[0024] According to the description and accompanying drawings described below, at least the following manner becomes clear.

[0025] Method 1 is a packaging unit characterized by comprising: a wire; and a packaging body that houses the wire, wherein the packaging body is deformable into a first form for packaging the wire and a second form for extracting the wire, wherein in the second form, the extraction port for extracting the wire from the packaging body is located at a position higher than the uppermost part of the packaging body in the first form. Thus, the wire extraction performance can be improved without the need for structures such as arms.

[0026] Method 2 is a packaging unit completed based on the packaging unit of Method 1, characterized in that the packaging body has a retaining portion protruding upward from the bottom surface of the packaging body. The presence of such a retaining portion is particularly effective.

[0027] Method 3 is a packaging unit completed based on the packaging unit of Method 2, characterized in that the distance from the bottom surface to the extraction port in the second form is at least 1.5 times the distance from the bottom surface to the front end of the holding part. This allows for easy extraction of the wire.

[0028] Method 4 is a packaging unit completed based on the packaging unit of Method 2 or 3, characterized in that the aforementioned holding part is fixed at two points spaced apart in the vertical direction. Thus, the holding part becomes a structure that is not easily tipped over.

[0029] Method 5 is a packaging unit completed based on any one of the packaging units in methods 1 to 4, characterized in that the packaging body has multiple lids, and in the second embodiment, the drawer outlet is disposed on a cover portion assembled from the lids. Thus, the drawer outlet can be positioned at a high position using the lids.

[0030] Method 6 is a packaging unit completed based on the packaging unit of Method 5, characterized in that the cylindrical component constituting the aforementioned drawout is provided at the portion connecting to the aforementioned cover. This prevents the wire from entering the portion connecting to the cover.

[0031] Method 7 is a packaging unit completed based on the packaging unit of Method 5 or 6, characterized in that the cover has a connecting portion, which is joined with other components during the assembly of the cover. This increases the strength of the cover.

[0032] Method 8 is a packaging unit completed based on the packaging unit of Method 7, characterized in that the aforementioned joint has protrusions and recesses, which can be engaged by the opening and closing action of the cover. This simplifies the assembly of the cover.

[0033] Method 9 is a packaging unit completed based on any one of the packaging units in methods 1 to 4, characterized in that it includes: a movable body having the aforementioned draw-out port; and a telescopic member for raising and lowering the movable body. Thus, the draw-out port can be positioned at a higher position by extending the telescopic member.

[0034] Method 10 is a packaging unit completed based on the packaging unit of Method 9. Its characteristic is that the packaging body has a retaining portion protruding upwards from the bottom surface, and in the first configuration, the movable body is positioned below the front end of the retaining portion. This prevents the wire from detaching from the retaining portion in the first configuration.

[0035] Method 11 is a packaging unit completed based on the packaging unit of Method 10, characterized in that, in the first configuration described above, the moving body contacts the upper surface of the wound body formed by winding the wire. This prevents the wound body from collapsing.

[0036] ===First Implementation Method===

[0037] Figure 1A and Figure 1B This is an explanatory diagram of the packaging unit 1 according to the first embodiment. Figure 1A This is an explanatory diagram of the first type of packaging unit 1. Figure 1B This is an explanatory diagram of the second type of packaging unit 1. Figure 2A and Figure 2B This is an explanatory diagram of the interior of packaging unit 1. Figure 2A This is an explanatory diagram showing the interior of packaging unit 1 as viewed from the side. Figure 2B This is an explanatory diagram showing the interior of the packaging unit 1 without illustrating the side panel 412 and the cover 42.

[0038] In the following description, the direction perpendicular to the bottom surface of the packaging body 40 (the upper surface of the bottom 411; the surface supporting the winding body 20) is defined as the "vertical direction," and the side of the winding body 20 viewed from the bottom surface of the packaging body 40 is defined as "upper," and the opposite side is defined as "lower." When the packaging unit 1 is placed on a horizontal plane, the vertical direction is consistent with the vertical direction. Additionally, in the following description, the direction perpendicular to the vertical direction is sometimes referred to as the horizontal direction.

[0039] Packaging unit 1 is a component (unit) that packages the wire 10. For example... Figure 1A and Figure 1B As shown, packaging unit 1 can deform into different shapes. Figure 1A As shown, the form used for packaging wire 10 is referred to as the "first form". For example... Figure 1B As shown, the configuration for extracting the wire 10 is referred to as the "second configuration". The packaging unit 1 includes the wire 10, the packaging body 40, and the tray 60.

[0040] The wire 10 is a linear component. The wire 10 may include, for example, cables (electrical wires, optical fibers, etc.), wires, tubes, etc. Here, the wire 10 is an optical fiber. The wire 10 is packaged in a bent state. Here, the wire 10 is packaged in a wound state. For example, a rigid, thick cable with an outer diameter of 3 mm or more can be wound for more than 1000 m and then stored in the package 40 in a pull-out manner. Furthermore, when the outer diameter of the cable is 7 to 11 mm, a cable with a length of 2000 m can be stored in a package 40 measuring 1 m × 1 m × 1 m. In the following description, the structure formed by winding the wire 10 is sometimes referred to as a "wound body". However, the wire 10 may also be packaged without being wound.

