[0003] [Patent Document 1] Patent No. 6895671 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, for example, the cooling capacity that adults require from a neck cooler may be higher than the cooling capacity that children require from a neck cooler. As such, the cooling capacity required from a neck cooler varies from person to person.

[0009] Exemplary embodiments will now be described in detail with reference to the accompanying drawings.

[0010] FIG. 1 is a perspective view of a neck cooling device 100. The neck cooling device 100 is wrapped around the neck of a living body (e.g., a human) to cool the neck. The neck cooling device 100 comprises a first cooling device body 1 formed to surround a predetermined axis A and wrapped around the neck, a second cooling device body 3 formed to surround the predetermined axis A and overlapped on the first cooling device body 1 in the direction of axis A, and a connector 5 that detachably connects the first cooling device body 1 and the second cooling device body 3 to each other. In the following description, the direction of axis A will be referred to as the "axial direction," and the circumferential direction about axis A will be simply referred to as the "circumferential direction." In other words, the circumferential direction is the direction in which the neck cooling device 100 is wrapped around.

[0011] Fig. 2 is a plan view of the first cooling device body 1. Fig. 3 is a cross-sectional view of the first cooling device body 1 taken along line III-III in Fig. 1.

[0012] The first cooling device body 1 includes a cooling agent 11 that absorbs heat and changes from a solid phase to a liquid phase, and an exterior 12 that accommodates the cooling agent 11.

[0013] The ice pack 11 is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The ice pack 11 contains, for example, an aliphatic hydrocarbon. The aliphatic hydrocarbon is, for example, paraffin or a saturated aliphatic hydrocarbon. The ice pack 11 contains, for example, tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ) and octadecane (C 18 H 38) Ice pack 11 may contain only one or two of tetradecane, hexadecane, and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, ice pack 11 may further contain super absorbent polymer (SAP), water, aroma, graphite, organic matter, minerals, etc. The melting point of ice pack 11 is, for example, room temperature. The melting point of ice pack 11 is preferably 5°C or higher and 35°C or lower, and more preferably 15°C or higher and 35°C or lower. When ice pack 11 is in the solid phase or liquid phase, it absorbs the heat of the human body as sensible heat. When ice pack 11 changes from the solid phase to the liquid phase, it absorbs the heat of the human body as latent heat, more specifically, heat of fusion.

[0014] The exterior 12 has a curved arch portion 20 and a first free end portion 21 and a second free end portion 22 extending from both ends of the arch portion 20, respectively. The exterior 12 is formed hollow and contains the ice pack 11. Specifically, the exterior 12 is formed in a substantially cylindrical shape. That is, the exterior 12 has a substantially annular cross section. The interiors of the arch portion 20, the first free end portion 21, and the second free end portion 22 are in communication with each other.

[0015] The arch portion 20 extends along a curved axis X0, which extends in the shape of an arc with a predetermined curvature.

[0016] The first free end 21 includes a first linear portion 24 that extends linearly. Specifically, the first linear portion 24 extends along a linear axis X1. The second free end 22 includes a second linear portion 25 that extends linearly. Specifically, the second linear portion 25 extends along a linear axis X2. The axes X1 and X2 extend from both ends of the axis X0, respectively.

[0017] The exterior 12 has a rigidity sufficient to maintain a constant outer shape whether the ice pack 11 is in a solid or liquid phase. Specifically, the constant outer shape is a shape in which the first free end 21 and the second free end 22 are close to each other in the circumferential direction, as shown in FIGS. 2 and 3 . In other words, when no external force is applied to the first cooling device body 1, the first free end 21 and the second free end 22 are close to each other in the circumferential direction. Note that the first free end 21 and the second free end 22 may be in contact with each other when no external force is applied. Hereinafter, the state in which the first free end and the second free end are close to each other in the circumferential direction or the state in which the first free end and the second free end are in contact with each other will be referred to as the "natural state."

