  As shown in FIGS. 3 and 4, the third convex portion 33 is formed in each of the divided regions 2 b and 2 d where the second convex portion 32 is formed. Moreover, the 3rd convex part 33 is formed in the shape (for example, planar view belt shape) which can be engaged with the inner wall of the 1st convex part 31 in the other storage container 1 of the same kind in the 2nd abutting state. . The third convex portion 33 is in a direction along the sides 32a and 32a of the second convex portion 32 in this second abutting state (in this example, the longitudinal direction of the storage container 1 and the horizontal direction in FIG. 4). The relative movement of each storage container 1 is regulated.

  As shown in FIGS. 1 and 2, a rib 6 is formed inside the bottom portion 2, and partition portions 7 a, 7 a. Moreover, as shown in FIG. 2, the partition part 7b, 7b .. is formed inside the bottom part 2. As shown in FIG. Further, partition portions 7c, 7c,... Are formed on the walls 3a, 3c, respectively. In this case, each partitioning portion 7a, 7b, 7c partitions a plurality (20 in this case) of storage spaces 20 (refer to FIG. 2) for storing the tape cartridge 200, and as shown in FIG. The tape cartridge 200 has a function of storing it in a state of being separated from each other.

  Next, the usage method of the storage container 1 is demonstrated with reference to drawings.

  First, as shown in FIGS. 1, 2, and 5, the storage container 1 is placed with the opening 10a facing upward (hereinafter, the storage container 1 is also referred to as “storage container 1A”). Next, as shown in FIG. 2, for example, the tape cartridge 200 is stored in the storage space 20 at the lower left corner partitioned by the partition portions 7a, 7b, and 7c in the storage container 1A. Subsequently, the tape cartridges 200 are sequentially stored in the storage spaces 20, 20,... Partitioned by the partition portions 7a, 7b, 7c (see FIG. 6).

  Next, as shown in FIG. 7, other storages of the same type as shown in FIG. 7 are stored in the storage containers 1A in which the tape cartridges 200 are stored in all (20 in this case) storage spaces 20, as shown in FIG. The container 1 (hereinafter, this storage container 1 is also referred to as “storage container 1B”) is covered with the opening 10a facing downward. At this time, the respective flange portions 4 of the two storage containers 1A and the respective flange portions 4 of the storage container 1B are brought into contact with each other, and the respective opening side fitting portions 11 of the two storage containers 1A and 1B are fitted to each other. . As a result, the storage containers 1A and 1B are connected to each other via the respective opening side fitting portions 11, and the storage boxes 100 (hereinafter, this storage box 100 is also referred to as “storage box 100A”) by the storage containers 1A and 1B. ) Is configured. In this case, since each tape cartridge 200 is stored in a separated state by the partition portions 7a, 7b, and 7c, for example, even if the storage box 100 vibrates when the storage box 100 is transported, the storage box 100 A situation in which the tape cartridge 200 is damaged due to the sliding movement between the tape cartridges 200 is reliably prevented. Further, since the tape cartridge 200 is stored in the storage space 20 partitioned by the partition portions 7a, 7b, and 7c, even if the tape cartridge 200 is not stored in all the storage spaces 20, there is no space in the storage space 20. Even if there is, rattling of the tape cartridge 200 is reliably prevented.

  Further, in the storage container 1, the opening-side fitting portion 11 is formed in a point-symmetric shape with respect to the center 2x of the bottom portion 2 in the plan view. For this reason, each opening part fitting part 11 makes the center 2x with respect to 1A of storage containers 1B from the position which can fit each opening part fitting part 11 in both storage containers 1A and 1B. The fitting is possible even at a position half-rotated as the center of rotation. Therefore, when the storage container 1B is covered with the storage container 1A, there is no need to confirm the up / down / left / right orientation (hereinafter, also simply referred to as “direction”) about the center 2x in the storage container 1B. The efficiency of the storing operation of 200 can be sufficiently improved.

  Next, in the same manner as described above, the tape cartridge 200 is stored in a new storage container 1 (hereinafter, this storage container 1 is also referred to as “storage container 1C”), and another new storage of the same type is stored in the storage container 1C. The container 1 (hereinafter, this storage container 1 is also referred to as “storage container 1D”) is covered, and both the storage containers 1C and 1D are connected via the respective opening side fitting portions 11. Thus, a second storage box 100 in which the tape cartridge 200 is stored (hereinafter, this storage box 100 is also referred to as “storage box 100B”) is configured.

