[0021] Hereinafter, an example of an embodiment of a storage case and a package according to the technology of the present disclosure will be described with reference to the drawings.

[0022] First, an example of the configuration of storage case 10 will be described with reference to Figures 1 to 7. For convenience of explanation, in the following description, the direction of arrow A in Figures 1 to 4 is the upward direction of storage case 10, and the upward side of storage case 10 is the upper side of storage case 10. In the following description of the structure, "upper" refers to the upper side of storage case 10.

[0023] 1 and 2, for convenience of explanation, the direction opposite to the direction of arrow A is referred to as the downward direction, and the downward side of storage case 10 is referred to as the lower side of storage case 10. In the explanation of the structure given below, "lower" refers to the lower side of storage case 10.

[0024] 1 and 2, for convenience of explanation, the direction of arrow B perpendicular to the direction of arrow A is defined as the front direction of storage case 10, and the side of storage case 10 in the front direction is defined as the front side of storage case 10. In the explanation of the structure given below, "front" refers to the front side of storage case 10.

[0025] 1 and 2, for convenience of explanation, the direction opposite to the direction of arrow B is referred to as the rear direction, and the rear side of the storage case 10 is referred to as the rear side of the storage case 10. In the explanation of the structure given below, "rear" refers to the rear side of the storage case 10.

[0026] 1 and 2, for convenience of explanation, the direction perpendicular to the directions of arrows A and B is indicated by arrow C, the direction of arrow C is the leftward direction of storage case 10, and the leftward side of storage case 10 is the left side of storage case 10. In the explanation of the structure given below, "left" refers to the left side of storage case 10.

[0027] 1 and 2, for convenience of explanation, the direction opposite to the direction of the arrow C is referred to as the right direction, and the rightward side of the storage case 10 is referred to as the right side of the storage case 10. In the explanation of the structure given below, "right" refers to the right side of the storage case 10.

[0028] In the following description, when directions are indicated, the storage case 10 will be abbreviated to "case" such as the case up-down direction, the case front-rear direction, and the case left-right direction.

[0029] The front-rear and left-right directions of the storage case 10 are not limited to those shown in FIG.

[0030] 2, the storage case 10 is used to store a plurality of magnetic tape cartridges 50. In the following description, the magnetic tape cartridges 50 will be abbreviated to cartridges 50 as appropriate.

[0031] As an example, the cartridge 50 has a flat shape. A cartridge reel (not shown) is housed inside the cartridge 50. The cartridge reel is rotatably supported by a rotation support mechanism (not shown) inside the cartridge 50. A magnetic tape (not shown) is wound around the outer circumferential surface of the cartridge reel. The direction of the rotation axis of the cartridge reel corresponds to the thickness direction of the cartridge 50.

[0032] As an example, as shown in Fig. 2, storage case 10 includes a lower case 12 and an upper case 14. Lower case 12 forms the lower half of storage case 10. Upper case 14 forms the upper half of storage case 10. Storage case 10 is formed by assembling lower case 12 and upper case 14 in the vertical direction. Lower case 12 is an example of a "first case member" according to the technology of the present disclosure. Upper case 14 is an example of a "second case member" according to the technology of the present disclosure.

[0033] A plurality of storage chambers 11 are formed inside the storage case 10. As an example, four storage chambers 11 are formed inside the storage case 10. Each storage chamber 11 has a size that can store a plurality of cartridges 50 lined up in the thickness direction of the cartridges 50. As an example, each storage chamber 11 has a size that can store five cartridges 50 lined up in the thickness direction of the cartridges 50. Therefore, when five cartridges 50 are stored in each storage chamber 11, the storage case 10 can store a total of 20 cartridges 50.

[0034] As an example, as shown in FIGS. 2 and 3, the lower case 12 has a bottom plate 16, a peripheral wall 18, and a flange portion 20.