[0041] Figure 3A This is an illustrative diagram of an example of a wound body 20. Figure 3B This is an illustrative diagram of another example of a wound body. The wound body 20 is constructed by repeatedly reversing the winding direction while winding the wire 10. By repeatedly reversing the winding direction of the wire 10, thus achieving... Figure 1B When the wire 10 is pulled out from the winding body 20, the twisting of the wire 10 can be suppressed. The winding body 20 has a reversing section 22 that alternately stacks wire 10 wound into an S-shape and wire 10 wound into an inverted S-shape. Figure 3A The winding body 20 shown has a wrapping portion 21 that allows the wire 10 to wrap around the outer periphery of the reversing portion 22. Furthermore, as... Figure 3B As shown, the winding body 20 may also omit the wrapping portion 21. Furthermore, the winding body 20 may be configured to wind the wire 10 without reversing the winding direction. The structure of the winding body 20 can be appropriately modified according to requirements.

[0042] The packaging body 40 is a structure for packaging the wire 10 (wound body 20). The packaging body 40 has a receiving space for accommodating the wire 10 (wound body 20). The packaging body 40 can be deformed into a first form and a second form. Here, the packaging body 40 is configured as a box. However, the packaging body 40 is not limited to a box-shaped structure, and can also be a skeleton-shaped (frame-like) structure. That is, the packaging body 40 has components that form the receiving space. For example, the components that form the receiving space can be components covering the bottom, sides, and top surface of the receiving space, or it can be a skeleton. The materials of the components that form the receiving space can be, for example, wood, corrugated paper and other paper, metal, FRP, plastic, and combinations thereof. In particular, when the components that form the receiving space are made of corrugated paper, it is lightweight, easy to disassemble, and has excellent reusability, and does not use preservatives or other chemicals, so it is more suitable for contributing to a sustainable society than metal or wooden drums. The packaging body 40 of the first embodiment has a main body 41 and a cover 42. However, as will be described later, the packaging body 40 may also be without a lid.

[0043] The main body 41 is the part that constitutes the main body of the packaging body 40. The main body 41 is the part that packages the wire 10 (winding body 20). The main body 41 has a bottom 411 and a holding part 413.

[0044] The bottom 411 forms the bottom of the main body 41. The bottom 411 serves as a component that supports the winding body 20 from below. Here, the bottom 411 is a plate-shaped component, but it is not limited to a plate-shaped component as long as it can support the winding body 20.

[0045] Side panels 412 are provided, rising upwards from the periphery of the bottom 411. The side panels 412 form the sides of the main body 41. However, if the main body 41 is configured as a skeleton, it may not have side panels 412. Furthermore, here, the bottom 411 and multiple (here, four) side panels 412 form a storage space for accommodating the wire 10. The number of side panels 412 is not limited to four; for example, it could be six, eight, or so on.

[0046] The retaining part 413 is a component that holds the wire 10 in a wound shape. In other words, the retaining part 413 is a component that holds the wound body 20. The retaining part 413 is a rod-shaped (cylindrical) component along the vertical direction. The retaining part 413 extends upward from the bottom 411. The wire 10 contacts the retaining part 413 to restrict the movement of the wire 10, thereby preventing the wound body 20 from collapsing when the wire 10 is pulled out (e.g., during packaging, extraction, storage, or transportation). However, the retaining part 413 can be provided only as needed, or it may be omitted.

[0047] Using the example shown in Figure 3, a pair of retaining portions 413 are disposed near the front and rear of the reversing portion 22 of the winding body 20, respectively. Furthermore, in order to suppress the twisting of the wire 10 when it is pulled out, the winding body 20 has a reversing portion 22 that reverses the winding direction of the wire 10 to an S-shape or an inverted S-shape (Z-shape). In this reversing portion 22, the posture of the wire 10 becomes unstable and prone to collapse. Therefore, by distributing a pair of retaining portions 413 near the front and rear of the reversing portion 22 (in other words, by distributing the reversing portion 22 of the winding body 20 between a pair of retaining portions 413), the shape collapse of the reversing portion 22 can be suppressed.

[0048] The cover 42 is the part that covers the main body 41. The cover 42 is configured to be openable and closable. Figure 1A As shown, with the cover 42 closed (the cover 42 is folded), the cover 42 covers the top of the main body 41, and the packaging body 40 is in its first form (the form used to package the coil 20 in the packaging body 40). When the wire 10 is pulled out from the packaging body 40, as... Figure 1B As shown, the cover 42 is unfolded, and the cover 42 is used to assemble the cover portion 42A. The configuration with the cover portion 42A assembled corresponds to the second configuration of the package body 40 (the configuration for pulling out the wire 10).

