[0010] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, some of the components in the embodiments described below are substituted or substantially identical to those easily substituted by those skilled in the art.

[0011] [Embodiment] The document storage bag 1 shown in Figures 1 and 2 is a bag-shaped bag, also known as a communication bag. For example, the document storage bag 1 is designed to hold documents (printouts, etc.) distributed at elementary schools, etc., so that children can take them home and hand them over to their parents or guardians. The size of such documents is, for example, A4 size. The document storage bag 1 is formed in a roughly rectangular shape with short sides 101a, 101b and long sides 102a, 102b so that it can hold A4 size documents.

[0012] In the following explanation, the thickness direction of the document storage bag 1 (the direction perpendicular to the plane of the paper in Figure 1) will be referred to as the thickness direction X, the direction parallel to the short sides 101a and 101b of the document storage bag 1 will be referred to as the short side direction Y, and the direction parallel to the long sides 102a and 102b of the document storage bag 1 will be referred to as the long side direction Z. The thickness direction X, the short side direction Y, and the long side direction Z intersect each other orthogonally.

[0013] As shown in Figures 1 and 2, the document storage bag 1 has a first sheet 110 and a second sheet 120 arranged opposite each other in the thickness direction X. A partition plate 130 is placed between the first sheet 110 and the second sheet 120. The document storage bag 1 is also provided with a connecting part 140 that connects the first sheet 110 and the second sheet 120.

[0014] As shown in Figure 3, the document storage bag 1 has a document storage section 10 inside in which documents are stored. The document storage section 10 is divided by a partition plate 130 between a first sheet 110 and a second sheet 120. The document storage section 10 includes a first document storage section 11 formed between the first sheet 110 and the partition plate 130, and a second document storage section 12 formed between the second sheet 120 and the partition plate 130.

[0015] As shown in FIGS. 1 and 2, the document storage bag 1 is provided with an opening / closing connection portion 150 that connects the first sheet 110 and the second sheet 120 in an openable / closable manner. In the present embodiment, the opening / closing connection portion 150 is constituted by a fastener. FIGS. 1 and 2 show a state in which the fastener, which is the opening / closing connection portion 150, is closed. The document storage bag 1 shown in FIG. 6 shows a state in which the fastener, which is the opening / closing connection portion 150, is open.

[0016] As shown in FIG. 1, on the outer surface of the first sheet 110, there is provided a pocket-shaped memo insertion portion 104 into which memo pieces of paper or the like can be inserted and stored. The memo insertion portion 104 is formed in a substantially long rectangular shape with the short side direction Y as the longitudinal side. The memo insertion portion 104 is formed by sewing a substantially long rectangular transparent resin sheet piece to one side and the other side in the long side direction Z and the other side in the short side direction Y with respect to the first sheet 110. A memo piece of paper can be inserted into the memo insertion portion 104 from one side in the short side direction Y.

[0017] The first sheet 110 and the second sheet 120 are arranged to face each other in the thickness direction X by folding a single resin sheet 100 (see FIG. 4). The resin sheet 100 can be constituted by, for example, EVA (ethylene vinyl acetate copolymer) resin. The first sheet 110 and the second sheet 120 are of the same size and are formed in a substantially long rectangular shape with the long side direction Z as the long side. Hereinafter, the short sides 101a, 101b and the long sides 102a, 102b of the document storage bag 1 also refer to the short sides 101a, 101b and the long sides 102a, 102b of the first sheet 110 and the second sheet 120.

[0018] The connecting portion 140 of the document storage bag 1 includes a folding portion 141 where the first sheet 110 and the second sheet 120 are arranged to face each other in the thickness direction X by folding back a single resin sheet 100. The folding portion 141 is the end portion 107 of the first sheet 110 and the second sheet 120, which is the other short side 101b in the long side direction Z of the document storage bag 1. Also, at one short side 101a in the long side direction Z of the document storage bag 1, the end portions 112, 121 of the first sheet 110 and the second sheet 120 (see FIGS. 1 and 2) (that is, the ends of the resin sheet 100) are arranged to face each other in the thickness direction X.