[0018] Because exterior packaging 12 contains ice pack 11, when ice pack 11 is in a solid phase, a constant outer shape is maintained by the rigidity of both ice pack 11 and exterior packaging 12. When ice pack 11 is in a liquid phase, the rigidity of ice pack 11 is low, so a constant outer shape is maintained mainly by the rigidity of exterior packaging 12. Thus, first free end 21 and second free end 22 are maintained in a state of being close to or in contact with each other in the circumferential direction by the rigidity of exterior packaging 12, regardless of whether ice pack 11 is in a solid or liquid phase.

[0019] However, the exterior 12 has elasticity. That is, the exterior 12 can elastically deform regardless of whether the ice pack 11 is in a solid or liquid phase. Specifically, the exterior 12 can elastically deform so that the first free end 21 and the second free end 22 move away from each other. A user can grasp the first free end 21 and the second free end 22 and pull them away from each other to form a gap between the first free end 21 and the second free end 22 large enough to insert the user's neck. The user can wear the first cooling device main body 1 around their neck by passing their neck between the first free end 21 and the second free end 22. When the external force separating the first free end 21 and the second free end 22 is removed (i.e., when the user releases their hands from the first free end 21 and the second free end 22), the rigidity of the exterior 12 allows the exterior 12 to return to its natural state, i.e., a state in which the first free end 21 and the second free end 22 are close to or in contact with each other in the circumferential direction.

[0020] For example, the exterior 12 is formed of one or a mixture of resins such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).

[0021] For example, the exterior 12 may be formed by laminating thermoplastic polyurethane, nylon, polyvinyl chloride, polyethylene, and polyurethane. More specifically, the exterior 12 may be formed by laminating nylon and polyvinyl chloride in order on the outside of the thermoplastic polyurethane, and polyethylene and polypropylene in order on the inside of the thermoplastic polyurethane.

[0022] 4 is a plan view of the second cooling device body 3. In this example, the configuration of the second cooling device body 3 is the same as that of the first cooling device body 1. That is, the second cooling device body 3 comprises an ice pack 31 and an exterior 32 that houses the ice pack 31. The ice pack 31 is the same as the ice pack 11 of the first cooling device body 1. In this example, the second cooling device body 3 is worn around the neck.

[0023] The exterior 32 has a curved arch portion 40 and a first free end portion 41 and a second free end portion 42 extending from both ends of the arch portion 40. The arch portion 40 extends along a curved axis X3. The axis X3 extends in an arc shape with a predetermined curvature.

[0024] The first free end 41 includes a first linear portion 44 that extends linearly. Specifically, the first linear portion 44 extends along a linear axis X4. The second free end 42 includes a second linear portion 45 that extends linearly. Specifically, the second linear portion 45 extends along a linear axis X5. The axes X4 and X5 extend from both ends of the axis X3, respectively.

[0025] The exterior casing 32 has enough rigidity to maintain a constant outer shape whether the ice pack 31 is in a solid or liquid phase, and is also capable of elastic deformation so that the first free end 41 and the second free end 42 move away from each other. The constant outer shape is a shape in which the first free end 41 and the second free end 42 are close to each other in the circumferential direction, as shown in Fig. 4. In other words, when no external force is acting on the second cooling device body 3, the first free end 41 and the second free end 42 are in their natural state.

[0026] 1, the connector 5 is disposed between the first cooling device body 1 and the second cooling device body 3. Specifically, the connector 5 is disposed between the opposing surface of the first cooling device body 1 facing the second cooling device body 3 and the opposing surface of the second cooling device body 3 facing the first cooling device body 1.

[0027] A plurality of connectors 5 are arranged in the circumferential direction. In this example, four connectors 5 are arranged in the circumferential direction. Specifically, two connectors 5 are arranged on the arch portions 20, 40, one connector 5 is arranged on the first free end portions 21, 41, and one connector 5 is arranged on the second free end portions 22, 42.

[0028] The connector 5 includes a first connector 51 and a second connector 52. The first connector 51 is provided on the first cooling device body 1. The second connector 52 is provided on the second cooling device body 3. The second connector 52 is detachably connected to the first connector 51. In this example, the first connector 51 and the second connector 52 are snap buttons.

