Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf holder, and more particularly to a portable leaf holder having a pocket that can store unused loose leaves and used loose leaves separately and store them in a single holder. .

[0002]

2. Description of the Related Art A loose leaf has been known which is intended to easily add and remove a binder in order to eliminate the inconvenience of carrying a binder.
The packaging form of the loose leaf at the time of sale is usually stored in a transparent film bag every predetermined number of sheets. Therefore, when carrying, it is carried out in a state of being stored in a bag and taken out one by one when necessary for writing. However, such a method of use has a disadvantage that the packaging bag itself is easily damaged, and in particular, the damage around the opening causes the loose leaf, which is a storage object, to be bent or bent.

Therefore, recently, leaf holders as shown in FIG. 5 have come into circulation. The known leaf holder 50 includes a pair of covers 51 and 52 and a pocket forming piece 5 provided on the inner surface side of the covers 51 and 52.
4, 55, and lid pieces 56, 57 that overlap with the upper edge side of each pocket forming piece 54, 55. A center portion of the leaf holder 50 in the left-right direction is formed as a bent portion 58, and the pocket forming pieces 54 and 55 are foldable at the bent portion 58 so as to overlap each other.

The pocket forming pieces 54 and 55 are formed as sheets extending on the same plane from the lower edges of the covers 51 and 52 in the state before molding, and the portions corresponding to the lower edges of the covers 51 and 52 are formed. While folding inward, each cover 51,
It is formed as a two-piece open type pocket by thermocompression bonding to the free end side of 52. On the other hand, the lid piece 5
Sheets 6 and 57, which are formed as separate bodies, are prepared in advance, and they can be polymerized on the upper portions of the pocket forming pieces 54 and 55 by thermocompression bonding to the upper edges of the covers 51 and 52.

[0005]

However, in such a leaf holder 50, the left and right pocket forming pieces 54, 55 are simply superposed on the inner surfaces of the covers 51, 52. Therefore, covers 51 and 5
2 and pocket forming pieces 5 corresponding to these covers
The gaps formed between 4, 55 are extremely small, and there is the inconvenience that a large number of unused loose leaves cannot be stored and carried. Moreover, since the leaf holder 50 has a bilaterally symmetrical structure, no consideration has been given to separately storing unused loose leaves and used loose leaves.

Further, the pocket forming pieces 54 and 55 of the leaf holder 50 are opened in a direction such that the leaf insertion port, that is, the upper portion on the side of the bent portion 50 is peeled from the inner surface of the cover sheets 51 and 52, so that the lid piece 56 is formed. , 57 are raised and the closed state is released by this, but as shown in FIG. 5, only the inclined edges 56A, 57A are provided at one end of the lid pieces 56, 57, and It is a structure in which the overlapped area in the direction hardly changes. Therefore, when trying to open the pocket forming pieces 54, 55 largely, the frictional resistance generated between the outer surface of the pocket forming pieces 54, 55 and the inner surfaces of the lid pieces 56, 57 also becomes large, and the leaf holder 50 must be formed of a soft material. There is also the inconvenience that the usable resin material is limited, such as not being possible.

[0007]

SUMMARY OF THE INVENTION The present invention was devised by focusing on the inconvenience of the conventional example, and an object thereof is to store unused loose leaves and the like in a lump.
It is an object of the present invention to provide a leaf holder that can store used loose leaves at different positions within a single holder, and can also provide durability while achieving smooth storage.

[0008]

In order to achieve the above object, the present invention is a leaf holder provided with a pair of left and right cover sheets and pockets formed inside the cover sheets, one pocket being the other. The structure is set to be larger than the storage thickness width of the pocket.

Further, according to the present invention, in a leaf holder provided with a pair of left and right cover sheets and pockets formed inside the cover sheets, one pocket is folded back inward from the cover sheet and upper and lower edges of the cover sheet. It is also possible to employ a configuration in which a gusseted portion and a pocket forming piece extending from the free end of the cover sheet toward the base end are provided, and upper and lower edges of the pocket forming piece are connected to the gusset portion. The storage thickness can be ensured with a relatively simple structure.

Further, according to the present invention, in a leaf holder provided with a pair of left and right covers and pockets formed inside the covers, one pocket is formed as an open-ended type having a gusset portion. The other pocket is provided with a lower edge side of the cover sheet, a two-edge open type pocket forming piece having a closed structure on the free end side of the cover sheet, and a lid piece which is superposed on the upper portion of the pocket forming piece, and the pocket forming piece. A configuration is adopted in which the overlapping area with the lid piece is set to be gradually smaller from the leaf insertion port in the insertion direction. With this configuration, when opening the pocket forming piece in a direction such as peeling it from the cover, the resistance for opening the pocket forming piece becomes gradually smaller, which allows a smooth opening operation, and the entire leaf holder has a certain hardness. It has the advantage that it can be molded with a material having a certain thickness.

In the leaf holder, it is preferable that a tongue piece extending from the free end side of one cover to the base end side of the cover is provided. By providing so that it can be locked on the side,
Prevent the bound cover from opening accidentally.

Further, it is preferable to form folds on each of the front and back surfaces of the gusset portion, on the base portion side of the pocket forming piece and on the free end side of the cover sheet opposed thereto. By configuring this fold line, the gap between the pockets can be increased without difficulty in accordance with the storage thickness.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the leaf mainly includes loose leaves, and also includes various kinds of sheet type sheets, such as report sheets and photographs. As the molding material of the leaf holder, various resin materials such as vinyl chloride resin and polypropylene can be used. The hardness of the molded product may be, for example, the hardness found in a laminated tube or a hardness somewhat harder than that. In short, it suffices that the pocket-forming piece used for the two-edge open type pocket has such a flexibility that it can be opened while releasing the polymerization with the lid piece. As the molding material, hard paper or the like can be used as needed, in addition to the resin material.

When molding the leaf holder, it is possible to mold a single resin sheet material into a predetermined shape by pressing or the like, and bend it. The cover and the pocket forming piece that is folded to the inner surface side of the cover are mainly connected by thermocompression bonding or welding, but adhesive bonding or the like can also be adopted, and metal fittings for reinforcement and the like are also used as needed. be able to.

The entire leaf holder includes both a transparent type and an opaque type, and appropriate printing or labeling can be performed on the cover surface. Further, by providing a plurality of types of leaf holders of various sizes with different plane areas of the pockets according to the paper size of the storage object, it is possible to meet the needs of the user.
