[0030] Hereinafter, an example of an embodiment of the storage box and packaging material according to the present invention will be described with reference to the accompanying drawings.

[0031] First, refer to Figures 1 to 7 An example of the structure of the storage box 10 will be described below. Furthermore, in the following description, for ease of explanation, [the following will be used...]. Figures 1-4 In the diagram, the direction of arrow A is defined as the upward direction of storage box 10, and the side of the upward direction of storage box 10 is defined as the upper side of storage box 10. In the following structural description, "upper" refers to the upper side of storage box 10.

[0032] Furthermore, in the following explanation, for ease of explanation, Figure 1 and Figure 2 In the following structural description, the direction opposite to that of arrow A is defined as the downward direction, and the downward side of storage box 10 is defined as the lower side of storage box 10. In the following structural description, "down" refers to the lower side of storage box 10.

[0033] Furthermore, in the following explanation, for ease of explanation, Figure 1 and Figure 2In the diagram, the direction of arrow B, which is orthogonal to the direction of arrow A, is defined as the front direction of storage box 10, and the side facing the front direction of storage box 10 is defined as the front side of storage box 10. In the following structural description, "front" refers to the front side of storage box 10.

[0034] Furthermore, in the following explanation, for ease of explanation, Figure 1 and Figure 2 In the following structural description, the direction opposite to that of arrow B is defined as the rear direction, and the rear side of storage box 10 is defined as the rear side of storage box 10. In the following structural description, "rear" refers to the rear side of storage box 10.

[0035] Furthermore, in the following explanation, for ease of explanation, Figure 1 and Figure 2 In the diagram, arrow C represents a direction orthogonal to both arrow A and arrow B. Arrow C is defined as the left direction of storage box 10, and the left side of storage box 10 is defined as its left side. In the following structural description, "left" refers to the left side of storage box 10.

[0036] Furthermore, in the following explanation, for ease of explanation, Figure 1 and Figure 2 In the diagram, the direction opposite to arrow C is defined as the right direction, and the right side of storage box 10 is defined as the right side of storage box 10. In the following structural description, "right" refers to the right side of storage box 10.

[0037] Furthermore, in the following description, when indicating direction, such as the vertical direction of the housing, the front-back direction of the housing, or the left-right direction of the housing, the storage box 10 will be abbreviated as "housing".

[0038] In addition, the front-back and left-right directions of the storage box 10 are not limited to... Figure 1 The direction shown.

[0039] As an example, such as Figure 2 As shown, the storage box 10 is used to hold multiple cassette tape cassettes 50. In the following description, the cassette tape cassette 50 will be appropriately abbreviated as box 50.

[0040] As an example, the box 50 is flat in shape. The box 50 contains a box reel (not shown). The box reel is rotatably supported by a rotating support mechanism (not shown) within the box 50. A magnetic tape (not shown) is wound around the outer periphery of the box reel. The rotation axis of the box reel corresponds to the thickness direction of the box 50.

[0041] As an example, such as Figure 2As shown, the storage box 10 includes a lower shell 12 and an upper shell 14. The lower shell 12 forms the lower half of the storage box 10. The upper shell 14 forms the upper half of the storage box 10. The storage box 10 is formed by assembling the lower shell 12 and the upper shell 14 in a vertical direction. The lower shell 12 is an example of a "first shell component" according to the technology of the present invention. The upper shell 14 is an example of a "second shell component" according to the technology of the present invention.

[0042] Multiple receiving chambers 11 are formed inside the storage box 10. For example, four receiving chambers 11 are formed inside the storage box 10. Each receiving chamber 11 is large enough to accommodate multiple boxes 50 arranged in the thickness direction of the box 50. For example, each receiving chamber 11 is large enough to accommodate five rolls of boxes 50 arranged in the thickness direction of the box 50. Therefore, when five rolls of boxes 50 are accommodated in each receiving chamber 11, the storage box 10 can accommodate a total of 20 rolls of boxes 50.