  Subsequently, as shown in FIG. 8, the storage boxes 100B are stacked on the storage box 100A. In this case, the bottom 2 of the storage container 1B constituting the storage box 100A and the bottom 2 of the storage container 1C constituting the storage box 100B are brought into contact with each other. At this time, as shown in FIG. 9 and FIG. 9, the second convex portion 32 of the storage container 1C is fitted to the outer wall of the first convex portion 31 of the storage container 1B. Moreover, as shown in FIG. 8, the 2nd convex part 32 of the storage container 1B fits the outer wall of the 1st convex part 31 of the storage container 1C. In this case, the direction along the side 32b of the second convex portion 32 by the fitting of the first convex portion 31 and the second convex portion 32 (for example, the short direction of the storage container 1 and the vertical direction in FIG. 9). The relative movement of each storage container 1 (each storage box 100) is restricted.

  Moreover, as shown in FIG. 9, the 3rd convex part 33 of the storage container 1C fits the inner wall of the 1st convex part 31 of the storage container 1B. Moreover, the 3rd convex part 33 of the storage container 1B fits the inner wall of the 1st convex part 31 of the storage container 1C. In this case, the direction along the sides 32a and 32a of the second convex portion 32 by fitting the first convex portion 31 and the third convex portion 33 (for example, the longitudinal direction of the storage container 1, The relative movement of each storage container 1 (storage box 100) in the left-right direction is restricted. Thereby, storage box 100A, 100B is connected via each bottom part side fitting part 12, and the shift | offset | difference of both is prevented.

  In this case, in the storage container 1, the bottom-side fitting portions 12 are formed in a point-symmetric shape with respect to the center 2x of the bottom portion 2 with respect to the center 2x of the bottom portion 2. For this reason, each bottom side fitting part 12 is centered on the center 2x of the storage container 1C with respect to the storage container 1B from the position where the bottom side fitting parts 12 of the two storage containers 1B and 1C can be fitted to each other. Can be fitted even at a half-rotated position. Therefore, when stacking the storage box 100B on the storage box 100A, the work of confirming the orientation of the storage container 1C is unnecessary. As a result, the efficiency of the stacking work can be improved accordingly.

  Hereinafter, the above operation is repeated to store the tape cartridge 200 in the storage container 1 (storage box 100). In this case, in the storage container 1, a notch portion 5 is formed at the center portion of two short sides facing each other in the four sides constituting the flange portion 4. For this reason, as shown in FIG. 10, even when a plurality of stacked storage boxes 100 are arranged so as to be in close contact with each other, a gap 2 between the adjacent storage containers 1 of the same type by the notch 5 is provided. There is a gap in which the two notches 5 overlap. For this reason, for example, when the storage boxes 100 that have been transported and stored in a state of being stacked and arranged in this manner are lifted and moved one by one, a hand is inserted into the gap, that is, the formation part of the notch 5. As a result of being able to easily grasp the collar 4, it is possible to improve the efficiency of the moving work.

  Next, as shown in FIG. 11, the length in the longitudinal direction (the left-right direction in the figure) at the bottom is defined to be longer than the length in the longitudinal direction at the bottom 2 of the storage container 1, and is formed at the bottom 302. Another type of storage container 301 (corresponding to the second storage container) whose shape of the bottom side fitting part 312 is different from the shape of the bottom side fitting part 12 of the storage container 1 (corresponding to the first storage container) described above. And the stacking method of the storage container which stacks the storage container 1 is demonstrated. As an example, a method of stacking the storage box 100 storing the tape cartridge 200 on the storage box 300 (see FIG. 12) storing the tape cartridge 200 in the storage container 301 will be described. In this case, as shown in FIG. 11, the bottom portion 302 of the storage container 301 is formed in a point-symmetric shape with respect to the center 302x of the bottom portion 302 with respect to the center 302x. The bottom side fitting part 312 which can be mutually fitted in the state of abutting with the bottom part 302 of the storage container 301 is formed.

