  The conventional document storage box is basically used in a state where the storage space is opened upward, and has poor browsing properties (see, for example, Patent Document 2). In addition, in this type, when the other document storage box is stacked on one document storage box and used, the other document storage box having a considerable weight is used as one document storage box. After moving from the top of the storage box, it is necessary to open the top cover of one document storage box and check the contents.

  Under such circumstances, a document storage box has been conceived in which the front side of the storage space is opened to ensure readability (see, for example, Patent Document 1 below).

  However, although such a document storage box has a certain browsing property, it has not been assumed that another text storage box is stacked thereon.

  In order to solve this disadvantage, it is possible to reinforce the wall of the document storage box with a separate member from the document storage box to ensure the vertical strength, but the assembly work becomes complicated or separation at the time of disposal The work can be laborious.

  By the way, what has arrange | positioned the partition which makes the planar view H shape in storage space is also considered (for example, refer the following patent document 2). This partition is assumed to be used in a state where the storage space is opened upward, and as described above, a state in which the storage space is opened forward by stacking a plurality of document storage boxes in the vertical direction, In other words, it is not assumed that the partition is used upright. Therefore, when the document storage box is used upright, there is a problem that the partition cannot properly receive the overload.

From this state, as shown in FIG. 13, the two inner folding lines L <b> 21 and L <b> 22 are bent to form the partition main body 7 composed of the left and right partition plates 71 and 73 and the small edge plate 72. In this state, as shown in FIG. 14, the partition B <b> 2 in which the reinforcing structures 8 that make a pair on the left and right of the partition main body 7 are located is completed.

  The completed partition B2 is inserted into the box body B1 during the assembly of the box body B1. That is, the box body B1 is formed by folding the unfolded sheet body B3 shown in FIG. 15 and the inner folding lines L1, L2, L3, and L6, respectively, as shown in FIGS. 31, the top plate 21 and the other outer plate 41 are formed in a cylindrical shape, and the connection piece 111 is bonded to the inner surface of the other outer plate 41.

  The back wall 5 is assembled from this state. That is, first, as shown in FIG. 18, the upper back plate 52 is placed in a hanging position by bending the inner folding line L13, and the left and right side rear plates 53 and 54 are folded inward as shown in FIG. , Bent inward via L16 and overlapped on the back side of the upper back plate 52. Thereafter, as shown in FIG. 20, the lower back plate 51 is folded upward through the inner folding line L5. Then, the insertion piece 511 provided at the tip is inserted into a slit 58 formed by the upper back plate 52 and the left and right side back plates 53 and 54 to complete the main part of the back wall 5.

  In this state, partition receiving portions 56 and 57 are formed on the inner surface of the back wall 5. That is, a groove-shaped partition receiving portion 56 is formed between the front ends of the left and right side rear plates 53, 54, and a notch-shaped partition receiving portion 57 formed in the center of the insertion piece 511 is in the storage space S. Will come.

  The partition B2 is inserted into the box body B1 thus assembled as shown in FIG. The rear end portion of the partition main body 7 inserted to the final position is engaged with the partition receiving portions 56 and 57 and is positioned in the left-right direction.

  After that, as shown in FIGS. 22 and 23, the left and right inner plates 32, 42 are folded inward through the two inner folding lines L7, L8, L14, L15 to complete the left and right side walls 3, 4. At this stage, the left and right first and second side reinforcing plates 82, 85, 87, 88 of the reinforcing structure 8 of the partition B2 are incorporated in the left and right side walls 3, 4. That is, the first and second side reinforcing plates 82, 85, 87, 88 are interposed between the outer plates 31, 41 and the inner plates 32, 42. Is made. In addition, outer folding lines L17 and L18 are formed in the front-rear direction intermediate portion of the left and right inner plates 32 and 42, and the left and right inner plates 32 and 42 and the left and right extending pieces 34 and 44 are connected. Between the outer folding lines L33, L34 are formed, and as shown in FIGS. 22 and 23, the outer folding lines L33, L34 are incorporated while being folded in two through the outer folding lines L17, L18, L33, L34. At this time, the left and right extending pieces 34 and 44 come into contact with the front surfaces of the lower half portions 531 and 541 of the left and right side rear plates 53 and 54 to constitute the back wall 5.

