However, in the file of the type described in Patent Document 1, for example, when it is formed as a type that stores A4 size paper, the width dimension is formed with a margin with respect to A4 size paper. For this reason, there is a problem that the stored paper is inclined in the pocket.
In this case, it is possible to prevent the paper from tilting if the pocket width margin is eliminated. However, when such a pocket is set with a width, a curl is attached to the end of the paper near the welded portion. There is an inconvenience. This is because when the paper is stored in each pocket, the back cover side of the front cover and the back cover swells in the thickness direction.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a pocket-type file in which the paper stored in the pocket does not tilt in the pocket. is there.
Another object of the present invention is to provide a pocket-type file that avoids the inconvenience that a part of the cover body swells in a state in which the document is accommodated in each pocket, and can avoid bending of the document. Is to provide.

In order to achieve the above object, the present invention employs a configuration as described in the claims. That is, the present invention is a file comprising a cover body provided with a front cover and a back cover on both left and right sides of the spine cover, and a plurality of transparent pockets welded to the inner surface side of the cover body.
The spine is determined by a pair of left and right fold lines, and has a center fold line between the fold lines,
The front cover and the back cover are provided with a folding line for expanding the binding width parallel to each other at a predetermined interval on the base side thereof,
The pocket is welded to the inner surface on the base side of the front cover and / or back cover via the first welded portion, and the second welded portion narrows the pocket width inside the first welded portion. It has a configuration that comprises.

  In the present invention, it is possible to adopt a configuration in which a slit is provided inside the second welded portion, and the slit forms an opening of the pocket.

  The pocket is provided such that a pocket portion between the first welded portion and the second welded portion acts as a bending allowance.

According to the present invention, by providing the second welded portion, it is possible to form a storage width in which the dimension between the first welded portion and the free end of the pocket is reduced. Therefore, there is no inconvenience that the paper is inclined when a part of the paper stored in the pocket moves to the first welded portion side rather than the second welded portion.
In addition, since the pocket is configured to be welded to the inner surface on the base side of the front cover and / or back cover, it may cause partial swelling of the cover body as seen in the conventional type where welding is performed with the back cover. And there is no curl on the paper in the pocket.
Furthermore, since the pocket portion between the first and second welded portions is easily bent, the pocket portion easily fits between the cover sheets. From this point also, the base side of the front cover and the back cover is Inconveniences such as swelling can be avoided.

  Embodiments of the present invention will be described below with reference to the drawings. Note that terms indicating directions or positions in this specification, that is, “left and right” and “up and down” are used with reference to FIG. 1 unless otherwise specified.

  1 and 2, the pocket-type file 10 includes a back cover 11, a cover body 15 including a front cover 12 and a back cover 13 connected to the left and right sides of the spine cover 11, and an inner surface side of the cover body 15. And a plurality of pockets P made of a transparent resin film.

  The cover body 15 is made of a resin sheet, and the front cover 12 and the back cover 13 are provided so as to be openable and closable with the spine cover 11 side as the open / close center side and the opposite side as the free end. As shown in FIG. 3, the width (left-right width) of the spine cover 11 is determined by a pair of left and right fold lines 20A and 20A. The center fold line 20B is bent at the center position between the fold lines 20A. It is formed in parallel with the line 20A. Further, on the base side of the front cover 12 and the back cover 13, folding lines 20C for expanding the binding width are provided in parallel to each other at a predetermined interval. In the present embodiment, the folding lines 20C for expanding the binding width are not particularly limited, but are formed three by three. Here, each fold line 20A, 20B, 20C includes not only the case where it is formed up to the positions reaching the upper and lower edges of the cover body 15 but also the case where it is a fold line that terminates in front of the upper and lower edges. Note that a transparent film sheet (not shown) can be arranged on the outer surface of the spine cover 11, the front cover 12 and the back cover 13 on the base side to form a heading accommodating portion that opens up and down.