[0049] The cover portion 42A is a part assembled from the cover 42 (the plurality of cover portions 421 described later). The cover portion 42A is disposed above the main body portion 41 and is disposed at a position higher than the uppermost part of the packaging body 40 in the first form (the highest position of the packaging body 40; in this case, the upper surface of the cover 42). A drawer outlet 43 is provided at the top of the cover portion 42A. Thus, the drawer outlet 43 can be disposed at a high position. However, the drawer outlet 43 only needs to be disposed at a position higher than the uppermost part of the packaging body 40 in the first form, and it may not be disposed at the top of the cover portion 42A. For example, the drawer outlet 43 may also be disposed on the inclined surface of the cover portion 42A.

[0050] The drawout 43 is the part from which the wire 10, packaged in the main body 41, is pulled out. The drawout 43 is set to be larger than the cross-section of the wire 10, so that the wire 10 can be inserted through the drawout 43 and pulled out to the outside. The drawout 43 is provided at a position higher than the uppermost part of the packaging body 40 in the first embodiment. In the first embodiment, the drawout 43 is provided in the cover portion 42A formed by the cover 42. However, the drawout 43 may not be provided in the cover portion 42A, or may not be provided in the cover 42 (for example, see the second embodiment described later).

[0051] like Figure 1B As shown, the cover 42 has two cover portions 421 (a first cover portion 421A and a second cover portion 421B). The first cover portion 421A is a plate-shaped component, disposed on the upper edge (top) of the side plate portion 412, and rotates (opens and closes) about the upper edge of the side plate portion 412. The second cover portion 421B is a plate-shaped component, disposed on the upper edge of the side plate portion 412 opposite to the side plate portion 412 on which the first cover portion 421A is disposed, and rotates (opens and closes) about the upper edge of the side plate portion 412. Figure 1A As shown, in the first configuration, the first cover portion 421A and the second cover portion 421B overlap and cover the top of the main body portion 41. Figure 1B As shown, in the second configuration, a herringbone-shaped roof-like cover 42A is assembled from the cover 42 (first cover 421A and second cover 421B). In the second configuration, the end edges of the first cover 421A and the second cover 421B are connected to each other, thereby stabilizing the posture of the first cover 421A and the second cover 421B.

[0052] In the first embodiment, the extraction port 43 is provided in the cover portion 42A. Here, as... Figure 1BAs shown, a cylindrical member 44 is installed at the center of the end edges of the first cover portion 421A and the second cover portion 421B, and this cylindrical member 44 constitutes a drawout port 43. That is, the cylindrical member 44 is provided at the location connecting the first cover portion 421A and the second cover portion 421B. In addition, a recess is pre-provided at the center of the end edges of the first cover portion 421A and the second cover portion 421B, and the cylindrical member 44 is installed at the opening formed by the recess. By installing the cylindrical member 44 at the location connecting the first cover portion 421A and the second cover portion 421B, it is possible to prevent the wire 10 from entering between the first cover portion 421A and the second cover portion 421B. However, the drawout port 43 may not be constituted by the cylindrical member 44 (described later; see reference). Figure 5B ).

[0053] Next, the reasons for setting the extraction outlet 43 in a high position will be explained. Figure 4 This is a schematic diagram of the wire 10, the holding part 413, and the drawout 43.

[0054] When viewed from the side, the packaging unit 1 has a pair of retaining portions 413 arranged symmetrically. That is, the pair of retaining portions 413 are arranged at equal distances from the center of the packaging body 40 (refer to the dotted line in the diagram). Here, the distance between the outer edges of the pair of retaining portions 413 is set to X. The drawout 43 is located on the extension line of the center of the packaging body 40 (refer to the dotted line in the diagram). Therefore, the lateral distance between the outer edge of the retaining portion 413 and the drawout 43 is X / 2. In addition, the distance from the bottom surface of the packaging body 40 (the upper surface of the bottom 411) to the front end of the retaining portion 413 (the protruding length of the retaining portion 413 from the bottom surface; the height of the retaining portion 413) is set to Y. In addition, the distance from the bottom surface of the packaging body 40 (the upper surface of the bottom 411) to the drawout 43 (the height of the drawout 43) is set to Z.

[0055] In order for the wire 10, which has been pulled out of the winding body 20, to be pulled out from the extraction port 43, it needs to pass over the front end of the holding part 413. Here, when the wire 10 passes over the front end of the holding part 413, the angle between the wire 10 above the front end of the holding part 413 (the wire 10 between the front end of the holding part 413 and the extraction port 43) and the lateral direction is set as θ1, and the angle between the wire 10 below the front end of the holding part 413 (the wire 10 guided by the holding part 413; the wire 10 between the winding body 20 and the front end of the holding part 413) and the lateral direction is set as θ2. The figure shows the state when the angle θ2 is at its maximum. The angle θ2 is at its maximum when the wire 10 at the bottom 411 is pulled out. Therefore, the maximum value of angle θ2 is equivalent to the angle between the line connecting the outer edge of the front end of one retaining part 413 and the outer edge of the base end (fixed end of retaining part 413 and bottom 411) of the other retaining part 413 and the bottom surface (upper surface of bottom 411) of the packaging body 40.

