In recent years, efforts have been made to differentiate document storage files by increasing added value while suppressing manufacturing costs. From the viewpoint of manufacturing cost, a simple configuration by bending and welding as exemplified in Patent Document 1 is advantageous. Further, even with the configuration exemplified in Patent Document 2 and Patent Document 3, no significant cost increase occurs. However, if the appealing power to appeal the differentiation from other companies can be further enhanced by the new function with respect to these conventional technologies, the added value will be higher and the product will be highly competitive.

As an example, if it becomes possible to sign, seal, mark, write notes, etc. on the document without taking out the document stored in the document storage file in the scene of business negotiations and meetings, it will be possible to use it in a new way that was not available in the conventional product. It becomes more convenient and the added value can be further improved.

The present invention has been made in view of the above circumstances, and a document storage file capable of signing, stamping, marking, writing notes, etc. on a stored document without taking out the stored document while suppressing an increase in manufacturing cost by an extremely simple configuration. The purpose is to provide.

The present invention solves the above problems by means of solutions as described below.

The document storage file according to the present invention is opened with a left side closed by mountain-folding a resin sheet material and a lower side closed by a welded portion formed by welding the mountain-folded sheet material. A front cover and a back cover having an upper side and an open right side are provided, and the front cover is formed with a first tear blocking portion cut out inward from a position close to the welded portion on the right side. Documents are stored between the front cover and the back cover, and the front cover is formed with a first perforation, and the first perforation is formed so as to be connectable to the first tear stopper. At the same time, the cover is formed so as to be divisible into a first area on the upper side and a second area on the lower side.

According to this configuration, the cover can be opened along the perforation as needed, so that the document can be signed, stamped, marked, written in a memo, etc. without taking out the document stored in the document storage file. Become. By opening and expanding the cover along the first perforation, the first area of the cover can be used as an underlay as an example. It is also possible to use an A4 size document storage file as an A3 size underlay. As an example, by providing a pair of cuts on the cover, inserting and holding a card such as a business card or a message card and associating it with a document storage file, it becomes easy to organize the information associated with the card. As an example, by providing a colored portion on the front cover and the back cover so that one side or both sides of the document can be hidden, it becomes easy to manage information according to the importance without exposing the document information. As an example, since the cover can be opened along the first perforation and the left side can be opened along the second perforation, the second area of the cover can be used as a bookmark and sandwiched between documents such as a booklet. Therefore, it is easy to open and show the signature line of a booklet such as a contract, the page for describing important matters, and the page for describing an estimate.

According to the present invention, it is possible to realize a multifunctional document storage file while suppressing an increase in manufacturing cost with an extremely simple configuration.

(First Embodiment)
Hereinafter, the document storage file of the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic front view of the document storage file 1 of the present embodiment, FIG. 2 is a schematic front view showing a partially opened state by turning over the upper right side of the cover 2, and FIG. 3 is a schematic front view. FIG. 5 is a schematic front view showing a state in which the cover 2 is completely opened along the first perforation 17. In this text, for convenience, the words on the left side, right side, upper side, and lower side at the positions shown in FIG. 1 will be used for explanation. Further, in all the drawings for explaining the embodiment, members having the same function may be designated by the same reference numerals, and the repeated description thereof may be omitted.

As shown in FIGS. 1 to 3, the document storage file 1 of the present embodiment is a storage tool for storing documents by sandwiching them between the front cover 2 and the back cover 3 made of a resin sheet material. In the present embodiment, one rectangular sheet material is bent at the center to form a front cover 2 and a back cover 3 connected by a left side 11 which is a closed side. At the same time, at a position facing the left side 11, a right side 13 which is an open side serving as a document loading / unloading portion is formed. That is, the front cover 2 and the back cover 3 have a left side 11 closed by mountain-folding a resin sheet material and a lower side closed by a welded portion 4 formed by welding the mountain-folded sheet material. It has 12, an open upper side 14, and an open right side 13. The welded portion 4 is formed by, for example, ultrasonic welding, heat welding, or a combination of ultrasonic welding and heat welding.

