Description

[Technical Field]

[0001] The present invention relates to a cooling / heating device that is attached to an affected part of the human body to cool or heat the affected part. [Background technology]

[0002] In everyday life, at home, in factories, hospitals, etc., when living in a hot environment, working outdoors in summer, or when fever develops in affected areas of the body, a commonly used method is to apply cooling devices such as ice packs filled with ice blocks, cold water cloths soaked in cold water, and cooling patches made of a water-containing gel on the surface of a cloth base to the affected area. Furthermore, for symptoms such as lower back pain, stiff shoulders, muscle pain, cold hands and feet, and neuralgia, thermal methods for warming parts of the human body or affected areas, such as hot compresses containing stimulants such as chili pepper extract, hot packs filled with hot water, and disposable hand warmers filled with chemical heat-generating agents such as iron powder, are widely and commonly used. In addition, as a method of dealing with abnormal heat sensations in the head, such as fever, hot flashes, and flushing, a commonly used method is to place head cooling devices, such as ice packs filled with ice blocks, cold water cloths soaked in cold water, and cooling patches with a water-containing gel on the surface of a cloth base, on the forehead of the human body. In addition, various cooling hats with cooling elements inserted into pockets in the hat or helmet have been proposed as a way to cope with abnormal heat sensations in the head when going outside in summer or wearing a hat or helmet at a construction site. Cooling aids to be worn under the hat or helmet have also been proposed.

[0003] Furthermore, in medical settings, chemotherapy used in cancer treatment, etc., involves the administration of therapeutic drugs, which are absorbed by the hair roots through blood vessels near the hair roots, often resulting in hair loss, which causes significant psychological distress for patients. Regarding hair loss, it is known that hair loss can be prevented by maintaining a low scalp temperature to constrict blood vessels and inhibiting the absorption of therapeutic drugs by the hair roots. In response to this, an electric heat exchange type head cooling device has been proposed to prevent hair loss in patients undergoing chemotherapy.

[0004] The following devices have been disclosed as cooling or heating devices for cooling or heating affected areas of the human body. Japanese Patent Publication No. 2019-533 (Patent Document 1) discloses a body cooling device that can effectively cool any part of the body, particularly the neck, characterized in that it is configured in a bag shape with an inner mesh layer, an outer knit layer, and a rubber layer interposed between the mesh layer and the knit layer, and has a dry ice storage section that stores dry ice in the space surrounded by the mesh layer.

[0005] Japanese Patent Application Laid-Open Publication No. 2018-389 (Patent Document 2) discloses a heating / cooling device attachment device for attaching a heating or cooling device to the body, which has a cylindrical main body portion that is open at both axial ends so that the attachment part on the body can be inserted through it, the main body portion has a fixing portion where at least a part of the outer periphery protrudes outward, the main body portion is provided with a storage portion that can store and insert / remove the heating or cooling device, and at least one surface of the fixing portion is provided with a fixing means that can be engaged and detached with the outer periphery surface of the main body portion.

[0006] The following cooling devices have been disclosed as cooling devices for cooling the human head. Japanese Utility Model Application Laid-Open Publication No. 63-60426 (Patent Document 3) discloses a head cooling hat in which an insulating hat-shaped body is removably attached to the inside of a hat body made of a flexible material such as a cloth, along the hat body, and a cooling bag of appropriate thickness made by sealing a gel-like refrigerant in a bag formed of a synthetic resin film along the inner wall surface of the insulating hat-shaped body is removably fixed with a zipper, and a highly breathable, somewhat thick, hat-shaped cushion body is removably attached to the front side of the cooling bag.

[0007] As a cooling aid that can be worn inside a hat, Japanese Patent Application Laid-Open No. 2003-88543 (Patent Document 4) discloses a cooling aid member that is made by heat-sealing two sheets of material to form a bag shape and storing a required amount of highly water-absorbent polymer inside, and at least one of the two sheets is water-permeable, and the overall shape of the cooling aid member for hats is circular or polygonal, with multiple seals formed radiating from the center.This method of cooling the head when wearing a hat allows the cooling medium to be re-cooled and used repeatedly, and the cooling medium can be easily handled in a household refrigerator, etc., has good contact with the head, allows the head to be cooled with a single cooling medium, and has the effect of being usable without a dedicated helmet or hat, etc.

[0008] In particular, the following head cooling devices have been proposed for medical use. Japanese Patent Laid-Open Publication No. 11-269714 (Patent Document 5) discloses a hat comprising a hat body to be worn on the head and a cooling medium that partially cools the head, the hat body having a pocket-shaped cooling medium storage section in which the cooling medium is placed, the cooling medium storage section being provided in multiple places on the hat body and being selected and used appropriately according to the part of the head that is to be cooled, and the cooling medium being stored in any position, thereby preventing an increase in blood flow, controlling the expansion of blood vessels and soothing headaches, and also disclosing that by placing the medium in any part, the hat as a whole can be made lighter, which has the effect of reducing discomfort when worn by the user.

