First Embodiment
FIG. 1 is a perspective view of a file according to the present embodiment, and FIG. 2 is a perspective view of the file in a folded state.

  As shown in FIG. 1, in the file 10, one substantially rectangular sheet body 11 is folded at the bottom side 12 and overlapped, and one side of two superposed sheet bodies 11 is welded. The welded portion 13 (first side) is formed. The upper side and the other side (second side) of the file 10 are released, and a document or a piece of paper can be inserted from there and sandwiched. The sheet 11 used for the file 10 is formed of a transparent resin film made of, for example, polypropylene or PET resin, so that the stored document can be visually recognized.

  Furthermore, in the file 10, two folds 14 and 15 extending in a direction substantially parallel to the welding portion 13 (first side) are formed. Here, the first fold 14 and the second fold 15 are referred to in order from the side closer to the welded portion 13.

  The first folds 14 and the second fold 15 are groove-shaped concave portions formed by Thomson processing, and the first fold 14 is a fold such that the front side of the paper surface is a mountain fold. It is attached. Further, contrary to the first fold 14, the second fold 15 is creased so that the front side in the drawing of FIG. 1 becomes a valley fold.

  The positions of these folds 14 and 15 are such that the second fold 15 overlaps the weld 13 (first side) when the file 10 is folded, and the first fold 14 forms the weld 13 It is disposed at an interval so as to overlap with the opposite side (second side).

  In this way, the file 10 can be folded such that the fold 14 overlaps the side opposite to the weld 13 as shown in FIG. .

  3 (a) is an enlarged cross-sectional view of the first fold 14 of the file 10, and FIG. 3 (b) is an enlarged cross-sectional view of the first fold 14 of the file 10 in a state of containing the document. is there.

  The example shown in FIG. 3A shows a state in which no document is stored in the file 10. As illustrated, when the two sheet bodies 11 are folded along the first fold line 14, the sheet body on the mountain fold side (outside) is called the second sheet body 11b, depending on the thickness of the sheet bodies 11. The positions of the bent portions 14a and 14b differ between the sheet member on the valley folding side (hereinafter referred to as the first sheet member 11a).

  While the position of the bending portion 14b of the first sheet 11a coincides with the position of the first fold 14, the position of the bending portion 14a in the second sheet 11b corresponds to that of the first sheet 11a. It shifts | deviates in the direction away from the welding part 13 rather than the bending part 14b.

  This is because the bending portion 14a of the second sheet 11b is formed so as to wrap around the outside of the first sheet 11a by an amount corresponding to the thickness. The magnitude ΔL of the displacement between the bent portion 14a and the bent portion 14b is approximately the same as the thickness of the second sheet 11b.

  Further, as shown in FIG. 3B, when the document 51 is stored in the file 10, the size ΔL of the positional deviation between the bending portion 14a of the second sheet 11b and the bending portion 14b of the first sheet 11a. Will increase further. The magnitude ΔL of this positional deviation is approximately equal to the sum of the thickness of the second sheet 11 b and the thickness of the document.

  As described above, when the two stacked sheet members are bent, the positions of the bending portions 14a and 14b differ between the first sheet member 11a and the second sheet member 11b. Therefore, when the position of the fold is not appropriate, as described below, the fold and the bent portion do not coincide, and the sheet 11 is wrinkled due to the distortion and the sheet is displaced, and the sheet can not be folded neatly. The problem arises.

  FIG. 4 is a view showing the displacement of the sheet 11 when the file 60 according to the comparative example is folded.

  In the file 60 of FIG. 4, the first fold 14 and the second fold 15 are formed in parallel with the welding portion 13.

  Focusing on the actual bent portion 14a of the file 60, the position of the lower end portion 24c coincides with the first fold 14, while the position of the upper end portion 24d of the bent portion 14a corresponds to the first fold 14. In the direction away from the weld 13. The magnitude ΔL of the deviation is approximately the same as the thickness of the sheet 11a.

  In this manner, when the actual bending portion 14 a deviates from the first fold 14, the second sheet 11 b is in a tensioned state, and a wrinkle or slack is generated in an unintended portion, so that a positional deviation occurs. Can not be folded properly. In the illustrated example, the welded portion 13 does not overlap the fold, and the left side edge of the second sheet 11b is inclined with respect to the left side edge of the first sheet 11a.

  In addition, an unnecessary expansion due to the wrinkles of the sheet 11 occurs in the file 60 in the folded state, and the thickness T is increased.

  Although not shown in particular, when the document is stored in the file 60, the positional deviation between the side of the second sheet 11b and the side of the first sheet 11a is further increased, which makes it more difficult to cleanly fold the sheet. .

  Therefore, in the file 10 according to the present embodiment, as described below, the position of the fold of the second sheet 11b so that the actual bends 14a and 14b and the first fold 14 coincide with each other. change.

  FIG. 5 is a plan view showing the position of the fold of the file 10 according to the embodiment.

  The broken lines in the figure indicate the positions of the folds 14g and 15g (first fold) of the first sheet 11a, and the dashed-dotted lines in the figure indicate the folds 14f and 15f of the second sheet 11b. The position of (the second fold) is shown.

  Focusing on the first fold 14, the first fold 14 g of the valley-folded first sheet 11 a is formed in parallel to the welding portion 13. On the other hand, in the second fold 14f of the second sheet 11b in a mountain fold, the lower end 14c intersects with the first fold 14g, and the upper end 14d is higher than the upper end 14e of the first fold 14g. , And is formed so as to be separated from the welding portion 13 by ΔL. The value of this ΔL is set larger than at least the thickness of the second sheet 11b.

  More preferably, ΔL may be set to be slightly larger than the sum of the thickness of the document sandwiched by the file 10 and the second sheet 11b, and can be set to, for example, about 0.5 mm.

  As described above, in the file 10 of the present embodiment, the second fold line 14f of the second sheet 11b is inclined in consideration of the thickness of the second sheet 11b and the thickness of the document to be stored. The actual bend 14a coincides with the position of the fold 14f and can be neatly folded along the first fold 14.

  On the other hand, the second folds 15f and 15g are parallel to the first folds 14f and 14g. That is, the first fold 15g of the second fold 15 of the first sheet 11a is formed parallel to the first fold 14g of the first fold 14. Further, the second fold 15f of the second fold of the second sheet body 11b is formed in parallel with the second fold 14f of the first fold 14. This is because, in the file 10, the second fold 15 is bent to the opposite side of the first fold 14 so that the displacement of the bending portion generated at the first fold 14 is the second fold 15 It is because it is offset by the position of the bending part which generate | occur | produces. That is, the folds to be attached to the same sheet may be formed in parallel.

  As described above, in the file 10 of the present embodiment, the second fold 14 f is welded at the position in the lateral direction of the upper end 14 d of the second fold 14 f compared to the lateral position of the upper end 14 e of the first fold 14 g. It inclines and forms so that it may separate from 13. Thereby, the position of the actual bending part 14a of the 2nd sheet | seat body 11b and the 2nd fold 14f can be made to correspond, and the tension of the sheet | seat body 11 is suppressed. As a result, the welding side 13 of the file 10 and the second fold 15 overlap, and the left side of the first sheet 11a overlaps with the left side of the second sheet 11b, and the sheet is folded cleanly. Can.

  Hereinafter, a method of manufacturing the file 10 shown in FIGS. 1 and 2 will be described. 6 (a) to 7 (b) are diagrams showing a method of manufacturing the file 10 of FIG.