[0056] The larger the angle θ1, the easier it is for the wire 10 to pass the front end of the holding part 413. Therefore, it is preferable that the height Z of the drawout 43 is as large as possible. That is, it is preferable that the drawout 43 is provided at a high position. For this reason, the drawout 43 of this embodiment is provided at a position higher than the uppermost part of the packaging body 40 in the first form (the upper surface of the cover 42 in the first embodiment) (see reference). Figure 1B ).

[0057] Furthermore, the larger the angle θ1 is compared to the angle θ2, the easier it is for the wire 10 to pass over the front end of the holding part 413. Therefore, it is preferable that the angle θ1 is greater than or equal to the angle θ2. Figure 4 As shown, when the height Z of the extraction port 43 is 1.5 times the height Y of the holding part 413, the maximum values ​​of angles θ1 and θ2 are equal. Therefore, it is preferable that the height Z of the extraction port 43 is 1.5 times or more the height Y of the holding part 413.

[0058] like Figure 4 As shown, the wire 10 needs to pass over the front end of the retaining portion 413, so it is preferable that the front end of the retaining portion 413 has a shape that the wire 10 can easily pass over. Therefore, the retaining portion 413 can also be a shape that becomes thinner towards the front end. In addition, the front end of the retaining portion 413 can also have rounded corners when viewed from the side.

[0059] Furthermore, the main body 41 may not have the retaining part 413. Even if the main body 41 does not have the retaining part 413, if the drawout 43 is provided at a high position, the angle between the center line of the drawout 43 and the wire 10 can be reduced, and the wire 10 can be easily drawn out from the drawout 43. Therefore, even if the main body 41 does not have the retaining part 413, it is advantageous to provide the drawout 43 at a high position, and it is preferable that the drawout 43 is provided at a position higher than the uppermost part of the packaging body 40 in the first form.

[0060] The pallet 60 is a component that serves as the base of the packaging body 40. The pallet 60, for example, serves as a platform used when moving the packaging unit 1 with a forklift. The pallet 60 may also have a lower plate portion 61 and a spacer 62. The lower plate portion 61 is a plate-like portion forming the lower surface of the pallet 60. The spacer 62 is a component disposed between the packaging body 40 (bottom 411) and the lower plate portion 61. The spacer 62 forms a gap between the bottom 411 and the lower plate portion 61, into which the forklift forks are inserted. Alternatively, the lower plate portion 61 may be omitted, and only the spacer 62 forms a gap on the underside of the packaging body 40. The packaging unit 1 may also be without the pallet 60.

[0061] like Figure 2AAs shown, the retaining part 413 penetrates the bottom 411 of the packaging body 40, and the lower end of the retaining part 413 is fixed to the lower plate 61 of the tray 60. The retaining part 413 is fixed at both the bottom 411 of the packaging body 40 and the lower plate 61 of the tray 60. The bottom 411 and the lower plate 61 are separated by a gap in the vertical direction through the separator 62, so the retaining part 413 is fixed at two gaps in the vertical direction. Thus, the retaining part 413 has a structure that is not easy to tip over. However, the retaining part 413 may not penetrate the bottom 411 of the packaging body 40, and the lower end of the retaining part 413 may be fixed to the bottom 411 of the packaging body 40.

[0062] <Variation Example>

[0063] Figure 5A and Figure 5B This is an explanatory diagram of a first variation of the packaging unit 1 of the first embodiment. Figure 5A This is a diagram of packaging unit 1 with the lid 42 open, viewed from above. Figure 5B This is an explanatory diagram of the second type of packaging unit 1.

[0064] In the first modification, the cover 42 also has a first cover portion 421A and a second cover portion 421B, with a recess provided at the center of the end edges of the first cover portion 421A and the second cover portion 421B. In the first modification, after assembling the first cover portion 421A and the second cover portion 421B to form the cover portion 42A, the cylindrical member 44 is not installed in the recess, but the drawout 43 is formed by the recess of the first cover portion 421A and the second cover portion 421B. In this way, the drawout 43 may not be formed by the cylindrical member 44.

[0065] Figure 6A and Figure 6B This is an explanatory diagram of a second variation of the packaging unit 1 of the first embodiment.

[0066] In the second modification, the cover 42 also has a first cover portion 421A and a second cover portion 421B. In this second modification, a connecting portion 422 is provided at the end edges of the first cover portion 421A and the second cover portion 421B. The connecting portion 422 is the part where the cover portion 42A is joined with other components during assembly. The connecting portion 422 of the first cover portion 421A and the connecting portion 422 of the second cover portion 421B are joined, thereby stabilizing the posture of the first cover portion 421A and the second cover portion 421B and increasing the strength of the cover portion 42A.

