Description

[Technical Field]

[0001] The present invention relates to a document storage device. [Background technology]

[0002] If a child places handouts distributed at elementary school directly into their school bag or desk, the handouts may become bent or torn. For example, if the handouts are placed in a clear file and stored in the school bag or desk, damage to the handouts can be prevented. However, with the increase in the number of pages in textbooks and the distribution of tablet devices in recent years, there is less space in school bags and desks. If multiple clear files are crammed into this limited space, the handouts may become bent along with the clear file, and it may be difficult to remove the desired clear file from the school bag or desk.

[0003] For example, Patent Document 1 below shows a document storage device that has a holder for storing documents inside and a holder case for storing multiple holders. In this way, if multiple holders containing documents are stored in the holder case and stored in a backpack or desk, damage to the documents and holders can be prevented.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-88483 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the document storage device of Patent Document 1 has openings on the long sides of the holder and the holder case, and a lid for opening and closing the openings. If such a document storage device is stored in a school bag or a desk, when taking out a document, it is necessary to first take out the entire holder case from the school bag or the desk, then open the lid of the holder case to take out the holder, and then open the lid of the holder again to take out the document, which is very time-consuming.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a document storage device that allows documents to be easily taken in and out while stored in a backpack, desk, or the like. [Means for solving the problem]

[0007] The inventors of the present invention have been particularly focused on the purpose of making it possible to easily take documents in and out while the documents are stored in a backpack or the like, and have come up with the idea of ​​a document storage device with the following features. (1) Make the case thinner. (2) One end of the case in the vertical direction (long side direction of the documents) is opened, allowing the file to be removed vertically from the case. (3) Do not place a lid on the opening of the case; keep it open at all times.

[0008] Specifically, the present invention provides a document storage device including a plurality of files having substantially rectangular front and rear sheets for storing documents sandwiched between the front and rear sheets, and a case for storing the plurality of files therein, the case has substantially rectangular front and rear surfaces opposed to each other in a thickness direction, a pair of side surfaces connecting a pair of long sides of the front surface and a pair of long sides of the rear surface, a bottom surface connected to one short side of the front surface, one short side of the rear surface, and one short side of the pair of side surfaces, and an opening formed by the other short side of the front surface, the other short side of the rear surface, and the other short side of the pair of side surfaces; The opening is open without being covered by another member, The document storage device has a ratio D / W of the thickness dimension D of the case to the short side dimension W of the front and rear portions of 0.1 or less.

[0009] Normally, documents are inserted and removed from a school bag or desk vertically (the long side of the document). Therefore, by making the case thin so that it can be stored in the limited space inside a school bag or the like, and by providing an opening at one vertical end of the case, which is formed by the front, rear, and the other short side of the pair of side portions, and by keeping this opening open at all times without covering it with a lid or other member, files can be easily inserted and removed from the case while the case is stored inside the school bag or desk.

[0010] When inserting a file through the opening of a case, if the file is inserted at an angle relative to the case, the file may get caught in the opening and be difficult to insert. Therefore, it is preferable to position the other short side of the pair of side sections (the short side closer to the opening) closer to the bottom than the other short sides of the front and rear sections (the short sides closer to the opening). This creates a recess between the front and rear sections on the opening side of the case. Fitting the file into this recess guides the file, and correcting the file's angle relative to the case in this state makes it easier to insert the file into the case.

[0011] The file may have a configuration in which the front sheet and the rear sheet are connected at one long side and one short side, and separated at the other long side and the other short side. In this case, it is preferable to provide a protruding portion at the widthwise middle of the other short side (the short side not fixed to the rear sheet) of the file, protruding further away from the one short side than the setbacks provided at both widthwise ends. When a document is sandwiched between the front sheet and the rear sheet of this file, the widthwise region of the front sheet where the protruding portion is located can hold the entire length of the document. Furthermore, since a portion of the document is exposed through the setback portion of the front sheet, the document can be easily removed by grasping this portion. In particular, providing setbacks on both sides of the protruding portion allows the document to be removed from either setback.