The cover 2 is formed with a first tear blocking portion 15 notched inward from a position close to the welded portion 4 on the right side 13A. The first perforation 17 is formed on the cover 2, and the start position of the first perforation 17 is formed so as to be connectable to the first tear stopper 15, and the cover 2 is connected to the upper first area 2a. It is formed so as to be separable from the lower second area 2b. As an example, the distance between the start position of the first perforation 17 and the left end position of the first tear stopper 15 is 1 [mm] or more and 2 [mm] or less. Further, on the cover 2, a second tear blocking portion 25 cut out inward from a position close to the welding portion 4 on the left side 11 is formed, and the end position of the first perforation 17 is the second tear blocking portion. It is formed so as to be connectable with 25. As an example, the distance between the end position of the first perforation 17 and the right end position of the second tear stopper 25 is 1 [mm] or more and 2 [mm] or less.

The first perforation 17 in the examples of FIGS. 1 to 3 is formed at a position parallel to the lower side 12 (including a position substantially parallel), and the start position of the first perforation 17 is the first split on the right side 13A. The position is close to the stop portion 15, and the end position of the first perforation 17 is a position close to the second tear stop portion 25 on the left side 11.

As shown in FIG. 1, the vertical distance H1 from the start position of the first perforation 17 to the upper end of the welded portion 4 is set within a range of 10 [mm] or more and 50 [mm] or less. Further, the vertical distance H2 from the end position of the first perforation 17 to the upper end of the welded portion 4 is set within a range of 10 [mm] or more and 50 [mm] or less. The interval H1 and the interval H2 correspond to the insertion depth of the insertion portion 8, and the interval H1 and the interval H2 are secured to be 10 [mm] or more, so that the cover 2 is opened along the first perforation 17. Also, the document can be easily inserted by the insertion portion 8. Moreover, by setting the interval H1 and the interval H2 to 50 [mm] or less, the required size can be secured when the cover 2 is used as an underlay. As an example, by setting the interval H1 and the interval H2 to 30 [mm] or less, a sufficient size can be secured when the cover 2 is used as an underlay. As an example, the vertical distance H3 from the start position of the first perforation 17 to the lower side 12 is set to 15 [mm] or more and 55 [mm] or less. Further, the vertical distance H4 from the end position of the first perforation 17 to the lower side 12 is set to 15 [mm] or more and 55 [mm] or less.

Polypropylene, polyethylene terephthalate, polycarbonate, and other known synthetic resins are applied as the material of the sheet material. In particular, polypropylene is excellent in moldability and thermal stability, and is suitable as a material for a sheet material. As an example, the sheet material is polypropylene, and the thickness of the sheet material is set to more than 0.2 [mm] and 0.6 [mm] or less. That is, when the thickness of the sheet material exceeds 0.2 [mm], the document storage file 1 can be easily placed vertically on a shelf, a document storage box, or the like, and the cover 2 is used as an underlay. A sufficient thickness can be secured. Moreover, by reducing the thickness of the sheet material to 0.6 [mm] or less, it is possible to form the welded portion 4 while suppressing an increase in material cost, and the manufacturing cost can be kept within a price competitive range. Further, by reducing the thickness of the sheet material to 0.5 [mm] or less, it is possible to easily form the welded portion 4 while suppressing an increase in material cost, so that a product having excellent price competitiveness can be obtained. As an example, the thickness of the sheet material is set to be more than 0.25 [mm] and less than 0.35 [mm].

The cover 2 has a pair of cuts 9a and 9b at predetermined intervals at a position close to the upper side 14 and a position close to the right side 13A, and a card such as a business card can be inserted and held in the cuts 9a and 9b, respectively. It is a composition. According to this configuration, by inserting and holding a card such as a business card and associating it with the document storage file 1, it becomes easy to organize the information associated with the card. As an example, either the front cover 2 or the back cover 3 has a colored portion, and one or both sides of the document are hidden by the colored portion. This facilitates information management according to importance and the like without exposing document information. As an example, a colored portion is provided on the back cover 3 so that one side of the document is hidden. As an example, a colored portion is provided on each of the front cover 2 and the back cover 3, so that both sides of the document are hidden.

The back cover 3 has a continuous cut line that advances inward from the starting point provided on the outer edge side and then returns to the ending point provided on the outer edge side in the first end region located near the right side 13B. The main holding portion 20 is formed so as to be lockable on the cover 2 by erecting the top portion, which is the position farthest from the start point and the end point, with the line connecting the start point and the end point as the baseline. It also has a first standing operation tab 22 that also serves as an index portion and is provided so as to project outward at the first outer edge portion corresponding to the position of the main holding portion 20. According to this configuration, after the document is sandwiched between the front cover 2 and the back cover 3, the main holding portion 20 is operated so as to stand up and then return, so that the end portion of the document is held by the main holding portion 20. It can be sandwiched and held. In addition, the first standing operation tab 22 also serves as an index unit, and can display and describe index information such as titles corresponding to the contents of a plurality of sorted and stored documents. The documents held by the main holding unit 20 can be clearly grasped.

