[0008] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and duplicated description will be omitted. The embodiment described below shows a representative embodiment of the present invention, and the scope of the present invention is not narrowly interpreted by this. Even if it is described in this specification that each of the cord container and the cord container set according to the present invention has multiple effects, each of the cord container and the cord container set according to the present invention only needs to have at least one effect. The effects described in this specification are merely examples and are not limited, and other effects may also be provided.

[0009] The explanation will be given in the following order: 1. Introduction 2. Cord container according to the first embodiment of the present invention, and cord container set including the cord container and cover 3. Cord storage device according to the second embodiment of the present invention, and cord storage device set including said cord storage device and cover device 4. Modifications of the present invention

[0010] 1. Introduction For example, if cords (wires) connected to devices such as computers, monitors, printers, and smartphones are carelessly routed across a desk, they can become messy and ruin the aesthetic appearance. Although there are hard cases available for housing and holding such cords, these cases are themselves bulky and therefore inconvenient to carry in a pocket or bag.Furthermore, such hard cases require a structure for opening and closing the case and a structure for winding the cord around it, making it cumbersome to take the cord in and out.

[0011] In view of these problems, the inventors have developed a cord container according to each embodiment of the present invention, and a cord container set including the cord container and a cover.

[0012] <2. Cord holder according to the first embodiment of the present invention, and cord holder set including the cord holder and cover> (Configuration of cord storage device) Hereinafter, the configuration of a cord receiving device according to a first embodiment of the present invention will be described with reference to the drawings. Fig. 1A is a plan view of a cord receiving device 10 according to a first embodiment of the present invention, and Fig. 1B is a side view of the cord receiving device 10 according to the first embodiment of the present invention.

[0013] The cord storage device 10 is intended to store and hold, for example, cords (cables) used for electrical connection between devices, cords for earphones, headphones, and the like. In the following, a description will be given of a cord C as an example of an object to be housed and held by the cord housing 10. Examples of the cord C include a USB cord, an HDMI (registered trademark) cord, a power cord, and a VGA cord.

[0014] As an example, the cord container 10 is formed from a flexible sheet. That is, the cord container 10 is formed from an elastically deformable sheet (preferably a sheet that has both flexibility and strength). Examples of materials for the sheet include plastic, vinyl, silicone rubber, synthetic rubber, and synthetic paper. As an example, the cord storage device 10 is made of a transparent or semi-transparent material. Note that it is preferable that at least a portion of the cord storage device 10 is transparent or semi-transparent, but the cord storage device 10 may be entirely opaque.

[0015] The cord receiving device 10 has a structure suitable for receiving and holding the cord C in a wound state, which may have a thickness that is less than 20% of the width, for example.

[0016] The cord housing device 10 is formed with a cord housing section CS having an open space capable of holding the wound cord C while maintaining the wound state when the wound cord C is introduced. The open space is an internal space having openings such as a cord entrance / exit A, openings A1, A2, etc., which will be described later.

[0017] As an example, the cord storage device 10 has a rectangular (including square) shape in plan view with the four corners cut out (hereinafter, these cut-out portions will be referred to as "cut-out portions") (see FIG. 1).

[0018] The cord housing section CS is constituted by a base section 50 and first and second pressing structures 100, 200 connected to the base section 50, as shown in FIG. 1A and FIG. 1B as an example.

[0019] The base portion 50 functions as a placement portion on which the wound cord C is placed. As an example, the base portion 50 has a shape that curves upward toward the four corners (four notched portions) in a side view. The base portion 50 may be, for example, in the shape of a flat plate. The cord C is placed on the base portion 50 with at least a portion of it wound thereon (see FIGS. 1 and 4).

[0020] The first pressing structure 100 is a lid-like part provided so as to cover a part of the open space of the cord housing part CS. The first pressing structure 100 can press a part C1 of the cord C placed on the base part 50 (a part of the cord C on the first pressing structure 100 side) against the base part 50. As an example, the first pressing structure 100 is connected to one outer edge part 50a of the base part 50 (see FIG. 1B).