[0029] As shown in Fig. 2, the first connecting portion 51 includes a convex part 61 and a concave part 71. In this example, when the first cooling device body 1 is cut along a plane that passes between the first free end portion 21 and the second free end portion 22 and includes the axis A, the convex part 61 is arranged on one side (in this example, the part of the first cooling device body 1 on the left side of the paper in Fig. 2), and the concave part 71 is arranged on the other side (in this example, the part of the first cooling device body 1 on the right side of the paper in Fig. 2).

[0030] As shown in Fig. 4, the configuration of the second connecting portion 52 is the same as the configuration of the first connecting portion 51. That is, the second connecting portion 52 includes a convex part 61 and a concave part 71. When the second cooling device body 3 is cut along a plane that passes between the first free end portion 41 and the second free end portion 42 and includes the axis A, the convex part 61 is arranged on one side (in this example, the part of the second cooling device body 3 on the left side of the paper in Fig. 4), and the concave part 71 is arranged on the other side (in this example, the part of the second cooling device body 3 on the right side of the paper in Fig. 4).

[0031] The convex parts 61 of the first connecting part 51 detachably fit into the corresponding concave parts 71 of the second connecting part 52. The convex parts 61 of the second connecting part 52 detachably fit into the corresponding concave parts 71 of the first connecting part 51. In this way, the second connecting part 52 is detachably connected to the first connecting part 51.

[0032] The first connecting portion 51 is provided on the opposing surface of the exterior 12 of the first cooling device body 1 that faces the second cooling device body 3. The second connecting portion 52 is provided on the opposing surface of the exterior 32 of the second cooling device body 3 that faces the first cooling device body 1.

[0033] Specifically, as shown in FIG. 5, the convex part 61 of the first connecting part 51 has a base 62 and a convex body 65 including a protrusion 66. FIG. 5 is an exploded perspective view illustrating the attachment structure of the convex part 61 to the exterior casing 12. The convex body 65 is fitted into the base 62. The base 62 has a flexible plate 63 and a pole 64 into which the convex body 65 is fitted. In this example, the plate 63 is formed in a disk shape. The pole 64 extends in the thickness direction of the plate 63. One end of the pole 64 is fixed to approximately the center of the plate 63 in a plan view. Of both surfaces in the thickness direction of the plate 63, the surface opposite to the surface to which the pole 64 is fixed is in contact with the exterior casing 12 of the first cooling device main body 1. A cover sheet 67 is arranged between the convex body 65 and the plate 63. The pole 64 penetrates the cover sheet 67. The cover sheet 67 covers the plate 63. The cover sheet 67 is joined to the exterior 12 so as to press the plate 63 against the exterior 12. The joining is achieved by, for example, thermal welding. In this manner, the base 62 is fixed to the exterior 12. As described above, the convex body 65 is fitted into the base 62. In this manner, the convex part 61 is attached to the exterior 12.

[0034] Similarly, as shown in FIG. 6, the recessed component 71 has a base 72 and a recessed body 75 including a recess 76. FIG. 6 is an exploded perspective view illustrating the mounting structure of the recessed component 71 to the exterior casing 12. The recessed body 75 is fitted into the base 72. The protrusion 66 of the protruding body 65 is inserted into the recess 76 of the recessed body 75. The base 72 has a flexible plate 73 and a pole 74 into which the recessed body 75 is fitted. In this example, the plate 73 is formed in a disk shape. The pole 74 extends in the thickness direction of the plate 73. One end of the pole 74 is fixed to approximately the center of the plate 73 in a plan view. Of both surfaces in the thickness direction of the plate 73, the surface opposite to the surface to which the pole 74 is fixed is in contact with the exterior 12 of the first cooling device main body 1. A cover sheet 77 is arranged between the recessed body 75 and the plate 73. The pole 74 penetrates the cover sheet 77. The cover sheet 77 covers the plate 73. The cover sheet 77 is joined to the exterior casing 12 so as to press the plate 73 against the exterior casing 12. The joining is achieved by, for example, thermal welding. In this manner, the base 72 is fixed to the exterior casing 12. As described above, the concave body 75 is fitted into the base 72. In this manner, the concave part 71 is attached to the exterior casing 12.

