BACKGROUND OF THE INVENTION
The present invention relates to a document holder suitable for storing documents such as brochures and flyers.
[0002]
[Prior art]
Conventionally, a clear holder is known as a document holder that is convenient for organizing and delivering a small amount of documents. Clear holders are used for various purposes in work and daily life because the clear holder sandwiches a document between transparent sheets, making the contents easy to understand. Usually, the sheet piece is formed of a resin material such as polypropylene, and its thickness is about 0.1 to 0.2 mm. The size of the sheet piece is centered on the A4 size, and there are various other sizes such as A3 and B4 depending on the application. As related prior art, the following patent documents 1 to 3 are disclosed.

[Problems to be solved by the invention]
However, since such a conventional clear holder uses a resin material for the sheet piece, a large burden is placed on the environment during manufacture or disposal. In addition, there are abundant variations in colors and sizes, but there are few variations in materials, and there is a problem that the texture cannot be enhanced sufficiently.
The present invention has been made in view of such a situation, and an object thereof is to provide a document holder that improves the texture by using a translucent paper material and is easy to recycle and is environmentally friendly. .
[0005]
[Means for Solving the Problems]
As a result of investigating and researching various paper materials in order to solve the above-mentioned problems, the present inventors have come to focus on the raw material and production method of glassine paper. And the special glassine paper suitable for a document holder was developed, and it came to complete this invention.
That is, the document holder of the present invention (first invention) for solving the above-mentioned problem is a document holder provided with a sheet piece for holding the document in between, and the sheet piece is made of reinforced glassine paper. It is characterized by.
[0006]
According to the document holder of the present invention (first invention), since the sheet piece is formed of reinforced glassine paper, it is excellent in recyclability and hardly burdens the environment. In addition, the original texture of the paper can be given to the surface of the sheet piece, and the texture of the document holder can be enhanced. Further, since the surface of the reinforced glassine paper is translucent, it is excellent in the visibility of the document stored in the holder, and the usability when organizing and storing the document is also improved.
[0007]
In addition, the document holder of the present invention (first invention) can directly print a pattern or a character on a sheet piece with a printer or the like, and has a high design decoration that is difficult with a conventional resin document holder. You can also. It is also possible to hand-write directly with a water-based pen or pencil, or directly press a seal.
Furthermore, since the document holder of the present invention (the first invention) is made of paper, it can be easily folded and expanded, and can be easily processed such as binding holes (punch holes) and gluing.
[0008]
In general, glassine paper is a thin paper in which transparency is increased by subjecting paper made by highly beating chemical pulp to a paper and compressing it with a super calendar. The surface of glassine paper has properties such as micron-sized pores that have low air permeability and excellent oil resistance, such as food and magazine packaging, drug packaging, laminated paper, container lining, and transparent envelope windows Is used.
The “reinforced glassine paper” referred to in the present invention (first invention) means a glassine paper in which the thickness of the paper surface of the glassine paper is formed to be several times to several tens of times the normal, and the strength of the paper surface is increased. Since there are few voids between cellulose fibers as in general glassine paper, the transparency of the paper surface is increased. In the present invention (first invention), by using reinforced glassine paper as a sheet material, it is possible to realize a document holder having an appropriate transparency and strength even when made of paper.
[0009]
Tracing paper is known as a paper having a translucent paper surface. This type of paper beats the raw pulp “extremely” and eliminates bonds between fibers to increase transparency. However, since the beating process is complicated and time-consuming, the manufacturing cost is high and it is not suitable for mass production. Since the present invention uses reinforced glassine paper that can be manufactured at a low cost with a relatively simple manufacturing process, it can easily cope with mass production of document holders.
[0010]
In the present invention (first invention), as the raw material pulp of the reinforced glassine paper, softwood bleached sulfite pulp (NBSP), softwood bleached kraft pulp (NBKP), hardwood bleached kraft pulp (LBKP) and the like can be used. In order to increase transparency, softwood bleached sulfite pulp may be used, and softwood bleached kraft pulp may be used from the viewpoint of production cost. In addition, you may mix | blend a chemi-ground pulp, a semi-chemical pulp, a mechanical pulp, a used paper pulp, a synthetic pulp etc. with these chemical pulp suitably. Further, raw material pulp other than wood (bamboo pulp, bagasse (sugar cane residue) pulp, hemp pulp, straw pulp, etc.) may be used.
As for the beating degree of the pulp, moderate oil resistance and transparency can be obtained when beating to about 100 to 400 ml with Canadian Standard Freeness (CFS).
[0011]
Various chemicals can be added to the raw material pulp as long as the transparency of the paper surface is not impaired. Examples of the additive include a sizing agent, a paper strength enhancer, a filtering agent, a dye, a yield improver, a slime control agent (for sterilizing microorganisms), an antifoaming agent, an antistatic agent, and the like.
[0012]
In the present invention (first invention), various calendars such as a gloss calendar, a soft compact calendar, etc. can be used in addition to the super calendar for the compression process on the paper surface. The calendar may be either on-machine or off-machine.
The thickness of the reinforced glassine paper is about 100 to 200 μm (80 to 120 g / m ² ), preferably about 120 μm. This is because if the thickness is too small, the strength of the paper surface tends to decrease, and if the thickness is too large, the transparency of the paper surface becomes poor.
[0013]
The document holder of the present invention (second invention) is characterized in that transparent ink is applied to the surface of reinforced glassine paper.
In the present invention (second invention), by impregnating the surface of the reinforced glassine paper with a transparent ink, it becomes possible to reduce the gaps between the cellulose fibers, suppress the scattering of light, and further increase the transparency of the paper surface. . Thereby, it becomes easy to manufacture a durable and durable document holder.
In addition, according to the present invention (second invention), the transparent ink is attached to the reinforced glassine paper, so that the elasticity of the paper surface is increased and the sheet piece of the document holder can have an appropriate “crisp” feeling.
[0014]
Here, as a material that can be used as “transparent ink”, for example, urethane-based or cellulose-based synthetic resin (clearing varnish), pine resin, amino resin, wax, and other various chemicals for transparency may be used. In particular, when a transparent ink with good heat resistance is used, the print quality of the paper surface can be improved.
[0015]
The document holder of the present invention (third invention) is characterized in that the surface of the reinforced glassine paper is embossed.
According to this invention (3rd invention), since the unevenness | corrugation by embossing is given to the surface of a sheet piece, it is hard to adhere | attach a document between sheet pieces. In addition, since the contact area between the sheet piece and the document is reduced, generation of static electricity due to rubbing of the paper surface can be suppressed. Furthermore, the transparency of the paper surface is improved by applying pressure to the paper surface by embossing. As a result, it is easy to handle the document when it is taken in and out, the texture and feel of the sheet surface are improved, and the sense of quality of the document holder is increased.
[0016]
It should be noted that the embossing is preferably performed by compressing the paper surface with a dedicated roller with unevenness when manufacturing reinforced glassine paper. Various patterns and patterns can be applied to the paper according to the uneven shape of the embossed plate. The embossed plate can effectively increase the paper strength by selecting a pattern having a relatively large number of convex surfaces.
[0017]
The present invention (first to third inventions) may be applied alone as necessary, or may be applied in combination with each other. Further, other inventions described in this specification may be combined.
The document holder according to the present invention (first to third inventions) is used for organizing, delivering, and storing various documents such as brochures, flyers, catalogs, reports, estimates, proposals, novelty documents, medical charts, and the like. And convenient.