[0021] The second pressing structure 200 is a lid-like part provided to cover the other part of the open space of the cord housing part CS. The second pressing structure 200 can press the other part C2 of the cord C placed on the base part 50 (the part of the cord C on the second pressing structure 200 side) against the base part 50. As an example, the second pressing structure 200 is connected to the other outer edge part 50b of the base part 50 (see FIG. 1B). Here, the other outer edge part 50b faces one outer edge part 50a.

[0022] As an example, the first and second pressing structures 100, 200 face each other. Hereinafter, the direction in which the first and second pressing structures 100, 200 face each other is referred to as the "first direction." The direction that is approximately parallel to the base portion 50 and perpendicular to the first direction is referred to as the "second direction."

[0023] When the first pressing structure 100 presses a part C1 of the cord C against the base part 50 and / or the second pressing structure 200 presses another part C2 of the cord C against the base part 50, the wound cord C is clamped in its thickness direction (a direction perpendicular to both the first and second directions) by at least one of the first and second pressing structures 100, 200 and the base part 50.

[0024] The first and second pressing structures 100, 200 are opposed to each other so as to form a cord entrance A which is an opening for inserting and removing the cord into and from the cord receiving device 10, for example.

[0025] The first and second pressing structures 100, 200, for example, face each other so that the cord C can be pressed against each other.

[0026] In a state in which the first and second pressing structures 100, 200 press the cord C against each other, the cord C, at least a portion of which is wound, is clamped in its width direction (first direction) by the first and second pressing structures 100, 200. This makes it possible to hold the cord C placed on the base portion 50 while maintaining the wound state.

[0027] The first pressing structure 100 includes, for example, a first inclined curved surface portion 100a and a first protruding portion 100b.

[0028] As an example, the first inclined curved surface portion 100a is a curved surface portion that has one end connected to one outer edge portion 50a of the base portion 50 and is inclined with respect to the base portion 50 so as to move away from the base portion 50 as it approaches the second pressing structure portion 200. As an example, the first inclined curved surface portion 100a is curved so as to be convex outward. As an example, the first inclined curved surface portion 100a is connected to one outer edge portion 50a of the base portion 50 at multiple points (for example, two points) so as to form an opening A1 (see FIGS. 3A to 3C).

[0029] 5, one end 100a1 in the second direction of the first inclined curved surface portion 100a is joined to one end 50a1 in the second direction of one outer edge portion 50a of the base portion 50, and the other end 100a2 in the second direction of the other end 50a2 in the second direction of one outer edge portion 50a of the base portion 50. Each joining is performed by, for example, heat fusion, adhesive, double-sided tape, or the like.

[0030] Returning to Fig. 1, the first inclined curved surface portion 100a can contact a portion C1 of the cord C placed on the base portion 50 from the side opposite to the base portion 50. When the first inclined curved surface portion 100a is in contact with the portion C1 of the cord C placed on the base portion 50, the first inclined curved surface portion 100a is elastically deformed in a direction away from the base portion 50, and a pressing force is applied from the first inclined curved surface portion 100a to the portion C1 of the cord C pressing it toward the base portion 50.

[0031] As an example, the first protruding portion 100b protrudes from the other end of the first inclined curved surface portion 100a along the base portion 50 toward the second pressing structure portion 200.

[0032] The second pressing structure 200 includes, for example, a second inclined curved surface portion 200a and a second protruding portion 200b.

[0033] As an example, the second inclined curved surface portion 200a is a curved surface portion that has one end connected to the other outer edge portion 50b of the base portion 50 and is inclined with respect to the base portion 50 so as to move away from the base portion 50 as it approaches the second pressing structure portion 200. As an example, the second inclined curved surface portion 200a is curved so as to be convex outward. As an example, the second inclined curved surface portion 200a is connected to the other outer edge portion 50b of the base portion 50 at multiple points (for example, two points) so as to form an opening A2 (see FIGS. 3A to 3C).