[0019] As shown in FIGS. 1 and 2, the first sheet 110 and the second sheet 120 have a curved corner portion 105 with a curved shape at the corner extending from one short side 101a in the long side direction Z to one long side 102a in the short side direction Y. The other three corner portions are right-angled corner portions 106. The opening and closing connecting portion 150 is provided including the curved corner portion 105 extending from one short side 101a in the long side direction Z to one long side 102a in the short side direction Y in the first sheet 110 and the second sheet 120.

[0020] The partition plate 130 is formed to be slightly smaller than the first sheet 110 and the second sheet 120, and has a substantially long rectangular shape with the long side direction Z as the longitudinal side. The partition plate 130 is harder than the resin sheet 100 and is formed of an opaque resin plate. The partition plate 130 can be constituted by, for example, a PP (polypropylene) resin plate. The partition plate 130 suppresses and protects the stored documents stored in the document storage bag from being folded. [[ID=Ten]]

[0021] Furthermore, the connecting portion 140 of the document storage bag 1 includes a wrapping connecting portion 142 provided on the other side of the document storage bag 1 in the short-side direction Y. As shown in Figure 3, the wrapping connecting portion 142 is formed by sandwiching and sewing together the ends 111 and 121 of the first sheet 110 and the second sheet 120 on the other side in the short-side direction Y with a cloth-like member 142a. In other words, the cloth-like member 142a is provided on the long side 102b on the other side in the short-side direction Y of the document storage bag 1, extending from the first sheet 110 to the second sheet 120, and is sewn together from one end to the other end in the long-side direction Z of the first sheet 110 and the second sheet 120 along the direction in which the long side 102b extends.

[0022] The encasing connection portion 142 has a partition plate fixing portion 142b that is sewn together with the partition plate 130 sandwiched between the first sheet 110 and the second sheet 120. More specifically, the partition plate fixing portion 142b of the encasing connection portion 142 is sewn together with the fabric-like member 142a provided on the outside of the first sheet 110 and the second sheet 120, by sandwiching the other end 131 of the partition plate 130 in the short side direction Y with the portions including the other ends 111 and 121 of the first sheet 110 and the second sheet 120 in the short side direction Y. The partition plate 130 is fixed between the first sheet 110 and the second sheet 120 by the partition plate fixing portion 142b. The ends of the fabric-like member 142a in the long side direction Z on one side and the other side on the other side are folded back and sewn together to form a folded-back stopper portion 142a1, as shown in Figure 2.

[0023] As shown in Figures 1 and 2, the partition plate 130 has an end 132 on one of its short sides in the long side direction Z that is separated by a distance D1 from the ends 112 and 122 of the short side 101a on one of its short sides in the long side direction Z on the first sheet 110 and the second sheet 120. The partition plate 130 also has an end 133 on the other short side in the long side direction Z that is separated by a distance D2 from the folded portion 141 (the end 107 of the short side 101b on the other short side in the long side direction Z on the first sheet 110 and the second sheet 120). Furthermore, the partition plate 130 has an end 134 on one of its long sides in the short side direction Y that is separated by a distance D3 from the ends 113 and 123 of the long side 102a on one of its short sides in the short side direction Y on the first sheet 110 and the second sheet 120. Note that distance D1 is greater than distance D2.

[0024] The document storage bag 1 is carried, for example, by a child in their school bag. Here, the document storage bag 1 may be formed to be slightly larger than A4 size so that it can store A4 size documents. On the other hand, the storage compartment of the school bag may be formed so that A4 size textbooks can be stored vertically. In this case, the document storage bag 1 is placed in the school bag with the curved corner 105 and memo insertion part 104 as markers, so that the short side 101a is on top. When the document storage bag 1 is placed in the storage compartment of the school bag and the lid of the school bag is closed, the inner surface of the lid of the school bag and the short side 101a of the document storage bag 1 may interfere with each other. Here, as mentioned above, the end 132 of the partition plate 130 and the ends 112 and 122 of the first sheet 110 and the second sheet 120 are separated by a distance D1. Therefore, the first sheet 110 and the second sheet 120 on the shorter side 101a side of the document storage bag 1 interfere with the inner surface of the lid of the school bag and bend. Thus, the printed materials stored in the document storage bag 1 are supported by the partition sheet 130, preventing them from bending.

