Description

Canister and cooling device using the canister

[0001] The present disclosure relates to a canister and a cooling device using the canister, and more particularly to a canister for cooling a target area such as the face and a cooling device using the canister. CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority from Patent Application No. 2024-088396, filed May 30, 2024, the entire contents of which are incorporated herein by reference.

[0003] For example, a cooling sheet has been developed that cools a heated area of ​​a user by contacting the affected area to remove heat (see Patent Document 1). The cooling sheet utilizes the heat-absorbing properties of a cooling gel to remove heat from the affected area. The cooling sheet is a sheet for an eye mask that contains cooling gel and is attached to the face.

[0004] Also proposed is a device for cooling an object in contact with a heat dissipation part, in which a hydrogen storage alloy is installed and hydrogen is released from the heat dissipation part (see Patent Document 2).

[0005] Utility Model Registration No. 3240961 Japanese Patent Laid-Open No. 3-191267

[0006] However, cooling sheets that use cooling gel lose their cooling effect in a short period of time, making it difficult to maintain the cooling state of the cooling sheet for a predetermined period of time. Also, while the cooling effect can be maintained for a long period of time by increasing the volume of cooling gel, this makes the cooling sheet heavier, making it difficult to wear the cooling sheet stably, especially on the face.

[0007] On the other hand, in the above-mentioned device, the desired cooling time is set by adjusting the capacity of the heat dissipation unit containing the hydrogen storage alloy. In this case, when hydrogen is released from the heat dissipation unit, part of the hydrogen storage alloy may turn into powder, and the powder may be released from the inside to the outside. Therefore, measures such as attaching a filter to the outlet of the heat dissipation unit are necessary. However, the filter is usually fixed to the heat dissipation unit. Therefore, if the filter deteriorates over time or becomes clogged, it is necessary to replace the entire filter and heat dissipation unit, which increases costs.

[0008] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a canister and a cooling device using a canister that has a lightweight structure, can be attached to a target area such as the face, can cool the target area such as the face uniformly for a predetermined period of time, and can be reused multiple times.

[0045] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0046] Fig. 1 is a perspective view of a canister 100 of the present disclosure. Fig. 2 is a partial cross-sectional side view of a nozzle portion 102 of the canister 100 of the present disclosure.

[0047] The canister 100 comprises a metal container 101 containing a hydrogen storage alloy, and a nozzle portion 102. While the metal container 101 of the canister 100 is preferably filled with the hydrogen storage alloy, the hydrogen storage alloy may be contained in other ways, for example, by being contained in a spiral shape. Hydrogen leaked from the hydrogen storage alloy is stored in the metal container 101, and the stored hydrogen is ejected by a predetermined operation, for example, by pressing a push button 108 on the nozzle portion 102.

[0048] When hydrogen is absorbed, the hydrogen storage alloy expands by approximately 10%. Furthermore, if the canister 100 is filled with too much hydrogen storage alloy, internal pressure is generated, making the filter 110 (described later) more susceptible to clogging. Furthermore, the metal container 101 itself may expand due to internal pressure. Therefore, it is preferable to fill the metal container 101 with the hydrogen storage alloy to approximately 90%. The hydrogen storage alloy filling ratio is not limited to 90%; it may be approximately 70% or 80%, but in this case, the hydrogen storage capacity decreases. Furthermore, as the voids within the metal container 101 become larger, the amount of hydrogen that escapes increases, increasing the risk of danger. Therefore, to ensure the safety of the canister 100 and maximize the hydrogen storage capacity, it is preferable to fill the metal container 101 with approximately 90% hydrogen storage alloy. However, as described above, approximately 70-80% or 80-90% may also be used.

[0049] The metal container 101 may have various shapes, but is preferably substantially cylindrical. The metal container 101 is preferably made of a material with high thermal conductivity, such as aluminum, gold, silver, copper, graphene, stainless steel, iron, titanium, or brass.

[0050] The nozzle portion 102 is disposed at one end of the metal container 101. For example, when the metal container 101 has a substantially cylindrical shape and is stood upright with its bottom surface facing downward, the nozzle portion 102 is disposed at the upper end of the metal container 101.

[0051] The nozzle portion 102 has a cover member 105 fixed to the metal container 101. A check valve 106 attached to the metal container 101 is disposed inside the cover member 105. A push button 108, which is a button for releasing hydrogen gas, is disposed above the check valve 106 via an elastic member such as a spring 107. A nozzle 109 communicating with the interior of the cover member 105 is formed on the push button 108.

[0052] A portion of the push button 108 protrudes from the cover member 105 to the outside. When the push button 108 is pushed down in the direction of the arrow shown in Figure 2, the check valve 106 opens, connecting the inside and outside of the metal container 101. Hydrogen gas is then released from the hydrogen storage alloy inside the metal container 101 to the outside through the nozzle 109. The check valve 106 prevents outside air, moisture, etc. from flowing into the metal container 101, thereby preventing functional deterioration of the hydrogen storage alloy inside the metal container 101. The nozzle portion 102 may have any shape.

[0053] 3 is a side view of another embodiment of the canister 100. In the canister 100 of this embodiment, the push button 108 shown in FIG.

[0054] When hydrogen gas is to be released from the canister 100, a push button 108 is fitted into the cover member 105, and the check valve 106 is pushed down in the direction of the arrow via the push button 108, thereby releasing the hydrogen gas from the canister 100. When the canister 100 is not in use, the push button 108 can be detached from the cover member 105 to prevent the canister 100 from accidentally releasing hydrogen gas. In this case, the push button 108 is connected to the metal container 101 using a wire 103 to prevent it from being lost. Note that the connecting member connecting the push button 108 to the metal container 101 is not limited to the wire 103, and various other members can be used. While connecting the metal container 101 and the push button 108 is preferable from the viewpoint of preventing the push button 108 from being lost, this connection is not necessary, and the push button 108 may be separated from the metal container 101.

[0055] Furthermore, a magnet may be built into either the cover member 105 or the push button 108, and a magnetic material may be applied to or included in the other, thereby preventing loss without connection.

[0056] Figure 4 shows a cross-sectional side view of an embodiment in which a filter 110 is disposed in the nozzle portion 102 of the canister 100. Figure 4(a) shows a state in which the push button 108 has been removed from the cover member 105, and Figure 4(b) shows a cross-sectional side view in which the push button 108 has been attached to the cover member 105. Figure 5 is a perspective view of the canister 100 shown in Figure 4 in which the nozzle portion 102 to which the filter 110 is connected has been removed.

[0057] In this case, the nozzle portion 102 includes a cover member 105 , a push button 108 , and a filter 110 .

[0058] The cover member 105 has a joint portion 1051 and a cover portion 1052, and the push button 108 can be inserted into the joint portion 1051. The push button 108 is detachable from the cover member 105, and it is preferable to connect the push button 108 to the cover member 105 using a wire 103 or the like to prevent it from being lost. If the push button 108 and the cover member 105 are not connected, it is preferable to use a magnet or the like to prevent it from being lost.

[0059] Furthermore, a flow path for hydrogen gas ejected from the metal container 101 is formed inside the joint 1051, and a flow path opening / closing control unit such as a valve 1053 is provided along the path of the flow path to close the flow path. The flow path opening / closing control unit is preferably a valve 1053, but is not limited to the valve 1053 as long as it has a configuration that can control the opening and closing of the flow path. Below, the case of the valve 1053 will be described as an example of a flow path opening / closing control unit. The valve 1053 uses an elastic body such as a spring, and when the push button 108 is not inserted into the joint 1051, the flow path is closed by the bias of the elastic body such as the spring. When the push button 108 is inserted into the joint 1051, the valve is pushed downward by the push button 108, opening the flow path. This allows hydrogen gas to be ejected when the push button 108 is inserted into the joint 1051. Furthermore, when the push button 108 is removed from the joint 1051, the valve in the joint 1051 returns to its original position due to the bias of an elastic body such as a spring, closing the flow path and preventing the release of hydrogen gas. The valve 1053 in the joint 1051 may have any configuration as long as it opens the flow path when the push button 108 is inserted and closes the flow path when the push button 108 is removed. For example, it may be a ball valve, a needle valve, or the like.

[0060] The nozzle portion 102 is detachably inserted into the container opening 111 of the metallic container 101. In this case, a joint portion 1051 of the cover member 105 of the nozzle portion 102 is crimped or screwed to the container opening 111 to prevent hydrogen gas from being released from the metallic container 101. The container opening 111 is formed with a female or male thread, and the portion of the joint portion 1051 that screws into the container opening 111 is preferably formed with a male or female thread so that the nozzle portion 102 can be screwed to the container opening 111. A filter 110 is connected to the lower end of the joint portion 1051 of the cover member 105 of the nozzle portion 102. The filter 110 prevents hydrogen storage alloy powder (including fine powder with particle sizes on the order of μm) contained in the metallic container 101 from leaking out, and allows only the hydrogen gas sealed in the metallic container 101 to pass through. The filter 110 may also be attached to the nozzle portion 102 (joint portion 1051) in a detachable manner.

