Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, for example, the cooling capacity required by an adult for a neck cooler may be higher than that required by a child for a neck cooler. Thus, there are individual differences in the cooling capacity required for a neck cooler. Also, for example, the cooling capacity required for a neck cooler on a sweltering day may be higher than that required for a neck cooler on a day that is not a sweltering day. Thus, the cooling capacity required for a neck cooler can also vary depending on the climate.

[0005] The technology disclosed herein has been made in view of such points, and its object is to realize a neck cooler capable of changing the cooling capacity.

BEST MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, exemplary embodiments will be described in detail based on the drawings.

[0010] FIG. 1 is a perspective view of the neck cooler 100. The neck cooler 100 is wound around the neck of a living body (for example, a human) to cool the neck. The neck cooler 100 is formed so as to surround a predetermined axis A, and includes a first cooler body 1 wound around the neck, a second cooler body 3 formed so as to surround the predetermined axis A and overlapped with the first cooler body 1 in the direction of the axis A, and a connector 5 that detachably connects the first cooler body 1 and the second cooler body 3 to each other. In the following description, the direction of the axis A is referred to as the "axial direction", and the circumferential direction centered on the axis A is simply referred to as the "circumferential direction". The circumferential direction is, in other words, the winding direction of the neck cooler 100.

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

[0012] The first cooler body 1 includes a cold storage agent 11 that absorbs heat and changes from a solid phase to a liquid phase, and an exterior 12 that houses the cold storage agent 11.

[0013] The cold storage agent 11 is a PCM (Phase Change Material) that absorbs heat and changes from a solid phase to a liquid phase. The cold storage agent 11 contains, for example, aliphatic hydrocarbons. The aliphatic hydrocarbons are, for example, paraffin or aliphatic saturated hydrocarbons. The cold storage agent 11 is, as an aliphatic hydrocarbon, tetradecane (C 14 H 30 ), hexadecane (C 16 H 34 ), and octadecane (C 18 H 38It may contain at least one of them. The cold insulating agent 11 may contain only one or only two of tetradecane, hexadecane, and octadecane, or may contain all of them. In addition to aliphatic hydrocarbons, the cold insulating agent 11 may further contain a super absorbent polymer (SAP), water, aroma, graphite, organic substances, minerals, etc. The melting point of the cold insulating agent 11 is, for example, normal temperature. The melting point of the cold insulating agent 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 in the solid phase and the liquid phase, the cold insulating agent 11 absorbs the heat of the human body as sensible heat. When changing from the solid phase to the liquid phase, the cold insulating agent 11 absorbs the heat of the human body as latent heat, specifically, melting heat.

[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 in a hollow shape and houses the cold insulating agent 11. Specifically, the exterior 12 is formed in a substantially circular tube 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. The axis X0 extends in an arc shape with a predetermined curvature.

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

[0017] The outer casing 12 has sufficient rigidity to maintain a constant external shape regardless of whether the coolant 11 is in a solid or liquid phase. Specifically, the constant external shape is such that the first free end 21 and the second free end 22 are close to each other in the circumferential direction, as shown in Figures 2 and 3. In other words, when no external force is acting on the first cooler 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 when no external force is acting on them. 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, will be referred to as the "natural state".

[0018] Since the outer casing 12 houses the cooling agent 11, when the cooling agent 11 is in a solid phase, a constant external shape is maintained by the rigidity of both the cooling agent 11 and the outer casing 12. When the cooling agent 11 is in a liquid phase, the rigidity of the cooling agent 11 is small, so a constant external shape is maintained mainly by the rigidity of the outer casing 12. In this way, the first free end 21 and the second free end 22 are maintained in a state of close proximity or contact with each other in the circumferential direction by the rigidity of the outer casing 12, regardless of whether the cooling agent 11 is in a solid or liquid phase.