[0043] As an example, such as Figure 2 and Figure 3 As shown, the lower housing 12 has a base plate 16, a peripheral wall 18, and a flange portion 20.

[0044] The base plate 16 appears rectangular when viewed from above (reference). Figure 3 Here, "rectangular shape when viewed from above" also includes rectangles whose corners are curved into rounded arcs when viewed from above.

[0045] The peripheral wall 18 is erected around the perimeter of the base plate 16. Furthermore, when viewed from above, the peripheral wall 18 forms a rectangular frame (see reference). Figure 3 Here, "rectangular frame in top view" also includes a rectangular frame in top view where the corners and / or sides are curved into arcs. As an example, the peripheral wall 18 has a front wall portion 18A in the direction of the front of the shell, a rear wall portion 18B in the direction of the rear of the shell, a right wall portion 18C in the direction of the right of the shell, and a left wall portion 18D in the direction of the left of the shell.

[0046] The flange portion 20 protrudes from the upper end of the peripheral wall 18 toward the side opposite to the base plate 16. As an example, the flange portion 20 has flange portions 20A, 20B, 20C, and 20D. Flange portion 20A protrudes from the front wall portion 18A. Flange portion 20B protrudes from the rear wall portion 18B. Flange portion 20C protrudes from the right wall portion 18C. Flange portion 20D protrudes from the left wall portion 18D. Handle holes 22 are formed on flange portions 20C and 20D respectively. The handle holes 22 are used by the user when carrying the lower housing 12.

[0047] Furthermore, the lower housing 12 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 along the circumferential direction of the peripheral wall 18 on the surface of the flange portion 20. Specifically, the engaging protrusion 24 extends from the central portion of the flange portion 20C in the front-rear direction of the housing through the flange portion 20B to the central portion of the flange portion 20D in the front-rear direction of the housing. 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 along the circumferential direction of the peripheral wall 18 on the surface of the flange portion 20. Specifically, the engaging protrusion 24 extends from the central portion of the flange portion 20C in the front-rear direction of the housing through the flange portion 20A to the central portion of the flange portion 20D in the front-rear direction of the housing.

[0048] As an example, such as Figure 2 and Figure 3 As shown, a first rib 28 and a second rib 30 are provided on the base plate 16. As an example, the first rib 28 is a protrusion formed by protruding the base plate 16 upward. The first rib 28 extends from the center of the front wall portion 18A in the left-right direction along the front-back direction to the center of the rear wall portion 18B in the left-right direction.

[0049] As an example, the second rib 30 is a protrusion formed by causing the base plate 16 to bulge upwards. The second rib 30 extends from the center of the right wall portion 18C in the front-rear direction of the housing along the left-right direction of the housing to the center of the left wall portion 18D in the front-rear direction of the housing. The first rib 28 and the second rib 30 are connected to each other at the center of the base plate 16.

[0050] As an example, the interior of the lower housing 12 is divided into four receiving areas 32 by the first rib 28 and the second rib 30. These four receiving areas 32 of the lower housing 12 form four receiving chambers 11 of the storage box 10. As an example, such as... Figure 3 As shown, the accommodating area 32 is the area surrounded by the peripheral wall 18, the first rib 28 and the second rib 30 when viewed from above.

[0051] As an example, such as Figure 2 and Figure 3 As shown, a support portion 34 is formed on the base plate 16 in the region corresponding to each receiving area 32. The support portion 34 has a support surface 35 that supports the side surfaces 50B of the plurality of boxes 50. Furthermore, the support portion 34 has an inner support portion 36 and an outer support portion 38. The support surface 35 is an example of the "support surface" and "first support surface" involved in the technology of this invention.

[0052] As an example, the inner support portion 36 is a protrusion formed by causing the base plate 16 to bulge upwards. The inner support portion 36, when viewed from above, has a rectangular shape (see reference). Figure 3 ).

[0053] As an example, the outer support portion 38 is a protrusion formed by causing the base plate 16 to bulge upwards. When viewed from above, the outer support portion 38 forms a rectangular frame shape (see reference). Figure 3 The outer support portion 38 surrounds the inner support portion 36.