[0034] 5, one end 200a1 in the second direction of the second inclined curved surface portion 200a is joined to one end 50b1 in the second direction of the other outer edge portion 50b of the base portion 50, and the other end 200a2 in the second direction of the second inclined curved surface portion 200a is joined to the other end 50b2 in the second direction of the other outer edge portion 50b of the base portion 50. Each joining is performed by, for example, heat fusion, adhesive, double-sided tape, or the like.

[0035] 1, the second inclined curved surface portion 200a can contact the other part C2 of the cord C placed on the base part 50 from the side opposite to the base part 50. When the first inclined curved surface portion 100a is in contact with the other part C2 of the cord C placed on the base part 50, the second inclined curved surface portion 200a is elastically deformed in a direction away from the base part 50, and a pressing force is applied from the second inclined curved surface portion 200a to the other part C2 of the cord C pressing it toward the base part 50.

[0036] As an example, the second overhanging portion 200b overhangs from the other end of the second inclined curved surface portion 200a toward the first pressing structure portion 100 along the base portion 50. The second overhanging portion 200b faces the first overhanging portion 100b. The first and second overhanging portions 2100b, 200b also function as fall-off prevention portions that prevent the cord C held in the cord container 10 from falling off.

[0037] A cord entrance A is defined by the first and second inclined curved surface portions 100a, 100b and the first and second protruding portions 100b, 200b.

[0038] The cord receiving device 10 has a configuration in which the open space is narrowed and the cord receiving device 10 can be deformed into a flat state when the cord C is not received therein. In detail, the cord accommodation device 10 has flexibility, and the joint between the first pressing structure 100a and the base portion 50 and the joint between the second pressing structure 200a and the base portion 50 function like hinges, so that the cord accommodation device 10 can be easily crushed in the height direction (the direction perpendicular to both the first and second directions, the same applies below) without accommodating the cord C, as shown in FIG. 2A (perspective view) and FIG. 2B (plan view). The cord accommodation device 10 becomes flat (e.g., substantially flat) when crushed in the height direction. This allows the cord accommodation device 10 to be carried in a small space while maintaining the flat state, for example. Furthermore, when distributing the cord accommodation device 10, a large number of cord accommodation devices 10 can be packaged in a crushed state by stacking them, thereby saving space. In this specification, the term "flat state" includes not only a flat state, but also a state in which the opening space is narrowed and the cord accommodation device is partially crushed before becoming flat.

[0039] The cord accommodating device 10 is configured such that when an external force is applied from the outside of the cord accommodating device 10 toward the center of the cord accommodating section CS, the first and second pressing structures 100, 200 acting as lids rise up and the cord accommodating section CS opens more widely, making it easier to insert and remove the cord C. More specifically, since cord accommodation device 10 is flexible and has openings A1, A2, it is possible to easily and greatly expand cord entrance A in the first direction (easily and greatly contract in the second direction) by applying an external force to cord accommodation device 10 to cause elastic deformation, as shown in Fig. 3A (perspective view), Fig. 3B (side view), and Fig. 3C (plan view). Furthermore, at this time, since cord accommodation device 10 has base portion 50 that is curved upward toward the four corners in side view, base portion 50 and first and second pressing structure portions 100a, 200a can be easily elastically deformed by pressing base portion 50 from both outsides. As described above, the cord storage device 10 can open the cord entrance A wider by applying an external force, so that the cord C can be easily placed on the base portion 50. Thereafter, by releasing the external force, the cord storage device 10 elastically returns to its original shape, so that the cable C can be easily held in the cord storage device 10.

[0040] The cord housing CS has a structure that allows both ends of the cord C housed in the open space to be pulled out to the outside. More specifically, when the cord C is stored and held in the cord receiving device 10 when not in use, the cord C is stored and held within the cord receiving device 10 in a fully wound state, as shown in FIG. When cord C is stored and held in cord storage device 10 during use (when it is used to connect devices), for example, as shown in FIG. 4, the middle portion of cord C not including the connector portions at both ends is wound and held within cord storage device 10, and the portions of cord C including the connector portions at one and the other ends are pulled out to the outside via one and the other ends in the second direction of cord entrance / exit A.