  Next, as shown in FIG. 24, the left and right inner bottom plates 12 are folded inward via an inner folding line L4 to complete the bottom wall 1. In addition, outer folding lines L19 and L20 are formed in the middle part in the front-rear direction of the left and right inner bottom plates 12. The folding lines L19 and L20 are assembled while being folded in two. At this stage, the bottom reinforcing plates 81 and 84 of the reinforcing structure 8 of the partition B2 are incorporated into the bottom wall 1 and hidden.

  The order of the operation of folding the left and right inner bottom plates 12 inward and the operation of folding the left and right inner plates 32 and 42 inward may be reversed.

  The document storage box B assembled in this way is used as a shelf with the lid 6 held in the open position (O), and as a storage box with the lid 6 held in the closed position (C). It may be used.

  First, a method of using the lid 6 in a state where the lid 6 is held in the open position (O) will be described.

  In this case, as shown in FIG. 25, the lid body 61 of the lid 6 is rotated to a position overlapping the top plate 21 of the box body B1 via the hinge 23. At that time, the adjustment plate 62 and the shape retaining plate 64 are bent with respect to the lid main body 61 to a position orthogonal to the lid main body 61 via the outer folding line L11. Are inserted into a pocket 55 formed between the upper back plate 52 and the left and right side back plates 53, 54. In this way, as shown in FIG. 2, the document storage box B with the storage space S opened forward can be used as a single unit, and a plurality of such document storage boxes B can be used as shown in FIG. They can be stacked and used on a shelf.

  In the case of stacking a plurality, the cut and raised pieces 22 of the top plate 21 are cut and raised as shown in FIG. 26 before bringing the lid 6 to the open position (O). When the lid 6 is rotated to the closed position (C), the cut and raised piece 22 on the rear edge side is inserted into the slit 65 provided on the rear edge of the lid body 61 as shown in FIGS. Then, the left and right cut and raised pieces 22 are positioned outside the both side edges of the lid body 61 and protrude upward.

  In this state, another document storage box B having the same structure is stacked on the top plate 21 and the lid body 61. At that time, as shown in FIGS. 29 and 30, the cut and raised pieces 22 are inserted into the slits 14 and 15 provided in the bottom wall 1 of the other document storage box B, respectively. As a result, misalignment between the document storage box B and another document storage box B is prevented. As described above, a plurality of document storage boxes B can be used as shelves that can accommodate files and the like so as to be detachable without causing positional displacement.

  On the other hand, when used as a storage box, as shown in FIG. 3, the lid 6 is brought to the closed position (C), and the storage space S is closed by the lid body 61 and the adjustment plate 62. In this case, the shape-retaining plate 64 is folded and used so as to be attached to the inner surface side of the adjustment plate 62 and the lid body 61 via the inner folding line L12.

  More specifically, the cut and raised piece 641 of the shape retaining plate 64 is cut and raised through the inner folding line L31, and the shape retaining plate 64 is folded back to the inner surface side of the adjustment plate 62 and the lid body 61. At that time, the cut and raised piece 641 is passed through the slit 65 provided at the boundary between the lid main body 61 and the adjustment plate 62 from the inside, and the base end slit 642 is externally fitted to the protruding portion 651 and communicated with the recessed portion 652. The shape retaining plate 64 is held in the folded position by fitting the portion 643 therein. As a result, the lid body 61 and the adjustment plate 62 are held substantially flush with each other by the function of the shape retaining plate 64. Further, since the cut and raised piece 641 protrudes to the front side of the lid main body 61, the cut and raised piece 641 can be used as a handle for opening and closing the lid 6. The insertion piece 63 is used to hold the lid 6 in the closed position (C) while being cut and raised from the shape retaining plate 64. That is, the lid 6 is held in the closed position (C) by closely engaging the notch 631 of the insertion piece 63 with the partition body 7.