[0009] In particular, the following head cooling devices have been proposed as medically usable head cooling devices for preventing hair loss during chemotherapy treatment of cancer patients with anticancer drugs. JP 2013-533079 A (Patent Document 6) proposes "a body part temperature regulating device for regulating the temperature of a part of the body of a human or animal, comprising a controller, the controller being configured to receive inputs from temperature sensors configured to detect the temperature of a heat transfer fluid at first, second, and third positions of the heat transfer fluid, respectively, the controller being configured to determine the amount of heat to be transferred to the heat transfer fluid using the first, second, and third inputs, and to output a control signal based on the amount of heat, thereby regulating the amount of heat transferred to the heat transfer fluid." In particular, it discloses that the body part temperature regulating device can be worn on the head of a cancer patient during chemotherapy treatment in which an anti-cancer drug is administered to cool the scalp and suppress blood flow near the hair roots on the surface of the scalp, thereby having the effect of suppressing hair loss.

[0010] JP 2015-156965 A (Patent Document 7) discloses a head cooling device comprising: "a cooling cap to be worn on the head; a cooling medium flow path formed inside the cooling cap and extending between a first cooling medium port and a second cooling medium port; a cooler for cooling the cooling medium; a cooling medium flow direction reversing mechanism for selectively supplying the cooling medium cooled by the cooler to one of the first cooling medium port and the second cooling medium port and discharging the cooling medium that has flowed through the cooling medium flow path from the other of the first cooling medium port and the second cooling medium port; and a control device for controlling the operation of the cooling medium flow direction switching mechanism, wherein the control device can reverse the flow direction of the cooling medium flowing through the cooling medium flow path in the cooling cap by the cooling medium flow direction reversing mechanism." The device is particularly useful as a device for cooling the scalp and suppressing blood flow near the hair roots on the surface of the hair during chemotherapy treatment in which anticancer drugs are administered to a cancer patient, when worn on the head.

[0012] In the above-mentioned conventional technologies, the body cooling devices and thermal cooling device attachment devices disclosed in Patent Publication No. 2019-533 (Patent Document 1) and Patent Publication No. 2018-389 (Patent Document 2) tend to maintain the desired cooling temperature for a short period of time when attached to an affected part of the human body and cannot be used for long periods of time. The head cooling devices for cooling the human head disclosed in Japanese Utility Model Application Publication No. 63-60426 (Patent Document 3) and Japanese Patent Publication No. 2003-88543 (Patent Document 4), and the head cooling device for medical use disclosed in Japanese Patent Publication No. 11-269714 (Patent Document 5), when attached to an affected part of the human body, tend to maintain the desired cooling temperature for a short period of time and cannot be used for long periods of time. The head cooling devices disclosed in JP 2013-533079 A (Patent Document 6) and JP 2015-156965 A (Patent Document 7) are used for medical purposes to prevent hair loss in cancer patients during chemotherapy treatment involving the administration of anticancer drugs. However, because they require an electrical cooling mechanism to cool the cooling medium (or heat transfer fluid) that constitutes them, there is a problem in that the movement of the head and the behavior of the patient wearing the head cooling device are significantly restricted.

[0013] The present invention provides a cooling / heating device that includes a cooling / heating medium containing a cooling agent or a heating agent and can be easily attached to an affected part of the human body without requiring an electric cooling mechanism device or an electric heating mechanism device. When attached to an affected part of the human body, the cooling / heating medium prevents the cold air or warm air from escaping to the outside, effectively cooling or heating the affected part of the human body, thereby achieving the effect of maintaining a comfortable cooling temperature for a long period of time, or maintaining a comfortable warm temperature for a long period of time, and further providing the effect of maintaining a comfortable warm temperature for a long period of time, and further providing the effect of maintaining a comfortable warm temperature for a long period of time, and further providing the effect of maintaining a comfortable warm temperature for a long period of time, or To provide a cooling / heating device that can be worn on affected areas on the skin surface near essential blood vessels such as arteries and veins of the human body, such as arteries, groin, wrists, armpits, palms, and soles, to cool or heat the blood and suppress a rise or fall in body temperature, thereby efficiently cooling or heating the human body, and as a result, can be expected to have excellent "body temperature rise suppression effects when body temperature rises," such as suppressing body temperature rise when the human body has a fever and preventing heat stroke, or "heating effects and body temperature retention effects on affected body parts in cold environments," such as keeping affected body parts warm in severely cold environments and preventing frostbite.