[0061] A hydrogen gas flow path is formed inside the push button 108, connecting the nozzle 109 with the flow path of the joint 1051, and a check valve 106 is formed on this path. By providing the check valve 106 on the path of the flow path of the push button 108, it is possible to prevent air and the like from outside the canister 100 from being drawn into the metal container 101 through the nozzle 109, even when the push button 108 is inserted into the joint 1051.

[0062] The cover portion 1052 of the cover member 105 is attached to the outer portion of the joint portion 1051 of the metal container 101 and is movable along the outer surface of the joint portion 1051 .

[0063] When the push button 108 is inserted into the joint portion 1051, the push button 108 engages with the cover portion 1052, preventing the push button 108 from coming off due to the pressure of the hydrogen gas ejection. A groove 1081 is formed on the outer side of the push button 108, and a protrusion 1054 formed of a metal ball or the like held by a spring is formed on the inner side of the cover portion 1052. The protrusion 1054 of the cover portion 1052 fits into the groove 1081 of the push button 108, thereby locking the push button 108 to the cover portion 1052. To remove the push button 108, the cover portion 1052 is moved in a predetermined direction, for example, downward, to release the engagement between the push button 108 and the cover portion 1052, allowing the push button 108 to be removed from the joint portion 1051.

[0064] In the above description, the engaging portion between the cover member 105 and the push button 108 is configured by providing the protrusion 1054 on the inner surface of the cover portion 1052 and the groove 1081 on the outer surface of the push button, but the engaging portion may also be configured by providing a groove on the inner surface of the cover portion 1052 and a protrusion such as a metal ball held by a spring on the outer surface of the push button 108. The engaging portion may also be configured in other ways.

[0065] In conventional canisters containing hydrogen storage alloys, the filter is attached to the metal container body, so even if the filter becomes clogged, it cannot be removed from the metal container, and as a result, the canister itself must be discarded.

[0066] However, as in the canister 100 of Figures 4 and 5, by arranging the filter 110 on the nozzle portion 102 side of the canister 100 and making the nozzle portion 102 and the metal container 101 detachable, even if the filter 110 becomes clogged, the nozzle portion 102 can be removed from the metal container 101 and the nozzle portion 102 or the filter 110 can be replaced.

[0067] In the canister 100 of the present disclosure, the metal container 101 is preferably made of a highly thermally conductive material such as aluminum, gold, silver, copper, graphene, stainless steel, iron, titanium, or brass, as described above. However, a portion of the metal container 101, for example, a portion or all of the side surfaces and / or bottom surface, may be made of a magnetic material such as iron, nickel, or cobalt. By using a magnetic material for a portion of the metal container 101, for example, a portion or all of the side surfaces and / or bottom surface, the canister 100 can be fixed to the cooling device by magnetic force when attached to various cooling devices, as described below. Figure 6 schematically shows an example of the canister 100 in Figure 3, where the lower side surfaces and bottom surface are made of iron (a magnetic material).

[0068] Furthermore, instead of constructing a portion of the metal container 101 from a magnetic material, a magnetic material such as iron may be attached to the side and / or bottom surface of the metal container 101 by adhesive or the like, so that the metal container 101 can be fixed to the cooling device by magnetic force.

[0069] In the above-described configuration, either the canister having the configuration shown in FIGS. 1 to 3 or the canister having the configuration shown in FIGS. 4 to 6 can be applied as the canister used in each of the following embodiments.

[0070] Next, an embodiment in which the canister 100 of the present disclosure is used as a facial cooling device (facial cooling device) will be described below with reference to the drawings.

[0071] 7 is a side view of the canister 100 (canister 16) of the present disclosure used as a facial cooling device (facial cooling device 10) and the facial cooling device 10 attached to the face. Note that, for convenience of explanation, the canister 100 of the present disclosure will be referred to as the canister 16 below, but its configuration may be any of the canisters having the configurations shown in FIGS. 1 to 3 or the canisters having the configurations shown in FIGS. 4 to 6.

[0072] Fig. 8 is a front view of the facial cooling device 10 in an unfolded state. Fig. 9(A) is a cross-sectional view taken along line IIIA-IIIA in Fig. 8, and Fig. 9(B) is a cross-sectional view taken along line IIIB-IIIB in Fig. 8. Fig. 10 is a side view of the vicinity of the nozzle portion of the canister when used in the facial cooling device 10. Fig. 11 is a side view of the canister when used in the facial cooling device 10. Fig. 12 is a cross-sectional side view of the canister when used in the facial cooling device 10. Fig. 13 is an enlarged view of the vicinity of the nozzle portion of the canister when used in the facial cooling device 10.

[0073] <Description of the Configuration of the Facial Cooling Device 10> The facial cooling device 10 includes a mounting belt 14, canisters 16a and 16b, a cooling plate 20, and a thermally conductive sheet 22.

[0074] The wearing belt 14 is longer than the outer periphery of the head 12, and as shown in the cross-sectional views of Figures 9(A) and 9(B), has a two-layer structure in which a urethane layer 26 is bonded to a nylon layer 24. The wearing belt 14 is worn on the head 12. The urethane layer 26 is positioned on the face side when the wearing belt 14 is worn on the head 12. A hook-and-loop fastener 28 is disposed at one longitudinal end of the urethane layer 26. Meanwhile, the surface of the nylon layer 24 to which the urethane layer 26 is not attached is in a raised state. Therefore, when the wearing belt 14 is worn on the head 12, the hook-and-loop fastener 28 is pressed against the raised surface of the nylon layer 24, thereby securing the wearing belt 14 to the head 12.

[0075] The attachment belt 14 has two openings 30 in the center for accessing the eyes and a notch 32 for accessing the nose. Curved portions 34 are formed on both sides of the opening 30 in the attachment belt 14. The curved portions 34 are curved like a bag. When attached to the head 12, the curved portions 34 correspond to both sides of the temporal region. A cooling plate 20 is attached to the urethane layer 26 between the two curved portions 34. The curved portion 34 is surrounded by the urethane layer 26 and a portion of the cooling plate 20. The cooling plate 20 can be made of, for example, a copper plate, an annealed copper plate, or an aluminum plate, which have high thermal conductivity. A composite material that combines copper plate or copper foil with high thermal conductivity can also be used. A thermally conductive sheet 22 is attached to the surface of the cooling plate 20. The thermally conductive sheet 22 is placed on the target area. The thermally conductive sheet 22 can be made of, for example, silicone rubber mixed with a thermally conductive filler. A replaceable antibacterial film 46 is attached to the surface of the thermally conductive sheet 22. The antibacterial film 46 comes into direct contact with the target area, which here refers to the area that the user wishes to cool, such as the face.

[0076] A pair of canisters 16a, 16b (hereinafter referred to as "canisters 16") filled with a hydrogen storage alloy are disposed in each curved portion 34. The canisters 16 have the same configuration as the canister 100 shown in Figures 1 to 6. For convenience of explanation, the configuration of the canister 16 provided in the facial cooling device will be described again.

[0077] Any method can be used to form and fix the curved portion 34, as long as the canister 16 can be inserted into the opening of the curved portion 34. Furthermore, the curved portion 34 does not have to be used as long as the canister 16 can be fixed to the mounting belt 14, and the fixing direction of the canister 16 is not limited to the longitudinal direction of the mounting belt 14, but may be any direction, such as perpendicular or diagonal to the longitudinal direction of the mounting belt 14.

[0078] The canisters 16a, 16b may be fixed to the curved portion 34 with an adhesive. Alternatively, the canister 16 may be a metal container 36 with part or all of the side and / or bottom surfaces formed of or attached to a magnetic material such as iron, or with a magnet or the like attached to part or all of the inner wall surface of the curved portion 34, so that the canister 16 can be detachably attached to the curved portion 34 by magnetic force. When the canister 16 is detachably fixed, it may be fixed by a belt or other method in addition to magnetic force. In this case, it is preferable that the inner diameter of the curved portion 34 and the outer diameter of the metal container 36 are approximately the same.

[0079] In the following description of each embodiment, the canister 16 corresponds to the canister 100, the metal container 36 corresponds to the metal container 101, the nozzle portion 40 corresponds to the nozzle portion 102, the wire 44 corresponds to the wire 103, the antibacterial film 46 corresponds to the antibacterial film 104, the cover member 48 corresponds to the cover member 105, the check valve 50 corresponds to the check valve 106, the spring 52 corresponds to the spring 107, the push button 54 corresponds to the push button 108, the nozzle 56 corresponds to the nozzle 109, the filter 58 corresponds to the filter 110, and the container opening 60 corresponds to the container opening 111.

[0080] 10 corresponds to FIG. 2, FIG. 11 corresponds to FIG. 3, FIG. 12 corresponds to FIG. 4, and FIG. 13 corresponds to FIG. 5, respectively.