[0035] The bottom plate 16 is formed in a rectangular shape in a plan view (see FIG. 3). Here, "rectangular shape in a plan view" includes a rectangle with arc-shaped corners in a plan view.

[0036] The peripheral wall 18 is erected on the peripheral edge of the bottom plate 16. The peripheral wall 18 is formed in a rectangular frame shape in a plan view (see FIG. 3). Here, "rectangular frame shape in a plan view" includes a rectangular frame whose corners and / or edges are curved in an arc shape in a plan view. As an example, the peripheral wall 18 has a front wall portion 18A located in the front of the case, a rear wall portion 18B located toward the rear of the case, a right wall portion 18C located toward the right of the case, and a left wall portion 18D located toward the left of the case.

[0037] The flange portion 20 protrudes from the upper end of the peripheral wall 18 toward the side opposite the bottom plate 16. As an example, the flange portion 20 has flange portions 20A, 20B, 20C, and 20D. The flange portion 20A is a portion that protrudes from the front wall portion 18A. The flange portion 20B is a portion that protrudes from the rear wall portion 18B. The flange portion 20C is a portion that protrudes from the right wall portion 18C. The flange portion 20D is a portion that protrudes from the left wall portion 18D. A handle hole 22 is formed in each of the flange portions 20C and 20D. The handle hole 22 is used when a user carries the lower case 12.

[0038] The lower case 12 also has an engaging protrusion 24 and an engaging recess 26. The engaging protrusion 24 is formed on the surface of the flange portion 20. As an example, the engaging protrusion 24 extends on the surface of the flange portion 20 along the circumferential direction of the peripheral wall 18. In detail, the engaging protrusion 24 extends from the center of the flange portion 20C in the case front-rear direction through the flange portion 20B to the center of the flange portion 20D in the case front-rear direction. The engaging recess 26 has a shape that engages with the engaging protrusion 24. The engaging protrusion 24 is formed on the surface of the flange portion 20. As an example, the engaging recess 26 extends on the surface of the flange portion 20 along the circumferential direction of the peripheral wall 18. In detail, the engaging protrusion 24 extends from the center of the flange portion 20C in the case front-rear direction through the flange portion 20A to the center of the flange portion 20D in the case front-rear direction.

[0039] 2 and 3, the bottom plate 16 is provided with a first rib 28 and a second rib 30. As an example, the first rib 28 is a protrusion formed by protruding upward from the bottom plate 16. The first rib 28 extends in the front-rear direction of the case from the center of the front wall portion 18A in the left-right direction of the case to the center of the rear wall portion 18B in the left-right direction of the case.

[0040] As an example, the second rib 30 is a protrusion formed by protruding the bottom plate 16 upward. The second rib 30 extends in the left-right direction of the case from the center of the right wall portion 18C in the front-rear direction of the case to the center of the left wall portion 18D in the front-rear direction of the case. The first rib 28 and the second rib 30 are connected to each other at the center of the bottom plate 16.

[0041] As an example, the first rib 28 and the second rib 30 divide the interior of the lower case 12 into four storage areas 32. The four storage areas 32 of the lower case 12 form the four storage chambers 11 of the storage case 10. As shown in Fig. 3 as an example, the storage area 32 is an area surrounded by the peripheral wall 18, the first rib 28, and the second rib 30 in a plan view.

[0042] 2 and 3, the bottom plate 16 has support portions 34 formed in areas corresponding to the respective storage areas 32. The support portions 34 have a support surface 35 that supports the side surfaces 50B of the multiple cartridges 50. The support portions 34 also have an inner support portion 36 and an outer support portion 38. The support surface 35 is an example of a "support surface" and a "first support surface" according to the technology of the present disclosure.

[0043] As an example, the inner support portion 36 is a protrusion formed by protruding upward from the bottom plate 16. The inner support portion 36 is formed in a rectangular shape in a plan view (see FIG. 3).

[0044] As an example, the outer support portion 38 is a protrusion formed by protruding the bottom plate 16 upward. The outer support portion 38 is formed in a rectangular frame shape in a plan view (see FIG. 3). The outer support portion 38 surrounds the inner support portion 36.