[0014] In particular, the cooling and heating device is provided when the affected part of the human body is the human head, and is equipped with a cooling and heating medium containing a cooling or heating agent that can be easily attached to the human head without requiring an electric cooling mechanism or an electric heating mechanism. When attached to the human head, the cooling and heating device inhibits the external dispersion of cold or warm air caused by the cooling and heating medium containing the cooling or heating agent, thereby efficiently cooling or heating the human head and achieving the effect of maintaining a comfortable cooling temperature for a long period of time, or maintaining a comfortable warm temperature for a long period of time.Furthermore, when attached to the human head, the cooling and heating device can be efficiently cooled or heated, resulting in an excellent "body temperature rise suppression effect when body temperature rises," such as suppressing body temperature rise when the human body develops a fever and preventing heatstroke, or a "warming effect and body temperature retention effect on the human head in a cold environment," such as keeping the affected part of the human body warm in a severely cold environment and preventing frostbite.

[0015] Furthermore, in particular, when the affected area of ​​the human body is the human head, we provide a cooling / heating device equipped with a cooling / heating medium containing a coolant that can be easily attached to the human head without the need for an electrical cooling mechanism device, and in applications as a medical head cooling device in which the cooling / heating medium is the cooling medium, we provide a cooling / heating device that efficiently cools the surface of the human head and scalp with cold air from the cooling medium, has excellent cooling performance for cooling the head such as having a ``long-term duration of comfortable cooling temperature,'' prevents the cooling medium from falling off the human head, and has a ``comfortable fit and a sense of freedom of movement,'' such as allowing the wearer to move freely without being restricted by the attachment of an electrical cooling mechanism device. Furthermore, in anti-cancer drug treatment, it is generally known that cooling the scalp surface where hair grows and / or the scalp has a hair loss inhibiting effect, inhibiting hair loss caused by anti-cancer drugs administered to cancer patients in chemotherapy. Therefore, when used on a patient who has been administered an anti-cancer drug, it is possible to efficiently cool the entire scalp surface where hair grows and / or the scalp, thereby constricting blood vessels near the hair follicles and / or hair roots, reducing blood flow and reducing the amount of anti-cancer drugs administered to cancer patients in chemotherapy that flow near the hair follicles and / or hair roots, thereby providing a cooling / heating device that can be expected to have a "hair loss inhibiting effect" that inhibits hair loss caused by anti-cancer drugs.

BEST MODE FOR CARRYING OUT THE INVENTION

[0026] <Basic configuration of cooling and heating equipment 1> FIG. 1 is a schematic diagram illustrating the configuration of a cooling / heating device according to one embodiment of the present invention. FIG. 1 is a schematic cross-sectional view showing the cross-sectional structure of the cooling / heating device. Fig. 1(A) is a cross-sectional view of the surface member 2. Fig. 1(B) is a cross-sectional view showing the configuration of the cooling / heating medium 3 installed on the inner surface side of the surface member 2, and Fig. 1(Ba) is a cross-sectional view of the cooling / heating medium 3.

[0027] As shown in Figure 1(B), the cooling / heating device 1 of the present invention is a cooling / heating device for cooling or heating an affected part of the human body, and comprises a surface member 2 and a cooling / heating medium 3 placed on the inner surface side of the surface member 2. The surface member 2 is at least made of a porous foamed plastic material 20, and the foamed plastic material 20 is a closed-cell foamed plastic material having porous closed cells and / or an open-cell foamed plastic material having porous open cells. When the cooling / heating device is worn to cover the surface of an affected part of the human body, the cooling / heating medium 3 is positioned between the surface member 2 and the affected part of the human body, and is configured to be able to cool or heat the affected part of the human body.

[0028] This configuration provides the following effects: [Configuration Effect 1: A cooling / heating device equipped with a cooling / heating medium containing a cooling agent or a heating agent that can be easily attached to an affected part of the human body without requiring an electric cooling mechanism device or an electric heating mechanism device, and when attached to an affected part of the human body, the external dispersion of cold air or warm air caused by the cooling / heating medium is suppressed, and the affected part of the human body is efficiently cooled or heated, maintaining a comfortable cooling temperature for a long time, i.e., "long-term comfortable cooling temperature duration," or maintaining a comfortable warming temperature for a long time, i.e., "long-term comfortable warming temperature duration," and further By attaching the device to the affected area on the skin surface near the main blood vessels such as arteries and veins of the human body, such as the carotid artery, groin, wrist, armpit, palm, sole of the foot, etc., the device cools or heats the blood to suppress a rise or fall in body temperature, making it possible to efficiently cool or heat the human body. As a result, a cooling / heating device can be obtained that can be expected to have excellent effects such as "suppressing body temperature rise when body temperature rises," such as suppressing body temperature rise when the human body develops a fever and preventing heat stroke, or "heating effect and body temperature retention effect on the affected part of the human body in a cold environment," such as keeping the affected part warm in a severely cold environment and preventing frostbite.

[0029] For example, in the cooling and heating device of the present invention, the cooling and heating device containing a cooling medium can provide the cooling and heating device that exhibits the above-mentioned "Constituent Effect 1" during hot summer months, outdoors in the blazing sun, when the human body has a fever due to illness, etc. Furthermore, in the cooling / heating device 1 of the present invention, the cooling / heating device containing the cooling medium can provide the cooling / heating device that exhibits the above-mentioned "Constituent Effect 1" while working or studying.