  As described above, the document storage box B according to the present embodiment includes the storage space S in which both side edges of the bottom wall 1 and the top wall 2 are connected to each other by the side walls 3 and 4 and are opened at least forward. A box body B1 provided, and a partition B2 arranged in the storage space S of the box body B1, wherein the partition B2 is made of the same material as the box body B1, and the storage space A partition body 7 that divides S into left and right sides, and a reinforcing structure 8 that is connected to the partition body 7 and reinforces the box body B1. The reinforcing structure 8 includes the box body First and second side reinforcing plates 82, 85, 87 which are attached to the side walls 3 and 4 of B1 and receive an overload acting on the top wall 2 of the box body B1 in cooperation with the side walls 3 and 4. 88.

  Since it has such a configuration, it is possible to secure the strength when accommodating documents used in the office or the like and using them as shelves without impairing the original functions. In other words, the cover 6 is put in a state in which documents and files that have entered the storage period are stored in the storage space S, and not only the original usage of storing in a warehouse or cabinet, but also a plurality of such storages instead of shelves. If the boxes B are stacked and placed, it can be used in an active state in which the storage space S is opened and used as a shelf for storing files or the like in the office or the like. Further, as other usage scenes of the document storage box B, for example, it is suitable for a place such as a project team or a construction site, not a permanent office, but a limited-time office / workplace, etc. After the construction is completed, the storage box B can be disposed of together with the box when the place is lifted after the construction is completed.

  That is, a conventional document storage box, for example, a so-called lid-type document storage box or a drawer-type document storage box that opens the storage space only upward, takes time and effort to put documents and files in and out of the storage space. Therefore, once it was stored in the storage space, the frequency of use was low. However, according to the present embodiment, the document storage box B can be simply placed in an empty space around a desk or the like to increase the use frequency. Of course, the document storage box B may not be provided with the lid 6 when the storage space S is used with the front surface opened.

  Since this document storage box B is made of only a single material, that is, cardboard, it is strong, lightweight, low in manufacturing cost, easy to disassemble and assemble, and can be separated when discarded. Work becomes unnecessary.

  In addition, since it is configured as described above, the strength is high despite the fact that it is composed only of corrugated cardboard, and it is convenient for use as a shelf. More specifically, the document storage box B exhibits a reinforcing effect with the partition body 7 of the partition B2 interposed between the bottom wall 1 and the top wall 2 of the box body B1. In addition, since the reinforcing structures 8 are provided on both sides of the partition B2, the possibility that the side walls 3, 4 and the partition B2 buckle and break even if a large load is applied to the top plate 21 can be reduced. . Specifically, the reinforcing structure 8 is attached to the side walls 3 and 4 of the box body B1 and receives an overload acting on the top wall 2 of the box body B1 in cooperation with the side walls 3 and 4. Since the first and second side reinforcing plates 82, 85, 87, 88 are provided, even when a large number of document storage boxes B are stacked and used, it is difficult to cause a problem of being deformed or broken.

  In particular, in this embodiment, the abutting portion of each plate, in particular, between the inner plates 32 and 42 and the bottom wall 1 and the top wall 2, between the partition body 7 and the bottom wall 1 and the top wall 2, side reinforcement. There are no gaps between the plates 82 and 85 and the bottom wall 1 and the top wall 2, and the members are assembled in close contact. For this reason, it is possible to disperse the loading load at various locations to exhibit high strength. Specifically, in the conventional one, there is a clearance at the part where the plates are engaged with each other to pursue ease of assembly, and the lower document storage box tends to collapse when stacked vertically with the storage space open. Even if there was a partition, it was easy to cause buckling of the partition. However, in the present embodiment, there is a portion that is in close contact with the whole in the vertical direction, so that it can withstand a certain amount of overload.