[0019] However, the outer casing 12 is elastic. That is, the outer casing 12 can be elastically deformed regardless of whether the coolant 11 is in a solid or liquid state. Specifically, the outer casing 12 can be elastically deformed so that the first free end 21 and the second free end 22 move away from each other. The user can grasp the first free end 21 and the second free end 22 and pull them apart to create a gap between them large enough to insert their neck. By passing their neck between the first free end 21 and the second free end 22, the user can attach the first cooling device body 1 to their neck. 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 outer casing 12 causes it to return to its natural state, i.e., 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 outer casing 12 is formed from one or more resins such as thermoplastic polyurethane (TPU), nylon, polyvinyl chloride (PVC), polyethylene (PE), and polypropylene (PP).

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

[0022] Figure 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 a cooling agent 31 and an outer casing 32 that houses the cooling agent 31. The cooling agent 31 is the same as the cooling agent 11 of the first cooling device body 1. In this example, the second cooling device body 3 is wrapped 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, respectively. The arch portion 40 extends along a curved axis X3. The axis X3 extends in the shape of a circular arc with a predetermined curvature.

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

[0025] The outer casing 32 has sufficient rigidity to maintain a constant external shape regardless of whether the coolant 31 is in a solid or liquid phase, and is elastically deformable so that the first free end 41 and the second free end 42 move away from each other. The constant external shape is such that the first free end 41 and the second free end 42 are close to each other in the circumferential direction, as shown in Figure 4. In other words, when no external force is acting on the second cooler body 3, the first free end 41 and the second free end 42 are in a natural state.

[0026] As shown in Figure 1, the connector 5 is positioned between the first cooler body 1 and the second cooler body 3. Specifically, the connector 5 is positioned between the opposing surface of the first cooler body 1 that faces the second cooler body 3 and the opposing surface of the second cooler body 3 that faces the first cooler body 1.

[0027] Multiple 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 sections 20 and 40, one connector 5 is arranged on the first free ends 21 and 41, and one connector 5 is arranged on the second free ends 22 and 42.

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

[0029] As shown in Figure 2, the first connecting portion 51 includes a convex part 61 and a concave part 71. In this example, when the first cooler body 1 is cut by a plane passing between the first free end 21 and the second free end 22 and containing axis A, the convex part 61 is located on one side (in this example, the left side of the first cooler body 1 in Figure 2), and the concave part 71 is located on the other side (in this example, the right side of the first cooler body 1 in Figure 2).

[0030] As shown in Figure 4, the configuration of the second connecting portion 52 is the same as that 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 cooler body 3 is cut by a plane that passes between the first free end 41 and the second free end 42 and includes axis A, the convex part 61 is located on one side (in this example, the left side of the second cooler body 3 in Figure 4), and the concave part 71 is located on the other side (in this example, the right side of the second cooler body 3 in Figure 4).

[0031] The protruding part 61 of the first connecting part 51 is detachably fitted into the corresponding recessed part 71 of the second connecting part 52. The protruding part 61 of the second connecting part 52 is detachably fitted into the corresponding recessed part 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 surface of the outer casing 12 of the first cooler body 1 that faces the second cooler body 3. The second connecting portion 52 is provided on the surface of the outer casing 32 of the second cooler body 3 that faces the first cooler body 1.

[0033] Specifically, as shown in Figure 5, the convex part 61 of the first connecting part 51 has a base 62 and a convex body 65 including a projection 66. Figure 5 is an exploded perspective view illustrating the mounting structure of the convex part 61 to the exterior 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 disc shape. The pole 64 extends in the thickness direction of the plate 63. One end of the pole 64 is fixed approximately in the center of the plate 63 in a plan view. Of the two surfaces of the plate 63 in the thickness direction, the surface opposite to the surface to which the pole 64 is fixed is in contact with the exterior 12 of the first cooler body 1. A cover sheet 67 is placed 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 such that the plate 63 is pressed against the exterior 12. The joining is achieved, for example, by heat welding. In this way, the base 62 is fixed to the exterior 12. As described above, the convex body 65 is fitted into the base 62. In this way, the convex part 61 is attached to the exterior 12.