[0030] In the present invention, the surface member 2 is at least constituted by a foamed plastic material 20, and the foamed plastic material 20 is a closed-cell foamed plastic material having porous closed cells and / or an open-cell foamed plastic material having porous open cells. Generally, the thermal conductivity of ordinary plastic materials such as polyethylene, polystyrene, polyurethane, polyvinyl acetate, and silicone rubber is about 0.15 W / mK to about 0.35 W / mK, whereas the thermal conductivity of porous foamed plastic materials formed by foaming these plastics to form a porous material with numerous fine bubbles is about 0.025 W / mK to about 0.1 W / mK. In other words, foamed plastic materials have lower thermal conductivity and superior heat insulating performance than ordinary non-foamed plastic materials. For example, the thermal conductivity of porous foamed polystyrene is about 0.03 W / mK to about 0.1 W / mK, the thermal conductivity of porous foamed polyurethane is about 0.025 W / mK to about 0.1 W / mK, the thermal conductivity of porous foamed polyethylene is about 0.035 W / mK to about 0.1 W / mK, the thermal conductivity of porous foamed polyvinyl acetate is about 0.035 W / mK to about 0.1 W / mK, and the thermal conductivity of porous foamed silicone rubber is about 0.05 W / mK to about 0.1 W / mK.

[0031] In this way, porous foamed plastic material has the property of suppressing heat conduction in the front-to-back direction. Therefore, the surface member 2 made of foamed plastic material has the effect of trapping the cold or warm air from the cooling / heating medium 3 inside and suppressing the cold or warm air from escaping to the outside, resulting in the aforementioned cooling / heating device that efficiently cools or heats the affected part of the human body and maintains a comfortable cooling temperature for a long time, or maintains a comfortable warm temperature for a long time.

[0032] The porous foamed plastic material 20 is a porous foamed plastic material having an extremely fine microstructure with numerous foamed cells, for example, with a cell diameter of 1000 μm or less, preferably 500 μm or less, and more preferably 100 μm or less. As the cell diameter of each bubble in the foamed plastic material 20 increases, the mechanical strength tends to decrease, and foamed plastic materials in which the cell diameter of each bubble is 1000 μm or less are preferred.

[0033] The thickness of the porous foamed plastic material 20 having the foamed cells is preferably 0.5 to 15 mm, more preferably 1 to 10 mm, and even more preferably 1.5 to 8 mm. As the thickness of the foamed plastic material 20 decreases, the mechanical strength decreases and the ability to maintain a three-dimensional shape tends to decrease, so in this respect, a foamed plastic material having a thickness of 0.5 mm or more is preferred. Also, as the thickness of the foamed plastic material increases, the weight increases, and the surface member tends to feel heavy and uncomfortable when attached to the affected part of the human body, so in this respect, a foamed plastic material having a thickness of 15 mm or less is preferred for the foamed plastic material 20.

[0034] Furthermore, as the foamed plastic material 20, foamed plastic materials containing the above-mentioned polyethylene, polystyrene, polyurethane, polyvinyl acetate, silicone rubber, or copolymers thereof as the main component, as well as calcium carbonate powder, talc powder, mica powder, silica powder, pigments, colorants, lubricants, antioxidants, plasticizers, colorants, preservatives, antibacterial agents, foaming agents, and other additives are preferably used.

[0061] For example, the foam plastic container 20c has a shape that has a substantially trapezoidal cross section, as shown in FIGS. 2(A), 4(C), 6(A), and 7(Aa).

[0062] As the cooling / heating device of this configuration, for example, the cooling / heating device of one embodiment shown in Figures 2, 4, 6, and 7(Ca) can be implemented. Figures 2, 4, and 6 are schematic diagrams for explaining the configuration of the cooling / heating device of the present invention, and are schematic plan views showing the outline. As shown in Figures 2(A), 4(C), 6(Aa), and 7(Ca), In the cooling / heating device of the present invention, preferably (e) the foamed plastic material 20 has the form of a foamed plastic storage container 20c having a flat surface 20a, a storage container flat surface peripheral side wall 20b formed around the flat surface, and a foamed plastic storage container opening 20e. The foamed plastic storage container 20c has the flat surface peripheral side wall 20b formed at an angle widening from the flat surface 20a toward the foamed plastic storage container opening 20e. For example, the foamed plastic storage container 20c has a shape that is approximately trapezoidal in cross section. As shown in Figures 2(B), (C), (D) and 6, the cooling / heating medium 3 is placed in a foamed plastic container 21, and when the cooling / heating device is worn covering the surface of the affected part of the human body, the side of the foamed plastic container opening 20e of the foamed plastic container 21 covers the surface of the affected part of the human body, making it possible to cool or heat the affected part of the human body. Preferably, the cooling / heating medium 3 is placed in the foam plastic container 20c in a shape that roughly matches the inner shape of the foam plastic container 20c.