[0045] As an example, the support surface 35 has an outer support surface 39 and an inner support surface 37. The outer support surface 39 is an example of a "first surface" according to the technology of the present disclosure. The inner support surface 37 is an example of a "second surface" according to the technology of the present disclosure.

[0046] As an example, the outer support surface 39 is an upper surface of the outer support portion 38. The outer support surface 39 is formed in a rectangular frame shape in a plan view. The outer support surface 39 is located on the outer circumferential edge side of the support surface 35.

[0047] As an example, the inner support surface 37 is the upper surface of the inner support portion 36. The inner support surface 37 is formed in a rectangular shape in a plan view. The inner support surface 37 is a flat surface. The inner support surface 37 is located closer to the center of the support surface 35 than the outer support surface 39. Here, the term "flat surface" refers to a completely flat surface as well as a flat surface including an error that is generally acceptable in the technical field to which the technology of the present disclosure belongs and that does not go against the spirit of the technology of the present disclosure.

[0048] 4, the inner support surface 37 is located closer to the side surface 50B of the cartridge 50 than the outer support surface 39. Here, being located closer to the side surface 50B of the cartridge 50 means that the inner support surface 37 is located higher in the case than the outer support surface 39 in the lower case 12.

[0049] 5, a step 40 is formed between the outer support surface 39 and the inner support surface 37. The dimension H of the step 40 in the case up-down direction is 0.1 mm or more and 1.3 mm or less.

[0050] As an example, the cartridge 50 is stored in the storage area 32 of the lower case 12 with the side surface 50A (see FIG. 1) facing upward in the direction in which the cartridge 50 is loaded into the drive device (not shown). In this case, the side surface 50B of the cartridge 50 opposite to the side surface 50A is supported by the support surface 35 (see FIG. 4). Here, the central portion 50BA in the longitudinal direction of the side surface 50B of the cartridge 50 is supported by the inner support surface 37. Meanwhile, the end portion (i.e., the edge portion) 50BB in the longitudinal direction of the side surface 50B of the cartridge 50 is supported by contacting the outer support surface 39. For example, when the outer support surface 39 is subjected to vibration during transportation, the outer support surface 39 supports the side surface 50B of the cartridge 50 by contacting the side surface 50B of the cartridge 50. Here, the longitudinal direction of the side surface 50B corresponds to the front-rear direction of the case when the cartridge 50 is stored in the storage case 10.

[0051] As an example, as shown in FIG. 4, a rectangular frame portion 42 is formed on the lower surface of the bottom plate 16 between the inner support portion 36 and the outer support portion 38 (see FIG. 2).

[0052] 3, two support parts 34 located on the front side of the case from a center line CL passing through the center of the case in the front-rear direction of the lower case 12 and two support parts 34 located on the rear side of the case from the center line CL have different sizes of inner support surfaces 37. In the following description, the two support parts 34 located on the front side of the case from the center line CL will be referred to as support parts 34A, and the two support parts 34 located on the rear side of the case from the center line CL will be referred to as support parts 34B.

[0053] As an example, the outer size of the inner support portion 36 at the support portion 34A is larger than the outer size of the inner support portion 36 at the support portion 34B.

[0054] As an example, frame portion 42 formed on the opposite side of support portion 34A in bottom plate 16 will be referred to as frame portion 42A below. Also, frame portion 42 formed on the opposite side of support portion 34B in bottom plate 16 will be referred to as frame portion 42B below. Frame portion 42B is sized to fit inside frame portion 42A.

[0055] As an example, as shown in Fig. 6, the shape of the upper case 14 and the shape of the lower case 12 are the same. Here, "same" refers to the same in the sense of including an error that is generally acceptable in the technical field to which the technology of the present disclosure belongs, as well as an error that does not go against the spirit of the technology of the present disclosure, in addition to the exact same. For this reason, in Fig. 6, the reference numerals attached to the respective parts of the upper case 14 are the same as the reference numerals attached to the respective parts of the lower case 12, except for the top plate 17 that corresponds to the bottom plate 16.