[0025] As mentioned above, the document storage bag 1 has a folded portion 141 formed on the other short side 101b in the long side direction Z of the document storage bag 1. In other words, the document storage bag 1 has a folded portion 141 formed on the opposite side (the other side in the long side direction Z) from the end 132 on one side in the long side direction Z of the partition plate 130. To put it another way, the folded portion 141 is not provided on the connecting portion 140 on the other side in the short side direction Y. For example, if the folded portion 141 is folded many times in a direction intersecting the fold line 141a (see Figure 4), damage such as tearing may occur. However, in this embodiment, the document storage bag 1 is stored in the school bag with the curved corner portion 105 side facing upwards, so the folded portion 141 is not folded, and damage such as tearing of the folded portion 141 is suppressed.

[0026] Furthermore, even if the encasing connection portion 142 or the opening / closing connection portion 150 is bent within a distance D1, the ends 111, 121 and 113, 123 of the first sheet 110 and the second sheet 120 are not directly connected to each other, so they can be bent flexibly, making the first sheet 110 and the second sheet 120 less susceptible to damage.

[0027] Thus, the distance D1 is set to a distance such that the first sheet 110 and the second sheet 120 can bend through one end 132 in the long side direction Z of the partition plate 130. By setting the distance D1 to be greater than the distance D2, the document storage bag 1 can be made sized to fit into a school bag, while also having a region (defined by the distance D1) that can be bent upwards when stored in the school bag.

[0028] Furthermore, as shown in Figure 1, the document storage bag 1 includes a first sheet pattern 200 provided on the first sheet 110 and consisting of a predetermined pattern, and a partition plate pattern 300 provided on the partition plate 130 and consisting of a predetermined pattern different from the first sheet pattern 200. As shown in Figure 4, the first sheet pattern 200 includes a first sheet specific area 210, a diagram description area 220, and an owner description area 230. The first sheet specific area 210 has a roughly cloud-shaped outline. The first sheet specific area 210 includes a black-filled area 211, an unfilled area of ​​the first sheet (unfilled area 212), and a first sheet message area 213 formed in an outline shape within the filled area 211.

[0029] In this embodiment, the unfilled area 212 of the first sheet consists of two four-leaf clover-shaped unfilled areas 212a and four circular unfilled areas 212b. In the first sheet specific area 210 of Figure 4, the four-leaf clover-shaped unfilled areas 212a are located on the upper side, and the circular unfilled areas 212b are located on the lower side. The two four-leaf clover-shaped unfilled areas 212a and the four circular unfilled areas 212b are spaced apart from each other in the direction of the shorter side Y, and the area between them is filled in, forming a filled area 211. The first sheet message area 213 includes at least one of characters, figures, or symbols, and in this embodiment, it is located in the filled area 211 between the upper four-leaf clover-shaped unfilled area 212a and the lower circular unfilled areas 212b.

[0030] In this embodiment, the first sheet message section 213 has the word "Mitene" (look at) formed in an outline shape (in other words, in outline form) within the filled area 211. Also in this embodiment, the diagram section 220 has a diagram of three small birds perched on a branch. The owner information section 230 has fields for "Year," "Class," and "Name" within a roughly elongated rectangular frame with rounded corners.

[0031] On the other hand, as shown in Figure 5, the partition plate 130 is provided with a partition plate pattern 300 consisting of a predetermined pattern different from the first sheet pattern 200. The partition plate pattern 300 includes a partition plate specific area 310 and a figure-indicated area 320. The partition plate specific area 310 has a roughly cloud-shaped outline, similar to the first sheet specific area 210. The partition plate specific area 310 includes a black-filled area 311 and an unfilled partition plate unfilled area 312.

