[0009] Hereinafter, an embodiment of a cooling tool according to the present disclosure will be described with reference to the drawings. (Embodiment 1) The cooling device 10 of the embodiment shown in Fig. 1 is attached to a predetermined location to provide cooling, and includes a cooling unit 20 that performs cooling, and an attachment unit 30 for attaching the cooling unit 20 to the predetermined location. The attachment units 30 are detachably connected to each other via magnetic force, allowing the cooling unit 20 to be attached to the predetermined location. In other words, the attachment units 30 are detachable, allowing them to be connected to or disconnected from each other.

[0010] The cooling section 20 is preferably configured to have elasticity and / or stretchability, and to be capable of at least one of bending, flexing, and elastic deformation. The cooling unit 20 also includes a cooling member 20'. That is, the cooling member 20' includes a cooling material 21, and the cooling material 21 is in a gel state. The cooling unit 20 includes a storage section 22 for storing a cooling member 20', that is, a cooling material 21. The cooling material 21 has a shape that extends in the left-right direction (direction along the arrow LR) as shown by the dotted line in Figure 1, and has a recessed portion 21a that is recessed inward at the center portion 20c in the left-right direction of the cooling section 20.

[0011] Specifically, the cooling material 21 has a recessed portion 21a recessed in the vertical direction at the end in the vertical direction (direction along the arrow UD) of the center portion in the horizontal direction, and protrusions 21b protruding in the vertical direction are provided on both left and right sides of the recessed portion 21a. The recessed portion 21a is recessed in a curved shape, and the protrusions 21b protrude in a curved shape. Specifically, this curved shape is an arc shape. Furthermore, the cooling material 21 is a colloidal solution that has solidified into a semi-solid or solid state, but it has elasticity and / or stretchability and is easily deformable. Specifically, the cooling material 21 can be deformed by being folded in half in the left-right direction at the position of the recessed portion 21a, and can maintain this deformed state. Furthermore, it is more preferable that the cooling material 21 does not solidify even when cooled.

[0012] Furthermore, the cooling material 21 is preferably formed to a thickness of 10 mm or less. More preferably, the cooling material 21 is formed to a thickness of 5 mm. That is, the gel cooling material 21 is preferably thin, lightweight, and soft. As long as the cooling material 21 has a shape with a recessed portion 21a in the center in the left-right direction, the shape of the protruding portion 21b may be a polygonal shape other than a curved shape.

[0013] The storage section 22 that stores the cooling material 21 is bag-shaped and made of fabric. The fabric that forms the storage section 22 preferably has antibacterial properties. In addition, the portion of the storage section 22 that forms the left-right central portion 20c of the cooling section 20 is strip-shaped and extends in the left-right direction (direction along the arrow LR) with a constant width, and the portions that form the left and right side end portions 20d of the cooling section 20 are curved and formed into an arc-like shape.

[0014] The peripheral edge of the storage section 22 is sealed via bias tape 22a. The bias tape 22a is stretchable and can seal while preventing damage to the peripheral edge of the storage section 22. The peripheral edge of the storage section 22 can also be sealed by simply sewing or by other sealing methods such as thermocompression. The storage section 22 also includes a tag section 22b, on which, for example, a name can be written.

[0015] Furthermore, it is preferable that the storage section 22 is made of a cool-to-the-touch material. This cool-to-the-touch material is a material that provides a cool feeling when it comes into contact with the skin, and includes at least one of nylon, polyurethane, linen, silk, rayon, and polyester, and is a material that has high thermal conductivity and thermal diffusivity and feels smooth against the skin.

[0016] Furthermore, as shown in FIG. 1, the cooling section 20 is formed based on the shape of the storage section 22 such that the central portion 20c in the left-right direction (direction along the arrow LR) is a strip-like portion extending in the left-right direction with a constant width, and the left and right side end portions 20d, 20d are curved and rounded in an arc shape.

[0017] The mounting parts 30 are provided so as to protrude like ears to the left and right from both left and right end parts 20d, 20d of the cooling part 20, and have a right mounting part 31 provided at the right end part 20d and a left mounting part 32 provided at the left end part 20d, and can be mounted in a predetermined location by connecting the right mounting part 31 and the left mounting part 32 to each other. In detail, the right mounting part 31 and the left mounting part 32 are formed so as to protrude in a band-like shape to the left and right from the center in the up-down direction of both left and right end parts 20d of the cooling part 20, and the corners of the band-like shape are formed in a curved shape.