[0034] Similarly, as shown in Figure 6, the recessed part 71 has a base 72 and a recessed body 75 including a recess 76. Figure 6 is an exploded perspective view illustrating the mounting structure of the recessed part 71 to the casing 12. The recessed body 75 is fitted into the base 72. The projection 66 of the convex 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 disc shape. The pole 74 extends in the thickness direction of the plate 73. One end of the pole 74 is fixed approximately in the center of the plate 73 in a plan view. Of the two surfaces of the plate 73 in the thickness direction, the surface opposite to the surface to which the pole 74 is fixed is in contact with the casing 12 of the first cooler body 1. A cover sheet 77 is placed between the recessed body 75 and the plate 73. The pole 74 passes through the cover sheet 77. The cover sheet 77 covers the plate 73. The cover sheet 77 is joined to the exterior 12 so as to press the plate 73 against the exterior 12. The joining is achieved, for example, by heat welding. In this way, the base 72 is fixed to the exterior 12. As described above, the concave body 75 is fitted into the base 72. In this way, the concave part 71 is attached to the exterior 12.

[0035] The above describes the mounting structure of the protruding part 61 and recessed part 71 of the first connecting portion 51 to the outer casing 12 of the first cooler body 1. The same applies to the mounting structure of the protruding part 61 and recessed part 71 of the second connecting portion 52 to the outer casing 32 of the second cooler body 3.

[0036] Next, the assembly method of the neck cooling device 100 will be explained. Figure 7 is an explanatory diagram illustrating the assembly method of the neck cooling device 100.

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

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

[0039] The cooling agents 11 and 31 are in a solid state at room temperature. At this time, the neck cooling device 100 is in a natural state where the first free ends 21 and 41 and the second free ends 22 and 42 are close to or in contact with each other in the circumferential direction.

[0040] The user grasps the first free ends 21, 41 and the second free ends 22, 42, and separates them from each other. The user passes their neck through the gap between the first free ends 21, 41 and the second free ends 22, 42, and wraps the neck cooler 100 around their neck. Finally, the user releases their hands from the first free ends 21, 41 and the second free ends 22, 42. As a result, the neck cooler 100 returns to its natural state where the first free ends 21, 41 and the second free ends 22, 42 are close to or in contact with each other in the circumferential direction, as shown in Figure 8. Because the neck cooler 100 is formed as a closed annular shape, it fits securely around the neck and prevents it from coming off.

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

[0042] Figure 9 is an explanatory diagram illustrating the state in which a user wears the neck cooler 100 with altered cooling capacity. For example, if the user is a child, or if the user wears the neck cooler 100 on a day that is not extremely hot, the user may want to reduce the cooling capacity of the neck cooler 100. In this case, the user wears only the first cooler body 1 around their neck, as shown in Figure 9. This reduces the contact area of ​​the neck cooler 100 with the user's neck, thereby reducing the cooling capacity of the neck cooler 100.

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

[0044] Since the connector 5 is positioned between the first cooling device body 1 and the second cooling device body 3, the connector 5 is unlikely to be exposed to the outside. As a result, when using the neck cooling device 100, hair is less likely to get tangled in the connector 5.

[0045] Since the connector 5 includes a first connecting portion 51 provided on the first cooler body 1 and a second connecting portion 52 provided on the second cooler body 3, the connector 5 can be integrally held by the first cooler body 1 and the second cooler body 3. As a result, when separating the first cooler body 1 and the second cooler body 3 from each other, the connector 5 does not separate from the first cooler body 1 and the second cooler body 3, making management easier.

[0046] Since multiple connectors 5 are arranged in the circumferential direction of the neck cooler 100, the displacement of the second cooler body 3 relative to the first cooler body 1 during use of the neck cooler 100 is suppressed.