[0054] 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 the "first surface" according to the technology of the present invention. The inner support surface 37 is an example of the "second surface" according to the technology of the present invention.

[0055] As an example, the outer support surface 39 is the upper surface of the outer support portion 38. When viewed from above, the outer support surface 39 forms a rectangular frame. The outer support surface 39 is located on the outer periphery of the support surface 35.

[0056] As an example, the inner support surface 37 is the upper surface of the inner support portion 36. The inner support surface 37 is rectangular in shape when viewed from above. The inner support surface 37 is planar. The inner support surface 37 is located closer to the center of the support surface 35 than the outer support surface 39. Here, "planar" means, in addition to being perfectly planar, also includes a plane within the scope of error generally permissible in the technical field to which this invention pertains and which does not depart from the technical spirit of this invention.

[0057] As an example, such as Figure 4 As shown, the inner support surface 37 is located on the side 50B of the housing 50, which is closer to the outer support surface 39. Here, "located on the side 50B of the housing 50" means that, in the lower housing 12, the inner support surface 37 is located on the upper part of the housing, which is closer to the outer support surface 39.

[0058] As an example, such as Figure 5 As shown, a step difference 40 is formed between the outer support surface 39 and the inner support surface 37. The vertical dimension H of the shell of the step difference 40 is 0.1 mm or more and 1.3 mm or less.

[0059] As an example, in the receiving area 32 of the lower housing 12, a box 50 is filled into the directional side 50A of the actuator (not shown) (see reference). Figure 1 The box is contained in an upward-facing state. In this case, the side 50B, opposite to side 50A of the box 50, is supported by the support surface 35 (see reference). Figure 4Here, the central portion 50BA of the side surface 50B of the box 50 along its length is supported by the inner support surface 37. On the other hand, the end portion (i.e., the edge portion) 50BB of the side surface 50B of the box 50 along its length is supported by contact with the outer support surface 39. For example, the outer support surface 39 supports the side surface 50B of the box 50 by contacting it when subjected to vibrations during transport. Here, the length direction of the side surface 50B corresponds to the front-rear direction of the housing when the box 50 is housed in the storage box 10.

[0060] As an example, such as Figure 4 As shown, on the lower surface of the base plate 16, a rectangular frame-shaped frame portion 42 is formed between the inner support portion 36 and the outer support portion 38 (see reference). Figure 2 ).

[0061] As an example, such as Figure 3 As shown, the inner support surfaces 37 of the two support portions 34 located further forward of the housing than the centerline CL in the front-rear direction passing through the lower housing 12 are different in size from those of the two support portions 34 located further rearward of the housing than the centerline CL. In the following description, the two support portions 34 located further forward of the housing than the centerline CL will be referred to as support portions 34A, and the two support portions 34 located further rearward of the housing than the centerline CL will be referred to as support portions 34B.

[0062] As an example, the outer size of the inner support portion 36 of support portion 34A is larger than the outer size of the inner support portion 36 of support portion 34B.

[0063] As an example, in the following text, the frame portion 42 formed on the opposite side of the support portion 34A of the base plate 16 will be referred to as frame portion 42A. Furthermore, in the following text, the frame portion 42 formed on the opposite side of the support portion 34B of the base plate 16 will be referred to as frame portion 42B. The size of frame portion 42B is such that it can be accommodated inside frame portion 42A.

[0064] As an example, such as Figure 6 As shown, the upper housing 14 has the same shape as the lower housing 12. Here, "same" means not only identical, but also includes similarity to a degree of error generally permissible in the technical field to which this invention pertains and which does not depart from the spirit of the invention. Therefore, in Figure 6 In the text, the symbols used to mark the various parts of the upper shell 14 are the same as those used to mark the various parts of the lower shell 12, except for the top plate 17 which corresponds to the bottom plate 16.