[0081] As shown in FIGS. 7 and 8 , the canister 16 is disposed on both sides of the head and includes a metal container 36 filled with a hydrogen storage alloy and a nozzle portion 40. The canister 16 is disposed such that its axis is perpendicular to the longitudinal direction of the mounting belt 14. The metal container 36 has, for example, a substantially cylindrical outer shape. The metal container 36 is fixed to the mounting belt 14 with its outer periphery in contact with the urethane layer 26 and the cooling plate 20, respectively. This fixation may be made non-detachable using an adhesive or the like, or may be made detachable by, for example, attaching a magnetic material to a portion of the side and / or bottom surface of the canister 16 and attaching a magnet to part or all of the inner wall surface of the curved portion 34. When the canister 16 is detachably fixed, it may be fixed by magnetic force, a belt, a spring, or other methods.

[0082] The metal container 36 can be made of a material with high thermal conductivity, such as aluminum, gold, silver, copper, graphene, stainless steel, iron, titanium, or brass.

[0083] The nozzle portion 40 is disposed at the upper end of the metal container 36 when the facial cooling device 10 is worn on the face. The nozzle portion 40 protrudes from the wearing belt 14. The nozzle portion 40 has a cover member 48 fixed to the metal container 36. A check valve 50 attached to the metal container 36 is disposed inside the cover member 48. A push button 54 is disposed above the check valve 50 via a spring 52. The push button 54 is formed with a nozzle 56 that communicates with the interior of the cover member 48. A portion of the push button 54 protrudes from the cover member 48 to the outside. When the push button 54 is pushed down in the direction of the arrow shown in FIG. 10 , the check valve 50 opens, connecting the interior and exterior of the metal container 36. Hydrogen gas is then released from the hydrogen storage alloy inside the metal container 36 to the outside through the nozzle 56. The check valve 50 prevents outside air, moisture, etc. from flowing into the metal container 36, thereby preventing the performance of the hydrogen storage alloy inside the metal container 36 from deteriorating.

[0084] FIG. 11 is a side view of another embodiment of the canister 16. In this embodiment, the canister 16 is configured such that the push button 54 shown in FIG. 10 is detachable from the cover member 48. When hydrogen gas is to be released from the canister 16, the push button 54 is fitted into the cover member 48, and the check valve 50 is pushed down in the direction of the arrow via the push button 54, thereby releasing hydrogen gas from the canister 16. Furthermore, when the facial cooling device 10 is not in use, the push button 54 can be detached from the cover member 48 to prevent accidental release of hydrogen gas from the canister 16. In this case, the push button 54 is connected to the metal container 36 using the wire 44 to prevent loss. Furthermore, a magnet may be built into either the cover member 48 or the push button 54, and a magnetic material may be applied to or embedded in the other to prevent loss without connection.

[0085] Figure 12 shows a cross-sectional side view of an embodiment in which a filter 110 is disposed in the nozzle portion 40 of the canister 16. Figure 12(a) shows a state in which the push button 54 has been removed from the cover member 48, and Figure 12(b) shows a cross-sectional side view in which the push button 54 has been attached to the cover member 48. Figure 13 is a perspective view of the canister 100 shown in Figure 12 in which the nozzle portion 102 to which the filter 110 is connected has been removed.

[0086] In this case, the nozzle portion 40 includes a cover member 48 , a push button 54 , and a filter 110 .

[0087] The cover member 48 has a joint portion 481 and a cover portion 482, and the push button 54 can be inserted into the joint portion 481. The push button 54 is detachable from the cover member 48, and it is preferable to connect the cover member 48 to the wire 44 or the like to prevent the push button 54 from being lost. If the cover member 48 and the push button 54 are not connected, it is preferable to use a magnet or the like to prevent loss.

[0088] A flow path for hydrogen gas ejected from the metal container 36 is formed inside the joint 481, and a valve 483 is provided in the path of the flow path to close the flow path. The valve 483 uses an elastic body such as a spring, and closes the flow path by the bias of the spring when the push button 54 is not inserted into the joint 481. When the push button 54 is inserted into the joint 481, the push button 54 presses the valve downward, opening the flow path. This allows hydrogen gas to eject when the push button 54 is inserted into the joint 481. When the push button 54 is removed from the joint 481, the valve 483 in the joint 481 returns to its original position by the bias of the spring, closing the flow path and preventing the ejection of hydrogen gas. The valve 483 in the joint 481 may have any configuration as long as it opens the flow path when the push button 54 is inserted and closes the flow path when the push button 54 is removed. For example, it may be a ball valve, a needle valve, or the like.

[0089] The nozzle unit 40 is detachably inserted into the container opening 60 of the metal container 36. In this case, the joint 481 of the cover member 48 of the nozzle unit 40 is crimped or screwed to the container opening 60 to prevent hydrogen gas from being released from the metal container 36. The container opening 60 is formed with a female or male thread, and the portion of the joint 481 that screws into the container opening 60 is preferably formed with a male or female thread, allowing the nozzle unit 40 to be screwed to the container opening 60. A filter 58 is connected to the lower end of the joint 481 of the cover member 48 of the nozzle unit 40. The filter 58 prevents the hydrogen storage alloy powder (including fine powder with particle sizes on the order of μm) contained in the metal container 36 from leaking out, and allows only the hydrogen gas sealed in the metal container 36 to pass through. The filter 58 may also be detachably attached to the nozzle unit 40 (joint 481).

[0090] A hydrogen gas flow path is formed inside the push button 54, connecting the nozzle 56 with the flow path of the joint 481, and a check valve 50 is formed on this path. By providing the check valve 50 on the path of the flow path of the push button 54, it is possible to prevent air and the like outside the canister 16 from being drawn into the metal container 36 through the nozzle 56, even when the push button 54 is inserted into the joint 481.

[0091] The cover portion 482 of the cover member 48 is attached to the outer portion of the metal container 36 of the joint portion 481 and is movable along the outer surface of the joint portion 481 .

[0092] When the push button 54 is inserted into the joint portion 481, the push button 54 engages with the cover portion 482, preventing the push button 54 from coming off due to the pressure of the hydrogen gas ejection. A groove 541 is formed on the outer side of the push button 54, and a protrusion 484, such as a metal ball held by a spring, is formed on the inner side of the cover portion 482. The protrusion 484 of the cover portion 482 fits into the groove 541 of the push button 54, thereby locking the push button 54 to the cover portion 482. To remove the push button 54, the cover portion 482 is moved in a predetermined direction, for example, downward, to release the engagement between the push button 54 and the cover portion 482, allowing the push button 54 to be removed from the joint portion 481.

[0093] In the above description, the engagement portion between the cover member 48 and the push button 54 is configured by providing the protrusion 484 on the inner surface of the cover portion 482 and the groove 541 on the outer surface of the push button, but the engagement portion may also be configured by providing a groove on the inner surface of the cover portion 482 and a protrusion such as a metal ball held by a spring on the outer surface of the push button 54. The engagement portion may also be configured in other ways.

[0094] <Explanation of How to Use the Facial Cooling Device 10> A user wearing the facial cooling device 10 on the head 12 will be described. The user wears the facial cooling device 10 with the urethane layer 26 of the attachment belt 14 facing the face and aligning the opening 30 with the eye. The target area where the thermally conductive sheet 22 of the facial cooling device 10 is placed can be, for example, the eyes and / or the area surrounding them. Next, the hook-and-loop fastener 28 is pressed against the nylon layer 24, the ends are connected, and the attachment belt 14 is secured to the head 12. In this case, the thermally conductive sheet 22 abuts against the metal cooling plate 20 via the antibacterial film 46. Therefore, the cooling plate 20 does not directly contact the target area on the face, reducing the risk of user discomfort or metal allergies. A replaceable antibacterial film 46 is attached to the face-facing surface of the thermally conductive sheet 22. Therefore, for example, when another user reuses the facial cooling appliance 10, the antibacterial film 46 can be replaced to avoid hygiene issues.

[0095] After the facial cooling device 10 is attached to the head 12, pressing the push button 54 attached to the nozzle 40 of the canister 16 located at the side of the head opens the check valve 50, and the hydrogen stored in the hydrogen storage alloy in the metal container 36 turns into gas and is released to the outside through the nozzle 56. At this time, the temperature of the metal container 36 drops rapidly due to the release of hydrogen gas. As the temperature of the metal container 36 drops, the temperature of the cooling plate 20 in contact with the metal container 36 also drops, and the temperature of the thermally conductive sheet 22 arranged along the cooling plate 20 also drops. As a result, the target area of ​​the face in contact with the thermally conductive sheet 22 is effectively cooled via the antibacterial film 46. The urethane layer 26 on the face side of the attachment belt 14 prevents condensation on the facial cooling device 10 even if the temperature of the thermally conductive sheet 22 drops rapidly.

[0096] 12 and 13, a filter 58 is disposed inside the metal container 36. When hydrogen gas is released, fine powder may be generated from the contents of the metal container 36, which contains a hydrogen storage alloy. In this case, the filter 58 can prevent the fine powder from being released to the outside.