[0041] (Cord storage set) As shown in Figures 6A and 6B, the cord storage device set 1 at least comprises a cord storage device 10 and a cover device formed separately from the cord storage device 10 and integrated with the cord storage device to cover and enclose at least the cord storage section CS. More specifically, the cord receiving device set 1 can be made up of a plurality of cord receiving devices 10, for example. The cord storage set 1 has one (inner) cord storage device 10 that stores a cord C, and another (outer) cord storage device 10 that serves as a cover for storing the first cord storage device 10. The other cord receiving device 10 is formed to be one size larger than the first cord receiving device 10, and is capable of holding and releasing the first cord receiving device 10 holding the cord C. When one cord storage device 10 holding a cord C is to be stored and held in another cord storage device 10, this can be done by bending the other cord storage device 10 (by deforming the cord entrance / exit A) in the same manner as when storing and holding the cord C in the first cord storage device 10 described above. At this time, the other cord accommodation device 10 can hold one of the cord accommodation devices 10 with the base portion 50 facing the opposite side to the base portion 50 of the first cord accommodation device 10. This makes it possible to prevent the cord entrances A of the first and other cord accommodation devices 10 from overlapping, thereby reducing exposure of the cord C.

[0042] When the cord C is held in the cord storage device set 1 when not in use, the cord C is stored and held in a fully wound state in one cord storage device 10, and the one cord storage device 10 is stored and held in another cord storage device 10, as shown in FIG. 6A, for example. When cord C is stored and held in cord storage device 10 during use (when used to connect devices), for example, as shown in FIG. 7, the middle portion of cord C not including the connector portions at both ends is wound and held within one cord storage device 10, and the one cord storage device 10 is stored and held within another cord storage device 10, and the portions including the connector portions at both ends of cord C are pulled out to the outside through the cord entrance A of the one cord storage device 10 and the cord entrance A of the other cord storage device 10 (see FIG. 6B).

[0043] In this embodiment, the cover that holds and houses one cord storage device 10 is Although another cord receiving device 10 having the same configuration as the first cord receiving device 10 is used, a cord receiving device having a different configuration from the first cord receiving device 10 may be used.

[0044] (An example of a manufacturing method for a cord storage device) 8A to 9C, a brief description will be given of an example of a method for manufacturing the cord receiving device 10. The cord receiving device 10 is formed from one synthetic resin sheet P, as an example. (Step 1) A development 1000-1 of the cord receiving device 10 is drawn (for example, printed) on a flexible synthetic resin sheet P (see FIG. 8A). (Step 2) The unfolded structure 1000-2 (the structure according to the unfolded view 1000-1) of the cord storage device 10 is cut out from the synthetic resin sheet P (see FIG. 8B). (Step 3) The deployment structure 1000-2 is folded in the directions of the arrows D1 and D2 in Fig. 8B, and the joint surfaces JF1 and JF2 are joined by, for example, heat fusion, adhesive, double-sided tape, etc., to generate the joint structure 1000-3 (see Fig. 9A). The part where the joint surfaces JF1 and JF2 are joined is the joint J. (Step 4) The cord receiving device 10 is cut out (see Figs. 9B and 9C). Specifically, the joint structure 1000-3 shown in Fig. 9A is separated into the outer gray part shown in Fig. 9B and the part 1000-4 that will become the cord receiving device 10 on the inside, to obtain the cord receiving device 10 (see Fig. 9C). At this time, part of the joint J remains in the cord receiving device 10.

[0045] (Effects of cord storage devices and cord storage device sets) The effects of the cord container 10 according to the first embodiment will be described below. The cord accommodation device 10 is configured such that, when a wound cord C is introduced, a cord accommodation section CS is formed having an opening space capable of holding the wound cord C while maintaining the wound state, and when the cord C is not accommodated, the opening space is narrowed and can be deformed into a flat state. In this case, in the cord accommodation device 10, the wound cord C can be easily inserted into and removed from the cord accommodation portion CS, and the cord C can be made flat when not accommodated. As a result, the cord container 10 can provide a cord container that does not require much effort to insert and remove the cord C and that is not bulky when the cord C is not housed therein.