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

[0048] Variant form Figure 10 is a perspective view of a modified neck cooler 200. Figure 11 is a plan view of the first cooler body 1 according to the modified example. Figure 12 is a plan view of the second cooler body 3 according to the modified example. The neck cooler 200 differs from the neck cooler 100 according to the embodiment in the configuration of the connector 205. The following description will focus on the configuration of the neck cooler 200 that differs from the neck cooler 100 according to the embodiment. Note that in the neck cooler 200, reference numerals that are the same as those in the neck cooler 100 according to the embodiment have the same configuration as the neck cooler 100 according to the embodiment, so their explanation will be omitted.

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

[0050] The first connecting portion 251 is provided on the opposing surface of the first cooler body 1 that faces the second cooler body 3. Specifically, as shown in Figure 13, the first connecting portion 251 is covered by a cover sheet 267 and sandwiched between the outer casing 12 of the first cooler body 1 and the cover sheet 267. Figure 13 is an exploded perspective view illustrating the mounting structure of the first connecting portion 251 to the outer casing 12. The cover sheet 267 is joined to the outer casing 12. The joining is achieved, for example, by heat welding.

[0051] The second connecting portion 252 is provided on the opposing surface of the second cooler body 3 that faces the first cooler body 1. Specifically, the second connecting portion 252, like the first connecting portion 251, is covered by a cover sheet and sandwiched between the outer casing 32 of the second cooler body 3 and the cover sheet. The cover sheet is joined to the outer casing 32. The joining is achieved, for example, by heat welding.

[0052] More specifically, as shown in Figure 11, the magnetic poles of adjacent first connecting portions 251 in the circumferential direction are different from each other. In other words, when viewed from the axial direction, first connecting portions 251 with north poles and first connecting portions 251 with south poles are arranged alternately in the circumferential direction. Note that the magnetic poles on the front and back sides of the first connecting portions 251 are different.

[0053] As shown in Figure 12, the magnetic poles of adjacent second connecting portions 252 in the circumferential direction are different. That is, when viewed from the axial direction, north pole second connecting portions 252 and south pole second connecting portions 252 are arranged alternately in the circumferential direction. Note that the magnetic poles on the front and back sides of the second connecting portion 252 are different.

[0054] In the first connecting portion 251 and the second connecting portion 252, which are connected to each other, the magnetic poles of the first connecting portion 251 and the magnetic poles of the second connecting portion 252 are different. That is, the north pole of the first connecting portion 251 corresponds to the south pole of the second connecting portion 252, and the south pole of the first connecting portion 251 corresponds to the north pole of the second connecting portion 252. With this configuration, when the second cooler body 3 is axially superimposed on the first cooler body 1 such that the first connecting portion 251 and the second connecting portion 252 face each other in the axial direction, the second cooler body 3 is detachably connected to the first cooler body 1 by the magnetic force of the first connecting portion 251 and the second connecting portion 252.

[0055] In the neck cooler 200, since the first connecting portion 251 and the second connecting portion 252 are magnets, the first connecting portion 251 and the second connecting portion 252 are attracted to each other by magnetic force, making it easy to attach and detach the first cooler body 1 and the second cooler body 3. Specifically, the first cooler body 1 and the second cooler body 3 can be connected without having to press them in opposite directions. More specifically, since the first connecting portion 251 and the second connecting portion 252 are magnets, the first cooler body 1 and the second cooler body 3 can be connected simply by bringing the second cooler body 3 closer to the first cooler body 1, without having to press the second cooler body 3 toward the first cooler body 1.

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

[0057] In addition, since the first connecting portion 251 and the second connecting portion 252 are magnets, when using the neck cooling device 200, 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, and blood flow system of the neck, regulating the biomagnetic field and bioelectric current. In this particular example, the magnetic poles of the circumferentially adjacent first connecting portion 251 are different from each other, and the magnetic poles of the circumferentially adjacent second connecting portion 252 are different from each other. As a result, the magnetic force extends 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.

[0058] Other embodiments As described above, the embodiments described herein have been presented as examples of the technology disclosed in this application. However, the technology in this disclosure is not limited thereto and can be applied to embodiments that have been modified, replaced, added, or omitted as appropriate. Furthermore, it is possible to combine the components described in the embodiments above to create new embodiments. In addition, the components described in the attached drawings and detailed description may include not only components essential for solving the problem, but also components that are not essential for solving the problem, in order to illustrate the technology. Therefore, the mere presence of such non-essential components in the attached drawings and detailed description should not be immediately assumed to mean that those non-essential components are essential.