[0067] Here, the joint 422 is configured with a concave-convex shape, and the concave-convex shape of the first cover 421A and the second cover 421B engages with each other, thereby joining the end edges of the first cover 421A and the second cover 421B together. However, the joint 422 is not limited to a concave-convex shape. For example, the joint of one of the first cover 421A and the second cover 421B can be configured as an insert piece, and the joint of the other can be configured as a slit. By inserting the insert piece into the slit, the end edges of the first cover 421A and the second cover 421B can be joined together. However, in cases such as Figure 6A and Figure 6B When the connecting portion 422 is configured as a concave-convex shape, the connecting portion 422 of the first cover portion 421A and the connecting portion 422 of the second cover portion 421B can be connected by the opening and closing action of the first cover portion 421A and the second cover portion 421B. Therefore, there is no need for an action such as inserting an insert piece into the slit, thus making the assembly operation of the cover portion 42A easier.

[0068] Figure 7A and Figure 7B This is an explanatory diagram of a third variation of the packaging unit 1 of the first embodiment.

[0069] In the third variation, the cover 42 also has a first cover portion 421A and a second cover portion 421B. Furthermore, in the third variation, the cover 42 has a wing portion 423. The wing portion 423 is a plate-shaped portion that seals the gap in the cover portion 42A. The wing portion 423 is provided on the upper edge (upper side) of the side plate portion 412 where neither the first cover portion 421A nor the second cover portion 421B is provided, and rotates (opens and closes) about the upper edge of the side plate portion 412. When assembling the herringbone-shaped cover portion 42A using the first cover portion 421A and the second cover portion 421B, the side edges of each of the first cover portion 421A and the second cover portion 421B are connected to the side edge of the wing portion 423. Thus, the wing portion 423 can seal the side gaps of the herringbone-shaped cover portion 42A. Furthermore, in the third modification, as in the second modification with joint 422, joints can be provided on the side edges of the first cover 421A and the second cover 421B, and on the side edges of the wing 423, respectively, so that the joint of the first cover 421A or the second cover 421B is joined to the joint of the wing 423. This increases the strength of the cover 42A.

[0070] Figure 8A and Figure 8B This is an explanatory diagram of a fourth variation of the packaging unit 1 of the first embodiment.

[0071] In the fourth variation, the cover 42 has a plurality of (here, four) cover portions 421. Each cover portion 421 is provided on the upper edge (top) of each of the plurality of side plate portions 412 of the main body portion 41. By connecting the side edges of the four cover portions 421 to each other, a square roof-shaped (frustum-shaped) cover portion 42A is assembled. In the fourth variation, the end edges of the plurality of cover portions 421 form a drawout 43. Alternatively, a cylindrical member 44 may be installed in the opening formed by the end edges of the plurality of cover portions 421, thereby forming the drawout 43. By forming the drawout 43 with the cylindrical member 44, it is possible to prevent the wire 10 from entering between the cover portions 421. Furthermore, in the fourth variation, as in the second variation with the connecting portion 422, a connecting portion may be provided on the side edge of each cover portion 421, so that the connecting portions of the cover portions 421 are joined together. As a result, the strength of the cover portion 42A is increased.

[0072] Figure 9A and Figure 9B This is an explanatory diagram of the fifth variation of the packaging unit 1 of the first embodiment.

[0073] In the fifth variation, at the point where a recess 424 is formed on the end edge of the cover portion 421 constituting the extraction port 43, the recess 424 is located, which is the same as in the fourth variation ( Figure 8A and Figure 8B The difference is that a recess 424 is formed at the end edge of the cover 421, thereby arranging the recess 424 around the periphery of the drawout 43. When the wire 10 is drawn out from the drawout 43, the wire 10 enters the recess 424, thereby stabilizing the position of the drawn wire 10 in the position of the recess 424. In the fifth variation, the wire 10 can be prevented from entering between the cover portions 421 without using the cylindrical component 44.

[0074] Figure 10A and Figure 10B This is an explanatory diagram of the sixth variation of the packaging unit 1 of the first embodiment.

[0075] In the sixth variation, the cover 42 also has multiple (here, four) cover portions 421. Each cover portion 421 has an upper surface portion 425. The upper surface portion 425 is a plate-like portion that forms the upper surface of the cover portion 42A. The upper surface portion 425 is provided on the end edge of the cover portion 421 on the side opposite to the side plate portion 412. A hole 425A is formed in the upper surface portion 425, and the hole 425A forms the drawout 43. Here, the upper surface portion 425 is provided in each of the four cover portions 421, and the four upper surface portions 425 overlap to form the upper surface of the cover portion 42A. However, it is sufficient to provide an upper surface portion 425 in at least one cover portion 421. According to the sixth variation, it is possible to prevent the wire 10 from entering between the cover portions 421.