[0046] On the other hand, with conventional cord housings (for example, the earphone case described in JP 2019-172369 A), in order to insert or remove the earphones, it is necessary to open and close the case body and the case lid, as well as wind / unwind the earphones around the cord winding column, making it time-consuming to insert or remove the earphones. Furthermore, the earphone case is a hard case and is bulky in itself, making it inconvenient to carry around.

[0047] Furthermore, the cord accommodation device 10 is a flexible cord accommodation device that includes a base portion 50 on which the cord C is placed, a first pressing structure 100 connected to the base portion 50 and capable of pressing a part C1 of the cord C placed on the base portion 50 against the base portion 50, and a second pressing structure 200 connected to the base portion 50 and capable of pressing another part C2 of the cord C placed on the base portion 50 against the base portion 50. In this case, the cord C can be inserted and removed by elastically deforming (flexing) the base portion 50 and the first and second pressing structures 100, 200, and after the cord C is accommodated, the elastic deformation is released (elastic return) to hold the cord C.

[0048] The first and second pressing structures 100, 200 face each other so as to be able to press the cord C against each other. This makes it possible to hold the cord C while maintaining the wound state.

[0049] The first and second pressing structures 100, 200 face each other so as to form a cord entrance A for inserting and removing the cord C into and from the cord container 10. In this case, the shape of the cord entrance A can be easily changed by elastically deforming the base 50 and the first and second pressing structures 100, 200, making it easy to insert and remove the cord C. Furthermore, in this case, it is also easy to insert and remove a portion of the cord C while holding the other portion of the cord C.

[0050] One outer edge 50a of the base part 50 and the first pressing structure 100 are connected at multiple points (for example, two points) to form an opening A1, and the other outer edge 50b of the base part 50 and the second pressing structure 200 are connected at multiple points (for example, two points) to form an opening A2. This makes it easier to deform the cord accommodation device 10, so that the cord C can be inserted and removed from the cord accommodation device 10 more easily.

[0051] The first pressing structure 100 has a first protruding portion 100b protruding toward the second pressing structure 200, and the second pressing structure 200 has a second protruding portion 200b protruding toward the first pressing structure 100. This makes it possible to more easily deform the cord entrance A by hooking a finger on at least one of the first and second protruding portions 100b, 200b.

[0052] According to the cord container 10, the cord C is surrounded and held by the base portion 50 and each of the first and second pressing structures 100, 200 (excluding the cord entrance A), so that the cord C can be protected.

[0053] The cord storage device 10 is convenient to carry since it is not bulky whether the cord C is stored or not, and when placed on a desk, it prevents the aesthetic appearance from being impaired both when not in use and when in use, and can also be used as a package when the cord C is sold as a product.

[0054] According to the cord receiving device 10, since it can be collapsed into a compact shape when not holding the cord C, it is convenient to carry and a large number of them can be distributed in a small space.

[0055] Since the cord storage device 10 is transparent or semi-transparent, the cord C can be seen from the outside. This allows the user to recognize that what is stored in the cord storage device 10 is a cord, and further, what type of cord this is.

[0056] The cord container 10 can also be used as a novelty item by printing a logo or other characters for advertising purposes on the outer surface of the base portion 50, for example.

[0057] The cord storage device 10, which stores the cord C in a wound state, is suitable for using the cord C in the stored state to connect devices to each other, for carrying the cord C in the stored state, and for distributing the cord C in the stored state (e.g., selling it in stores).

[0058] According to the cord storage device set 1 having the first and second cord storage devices 10, the first cord storage device 10 holding the cord C can be held by the second cord storage device 10 such that the base part 50 of the second cord storage device 10 covers the cord entrance / exit A of the first cord storage device 10. This provides excellent protection and packaging for the cord C, and makes it suitable for carrying around while holding the cord C and for distributing it as a product.