  Furthermore, since the cutout portion 124 is provided at a location where such an overload is not concentrated, the operation can be efficiently performed by placing a finger on the assembly and disassembly.

  The reinforcing structures 8 form a pair provided on both sides of the partition body 7, and each reinforcing structure 8 extends along the bottom wall 1, the side walls 3, 4 and the top wall 2 of the box body B1. Since it has a frame shape, the strength of the entire box can be increased.

  The box body B1 includes side walls 3 and 4 having a double wall structure including outer plates 31 and 41 and inner plates 32 and 42, and the first and second side reinforcing plates of the reinforcing structure 8. 82, 85, 87 and 88 are accommodated between the outer plates 31 and 41 and the inner plates 32 and 42. Therefore, the left and right side walls 3 and 4 of the box body B1 have a quadruple wall structure of the outer side plates 31 and 41, the inner side plates 32 and 42, and the first and second side reinforcing plates 82, 85, 87, and 88. The strength against buckling can be increased as compared with the above.

  The box body B1 includes a back wall 5 that closes the rear side of the storage space S, and the back wall 5 includes partition receiving portions 56 and 57 for positioning the partition body 7. Therefore, the left-right position shift of the partition main body 7 can be suppressed.

  The box body B1 has slits 14 and 15 on the bottom wall 1 and a cut and raised piece 22 on the top wall 2, and another document storage box having the same structure on the top wall 2 The cut and raised piece 22 is configured to engage with the slits 14 and 15 of the other document storage box B in a state where B is placed. Therefore, a plurality of document storage boxes B can be stacked in multiple stages without deviation, and the entire document storage boxes B after stacking can be stabilized. Even when a plurality of document storage boxes B are stacked, it is possible to easily and efficiently retrieve and store the stored contents such as documents, and to easily search the stored contents such as documents. The effect of becoming is also obtained.

  The box body B1 has a lid 6 connected to the front edge of the ceiling wall 2 via a hinge 23. The lid 6 covers the front surface of the storage space S and the ceiling position (C). Since it can be opened and closed with the open position (O) overlapping on the wall 2, it can be used not only when the lid 6 is closed but also when the lid 6 is opened and the storage space S is opened. can do.

  Since the lid 6 is configured to be able to open to the open position (O) without interfering with the cut and raised pieces 22 cut and raised from the top wall 2, the lid 6 is opened. However, a plurality of document storage boxes B can be stacked. In other words, the document storage box B of the present embodiment moves up and down the document storage box B having the same structure both in the state where the lid 6 is positioned in the open position (O) and in the state where it is positioned at the closed position (C). Can be stacked in the direction.

  In addition, since the document storage box B of the present embodiment has the hinge 23 positioned in front of the front edge of the box body B1, the document storage box B can be neatly overlapped with the top wall 2 in the open position (O). In addition, it is not restricted to what set the front-back direction width dimension of the top wall 2 larger than the front-back direction width dimension of the left-right side walls 3 and 4 like this embodiment, The front-back direction width dimension of the top wall 2 and left-right The side walls 3 and 4 may have the same or substantially the same width dimension in the front-rear direction. Of course, other dimensions may be used.

  Further, in the present embodiment, the lid holding pocket 55 of the back wall 5 has a taper at a trigger portion into which the tip end side of the lid 6 is inserted, so that the lid 6 can be easily inserted and extended inward. Since there is a bulging portion, it is possible to suppress the lid 6 from coming off naturally. That is, since the upper half portions 532 and 542 of the side rear plates 53 and 54 of the back wall 5 are inflated to the extent that the entrance (upper edge portion) of the pocket 55 does not hinder the insertion of the lid 6, the lid 6 is inserted. A structure that is easy but difficult to come off can be obtained.

  Further, the document storage box B of the present embodiment is not a cube having the same length of all sides, but is specifically a vertically long rectangular parallelepiped of 343 mm long × 329 mm wide × 298 mm deep. Not only is it easy, but the overall strength of the box can be increased.