[0032] The unfilled portion 312 of the partition plate is formed with two four-leaf clover-shaped unfilled portions 312a, four circular unfilled portions 312b, and two smaller four-leaf clover-shaped unfilled portions 312c that are smaller than the four-leaf clover-shaped unfilled portions 312a. In the partition plate specific region 310, the two four-leaf clover-shaped unfilled portions 312a are located on the upper side, and the four circular unfilled portions 312b are located on the lower side. The two four-leaf clover-shaped unfilled portions 312a and the four circular unfilled portions 312b are located close to or in contact with each other in the approximately short-side direction Y. The two small four-leaf clover-shaped unfilled sections 312c are positioned on both sides of the two four-leaf clover-shaped unfilled sections 312a and the four circular unfilled sections 312b in the short-side direction Y.

[0033] The partition plate specific area 310 has a partition plate message area 313 formed in the unfilled partition plate non-filled area 312, which includes at least one of letters, figures, or symbols. In this embodiment, the partition plate message area 313 is formed by filling in the letters "yo" and "ku" provided in each of the two four-leaf clover-shaped non-filled areas 312a of the partition plate specific area 310, and filling in the letters "de," "ki," "ta," and "ne" provided in each of the four circular non-filled areas 312b.

[0034] Furthermore, in this embodiment, the diagram section 320 contains a diagram of a bird resembling an owl, and diagrams of the face and parts of the feet of a small bird.

[0035] The first sheet design 200 and the partition plate design 300 are positioned to overlap each other. The unfilled portion 212 of the first sheet and the unfilled portion 312 of the partition plate are positioned to overlap each other. More specifically, the two four-leaf clover-shaped unfilled portions 212a, 312a and the four circular unfilled portions 212b, 312b are positioned to overlap each other. The four-leaf clover-shaped unfilled portion 212a and the circular unfilled portion 212b of the first sheet unfilled portion 212 are configured with unfilled areas that expose the partition plate message portion 313. In addition, the first sheet message portion 213 is positioned so as not to overlap with the partition plate message portion 313.

[0036] When no documents are inserted into the document storage bag 1 (non-storage state), the first sheet pattern 200 and the divider plate pattern 300 overlap and are visible from the outside, as shown in Figure 1. Here, the first sheet pattern 200 and the divider plate pattern 300 are colored in the same color, black. In particular, the first sheet specific area 210 and the divider plate specific area 310 (each filled area 211, 311) are filled in with the same color, black. The first sheet message section 213 is positioned to overlap with the filled area 311 in the divider plate specific area 310. As a result, the black filled area 311 is exposed from the first sheet message section 213, where the words "Mite ne" are formed in an outline. Consequently, the contour shape of the first sheet message section 213, that is, the boundary between the filled area 211 of the first sheet specific area 210 and the filled area 311 of the partition plate specific area 310 exposed from the first sheet message section 213, becomes difficult to see, and thus the words "Mite ne" (first sheet message section 213) become difficult to see.

[0037] Here, the resin sheet 100, including the first sheet 110, has a textured finish (pearlescent finish) applied to at least its outer surface. This textured finish is a surface treatment that reduces the adhesion of the resin sheet 100 to, for example, textbooks. In addition to the textured finish, other surface treatments that reduce adhesion can also be applied. In this case, the first sheet 110 has a lower light transmittance compared to when it is not textured. Therefore, the partition plate pattern 300 is visible with a lower density when viewed through the first sheet 110. Accordingly, the first sheet pattern 200 in this embodiment is formed with a lower density than the partition plate pattern 300. As a result, even when the first sheet pattern 200 and the partition plate pattern 300 are superimposed and viewed, their densities appear to be the same, allowing the superimposed patterns to be viewed without any sense of incongruity, and further reducing the visibility of the first sheet message section 213. In other words, the density of the first sheet pattern 200 is set to be equivalent to the density when the partition plate pattern 300 is viewed through the first sheet 110, which has a textured finish.