[0018] Various configurations can be used to connect the two mounting parts 31, 32, but in this embodiment, as described above, the cooling part 20 can be mounted in a predetermined location by detachably connecting them to each other via magnetic force. Specifically, the right-side mounting part 31 and the left-side mounting part 32 have magnetic bodies 31a and 32a that attract each other by magnetic force. Therefore, when the right-side mounting part 31 and the left-side mounting part 32 are overlapped, the magnetic bodies 31a and 32a attract each other and connect to each other, allowing the cooling unit 20 to be mounted in a predetermined location. Also, by separating the right-side mounting part 31 and the left-side mounting part 32 so that the magnetic bodies 31a and 32a are no longer attracted to each other, the connection between them is released, and the cooling unit 20 can be removed from the predetermined location.

[0019] Both of the magnetic bodies 31a and 32a may be magnets, or one may be a magnet and the other may be a ferromagnetic body such as iron. When both magnetic bodies 31a and 32a are magnets, the north and south poles are arranged to attract each other when right-side mounting part 31 and left-side mounting part 32 are overlapped. Specifically, when cooling part 20 is bent in the left-right direction around central part 20c and both mounting parts 31 and 32 are overlapped, the north and south poles of the magnets are arranged to face each other and attract each other. In addition to using the magnetic bodies 31a and 32a, the attachment part 30 can also use known connecting structures such as a hook-and-loop fastener, a button and hole, a snap button, or a hook.

[0020] The right and left mounting portions 31, 32 are configured by holding magnetic bodies 31a, 32a in holding portions 31b, 32b. The holding portions 31b and 32b wrap and hold the magnetic bodies 31a and 32a.

[0021] That is, the holding portions 31b, 32b are formed from a fabric that wraps the magnetic materials 31a, 32a. The fabric that forms the holding portions 31b, 32b is formed continuously with the fabric that forms the storage portion 22. Therefore, the holding portions 31b, 32b are formed from an antibacterial and cool-to-the-touch material. The edges of the holding portions 31b, 32b are sealed via the bias tape 22a. That is, the bias tape 22a that seals the edges of the holding portions 31b, 32b is formed continuously with the bias tape 22a that seals the edges of the storage portion 22.

[0022] When the holding portions 31b and 32b are formed using fabric, it is preferable to form them continuously with the fabric that forms the storage portion 22, as this saves manufacturing effort, but they may also be separate from the storage portion 22. 2 includes, as the mounting portion 30, a right mounting portion 331 and a left mounting portion 332 that are separate from the storage portion 22. The mounting portions 331 and 332 may be holders 31b and 32b that hold the magnetic bodies 31a and 32a. In addition, the mutual connection between the right-side mounting portion 31 and the left-side mounting portion 32 shown in Figure 1 and the right-side mounting portion 331 and the left-side mounting portion 332 shown in Figure 2 can also be achieved using a configuration other than connection by the attractive force of the magnetic bodies 31a and 32a. For example, the connection between both attachment parts 31 and 32 and the connection between both attachment parts 331 and 332 may be made by a hook and loop fastener, a button and hole, a snap button, a hook or a snap fastener, or the like. 3, in the cooling device 10b, the cooling member 20' includes an ice pack 20'', which may be in a gel form. The ice packs 20'' are provided on both the left and right sides and include a first ice pack 20A'' and a second ice pack 20B''. That is, the storage section 22 is provided on both the left and right sides and includes a first storage section 22A and a second storage section 22B. The left end side of the storage section 22A is a first insertion section 22A' into which the first ice pack 20A'' can be inserted, and the first insertion section 22A' is openable so that the first ice pack 20A'' can be inserted. The right end side of the second storage section 22B is a second insertion section 22B' into which the second ice pack 20B'' can be inserted, and the second insertion section 22B' is openable so that the second ice pack 20B'' can be inserted. A blocking portion 22C is formed in the middle portion in the left-right direction between the first storage portion 22A and the second storage portion 22B so as to separate the first storage portion 22A from the second storage portion 22B.

[0023] The cooling devices 10, 10a, 10b have their attachment parts 30 detachably connected to one another via magnetic force, so that the cooling parts 20 can be attached to predetermined locations on the human body HB (see FIG. 4). Specifically, the predetermined part of the human body HB is at least one of the arms AR, legs, neck NE, face, head, and torso BO, and the device is attached via the attachment part 30 so as to surround the periphery of the predetermined part of the human body HB.

