Description

  The present invention relates to a file, and more particularly to a pocket type file in which a plurality of pockets formed of a transparent resin sheet are welded to a cover sheet.

A pocket-type file consists of a front cover, a cover body consisting of a back cover connected to the front cover via a back cover, and a resin film (pocket) that is open on one end and welded to the inner surface side of the cover body. It is configured.
A known pocket file is disclosed in, for example, Patent Document 1. When the file disclosed in the document is outlined, as shown in FIGS. 11 to 13, as shown in FIGS. 11 to 13, a cover body 55 in which a spine cover 52 is connected to a cover cover 50 via a spine cover 51, and an inner surface side of the cover body 55 And a plurality of pockets 56 provided in the. The pockets 56 are integrated with the cover body 50 by providing a welded portion 57 on the back cover 52 at the center thereof.
According to such a file, in the state where a large number of open-end pockets 56 each having a size straddling the front cover 50 and the back cover 52 are overlapped, the central portion thereof is welded to the spine cover 52 to be welded 57. Therefore, pockets 56 can be formed on the inner surfaces of the front cover 50 and the back cover 52, respectively.

Japanese Utility Model Publication No. 55-99880

  However, in the file described in Patent Document 1, since the central portion of the pocket 56 having a size straddling the front cover 50 and the back cover 52 is welded to the spine cover 52, as shown in FIG. The width of the spine cover 51 cannot be narrowed even if no document is accommodated in the pocket 56 due to the necessity of providing a welded portion. Therefore, a spine with a certain width is essential, and accordingly, the volume when packing a large number of files becomes bulky. That is, the file described in Patent Document 1 cannot be applied to a thin type cover body having no spine.

  Further, in the state where the documents are accommodated in the respective pockets 56, as shown in FIG. 14, the base side which is the open / close center side of the front cover 50 and the back cover 52 swells relative to the free end side and becomes relatively thick. The tendency to increase becomes strong, the file cannot be stacked, and the handling property when carrying it becomes worse. Moreover, in such a case, the upper end side (free end side) of each pocket in FIG. 14 becomes uneven, and the appearance looks worse. Furthermore, since it is inevitable that the pocket 56 bends on the welded portion 57 side, there is a disadvantage that the document in the pocket 56 is bent and wrinkled.

  By the way, when the pockets are welded to the inner surface of the cover body, if the number is too large, welding becomes difficult. Therefore, in a conventional type file in which pockets are formed by welding at one place, the number of pockets is limited to a range where welding is possible, and a larger number of pockets cannot be secured.

[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 that can be thinned even when a large number of pockets are welded. It is in.
Another object of the present invention is to provide a file capable of increasing the number of pockets by performing welding for each unit with a plurality of pockets as one unit.
Furthermore, an object of the present invention is to avoid the inconvenience that a part of the cover body swells in a state in which the document is accommodated in each pocket, to avoid the curl of the document and to make the free end side of each pocket uneven. It is an object of the present invention to provide a pocket-type file that can improve the conventional inconvenience.

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 including a cover body provided with a front cover and a back cover, and a pocket welded to the inner surface side of the cover body,
The cover body includes a spine, and the front cover and the back cover are connected to both sides of the spine in the width direction via folding lines,
A folding line for binding width expansion is provided on the base side of the front cover and the back cover,
The pocket is configured to be welded to the inner surfaces of the front cover and the back cover on the base side.

  In the present invention, the pocket may be welded by shifting the position in the width direction on the inner surface of the base side of at least one of the front cover and the back cover, with a plurality of pockets as a unit.

  Further, the pockets to be welded to the front cover and the back cover, respectively, are configured such that when they are overlapped, a number equal to or smaller than the width of the spine is welded.

  Further, a configuration is adopted in which a center fold line is provided in the middle of the spine cover in the width direction.

  According to the present invention, since the pocket is welded to the inner surface of the base side that is the opening / closing center side of the front cover and the back cover, a file with a narrow back cover can be formed.

  Further, according to the configuration in which the folding line for expanding the binding width is provided, the necessary folding line is bent according to the thickness change when the document is stored in the pocket. Therefore, the entire file has a substantially uniform thickness in a flat state, the degree of unevenness on the free end side of the pocket can be greatly improved, and stable accommodation in a cabinet or the like can be realized.

  Note that a plurality of pockets as a unit can be welded in a state where the pockets are displaced in the width direction on the inner surface on the base side. In this case, the number of pockets is within a range where welding is possible. Even if there are restrictions, it is possible to provide a file that can increase the number of pockets.