[0038] As shown in Figure 6, when using the document storage bag 1, for example, an elementary school student may take home a printout P1 distributed at school as a document to be stored. In this case, the student opens the zipper, which is the opening and closing connection part 150 of the document storage bag 1, and stores the printout P1 in the first document storage section 11 (see Figure 4) between the first sheet 110 and the partition plate 130, thus putting the document into a stored state.

[0039] As shown in Figure 7, the partition plate pattern 300 on the partition plate 130 is obscured by the print P1 and becomes invisible from the outside. Therefore, only the first sheet pattern 200 is visible from the outside. When the child takes the document storage bag 1 home and removes the print P1 from the document storage bag 1, the overlapping pattern of the first sheet pattern 200 and the partition plate pattern 300 becomes visible, as shown in Figure 1.

[0040] When print P1 is stored in the first document storage section 11, as shown in Figure 7, the child can see the first sheet message section 213. When print P1 is removed, as shown in Figure 1, the first sheet message section 213 is no longer visible, and the partition plate message section 313, which is positioned to overlap with the uncolored section 212 of the first sheet, becomes visible. In this embodiment, the first sheet message section 213 consists of the words "Look at it," and the partition plate message section 313 consists of the words "Well done." In other words, when print P1 is stored in the first document storage section 11, the document storage bag 1 displays the message "Look at it" to remind the child to hand print P1 to a parent or guardian. When print P1 is removed and the first document storage section 11 is not in a stored state, the document storage bag 1 gives the child the message "Well done," motivating them to remember to take the next set of school handouts home and give them to their parents or guardians. In this way, the partition message section 313 and the first sheet message section 213 are formed with corresponding messages.

[0041] In other words, in the document storage bag 1, when there is no document stored in the first document storage section 11 between the first sheet 110 and the divider plate 130 (the state shown in Figure 1), the divider plate message section 313 is exposed and visible from the uncolored section 212 of the first sheet, while the first sheet message section 213 is obscured by overlapping with the specific area 310 of the divider plate.

[0042] Furthermore, in the document storage bag 1, when the document storage bag 1 is in a storage state (state shown in Figure 7) where the document storage document, print P1, is located in the first document storage section 11 between the first sheet 110 and the divider plate 130, the divider plate design 300 is obscured by print P1, the divider plate message section 313 is not exposed from the uncolored section 212 of the first sheet, and the first sheet message section 213 is visible because it overlaps with print P1.

[0043] In this embodiment, the first sheet message section 213 is formed in an outline shape within the filled area 211, and the partition plate message section 313 is formed in a filled shape, but the reverse is also possible. A modified example of the first sheet specific area 200A according to this embodiment is shown in Figure 8, and a modified example of the partition plate specific area 300A according to this embodiment is shown in Figure 9. As shown in Figure 8, the first sheet specific area 210A in the first sheet pattern 200 of the first sheet 110 has an outline that is roughly cloud-shaped, and the area inside the outline is provided as the first sheet unfilled area 212A, which is an unfilled area. The first sheet message section 213A is formed in a filled shape within the first sheet unfilled area 212A.

[0044] On the other hand, as shown in Figure 9, the partition plate specific area 310A in the partition plate pattern 300 of the partition plate 130 is formed in a roughly cloud shape, with a black-filled area 311A ​​provided inside. The partition plate message area 313A is formed in an outline shape within the filled area 311A. If the outline of the first sheet specific area 210A is formed to be slightly smaller than the outer outline of the partition plate specific area 310A, the two can be superimposed without any sense of incongruity.