[0012] When a file is already stored in a case and another file is inserted through the opening, the file already inside the case can get in the way, making it difficult to insert the other file. Therefore, it is preferable to provide a notch on the edge of the other short side (the short side closest to the opening) of the front of the case so that, when a file is stored inside the case, the notch and the protruding portion of the file overlap in the thickness direction. In this case, a portion of the front sheet (protruding portion) of the file already stored in the case is exposed from the notch on the front side (front side) of the case in the thickness direction. Therefore, the other file can be easily inserted into the case by pushing the protruding portion of the file inside the case toward the rear side through the notch on the front side of the case.

[0013] If the file material is made thinner and less rigid, the front sheet becomes easier to flip, making it easier to insert and remove documents from the file, but the entire file easily deforms, making it difficult to insert files through the opening of the case. On the other hand, if the file material is made thicker and more rigid, the opposite occurs: it becomes easier to insert files through the opening of the case, but it becomes more difficult to insert and remove documents from the file. Therefore, it is preferable to make the rear sheet of the file thicker than the front sheet. In this way, by making the rear sheet thicker, the rigidity of the entire file is ensured, making it easier to insert files through the opening of the case. Furthermore, by making the front sheet thinner, the front sheet becomes easier to flip, making it easier to insert and remove documents from the file. [Effects of the Invention]

[0014] As described above, the document storage device of the present invention allows documents to be easily taken in and out while stored in a backpack, desk, or the like. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0017] As shown in Figures 1 to 3, a document storage device according to one embodiment of the present invention has a case 1 and a plurality of files 2 (three in the illustrated example) housed inside the case 1. The file 2 is adapted to hold, for example, A4-sized documents P and has a generally rectangular shape that is slightly larger than the A4-sized documents P when viewed in the thickness direction (see Figure 7). The case 1 is a vertical case that has a generally rectangular parallelepiped shape that can house the files 2 inside and is open on one of the long sides of the files 2 (see Figure 4).

[0018] In the following explanation, when a file 2 is stored inside the case 1, the long side direction of the file 2 is referred to as the "vertical direction" (the up-down direction in Fig. 2), the short side direction as the "width direction" (the left-right direction in Fig. 2), and the direction perpendicular to these as the "thickness direction" (the left-right direction in Fig. 3). Also, for the sake of convenience, the opening side of the case 1 in the vertical direction will be referred to as the "upper side" (the upper side in Fig. 2) and the opposite side as the "lower side" (the lower side in Fig. 2), but this is not intended to limit the manner in which the document storage device can be used.

[0019] As shown in FIG. 4, the case 1 has a front portion 11, a rear portion 12, a pair of side portions 13, and a bottom portion 14. The front portion 11 and the rear portion 12 are vertically elongated, approximately rectangular, and face each other in the thickness direction. One side portion 13 connects one long side of the front portion 11 to one long side of the rear portion 12, and the other side portion 13 connects the other long side of the front portion 11 to the other long side of the rear portion 12. The bottom portion 14 is connected to the lower short side of the front portion 11, the lower short side of the rear portion 12, and the lower short sides of the pair of side portions. The bottom end of the rectangular cylinder formed by the front portion 11, the rear portion 12, and the pair of side portions 13 is closed by the bottom portion 14. The case 1 is made of resin, such as polypropylene. If the case 1 is made of a transparent or translucent material, it becomes easier to see the files 2 and documents P stored inside.

[0020] 1 and 2, the case 1 may be provided with an insertion section 17 for inserting a card Q having a timetable or the like written thereon. For example, by fixing the top end, bottom end, and one end in the width direction of a thin transparent or translucent resin plate to the front portion 11 of the case 1, it is possible to form the insertion section 17 into which the card Q can be inserted and removed from the other end in the width direction.

[0021] An opening 15 is provided at the top end of the case 1 (see FIG. 4). The opening 15 is formed by the upper short side of the front surface 11, the upper short side of the rear surface 12, and the upper short sides of the pair of side surface portions 13. In the illustrated example, the entire upper short side of the front surface 11, the entire upper short side of the rear surface 12, and the entire upper short sides of the pair of side surface portions 13 face the opening 15. The case 1 does not have any other member, such as a lid, that covers the opening 15, and the opening 15 is always open.