[0065] The support surface 35 of the upper housing 14 is an example of the "support surface" and "second support surface" according to the technology of the present invention. Furthermore, the outer support surface 39 of the upper housing 14 is an example of the "first surface" according to the technology of the present invention. The inner support surface 37 of the upper housing 14 is an example of the "second surface" according to the technology of the present invention.

[0066] Here, by overlapping the lower housing 12 and the upper housing 14 in a direction where the support surface 35 of the lower housing 12 and the support surface 35 of the upper housing 14 are opposite each other, a receiving chamber 11 is formed inside the storage box 10. Specifically, the upper housing 14 is placed on the lower housing 12 such that the surface of the flange portion 20 of the lower housing 12 overlaps with the surface of the flange portion 20 of the upper housing 14. Then, the lower housing 12 and the upper housing 14 are assembled by engaging the engaging protrusion 24 and engaging recess 26 of the lower housing 12 with the engaging recess 26 and engaging protrusion 24 of the upper housing 14, respectively. Here, when the lower housing 12 and the upper housing 14 are assembled with multiple boxes 50 contained in the receiving area 41 of the lower housing 12, the multiple boxes 50 are contained within the storage box 10. Thus, a package 52 containing multiple boxes 50 is completed within the storage box 10.

[0067] As an example, the lower housing 12 and the upper housing 14 are formed of a resin material. Examples of resin materials used to form the lower housing 12 and the upper housing 14 include polyethylene terephthalate (PET). In this embodiment, the lower housing 12 and the upper housing 14 are formed of polyethylene terephthalate. Furthermore, as an example, the lower housing 12 and the upper housing 14 are both integrally molded resin articles. Therefore, in this embodiment, the support surface 35 of the lower housing 12 is formed of a resin material. And, in this embodiment, the support surface 35 of the upper housing 14 is formed of a resin material.

[0068] As an example, such as Figure 7As shown, the lower surface 12A of the lower housing 12 has an overlapping surface 12B including frame portions 42A and 42B. Similarly, the upper surface 14A of the upper housing 14 has an overlapping surface 14B including frame portions 42A and 42B. Here, the overlapping surfaces 12B and 14B are shaped to overlap each other. For example, when the lower housing 12 is placed on the upper housing 14, the overlapping surface 12B of the lower housing 12 can overlap with the overlapping surface 14B of the upper housing 14. Furthermore, as an example, the lower housing 12 has an overlapping surface 12C including a support surface 35. Here, the overlapping surface 12C of the lower housing 12 and the overlapping surface 14B of the upper housing 14 are shaped to overlap each other. And, as an example, the upper housing 14 has an overlapping surface 14C including a support surface 35. Here, the overlapping surface 14C of the upper housing 14 and the overlapping surface 12B of the lower housing 12 are shaped to overlap each other. The overlapping surface 12C of the lower housing 12 is an example of the "first overlapping surface" according to the technology of the present invention. The overlapping surface 14B of the upper housing 14 is an example of the "second overlapping surface" according to the technology of the present invention.

[0069] Next, the effects of storage box 10 will be explained.

[0070] In the storage box 10, the support surface 35 of the lower housing 12 supports the side surface 50B of the box 50. The support surface 35 has an outer support surface 39 and an inner support surface 37. The inner support surface 37 is located further towards the side surface 50B than the outer support surface 39. Therefore, the side surface 50B of the box 50 is supported by the inner support surface 37. Therefore, according to this structure, for example, compared with a structure in which the entire support surface 35 supports the side surface 50B of the box 50, wear on the outer support surface 39 can be suppressed, and correspondingly, wear on the support surface 35 can be reduced. As a result, wear dust generated by wear on the support surface 35 of the lower housing 12 can be reduced.

[0071] In the storage box 10, the outer support surface 39 is located on the outer periphery side of the support surface 35, and the inner support surface 37 is located on the central side of the support surface 35, closer to the outer support surface 39. Therefore, the central portion 50BA of the side surface 50B of the box 50 is supported by the inner support surface 37. Therefore, according to this structure, for example, compared to a structure in which the end portion 50BB (i.e., the edge portion) of the side surface 50B of the box 50 is supported by the outer support surface 39, it is possible to suppress the scraping of the end portion 50BB of the box 50 against the outer support surface 39.