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

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

[0061] For example, the external shape of the outer casing 12 of the first cooler body 1 is not limited to the shape described above. The arch portion 20 only needs to be curved overall and may include straight portions. The first free end 21 does not include the first straight portion 24 and may be curved. The second free end 22 does not include the second straight portion 25 and may be curved. The same applies to the external shape of the outer casing 32 of the second cooler body 3. The external shape of the outer casing 12 of the first cooler body 1 may differ from the external shape of the outer casing 32 of the second cooler body 3. For example, the external shape of the outer casing 32 of the second cooler body 3 may be formed only from the arch portion 40 without having the first free end 41 and the second free end 42. In this case, the second cooler body 3 does not need to be wrapped around the neck.

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

[0063] The connector 5 may be a single component without including the first connecting portion 51 and the second connecting portion 52. For example, the connector 5 may be a band that bundles the first cooler body 1 and the second cooler body 3 together, and when separating the first cooler body 1 and the second cooler body 3 from each other, the connector 5 may be separated from the first cooler body 1 and the second cooler body 3.

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

[0065] The number and arrangement of the connectors 5 are not limited. 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 a convex part 61. In this case, the second connecting portion 52 may have only a concave part 71. For example, the first connecting portion 51 may have only a concave part 71. In this case, the second connecting portion 52 may have only a convex part 61.

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

[0068] In the modified cooling device 200, the magnetic poles of adjacent first connecting portions 251 in the circumferential direction may be the same, and the magnetic poles of adjacent second connecting portions 252 in the circumferential direction may also be the same.

[0069] [Aspect] The above-mentioned embodiment is a specific example of the following embodiment.

[0070] (Aspect 1) The neck cooling devices 100,200 are neck cooling devices 100,200 that are wrapped around the neck of a living person, and comprise 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 axis A and superimposed on the first cooling device body 1 in the direction of the axis A, and a connector 5,205 that detachably connects the first cooling device body 1 and the second cooling device body 3 to each other.

[0071] With this configuration, the connecting members 5,205 allow the first cooler body 1 and the second cooler body 3 to be connected, and the first cooler body 1 to be used alone, and the configuration can be changed between these two states. The neck coolers 100,200 in the state where the first cooler body 1 and the second cooler body 3 are connected have a higher cooling capacity than the neck coolers 100,200 in the state where only the first cooler body 1 is used. In this way, the cooling capacity of the neck coolers 100,200 can be changed.

[0072] (Aspect 2) In the neck cooling devices 100, 200 described in Embodiment 1, the second cooling device body 3 is wrapped around the neck.

[0073] With 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, thus enhancing the cooling effect on the neck.

[0074] (Aspect 3) In the neck cooling devices 100, 200 described in Embodiment 1 or Embodiment 2, the connecting members 5, 205 are positioned between the first cooling device body 1 and the second cooling device body 3.

[0075] With this configuration, the connectors 5,205 are less likely to be exposed to the outside, so when using the neck coolers 100,200, hair is less likely to get tangled in the connectors 5,205.

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

[0077] With this configuration, the connector 5,205 can be integrally held by the first cooler body 1 and the second cooler body 3. As a result, when separating the first cooler body 1 and the second cooler body 3 from each other, the connector 5,205 does not separate from the first cooler body 1 and the second cooler body 3, making management easier.

[0078] (Appendix 5) In the neck cooling device 100, 200 described in any one of embodiments 1 to 4, the connecting members 5, 205 are arranged in multiple locations in the winding direction of the neck cooling device 100, 200.

[0079] This configuration prevents the second cooling device body 3 from shifting relative to the first cooling device body 1 while the neck cooling devices 100 and 200 are in use. [Explanation of Symbols]