[0022] The upper short sides of the pair of side surface portions 13 of the case 1 are disposed below the widthwise ends of the upper short sides of the front surface portion 11 and the rear surface portion 12. As a result, a recess 16 is formed above each side surface portion 13, sandwiched between the front surface portion 11 and the rear surface portion 12.

[0023] The thickness of the case 1 is smaller than its width. Specifically, the ratio D / W of the width W of the case 1 (see FIG. 2), i.e., the width W of the front and rear sections 11 and 12 to the thickness D of the case 1 (see FIG. 3), is 0.1 or less. As shown in FIG. 2, when multiple files 2 are stored inside the case 1, the width W of the entire document storage device (i.e., the width W of the case 1) and the length H are smaller than the width and length of the interior of a school bag and larger than the width and length of an A4-sized sheet of paper. The width W of the case 1 in this embodiment is 230 mm or less, and the thickness D is 15 mm or less.

[0024] By making the case 1 thinner in this way, the entire case 1 can be stored in a small space inside a school bag or a desk, as shown in Figures 18 and 19. Also, by providing an opening 15 at the top end (one vertical end) of the case 1 and leaving this opening 15 open at all times without being covered by any other member such as a lid, it is possible to easily take files 2 in and out of the case 1 while the case 1 is stored inside the school bag or a desk. Also, as shown in Figures 18 and 19, when the file 2 is partially pulled out from the case 1, documents P held in the file 2 can be taken out.

[0025] A concave cutout 11a is provided in the upper short side of the front surface 11 of the case 1 (see FIGS. 2 and 4). The cutout 11a is provided in the middle portion of the width direction of the upper short side of the front surface 11, and in the illustrated example, it is provided in the center portion of the width direction. The width direction dimension of the cutout 11a is, for example, 1 / 4 to 1 / 2 (approximately 1 / 3 in the illustrated example) of the width direction dimension W of the case 1. The cutout 11a in the illustrated example has a smoothly curved concave curve.

[0026] A long hole 12a is provided near the upper end of the rear surface 12 of the case 1 (see FIG. 4). The long hole 12a is a horizontally elongated hole whose width dimension is greater than its length dimension, and is provided, for example, in the center of the width direction near the upper end of the rear surface 12. The long hole 12a functions as a handle when holding the case 1. Of the upper short sides of the rear surface 12, a widthwise region that includes the widthwise region of the long hole 12a is provided with a protruding portion 12b that protrudes upward more than the linear portions 12c provided on both sides of the widthwise region. The linear portion 12c at the upper end of the rear surface 12 and the linear portion 11b at the upper end of the front surface 11 are located at the same height (vertical position).

[0027] The case 1 is formed, for example, from a single thin plate 1' as shown in FIG. 5. The thin plate 1' is made of a single flat resin sheet and integrally includes a front portion 11, a rear portion 12, a bottom portion 14, a pair of front side surface portions 13a provided on both sides of the front portion 11 in the width direction, and a pair of rear side surface portions 13b provided on both sides of the rear portion 12 in the width direction. As shown in FIG. 6, the boundaries of each portion of the thin plate 1' are folded, and the front side surface portions 13a and the rear side surface portions 13b are overlapped and welded to form the case 1 shown in FIG. 4. Note that the manufacturing method of the case 1 is not limited to the above, and for example, the case 1 may be formed using a plurality of thin resin plates.

[0028] As shown in Fig. 7, the file 2 has a front sheet 21 and a back sheet 22 each having a vertically elongated, generally rectangular shape. The front sheet 21 and the back sheet 22 of the file 2 are connected at one long side 2a (left side in the figure) and the lower short side 2b, and are separated at the other long side 2c (right side in the figure) and the upper short side 2d. This allows the front sheet 21 of the file 2 to be turned forward at the upper right corner in the figure, as shown in Fig. 8.

