SOLUTION: The clear file 10 is formed by folding a rectangular mount 101 in half along a valley fold line 105 and adhering the lower sides of opposite surfaces on the back side of the fold, and the mount is a translucent paper. It is made of a material, and in the mount, the back side of the two folds is waterproof except for the adhesive area 103 on the lower side, and the front side of the two folds is completely waterproof, and further, the front side of the two folds. The surface is coated with an anchor that improves toner adhesion. [Selection diagram] Fig. 1

Description

The present invention relates to a clear file, which is a holder for pointing a document.

Recently, in the movement of SDGs (Sustainable Development Goals), companies, government agencies, and the private sector are required to take concrete actions toward deplasticization.

It can be said that clear files, which are often used for document management, are also one of the targets of deplasticization.

As a material other than plastic, for example, a paper clear file is generally inferior to a PP (polypropylene) clear file in terms of transparency, strength, and the like.

On the other hand, when tracing paper, which is a translucent paper material, is used in consideration of transparency, the tracing paper easily absorbs moisture. The surface that has absorbed moisture expands, curls up, and is deformed. Such deformation makes it difficult to maintain the shape required to store and hold the document in the file, causes damage, and has problems in terms of strength and durability.

Therefore, it is an object of the present invention to provide a semi-transparent clear file of a paper material, which is suitable for printing on the front side and can avoid deformation due to moisture or the like.

According to the present invention, it is a clear file formed by folding a rectangular mount in half and adhering the lower sides of the opposite surfaces on the back side of the two folds, and the mount is made of a translucent paper material. In the mount, the surface of the back side of the bi-fold is waterproof except for the adhesive region on the lower side, the front surface of the bi-fold is completely waterproof, and the front surface of the bi-fold is further waterproofed. The surface is provided with a clear file coated with an anchor that improves toner adhesion.

According to the present invention, it is possible to provide a semi-transparent clear file of a paper material which is suitable for printing on the front side and can avoid deformation due to moisture or the like.

(A) and (B) are a plan view and a sectional view illustrating an embodiment of the present invention. It is a top view explaining the modification of embodiment of this invention. It is a side view of the modification of embodiment of this invention.

FIG. 1A is a diagram illustrating a configuration of an embodiment of the present invention. FIG. 1A is a schematic plan view of an unfolded clear file 10. FIG. 1B is a diagram schematically showing a cross section of line AA of FIG. 1A. As shown in FIG. 1B, the mount 101 of the clear file 10 according to the embodiment of the present invention is made of tracing paper 101a, which is a translucent paper material. Tracing paper is a paper (glassine paper) that is made translucent by beating pulp as a raw material and compressing it through a roll, or by using chemicals or the like to reduce air gaps in the paper.

Adhesive portion 103 on the lower side of the front surface of the rectangular tracing paper 101a (the surface that becomes the outer side when folded in half along the valley fold line 105) and the back surface (the surface that becomes the inner side when folded in half along the valley fold line 105). The area other than the above is coated with a waterproof material 101b such as a water-based preventive varnish. The waterproof material 101b is not applied to the adhesive portion 103 in order to ensure adhesiveness.

Further, the surface that becomes the front side (outside) when folded in half along the valley fold line 105 is coated with the anchor resin 101c. The anchor resin 101c imparts heat resistance and water resistance to the tracing paper 101a for printing on the laser printer, and improves the adhesiveness of the toner of the laser printer.

The semi-circular cutout shown in 102 is a thimble. The rounded corner portion (corner R processed portion) 104 is provided on the upper side corner portion on the opposite side of the double-folded valley fold line 105, but may be further provided on the upper side valley fold line 105 side.

The adhesive portion 103 is a region for adhering the facing portions on the inner (back side) when the mount 101 is folded in half along the valley fold line 105. In this example, the adhesive portion 103 extends from the left end to the right end of the mount 101. ing. An adhesive (glue) is applied to the adhesive portion 103 of the mount 101 in the manufacturing process (for example, silk screen printing), and the mount 101 is cut from the roll paper and folded in half. The adhesive portions 103 (opposite surfaces inside the two folds) are adhered to each other and fixed in the two fold state.

FIG. 2 is a plan view showing a modified example of FIG. 1 (A). Similar to a commercially available PP (polypropylene) clear file, a triangular notch 106 is provided at the lower part of the side surface of the mount 101 where the finger rest 102 is located. The notch 106 is for preventing the force applied when the file is opened from being concentrated on the adhesive portion 103 and peeling off the adhesive, and for improving the durability. The adhesive portion 103 does not reach the valley fold line 105 from the left end and the right end of the lower side of the mount 101, respectively, but extends to the front of the valley fold line 105.

FIG. 3 is a side view showing a state in which the valley fold line 105 of FIG. 2 is folded in half and the adhesive portion 103 on the lower side is adhered. Note that the clear file 10 of FIG. 1A is the same as that of FIG. 3 except that there is no notch 106.

In addition to the effect of reducing the amount of moisture absorbed by waterproofing, the clear file 10 has improved water resistance by being fully waterproofed on both sides, and has become harder and harder to curl, increasing its strength as a clear file. Increases durability to maintain shape.

In addition, although tracing paper is usually considered to have a rough texture on the back surface, according to the present invention, the back surface (inner surface when folded in half along the valley fold line 105) is also formed by waterproofing both sides. The texture is as smooth as the surface, making it easier to handle documents in and out of the clear file 10.

By anchor-cotting the printed surface of the mount 101, for example, when arbitrary information (color image, information) is printed by a user with a laser printer or the like, the color fixing property is improved and the printing durability is improved. ..