[0097] Furthermore, there is a concern that the filter 58 may deteriorate or become clogged over time after the canister 16 has been used for a certain period of time. In this case, as shown in Figure 13, the filter 58 can be easily replaced by removing the nozzle portion 40 from the metal container 36.

[0098] 14 is an explanatory diagram of an example of a measurement of temperature change over time on the thermally conductive sheet 22 constituting the facial cooling device 10. In this example, the surface temperature of the thermally conductive sheet 22 was 27.8°C immediately before hydrogen gas was released from the canister 16. However, once the release of hydrogen gas began, the surface temperature of the thermally conductive sheet 22 rapidly dropped to around 10.0°C. After that, the surface of the thermally conductive sheet 22 remained cooled for nearly 30 minutes, after which it slowly rose to a temperature close to that before the release of hydrogen gas. Therefore, it can be seen that the facial cooling device 10 maintains its cooling effect for a long period of time.

[0099] As described above, the facial cooling device 10 for cooling a target area on the face comprises a mounting belt 14 attached to the head 12, a canister 16 containing a hydrogen storage alloy that is fixed to the mounting belt 14 and placed on the side of the head, a cooling plate 20 that is fixed to the mounting belt 14 and in contact with the canister 16, and a thermally conductive sheet 22 that is fixed to the mounting belt 14 and placed on the target area in contact with the cooling plate 20; hydrogen gas is released from the canister 16 to cool the cooling plate, and the target area is cooled via the thermally conductive sheet 22.

[0100] In the facial cooling device 10, the attachment belt 14 has a two-layer structure of a nylon layer 24 and a urethane layer 26, with the urethane layer 26 being disposed on the face side.

[0101] In the facial cooling device 10, the canister 16 includes a metal container 36 that contains a hydrogen storage alloy, and a check valve 50 that releases hydrogen gas from the metal container 36.

[0102] In the facial cooling device 10, the cooling plate 20 is cooled by releasing hydrogen gas from the hydrogen storage alloy filled in the canister 16, and the target area is effectively cooled via the thermally conductive sheet 22. The target area is cooled uniformly for a long period of time. The canister 16 can be refilled with hydrogen and reused multiple times, eliminating waste and causing no adverse environmental impact. The use of the thermally conductive sheet 22 to cool the target area achieves thermal uniformity, rapid cooling, and tracking, while maintaining a cooling state for a long period of time. The facial cooling device 10 also allows for flexible design of the temperature achieved by adjusting the composition and amount of the hydrogen storage alloy and the heat dissipation properties of the container. It also prevents low-temperature burns and minimizes the bulkiness of insulation used to prevent condensation. Furthermore, because the filter 58 is located within the metal container 36 of the canister 16, it can be easily replaced even if it deteriorates over time or becomes clogged.

[0103] Furthermore, the canister 16 may be a metal container 36 in which part or all of the side and / or bottom surfaces are made of or have a magnetic material such as iron attached thereto. In this case, a magnet or the like may be attached to part or all of the inner wall surface of the curved portion 34, so that the canister 16 can be attached and detached from the curved portion 34 by magnetic force. In this case, it is preferable that the inner diameter of the curved portion 34 and the outer diameter of the metal container 36 are approximately the same.

[0104] With this configuration, when the hydrogen stored in the canister 16 runs out, the canister 16 can be removed from the curved portion 24 and replaced with a new canister 16, or the canister 16 can be refilled with hydrogen and the refilled canister 16 can be inserted into the curved portion 24 and fixed in place by magnetic force.

[0105] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the curved portion 34 may be made of a magnetic material such as iron.

[0106] The canister 16 can be detachably attached to the facial cooling device 10 in a variety of ways, including using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or fitting the canister 16 into the curved portion 34 of the facial cooling device 10 and fixing with a spring.

[0107] FIG. 15 is a front view of a facial cooling device 62 according to another embodiment of the present disclosure in an unfolded state. The wearing belt 64 can have the same configuration as the wearing belt 14 of the embodiment shown in FIGS. 7 to 9. A slit-shaped opening 66 corresponding to the eye area is formed in the center of the wearing belt 64. Canisters 16a, 16b for cooling the target area are disposed on both sides of the opening 66. In this case, the canisters 16a, 16b are disposed with their axes aligned with the longitudinal direction of the wearing belt 64. In the facial cooling device 62, when the user presses the push button 54 of the nozzle portion 40 in the direction of the arrow, hydrogen gas is released from the canisters 16a, 16b, and the target area is cooled.

[0108] At this time, in order to fix the canisters 16a, 16b to the mounting belt 64, the openings of the curved portions 34 are arranged in a state that aligns with the longitudinal direction of the mounting belt 64. In this case, the curved portions 34 are formed in a generally cylindrical shape using the nylon layer 24, the urethane layer 26, etc., and the openings of the curved portions 34 formed in a generally cylindrical shape are fixed with an adhesive or the like so that they are positioned in the longitudinal direction of the mounting belt 64. Then, as in the first embodiment, the canisters 16a, 16b are fixed by being inserted into the openings of the curved portions 34.

[0109] Any method can be used to form and fix the curved portion 34, as long as the canister 16 can be inserted into the opening of the curved portion 34. Furthermore, as long as the canister 16 can be fixed to the mounting belt 64, the curved portion 34 does not have to be used, and the fixing direction of the canister 16 is not limited to the longitudinal direction of the mounting belt 64, but may be any direction, such as perpendicular or diagonal to the longitudinal direction of the mounting belt 64.

[0110] The canisters 16a, 16b may be fixed to the curved portion 34 with adhesive, screws, or brazing. As in the first embodiment, the canister 16 may be a metal container 36 having part or all of its side and / or bottom surfaces made of or attached to a magnetic material such as iron, or a magnet or the like attached to part or all of the inner wall surface of the curved portion 34, so that the canister 16 can be attached and detached from the curved portion 34 by magnetic force. In this case, it is preferable that the inner diameter of the curved portion 34 and the outer diameter of the metal container 36 are approximately the same.

[0111] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the curved portion 34 may be made of a magnetic material such as iron.

[0112] The canister 16 can be detachably attached to the facial cooling device 62 in a variety of ways, including using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or fixing the canister 16 by fitting it into the curved portion 34 of the facial cooling device 62 with a spring.

[0113] The target area of ​​the facial cooling device 10 described above is the eyes and / or the surrounding areas, but it can also be used on the arms, legs, fingers, etc. In such cases, the number of canisters can be changed to one or more as appropriate depending on the target area. The shape of the facial cooling device 10 can also be changed depending on the target area.

[0114] Therefore, in this case, facial cooling device 10 is used as a cooling device. That is, the cooling device is a cooling device for cooling a target area of ​​a user, and includes a wearing belt worn around the area of ​​the user where the target area is located, at least one canister filled with a hydrogen storage alloy that is fixed to the wearing belt and placed at the target area, a cooling plate that is fixed to the wearing belt and in contact with the canister, and a thermally conductive sheet that is fixed to the wearing belt and placed at the target area in contact with the cooling plate, and hydrogen gas is released from the canister to cool the cooling plate, and the target area is cooled via the thermally conductive sheet.

[0115] Fig. 16 is an explanatory diagram of a glove-type cooling device 68 according to yet another embodiment of the present disclosure worn on a hand 70. Fig. 17 is a plan view of the glove-type cooling device 68 from the back of the hand 70, Fig. 18 is a side view of the nozzle portion 40 side of the canister 16 worn on the glove-type cooling device 68, Fig. 19 is another side view of the glove-type cooling device 68, Fig. 20 is a view (bottom view) of the glove-type cooling device 68 from the palm side, and Fig. 21 is a perspective view of the glove-type cooling device 68.

[0116] In the glove-type cooling device 68, the canister 16 is attached to the inside or outside of a glove 72, which is an attachment worn on a hand 70. Figures 17 to 21 show the case where the canister 16 is attached to the inside of the glove 72. The canister 16 is arranged so as to fit along the back of the hand (fist), which is part of the hand 70. The nozzle portion 40 is exposed to the outside of the glove 72.

[0117] The canister 16 of the glove-type cooling device 68 can have various shapes, as in the above-described embodiments. However, the outer shape of the metal container 36 of the canister 16 in this embodiment may be a generally rectangular prism with one concave side that fits the back of the hand 70. An example of this is shown in FIG. 22 . A thermally conductive sheet 22, preferably made of silicone rubber or the like containing a thermally conductive filler, may be attached to the concave side 73 of the canister 16. An antibacterial film 46 may also be attached to the surface of the thermally conductive sheet 22. In this embodiment, the cooling plate 20, nylon layer 24, and urethane layer 26 may not be provided.

[0118] When a hand 70 is placed on the glove 72, the canister 16 is attached to the glove 72 at the position on the inner surface of the glove 72 that comes into contact with the back of the hand, so that the surface opposite the concave side 73 of the canister 16 faces outward from the glove 72, thereby forming a glove-type cooling device 68 (see Figure 20).