[0029] A protruding portion 21a is provided in the widthwise middle portion of the upper short side of the front sheet 21 of the file 2. The protruding portion 21a protrudes upward more than the recessed portions 21b provided at both widthwise ends. In the illustrated example, the protruding portion 21a is provided in the widthwise center portion of the upper short side of the front sheet 21. In the illustrated example, the widthwise center portion of the protruding portion 21a forms a smoothly curved convex curve. Both widthwise ends of the protruding portion 21a form a smoothly curved concave curve that continues smoothly with the recessed portions 21b.

[0030] When an A4-sized document P is sandwiched and stored in the file 2, the upper end of the document P is located below the protruding portion 21a of the front sheet 21, so the center of the upper end of the document P in the width direction is held down by the protruding portion 21a of the front sheet 21. This allows the upper end of the document P to be held without tipping forward. Furthermore, because the upper end of the document P stored in the file 2 is located above the recessed portion 21b of the front sheet 21, the vicinity of the corner of the upper end of the document P is exposed on the front side (the front side of the page). This allows the document P to be easily removed from the file 2 by pinching the corner of the upper end of the document P exposed on the front side. In particular, in the illustrated example, the recessed portions 21b are provided on both ends of the width direction of the front sheet 21, so either the left or right corner of the upper end of the document P can be pinched, making it easier to remove the document P from the file 2.

[0031] A notch 21c is provided in the other long side (right side in FIG. 7) of the front sheet 21 of the file 2. The notch 21c is provided in the vertical middle portion of the other long side of the front sheet 21, and in the illustrated example, it is provided in the vertical center portion. The vertical dimension of the notch 21c is, for example, 1 / 4 to 1 / 2 (approximately 1 / 3 in the illustrated example) of the vertical dimension of the other long side of the front sheet 21. The notch 21c in the illustrated example has a smoothly curved concave curve. As shown in FIG. 8, by holding a document P with a finger through the notch 21c in the front sheet 21 and flipping the front sheet 21 towards you, it becomes easier to remove the document P from the file 2.

[0032] The upper short side of the rear sheet 22 of the file 2 is provided with a tab 22a that protrudes upward relative to other areas. As shown in Figures 1 and 2, when the file 2 is housed inside the case 1, the tab 22a protrudes upward from the opening 15 of the case 1. In the illustrated example, the tab 22a is located above the upper end of the case 1, particularly above the straight portions 11b and 12c located at both widthwise ends of the upper ends of the front and rear portions 11 and 12. The rest of the file 2 other than the tab 22a is located below the straight portions 11b and 12c of the case 1. The tabs 22a of each file 2 are offset in the width direction.

[0033] 2, when the file 2 is housed inside the case 1, the notch 11a in the front portion 11 of the case 1 and the protruding portion 21a in the front sheet 21 of the file 2 overlap in the thickness direction. In other words, the protruding portion 21a of the front sheet 21 of the file 2 inside the case 1 is exposed to the front side (the front side of the paper) through the notch 11a in the front portion 11 of the case 1.

[0034] When inserting another file 2 through the opening 15 of the case 1 while the file 2 is stored in the case 1, as shown in FIG. 9, the lower corner of the other file 2 pushes the protruding portion 21a of the front sheet 21 of the file 2 in the case 1 backward (toward the back of the page) through the notch 11a in the front surface 11 of the case 1. This ensures space within the case 1 for inserting the other file 2. When the other file 2 is inserted into the case 1 in this state, as shown in FIG. 10, the lower short side of the other file 2 abuts against the upper end of the side surface 13 of the case 1 (the bottom of the recess 16). At this time, because the front surface 11 and the rear surface 12 extend upward beyond the upper end of the side surface 13, the file 2 abutting against the upper end of the side surface 13 is positioned between the front surface 11 and the rear surface 12 and guided in the thickness direction.

[0035] In this state, adjust the orientation of the file 2 relative to the case 1 so that the long side direction of the file 2 coincides with the long side direction of the case 1, and fit the lower end of the file 2 between the pair of side surface portions 13 of the case 1 (see FIG. 11). Then, lower the file 2 and store it inside the case 1 (see FIG. 1).