[0063] Furthermore, as the foamed plastic material 20 described above, "(f) having the form of a foamed plastic storage container 20c having a storage container shape with a storage container flat surface portion 20a, a storage container flat surface peripheral side wall portion 20b formed around the storage container flat surface portion, a storage container portion flange portion 20k formed on the periphery of the storage container flat surface peripheral side wall portion on the opening side, and a foamed plastic storage container opening 20e, wherein the foamed plastic storage container 20c has a storage container flat surface peripheral side wall portion 20b formed at an angle widening from the storage container flat surface portion 20a toward the foamed plastic storage container opening 20e," for example, a foamed plastic storage container 20c having a storage container flat surface portion 20a, a storage container flat surface peripheral side wall portion 20b, a storage container portion flange portion 20k, and a foamed plastic storage container opening 20e as shown in Figure 7 (Ea) can be implemented. Also, for example, although not shown, it is possible to implement a foamed plastic material 20 similar to the foamed plastic storage container 20c having the storage container flange portion 20k as shown in Figure 4(D) above, and having a "storage container flange portion 20k formed on the periphery of the opening side of the storage container flat surface peripheral side wall portion 20b of the storage container flat surface peripheral side wall portion" of the foamed plastic material 20 shown in Figure 4(C) or Figure 4(E). In addition, in FIG. 7(Ea), a configuration in which the shape-retaining container sealing cover 32e is not provided is also possible.

[0064] With this configuration, [Configuration Effect 4: The above-mentioned "Configuration Effect 1" can be expected, and further, "Furthermore, since the foamed plastic storage container 20c has a storage container flat surface peripheral side wall portion 20b formed at an angle that widens from the storage container flat surface portion 20a toward the foamed plastic storage container opening 20e, the area of ​​the cooling / heating device that comes into contact with the affected part of the human body is wide due to the wide area of ​​the foamed plastic storage container opening 20e of the foamed plastic storage container 20c as the surface member 2, and this makes it possible to efficiently cool or heat the affected part of the human body, and since the corner angles of the outer shape of the foamed plastic storage container opening 20e are wide, damage caused by the corners is suppressed, and a cooling / heating device that has the effect of providing an excellent wearing comfort is obtained.

[0065] In particular, by the configuration of "the foamed plastic material 20 has the form of a foamed plastic storage container 20c having the form of a storage container formed with (f) a storage container flange 20k formed on the periphery of the opening side of the storage container flat surface peripheral side wall" and a foamed plastic storage container opening 20e, and the foamed plastic storage container 20c has a storage container flat surface peripheral side wall 20b formed at an angle widening from the storage container flat surface 20a toward the foamed plastic storage container opening 20e," [Configuration Effect 4-F: The above-mentioned configuration effect 4 is obtained, and further, the effect of the storage container flange 20k being able to be stably attached without falling off the affected part of the human body when attached to the human body is further improved significantly, resulting in an excellent wearing comfort].

[0067] Preferably, in addition to the above-mentioned configurations (e) and (f), the foamed plastic material 20 has a shape-retaining property that allows it to maintain the shape of the container. This configuration provides [Configuration Effect 4-a: A cooling / heating device that has an effect similar to the above-mentioned Configuration Effect 2, and furthermore, the configuration in which the foamed plastic material 20 in the form of the foamed plastic storage container 20c "has the shape retention ability to maintain the shape of the storage container" suppresses deformation of the foamed plastic material 20 as a surface member during use, resulting in a cooling / heating device 1 that can always maintain a stable shape.

[0068] The angle at which the storage container flat surface peripheral side wall portion 20b, which is formed at an angle that widens from the storage container flat surface portion 20a toward the foam plastic storage container opening 20e, widens is not particularly limited, but for example, an angle exceeding 90 degrees is preferable, and an angle in the range of 91 degrees to 160 degrees is even more preferable, and an angle in the range of 95 degrees to 150 degrees is even more preferable. If the angle of expansion is less than 90 degrees, there is a tendency for the corners to cause injury when the device is attached to an affected area of ​​the human body, and there is also a tendency for the device to feel uncomfortable when worn due to the corners.

[0069] [Subordinate Structure 5] The cooling / heating devices of the aforementioned "Subordinate Configuration 2," "Subordinate Configuration 3," and "Subordinate Configuration 4" preferably have the following configuration. "The foam plastic storage container 20c has a molded form and is in the form of a shape-retaining foam plastic molded storage container 20c that has shape-retaining properties that enable it to maintain the shape of the storage container with an opening formed therein, and a cooling / heating medium 3 is placed inside the shape-retaining foam plastic molded storage container 20c. When the cooling / heating device is worn covering the surface of an affected part of the human body, the side of the foam plastic storage container opening 20e of the shape-retaining foam plastic molded storage container 20c covers the surface of the affected part of the human body, making it possible to cool or heat the affected part of the human body."

