[0011] As shown in Figures 1 and 5, the file 10 according to this embodiment has a pocket-shaped storage section 40 in the cover body 20. The storage section 40 can store thin (sheet-shaped or card-shaped) items 100 (see Figure 2), such as printed matter or clear folders, in a manner that is visible from the outside of the file 10. The storage section 40 is suitable for use as so-called "visible storage."

[0012] The file 10 includes a cover body 20, a binder 30 (see FIG. 2), and a storage section 40. The cover body 20 is a flexible plate-like body made of a resin material such as polypropylene resin.

[0013] As shown in FIG. 1, the cover body 20 has a front cover 22, a back cover 24, and a spine 26. The front cover 22 is a plate-like member that covers the front side of the booklet to be bound into the file 10. An opening 23 is formed in the front cover 22. The opening 23 penetrates the front cover 22 in the thickness direction. The back cover 24 is a plate-like member that is disposed opposite the front cover 22 and covers the back side of the booklet. The spine 26 connects the front cover 22 and the back cover 24. An eyelet 28 is provided at the top of the spine 26. Note that the eyelet 28 does not have to be provided.

[0014] Cover body 20 has a thin hinge portion 25 at the boundary between front cover 22 and spine 26. Cover body 20 has a thin hinge portion 27 at the boundary between back cover 24 and spine 26. Hinge portion 27 makes it easy to open and close front cover 22 and back cover 24.

[0015] As shown in FIG. 2 , the binding device 30 is joined to the inner surface 260 of the spine 26. The binding device 30 may also be joined to the inner surface 220 of the front cover 22 or the inner surface 240 of the back cover 24. The binding device 30 is, for example, a ring-type metal fitting and has a plurality of ring-shaped binding rods 32. The binding device 30 shown in the figure is a four-hole type binding device 30 and has four binding rods 32. The binding device 30 may also have two binding rods 32. The binding device 30 may also have 30 binding rods 32. Instead of the binding device 30, a booklet (for example, a plurality of pocket sheets, etc.) may be fixed to the spine 26.

[0016] The storage section 40 is a portion for storing the stored item 100. The storage section 40 is fixed to the cover body 20 of the file 10. The storage section 40 is fixed to the cover body 20 to form a pocket structure 12. The cover body 20 and the pocket structure 12 form a file cover structure 13. In this embodiment, the storage section 40 is fixed to the inner surface 220 of the front cover 22. In another aspect, the storage section 40 may be fixed to the inner surface 240 of the back cover 24.

[0017] 1, the storage section 40 is fixed to the cover body 20 (front cover 22) so as to cover the opening 23 of the cover body 20. Therefore, when viewed from outside the file 10, the storage section 40 is exposed from the opening 23 except for the peripheral edge of the storage section 40. Therefore, the items 100 stored in the storage section 40 can be seen from outside the file 10 through the opening 23.

[0018] As shown in FIG. 2, an opening 42 is formed at one end (upper side) of the storage section 40 for inserting and removing the stored item 100. The other end (lower side) of the storage section 40 is closed. The storage section 40 is formed by folding a single transparent resin sheet 40S. A folded portion 44 of the resin sheet 40S is located at the other end (lower side) of the storage section 40. The resin sheet 40S is a transparent or translucent flexible film made of a resin such as polypropylene resin. In FIG. 4, the resin sheet 40S is folded at the location indicated by the imaginary line L. Therefore, the location indicated by the imaginary line L becomes the folded portion 44.

[0019] 1, the direction separating one end of the storage section 40 from the other end thereof is defined as the length direction (direction A) of the storage section 40. The direction perpendicular to the thickness direction (direction C) and length direction of the storage section 40 is defined as the width direction (direction B) of the storage section 40.

[0020] In FIG. 2, the storage section 40 has a first resin sheet section 51 and a second resin sheet section 52. The first resin sheet section 51 and the second resin sheet section 52 are integrally connected via a folded section 44. A storage area 40R for storing an object 100 to be stored is formed between the first resin sheet section 51 and the second resin sheet section 52. The first resin sheet section 51 and the second resin sheet section 52 are joined to the cover body 20 (front cover 22). The first resin sheet section 51 and the second resin sheet section 52 are joined to the cover body 20 by, for example, fusion bonding. The first resin sheet section 51 and the second resin sheet section 52 may also be joined to the cover body 20 by adhesive bonding.