[0024] Furthermore, the cooling devices 10, 10a, and 10b can detachably connect the attachment portion 30 via magnetic force, and the cooling portion 20 can be attached to a predetermined location on the item GO. Specifically, the article GO is clothing CL, the predetermined portion of the clothing CL is an edge portion CE of the clothing CL, and the article GO is attached via the attachment portion 30 so as to sandwich the edge portion CE of the clothing CL. For example, the cooling part 20 can be folded at the position of the recessed part 21a of the cooling material 21, which is the central part 20c in the left-right direction, and attached by sandwiching the edge part CE of the clothing CL with the cooling part 20. The article GO is a collar CO (see FIG. 6), and is attached to the collar CO via an attachment part 30 so as to surround a predetermined part of the collar CO.

[0025] Furthermore, as shown in FIG. 7, a plurality of cooling devices 10, 10a, 10b can be connected via attachment parts 30. That is, by connecting a plurality of cooling tools 10, 10a, 10b via the mounting portion 30, a ring shape can be formed, and the plurality of cooling tools 10, 10a, 10b formed in a ring shape can be mounted so as to surround the periphery of a predetermined location.

[0026] The following is a specific example of the size of the cooling devices 10, 10a, and 10b. For example, it is preferable that the cooling unit 20 and the left and right mounting units 30 form a dimension of 25 cm or more in the left-right direction. Specifically, the cooling unit 20 and the left and right mounting units 30 form a dimension of about 27.5 cm in the left-right direction. Furthermore, it is preferable that the cooling section 20 is formed so that its vertical dimension is 10 cm or more. Specifically, the cooling section 20 is formed so that its vertical dimension is about 10.5 cm.

[0027] (Example of use of the cooling devices 10, 10a, and 10b according to the first embodiment) A specific example of how the cooling devices 10, 10a, and 10b of the first embodiment can be used will be described below. When cooling with the cooling devices 10, 10a, 10b, first, the cooling devices 10, 10a, 10b are placed in a refrigerator or the like to cool the cooling part 20, and then the cooling devices are attached to a predetermined part of the human body HB or a predetermined part of the object GO to be cooled.

[0028] Figure 4 shows an example of cooling the armpit UA of a human body HB using a first cooling device 10(a), which is the cooling device 10, 10a, 10b of embodiment 1, and an example of cooling the arm AR of the human body HB using a second cooling device 10(b), which is the cooling device 10, 10a, 10b of embodiment 1. When cooling the underarm UA with the first cooling device 10(a), the first cooling device 10(a) can be attached via both attachment parts 31, 32 so as to sandwich the underarm edge CE1 of the garment CL.

[0029] Specifically, the cooling section 20 of the first cooling device 10(a) is folded in half in the left-right direction at the position of the central section 20c, which is the position of the recessed section 21a of the cooling material 21. Then, as shown in Fig. 4, one half of the folded cooling section 20 is inserted into the inside of the garment CL from the edge CE1 under the armpit of the garment CL, and the other half of the cooling section 20 is placed on the outside of the garment CL, so that the edge CE1 under the armpit is sandwiched between the cooling section 20. At this time, the magnetic materials 31a, 32a of the right attachment part 31 and the left attachment part 32 overlap and sandwich the edge CE1 of the clothing CL, attracting each other so that the cooling devices 10, 10a, 10b are attached to the edge CE1 of the clothing CL, and in this state the armpit UA of the human body HB is cooled by the first cooling device 10(a).

[0030] Furthermore, when cooling the arm AR of the human body HB using the second cooling device 10(b), as shown in Figure 4, the second cooling device 10(b) can be folded in half in the same manner as the first cooling device 10(a) and attached to the arm BAR via both attachment parts 31, 32. Specifically, the second cooling device 10(b) surrounds the arm BAR of the human body HB, and the right attachment part 31 and the left attachment part 32 are directly overlapped. As a result, the magnetic materials 31a, 32a of the right attachment part 31 and the left attachment part 32 attract each other, and the cooling devices 10, 10a, 10b are attached to the arm AR via both attachment parts 31, 32. Therefore, the arm AR is cooled by the second cooling device 10(b).

[0031] FIG. 5 shows an example in which the vicinity of the posterior cervical region NEB of the neck NE of a human body HB is cooled by cooling devices 10, 10a, and 10b. When cooling the vicinity of the back of the neck NEB of the human body HB with the cooling devices 10, 10a, 10b, the cooling devices 10, 10a, 10b are attached via the attachment parts 31, 32 so as to sandwich the edge CE2 on the back side of the neck NE of the clothing CL.