[0056] The support surface 35 of the upper case 14 is an example of a "support surface" and a "second support surface" according to the technology of the present disclosure. The outer support surface 39 of the upper case 14 is an example of a "first surface" according to the technology of the present disclosure. The inner support surface 37 of the upper case 14 is an example of a "second surface" according to the technology of the present disclosure.

[0057] Here, the lower case 12 and the upper case 14 are overlapped in a direction in which the support surface 35 of the lower case 12 and the support surface 35 of the upper case 14 face each other, thereby forming a storage chamber 11 in the storage case 10. In detail, the upper case 14 is placed on the lower case 12 so that the surface of the flange portion 20 of the lower case 12 overlaps the surface of the flange portion 20 of the upper case 14. Then, the lower case 12 and the upper case 14 are assembled by engaging the engaging protrusion 24 and the engaging recess 26 of the lower case 12 with the engaging recess 26 and the engaging protrusion 24 of the upper case 14, respectively. Here, when the lower case 12 and the upper case 14 are assembled in a state in which a plurality of cartridges 50 are stored in the storage area 41 of the lower case 12, a plurality of cartridges 50 are stored in the storage case 10. As a result, a package 52 in which a plurality of cartridges 50 are stored in the storage case 10 is completed.

[0058] As an example, the lower case 12 and the upper case 14 are formed from a resin material. Examples of the resin material forming the lower case 12 and the upper case 14 include polyethylene terephthalate. In this embodiment, the lower case 12 and the upper case 14 are formed from polyethylene terephthalate. Also, as an example, the lower case 12 and the upper case 14 are each an integrally molded resin product. Therefore, the support surface 35 of the lower case 12 in this embodiment is formed from a resin material. Also, the support surface 35 of the upper case 14 in this embodiment is formed from a resin material.

[0059] As an example, as shown in FIG. 7, the lower surface 12A of the lower case 12 has a mating surface 12B including the frame portion 42A and the frame portion 42B. Also, the upper surface 14A of the upper case 14 has a mating surface 14B including the frame portion 42A and the frame portion 42B. Here, the mating surface 12B and the mating surface 14B are shaped to be overlapped with each other. For example, when the lower case 12 is placed on the upper case 14, the mating surface 12B of the lower case 12 is overlapped with the mating surface 14B of the upper case 14. Also, as an example, the lower case 12 has a mating surface 12C including the support surface 35. Here, the mating surface 12C of the lower case 12 and the mating surface 14B of the upper case 14 are shaped to be overlapped with each other. Also, as an example, the upper case 14 has a mating surface 14C including the support surface 35. Here, the mating surface 14C of the upper case 14 and the mating surface 12B of the lower case 12 are shaped to overlap each other. The mating surface 12C of the lower case 12 is an example of a "first mating surface" according to the technology of the present disclosure. The mating surface 14B of the upper case 14 is an example of a "second mating surface" according to the technology of the present disclosure.

[0060] Next, the effects of the storage case 10 will be described. In the storage case 10, the side surface 50B of the cartridge 50 is supported by the support surface 35 of the lower case 12. The support surface 35 has an outer support surface 39 and an inner support surface 37. The inner support surface 37 is located closer to the side surface 50B than the outer support surface 39. Therefore, the side surface 50B of the cartridge 50 is supported by the inner support surface 37. Therefore, according to this configuration, compared to a structure in which the entire support surface 35 supports the side surface 50B of the cartridge 50, for example, wear of the outer support surface 39 can be suppressed, and wear of the support surface 35 can be reduced accordingly. This reduces wear powder generated by wear of the support surface 35 of the lower case 12.