[0035] The above has explained the mounting structure of the convex part 61 and the concave part 71 of the first connecting part 51 to the exterior 12 of the first cooling device main body 1, but the same applies to the mounting structure of the convex part 61 and the concave part 71 of the second connecting part 52 to the exterior 32 of the second cooling device main body 3.

[0036] Next, we will explain how to assemble the neck cooling device 100. Figure 7 is an explanatory diagram for explaining how to assemble the neck cooling device 100.

[0037] First, the second cooling device body 3 is placed on the first cooling device body 1 so that the first connecting portion 51 of the first cooling device body 1 and the second connecting portion 52 of the second cooling device body 3 face each other in the axial direction. Next, the convex parts 61 of the first connecting portion 51 are fitted into the corresponding concave parts 71 of the second connecting portion 52. The convex parts 61 of the second connecting portion 52 are fitted into the corresponding concave parts 71 of the first connecting portion 51. In this way, the neck cooling device 100 as shown in FIG. 1 is assembled.

[0038] Next, we will explain how to use the neck cooling device 100. Figure 8 is an explanatory diagram for explaining the state in which the user is wearing the neck cooling device 100.

[0039] The ice packs 11, 31 are in a solid phase at room temperature. At this time, the neck cooler 100 is in a natural state in which the first free end portions 21, 41 and the second free end portions 22, 42 are close to or in contact with each other in the circumferential direction.

[0040] The user grasps the first free end portions 21, 41 and the second free end portions 22, 42 and moves the first free end portions 21, 41 and the second free end portions 22, 42 away from each other. The user passes their neck through the gap between the first free end portions 21, 41 and the second free end portions 22, 42 and wraps the neck cooling device 100 around their neck. Finally, the user releases their hands from the first free end portions 21, 41 and the second free end portions 22, 42. As a result, as shown in FIG. 8 , the neck cooling device 100 returns to its natural state in which the first free end portions 21, 41 and the second free end portions 22, 42 are close to or in contact with each other in the circumferential direction. Because the neck cooling device 100 is formed into a closed ring shape as a whole, it is securely attached to the neck and is prevented from coming off the neck.

[0041] When neck cooling device 100 is wrapped around the neck, ice packs 11, 31 absorb heat from the neck. As a result, ice packs 11, 31 melt and change into a liquid phase. Ice packs 11, 31 absorb heat using not only sensible heat but also latent heat, so they can efficiently absorb heat from the neck.

[0042] Fig. 9 is an explanatory diagram illustrating a state in which a user is wearing a neck cooling device 100 with its cooling capacity changed. For example, if the user is a child, or if the user is wearing the neck cooling device 100 on a day that is not extremely hot, the user may want to reduce the cooling capacity of the neck cooling device 100. In this case, the user wears only the first cooling device main body 1 around their neck, as shown in Fig. 9. This reduces the contact area of ​​the neck cooling device 100 with the user's neck, and the cooling capacity of the neck cooling device 100 can be reduced.

[0043] This neck cooling device 100 is equipped with a connector 5 that detachably connects the first cooling device main body 1 and the second cooling device main body 3 to each other. Therefore, the neck cooling device 100 can be switched between a state in which the first cooling device main body 1 and the second cooling device main body 3 are connected (hereinafter referred to as the "first state") and a state in which only the first cooling device main body 1 is present (hereinafter referred to as the "second state"). The neck cooling device 100 in the first state has a higher cooling capacity than the neck cooling device 100 in the second state. Specifically, the neck cooling device 100 in the first state can increase the contact area with the user's neck compared to the neck cooling device 100 in the second state, thereby enhancing the cooling effect on the user. Furthermore, the neck cooling device 100 in the first state contains a larger amount of ice packs 11, 31 in the exterior packaging 12, 32 than the neck cooling device 100 in the second state, thereby extending the cooling time. In this way, the neck cooling device 100 can change the cooling capacity between the first state and the second state.