Furthermore, when the number of pockets in which the thickness when the pockets welded to the front cover and the back cover are overlapped is smaller than the width dimension on the spine cover, at least the width of the spine cover is at least unused. For example, when shipping from a factory to an agent or the like, the packaging can be performed without creating a useless space.
At this time, by providing a center fold line in the middle of the spine in the width direction, the cover body can be folded in two along the fold line, the initial thickness is minimized, that is, the thickness of the front cover and the back cover, and each The thickness can correspond to the total thickness of the pockets between the covers.

(First embodiment)
Embodiments of the present invention will be described below with reference to the drawings. In this specification, unless otherwise specified, the short width direction of the spine shown in FIG. 2 is the left and right, and the long direction is “up and down”.

  In FIG. 1 and FIG. 2 showing the first embodiment, a 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, A plurality of pockets P made of a transparent resin film provided on the inner surface side of the cover body 15 are provided.

  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. 4, the width (left-right width) of the spine cover 11 is determined by a pair of left and right fold lines 20A, 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, three folding lines 20C for expanding the binding width are formed. 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. A transparent film sheet 30 is disposed on the outer surface of the spine cover 11, the outer surface of the base cover 12 and the back cover 13, and the left and right sides are welded to the outer surfaces of the front cover 12 and the back cover 13 to cover the front cover. 12, a base side outer surface of the back cover 13 and an outer surface of the spine cover 11 and the film sheet 30 are formed as 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 that opens the upper end side in FIG. 2, and one end side in the width direction is welded to the inner surface of the base side of the front cover 12 and the back cover 13 so as to be integrated with the cover body. It has become. When the pockets P on the front cover 12 side and the back cover 13 side are overlapped, the number of sheets equal to or smaller than the width of the spine cover 11 is welded to each other. It can be a thickness. Although not particularly limited, the file 10 according to the present embodiment is suitable for accommodating A4 size documents in the pocket P. The width dimension of a general pocket for accommodating A4 size documents is about 223 mm, but the pocket of this embodiment is set to be about 5 mm larger than that.

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.
On the other hand, when a document is stored in the pocket P, the folding line 20A that determines the width of the spine cover 11 can be folded and used. When the thickness further increases, the folding line 20C is folded and used according to the thickness. (See FIG. 5).

Therefore, according to the first embodiment, since the pocket P is welded to the inner surfaces of the front cover 12 and the back cover 13 on the base side, the vicinity of the welded portion of the pocket P is deformed into a wave shape. This makes it difficult to avoid the inconvenience that the base portions of the front cover 12 and the back cover 13 swell relative to the free end side. Further, as described above, by providing the pocket P with a large width, the pocket edge on the welded portion 25 side is bent and displayed even in a state where the document is accommodated only in each pocket P on the cover 12 side. There is no inconvenience that the base side of the cover 12 swells.
Further, the free end side of each pocket P is also maintained in a state where the free end sides of the pockets P are aligned with respect to the conventional example in which the center portion protrudes outward in a side view.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

The file 10 according to the second embodiment is characterized in that a plurality of pockets P are used as a unit and are welded while being shifted in the width direction on the inner surfaces of the base side of the front cover 12 and the back cover 13. Specifically, the pocket P shown in the first embodiment and a position shifted in the width direction from the position of the welded portion 25 of the pocket P, that is, the free end side of the cover body 15 with respect to the welded portion 25. The welded portion 25A of the pocket P is provided at a position shifted to the position and is added. Here, the unit of the pocket P depends on the thickness of the film used as the material of the pocket. For example, 10 or 20 sheets that can be welded can be exemplified. Twenty pockets P are arranged on the inner surface sides of the back cover 13 and the back cover 13, and 40 pockets P are formed as a whole.
In addition, although the welding part 25 has shown the state formed in dot shape along the up-down direction of the cover body 15, you may provide continuously similarly to 1st Embodiment, and also of 1st Embodiment The welding part 25 can also be provided similarly to 2nd Embodiment. Further, in the illustrated example, the heading accommodating portion by the film sheet is omitted on the outer surface side of the cover body 15, but the heading accommodating portion can be formed as in the first embodiment.

  According to such an embodiment, as shown in FIG. 10, the same effect as that obtained in the first embodiment can be obtained, and the number of the pockets is increased as compared with the pocket P of the first embodiment. The file 10 can also suppress a local increase in thickness when the cover 15 is closed,

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 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 may 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. Furthermore, in the second embodiment, the inner surfaces of the front cover 12 and the back cover 13 are welded while shifting the position in the width direction with a plurality of sheets as a unit, but in the width direction on the base side inner surface of at least one cover. It may be welded by shifting the position.

  Further, the pocket P is not limited to the case of welding a bag-like material having an open upper end, but a two-edge open type with the upper end and one end edge connected to the upper end being used as a material. By welding to the cover body side, it is possible to form a pocket that only the upper end is opened. Further, the pocket P may be formed in a bag shape opened to the back cover side without opening the upper end so that documents can be taken in and out from the lateral direction.