  The pocket P is sized to fit within the front cover 12 and the back cover 13. These pockets P are formed in a bag shape having an opening 22 on the upper end side in FIGS. 1 and 4A, and one end in the width direction is welded to the inner surface of the base side of the front cover 12 and the back cover 13, respectively. One weld portion 25 is provided so as to be integrated with the cover sheet 15. In addition, each pocket P is provided with a second welded portion 26 that narrows the pocket width inside the first welded portion 25. The width W between the second welded portion 26 and the free end of the pocket P is determined in relation to the paper to be stored. For example, when the paper to be stored is A4, B5, or a business card, the width is set so as to allow the paper to be taken in and out and not to cause a substantial inclination in the bag. When the pockets P are overlapped on the front cover 12 side and the back cover 13 side, the number of sheets equal to or smaller than the width of the spine cover 11 is welded. It can be. As shown in FIG. 4 (A), the pocket P in the present embodiment is a bag-like shape in which a single film has a total thickness of two sheets, a second welded portion 26 is provided, and an opening 22 is provided at the upper end. After that, the end portion outside the second welded portion 26 is welded to the front cover 12 and the back cover 13 to form the first welded portion 25 (see FIG. 1) for integration. . Further, as shown in FIG. 4B, the outer film portion from the second welded portion 26 is formed so as to be one sheet thick, and the end portion of the film having the one sheet thickness is welded. The first welded portion may be provided.

  In addition, in this embodiment, the other structure except the structure which provided the said 2nd welding part 26 is substantially the same as Japanese Patent Application No. 2010-107221 for which it applied by the same applicant as this application. It is.

In the above configuration, the file 10 is entirely folded by folding it at the center fold line 20B of the back cover 11 so that the inner surfaces of the front cover 12 and the back cover 13 face each other in a state where no document is stored in each pocket P. To maintain a flat state.
When a document is stored in the pocket P, it can be inserted from the opening between the second welded portion 26 and the free end of the pocket P. When the thickness increases due to document storage, the folding line 20A that determines the width of the spine 11 can be folded and used. When the thickness further increases, the folding line 20C can be folded and used according to the thickness. (See FIG. 5).

Therefore, according to such an embodiment, the second welded portion 26 is provided inside the first welded portion 25, and the width W between the second welded portion 26 and the free end of the pocket P is set as follows. Since the width is slightly larger than the width of the paper to be stored, the inconvenience that the paper stored in the pocket P is inclined can be solved.
Moreover, even if the pocket P between the first welded portion 25 and the second welded portion 26 is bent due to the storage of the document (see FIG. 5), the second welded portion 26 and the pocket P Since the portion between the free ends of the sheet can have a relatively flat shape, it is possible to smoothly put in and out the document.
Further, the space between the first welded portion 25 and the second welded portion 26 (pocket portion) is configured so that the document does not enter, so that the pocket portion is a relatively flexible region. As a result, it acts as a bending allowance and contributes to making the page turning work soft. Further, as shown in FIG. 5, since the pocket portion can be bent freely corresponding to the bending of the back cover 11, the base side of the front cover 12 and the back cover 13 swells relatively greatly with respect to the free end side. To avoid it. Further, as shown in FIG. 5, the second welded portions 26 are arranged in a substantially horizontal row due to the bending of the pocket portion, and the free end side of the pocket P can also be aligned.
Further, as shown in FIG. 5, the pocket P on the side close to the front cover 12 and the back cover 13 bends so that the pocket portion is along the cover body 15. The shape along the line collapses and is greatly bent inward so that it fits comfortably in the space between the cover sheets. From this point also, partial swelling of the cover sheet 15 can be prevented.

As described above, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
That is, although the present invention has been illustrated and described with particular reference to particular embodiments, it is not intended to depart from the technical concept and scope of the invention. Those skilled in the art can make various changes in terms of material, quantity, position or arrangement.
Accordingly, the description of the limitation on the shape and the like already disclosed is an example for facilitating the understanding of the present invention and does not limit the present invention. The description by the name of the member which remove | excluded one part or all part is included in this invention.

For example, in the above-described embodiment, the upper end side of the pocket P is provided with the opening portion 22, but as shown in FIG. 6, the upper end side is sealed and the inner side of the second welded portion 26 is further used. Alternatively, an opening may be formed by forming a slit 27 extending in parallel with the second welded portion 26.
In the above embodiment, the case where the cover body 15 includes the spine cover 11 is illustrated and described. However, the front cover 12 and the back cover 13 can be directly connected without providing the spine cover 11. . Further, although the central fold line 20B is provided in the middle of the spine cover 11 in the width direction, it is not always necessary to provide the central fold line.
Further, the pocket P may be welded to the inner surface of at least one base side of the front cover 12 and the back cover 13 via the first welded portion 25.