[0044] The connector 5 is disposed between the first cooling device main body 1 and the second cooling device main body 3, and therefore the connector 5 is unlikely to be exposed to the outside. As a result, when using the neck cooling device 100, hair is unlikely to become tangled in the connector 5.

[0045] The connector 5 includes a first connecting portion 51 provided on the first cooling device body 1 and a second connecting portion 52 provided on the second cooling device body 3, so that the connector 5 can be held integrally with the first cooling device body 1 and the second cooling device body 3. As a result, when the first cooling device body 1 and the second cooling device body 3 are separated from each other, the connector 5 does not separate from the first cooling device body 1 and the second cooling device body 3, making management easier.

[0046] Since a plurality of connectors 5 are arranged in the circumferential direction of the neck cooling device 100, the second cooling device body 3 is prevented from shifting relative to the first cooling device body 1 while the neck cooling device 100 is in use.

[0047] Since the first connecting part 51 and the second connecting part 52 are snap buttons, when using the neck cooling device 100, hair is less likely to become tangled in the first connecting part 51 and the second connecting part 52 than if the first connecting part 51 and the second connecting part 52 were, for example, hook-and-loop fasteners.

[0048] <<Variation>> Fig. 10 is a perspective view of a neck cooling device 200 according to a modified example. Fig. 11 is a plan view of a first cooling device main body 1 according to a modified example. Fig. 12 is a plan view of a second cooling device main body 3 according to a modified example. The neck cooling device 200 differs from the neck cooling device 100 according to the embodiment in the configuration of the connector 205. The following will mainly explain the configuration of the neck cooling device 200 that differs from the neck cooling device 100 according to the embodiment. Note that in the neck cooling device 200, the same reference numerals as those in the neck cooling device 100 according to the embodiment have the same configuration as the neck cooling device 100 according to the embodiment, and therefore explanations thereof will be omitted.

[0049] In this example, thirteen connectors 205 are arranged in the circumferential direction. Each connector 205 includes a first connector 251 and a second connector 252. The first connector 251 and the second connector 252 are magnets. The magnets are, for example, ferrite magnets, neodymium magnets, etc. The first connector 251 and the second connector 252 are round, but may also be polygonal, and the shapes of the first connector 251 and the second connector 252 are not limited.

[0050] The first connecting part 251 is provided on the opposing surface of the first cooling device main body 1 that faces the second cooling device main body 3. Specifically, as shown in Fig. 13, the first connecting part 251 is covered with a cover sheet 267 and is sandwiched between the exterior 12 of the first cooling device main body 1 and the cover sheet 267. Fig. 13 is an exploded perspective view for explaining the attachment structure of the first connecting part 251 to the exterior 12. The cover sheet 267 is joined to the exterior 12. The joining is achieved by, for example, thermal welding.

[0051] The second connecting portion 252 is provided on the opposing surface of the second cooling device body 3 facing the first cooling device body 1. Specifically, like the first connecting portion 251, the second connecting portion 252 is covered with a cover sheet and is sandwiched between the exterior 32 of the second cooling device body 3 and the cover sheet. The cover sheet is bonded to the exterior 32. The bonding is achieved by, for example, heat welding.

[0052] 11, the magnetic poles of the first connecting portions 251 that are adjacent in the circumferential direction are different from each other. That is, when viewed from the axial direction, the first connecting portions 251 with north poles and the first connecting portions 251 with south poles are arranged alternately in the circumferential direction. The magnetic poles on the front and back of the first connecting portions 251 are different.

[0053] 12, the magnetic poles of adjacent second coupling portions 252 in the circumferential direction are different. That is, when viewed from the axial direction, second coupling portions 252 with north poles and second coupling portions 252 with south poles are arranged alternately in the circumferential direction. The front and back surfaces of the second coupling portions 252 have different magnetic poles.