[0076] In the first embodiment, which includes the first to sixth variations described above, the drawout 43 in the second form is located at a higher position than the uppermost part of the packaging body 40 in the first form. Therefore, by modifying the packaging unit 1, the drawout 43 can be positioned at a higher position, thus allowing the wire 10 to be easily drawn out with a simple structure.

[0077] Furthermore, in the first embodiment, which includes the first to sixth variations described above, the packaging body 40 has a plurality of cover portions 421, and the drawout 43 is provided in the cover portion 42A assembled from the cover portions 421. Thus, the drawout 43 can be positioned at a high position using the cover 42, thereby improving the drawability of the wire without the need for structures such as arms.

[0078] <Experimental Example>

[0079] Production Figure 1A and Figure 1B The packaging unit 1 shown was used to evaluate the pull-out performance of the optical cable (equivalent to wire 10). Here, packaging unit 1 was manufactured with a distance of 700 mm between the pair of retaining parts 413, a height Y of 720 mm for the retaining parts 413, and a height Z of the pull-out port 43 varying from 810 mm to 1500 mm. Furthermore, the diameter of the optical cable was 7 mm. In the evaluation of pull-out performance, a good rating (○) was given when the optical cable was pulled out of the pull-out port 43 without excessive force; a satisfactory rating (△) was given when the optical cable was pulled out of the pull-out port 43 only with strong force; and a non-satisfactory rating (×) was given when the optical cable could not be pulled out at all.

[0080] Table 1 shows the evaluation results of the extraction performance of each packaging unit 1 with different extraction port heights Z.

[0081] [Table 1]

[0082]

[0083] △: Only strong pulling can pull the optical cable out.

[0084] ○: The fiber optic cable was pulled out without excessive force.

[0085] As shown in Table 1, when the height Z of the pull-out port 43 is more than 1.5 times the height Y of the holding part 413, the optical cable can be pulled out of the pull-out port 43 without excessive force. Thus, it has been confirmed that as long as the height Z of the pull-out port 43 is more than 1.5 times the height Y of the holding part 413, the cable 10 can easily pass over the front end of the holding part 413. Furthermore, even when Z / Y = 1.46, the optical cable can be pulled out of the pull-out port 43. Thus, even if the height Z of the pull-out port 43 is less than 1.5 times the height Y of the holding part 413, the optical cable can be pulled out of the pull-out port 43 as long as it can resist the optical cable from hooking onto the holding part 413. However, it has been confirmed that as long as the height Z of the pull-out port 43 is more than 1.5 times the height Y of the holding part 413, it is possible to pull out the optical cable without resisting it from hooking onto the holding part 413, thus making it easier to pull out compared to the case where the height Z of the pull-out port 43 is less than 1.5 times the height Y of the holding part 413. Furthermore, as... Figure 4 As shown, considering that as long as the height Z of the pull-out 43 is more than 1.5 times the height Y of the holding part 413, the wire 10 can easily pass over the front end of the holding part 413, in relation to... Figure 1A and Figure 1B In the case of different packaging units 1 shown, it is also the same as Figure 1A and Figure 1B Similarly, in the packaging unit 1 shown, if the height Z of the extraction port 43 is more than 1.5 times the height Y of the holding part 413, it becomes easier to extract the contents compared to the case where the height Z of the extraction port 43 is less than 1.5 times the height Y of the holding part 413.

[0086] ===Second Implementation Method===

[0087] Figure 11A and Figure 11B This is an explanatory diagram of the packaging unit 1 according to the second embodiment. Figure 11A This is an explanatory diagram of the first type of packaging unit 1. Figure 11B This is an explanatory diagram of the second type of packaging unit 1. Figures 12A-12C This is an explanatory diagram of the lifting unit 50. Figure 12A This is a view of packaging unit 1 from above. Figure 12B This is an explanatory diagram of the lifting unit 50 in the first configuration. Figure 12C This is an explanatory diagram of the lifting unit 50 in its second configuration. Furthermore, in Figure 12B and Figure 12C In order to show the lifting unit 50 (and the winding body 20), the side plate portion 412 is not shown.

[0088] In the second embodiment, the packaging unit 1 also includes a winding body 20, a packaging body 40, and a tray 60. Furthermore, in the second embodiment, the lifting unit 50 may not include the tray 60. The packaging body 40 of the second embodiment also includes the lifting unit 50. Additionally, the packaging body 40 of the second embodiment may or may not include a lid 42, similar to the first embodiment.