[0061] In the storage case 10, the outer support surface 39 is located on the outer peripheral edge side of the support surface 35, and the inner support surface 37 is located closer to the center of the support surface 35 than the outer support surface 39. Therefore, the inner support surface 37 supports the center portion 50BA of the side surface 50B of the cartridge 50. Therefore, according to this configuration, it is possible to suppress abrasion of the outer support surface 39 by the end portion 50BB of the cartridge 50, compared to a configuration in which the outer support surface 39 supports the end portion 50BB (i.e., the edge portion) of the side surface 50B of the cartridge 50, for example.

[0062] In the storage case 10, the support surface 35 is formed of a resin material. Therefore, according to this configuration, the support surface 35 can be deformed relative to the cartridge 50, as compared to, for example, a configuration in which the support surface 35 is formed of a metal material. This reduces the contact pressure between the cartridge 50 and the support surface 35, and can suppress damage to the side surface 50B of the cartridge 50.

[0063] In the storage case 10, the inner support surface 37 is a flat surface. Therefore, according to this configuration, the contact area between the inner support surface 37 and the side surface 50B of the cartridge 50 is increased compared to, for example, a configuration in which the support surface 35 is curved in an arc shape. This makes it possible to stabilize the storage posture of the cartridge 50.

[0064] In the storage case 10, a step 40 is formed between the inner support surface 37 and the outer support surface 39. The dimension of the step 40 is 0.1 mm or more and 1.3 mm or less. If the dimension of the step 40 is less than 0.1 mm, wear of the support surface 35 cannot be suppressed. On the other hand, if the dimension of the step 40 exceeds 1.3 mm, the balance of the cartridge 50 deteriorates. Therefore, according to this configuration, it is possible to achieve both suppression of wear of the support surface 35 and balance of the cartridge 50, compared to, for example, a case in which the dimension of the step 40 does not satisfy the range of 0.1 mm or more and 1.3 mm or less.

[0065] The storage case 10 has a plurality of support surfaces 35. Therefore, according to this configuration, for example, compared to a case in which there is one support surface 35, a plurality of cartridges 50 can be supported on each of the plurality of support surfaces 35. This allows a plurality of cartridges 50 to be stored in the storage case 10 in a dispersed manner.

[0066] In the storage case 10, the lower case 12 and the upper case 14 are made of polyethylene terephthalate. Therefore, according to this configuration, wear of the support surface 35 can be suppressed compared to, for example, a configuration in which the lower case 12 and the upper case 14 are made of a resin material that is prone to generating wear powder.

[0067] In the storage case 10, the lower case 12 and the upper case 14 each have a support surface 35. Therefore, according to this configuration, compared to a configuration in which, for example, either the lower case 12 or the upper case 14 does not have the support surface 35, it is possible to suppress the generation of wear powder due to wear of the support surfaces 35 of the lower case 12 and the upper case 14.

[0068] In the storage case 10, the cartridge 50 is stored by stacking the lower case 12 and the upper case 14 in a direction in which their support surfaces 35 face each other. The side surface 50B of the cartridge 50 is supported by the support surface 35 of the lower case 12. The side surface 50A of the cartridge 50 is supported by the support surface 35 of the upper case 14. Therefore, according to this configuration, the generation of wear powder due to wear of the support surfaces 35 of the lower case 12 and the upper case 14 can be suppressed compared to, for example, a configuration in which either the lower case 12 or the upper case 14 does not have the support surface 35.