[0021] A pair of first side edge portions 51S located on both sides of the first resin sheet portion 51 in the width direction are joined to the cover body 20. In each of the pair of first side edge portions 51S, the central portion in the length direction is a non-joined region 51R that is not joined to the cover body 20. The non-joined region 51R can also be expressed as a non-fused region or a non-adhesive region.

[0022] The first resin sheet portion 51 has a first sheet main body 54, a pair of first joint tabs 56, and a pair of second joint tabs 58. The first sheet main body 54 forms one wall of the storage section 40 in the thickness direction. The first sheet main body 54 has a hole portion 55. The hole portion 55 penetrates the first sheet main body 54 in the thickness direction. The first sheet main body 54 has a substantially rectangular shape.

[0023] The pair of first joint tabs 56 are provided on one side (upper side) of the first side edge portion 51S in the length direction. The pair of first joint tabs 56 protrude from both sides of the first sheet main body 54 in the width direction. The pair of first joint tabs 56 extend in the length direction of the storage section 40. The pair of first joint tabs 56 are joined to the cover body 20 (front cover 22).

[0024] The pair of second joint tabs 58 are provided on the other side (lower side) of the first side edge portion 51S in the length direction. The pair of second joint tabs 58 protrude from both sides of the first sheet main body 54 in the width direction. The pair of second joint tabs 58 extend in the length direction of the storage section 40. The length of the pair of first joint tabs 56 and the length of the pair of second joint tabs 58 may be the same or different. The pair of second joint tabs 58 are joined to the cover body 20 (front cover 22).

[0025] The non-bonded region 51R of the pair of first side edge portions 51S is provided between the first joining tab 56 and the second joining tab 58. In each of the pair of first side edge portions 51S, a recess that is relatively recessed in the width direction is formed between the first joining tab 56 and the second joining tab 58 (see FIG. 4). This recess is the non-bonded region 51R.

[0026] In the longitudinal direction (direction A), the length of the non-bonded region 51R is, for example, one-fourth or more of the length of the first sheet main body 54. The length of the non-bonded region 51R is preferably one-third or more of the length of the first sheet main body 54. In FIG. 2, the length of the non-bonded region 51R is approximately one-third of the length of the first sheet main body 54.

[0027] As shown in Fig. 3, the second resin sheet portion 52 overlaps the first resin sheet portion 51. The second resin sheet portion 52 is disposed between the first resin sheet portion 51 and the cover body 20 (specifically, the front cover 22). Therefore, the first resin sheet portion 51 covers the second resin sheet portion 52. A pair of second side edge portions 52S located on both sides of the second resin sheet portion 52 in the width direction are joined to the cover body 20 (the front cover 22).

[0028] As shown in Fig. 4, the second resin sheet portion 52 has a second sheet main body 62 and a pair of third joining tabs 64. The second sheet main body 62 forms the other wall of the storage section 40 in the thickness direction (direction C). When viewed in the thickness direction, the second sheet main body 62 has a substantially rectangular shape. As shown in Fig. 2, one end (upper end) of the second sheet main body 62 in the length direction is joined to the cover body 20.

[0029] As shown in Fig. 4, the pair of third joint tabs 64 are provided at the center of the pair of second side edge portions 52S in the longitudinal direction. The pair of third joint tabs 64 protrude from both sides of the second sheet main body 62 in the width direction. Therefore, in each of the pair of second side edge portions 52S, both sides (upper and lower) of the third joint tab 64 in the longitudinal direction are relatively recessed inward in the width direction. The pair of third joint tabs 64 extend in the longitudinal direction of the storage section 40. As shown in Fig. 3, the pair of third joint tabs 64 are joined to the cover body 20 (front cover 22).