[0070] This configuration allows for the production of a cooling / heating device 1 that achieves [Configuration Effect 5: the aforementioned "Configuration Effect 1" can be expected, as well as the effect of suppressing deformation of the shape-retaining foamed plastic molded container 20c serving as the surface member during use, thereby allowing the container to maintain a stable shape at all times], and the effect of making it easy to wear by covering the desired affected area of ​​the human body, and further, the effect of "since the shape-retaining foamed plastic molded container 20c serving as the surface member 2 is molded using a molding jig such as a mold, a cooling / heating device having the desired shape can be easily obtained, mass production becomes possible, and it can be supplied at low cost."

[0071] 1, 2 and 4 are schematic diagrams illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention.

[0079] As shown in Figure 5 (Ac), the foamed plastic material 20 has the form of a multiple-connected foamed plastic storage container 20d formed by connecting multiple (e.g., five) foamed plastic storage containers 20c to each other, and each foamed plastic storage container 20c of the multiple-connected foamed plastic storage container 20d has the form of a storage container with an opening formed therein, and a cooling / heating medium 3 is placed in each foamed plastic storage container 20c, so that when worn covering the surface of an affected part of the human body, the side of the foamed plastic storage container opening 20e of each foamed plastic storage container 20c covers the surface of the affected part of the human body, allowing the affected part of the human body to be cooled or heated, and a cooling / heating device that is configured to be bendable can be implemented.

[0080] As shown in Figures 5(Ba), 5(Bb), 5(Ca), and 5(Cb), the foam plastic material 20 has the form of a multiple-connected foam plastic storage container 20d formed by connecting multiple (e.g., three) foam plastic storage containers 20c to each other, and each foam plastic storage container 20c of the multiple-connected foam plastic storage container 20d has the form of a storage container with an opening formed therein, and a cooling / heating medium 3 is placed in each foam plastic storage container 20c, so that when the foam plastic storage container 20c is worn covering the surface of an affected part of the human body, the side of the foam plastic storage container opening 20e of each foam plastic storage container 20c covers the surface of the affected part of the human body, allowing the affected part to be cooled or heated, and a cooling / heating device 1 having a form in which a sealed cooling / heating medium is placed in each foam plastic storage container 20c can be implemented.

[0081] 5, the cooling / heating medium 3 may be preferably a cooling / heating medium in which a cooling / heating agent 31 is placed in a foam plastic container 20c, or a sealed cooling / heating medium in which a cooling / heating agent 31 is contained in a sealed container 32. A detailed description of this cooling / heating medium 3 will be given later.

[0082] The configuration of the cooling / heating medium sealing cover member 4 shown in FIG. 5 will be described later. The cooling / heating device 1 can be configured without the cooling / heating medium sealing cover member 4 shown in Figure 5. It is also possible to preferably use a cooling / heating device that includes the cooling / heating medium sealing cover member 4 described below.

[0083] [Subordinate Structure 7] The cooling / heating devices according to the aforementioned "subordinate configuration 2" to "subordinate configuration 6" preferably have the following configurations. [When attached to the surface of the affected part of the human body, the opening-forming member portion that forms the opening of the foamed plastic storage container 20c is deformed to fit the shape of the surface of the affected part of the human body and is formed so that it can be in close contact with the surface of the affected part of the human body]. [The foamed plastic storage container 20c is characterized in that, at room temperature of approximately 25°C, (i) it can be bent at a 90-degree angle without breaking when force is applied to the foamed plastic storage container 20c, and has sufficient flexibility to return to its original angle when the force is released, and / or (ii) it can be stretched by approximately 3% or more when force is applied in a direction widening the periphery of the foamed plastic storage container opening 20e of the foamed plastic storage container 20c, and has sufficient elasticity to contract to its original length when the force is released, and / or (iii) when the foamed plastic storage container 20c is attached with force applied in the direction of the surface of the affected part of the human body while containing the cooling / heating medium 3, the opening-forming member portion that forms the opening of the foamed plastic storage container 20c is compressed to adhere closely to and / or come into contact with the surface of the affected part of the human body, and has sufficient elasticity to return to its original state when the force is released].

[0084] In the above configuration, the opening forming member that forms the opening of the foamed plastic storage container 20c is the peripheral edge of the foamed plastic storage container opening 20e of the storage container portion 20h with the recessed recess formed therein, or the storage container portion flange 20k, in a configuration in which the foamed plastic material 20 is the storage container portion 20h with the recessed recess formed therein. In a configuration in which the foamed plastic material 20 is the foamed plastic storage container 20c with the storage container flat surface portion 20a formed therein, the opening forming member is the storage container flat surface peripheral side wall portion 20b or the storage container portion flange 20k.