[0089] The lifting unit 50 is a component that raises and lowers the drawer outlet 43. When the packaging body 40 is in its first configuration (for packaging the coil 20 within the packaging body 40), the lifting unit 50 lowers the drawer outlet 43 and is housed within the packaging body 40 (main body 41). Furthermore, when the packaging body 40 is equipped with a cover 42, with the lifting unit 50 lowering the drawer outlet 43, closing the cover 42 (not shown) allows the lifting unit 50 to be packaged within the packaging body 40. When the packaging body 40 is in its second configuration (for drawing out the wire 10), the lifting unit 50 raises the drawer outlet 43, placing it at a position higher than the uppermost part of the packaging body 40 in the first configuration (the highest position of the packaging body 40; the upper surface of the cover 42 if present; the upper edge of the main body 41 if not present). Furthermore, when the packaging body 40 is equipped with a lid 42, when the packaging body 40 is transformed from the first form to the second form, after the lid 42 is opened, the lifting unit 50 is used to position the drawout 43 at a high position.

[0090] The lifting unit 50 has: a movable body 51 having an outlet 43; and a telescopic component 52.

[0091] The movable body 51 is a component that moves (lifts and lowers) in the vertical direction. When the packaging body 40 is in its first form (the form for packaging the wire 10), the movable body 51 is in a lowered position and is packaged within the main body 41. When the packaging body 40 is in its second form (the form for pulling out the wire 10), the movable body 51 is in a raised position, becoming a position higher than the uppermost part of the packaging body 40 in the first form. The movable body 51 has a pull-out port 43 and a connecting portion 511. In the second embodiment, the pull-out port 43 is provided on the movable body 51, but not on the cover 42 of the packaging body 40. The connecting portion 511 is the part that connects the pull-out port 43 to the telescopic member 52. One end of the connecting portion 511 is connected to the pull-out port 43, and the other end of the connecting portion 511 is connected to the telescopic member 52 (specifically, the front end of the telescopic member 52). Figures 12A-12C The drawout 43 and connecting portion 511 shown are constructed from the same component (rod-shaped component). However, the component constituting the drawout 43 and the component constituting the connecting portion 511 may also be constructed from different components (described later; see reference). Figure 14C ).

[0092] like Figure 11A As shown, when the packaging body 40 is in its first configuration (the configuration for packaging the wire 10), the movable body 51 is positioned lower than the front end of the holding portion 413. This prevents the wire 10 of the winding body 20 from detaching from the holding portion 413 in the first configuration. However, in the first configuration, the movable body 51 can also be positioned higher than the holding portion 413 (but lower than the uppermost part of the packaging body 40 in the first configuration).

[0093] In addition, such as Figure 11A As shown, when the packaging body 40 is in its first configuration (the configuration for packaging the wire 10), the movable body 51 contacts the upper surface of the winding body 20 (contacts the wire 10 constituting the upper surface of the winding body 20). Therefore, in the first configuration, the wire 10 of the winding body 20 can be pressed down, thereby preventing the winding body 20 from collapsing. However, even if the movable body 51 does not contact the wire 10 of the winding body 20, as long as the movable body 51 is positioned lower than the front end of the holding portion 413, the wire 10 of the winding body 20 can be prevented from detaching from the holding portion 413.

[0094] The telescopic member 52 is a member that extends and retracts in the vertical direction. The telescopic member 52 is a member that causes the movable body 51 to move (lift / lower) in the vertical direction. The telescopic member 52 is a member extending vertically and upwards from the bottom 411. In the figure, the lower end of the telescopic member 52 is fixed to the bottom 411. However, similar to the aforementioned retaining part 413, the telescopic member 52 can also penetrate the bottom 411 of the packaging body 40, and the telescopic member 52 is fixed at both the bottom 411 and the lower plate part 61 of the tray 60. Thus, the telescopic member 52 has a structure that prevents it from tipping over. The movable body 51 (specifically, the connecting part 511) is fixed to the upper end of the telescopic member 52. By extending and retracting the telescopic member 52, the movable body 51 moves (lifts / lowers) in the vertical direction. Multiple telescopic members 52 are arranged on the outside of the winding body 20, arranged circumferentially at intervals to surround the winding body 20. Here, four telescopic members 52 are arranged at 90-degree intervals on the outer periphery of the winding body 20.

[0095] Figure 13 This is an explanatory diagram illustrating an example of the construction of the telescopic component 52.

[0096] The telescopic member 52 has an upper member 521, a lower member 522, and a fixing part 523. The upper member 521 and the lower member 522 are members along the vertical direction. The upper member 521 slides upward relative to the lower member 522, thereby extending the telescopic member 52. Alternatively, the telescopic member 52 can be extended by connecting the upper member 521 and the lower member 522 with a hinge and widening the hinge angle (in other words, by unfolding the folded upper member 521 and the lower member 522), instead of allowing the upper member 521 and the lower member 522 to slide. The telescopic member 52 can also be multi-stage. Figure 13 The structure shown allows for multi-stage telescoping. Here, the upper part 521 and the lower part 522 are cylindrical, with the outer diameter of the upper part 521 being smaller than the inner diameter of the lower part 522. The upper part 521 is positioned inside the lower part 522. A fixing part 523 fixes the upper part 521 and the lower part 522, and remains fixed even when the telescoping member 52 is extended. The fixing part 523 shown in the figure is provided on the upper part 521 and has a protrusion that is spring-loaded outward. If the upper part 521 moves upward relative to the lower part 522, the protrusion of the fixing part 523 enters the fitting hole of the lower part 522, thereby fixing the upper part 521 and the lower part 522. Preferably, the fixing part 523 is a structure that automatically fixes the upper part 521 and the lower part 522 when the upper part 521 is moved relative to the lower part 522 to a predetermined position. Therefore, for example, compared to fixing the upper part 521 and the lower part 522 with screws, it is easier to perform the fixing operation when the telescopic member 52 is extended. In particular, when multiple telescopic members 52 need to be extended simultaneously when the movable body 51 (exit port 43) is raised, if the fixing part 523 is configured to automatically fix the upper part 521 and the lower part 522, it is easier to perform the fixing operation when the movable body 51 (exit port 43) is raised.

