This paper sheet holder has a structure in which a clip which is folded back and is attracted to the plate portion by a magnet is provided on an upper edge of the rectangular plate portion, and a bag-shaped case is provided on the opposite surface. .

[0003] In such a paper sheet holder, if a paper sheet is sandwiched and stopped, characters and pictures can be written, and a notebook, a pencil, a collection item, and the like can be put in a case on the back side. It is convenient.

[0004] However, the above-mentioned case is formed by attaching a thin synthetic resin sheet by heat welding (welder), and is formed three-dimensionally so that an article having a certain thickness such as a pencil or a loupe can be put therein. . For this reason, there is a thickness even when nothing is put in, and it takes up space in management as a product, and becomes an obstacle when not in use. In addition, since a case formed in a three-dimensional shape is attached, there is also a disadvantage that processing is troublesome and costly.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bag that can be used to store thick articles and to take up a small amount of space, so that the manufacturing cost and effort are reduced. Is the main issue.

In addition, it is characterized in that it has a thickness increasing structure of a thin bag portion in which these folded portions are crossed to form a crossing portion.

That is, when forming the bag portion, the sheet-like body forming the bag surface on the side where the thickness can be increased is folded so as to form an intersection with a plurality of folding overlapping portions. As it is, it may be attached to a predetermined position by an appropriate means such as heat welding, sewing, bonding or the like.

[0008] When forming the plurality of folded portions, the bag openings for taking in and out the articles may be arranged at one end, and a portion surrounded by the plurality of folded portions may be formed. A bag mouth may be formed in the portion.

The shape of the bag portion is flat because it is folded so as to form a folded portion. In use, if an article or the like is put in the bag portion, the polymerization of the folding overlap portion is released, and a thick article can be stored, and the polymerization is released at the intersection where the folding overlap portion intersects, further increasing the thickness. Can be delivered.

[0010] It is preferable that the plurality of folded portions are formed vertically and horizontally. In this case, bending is simple if they are formed in a straight line with the same width. The formation of the fold overlap section can be easily performed according to the shape of the bag section, and the presence of the fold overlap section extending laterally allows sufficient thickness to be obtained even when the bag mouth is closed, and provides a stable form of thickness. Because it can be done.

[0011] Further, a plurality of the folding overlapping portions may be formed by overlapping in the same direction. Even if the width of the folded back portion is small, the thickness can be increased.

Further, the plurality of fold overlap portions may be formed, for example, in an elongated triangular shape, or a plurality of such fold overlap portions may be formed with emphasis on design feeling.

Another means is a paper sheet holder having a holding means for holding paper sheets at least at one side edge of a hard plate portion, wherein the thin bag is provided on at least one surface of the plate portion. It is characterized in that it is a paper sheet holder in which a bag portion having a thickness increasing structure is formed.

The formation of the bag portion requires only bending the sheet-like body and then welding the outer peripheral edge thereof to one side of the plate portion, so that the cost can be reduced simply. In addition, since the bag portion has a flat shape attached to the plate portion, it does not need to be bulky when no articles are put.

Still another means is a bag-like container formed of a sheet-like body, wherein the bag-like container has a thin-walled portion formed on the bag surface thereof. Features.

The bag-like container is formed, for example, by using a sheet-like body having a size to form both sides of the bag-like container, forming a plurality of folded portions on the sheet-like body, and folding it in half. The corresponding portions may be joined by bending, leaving the bag mouth. Since it is only necessary to fold and join, the processing is simple and the cost can be reduced. Further, since the bag-like container has a flat shape in which sheet-like bodies are stacked, it is compact, takes up little space, and is easy to handle.