[0032] Specifically, the cooling section 20 of the cooling device 10, 10a, 10b is folded in half at the position of the central section 20c in the left-right direction, which is the position of the recessed section 21a of the cooling material 21. Then, one half of the folded cooling section 20 is inserted into the inside of the garment CL from the edge CE2 on the back side of the neck NE of the garment CL, and the other half of the cooling section 20 is placed outside the edge CE2, and the edge CE1 on the back side of the neck NE of the garment CL is sandwiched between the cooling section 20. Then, the magnetic materials 31a, 32a of the right attachment part 31 and the left attachment part 32 overlap and sandwich the edge CE2 of the clothing CL, attracting each other so that the cooling devices 10, 10a, 10b are attached to the edge CE2 of the clothing CL, and in this state the cooling devices 10, 10a, 10b cool the area around the posterior neck NEB of the human body HB.

[0033] FIG. 6 shows an example in which the back of the neck D11 of a dog D is cooled by the cooling devices 10, 10a, and 10b. When cooling the back of the neck D11 of the dog D with the cooling devices 10, 10a, 10b, the cooling devices 10, 10a, 10b are attached via both attachment parts 31, 32 so as to surround the back of the neck part COb of the collar CO as the article GO.

[0034] Specifically, the cooling portion 20 of the cooling device 10, 10a, 10b is folded in half at the center portion 20c in the left-right direction, at the position of the recessed portion 21a of the cooling material 21, and is attached via both attachment portions 31, 32 so as to surround the periphery of the back neck portion COb of the collar CO. At this time, the magnetic materials 31a, 32a of the right attachment part 31 and the left attachment part 32 are attracted to each other, and the cooling devices 10, 10a, 10b are attached to the back of the neck part COb of the collar CO, and in this state the back of the neck D11 of the dog D is cooled by the cooling devices 10, 10a, 10b.

[0035] A plurality of cooling devices 10, 10a, 10b according to the first embodiment can be connected via both attachment parts 31, 32. Figure 7 shows an example in which two cooling devices 10, 10a, and 10b of embodiment 1, namely a third cooling device 10(e) and a fourth cooling device 10(f), are connected via their respective mounting portions 31, 31, 32, and 32 to form a ring shape. In this way, the third cooling device 10(e) and the fourth cooling device 10(f) connected in a ring shape can be worn, for example, to surround the neck NE of the human body HB to cool the neck NE, or worn to surround the legs of the human body HB to cool the legs.

[0036] (Effects of the cooling devices 10, 10a, and 10b according to the first embodiment) 1) The cooling devices 10, 10a, and 10b of the first embodiment have a cooling unit 20 that performs cooling, and an attachment unit 30 that can be connected and disconnected to attach and detach the cooling unit 20 to a predetermined location. Therefore, the cooling device 10, 10a, and 10b of the first embodiment can be attached to a predetermined location, such as the arm AR or neck NE of a human body HB, clothing CL as an item GO, or a collar CO of a dog D, and the predetermined location can be cooled by the cooling unit 20. Therefore, the cooling devices 10, 10a, and 10b of the first embodiment can be used for cooling a variety of purposes.

[0037] 2) The mounting part 30 is provided on both left and right end parts 20d, 20d of the cooling part 20, and has a right mounting part 31 provided on the right end part 20d and a left mounting part 32 provided on the left end part 20d, and is mounted at a predetermined location by connecting the right mounting part 31 and the left mounting part 32 to each other. Therefore, by connecting the right mounting portion 31 and the left mounting portion 32 to each other, the cooling devices 10, 10a, 10b can be easily mounted in predetermined locations.

[0038] Furthermore, the mounting parts 30 can be detachably connected to each other via magnetic force, thereby allowing the cooling part 20 to be mounted in a predetermined location. In other words, the mounting parts 30 are detachable, so that they can be connected or disconnected to each other. Specifically, the right mounting part 31 and the left mounting part 32 of the mounting part 30 have magnetic bodies 31a, 32a that attract each other by magnetic force, and by connecting them to each other via magnetic force, the cooling part 20 can be mounted in a predetermined location, and by disconnecting the magnetic bodies 31a, 32a that attract each other by magnetic force, the cooling part 20 can be removed from the predetermined location.

