Abstract

The folding part 22 for installing a binding member 12 is provided to an inner surface side of a cover body 11. The folding part is composed of a pair of folding part forming pieces 22A, 22B wherein a part of paper-made sheet S is superimposed in two sheets thickness, and a protrusion 30 formed by press impression is formed inside a surface of the folding part forming piece 22A of one side. When the folding parts are bonded to each other by applying water soluble adhesive A to joint surfaces of the folding part made piece, an adhesion state is stably maintained by the protrusion 30.

Description

[0001] technology area [0002] The present invention relates to file folders, in particular to file files that can be recycled without impurities. Background technique [0003] As shown in FIG. 5 , there is known a folder (beaded folder) 57 in which a part of the thin plate S constituting the sandwich body 50 is overlapped in two layers on the inner surface side of the sandwich body 50 to form a folding portion. 52 , a binding clip 56 composed of a binding foot 53 and a binding plate member 54 is detachably provided in the region of the folded-in portion 52 . [0004] However, such a folder 57 maintains its double-layer thickness by binding the staples 58 of a stapler in the planes of a pair of fold-in portion forming pieces 52A formed by overlapping each other so as to form the fold-in portion 52 . Structure. [0005] Therefore, in the case of incinerating the folder 57 for disposal, the staple 58 of the stapler cannot be incinerated. In addition, when it is desired to reg...

Problems solved by technology

[0008] However, in the folder manufacturing method disclosed in Patent Document 1, especially when the fold-in portion forming sheets are bonded to each other with a water-soluble adhesive such as starch paste, since the thin plate constituting the folder body is made of hard Since it is made of high-quality paper, the tendency to return to the original flat position after folding has a strong effect. Therefore, there is a possibility that the folding-in forming pieces will separate from each other and stick to each other at the stage before the binder is installed after bonding. The reception will be lifted such a bad situation

Therefore, in order to stably maintain the bonded state, it is necessary to continuously apply a pressing force to maintain the mutual adhesive force from the outside to the tuck-in portion forming sheet, which becomes a major factor that complicates the manufacturing process.

[0009] Although it is considered that the above-mentioned release of bonding can be eliminated by using a so-called solvent-based adhesive of the type called an instant adhesive, in this case, there is not only an increase in material cost , and there is also a bad situation that the operating environment is significantly lower due to the vaporized gas filling the surrounding area

[0010] In addition, as a particularly problematic matter, when the folder is reused as recycled paper, the composition of the adhesive remains in a hardened state without being dissolved, and this becomes impurities, which leads to failure to obtain ideal recycling. Bad condition like paper