[0119] The canister 16 attached to the glove-type cooling device 68 is attached so that the surface opposite to the concave side surface 73 of the canister 16 is located on the inner surface of the glove 72 that comes into contact with the back of the hand 70, so that when the glove 72 is worn on the hand 70, the concave side surface 73 of the canister 16 is positioned so as to come into contact with the back of the hand 70 via the thermally conductive sheet 22 and the antibacterial film 46.

[0120] Therefore, when the user puts the glove-type cooling device 68 on the hand 70 and then presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, hydrogen gas is released from the canister 16, and the back of the hand 70 is cooled.

[0121] Alternatively, the canister 16 may be attached to the outside of the glove 72 by cutting out a portion of the surface of the back of the hand of the glove 72 and attaching the canister 16 so that the concave side surface 73 of the canister 16 is positioned there.

[0122] The canister 16 attached to the glove-type cooling device 68 may be detachably attached to the glove 72. For example, the canister 16 may be inserted into a bag provided in the glove 72, making the canister 16 detachable. A hole may be provided in a part of the bag, and the nozzle portion 40 of the canister 16 may be inserted therethrough, exposing the nozzle portion 40 to the outside from the glove 72.

[0123] The bag of the glove 72 is preferably provided on the surface of the glove 72 that comes into contact with the back of the hand 70, and one surface of the bag, particularly the surface that comes into contact with the back of the hand 70, is preferably open, with the concave side surface 73 of the canister 16 exposed from the open portion. Therefore, the concave side surface 73 of the canister 16 inserted into the bag of the glove 72 comes into contact with the back of the hand 70, and the temperature of the concave side surface 73 drops, thereby cooling the back of the hand 70.

[0124] The canister 16 may be fixed to the grab 72 with an adhesive. Alternatively, the canister 16 may be formed of or have a magnetic material such as iron attached to part or all of the side and / or bottom of the metal container 36, or a magnet or the like may be attached to part or all of the inner wall surface of the grab 72, so that the canister 16 can be attached and detached from the grab 72 by magnetic force.

[0125] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the grab 72 may be made of a magnetic material such as iron.

[0126] The canister 16 can be detachably attached to the grab-type cooling device 68 in various ways, such as by using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or by fitting the canister 16 into the grab 72 of the grab-type cooling device 68 and fixing with a spring.

[0127] As a modification of the glove-type cooling device 68, a cooling plate 20 may be attached to one side of the canister 16. An example of a canister 16 in this case is shown in Figure 23. In this case, the canister 16 does not need to be provided with the concave-shaped side surface 73 as in Example 3. Figure 23 shows a case where the cooling plate 20 is attached so that its longitudinal direction is parallel to that of the canister 16, but the cooling plate 20 may also be attached so that its longitudinal direction is not parallel to that of the canister 16, for example, so that its longitudinal direction is perpendicular to that of the canister 16.

[0128] As in the third embodiment, the canister 16 with the cooling plate 20 attached is attached to the inside or outside of the glove 72. The cooling plate 20 is then folded into a ring shape along the inner surface of the glove 72, facing away from the canister 16. As a result, when the temperature of the canister 16 drops due to the release of hydrogen gas, the temperature of the cooling plate 20 also drops. The temperature of the entire surface of the hand 70 wearing the glove 72 is then lowered via the cooling plate 20. An antibacterial film 46 may also be attached to the surface of the cooling plate 20.

[0129] In addition to the cooling plate 20, a thermally conductive sheet 22 formed in a ring shape may be used, and an antibacterial film 46 may be attached to the surface of the thermally conductive sheet 22.

[0130] An example of a glove-type cooling device 68 in this embodiment is shown in Figures 24 to 26. Figure 24 is a plan view of the glove-type cooling device 68 from the back side of the hand 70, Figure 25 is a view (bottom view) of the glove-type cooling device 68 from the palm side, and Figure 26 is a perspective view of the glove-type cooling device 68.

[0131] Alternatively, the canister 16 may be attached to the outside of the glove 72 by cutting out a portion of the surface of the back of the hand of the glove 72 and attaching the canister 16 so that the concave side surface 73 of the canister 16 is positioned there.

[0132] The canister 16 attached to the glove-type cooling device 68 may be detachably attached to the glove 72. For example, the canister 16 may be inserted into a bag provided in the glove 72, making the canister 16 detachable. A hole may be provided in a part of the bag, and the nozzle portion 40 of the canister 16 may be inserted therethrough, exposing the nozzle portion 40 to the outside from the glove 72.

[0133] The bag of the glove 72 is preferably provided on the surface of the glove 72 that comes into contact with the back of the hand 70, and one surface of the bag, particularly the surface that comes into contact with the back of the hand 70, is open, with the cooling plate 20 exposed from the open portion. The cooling plate 20 is attached in a ring shape inside the glove 72. Therefore, the cooling plate 20 of the canister 16 inserted into the bag of the glove 72 comes into contact with the back or palm of the hand 70, and the temperature of the cooling plate 20 drops, thereby cooling the back or palm of the hand 70.

[0134] The canister 16 may be fixed to the grab 72 with an adhesive. Alternatively, the canister 16 may be formed of or have a magnetic material such as iron attached to part or all of the side and / or bottom of the metal container 36, or a magnet or the like may be attached to part or all of the inner wall surface of the grab 72, so that the canister 16 can be attached and detached from the grab 72 by magnetic force.

[0135] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the grab 72 may be made of a magnetic material such as iron.

[0136] The canister 16 can be detachably attached to the grab-type cooling device 68 in various ways, such as by using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or by fitting the canister 16 into the grab 72 of the grab-type cooling device 68 and fixing with a spring.

[0137] As in Example 3, when the user puts the glove-type cooling device 68 on the hand 70 and then presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, hydrogen gas is released from the canister 16, cooling the back of the hand 70.

[0138] FIG. 27 is an explanatory diagram of a finger-shaped cooling device 74 according to yet another embodiment of the present disclosure attached to a finger 76. The finger-shaped cooling device 74 includes an attachment 78 and a holding attachment 80. The attachment 78 has a through-hole through which the finger 76 is inserted. A canister 16 is disposed inside the attachment 78 so as to fit along the finger 76. The holding attachment 80 extends from the attachment 78 and is a support for holding the attachment 78. For example, as shown in FIG. 27 , the index finger is inserted into the attachment 78 as the finger 76, and the end of the holding attachment 80 is wrapped around the little finger. The finger-shaped cooling device 74 not only cools the finger 76 with the canister 16, but also serves as a splint.

[0139] As in the third and fourth embodiments, the cooling plate 20 is attached to one side of the canister 16 and is folded into a ring shape on the side opposite the canister 16. This allows the cooling effect of the canister 16 to be transmitted to the entire surface of the finger 76 wearing the brace 78 via the cooling plate 20. An antibacterial film 46 may also be attached to the surface of the cooling plate 20.

[0140] In addition to the cooling plate 20, a thermally conductive sheet 22 formed in a ring shape may be used, and an antibacterial film 46 may be further attached to the surface of the thermally conductive sheet 22.

[0141] The finger-shaped cooling device 74 in this embodiment preferably has a cylindrical canister 16 so as to fit the size of a finger.

[0142] The nozzle portion 40 is exposed to the outside from the equipment 78, and when the user presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, hydrogen gas is released from the canister 16 and the finger 76 is cooled.

[0143] An example of the finger-shaped cooling device 74 in this embodiment is shown in Figures 28 to 31. Figure 28 is a plan view of the finger-shaped cooling device 74, Figure 29 is a side view of the finger-shaped cooling device 74, Figure 30 is a bottom view of the finger-shaped cooling device 74, and Figure 31 is a perspective view of the finger-shaped cooling device 74.

[0144] The canister 16 may be fixed to the fitting 78 by forming an annular portion on the fitting 78 with an adhesive. The inner diameter of this annular portion may be approximately the same as the outer diameter of the canister 16. Alternatively, the canister 16 may be formed by forming part or all of the side and / or bottom surfaces of the metal container 36 from or attaching a magnetic material such as iron, or by attaching a magnet or the like to part or all of the inner wall surface of the annular portion of the fitting 78, so that the canister 16 can be attached to and detached from the fitting 78 by magnetic force.

[0145] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the annular portion of the fitting 78 may be made of a magnetic material such as iron.

[0146] The canister 16 can be detachably attached to the finger-shaped cooling device 74 in various ways, such as by using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or by fitting the canister 16 into the attachment 78 of the finger-shaped cooling device 74 and fixing with a spring.

[0147] After putting on the finger-shaped cooling device 74, the user presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, which causes hydrogen gas to be released from the canister 16, cooling the finger.