[0036] In this way, in this embodiment, the file 2 can be easily inserted through the opening 15 of the case 1 by utilizing the notch 11a provided in the front portion 11 of the case 1 and the recess 16 provided above the side portion 13.

[0037] In this embodiment, the front sheet 21 and the rear sheet 22 of the file 2 are formed from different resin sheets. In this embodiment, each file 2 is formed by combining the front sheet 21 shown in FIG. 12 with any of the rear sheets 22 shown in FIG. 13. The front sheet 21 and the rear sheet 22 are formed from a resin, for example, polypropylene. The front sheet 21 may be transparent or semi-transparent so that the documents P inside can be seen. The rear sheet 22 is, for example, opaque.

[0038] The rear sheet 22 is thicker than the front sheet 21. For example, the front sheet 21 is less than 0.3 mm thick (for example, about 0.2 mm), and the rear sheet 22 is 0.3 mm or more thick (for example, about 0.4 mm). By making the front sheet 21 thinner in this way, the front sheet 21 becomes more easily deformed, making it easier to turn over toward the front as shown in FIG. 8. On the other hand, by making the rear sheet 22 thicker, the rigidity of the entire file 2 is increased, making it less likely to deform, making it easier to insert into the case 1.

[0039] As shown in FIG. 12, before being secured to the rear sheet 22, the front sheet 21 has a substantially rectangular main body 21d with a protruding portion 21a, a recessed portion 21b, and a notch 21c, a protruding portion 21e on one widthwise side (left side in the figure) of the main body 21d, and a protruding portion 21f on the lower side of the main body 21d. Fold-back lines 21g and 21h are provided at the boundaries between the main body 21d and the protruding portions 21e and 21f. As shown in FIG. 13, the rear sheet 22 has a substantially rectangular main body 22b, a tab 22a protruding upward from the top end of the main body 22b, and a tab 22c protruding outward in the widthwise direction from the top end of the long side of the main body 22b on one widthwise side (left side in the figure). Note that FIG. 13 shows the rear sheet 22 of a file 2 in which the tab 22a is provided at the end on one widthwise side. The rear sheet 22 of the other file 2 has the same structure as that shown in FIG. 13 except for the position of the index portion 22a in the width direction.

[0040] When the front sheet 21 of FIG. 12 and the back sheet 22 of FIG. 13 are stacked and turned over, the protruding portions 21e and 21f of the front sheet 21 protrude from the back sheet 22, as shown in FIG. 14. In this state, the vertical fold line 21g is located widthwise outward of the long side 22d of the main body 22b of the back sheet 22 and is located at the same widthwise position (on the same straight line) as the widthwise outer end of the protruding portion 22c of the back sheet 22. Furthermore, the widthwise fold line 21h is located below the lower short side 22e of the main body 22b of the back sheet 22. In this state, the front sheet 21 is folded back at the fold lines 21g and 21h to place the protruding portions 21e and 21f on the back side of the back sheet 22 and weld the protruding portions 21e and 21f to the back sheet 22, thereby completing the file 2 (see FIG. 15). As a result, one long side 2a of the file 2 in the width direction is formed by the fold line 21g of the front sheet 21, and the lower short side 2b of the file 2 is formed by the fold line 21h of the front sheet 21.

[0041] For example, as shown in Fig. 16, when the ends of the front sheet 21 and the rear sheet 22 are overlapped and welded together, the space between the two sheets 21, 22 becomes very narrow near the ends, making it difficult to insert a document P all the way to the ends. In contrast, in this embodiment, as shown in Fig. 17, the ends 2a, 2b of the file 2 (the lower short side 2b is shown in Fig. 17) are formed by fold lines 21g, 21h of the front sheet 21. In this case, by increasing the folding angle at the fold lines 21g, 21h, the internal space near the ends 2a, 2b of the file 2 (the gap between the front sheet 21 and the rear sheet 22) can be expanded, making it easier to insert a document P all the way to the ends of the file 2.