  Further, as shown in FIG. 11, the bottom-side fitting portion 312 includes four divided regions 302 a to 302 d having a substantially rectangular shape in a plan view obtained by dividing the bottom 302 into four so as to be positioned around the center 302 x of the bottom 302. The other two except for the fifth convex part 331 protruding from the two divided areas 302a and 302c located at the diagonal position and the two divided areas 302a and 302c formed with the fifth convex part 331. A sixth convex portion 332 is formed to project from the divided regions 302b and 302d. As shown in the figure, the fifth convex portion 331 is formed in a substantially rectangular shape in plan view having a longer length in the longitudinal direction than the first convex portion 31 of the storage container 1. Further, the sixth convex portion 332 is formed in a substantially rectangular frame shape in plan view that can be fitted to the outer wall of the fifth convex portion 331. In addition, a partition portion having the same function as the partition portion 7b of the storage container 1 is formed inside the bottom portion 302 of the storage container 301, and a portion where the partition portion is formed on the outer surface of the storage container 301 is a dent (hereinafter referred to as “this”). The recess is also referred to as “recess 307b”). In this case, the concave portion 307b is formed so that the third convex portion 33 of the storage container 1 is fitted in a state where the bottom portion 302 of the storage container 301 and the bottom portion 2 of the storage container 1 are abutted.

  When the storage box 100 storing the tape cartridge 200 in the storage container 1 is stacked on the storage box 300 storing the tape cartridge 200 in the storage container 301 configured as described above, as shown in FIG. The bottom 302 of the storage container 301 that constitutes the box 300 is brought into contact with the bottom 2 of the storage container 1 that constitutes the storage box 100. In this case, for example, the second convex portion 32 of the storage container 1 is formed in a frame shape (a shape in which both ends of the sides 32a and 32a are connected by the two sides 32b and the outer short side is not missing). When there is, the fifth convex portion 331 and the second convex portion 32 of the storage container 301 that are longer in the longitudinal direction than the first convex portion 31 of the storage container 1 collide with each other, and both cannot be fitted. On the other hand, in this storage container 1, the 2nd convex part 32 is formed in planar view U shape which the outer side which leaves | separates from the center 2x lacked. For this reason, as shown in FIG. 13, the second convex portion 331 and the second convex portion 32 of the storage container 301 that are longer in the longitudinal direction than the first convex portion 31 of the storage container 1 do not collide with each other. The convex part 32 is securely fitted to the outer wall of the fifth convex part 331. Further, as shown in the figure, the third convex portion 33 is fitted into the concave portion 307 b formed on the outer surface of the bottom portion 302 of the storage container 301.

  In this case, each storage in the direction along the side 32b of the second convex part 32 (for example, the short direction and the vertical direction in FIG. 13) by fitting the fifth convex part 331 and the second convex part 32. The relative movement of the containers 1 and 301 is restricted, and the direction along the sides 32a and 32a of the second convex portion 32 (for example, the longitudinal direction) by fitting the concave portion 307b and the third convex portion 33, The relative movement of each storage container 1,301 in the left-right direction in FIG. Accordingly, the storage box 100 is stacked on the storage box 300 in a state where the bottom side fitting portion 312 of the storage container 301 of the storage box 300 and the bottom side fitting portion 12 of the storage container 1 of the storage box 100 are fitted. It is done. Note that, of course, the storage box 300 can be stacked on the storage box 100 contrary to the above.

  In this case, the bottom-side fitting portion 12 of the storage container 1 is formed in a point-symmetric shape with the center 2x of the bottom portion 2 as a symmetric point in plan view, so that the storage box 100 is stacked on the storage box 300. In this case, or when the storage box 300 is stacked on the storage box 100, the storage boxes 300 are stacked even if rotated 180 °. Therefore, the work for confirming the orientation of the storage container 1 becomes unnecessary, and as a result, the efficiency of the stacking work can be improved.

  Thus, in this storage container 1, the 1st convex part 31 formed in the division area 2a, 2c located in the diagonal position of each division area 2a-2d of planar view substantially rectangular shape which divided | segmented the bottom into four. And the second convex portion 32 and the third convex portion 33 formed in the divided regions 2b and 2d, the bottom side fitting portion 12 is configured, and the second convex portion 32 is formed in a U shape in plan view. Yes. Therefore, according to the storage container 1 and the stacking method of the storage containers, the shape of the bottom side fitting portion 312 formed on the bottom 302 is different from the shape of the bottom side fitting portion 12 in the storage container 1. When the storage container 1 is stacked, the bottom side fitting portion 312 of the storage container 301 is longer in the longitudinal direction than the length in the direction along the sides 32a, 32a of the second convex portion 32 in the storage container 1. Even when the fifth convex portion 331 having a long rectangular shape in plan view is provided, the second convex portion 32 can be reliably fitted to the outer wall of the fifth convex portion 331. That is, according to the stacking method of the storage container 1 and the storage container, another type of storage in which the shape of the bottom side fitting portion 312 formed on the bottom portion 302 is different from the shape of the bottom side fitting portion 12 of the storage container 1. The container 301 can be stacked. Therefore, another type of storage box 300 in which the tape cartridge 200 as a storage object is stored in another type of storage container 301 in which the shape of the bottom side fitting portion 312 is different from the shape of the bottom side fitting portion 12 of the storage container 1. Even when the storage container 100 containing the tape cartridges 200 is mixed in the storage container 1, both can be stacked, so that the efficiency of the stacking operation can be sufficiently improved.