[0045] The first sheet's designated area 210A and the partition plate's designated area 310A are colored in a similar color, which is black. The first sheet's message section 213A is positioned to overlap with the filled-in area 311A ​​in the partition plate's designated area 310A. Therefore, in the non-storage state, the first sheet's message section 213A, consisting of the words and symbols "Look!", is made invisible by overlapping with the filled-in area 311A ​​of the partition plate's designated area 310A. Invisibility includes cases where it cannot be seen at all, as well as cases where it becomes difficult or impossible to see depending on the viewing angle, perspective, lighting conditions, etc. The partition plate's message section 313A, consisting of the words "You took it out properly" in white lettering, is exposed from the first sheet's unfilled area 212A in the first sheet's designated area 210A and is made visible. On the other hand, in the storage state, the partition plate specific area 310A is obscured by the stored documents, so the first sheet message section 213A overlaps with the stored documents and becomes visible.

[0046] The document storage bag 1 described above comprises a first sheet 110 and a second sheet 120, both formed transparent and arranged opposite each other in the thickness direction X; a partition plate 130 positioned between the first sheet 110 and the second sheet 120; a connecting portion 140 connecting the first sheet 110 and the second sheet 120; and an opening / closing connecting portion 150 that connects the first sheet 110 and the second sheet 120 so as to be openable and closable. The first sheet 110 is provided with a first sheet pattern 200 consisting of a predetermined design, and the partition plate 130 is provided with a partition plate pattern 300 consisting of a predetermined design different from the first sheet pattern 200.

[0047] As a result, the document storage bag 1 can store documents in the space between the first sheet 110 and the divider plate 130, and in the space between the second sheet 120 and the divider plate 130. When there are no documents stored between the first sheet 110 and the divider plate 130, the first sheet design 200 and the divider plate design 300 can be seen from the outside of the document storage bag 1, and when there are no documents stored between the first sheet 110 and the divider plate 130, only the first sheet design 200 can be seen. Therefore, for example, a child receiving printouts from school can enjoy the changing design as the printouts are put in and taken out, thus reducing the likelihood of forgetting to put in or take out documents. The document storage bag 1 also helps children to develop the habit of remembering to put in and take out documents. In other words, the interest and curiosity of the changing design encourages children, who are the main users of the document storage bag 1, to spontaneously put in and take out documents. Therefore, by using document storage bag 1, it is possible to establish a habit of putting documents in and taking them out, and to reduce instances of forgetting to put documents in or take them out.

[0048] Furthermore, the divider plate 130 is formed to be opaque. As a result, the back side of the divider plate 130 (the other side in the thickness direction X) is shielded, so that when no documents are stored inside, the divider plate design 300 can be clearly seen from the outside of the document storage bag 1.

[0049] Furthermore, the first sheet design 200 and the divider plate design 300 are positioned to overlap each other. As a result, the design visible in the same position within the document storage bag 1 changes, allowing children to enjoy the changes in the design even more.

[0050] Furthermore, the first sheet pattern 200 has first sheet specific areas 210, 210A, and the partition plate pattern 300 has partition plate specific areas 310, 310A positioned to overlap the first sheet specific areas 210, 210A, and the first sheet specific areas 210, 210A include first sheet message sections 213, 213A having at least one of characters, figures, or symbols, and the partition plate specific areas 310, 310A include partition plate message sections 313, 313A having at least one of characters, figures, or symbols, and the partition plate specific areas 310, 310A are provided with filled areas 311, 311A, and the first sheet specific areas 210, 210A are provided with first sheet unfilled areas 212, 212A which are unfilled areas, and the partition plate message section 313A is, The first sheet message section 213A is formed in a contour shape in the filled area 311A, and the first sheet message section 213A is formed in a filled shape in the first sheet unfilled area 212A, which is the unfilled area. The first sheet specific areas 210, 210A and the partition plate specific areas 310, 310A are colored in the same color. The first sheet message sections 213, 213A and the partition plate message sections 313, 313A are positioned so as not to overlap with each other. The first sheet message sections 213, 213A are positioned so as to overlap with the filled areas 311, 311A ​​in the partition plate specific areas 310, 310A, and the partition plate message sections 313, 313A are positioned so as to overlap with the first sheet unfilled areas 212, 212A, which are the unfilled areas in the first sheet specific areas 210, 210A. Furthermore, the partition plate specific area 310 is further provided with an unfilled partition plate unfilled area 312, and the first sheet specific area 210 is further provided with a filled area 211. Instead of the partition plate message area 313 being formed in an outline shape in the filled area 311A, it is formed in a filled shape in the unfilled partition plate unfilled area 312, and instead of the first sheet message area 213 being formed in a filled shape in the unfilled first sheet unfilled area 212A, it is formed in an outline shape in the filled area 211.As a result, when the document storage bag 1 is not in the storage state, the first sheet message sections 213, 213A overlap with the filled-in areas 311, 311A ​​of the partition plate specific areas 310, 310A, making them invisible. At this time, the partition plate message sections 313, 313A are exposed from the unfilled areas 212, 212A of the first sheet and become visible. When the document is in the storage state, the partition plate specific areas 310, 310A are obscured by the stored documents, and the first sheet message sections 213, 213A overlap with the stored documents and become visible. In this way, children can see the message in both the stored and unstored states, allowing them to enjoy taking documents in and out.