[0039] Therefore, the cooling devices 10, 10a, and 10b of the first embodiment are even easier to attach and detach, and have excellent operability for attachment and detachment. Moreover, since the holding portions 31b and 32b are configured to wrap and hold the magnetic bodies 31a and 32a, the magnetic bodies 31a and 32a are less likely to be damaged. In addition, by connecting a plurality of units via both mounting portions 31 and 32, it is possible to form a ring and mount it so as to surround the periphery of a predetermined location. Therefore, the cooling devices 10, 10a, and 10b of the first embodiment can be attached to a wider variety of locations and can be used for cooling in a variety of ways.

[0040] 3) The cooling section 20 has elasticity and / or stretchability, and is configured to be capable of at least one of bending, flexing, and elastic deformation. Therefore, when the cooling unit 20 is attached to a specified location, it deforms according to the shape of the specified location, thereby improving the attachment performance to a variety of locations. In addition, the contact area is secured, resulting in high cooling performance and stable attachment, resulting in an excellent feeling when attached.

[0041] 4) The cooling portion 20 includes the cooling material 21, and the cooling material 21 is in a gel state. Therefore, the cooling section 20 can be easily deformed as described above, and the effects of high cooling performance and excellent comfort when worn are enhanced.

[0042] Furthermore, the cooling material 21 has a shape that extends in the left-right direction and has a recessed portion 21a that is recessed inward at a central portion 20c in the left-right direction. Therefore, it is easy to fold the cooling portion 20 in half at the position of the recessed portion 21a in the central portion 20c. This makes it easy to attach the cooling devices 10, 10a, 10b to the edges CE1, CE2 of thin clothing CL, providing excellent wearability. Reducing the thickness of the cooling part 20 also contributes to this wearability.

[0043] Furthermore, since the left and right ends of the cooling unit 20 are curved and arc-shaped, it is less likely to get caught on the human body HB or clothing CL when attached to the human body HB or clothing CL, allowing for stable attachment and preventing damage to the cooling unit 20 due to getting caught. Furthermore, the cooling material 21 is formed to a thickness of 10 mm or less, preferably 5 mm, so that the cooling devices 10, 10a, 10b of the first embodiment can be made lighter and the cooling unit 20 can be more easily deformed when attached to a predetermined location, thereby enhancing the effects of the high cooling performance and excellent feeling when attached. In addition, when a thin, lightweight, and soft gel cooling material 21 is used, it can be used without discomfort to cool specific areas of babies and women with sensitive skin, and can also be used without discomfort when placed on a pillow when sleeping.

[0044] 5) The cooling unit 20 includes a storage unit 22 for storing the cooling material 21. Therefore, the cooling material 21 can be stably held.

[0045] 6) The storage section 22 is made of a cool-to-the-touch material and has antibacterial properties, so when it comes into contact with the human body HB, it provides a cool feeling and can inhibit the growth of bacteria and microorganisms.

[0046] 7) Unlike the shape of the cooling material 21 having a recess 21a at the center 20c in the left-right direction, the storage section 22 is a strip-like shape that extends in the left-right direction with a constant width at the center 20c. Therefore, when folding the cooling section 20 at the center 20c, it is easy to fold, is easy to use, and has a simple shape that is easy to manufacture. Furthermore, since both left and right ends of the storage section 22 are curved, they are less likely to get caught on the human body HB or the article GO when attached to the human body HB or the article GO, thereby improving durability. In addition, the periphery of the storage section 22 is sealed via a bias tape 22a. Therefore, the cooling devices 10, 10a, and 10b of the first embodiment can seal the periphery of the storage section 22 while preventing damage thereto.

[0047] (Embodiment 2) Cooling device 200 of embodiment 2 shown in Fig. 8 includes cooling unit 220 that performs cooling and mounting unit 230 for mounting cooling unit 220 in a predetermined location, with cooling unit 220 extending downward and having a curved U-shape at its lower end. The curved shape of the lower end is an arc that protrudes downward. The cooling portion 220 includes the cooling material 21, and the cooling material 221 is in a gel state.

[0048] The cooling section 220 is formed to extend 20 cm or more in both the vertical and horizontal directions. More specifically, the cooling section 220 is formed to extend 23 cm in the vertical direction and 22 cm in the horizontal direction.

[0049] As in the first embodiment, cooling unit 220 has elasticity and / or stretchability, and is configured to be capable of at least one of curving, bending, and elastic deformation, and is configured by storing cooling material 221 in storage unit 222. Furthermore, cooling material 221 stored in storage unit 222 of cooling unit 220 is in a gel state, and is formed in the same shape as cooling unit 220 and storage unit 222.
