visually recognizing the document sandwiched between the sheet-like members, it is possible to write on the document from the transparent material without soiling the document.

On the inner surface of the sheet-like member 1, a transfer preventing process can be performed so that transfer of ink or toner printed on a document or the like does not occur.

The holding member 2 is made of a material having an electrostatic attraction force by frictional charging, and any material may be used as long as at least a surface holding a document has an electrostatic attraction force by frictional charging. As such a material capable of electrostatic attraction, a material having electrostatic attraction itself, or a material having a layer having electrostatic attraction formed on a sheet-like or plate-like material can be used.

Examples of the material which can be electrostatically adsorbed by itself include, for example, polyvinyl chloride film containing an organic ketone having 40 to 60 carbon atoms, polyvinyl chloride film containing an organic tin-based stabilizer, and polypropylene film. .

As the electrostatic attraction layer, there is a porous or porous layer made of an electrostatically chargeable polymer. Such an electrostatic attraction layer has a strong electrostatic attraction and a strong document holding power. This is particularly preferred. Examples of the polymer capable of electrostatic charge include, but are not particularly limited to, acrylic resin, vinyl chloride / vinyl acetate resin, vinyl chloride / vinyl acetate / maleic acid resin, styrene / acrylic resin, acrylic / vinyl chloride resin, unsaturated polyester, chloride Rubber, vinyl acetate resin, cellulose acetate resin, ethyl cellulose resin, phenol resin, acrylonitrile / vinylidene chloride resin and the like can be mentioned.

In order to form a porous or porous layer made of such an electrostatically chargeable polymer, the electrostatically chargeable polymer is dissolved in a solvent obtained by combining a good solvent and a poor solvent for the polymer. And drying on a support. In this case, the diameter of the pores can be changed by changing the ratio of the good solvent to the poor solvent, and a porous or porous layer can be formed. In the case of a porous material, it is a coarse open hole called a brushing film having a diameter of about 5 μm to 100 μm. This brushing film can be formed by applying a polymer solution and then drying it in a humidity atmosphere of about 60 to 80%. In the case of a porous material, fine open holes having a diameter of about 5 μm or less are used.

Such an electrostatic adsorbent can be used when it is rubbed against various papers, pamphlets, catalogs, booklets, etc.
A large amount of triboelectric charge of 0.9 kV or more or -0.9 kV or less can be obtained, and a document composed of, for example, about four or five sheets of A4 size can be held for a long time only by rubbing with the document.

Pressing member 2 made of a material capable of electrostatic attraction
It is sufficient that at least one end is fixed to the sheet-shaped member 1. The fixing method is a method of bonding with an adhesive, an adhesive, a double-sided tape, or the like, heat fusion, ultrasonic fusion,