Subsequently, a method of storing documents using the document storage file 1 will be described with reference to FIGS. 4 and 5. As an example, the first document (document group) P1 is stored between the front cover 2 and the back cover 3, and then the main holding portion 20 on the side closer to the welding portion 4 is raised above the first document P1. The right end of the first document P1 is sandwiched and held by standing up and then returning by the restoring force. Then, the second document (document group) P2 is stored between the cover 2 and the first document P1 previously held by the main holding portion, and then the side far from the welded portion 4 (on the upper side 14). By raising the main holding portion 20 (on the near side) above the second document P2 (here, the topmost document) and then returning it by the restoring force, the right end portion of the second document P2 is sandwiched and held. .. According to the storage method based on this configuration, a plurality of documents can be sorted and stored in a single space formed between the front cover 2 and the back cover 3. That is, in the above configuration example, the first document P1 can be sorted and stored, and the second document P2 can be sorted and stored. The known technique described in Patent Document 3 (Japanese Unexamined Patent Publication No. 2018-058335) described above can be appropriately applied to the present application.

Subsequently, another example of the document storage file 1 will be described with reference to FIGS. 6 and 7. In this example, the first perforation 17 is formed so that the distance from the lower side 12 increases as the position closer to the right side 13A approaches the position closer to the left side 11. With this configuration, documents P1, P2, and P3 can be easily inserted into the insertion portion 8 even when the cover 2 is opened along the first perforation 17, and these documents P1, P2, and P3 can be easily inserted. Can be maintained in the state of being inserted into the insertion portion 8.

As an example, the first document (document group) P1 is stored between the front cover 2 and the back cover 3, and then the main holding portion 20 closest to the upper side 14B is moved above the first document P1. By standing up and then returning it by the restoring force, the right end portion of the first document P1 is sandwiched and held. Then, the second document (document group) P2 is stored between the cover 2 and the first document P1 previously held by the main holding portion 20, and then the intermediate position between the upper side 14B and the lower side 12 By raising the main holding portion 20 above the second document P2 and then returning it by the restoring force, the right end portion of the second document P2 is sandwiched and held. Then, the third document (document group) P3 is stored between the cover 2 and the second document P2 previously held by the main holding portion 20, and then the main on the side closest to the welding portion 4. By raising the holding portion 20 above the third document P3 (here, the document P3 including the topmost document) and then returning it by the restoring force, the right end portion of the third document P3 is sandwiched together with the cover 2. Hold with. Then, if necessary, the cover 2 is opened along the first perforation 17, and the document P3 stored in the document storage file 1 is not taken out, but the document on the top surface of the document is signed, stamped, or marked. Make it possible to write notes. In addition, the cover 2 is used as an underlay as appropriate. Here, when the cover 2 is opened along the first perforation 17, the main holding portion 20 on the side closest to the welding portion 4 sandwiches and holds the right end portion of the third document P3 by the restoring force. As described above, according to the storage method according to the above configuration, it is possible to sort and store a plurality of documents in a single space formed between the front cover 2 and the back cover 3. That is, in the above configuration example, the first document P1 can be sorted and stored, the second document P2 can be sorted and stored, and the third document P3 can be sorted and stored.

As a configuration other than the above, in addition to the above configuration, the left side 11A of the front cover 2 and the left side 11B of the back cover 3 are connected to the upper side 14A of the front cover 2 and the upper side 14B of the back cover 3 to the insertion portion 8. It may form a third perforation. This makes it possible to separate the front cover 2 from the back cover 3 along the first perforations 17 and the third perforations. The separated cover 2 can be used as an underlay. Then, after use, the separated cover 2 is inserted back into the insertion portion 8 as an example.

(Second embodiment)
Hereinafter, the document storage file of the second embodiment of the present invention will be described with reference to the drawings. FIG. 8 is a schematic front view of the document storage file 1 of the present embodiment, FIG. 9 is a schematic perspective view showing an example of the embodiment, and FIG. 10 shows the cover 2 opened along the first perforation 17. It is a schematic perspective view which shows the state. In the second embodiment, the differences from the first embodiment will be mainly described.

