Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a see-through document holder with antistatic ability.

A document holder for storing various documents such as medical records is formed into a bag shape from a see-through plastic sheet-like material such as hard polyvinyl chloride, polyethylene, or polypropylene so that documents can be checked even when they are removed from the holder. , these plastics are hydrophobic and easily chargeable, so during drying when the charging action becomes intense, it is difficult to take out a desired one from a large number of holders lined up using a holder extraction device, and to return the removed holder to its original position. A situation had arisen that made it impossible.

The present invention was developed in view of the above circumstances, and includes at least one side of the front or back cover of a document holder made of plastic made of see-through plastic, and a cover made of see-through plastic. It is characterized by having electrical conductivity so as not to impede transparency.

In other words, in the present invention, at least one side of the front cover and the back cover made of plastic is made of transparent plastic, and almost the entire surface of the cover made of transparent plastic is coated with anti-static material to the extent that it does not impede transparency. The present invention relates to a see-through antistatic document holder in which a conductive material is widely distributed linearly and a front cover and a back cover are integrated.

The document holder of the present invention has electrical conductivity on almost the entire surface of the cover, so it does not charge an electrical charge, and even if it does charge, it is discharged through the human body when the document holder is put in and taken out, so all of the problems mentioned above are solved. It is something that

Note that although the conductive substance is distributed in a linear manner, it is preferably distributed so that the conductive substance intersects with the lines.

The invention will be explained below with reference to illustrated embodiments.

In FIGS. 1 and 2, the document holder A is constructed by integrating a front cover 1 and a back cover 2, each made of a plastic sheet, by welding or the like at the bottom and both sides. It is formed into a bag shape with an opening 3 at the top, and documents 4 such as medical records can be taken in and out of the holder A using the opening 3, and the front cover 1 is made of transparent plastic.

As for the plastic forming each cover 1 and 2, suitable materials such as hard polyvinyl chloride, polyethylene, polypropylene, etc. can be used as in the past, but at least one side of the front cover 1 and the back cover 2 can be seen through. must be formed.

A conductive layer 5 is formed on the outer surface of the front cover 1 by applying conductive paint in a grid pattern.

The conductive paint is obtained by mixing a conductive substance such as carbon black, graphite, or fine metal powder into the resin paint, and in order to apply this conductive paint to the front cover 1, brushing, letterpress printing, letterpress printing, etc. This may be carried out by gravure printing, screen printing, various types of transfer printing, etc.

Further, the conductive layer 5 is not limited to a lattice pattern, but may be formed in a continuous pattern such as a mesh pattern, a zigzag pattern, a concentric circle pattern, a spiral pattern, etc., and it is preferable to form the conductive layer 5 so that the patterns intersect with each other. It may be formed so as to cover the entire outer surface of the.

When serving this conductive paint, as shown in Fig. 3, a thin groove 6 is formed in advance on the front cover 1 with a knife or the like, and the conductive paint is buried in this groove to form a conductive layer. 5
If this is formed, the conductive layer 5 will be difficult to peel off even when it rubs against other holders.

In this way, conductivity is imparted to the front cover 1 by forming the conductive layer 5, but the conductivity 5 may be formed on the inner surface of the front cover 1, and conductivity may also be imparted to the back cover 2 in the same manner. can give.

In order to obtain a large number of such covers 1 and 2, for example, as shown in FIG. 5 are sequentially formed at small intervals in the longitudinal direction of the long sheet material 8,
It is sufficient to cut from this small interval part as shown by the broken line in the figure.

In addition, when the conductive layer 5 is directly formed on one side of the covers 1 and 2, if this is further covered with a thin plastic layer 7 as shown in FIG. 5, the conductive layer 5 may peel off. It becomes difficult.

This thin plastic layer 7 is formed, for example, by laminating plastic sheets or by applying molten plastic.

Here, in order to be able to identify the document 4 housed in the holder A from the outside, one or both of the covers 1 and 2 is made of transparent plastic.A conductive paint is applied to this transparent plastic as shown in FIG. It is best to apply the metal partially, as in the example above, or to evaporate the metal very thinly so that it can be seen through.

At this time, in the case of the former, if the coating rate (area ratio to be coated) is kept at 30% or less, the inside of holder A can be sufficiently penetrated through the parts that are not coated with conductive paint (conductive layer 5). It is something that can be seen.

Note that the holder may be one in which a large number of holders A as shown in Fig. 1 are bound together, and in this case, at least one of the outermost front cover or back cover has a label as described above. It is sufficient to give conductivity by doing so.

As described above, in the present invention, a conductive material is widely distributed on at least one side of the front cover or the back cover to impart conductivity, so there is no charge, or even if it is charged, the charge voltage is low. In addition, when taking documents in and out, humans act as a grounding body and are well discharged, so even when the holder is dry, the holder extraction device can be used to take out a desired holder from a large number of holders lined up, and the removed holder can be used to restore the original holder. It can be returned to the original position completely, and there is no dust attached to it.