[0059] The cord storage set 1, which houses the cord C in a wound state, is suitable for using the cord C in the stored state to connect devices to each other, for carrying the cord C in the stored state, and for distributing the cord C in the stored state (e.g., selling it in stores).

[0060] In the cord container 10, the inclination angles of the first and second inclined curved surface portions 100a, 200a can be appropriately changed to accommodate cords C wound in various thicknesses.

[0061] When the cord receiving device 10 is formed from one synthetic resin sheet P, there is no need to make a plurality of molds, which allows for cost reduction.

[0062] Furthermore, in the case where the cord receiving device 10 is assembled three-dimensionally after the synthetic resin sheet P is cut into a predetermined shape, productivity can be improved.

[0063] <3. Cord holder according to the second embodiment of the present invention, and cord holder set including the cord holder and cover> (Configuration of cord storage device) The configuration of a cord receiving device 20 according to the second embodiment of the present invention will now be described with reference to the drawings.

[0064] Fig. 10A is a plan view of the cord receiving device 20. Fig. 10B is a side view of the cord receiving device 20. The cord receiving device 20 of the second embodiment has a similar configuration to the cord receiving device 10 of the first embodiment, except that the configurations of the first and second pressing structures 100, 200 are different.

[0065] As an example, cord accommodation device 20 has a structure suitable for accommodating and holding a wound cord C whose thickness can be 20% or more of its width. In other words, cord accommodation device 20 is intended to accommodate and hold a wound cord C that is thicker than the wound cord C that cord accommodation device 10 is intended to accommodate and hold.

[0066] In the cord accommodating device 20, the first pressing structure 100, as an example, has, as shown in Figures 10A and 10B, a plurality of (e.g., three) first upright portions 100c each having one end connected to one outer edge portion 50a of the base portion 50 and capable of being erected against the base portion 50, and a first extension portion including a first inclined curved surface portion 100a and a first protrusion portion 100b extending from the other ends of the plurality of first upright portions 100c toward the second pressing structure 200.

[0067] The multiple first standing portions 100c include, as an example, a first standing portion 100c connected to a middle portion in the second direction of one outer edge portion 50a of the base portion 50, a first standing portion 100c connected to one end portion in the second direction of one outer edge portion 50a, and a first standing portion 100c connected to the other end portion in the second direction of one outer edge portion 50a. Here, the width of the first standing portion 100c connected to the middle portion of one outer edge portion 50a is larger (for example, twice or more) than the width of the other first standing portions 100c.

[0068] In the cord accommodating device 20, the second pressing structure 200, as an example, has a plurality (e.g., three) of second upright portions 200c each having one end connected to the other outer edge portion 50b of the base portion 50 and capable of standing upright against the base portion 50, and a second extension portion including a second inclined curved surface portion 200a and a second protrusion portion 100b extending from the other end of the second upright portion 200c toward the first pressing structure 100.

[0069] The multiple second standing portions 200c include, for example, a second standing portion 200c connected to a middle portion in the second direction of the other outer edge portion 50b of the base portion 50, a second standing portion 200c connected to one end portion in the second direction of the other outer edge portion 50b, and a second standing portion 200c connected to the other end portion in the second direction of the other outer edge portion 50b. Here, the width of the second standing portion 200c connected to the middle portion of the other outer edge portion 50b is larger (for example, twice or more) than the width of the other second standing portions 200c.

[0070] In the cord accommodating device 20, one outer edge portion 50a of the base portion 50 is joined to multiple (e.g., three) first upright portions 100c so as to form multiple (e.g., two) openings A1, and the multiple (e.g., three) first upright portions 100c are joined to a first extension portion including a first inclined curved surface portion 100a and a first protrusion portion 100b.

[0071] In the cord accommodating device 20, the other outer edge portion 50b of the base portion 50 is joined to multiple (e.g., three) second upright portions 200c so as to form multiple (e.g., two) openings A2, and the multiple (e.g., three) second upright portions 200c are joined to a second extension portion including the second inclined curved surface portion 200a and the second protrusion portion 200b.