In this example, the first perforation 17 on the cover 2 is formed so as to be connectable to the first tear blocking portion 15, and is formed to be connectable to the second tear blocking portion 25, and is formed to be connectable to the second tear blocking portion 25. The eyes 17 are formed so that the distance from the lower side 12 increases as the position closer to the right side 13A approaches the position closer to the left side 11. As a result, even when the cover 2 is opened along the first perforation 17, the document can be easily inserted into the insertion portion 8 and the state in which the document is inserted into the insertion portion 8 can be maintained.

As an example, the vertical distance H1 from the start position of the first perforation 17 to the upper end of the welded portion 4 is set to be 10 [mm] or more and less than 30 [mm]. Moreover, the vertical distance H2 from the end position of the first perforation 17 to the upper end of the welded portion 4 is set to be more than 30 [mm] and 50 [mm] or less. Preferably, the spacing H1 is set to be greater than or equal to 10 [mm] and less than 15 [mm]. Moreover, the interval H2 is set to be more than 15 [mm] and 30 [mm] or less. As an example, the vertical distance H3 from the start position of the first perforation 17 to the lower side 12 is set to be 15 [mm] or more and less than 35 [mm]. Further, the vertical distance H4 from the end position of the first perforation 17 to the lower side 12 is set to be more than 20 [mm] and 55 [mm] or less. As an example, the cover 2 has a pair of cuts 9a and 9b at predetermined intervals at a position close to the upper side 14 and a position close to the right side 13A, and a card such as a business card is inserted into the cuts 9a and 9b, respectively. It is a structure that can be held.

The cover 2 is a second end region located near the right side 13A so as to proceed inward from the second starting point provided on the outer edge side and then return to the second end point provided on the outer edge side. The second notch line is inserted, and the second apex is located at the position farthest from the second starting point and the second end point, with the line connecting the second starting point and the second ending point as the base line. A second fastening portion 30a for separating the cut line is formed, and the secondary holding portion 30 is formed so as to be lockable on the back cover 3 by separating the second fastening portion 30a and raising the second top portion. It also has a second standing operation tab 32 that also serves as a second index portion and is provided so as to project outward at the second outer edge portion corresponding to the position of the sub-holding portion 30. According to this configuration, since the second fastening portion 30a is formed, it is possible to prevent the document P2 from being caught at the position of the sub-holding portion 30 on the cover 2 when the document P2 is inserted. Then, after the document P1 and the document P2 are sandwiched between the front cover 2 and the back cover 3, not only the state before the cover 2 is opened along the first perforation 17, but also the cover 2 is set to the first perforation 17. Even in the open state along the line, the sub-holding unit 30 is operated so as to stand up and then return, so that the sub-holding unit 30 sandwiches both the end of the document P1, the end of the document P2, and the back cover 3. Since it can be held, as shown in FIG. 9, the right side 13A and the right side 13B of the document storage file 1 can be fastened so as not to be separated from each other. The second standing operation tab 32 also serves as an index unit.

Subsequently, a method of storing documents using the document storage file 1 will be described with reference to FIGS. 9 and 10. As an example, the first document (document group) P1 is stored between the front cover 2 and the back cover 3, and then the main holding portion 20 on the side closer to the welding portion 4 is raised above the first document P1. The right end of the first document P1 is sandwiched and held by standing up and then returning by the restoring force. Then, the second document (document group) P2 is stored between the second document (document group) P2 and the first document P1 previously held by the main holding portion 20, and then the side far from the welding portion 4 (the side closer to the upper side 14). ) Is raised above the second document P2 and then returned by the restoring force to sandwich and hold the right end of the second document P2. Then, after the document P1 and the document P2 are sandwiched between the front cover 2 and the back cover 3, the sub-holding portion 30 is operated so as to stand up and then return, so that the end portion of the document P1 is formed by the sub-holding portion 30. And both the edge of the document P2 and the back cover 3 are sandwiched and held.