[0072] In the storage box 10, the support surface 35 is formed of resin material. Therefore, according to this structure, for example, compared to a structure where the support surface 35 is formed of metal material, the support surface 35 can deform relative to the box 50. As a result, the contact pressure between the box 50 and the support surface 35 can be reduced, and damage to the side surface 50B of the box 50 can be suppressed.

[0073] In the storage box 10, the inner support surface 37 is flat. Therefore, according to this structure, for example, compared to a structure where the support surface 35 is curved into an arc shape, the contact area between the inner support surface 37 and the side surface 50B of the box 50 is increased. As a result, the storage posture of the box 50 can be stabilized.

[0074] In the storage box 10, a step difference 40 is formed between the inner support surface 37 and the outer support surface 39. Furthermore, the dimension of the step difference 40 is 0.1 mm or more and 1.3 mm or less. Here, when the dimension of the step difference 40 is less than 0.1 mm, wear on the support surface 35 cannot be suppressed. On the other hand, when the dimension of the step difference 40 exceeds 1.3 mm, the balance of the box 50 deteriorates. Therefore, according to this structure, for example, compared to the case where the dimension of the step difference 40 does not satisfy 0.1 mm or more and 1.3 mm or less, it is possible to balance suppress wear on the support surface 35 and maintain the balance of the box 50.

[0075] The storage box 10 has multiple support surfaces 35. Therefore, according to this structure, for example, compared to the case where there is only one support surface 35, each of the multiple support surfaces 35 can support multiple boxes 50. Thus, multiple boxes 50 can be distributed and accommodated within the storage box 10.

[0076] In the storage box 10, the lower shell 12 and the upper shell 14 are formed of polyethylene terephthalate. Therefore, according to this structure, for example, compared with a structure in which the lower shell 12 and the upper shell 14 are formed of a resin material that easily generates abrasive powder, wear on the support surface 35 can be suppressed.

[0077] In the storage box 10, the lower shell 12 and the upper shell 14 each have a support surface 35. Therefore, according to this structure, for example, compared to a structure in which either the lower shell 12 or the upper shell 14 does not have a support surface 35, wear dust generated due to wear of the respective support surfaces 35 of the lower shell 12 and the upper shell 14 can be suppressed.

[0078] In the storage box 10, the lower housing 12 and the upper housing 14 are overlapped in a direction where their respective support surfaces 35 face each other to accommodate the box 50. The side 50B of the box 50 is then supported by the support surface 35 of the lower housing 12. Furthermore, the side 50A of the box 50 is supported by the support surface 35 of the upper housing 14. Therefore, according to this structure, for example, compared to a structure where either the lower housing 12 or the upper housing 14 does not have a support surface 35, it is possible to suppress wear dust generated by wear on the respective support surfaces 35 of the lower housing 12 and the upper housing 14.

[0079] In the storage box 10, the overlapping surfaces 12C of the lower housing 12 and 14B of the upper housing 14 overlap each other. Here, by placing the upper housing 14 in an inverted state inside the peripheral wall 18 of the lower housing 12, the overlapping surfaces 12C and 14B of the lower housing 12 overlap. Therefore, according to this structure, compared to a shape where the overlapping surfaces 12C and 12B of the lower housing 12 and upper housing 14 do not overlap, the space required for multiple overlapping lower housings 12 and upper housings 14 (e.g., the height of the multiple overlapping housings) can be reduced. Furthermore, in the storage box 10, the overlapping surfaces 12B of the lower housing 12 and 14B of the upper housing 14 overlap each other. Therefore, when another storage box 10 is loaded onto the storage box 10, the overlapping surface 14B of the lower storage box 10 overlaps with the overlapping surface 12B of the upper storage box 10. Therefore, according to this structure, for example, compared to a shape in which the overlapping surfaces 12B of the lower housing 12 and the upper housing 14 do not overlap each other, it is possible to suppress the shaking of the storage box 10 when multiple storage boxes 10 are loaded.