[0148] Another embodiment of the cooling device using the canister 16 of this embodiment is a cooling device 82 that cools by wrapping a holding device 86 (described later) around an arm, leg, or the like. An example of the wrap-around cooling device 82 of this embodiment is shown in Figures 32 to 35. Figure 32 is a perspective view of the wrap-around cooling device 82. Figure 33 is a plan view of the wrap-around cooling device 82, Figure 34 is a rear view of the wrap-around cooling device 82, and Figure 35 is a bottom view of the wrap-around cooling device 82.

[0149] The wrap-around cooling device 82 includes an orthosis 84 and a holding orthosis 86. The orthosis 84 has a looped portion 87 for wrapping around an arm or leg, and one or more canisters 16 are arranged on the orthosis 84 in the short direction of the orthosis 84. The holding orthosis 86 extends from the orthosis 84 and is a support for holding the orthosis 84 at the target site to be cooled, such as an arm or a leg. For example, the orthosis 84 is attached to the arm or leg, and the holding orthosis 86 is wrapped around the arm or leg to secure the orthosis 84 to the arm or leg.

[0150] When the canister 16 is attached to the equipment 84, it may be configured in the same manner as in the first embodiment. The equipment 84 is provided with a cooling plate 20 and is bent to a size that allows it to be wrapped around an arm or leg. A ring-shaped portion 87 is formed on the equipment 84 at the position where the canister 16 is attached. For example, the ring-shaped portion 87 is curved in a bag shape. In Figure 32, two ring-shaped portions 87 are formed. The cooling plate 20 is provided between the two ring-shaped portions 87.

[0151] One side of the canister 16 is fixed to the cooling plate 20. One or more canisters 16 can be fixed to the cooling plate 20. A thermally conductive sheet 22 is attached to the surface of the cooling plate 20 of the brace 84 facing the arm or leg, along the curved surface. An antibacterial film may also be attached to the surface of the thermally conductive sheet 22. This allows the cooling effect of the canister 16 to be transmitted to the arm or leg wearing the brace 84 via the cooling plate 20. An antibacterial film 46 may also be attached to the surface of the cooling plate 20.

[0152] The cooling plate 20 of the brace 84 may be provided on the outside with a nylon layer 24, a urethane layer 26, or the like. The holding brace 86 may be made of any material that can be wrapped around the arm or leg. The holding brace 86 can be fixed to the brace 84 by various fixing methods such as hook-and-loop fasteners or buttons.

[0153] The nozzle portion 40 is exposed to the outside from the annular portion 87 of the brace 84, and when the user presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, hydrogen gas is released from the canister 16, cooling the arms and legs.

[0154] The canister 16 attached to the wrap-type cooling device 82 may be attached so as to be freely detachable from the annular portion 87 of the wrap-type cooling device 82. For example, the canister 16 may be inserted into the annular portion 87 provided on the wrap-type cooling device 82, making the canister 16 detachable.

[0155] The canister 16 may be fixed to the annular portion 87 with an adhesive. Alternatively, the canister 16 may be formed of or have a magnetic material such as iron attached to part or all of the side and / or bottom surfaces of the metal container 36, or a magnet or the like may be attached to part or all of the inner wall surface of the annular portion 87, so that the canister 16 can be attached to and detached from the wrap-around cooling device 82 by magnetic force.

[0156] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the annular portion 87 may be made of a magnetic material such as iron.

[0157] The canister 16 can be detachably attached to the wrap-type cooling device 82 in various ways, such as by using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or by fitting the canister 16 into the attachment 84 of the wrap-type cooling device 82 and fixing with a spring.

[0158] After putting on the wrap-around cooling device 82, the user presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, which releases hydrogen gas from the canister 16 and cools the target area such as the arms or legs.

[0159] Another embodiment of the cooling tool using the canister 16 of the present disclosure shows a grip-type cooling tool 88 for cooling the canister 16 by gripping it in a target location such as the palm of your hand. An example of the grip-type cooling tool 88 in this embodiment is shown in Figures 36 to 38. Figure 36 is a front view of the grip-type cooling tool 88, Figure 37 is a side view of the grip-type cooling tool 88, and Figure 38 is a view showing the grip-type cooling tool 88 in use.

[0160] The grip-type cooling device 88 includes the canister 16 , a gripping device 89 and a fixture 90 .

[0161] The canister 16 has the same configuration as in the above-described embodiments, and includes a metal container 36 and a nozzle portion 40. The gripping device 89 is a device for holding the canister 16 at a target location such as the hand. The gripping device 89 is made of a flexible member such as a belt, and the metal container 36 and the gripping device 89 form a ring-shaped portion. By passing the hand through this ring-shaped portion, the user can grasp the canister 16 and hold the gripping device 89 at the target location to be cooled.

[0162] The fixing device 90 is a member for fixing the gripping device 89 to the canister 16. The fixing device 90 is provided near the lower end and near the upper end of the metal container 36, and fixes the gripping device 89 to the canister 16. The fixing device 90 provided on the upper end side may be provided on the nozzle portion 40 in addition to the metal container 36. The fixing device 90 can be fixed to the canister 16 by, for example, providing a hole in the metal container 36 or the nozzle portion 40 for inserting the gripping device 89, and inserting the gripping device 89 into the hole.

[0163] After grasping the handheld cooling device 88, the user presses the push button 54 at the end of the nozzle portion 40 in the direction of the arrow, which releases hydrogen gas from the canister 16 and cools the target area, such as the palm. In particular, the palms and soles of the feet contain blood vessels called arteriovenous anastomoses (AVAs), which connect arteries and veins. Cooling these AVA blood vessels helps prevent heatstroke, and using the handheld cooling device 88 of the present disclosure can help prevent heatstroke.

[0164] Another embodiment of the cooling device in this example is a contact-type cooling device 91 for cooling the eyelids, areas under the eyes, etc. An example of the contact-type cooling device 91 in this example is shown in Figs. 39 to 43. Fig. 39 is a perspective view of the contact-type cooling device 91. Fig. 40 is a front view of the contact-type cooling device 91, Fig. 41 is a side view of the contact-type cooling device 91, and Fig. 42 is a plan view of the contact-type cooling device 91. Fig. 43 is a bottom view of the contact-type cooling device 91.

[0165] The contact-type cooling device 91 includes a main body 92 and a support part 93. The main body 92 has a hollow cavity 96 formed therein, and an opening 95 is provided at the bottom end thereof, to which the nozzle part 40 of the canister 16 is attached.

[0166] The inner diameter of the hollow portion 96 of the main body 92 is formed to be approximately the same as the outer diameter of the canister 16, so that the canister 16 can be inserted into the hollow portion 96. In this case, the inner diameter of the opening 95 is approximately the same as the outer diameter of the canister 16. The nozzle portion 40 of the canister 16 is exposed from the opening of the main body 92.

[0167] A part or all of the surface of the cavity of the main body 92 is formed of a material with high thermal conductivity (thermal conductive portion 97), such as aluminum, gold, silver, copper, or graphene, and functions as the cooling plate 20. A part or all of the surface of the cavity is in contact with a part of the side and / or bottom surface of the canister 16, and cooling by the canister 16 is transmitted to the cavity surface of the main body 92.

[0168] One or more support portions 93 protrude from the upper surface of the main body portion 92. The support portions 93 protrude in the same direction as the longitudinal direction of the main body portion 92. One end of the support portion 93 is joined to the main body portion 92, and may be formed integrally with the main body portion 92.

[0169] The other end of the support portion 93 is joined to and supported by the contact portion 94. The contact portion 94 is formed approximately parallel to a horizontal plane and can be brought into contact with a target area such as the eyelid. The support portion 93 is joined to a thermally conductive portion 97, and the temperature drop caused by the release of hydrogen gas is transmitted to the support portion 93 and the contact portion 94 via the thermally conductive portion 97, thereby cooling the contact portion 94. The contact portion 94 is formed from a highly thermally conductive material such as aluminum, gold, silver, copper, or graphene. The contact portion 94 may have any shape, such as a substantially rectangular or elliptical shape, or may have any shape, such as a curved surface that conforms to the shape of the eyelid or under the eye.

[0170] The support portion 93 is connected to the heat conducting portion 97, and a decrease in the temperature of the canister 16 is transmitted to the support portion 93 and the contact portion 94 via the heat conducting portion 97, thereby cooling the contact portion 94.

[0171] It should be noted that the member that connects to the heat conductive portion 97 may not be the support portion 93 but may be a member that forms the abutting portion 94. In this case, the abutting portion 94 is a member such as a U-shaped member, a T-shaped member, or a J-shaped member that connects to the heat conductive portion 97 inside the main body portion 92 and is formed so that a decrease in temperature of the canister 16 is transmitted to each abutting portion 94. The support portion 93 may also function as a member that covers the main body portion 92 side of the abutting portion 94 and prevents the abutting portion 94 from increasing in temperature due to contact with the outside air.