As described above, according to the storage method according to the above configuration, it is possible to sort and store a plurality of documents in a single space formed between the front cover 2 and the back cover 3. That is, in the above configuration example, the first document P1 can be sorted and stored, and the second document P2 can be sorted and stored. Further, according to the above configuration, the cover 2 can be opened along the first perforation 17 as needed. Therefore, it is possible to sign, seal, mark, write a memo, or the like on the uppermost document of the documents without taking out the documents stored in the document storage file 1. As an example, by opening and expanding the cover 2, the cover 2 can be used as an underlay. As an example, by inserting and holding a card such as a business card or a message card on the cover 2 and associating it with the document storage file 1, it becomes easy to organize the information associated with the card. Then, even when the cover 2 is opened along the first perforation 17, the document can be easily inserted into the insertion portion 8 and the state in which the document is inserted into the insertion portion 8 can be maintained. Further, even when the front cover 2 is opened along the first perforation 17, the sub-holding portion 30 is operated so as to stand up and then return, so that the sub-holding portion 30 causes the end portion and the back cover 3 of the document. Since both of them can be sandwiched and held, the right side 13A and the right side 13B of the document storage file 1 can be fastened so as not to be separated from each other. Therefore, it is possible to quickly retrieve the desired document by referring to the index section while collecting the necessary document groups.

(Third Embodiment)
Hereinafter, the document storage file of the third embodiment of the present invention will be described with reference to the drawings. 11 is a schematic front view of the document storage file 1 of the present embodiment, FIG. 12 is a rear view, FIG. 13 is a schematic perspective view showing an example of the embodiment, and FIG. 14 is a schematic perspective view of the document storage file 1.

In this example, the first perforation 17 is formed so that the distance from the lower side 12 increases as the position closer to the right side 13A approaches the position closer to the left side 11. The start position of the first perforation 17 is formed so as to be connectable to the first retaining portion 15, and the end position of the first perforation 17 is formed so as to be connectable to the second tear stopper portion 25. As an example, the distance between the start position of the first perforation 17 and the left end position of the first tear stopper 15 is 1 [mm] or more and 2 [mm] or less. As an example, the distance between the end position of the first perforation 17 and the right end position of the second tear stopper 25 is 1 [mm] or more and 2 [mm] or less.

Further, in this example, the left side 11 is formed with the second perforation 27, the second perforation 27 is formed so as to be connectable to the first perforation 17, and the first perforation 17 on the left side 11 is formed. The section from the connection point with and to the welded portion 4 on the left side 11 is formed so as to be openable. As an example, the distance between the start position of the second perforation 27 and the lower end position of the second tear stopper 25 is 1 [mm] or more and 2 [mm] or less. As an example, the distance between the end position of the second perforation 27 and the lower side 12 is 5 [mm] or more and 10 [mm] or less.

The back cover 3 advances inward from the first starting point provided on the outer edge side and then returns to the first ending point provided on the outer edge side in the first end region located near the right side 13B. The first cut line is inserted, and the first top portion, which is the position farthest from the first start point and the first end point, is the first line with the line connecting the first start point and the first end point as the baseline. A first fastening portion 20a that separates one cut line is formed, and a main holding portion 20 that is formed so as to be lockable on the cover 2 by being separated from the first fastening portion 20a and having the first top portion stand up. It also has a first standing operation tab 22 that also serves as a first index portion and is provided so as to project outward at the first outer edge portion corresponding to the position of the main holding portion 20. According to this configuration, since the first fastening portion 20a is formed, it is possible to prevent the document P1 from being caught at the position of the main holding portion 20 on the back cover 3 when the document P1 is inserted. Then, after the document P4 is sandwiched between the front cover 2 and the back cover 3, not only the state before the front cover 2 is opened along the first perforation 17, but also the front cover 2 is opened along the first perforation 17. Even in this state, by operating the main holding portion 20 so as to stand up and then return the main holding portion 20, the end portion of the document P4 can be sandwiched and held and fastened by the main holding portion 20. Further, the first standing operation tab 22 is configured to also serve as an index unit.

Subsequently, a method of storing documents using the document storage file 1 will be described with reference to FIGS. 13 and 14. As an example, the cover 2 is opened along the first perforation 17 and divided into the upper first area 2a and the lower second area 2b, and the left side 11 is opened along the second perforation 27. A section from the connection point with the first perforation 17 on the left side 11 to the welded portion 4 on the left side 11 is opened. Then, the fourth document (document group) P4, which is a booklet, is stored between the front cover 2 and the back cover 3, and the second area 2b in a state of being separated from the front cover 2 and the left side 11 is stored. It is sandwiched as a bookmark for opening the description page P4b of the signature line such as the contract in the fourth document P4 and the description page P4a of important matters such as estimates. Further, by raising the main holding portion 20 above the description page P4b of the signature line of the fourth document P4 and then returning it by the restoring force, the right end portion of the signature column description page P4b is sandwiched and held.

As described above, according to the storage method according to the above configuration, the second area of the cover 2 can be used as a bookmark and sandwiched between the documents P4 such as a booklet.