[0051] Furthermore, the partition message section 313 and the first sheet message section 213 are formed with corresponding messages. For example, the first sheet message section 213 can be set to the message "Look at this" and the partition message section 313 to "Well done." This allows for the creation of messages that correspond to the insertion and removal of documents from the document storage bag 1.

[0052] Furthermore, in the non-storage state, when no documents (print P1) are present between the first sheet 110 and the divider plate 130, the divider plate message portion 313 is exposed from the uncolored portion 212 of the first sheet, and the first sheet message portion 213 overlaps with the colored portion 311 in the specific area 310 of the divider plate. In the storage state, when documents (print P1) are present between the first sheet 110 and the divider plate 130, the divider plate pattern 300 is obscured by the documents (print P1), the divider plate message portion 313 is not exposed from the uncolored portion 212 of the first sheet, and the first sheet message portion 213 overlaps with the documents (print P1). As a result, in the non-storage state, the divider plate message portion 313 is visible, while the first sheet message portion 213 is not visible. Furthermore, when documents are stored, the partition message section 313 is obscured by the stored documents and cannot be seen, while the first sheet message section 213 can be made visible by overlapping it with the stored documents.

[0053] Furthermore, the first sheet 110 is textured, the first sheet pattern 200 is colored in the same color family as the partition plate pattern 300, and the first sheet pattern 200 is formed with a lower density than the partition plate pattern 300. As a result, even though the resin sheet 100, including the first sheet 110, is textured to reduce its transmittance in order to prevent the flexible resin sheet 100 from adhering too closely to laminated textbooks, etc., and making it difficult to remove the document storage bag 1 from, for example, a school bag, the partition plate pattern 300 and the first sheet pattern 200 are visible with the same density. Therefore, the partition plate pattern 300 and the first sheet pattern 200 can be seen from the outside without any sense of incongruity.

[0054] Furthermore, the connecting portion 140 includes a folded portion 141 which is formed by folding a single resin sheet to arrange the first sheet 110 and the second sheet 120 opposite each other in the thickness direction X. The folded portion 141 is the short side 101b of the first sheet 110 and the second sheet 120, which are each formed in an elongated rectangular shape. As a result, when the document storage bag 1 is stored in a school bag, the long sides 102a and 102b of the document storage bag 1 are folded. However, the folded portion 141 formed by folding the resin sheet 100 may be damaged if it is folded in a direction that intersects the fold line 141a (see Figure 4). However, in this embodiment, since the folded portion 141 of the document storage bag 1 is positioned on the short side 101b, the folded portion 141 will not be bent even when the document storage bag 1 is stored vertically in a school bag, and damage to the folded portion 141 when the document storage bag 1 is stored in a school bag can be suppressed.

[0055] Furthermore, the divider plate 130 is made of a resin plate that is harder than the resin sheet 100 and is formed in a rectangular shape that is smaller than the first sheet 110 and the second sheet 120. As a result, even if the top of the document storage bag 1 stored in the school bag is folded, the divider plate 130 can protect the printed materials from being folded.