[0172] When the user presses the push button 54 at the end of the nozzle portion 40, the check valve 50 opens, and the hydrogen stored in the hydrogen storage alloy of the metal container 36 of the canister 16 turns into gas and is released from the nozzle 56. This causes the temperature of the side and / or bottom of the canister 16 to drop, and this temperature drop is transferred to the surface of the cavity 96 (thermal conductive portion 97). The temperature drop of the thermal conductive portion 97 is then transferred to the support portion 93 and the contact portion 94, causing the temperature of the contact portion 94 to drop. Therefore, by holding the main body portion 92 and contacting the contact portion 94 against an eyelid or the like, the user can cool the eyelid, under the eye, or the like. Note that the target area may be other than the eyelid or under the eye.

[0173] In this case, the canister 16 may be formed of or have attached to a magnetic material such as iron on part or all of the side and / or bottom surfaces of the metal container 36. A magnet or the like may be attached to part or all of the surface of the hollow portion of the main body 92, so that the canister 16 can be attached and detached from the hollow portion by magnetic force.

[0174] Alternatively, a magnet may be attached to the canister 16, and part or all of the inner wall surface of the annular portion 87 may be made of a magnetic material such as iron.

[0175] Alternatively, the canister 16 may be fixed to the annular portion 87 with an adhesive.

[0176] The canister 16 can be detachably attached to the main body 92 in various ways, such as by using magnetic force as described above, adhesive force using tape or the like, fixing with a belt or the like, or fixing by fitting the canister 16 into the main body 92.

[0177] With this configuration, when the hydrogen stored in the canister 16 runs out, the canister 16 can be removed from the main body 92 and replaced with a new canister 16, or the canister 16 can be refilled with hydrogen and the refilled canister 16 can be inserted into the main body 92 and secured in place by magnetic force.

[0178] The canister 16 may be attached and detached from the main body 92 by any other means than the magnetic force as described above.

[0179] As another embodiment of the contact type cooling device 91 in this embodiment, the canister 16 may not be detachably attached to the main body 92, but the main body 92 may function as the canister 16. Figure 44 is a partial vertical cross-sectional view of the contact type cooling device 91 in this case.

[0180] The hollow portion 96 is provided with one or more rod-shaped or plate-shaped members made of aluminum, gold, silver, copper, graphene, or the like as heat conduction portions 97, which penetrate the end of the main body 92 opposite the opening 95 and are joined to the support portion 93 or the abutment portion 94. The hollow portion 96 is filled with a hydrogen storage alloy. Note that a heat lane or a heat pipe may be provided as the heat conduction portion 97 and used for cooling.

[0181] With the above-described configuration, when the user presses down the push button 54 attached to the nozzle portion 40, the check valve 50 opens, and the hydrogen stored in the hydrogen storage alloy in the hollow portion 96 of the main body portion 92 turns into gas and is released to the outside through the nozzle 56. The release of hydrogen gas lowers the temperature of the hollow portion 96 of the main body portion 92, and this temperature drop is transmitted to the support portion 93 and the contact portion 94 via the heat conduction portion 97. The contact portion 94 is the portion that is pressed against the eyelid or the like, and by pressing the contact portion 94 against the eyelid or the like, the temperature drop of the main body portion 92 is transmitted to the eyelid or the like, thereby cooling the eyelid or the like.

[0182] As another embodiment of the cooling device in this example, the canister 16 may be provided in clothing such as a vest. An example of an embodiment in which the canister 16 is provided in a vest 300 is shown in Figs. 57 and 58. Fig. 57 shows a front view of the vest 300 as clothing. Fig. 58 shows a side view of the vest 300. The fabric 301 of the vest 300 is preferably made of a breathable material, such as a mesh fabric used in bibs. Thermally conductive members 302, for example, sheets made of highly thermally conductive graphene (graphene sheets), are attached to appropriate locations on the surface (lining) of the fabric 301 of the vest 300 that comes into contact with the body, such as the front, back, neck area, and armpits.

[0183] A storage section 303 such as a pocket for storing the canister 16 is provided on the surface of the fabric 301 of the vest 300. The storage section 303 may have any configuration as long as it is capable of storing the canister 16. It is preferable that the vest 300 is provided with at least one canister 16. It is also preferable that the canister 16 is stored in a position corresponding to the thermally conductive member 302. The canister 16 can transfer heat to the thermally conductive member 302 via the fabric 301 or directly.

[0184] When a user uses the vest 300, the user puts on the vest 300 and then stores the canister 16 in the storage section 303. When the user presses down the push button 54 attached to the nozzle section 40, the check valve 50 opens, and the hydrogen stored in the hydrogen storage alloy in the metal container 36 turns into gas and is released to the outside from the nozzle of the nozzle section 40. The release of hydrogen gas lowers the temperature of the metal container 30. The drop in temperature is transferred to the heat conducting member 302 via the fabric 301 (preferably mesh fabric) of the vest 300 or directly. The heat conducting member 302 can then cool the user's body.

[0185] Although the case where the storage section 303 for storing the canister 16 is provided on the surface of the base material 301 has been described, it may also be attached to the back surface of the base material 301. Furthermore, both the storage section 303 for storing the canister 16 and the heat conductive member 302 may be provided on the surface of the base material 301.

[0186] The thermal conductive member 302 of the canister 16 may be any material with high thermal conductivity, such as a graphene sheet, or may be used as the cooling plate 20. When using the cooling plate 20, a thin copper plate, annealed copper plate, aluminum plate, or the like may be used to reduce weight. A composite material that combines copper plate or copper foil with high thermal conductivity may also be used. Furthermore, instead of a graphene sheet or cooling plate 20, a vest may be partially or entirely made using a highly thermally conductive thread. The target cooling area may be sewn with a highly thermally conductive thread. Examples of highly thermally conductive thread include threads made from hemp, rayon, cotton, silk, gold, silver, copper, and the like, as well as CNF (cellulose nanofiber) thread. When sewing a vest with a highly thermally conductive thread, the canister 16 is preferably in contact with the thread, so that the cooling effect of the side of the metal container 36 of the canister 16 is transmitted to the thread.

[0187] In addition to the vests mentioned above, the clothing may also include jackets, T-shirts, shirts, bibs, pants, training wear, etc. In addition to clothing, a shawl may also be used to cool the neck area. Clothing items also include clothing, shawls, and other accessories.

[0188] In the above-described embodiments, a cooling device for cooling a target part such as a human body is used as an example, but the cooling device can also be used as a cooling device for cooling a specific object other than a human. For example, the canister 16 may be used as a storage container for cooling, such as a cup. Of course, the canister 16 can also be used in a cooling device for cooling a specific object other than a cup.

[0189] Figures 45 and 46 show an example of a cup 200 using the canister 16. Figure 45 is a perspective view of the cup 200, and Figure 46 is a vertical cross-sectional view of the cup 200.

[0190] The container portion 201 of the cup 200 stores a liquid such as a beverage to be poured into the cup 200. Similar to the metal container 101 of the canister 16, the container portion 201 is preferably made of a material with high thermal conductivity, such as aluminum, gold, silver, copper, or graphene.

[0191] A hole 202 into which the canister 16 can be inserted is provided on the bottom surface of the container portion 201 of the cup 200. The hole 202 on the bottom surface side of the cup 200 is open. The inner diameter of the hole 202 is approximately the same as the outer diameter of the canister 16, so that the canister 16 can be inserted into the hole 202 with almost no gap. Furthermore, the depth of the hole 202 is greater than the height of the canister 16, so that the canister 16 does not protrude from the hole 202 even when the canister 16 is inserted into the hole 202.

[0192] The material of part or all of the side and / or bottom surface of the metal container 36 of the canister 16 may be formed from a magnetic material, and magnets may be provided on the side and / or bottom surface of the hole 202, so that the canister 16 is held in the hole 202 by magnetic force. Alternatively, magnets may be attached to part or all of the side and / or bottom surface of the metal container 36 of the canister 16, or the side and / or bottom surface of the hole 202 may be made of a magnetic material, so that the canister 16 is held in the hole 202 by magnetic force.

[0193] The hole 202 for inserting the canister 16 may be provided on the side surface of the container portion 201 instead of the bottom surface thereof. An example of a vertical cross section of the cup 200 in this case is shown in FIG.

[0194] When the push button 54 attached to the nozzle portion 40 of the canister 16 is pressed down while the canister 16 is inserted into the hole 202, the check valve 50 opens, and the hydrogen stored in the hydrogen storage alloy in the metal container 36 turns into gas and is released to the outside through the nozzle 56. At this time, the temperature of the metal container 36 drops rapidly due to the release of hydrogen gas. When the temperature of the metal container 36 drops, the temperature of the container portion 201 in contact with the metal container 36 drops. As a result, the temperature of the container portion 201 of the cup 200 is effectively cooled.

[0195] In the cup 200, the container part 201 of the cup 200 may be exposed to the outside, but in order to prevent it from being affected by external influences, the outside of the container part 201 may be provided with a structure that is resistant to the influence of heat. An example of the cup 200 in this case is shown in Figure 48.