  Further, according to the storage container 1, the storage box 100 is mounted on the storage box 100 by forming the bottom side fitting portion 12 in a point-symmetric shape with respect to the center 2x of the bottom portion 2 as a symmetry point. In addition to the case of stacking, in the case of stacking the storage boxes 100 on the storage box 300, the work of confirming the orientation of the storage container 1 can be made unnecessary. As a result, the efficiency of the stacking work can be further improved.

  Moreover, according to this storage container 1, the planar view L-shape formed in the division | segmentation site | part 4a, 4c located in the diagonal position among the planar view L-shaped division | segmentation site | parts 4a-4d which divided | segmented the collar part 4. FIG. A concave portion 41, and a fourth convex portion 42 formed in the divided portions 4b and 4d excluding the divided portions 4a and 4c and fitted with the concave portions 41 of other storage containers 1 of the same type in plan view. In the first abutting state, the opening side fitting portion 11 is configured so that the mouth edges of the respective opening portions 10a in the two storage containers 1 are sufficiently infiltrated with dust over the entire area. It can be occluded preventably. For this reason, according to this storage container 1, the process which encloses the storage box 100 which accommodated the tape cartridge 200 in the bag for dust intrusion prevention, etc. can be made unnecessary.

  Moreover, according to this storage container 1, since the notch part 5 was formed in the center part of two sides which mutually oppose in the four sides which comprise the collar part 4, several stacked storage boxes 100 were adjoined. Even when they are arranged so as to be in close contact with each other, a gap can be formed between the adjacent two other storage containers 1 (storage boxes 100) by overlapping the two cutout portions 5. For this reason, when the storage boxes 100 in a state of being stacked and arranged in this manner are lifted and moved one by one, the hand 4 is easily grasped by inserting a hand into the formation part of the notch 5 that is the gap. As a result, the efficiency of the moving work can be improved.

  Moreover, according to this storage container 1, the opening part 10a and the bottom part 2 are each formed in a substantially rectangular shape, and the notch part 5 is formed in the center part of two short sides facing each other in the four sides constituting the flange part 4. By forming each, the storage container 1 is stabilized when the storage container 1 (storage box 100) in which the tape cartridge 200 is stored is moved in a state where the notch 5 is formed in the collar part 4. Therefore, it is possible to further improve the efficiency of the moving work.

  The storage container 1 is not limited to the configuration described above. For example, with respect to an example in which the opening 10a, the bottom 2 and the divided regions 2a to 2d are each substantially rectangular, and the longitudinal direction thereof is the direction along the sides 32a and 32a of the second convex portion 32. As described above, adopting a configuration in which each longitudinal direction is formed along the side 32b of the second convex portion 32 (that is, so as to form a vertically long substantially rectangular shape in FIGS. 2 and 4). You can also. Moreover, the structure which forms so that the opening part 10a, the bottom part 2, and each division area 2a-2d may each make a substantially square shape is also employable. Further, the storage container 1 (storage box 100) that can store 20 tape cartridges 200 has been described as an example. However, the number of tape cartridges 200 that can be stored is not limited to 20 and may be arbitrarily defined. it can. Moreover, although it described above about the structural example which formed the notch part 5 in the center part of two short sides (short side) mutually opposed among the four sides which comprise the collar part 4, It is also possible to employ a configuration in which the notch 5 is formed in the center of the two long sides (long sides). Furthermore, not only the structure which forms the notch part 5 only in the center part of two sides which mutually oppose in the four sides which comprise the collar part 4, but the notch part 5 is formed in all the center parts of four sides. A configuration can also be adopted. Further, the present invention is not limited to the tape cartridge 200, and can be applied to the storage container 1 for storing a tape cartridge other than the tape cartridge 200, various recording media, various small items, and the like.