[0030] As shown in FIG. 2, a pair of third joint tabs 64 are located between a pair of first joint tabs 56 and a pair of second joint tabs 58. Therefore, on one side in the width direction, the first joint tab 56, the second joint tab 58, and the third joint tab 64 are aligned in a straight line. On the other side in the width direction, the first joint tab 56, the second joint tab 58, and the third joint tab 64 are aligned in a straight line. A small gap CL1 is formed between the adjacent first joint tabs 56 and the third joint tab 64. A small gap CL2 is formed between the adjacent third joint tabs 64 and the second joint tab 58. Note that on one side in the width direction, the first joint tab 56, the second joint tab 58, and the third joint tab 64 do not have to be aligned in a straight line. On the other side in the width direction, the first joint tab 56, the second joint tab 58, and the third joint tab 64 do not have to be aligned in a straight line.

[0031] This embodiment has the following advantages.

[0032] Since the center in the longitudinal direction of the first side edge portion 51S is not joined to the cover body 20, adhesion between the first resin sheet portion 51 and the second resin sheet portion 52 is suppressed at the center in the longitudinal direction of the storage section 40. This reduces sliding resistance when inserting the stored item 100 into the storage section 40. This makes it possible to easily store the stored item 100 in the storage section 40.

[0033] The first resin sheet portion 51 has a pair of first joint tabs 56 protruding from the first sheet main body 54 and a pair of second joint tabs 58 protruding from the first sheet main body 54, and a non-jointed region 51R is provided between the first joint tabs 56 and the second joint tabs 58. With this configuration, the center of the first side edge portion 51S in the length direction can be made into the non-jointed region 51R, thereby effectively suppressing adhesion between the first resin sheet portion 51 and the second resin sheet portion 52 in the center.

[0034] The second resin sheet portion 52 has a pair of third joint tabs 64 protruding from the second sheet main body 62, and the pair of third joint tabs 64 are located between the pair of first joint tabs 56 and the pair of second joint tabs 58. With this configuration, the storage section 40 can be joined to the cover body 20 over substantially the entire length on both sides of the storage section 40 in the width direction, thereby ensuring sufficient joining strength of the storage section 40 to the cover body 20.

[0035] The storage section 40 is formed by folding a single resin sheet 40S, and the first resin sheet section 51 and the second resin sheet section 52 are integrally connected via the folding section 44. With this configuration, the close contact between the first resin sheet section 51 and the second resin sheet section 52 at the other end side (lower side) of the storage section 40 is suppressed by the elastic restoring force (springback effect) of the folding section 44. This makes it possible to further reduce the sliding resistance when the stored item 100 is inserted into the storage section 40.

[0036] The first and second joint tabs 56 and 58 on the first resin sheet portion 51 and the third joint tab 64 on the second resin sheet portion 52 are welded to the cover body 20 at offset positions, preventing three sheets from being stacked on top of each other and enabling good welding. In other words, the third joint tab 64 is welded directly to the cover body 20 without overlapping the first and second joint tabs 56 and 58, allowing the storage section 40 having the first and second resin sheet portions 51 and 52 to be welded to the cover body 20 with good welding strength.

[0037] Instead of the above-described storage section 40, a storage section 41 according to a modified example shown in FIG. 6 may be employed. A fourth joint tab 66 joined to the cover body 20 is provided on the other end (lower end) of the storage section 41. The fourth joint tab 66 is joined to the inner surface 220 of the front cover 22. The fourth joint tab 66 protrudes downward from the folded portion 44 (the lower side 410 of the storage section 41). The fourth joint tab 66 protrudes (extends) from the first resin sheet portion 51. The fourth joint tab 66 extends in the width direction of the storage section 41. The folded portions 44 are located on both sides of the fourth joint tab 66.

[0038] As shown in FIG. 7, the resin sheet 41S before folding has a notch 68 formed in the second resin sheet portion 52 (second sheet main body 62) at a location adjacent to the imaginary line L (folded portion 44). The notch 68 reaches the imaginary line L. This notch 68 forms a fourth joint tab 66. By folding the resin sheet 41S at the imaginary line L, the fourth joint tab 66 protrudes downward as shown in FIG. 6. By providing the fourth joint tab 66 in this way, it is possible to eliminate a gap between the lower part of the storage section 41 and the cover body 20.