[0085] For example, in the configuration of (A), a configuration is possible in which the foamed plastic storage container 20c can be bent at a 90-degree angle in any direction along any part thereof without breaking when force is applied, and has flexibility to return to the original angle when the force is released. Also, a configuration is possible in which the foamed plastic storage container 20c can be bent at a 90-degree angle from approximately the center in a plan view toward the foamed plastic storage container opening 20e without breaking when force is applied, and has flexibility to return to the original angle when the force is released. In addition, in the configuration (c), the opening forming member portion that forms the opening of the foamed plastic storage container 20c corresponds to the storage container portion 20h having a recessed depression, the storage container portion flange portion 20k, or the storage container flat surface surrounding side wall portion 20b. Furthermore, in the above configuration (c), in the case where the cooling / heating medium 3 has a shape-retaining container sealing cover 32e, when the cooling / heating medium 3 is placed in the foamed plastic storage container 20c, a configuration in which the shape-retaining container sealing cover 32e is positioned on the inner side of the outer peripheral region of the storage container flat surface peripheral side wall portion 20b or the storage container part flange portion 20k, exposing the outer peripheral portion of the storage container flat surface peripheral side wall portion 20b or the storage container part flange portion 20k, is preferably implemented.

[0086] For example, in the case of a cooling / heating device in which the circumferential length of the opening 20e of the foamed plastic storage container is approximately 23 cm, it is preferable that when force is applied in the circumferential direction, the device can be extended to a length of approximately 7 mm or more in the circumferential direction of the opening 20e of the foamed plastic storage container, and can be contracted to its original length when the force is removed.

[0087] As the foamed plastic material 20 constituting the surface member 2 having the above-mentioned flexibility and / or stretchability, at least one foamed plastic material 20 selected from the group consisting of foamed polyolefin resin, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer copolymerized with ethylene monomer and other vinyl monomer, foamed polyvinyl acetate, foamed natural rubber, foamed nitrile rubber, foamed nitrile-butadiene rubber, foamed chloroprene rubber, foamed silicone rubber, foamed ethylene-propylene rubber, foamed polyvinyl chloride, foamed polyvinyl alcohol, foamed polypropylene, foamed polyurethane, foamed polyacrylic, foamed ethylene propylene diene rubber, and foamed ester-based elastomer, as will be described in the "subordinate configuration 29" below, can be preferably implemented. As the foamed plastic material 20 constituting the surface member 2 having flexibility and / or stretchability, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer copolymerized with ethylene monomer and other vinyl monomer, or foamed polyvinyl acetate are particularly preferred.

[0088] In addition, as the foamed plastic material 20, foamed plastic materials containing calcium carbonate powder, talc powder, mica powder, silica powder, pigments, dyes, lubricants, antioxidants, plasticizers, colorants, preservatives, antibacterial agents, foaming agents, and other additives in addition to these polymers are preferably usable.

[0089] This configuration provides the aforementioned "Configuration Effects 2 to 6," as well as [Configuration Effect 7: The foamed plastic storage container 20c is flexible enough to be bent at a 90-degree angle without breaking when force is applied at room temperature of approximately 25°C, and to return to its original angle when the force is removed. As a result, when attached to an affected part of the human body, the foamed plastic storage container 20c deforms to conform to the shape of the affected part, such as the curved shape of the affected part and the flexible shape of the human skin, and easily adheres to the skin of the affected part, improving adhesion to the affected part of the human body. This prevents cold or warm air from escaping in the outward direction of the surface member 3, significantly improving the effect of cooling or warming the affected part of the human body].

[0090] [Subordinate Structure 2-7] Preferably, in the cooling / heating devices of the above-mentioned sub-configurations 2 to 7, the foamed plastic material 20 has the form of a foamed plastic storage container 20c having a storage container configuration with a storage container portion 20h having a recessed depression formed therein, a foamed plastic storage container opening 20e, and a storage container flange portion 20k formed on the periphery of the opening side of the storage container portion 20h, and the foamed plastic storage container opening 20e.

For example, in each of the foamed plastic storage containers 20c shown in Figures 4(A), (B), (C), and (E), it is also possible to implement a foamed plastic storage container 20c that has a storage container flange 20k formed around the opening of the foamed plastic storage container 20c, or a storage container flange 20k formed around the storage container flat surface peripheral side wall portion 20b, similar to the storage container flange portion 20k shown in Figure 4(D).

[The cooling / heating device 1 further includes a cooling / heating medium sealing cover member 4, which is characterized in that it has a shape that covers and seals the foam plastic container opening 20e of the foam plastic container 20 that contains the cooling / heating medium 3].

[0093] A preferred embodiment is one in which the cooling / heating medium sealing cover member 4 is joined to the foam plastic container 20c and sealed. In addition, a configuration in which the cooling / heating medium sealing cover member 4 covers the foamed plastic storage container opening 20e of the foamed plastic storage container 20c that contains the cooling / heating medium 3 and seals the end face of the side wall portion 20b surrounding the flat surface of the storage container is preferably implemented. In addition, a preferred embodiment is one in which the cooling / heating medium sealing cover member 4 is attached to and removably sealed at the opening of the foamed plastic storage container 20c, and is configured to be able to store / remove the cooling / heating medium 3 installed in the foamed plastic storage container 20c.