[0069] In the storage case 10, the overlapping surface 12C of the lower case 12 and the overlapping surface 14B of the upper case 14 are overlapped with each other. Here, by placing the upper case 14 upside down inside the peripheral wall 18 of the lower case 12, the overlapping surface 12C of the lower case 12 and the overlapping surface 14B of the upper case 14 are overlapped with each other. Therefore, according to this configuration, for example, compared to a shape in which the overlapping surface 12C of the lower case 12 and the overlapping surface 12B of the upper case 14 are not overlapped with each other, it is possible to reduce the space (for example, the height of the cases stacked in multiple stages) when the lower case 12 and the upper case 14 are stacked in multiple stages. Also, in the storage case 10, the overlapping surface 12B of the lower case 12 and the overlapping surface 14B of the upper case 14 are overlapped with each other. For this reason, when another storage case 10 is stacked on top of a storage case 10, the overlapping surface 12B of the upper storage case 10 overlaps with the overlapping surface 14B of the lower storage case 10. Therefore, according to this configuration, rattling of the storage case 10 when multiple storage cases 10 are stacked can be suppressed compared to, for example, a shape in which the overlapping surfaces 12B of the lower case 12 and the overlapping surfaces 12B of the upper case 14 do not overlap each other.

[0070] In the package 52, a plurality of cartridges 50 are stored in a storage case 10 to which an example of the technology according to the present disclosure is applied. Therefore, according to this configuration, for example, compared to a structure in which the storage case 10 supports the side surface 50B of the cartridge 50 with the entire support surface 35, it is possible to reduce wear of the support surface 35 by suppressing wear caused by the outer support surface 39. This makes it possible to reduce wear powder generated by wear of the support surface 35.

[0071] In the above embodiment, the lower case 12 and the upper case 14 are made of polyethylene terephthalate, but the technology of the present disclosure is not limited to this configuration. For example, the lower case 12 and the upper case 14 may be made of polypropylene or polystyrene.

[0072] In the storage case 10, the side surface 50A of the cartridge 50 is supported by the support surface 35 of the upper case 14. Therefore, the support surface 35 of the upper case 14 can achieve the same effect as the support surface 35 of the lower case 12.

[0073] In the above embodiment, the lower case 12 and the upper case 14 have the same shape, but the technology of the present disclosure is not limited to this configuration, and the lower case 12 and the upper case 14 may have different shapes. For example, the lower case 12 may be the case body of the storage case, and the upper case 14 may be the lid of the storage case. Even in this case, by providing the case body and the lid with the support surface 35, the same effect as the storage case 10 of the above embodiment can be achieved.

[0074] In the above embodiment, the support surface 35 is formed of a resin material, but the technology of the present disclosure is not limited to this configuration. For example, as shown in FIG. 8, a sheet-like soft member 60 may be provided on the upper surface of the support portion 34. Here, the surface of the soft member 60 corresponds to the support surface 35. Examples of the soft member 60 include a cloth material such as felt and / or a cushioning material such as sponge. In this case, damage to the side surface of the cartridge 50 can be suppressed compared to a configuration in which the support surface 35 is formed of a resin material.

[0075] In the above embodiment, the side surface 50B of the cartridge 50 is linear, but the central portion 50BA of the side surface 50B may be recessed toward the inner periphery of the cartridge 50 more than the end portion 50BB of the side surface 50B. Even if the shape of the side surface 50B of the cartridge 50 is recessed toward the inner periphery of the cartridge 50 as described above, in the storage case 10, the end portion 50BB of the side surface 50B is supported by the outer support surface 39, and the central portion 50BA of the side surface 50B is supported by the inner support surface 37. Therefore, according to this configuration, for example, scraping of the outer support surface 39 by the end portion 50BB of the side surface 50B can be suppressed compared to a configuration in which the end portion 50BB (i.e., the edge portion) of the side surface 50B is supported only by the outer support surface 39.

[0076] In the above embodiment, the upper case 14 is assembled on the lower case 12, but the technology of the present disclosure is not limited to this configuration. For example, the upper case 14 may be used as the lower case, and the lower case 12 may be used as the upper case. In this case, the upper case 14 is an example of a "first case member" according to the technology of the present disclosure. The lower case 12 is an example of a "second case member" according to the technology of the present disclosure.

[0077] In the above embodiment, the storage case 10 includes the lower case 12 and the upper case 14, but the technology of the present disclosure is not limited to this configuration. For example, the storage case 10 may be formed of only the lower case 12.