[0080] In the packaging 52, a plurality of boxes 50 are contained in a storage box 10, which is an example of an application of the technology involved in this invention. Therefore, according to this structure, for example, compared to a structure in which the storage box 10 supports the side surface 50B of the box 50 with the entire support surface 35, wear based on the outer support surface 39 can be suppressed, and wear on the support surface 35 can be reduced accordingly. As a result, wear dust generated by wear on the support surface 35 can be reduced.

[0081] In the above embodiments, the lower shell 12 and the upper shell 14 are formed of polyethylene terephthalate, but the technology of the present invention is not limited to this structure. For example, the lower shell 12 and the upper shell 14 may also be formed of polypropylene or polystyrene.

[0082] Furthermore, in the storage box 10, the support surface 35 of the upper shell 14 supports the side surface 50A of the box 50. Therefore, the support surface 35 of the upper shell 14 can also achieve the same effect as the support surface 35 of the lower shell 12.

[0083] In the above embodiment, the lower housing 12 and the upper housing 14 are designed to have the same shape. However, the technology of the present invention is not limited to this structure, and the shapes of the lower housing 12 and the upper housing 14 can also be different. For example, the lower housing 12 can be designed as the main body of the storage box, and the upper housing 14 can be designed as the lid of the storage box. Even in this case, by having support surfaces 35 on both the main body and the lid, the same effect as the storage box 10 in the above embodiment can be achieved.

[0084] In the above embodiment, the support surface 35 is formed of resin material, but the technology of the present invention is not limited to this structure. For example, as Figure 8As shown, a thin, soft material 60 can also be provided on the upper surface of the support portion 34. Here, the surface of the soft material 60 corresponds to the support surface 35. Examples of the soft material 60 include fabric materials such as blankets and / or cushioning materials such as sponges. In this case, compared to a structure where the support surface 35 is formed of resin material, damage to the sides of the box 50 can be suppressed.

[0085] In the above embodiment, the side surface 50B of the box 50 is straight, but the central portion 50BA of the side surface 50B can be recessed further into the inner periphery of the box 50 than the end portion 50BB of the side surface 50B. As described above, even though the shape of the side surface 50B of the box 50 is recessed into the inner periphery of the box 50, in the storage box 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 structure, for example, compared with a structure in which only the end portion 50BB (i.e., the edge portion) of the side surface 50B is supported by the outer support surface 39, it is possible to suppress the scraping of the end portion 50BB of the side surface 50B against the outer support surface 39.

[0086] In the above embodiment, an upper housing 14 is assembled on a lower housing 12, but the technology of the present invention is not limited to this structure. For example, the upper housing 14 may be used as the lower housing, and the lower housing 12 may be used as the upper housing. In this case, the upper housing 14 is an example of the "first housing component" according to the technology of the present invention. The lower housing 12 is an example of the "second housing component" according to the technology of the present invention.

[0087] In the above embodiment, the storage box 10 includes a lower shell 12 and an upper shell 14, but the technology of the present invention is not limited to this structure. For example, the storage box 10 may also be formed only by the lower shell 12.

[0088] The descriptions and illustrations above are detailed explanations of the parts related to the technology of this invention, and are merely one example of the technology of this invention. For example, the descriptions related to the above-described structure, function, effect, and effect are examples of the structure, function, effect, and effect of the parts related to the technology of this invention. Therefore, without departing from the technical spirit of this invention, unnecessary parts may be deleted from the descriptions and illustrations above, or new elements may be added or replaced. Furthermore, to avoid complications and to facilitate understanding of the parts related to the technology of this invention, descriptions related to common technical knowledge that are not particularly necessary to explain in terms of enabling the implementation of this invention have been omitted from the descriptions and illustrations above.

[0089] In this specification, "A and / or B" has the same meaning as "at least one of A and B". That is, "A and / or B" can mean only A, only B, or a combination of A and B. Furthermore, in this specification, the same approach applies to situations where three or more cases are connected by "and / or".