[0196] The cup 200 of Fig. 48 is provided with a heat insulating section 203 on the outside of the container section 201. The heat insulating section 203 may have a vacuum inside to provide heat insulation, or may have a heat insulating material inside to provide heat insulation. The heat insulating section 203 is preferably formed in a cup shape so that the cup 200 can be stored therein. Note that Fig. 49 shows an example of the case where the canister 16 is inserted into the side of the container section 201 as in Fig. 47.

[0197] An annular member 208 made of a material with low thermal conductivity, such as rubber, is provided on the inner surface and / or bottom surface of the insulating portion 203. After the container portion 201 of the cup 200 is placed in the insulating portion 203, it comes into contact with the annular member 208 of the insulating portion 203, and the annular member 208 acts as a non-slip surface, preventing the container portion 201 from falling out of the insulating portion 203 when a user attempts to drink a beverage or the like using the cup 200 placed in the insulating portion 203. Therefore, it is preferable that the inner diameter of the annular member 208 is slightly smaller than the diameter of the container portion 201. In particular, when the container portion 201 has a tapered shape in which the diameter decreases from top to bottom, the outer diameter of the outer surface of the container portion 201 becomes larger than the inner diameter of the annular member 208 at some position on the side of the container portion 201, and the annular member 208 can support the container portion 201. This creates a gap between the heat insulating part 203 and the container part 201, making it difficult for the low temperature of the container part 201 to be transmitted to the heat insulating part 203, thereby suppressing a rise in temperature of the container part 201. There may also be a gap between the bottom surface of the heat insulating part 203 and the bottom surface of the container part 201.

[0198] The annular member 208 may be attached to the inner surface of the heat insulating portion 203 or to the outer surface of the container portion 201 .

[0199] Furthermore, in the case of cup 200 using heat insulating part 203, the upper edge of container part 201 of cup 200 may be trumpet-shaped so as to be positioned outside the upper end of heat insulating part 203. This makes it easier to remove container part 201 from heat insulating part 203 by hooking a finger on the trumpet-shaped upper edge when removing container part 201 from heat insulating part 203.

[0200] When placing the container part 201 of the cup 200 in the heat insulating part 203, it is preferable to release hydrogen gas to cool the container part 201 before placing the container part 201 in the heat insulating part 203. At this time, the release of hydrogen gas may be stopped or terminated, or may be continued. Hydrogen gas is light and moves to the top. Even when the container part 201 is placed in the heat insulating part 203, the risk is extremely low because hydrogen escapes into the atmosphere through a very small space.

[0201] Although the cup 200 described above is configured so that the canister 16 can be detachably attached, the canister 16 and the cup 200 may be integrated. An example of a vertical cross-sectional view of the cup 200 in this case is shown in Figure 50. Also, a bottom view of the cup 200 is shown in Figure 51.

[0202] In this case, a hole 202 and a hollow portion 204 are provided in a container portion 201 of a cup 200. The hole 202 and the hollow portion 204 form a flow path 205 through which hydrogen can flow. A nozzle portion 40 is provided in the hole 202 above the opening of the flow path 205. The inner diameter of the hole 202 may be large enough to allow the nozzle portion 40 to be installed, and the depth of the hole 202 is formed to be greater than the height of the nozzle portion 40.

[0203] A check valve 50 is connected to the other end of the flow path 205, and the tip of the check valve is connected to a filter 58 provided in the hollow portion 204. In addition, one or more rod-shaped or plate-shaped members made of aluminum, gold, silver, copper, graphene, or the like are provided in the hollow portion 204 as heat conduction members 207. A hydrogen storage alloy is built into the hollow portion 204. After the hydrogen storage alloy is built into or filled into the hollow portion 204, the hollow portion 204 is sealed with a lid 206.

[0204] When the push button 54 of the nozzle portion 40 is pressed down, the air in the flow path 205 etc. is compressed, opening the check valve 50, and the hydrogen absorbed in the hydrogen storage alloy filling the hollow portion 204 becomes gas, passes through the filter 58, passes through the flow path 205, and is released to the outside from the nozzle 56. At this time, the cooling effect caused by the release of hydrogen gas is transmitted to the container portion 201 via the heat conduction portion 207, and the temperature of the container portion 201 drops. As a result, the temperature of the container portion 201 of the cup 200 is effectively cooled.

[0205] As in FIG. 48 , the nozzle portion 40 may be provided on the side surface of the container portion 201. An example of a longitudinal cross-sectional view of the cup 200 in this case is shown in FIGS. 52 to 54 . FIG. 52 shows a case where the hole portion 202 is provided on the side surface, and a flow path 205 is formed as appropriate. FIG. 53 shows a case where the nozzle portion 40, the check valve 50, the filter 58, etc. are provided on the opening side of the hole portion 202. In this case, the flow path 205 can be shortened. Furthermore, FIG. 54 shows a case where the flow path 205 is not provided, and the bottom surface of the hole portion 202 forms one surface of the hollow portion 204. Since there is no need to form the flow path 205, the configuration of the cup 200 can be simplified.

[0206] As in the case where the canister 16 is used, a heat insulating section 203 may be provided on the outside of the container section 201. An example of this case is shown in Figures 55 and 56. Figure 55 shows an example where a heat insulating section 203 is provided on the outside of the container section 201 of the cup 200 of the embodiment in Figure 51, and Figure 56 shows an example where a heat insulating section 203 is provided on the outside of the container section 201 of the cup 200 of the embodiment in Figure 54.

[0207] An annular member 208 made of a material with low thermal conductivity, such as rubber, is provided on the inner surface and / or bottom surface of the insulating portion 203. After the container portion 201 of the cup 200 is placed in the insulating portion 203, it comes into contact with the annular member 208 of the insulating portion 203, and the annular member 208 acts as a non-slip surface, preventing the container portion 201 from falling out of the insulating portion 203 when a user attempts to drink a beverage or the like using the cup 200 placed in the insulating portion 203. Therefore, it is preferable that the inner diameter of the annular member 208 is slightly smaller than the diameter of the container portion 201. In particular, when the container portion 201 has a tapered shape in which the diameter decreases from top to bottom, the outer diameter of the outer surface of the container portion 201 becomes larger than the inner diameter of the annular member 208 at some position on the side of the container portion 201, and the annular member 208 can support the container portion 201. This creates a gap between the heat insulating part 203 and the container part 201, making it difficult for the low temperature of the container part 201 to be transmitted to the heat insulating part 203, thereby suppressing a rise in temperature of the container part 201. There may also be a gap between the bottom surface of the heat insulating part 203 and the bottom surface of the container part 201.

[0208] The annular member 208 may be attached to the inner surface of the heat insulating portion 203 or to the outer surface of the container portion 201 .

[0209] Furthermore, in the case of cup 200 using heat insulating part 203, the upper edge of container part 201 of cup 200 may be trumpet-shaped so as to be positioned outside the upper end of heat insulating part 203. This makes it easier to remove container part 201 from heat insulating part 203 by hooking a finger on the trumpet-shaped upper edge when removing container part 201 from heat insulating part 203.

[0210] When placing the container part 201 of the cup 200 in the heat insulating part 203, it is preferable to release hydrogen gas to cool the container part 201 before placing the container part 201 in the heat insulating part 203. At this time, the release of hydrogen gas may be stopped or terminated, or may be continued. Hydrogen gas is light and moves to the top. Even when the container part 201 is placed in the heat insulating part 203, the risk is extremely low because hydrogen escapes into the atmosphere through a very small space.

[0211] In the tenth embodiment, the cup 200 has been described, but other than the cup 200, any container for cooling liquids, solids, etc. may be used.

[0212] In the above-described embodiments, a cooling device for cooling a target portion of a human body or the like has been used as an example. However, the cooling device can also be used as a cooling device for cooling a target portion of an object other than a human, such as an animal. It can also be used as a cooling device for cooling a target portion of an object other than a human or an animal. In this case, for example, a portion of the side and / or bottom of one or more canisters 16 is joined to the cooling plate 20. Then, the object can be cooled by applying the cooling plate 20 to the target portion of the object to be cooled.

[0213] Various cooling devices can be constructed using the canister 16 of the present disclosure, but it goes without saying that various configurations can be adopted without departing from the spirit of the present disclosure, and are not limited to the above-described embodiments.

[0214] For example, the number of canisters attached to each cooling device, the attachment positions, and the attachment methods can be any number, any attachment positions, and any attachment methods.

[0215] In the canister and cooling device using the canister of the present disclosure, hydrogen gas is released from the hydrogen storage alloy filled in the canister, the cooling plate is cooled, and the target area is effectively cooled via the thermally conductive sheet. The target area is also uniformly cooled for a predetermined period of time. Furthermore, the canister can be refilled with hydrogen and reused multiple times, eliminating waste and causing no adverse impact on the environment. Furthermore, the canister is equipped with a replaceable filter, which allows for easy replacement even if the filter deteriorates over time or becomes clogged.