[0054] In the first connecting portion 251 and the second connecting portion 252 that are connected to each other, the magnetic pole of the first connecting portion 251 and the magnetic pole of the second connecting portion 252 are different from each other. That is, the first connecting portion 251 with an N pole corresponds to the second connecting portion 252 with an S pole, and the first connecting portion 251 with an S pole corresponds to the second connecting portion 252 with an N pole. With this configuration, when the second cooling device body 3 is overlapped on the first cooling device body 1 in the axial direction so that the first connecting portion 251 and the second connecting portion 252 face each other in the axial direction, the second cooling device body 3 is detachably connected to the first cooling device body 1 by the magnetic force of the first connecting portion 251 and the second connecting portion 252.

[0055] According to neck cooling device 200, first connecting portion 251 and second connecting portion 252 are magnets, so first connecting portion 251 and second connecting portion 252 are attracted to each other by magnetic force, facilitating attachment and detachment of first cooling device body 1 and second cooling device body 3. Specifically, first cooling device body 1 and second cooling device body 3 can be connected without pressing first cooling device body 1 and second cooling device body 3 in opposing directions. More specifically, because first connecting portion 251 and second connecting portion 252 are magnets, first cooling device body 1 and second cooling device body 3 can be connected by simply bringing second cooling device body 3 close to first cooling device body 1, without pressing second cooling device body 3 toward first cooling device body 1.

[0056] Furthermore, since the first connecting part 251 and the second connecting part 252 are magnets, when using the neck cooling device 200, hair is less likely to become tangled in the first connecting part 251 and the second connecting part 252 than if the first connecting part 251 and the second connecting part 252 were hook-and-loop fasteners.

[0057] In addition, because the first connecting portion 251 and the second connecting portion 252 are magnets, when the neck cooling device 200 is used, the magnetic field of the magnets promotes blood flow in the neck. Specifically, the magnetic field of the magnets acts on the cells, nervous system, blood flow system, etc. of the neck, thereby regulating the biomagnetic field and bioelectric current. In particular, in this example, the magnetic poles of the first connecting portions 251 adjacent in the circumferential direction are different from each other, and the magnetic poles of the second connecting portions 252 adjacent in the circumferential direction are different from each other. This allows the magnetic force to spread over a wide area, further promoting blood flow in the neck. For example, the strength of one magnet is 2000 gauss, which further promotes blood flow in the neck.

[0059] The living body to be cooled by the neck cooling device 100 is not limited to a human being, but may also be an animal such as a dog or a cat.

[0060] The neck cooling device 100 has two stages of cooling device bodies (that is, a first cooling device body 1 and a second cooling device body 3), but the number of stages of the cooling device bodies is not limited, and may be three or more stages.

[0061] For example, the outer shape of the exterior 12 of the first cooling device body 1 is not limited to the shape described above. The arch portion 20 may be curved as a whole and may include a straight portion. The first free end 21 may be curved without including the first straight portion 24. The second free end 22 may be curved without including the second straight portion 25. The same applies to the outer shape of the exterior 32 of the second cooling device body 3. The outer shape of the exterior 12 of the first cooling device body 1 may be different from the outer shape of the exterior 32 of the second cooling device body 3. For example, the outer shape of the exterior 32 of the second cooling device body 3 may be formed only by the arch portion 40, without having the first free end 41 and the second free end 42. In this case, the second cooling device body 3 does not need to be wrapped around the neck.

[0062] The ice pack 31 of the second cooling device body 3 may be different from the ice pack 11 of the first cooling device body 1. For example, the material of the ice pack 31 may be different from the material of the ice pack 11, and the melting point of the ice pack 31 may be different from the melting point of the ice pack 11.

[0063] The connector 5 may be an integrated member without including the first connector 51 and the second connector 52. For example, the connector 5 may be a band that binds the first cooling device body 1 and the second cooling device body 3 together, and the connector 5 may be separated from the first cooling device body 1 and the second cooling device body 3 when the first cooling device body 1 and the second cooling device body 3 are separated from each other.

