Further, a transparent pocket 4 for storing a heading is provided so as to cover the boundary between the back cover main body 27 and the bent portion 29 on the outer surface of the back cover 3.

Next, the assembly order of this file F will be described.

FIG. 11 is a developed view of a synthetic resin sheet S for forming a storage portion 1 having gussets 6 and 7, a front cover 2, and a back cover 3, which form a main part of the file F. In this sheet S, the same reference numerals are given to the parts corresponding to the respective constituent parts of the completed file F. That is, the storage unit 1, the front cover 2, and the back cover 3 are integrally formed by using a common sheet S. From this unfolded state, first, the main folding line 5c of the outer wall 5 is bent to superimpose the front cover 2 on the inner surface of the back cover 3. Then, the boundary fold lines 6a forming the boundary between the upper and lower gussets 6 and 7 and the outer wall 5 of the storage portion 1 are made to have a crease, and the inclined fold lines 19c and 23c of the gusset forming members 19, 23, 21 and 25, respectively. While bending the 21c and 25c, the slits 19s and 21s of one gusset forming member 19 and 21 are inserted through the extending end sides 23a and 25a of the other gusset forming member 23 and 25, and both gusset forming members 19 and 23 on the upper side are inserted. The back surfaces of the extension end sides 19a and 23a in the above and the back surfaces of the extension end sides 21a and 25a of the lower gusset forming members 21 and 25 are brought into close contact with each other. FIG. 12 shows a state in which the above operation is completed. In this state, the extending end sides 19a and 23a of the upper gusset forming members 19 and 23 in which the back surfaces are brought into close contact with each other and the extending end sides 21a and 25a of the lower gusset forming members 21 and 25 are welded to each other, respectively. Join by processing. In this state, the welding work of the pocket 4 for storing the heading is also performed on the outer surface of the back cover 3. The pattern-imparting portion in FIG. 12 shows a region to be welded.

When the above work is completed, the outer walls 5 of the storage unit 1 are separated from each other so that the storage unit 1 is in the unfolding posture (E), and the outer walls 5 are brought close to each other while bending the boundary folding lines 6a and 7a. Both gussets 6 and 7 are inverted and stored in the storage portion 1, the folding line 3a between the folded portion 29 of the back cover 3 and the main body of the back cover 3 is bent, and the bent portion 29 is put on the outer surface of the front cover 2. And the completed file F shown in FIGS. 1 to 10 is obtained.

With the file F having such a configuration, when the front cover 2 and the back cover 3 are opened to the left and right from the folding posture (H) shown in FIGS. 1 to 3, the storage portion 1 passes through the intermediate posture shown in FIG. The deployment posture (E) shown in 5 is obtained. In this process, the upper and lower gussets 6 and 7 are deformed as follows. That is, in the folded posture (H), not only the extending portions 15 and 17 but also the gusset main bodies 11 and 13 are folded in a plate shape. When the unfolding posture (E) is set from this posture through the intermediate posture, the gusset main bodies 11 and 13 gradually expand while maintaining the state in which the extending portions 15 and 17 protrude into the storage space 1s, and the unfolding posture (E). When E) is reached, the gusset bodies 11 and 13 of the gussets 6 and 7 are in a substantially horizontal state. In this state, the extension end sides of the extension portions 15 and 17 are exposed from the storage space 1s. FIG. 6 shows a state in which the extending portions 15 and 17 of the gussets 6 and 7 project outward from the open end of the storage space 1s, that is, the tip 5b of the outer wall 5.

In this way, if the gusset bodies 11 and 13 of the gussets 6 and 7 are in a substantially horizontal state in the unfolded posture (E) and a part of the extending portions 15 and 17 protrudes from the storage space 1s, the protruding portion is removed. It is possible to store an object to be stored such as a document in the storage unit 1 as a guide, and it is possible to solve the problem that the gussets 6 and 7 are in the way and it is difficult to insert the document or the like. Moreover, since the gussets 6 and 7 of this file F include the extension portions 15 and 17 extending into the storage portion 1, even if the opening width of the storage portion 1 is set large, the gussets 6 and 7 are provided. It is possible to prevent or suppress the problem that the file is inverted and protrudes outward. Further, since the storage space 1s is divided into the front cover 2 side and the back cover 3 side by the extension portions 15 and 17 of the gussets 6 and 7, the extension portions 15 and 17 of the gussets 6 and 7 are stored in the storage space. It can also be used as a partition for 1s. In addition, by ensuring a sufficient length of the extension portions 15 and 17, a clear holder or the like is covered on the front cover 2 side and the back cover 3 side of the extension portions 15 and 17 in the storage space 1s. When the front cover 2 and the back cover 3 are unfolded and the storage portion 1 is in the unfolded posture (E) with the stored items arranged in a well-balanced manner (for example, the same number on the front cover 2 side and the back cover 3 side), the items to be stored Can be prevented from being placed unevenly over the extending portions 15 and 17 (the amount of the items to be stored is different on the front cover 2 side and the back cover 3 side).