[0072] Each of the first standing portions 100c has a bent portion BP1 extending along the base portion 50. Each of the second standing portions 200c has a bent portion BP2 extending along the base portion 50. This allows the cord container 20 to be easily folded in the height direction to a flat state (for example, into a substantially flat plate shape), making it less bulky when carried and allowing a large number of units to be packaged compactly during distribution.

[0073] Like cord storage device 10, cord storage device 20 holds the middle part of the wiring portion of cord C, while allowing the parts of cord C including the connector portions at one and the other ends to be pulled out to the outside through cord entrance / exit A for use in connecting devices (see FIG. 11).

[0074] (Cord storage set) As shown in Figures 12A and 12B, the cord accommodation device set 2 at least comprises a cord accommodation device 20 and a cover device formed separately from the cord accommodation device 20 and integrated with the cord accommodation device to cover and enclose at least the cord accommodation portion. The cord receiving device set 2 can be composed of a plurality of cord receiving devices 20, for example. The cord receiving device set 2 has one (inner) cord receiving device 20 that holds a cord C, and another (outer) cord receiving device 20 that holds the first cord receiving device 20. The other cord receiving device 20 is formed to be one size larger than the first cord receiving device 20, and is capable of holding and releasing the first cord receiving device 20 holding the cord C. When one cord accommodating device 20 holding a cord C is to be accommodated and held in another cord accommodating device 20, this can be done by bending the other cord accommodating device 20 (by deforming the cord entrance / exit A) in the same manner as when accommodating and holding the cord C in the first cord accommodating device 20 described above. At this time, the other cord accommodation device 20 can hold one of the cord accommodation devices 20 with the base portion 50 facing the opposite side to the base portion 50 of the first cord accommodation device 20. This makes it possible to prevent the cord entrances A of the first and second cord accommodation devices 20 from overlapping, thereby reducing exposure of the cord C.

[0075] When the cord C is stored and held in the cord storage device set 2 when not in use, for example, as shown in FIG. 12A, the cord C is stored and held in a fully wound state in one cord storage device 20, and the one cord storage device 20 is stored and held in another cord storage device 10. When cord C is stored and held in cord accommodating device 20 during use (when used to connect devices), for example, as shown in Figure 13, the middle portion of cord C not including the connector portions at both ends is wound and stored and held in one cord accommodating device 20, and the one cord accommodating device 20 is stored and held in another cord accommodating device 20, and the portions including the connector portions at both ends of cord C are pulled out to the outside through the cord entrance A of the one cord accommodating device 20 and the cord entrance A of the other cord accommodating device 20 (see Figure 12B).

[0076] In this embodiment, the cover that holds and houses one cord receiving device 20 is Although another cord receiving device 20 having the same configuration as the first cord receiving device 20 is used, a cord receiving device having a different configuration from the first cord receiving device 20 may be used.

[0077] (An example of a manufacturing method for a cord storage device) 14A to 15C, a brief description will be given of an example of a method for manufacturing the cord receiving device 20. The cord receiving device 20 is formed from one synthetic resin sheet P, as an example. (Step 1) A development 2000-1 of the cord receiving device 20 is drawn (for example, printed) on a flexible synthetic resin sheet P (see FIG. 14A). (Step 2) The unfolded structure 2000-2 (the structure according to the unfolded view 2000-1) of the cord receiving device 20 is cut out from the synthetic resin sheet P (see FIG. 14B). (Step 3) The deployment structure 2000-2 is folded in the directions of the arrows D1 and D2 in FIG. 14B, and the joint surfaces JF1 and JF2 are joined by, for example, heat fusion, adhesive, double-sided tape, etc., to generate the joint structure 2000-3 (see 15A). The part where the joint surfaces JF1 and JF2 are joined is the joint J. (Step 4) The corners of each joint J are cut off to obtain the shape of the cord receiving device 20 (see Figs. 15B and 15C). Specifically, the corners of each joint J of the joint structure 2000-3 shown in Fig. 15A are colored gray, and the corners (gray parts) of the joint structure 2000-4 (see Fig. 15B) are cut off to obtain the cord receiving device 20 (see Fig. 15C). At this time, a part of the joint J (parts other than the corners) remains in the cord receiving device 20.