[0056] Furthermore, the first sheet 110 and the second sheet 120 have a curved corner portion 105 that extends from one short side 101a (end 112) in the long side direction Z to one long side 102a (end 113) in the short side direction Y, and the opening / closing connection portion 150 is provided including the curved corner portion 105, and the connection portion 140 includes a wrapping connection portion 142 which is formed by sandwiching and sewing together the ends 111 and 121 of the other long side 102b of the first sheet 110 and the second sheet 120 with a fabric-like member 142a. Furthermore, the encasing connection portion 142 has a partition plate fixing portion 142b which is sewn together with a partition plate 130 sandwiched between the first sheet 110 and the second sheet 120. The end portion 132 of the short side on one side in the long side direction Z of the partition plate 130 is spaced apart from the ends 112, 121 of the short sides on one side in the long side direction Z of the first sheet 110 and the second sheet 120, so that the first sheet 110 and the second sheet 120 can be bent via the end portion 132 of the short side on one side in the long side direction Z of the partition plate 130. As a result, when the document storage bag 1 is stored in the school bag with the curved corner portion 105 facing upwards, even if the inner surface of the lid of the school bag and the upper side of the document storage bag 1 interfere with each other, the bag will be folded above the end portion 132 of the partition plate 130. Therefore, the documents stored in the document storage bag 1 are prevented from being folded.

[0057] The document storage bag 1 is formed by folding a single transparent resin sheet 100 with a surface treatment that reduces adhesion, arranging them opposite each other in the thickness direction X, with the folded portion 141 being the short side 101b, and the corners extending from the short side 101a on one side opposite the folded portion 141 in the long side direction Z to the long side 102a on one side in the short side direction Y being curved corners 105, and the document storage bag 1 is formed by a first sheet 110 and a second sheet 120 made of a resin plate that is harder and more opaque than the resin sheet 100, with the end 131 of the other long side in the short side direction Y being fixed together with the first sheet 110 and the second sheet 120, and the ends 132 and 133 of the short sides on one and the other sides in the long side direction Z being the short sides 101a and 10 The sheet comprises a partition plate 130 positioned at a distance from the ends 112, 122, and 107 of 1b, and an opening / closing connecting part 150 that connects the first sheet 110 and the second sheet 120 so as to be openable and closable, with a curved corner portion 105 extending from the short side 101a on one side in the long side direction Z to the long side 102a on one side in the short side direction Y. The first sheet 110 is provided with a first sheet pattern 200 consisting of a predetermined design, and the partition plate 130 is provided with a partition plate pattern 300 consisting of a predetermined design different from the first sheet pattern 200. The first sheet pattern 200 and the partition plate pattern 300 are positioned to overlap each other, the first sheet pattern 200 is colored in the same color as the partition plate pattern 300, and the first sheet pattern 200 is formed with a lower density than the partition plate pattern 300. As a result, the document storage bag 1 is easy for children and others to use, and helps prevent them from forgetting to put documents in or take them out.

[0058] Furthermore, the document storage bag according to the embodiment of the present invention described above is not limited to the embodiment described above, and various modifications are possible within the scope described in the claims for utility model registration.

[0059] In the above description, the first sheet design 200 and the partition plate design 300 are positioned to overlap each other, but they may be positioned so that all or part of them do not overlap. Also, the first sheet message section 213 and the partition plate message section 313 are composed of text, but are not limited to this and may be composed of figures, symbols, etc. Also, the first sheet design 200 and the partition plate design 300 may be colored in a color other than black (for example, brown). Also, the connecting section 140 is formed as a folded section 141 or a wrapping connecting section 142, but other configurations are acceptable as long as the first sheet 110 and the second sheet 120 are connected. Also, the opening and closing connecting section 150 may be in a form other than a zipper, as long as it allows stored documents to be inserted and removed.

[0060] The document storage bag according to this embodiment may be constructed by appropriately combining the components of the embodiments and modifications described above. [Explanation of Symbols]
