Description

[0001]
BACKGROUND OF THE INVENTION
This invention can be used to store paper holders that are suitable for use by elementary school students, such as photo shoots, plant observations, and social studies tours. More specifically, regarding the bag-like container used to do this, it is in a thin form when not in use, but when used, a bag part structure that can hold a thick article and this bag part are used. It relates to goods.
[0002]
[Prior art]
Examples of the paper sheet holder in the above example include those described in registered utility model table 3025155. This paper sheet holder has a structure having a clip that is attracted to the plate part by a magnet when folded back at the upper edge of the rectangular plate-like plate part, and a bag-like case on the opposite surface. .
[0003]
With such a paper sheet Hoda, it is very convenient because you can write letters and pictures if you pinch the paper, and you can put notes, pencils, collected items, etc. in the back case. .
[0004]
However, the case is formed by attaching a thin synthetic resin sheet by heat welding (welder), and is three-dimensionally formed so that an article having a certain thickness such as a pencil or a loupe can be inserted. For this reason, there is a thickness even when nothing is put in, and it takes up space in the management as a product, and it becomes an obstacle when not in use. In addition, since a case formed in a three-dimensional shape is attached, there is a problem that it takes time and money for processing.
[0005]
[Problems to be solved and means for achieving them]
In view of the above, the main object of the present invention is to allow a thick article to be put in the formation of the bag portion and to save the usual space, so that the manufacturing cost is not reduced.
[0006]
Means therefor is a thin bag portion formed of a sheet-like body, and on the bag surface of the bag portion, a plurality of linear folding overlapping portions that are folded inward and superposed in three layers are formed, forming a cross-section of these folding polymerization unit intersect, characterized in that the outer peripheral edge portion of the bag surface, a thickness out structure of the thin bag portion fixing the polymerized state of the folding polymerization unit.
[0007]
That is, in the formation of the bag portion, the sheet-like body forming the bag surface on the side that enables the thicknessing is folded so that a plurality of folded overlapping portions and crossing portions are formed, and in this state, For example, what is necessary is just to attach to a predetermined position by appropriate means, such as heat welding, sewing, and adhesion | attachment.
[0008]
In addition, when forming the plurality of folding polymerization portions, it may be arranged so that a bag mouth for putting in and out the article can be formed at one end, and a portion surrounded by the plurality of folding polymerization portions is formed, A bag mouth may be formed.
[0009]
Since it folds so that a folding superposition part may be made, the form of a bag part is flat. In use, if an article or the like is put in the bag part, the polymerization of the folded polymerization part is released, and a thick article can be stored, and the polymerization is also removed at the intersection where the folded polymerization parts cross each other. Can be taken out.
[0010]
The sheet-like body may be formed in a square shape, and the plurality of folded overlapping portions may be formed vertically and horizontally along the side of the sheet-like body . In this case, if it is formed in a straight line with the same width, bending is easy. The formation of the folded overlap portion can be easily performed according to the shape of the bag portion, and because of the presence of the folded overlap portion, sufficient thickness can be obtained even when the bag mouth is closed and the thickness can be adjusted to a stable form. This is because it can be done.
[0011]
Further, a plurality of the folded overlapping portions may be formed in the same direction. Even if the width of the folded overlap portion is narrow, the thickness can be increased.
[0012]
Further, the plurality of folded overlapping portions may be formed in, for example, an elongated triangular shape with emphasis on the design feeling, or a plurality of such folded overlapping portions may be stacked.
[0013]
Another means is a paper sheet holder having a clamping means for clamping the paper sheet at at least one side edge of the hard plate part, wherein the thickness of the thin bag part is at least on one side of the plate part. It is a paper sheet holder in which a bag portion having a take-out structure is formed.
[0014]
The formation of the bag portion is simple and the cost can be reduced because the outer peripheral edge only needs to be welded to one surface of the plate portion after the sheet-like body is bent. Moreover, since the bag portion is flat when attached to the plate portion, the bag portion need not be bulky when the article is not inserted.
[0015]
Still another means is a bag-like container formed of a sheet-like body, wherein the bag surface of the bag-like container is a bag-like container using the thinned-out structure of the thin bag portion. .
[0016]
The bag-shaped container is formed by using, for example, a sheet-shaped body having a size that forms both surfaces of the bag-shaped container, forming a plurality of folded overlapping portions in the sheet-shaped body, and folding the sheet-shaped container in half. What is necessary is just to join corresponding parts, leaving a bag mouth. Since it is only necessary to fold and join, processing is easy and cost can be reduced. Moreover, since the bag-like container has a flat shape in which sheet-like bodies are stacked, it is compact and does not take up space and is easy to handle.