[0078] (Effects of cord storage devices and cord storage device sets) The cord accommodation device 20 of the second embodiment has the same effect as the cord accommodation device 10 of the first embodiment, and can accommodate a wound cord C that is thicker than the wound cord C that is the object of the cord accommodation device 10. The cord storage device set 2 having a plurality of cord storage devices 20 of the second embodiment has the same effect as the cord storage device set 1 having a plurality of cord storage devices 10 of the first embodiment, and can store a wound cord that is thicker than the wound cord that is to be stored by the cord storage device set 1.

[0079] In the cord receiver 20 of the second embodiment, the height dimensions of the first and second standing portions 100c, 200c can be appropriately changed to accommodate a wound cord of any thickness.

[0080] <4. Modifications of the present invention> The cord container of the present invention is not limited to the configurations described in the above embodiments, and can be modified as appropriate.

[0081] For example, a modified cord receiving device 30 shown in Figs. 16A and 16B has a case-like shape that opens on one side. More specifically, the cord accommodation device 30 includes a base portion 50 on which the cord is placed, a pressing structure 200c (second structure), and a connection portion 60 that connects the base portion 50 and the pressing structure 200c. The cord accommodation device 30 further includes a cover portion 70 that is connected to the base portion 50 and the connection portion 60. The cover portion 70 has a generally U-shaped cross section, and has bent portions BP on both sides (gusset portions) of the U. This allows the gusset portions to be crushed into a flattened state. A cord entrance A is formed in the cover portion 70 at a position opposite the connection portion 60. When an external force in the direction of the arrow P is applied to the cord container 30 with the pressing structure 200c in the closed state (cord entrance A is blocked) shown in FIG. 16A, the pressing structure 200c is opened and the cord entrance A is opened (see FIG. 16B), and when the external force is released, the pressing structure 200c is closed and the cord entrance A is blocked. An opening B is formed by the cover 70, the base 50, and the pressing structure 200c, and for example, the cord can be used to connect between devices by pulling out the parts including the connector parts at both ends of the cord through the opening B. Note that the connection side of the cover 70 with the base 50 and the base 50 may be rounded to fit the wound cord C. This allows the cord C to be held better.

[0082] The aforementioned openings A1 and A2 can function as holes into which the outermost cord can enter to prevent the wound cord C housed in the cord housing section from loosening, as shown in FIG. 17. More specifically, the cord C held in the cord accommodation device 10 in a wound state attempts to return to its original state by elastic restoration, and so there is a risk of the cord C falling out through the cord entrance A. However, with the cord accommodation device 10, as shown in Fig. 17, part of the cord C protrudes to the outside through the openings A1 and A2, allowing the elastic restoration force of the cord C to be released, and thus preventing the cord C from falling out through the cord entrance A.

[0083] As shown in FIG. 17, the openings A1 and A2 can also function as stoppers that prevent the wound cord C housed in the cord housing portion from rotating in the winding direction relative to the cord housing portion CS.

[0084] For example, in the cord container 20 of the second embodiment, the number of each of the first and second standing portions 100c, 200c may be two or less, or may be four or more. In any case, it is preferable that at least one opening A1 and one opening A2 are formed.

[0085] For example, in the cord receiver 20 of the second embodiment, each of the first and second standing portions 100c, 200c does not necessarily have to have a bent portion.

[0086] For example, in the cord receiver 20 of the second embodiment, at least one of the first and second protruding portions 100b, 200b may not be provided.

[0087] For example, in the cord receiver 20 of the second embodiment described above, each of the first and second pressing structures 100, 200 may have a flat surface portion substantially parallel to the base portion 50 instead of the inclined curved surface portion.

[0088] For example, in the cord receiving device of each of the above embodiments, the pressing structure, which is the lid-like portion, and the cord receiving portion may be made of different materials. [Explanation of symbols]