[0097] Furthermore, the fixing part 523 is not limited to Figure 13 The structure shown is as follows. For example, the fixing part may be provided on the lower part 522 and have a protrusion that is applied inward. The protrusion of the fixing part enters the fitting hole of the upper part 521, thereby fixing the upper part 521 and the lower part 522. In addition, the fixing part 523 is not limited to Figure 13The structure uses a spring to apply force to the protrusion as shown. For example, a tapered shape can be provided on the outer surface of the upper component 521 and the inner surface of the lower component 522. The upper component 521 moves upward relative to the lower component 522, thereby engaging the outer surface of the upper component 521 with the inner surface of the lower component 522, and fixing it in the extended state of the telescopic component 52. Even with such a structure where the tapered surfaces engage, the upper component 521 and the lower component 522 can be automatically fixed when the upper component 521 moves relative to the lower component 522 to a predetermined position. However, the fixing part 523 is not limited to a structure that automatically fixes the upper component 521 and the lower component 522. For example, the upper component 521 and the lower component 522 can also be fixed by screws, pins, locking rods, etc. In addition, the upper component 521 and the lower component 522 are not limited to cylindrical components. For example, they can also be made of rod-shaped or plate-shaped components. In addition, the fixing part 523 may not be equipped on the lifting unit 50 itself. However, if the lifting unit 50 has a fixing part 523, it is easier to fix it when the telescopic member 52 is extended.

[0098] Figures 14A-14C This is an explanatory diagram of a modified example of the lifting unit 50.

[0099] Figure 14A The lifting unit 50 of the first modified example shown has a movable body 51 and telescopic members 52. Four telescopic members 52 are arranged at 90-degree intervals around the outer periphery of the winding body 20. The movable body 51 has two intersecting bridging portions 512. Each bridging portion 512 is located between the front ends of two opposing telescopic members 52. Each bridging portion 512 is composed of a pair of parallel rod members. The intersection of the two bridging portions 512 forms an outlet 43, and the remaining portion forms a connecting portion 511.

[0100] exist Figure 14B In the second variation shown, the lifting unit 50 also includes a movable body 51 and telescopic members 52. In this second variation, the lifting unit 50 has two telescopic members 52, and a bridging portion 512 is provided such that the front ends of the two telescopic members 52 are positioned relative to each other. In this second variation, a drawout 43 is formed at the center of the bridging portion 512, and a connecting portion 511 is formed at the other portion. As shown in the second variation, the telescopic members 52 may also be arranged on the outer periphery of the winding body 20 without being spaced 90 degrees apart.

[0101] exist Figure 14CIn the third variation shown, the lifting unit 50 also has a movable body 51 and a telescopic member 52. The movable body 51 in the third variation has a drawout 43 composed of a ring member 513, and a rope member (equivalent to a connecting part 511) connecting the drawout 43 (ring member 513) and the telescopic member 52. In this way, the drawout 43 and the connecting part 511 may not be composed of rod-shaped members.

[0102] In the second embodiment, which includes the first to third variations described above, similar to the first embodiment, the drawout 43 in the second embodiment is located at a higher position than the uppermost part of the packaging body 40 in the first embodiment. Therefore, by deforming the packaging unit 1, the drawout 43 can be positioned at a higher position, thus improving the wire extraction performance without the need for structures such as arms.

[0103] Furthermore, in the second embodiment, which includes the first to third variations described above, unlike the first embodiment, the packaging body 40 includes: a movable body 51 having a drawout 43; and a telescopic member 52. Thus, by extending the telescopic member 52, the drawout 43 can be positioned at a higher position. Moreover, since the lifting unit 50 is enclosed within the packaging body 40, a separate drawout device from the packaging unit 1 is not required when drawing out the wire 10.

[0104] Furthermore, in the second embodiment, which includes the first to third variations described above, it is also as follows: Figure 4 As shown, it is preferable that the angle θ1 is greater than or equal to the angle θ2. Therefore, in the second embodiment, which includes the first to third variations described above, it is also preferable that the height Z of the extraction port 43 is more than 1.5 times the height Y of the holding portion 413, just as in the first embodiment.