[0064] The connector 5 may be disposed on a surface other than the opposing surfaces of the first cooling device body 1 and the second cooling device body 3. For example, if the connector 5 is a band, the connector 5 may be wrapped around the outer circumferential surface other than the opposing surfaces of the first cooling device body 1 and the second cooling device body 3 to connect the first cooling device body 1 and the second cooling device body 3.

[0065] There are no limitations on the number and arrangement of the connectors 5. Only one connector 5 may be arranged in the circumferential direction.

[0066] The configurations of the first connecting portion 51 and the second connecting portion 52 are not limited to the configurations described above. For example, the first connecting portion 51 may have only the convex part 61. In this case, the second connecting portion 52 may have only the concave part 71. For example, the first connecting portion 51 may have only the concave part 71. In this case, the second connecting portion 52 may have only the convex part 61.

[0067] The first connecting portion 51 and the second connecting portion 52 may be hook-and-loop fasteners.

[0068] In the cooling device 200 according to the modified example, the first connecting portions 251 adjacent to each other in the circumferential direction may have the same magnetic pole, and the second connecting portions 252 adjacent to each other in the circumferential direction may have the same magnetic pole.

[0069] [Aspect] The above embodiments are specific examples of the following aspects.

[0070] (Aspect 1) The neck cooling device 100, 200 is a neck cooling device 100, 200 that is wrapped around the neck of a living body, and comprises a first cooling device body 1 that is formed to surround a predetermined axis A and is wrapped around the neck, a second cooling device body 3 that is formed to surround the axis A and is stacked on the first cooling device body 1 in the direction of the axis A, and a connecting device 5, 205 that detachably connects the first cooling device body 1 and the second cooling device body 3 to each other.

[0071] According to this configuration, the connector 5, 205 can be used to alternate between a state in which the first cooling device main body 1 and the second cooling device main body 3 are connected and a state in which only the first cooling device main body 1 is present. The neck cooling device 100, 200 in a state in which the first cooling device main body 1 and the second cooling device main body 3 are connected has a higher cooling capacity than the neck cooling device 100, 200 in a state in which only the first cooling device main body 1 is present. In this way, the cooling capacity of the neck cooling devices 100, 200 can be changed.

[0072] (Aspect 2) In the neck cooling devices 100 and 200 according to the first aspect, the second cooling device body 3 is wrapped around the neck.

[0073] According to this configuration, the contact area of ​​the second cooling device body 3 with the neck is increased compared to when the second cooling device body 3 is not wrapped around the neck, thereby enhancing the cooling effect on the neck.

[0074] (Aspect 3) In the neck cooling device 100, 200 according to the first or second aspect, the connector 5, 205 is disposed between the first cooling device body 1 and the second cooling device body 3.

[0075] According to this configuration, the connector 5, 205 is unlikely to be exposed to the outside, so that hair is unlikely to become entangled in the connector 5, 205 when the neck cooling device 100, 200 is used.

[0076] (Aspect 4) In the neck cooling device 100, 200 described in any one of aspects 1 to 3, the connecting device 5, 205 includes a first connecting portion 51, 251 provided on the first cooling device main body 1 and a second connecting portion 52, 252 provided on the second cooling device main body 3 and detachably connected to the first connecting portion 51, 251.

[0077] According to this configuration, the connectors 5, 205 can be held integrally with the first cooling device body 1 and the second cooling device body 3. As a result, when the first cooling device body 1 and the second cooling device body 3 are separated from each other, the connectors 5, 205 do not separate from the first cooling device body 1 and the second cooling device body 3, making management easier.

[0078] (Aspect 5) In the neck cooling device 100, 200 according to any one of the first to fourth aspects, a plurality of the connectors 5, 205 are arranged in the winding direction of the neck cooling device 100, 200.

[0079] According to this configuration, the second cooling device main body 3 is prevented from shifting relative to the first cooling device main body 1 while the neck cooling devices 100, 200 are in use. [Explanation of symbols]