The present invention is not limited to the embodiments described above.

For example, in the above-described embodiment, the gusset is integrally extended from the edge of both outer walls of the storage portion, but as shown in FIGS. 13 and 14, the gusset 7 is separated from the outer walls 5 of the storage portion 1. It may be a body. That is, the gusset 7 in this file F2 is composed of gusset forming members 21 and 25 in which the base end folded portions 21z and 25z are welded to the inner surfaces of the outer walls 5 of the corresponding storage portions 1, respectively. It is made by welding the tip side 21x and 25x of 25 in a state of being overlapped so as to be in close contact with each other. Then, the extending portion 17 of the gusset 7 is formed by the tip sides 21x and 25x of the gusset forming members 21 and 25, and the gusset body 13 is formed by the base end sides 21y and 25y of the gusset forming members 21 and 25. doing. Also in this file F2, when the storage portion 1 is in the unfolded posture (E), the gusset main body 13 is unfolded in a substantially horizontal state, and a part of the extending portion 17 is an opening of the storage space 1. It is exposed to the outside from the end, that is, the tip 5b of the outer wall 5. Although only the lower gusset 7 provided between the lower edges 5f of the outer wall 5 of the storage portion 1 is shown in FIGS. 13 and 14, the above-mentioned is also shown between the upper edges of the outer wall 5 of the storage portion 1. An upper gusset having the same structure as the lower gusset 7 is arranged. Further, in FIGS. 13 and 14, the same or similar parts as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

Further, the configuration of the storage portion is not limited to that of the above-described embodiment, and various configurations can be considered. However, if the configuration of the above-described embodiment is adopted, there is a problem that it is difficult to insert a document or the like because the gusset becomes an obstacle while the opening width at the time of unfolding the front cover and the back cover is large due to the simple configuration. In addition to being able to prevent or suppress the occurrence, the gusset is folded inside the storage section when it is in the folded position, so it does not get in the way when it is stored in the file box.

On the other hand, the configuration of the gusset main body and the extension portion is not limited to that of the above-described embodiment, and the flexible gusset main body and the extension that is produced from the intermediate portion in the width direction of the gusset main body toward the storage portion side. Other configurations may be adopted, such as all of the portions being made of the same member. However, if the configuration of the above-described embodiment is adopted, the extension portion and the gusset body are formed by connecting the extension end sides of the sheet-shaped gusset forming member, so that the gusset forming member can be easily manufactured.

In addition, the shape of the gusset when the gusset is installed and deployed is not limited to that of the above-described embodiment, and other configurations may be adopted. For example, a gusset having an extension portion that is displaced during deployment and exposed from the storage space is arranged only between the lower edges of both outer walls, and only one flexible sheet is provided between the upper edges of both outer walls. As an example, there is a configuration in which the gussets formed by using the above are arranged, and a structure in which the shape of the gusset in the unfolded posture is V-shaped or U-shaped in cross section protruding toward the storage space side. However, if the configuration of the above-described embodiment is adopted, the extension portion can be used as a guide when storing the stored object in the storage space, so that the stored object can be easily inserted into the storage space.

Then, in the above-described embodiment, the storage portion is integrally formed with the front cover and the back cover corresponding to both outer walls via fold lines, and the fold lines are inclined so that the outer walls of the outer wall may be inclined. By setting the length of the lower edge to a value larger than the length of the upper edge, the phenomenon that the object to be stored hangs down during storage is suppressed, but the length of the upper edge and the lower edge of the outer wall It does not prevent the length from being equal to or setting the length of the upper edge of the outer wall to a value larger than the length of the lower edge.

In addition, various changes may be made as long as the gist of the present invention is not impaired.