[0094] This configuration provides [Configuration Effect 8: the aforementioned "Configuration Effect 1" can be expected, and the effect of suppressing the cooling / heating medium 3 from falling off].

[0095] Preferably, the cooling / heating medium sealing cover member 4 is made of plastic and includes a flexible plastic film having flexibility. This configuration achieves the aforementioned "Configuration Effect 8-i:" and when the cooling / heating device 1 is attached to the affected area of ​​the human body, the wearer does not feel any stiffness due to the cooling / heating medium sealing cover member 4, providing a comfortable fit and allowing the device to be worn for long periods of time.

In addition, a configuration in which the outer shape of the shape-retaining container 32c roughly matches the inner shape of the foamed plastic storage container 20c, and the cooling / heating medium 3 is placed inside the foamed plastic storage container 20c, is preferably implemented. Furthermore, in the configuration of "a cooling / heating medium 3 in which a cooling / heating agent 31 is contained in a sealed container 32," it is preferable to implement the configuration of "a cooling / heating medium 3 in which a cooling / heating agent 31 is filled in a sealed container 32." Furthermore, in the configuration in which "the cooling / heating medium 3 is placed in a foam plastic storage container 20c," a configuration in which "the cooling / heating medium 3 is stored in a foam plastic storage container 20c" can be preferably implemented.

[0116] The above configurations (A), (A-a), (A-b), and (A-c) provide [Configuration Effect 9-A: The aforementioned "Configuration Effect 1" can be expected, and the area of ​​contact with the affected part of the human body can be maximized, making it possible to efficiently cool or heat the affected part of the human body. Also, a cooling / heating device 1 can be obtained that has the effect of being usable by repeating the cycle of storing the cooled or heated sealed cooling / heating medium 3 in a foam plastic storage container 20c, applying it to the affected part of the human body, removing the sealed cooling / heating medium 3 from the foam plastic storage container 20c after a predetermined time has passed, and then cooling or heating the removed sealed cooling / heating medium 3.

Furthermore, the cooled or heated sealed cooling / heating medium 3 can be contained in the foam plastic container 20c, which is then applied to the affected part of the human body. After a predetermined time has passed, the sealed cooling / heating medium 3 can be removed from the foam plastic container 20c, and the removed sealed cooling / heating medium 3 can be cooled or heated. This cycle can be repeated, and the configuration with the shape-retaining container flange 32d makes it significantly easier to remove the sealed cooling / heating medium 3 from the foam plastic container 20c, resulting in a cooling / heating device 1 that is easier to handle.

[0118] As the shape-retaining container 32c, a shape-retaining container 32c having an outer shape that matches the inner shape of the surface member 2 shown in FIG. 4 is preferably feasible. For example, a shape-retaining container 32c having an outer shape roughly the same as the inner shape of a foamed plastic storage container 20c having an inner shape that is roughly hemispherical as shown in Figure 4(A) can be preferably used as the shape-retaining container 32c.

[0120] Schematic diagrams illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention are shown in Figures 1(D), 1(Da), 2(D), 2(Da), 2(E), and 2(Ea).

[0124] FIG. 7 is a schematic diagram illustrating the configuration of the cooling / heating device 1 according to one embodiment of the present invention. As shown in Figures 7(Aa) and 7(Ab), the foamed plastic material 20 has a flat surface portion 20a and a flat surface peripheral side wall portion 20b formed around the flat surface portion, and has the form of a foamed plastic storage container 20c having the form of a storage container with a foamed plastic storage container opening 20e, and a cooling / heating medium 3 is placed in the foamed plastic storage container 20c. When the cooling / heating device 1 is worn covering the surface of the affected part of the human body, the side of the foamed plastic container opening 20e of the foamed plastic container 20c covers the surface of the affected part of the human body, so that the affected part of the human body can be cooled or heated.

[0125] As shown in Figures 7(Ba) and 7(Bb), (i) the sealed container 32 comprises a shape-retaining container 32c having enough shape-retaining ability to maintain its shape, and a shape-retaining container sealing cover 32e formed to cover the opening of the shape-retaining container 32c and be able to seal. A cooling / heating agent 31 is contained in the sealed container 32. Alternatively, (ii) the sealed container 32 comprises a shape-retaining container 32c having enough shape retention to maintain its shape, a shape-retaining container flange 32d formed around the opening of the shape-retaining container 32c, and a shape-retaining container sealing cover 32e that covers the opening of the shape-retaining container 32c and is joined to the shape-retaining container flange 32d so as to be able to seal. The cooling / heating agent 31 is contained in the sealed container 32.

[0126] As shown in Figures 7(Ca) and 7(Cb), a cooling / heating medium 3 is placed in a foamed plastic container 20c having a flat surface 20a and a flat surface peripheral side wall 20b formed around the flat surface, and a foamed plastic container opening 20e. Here, the cooling / heating medium 3 has a cooling / heating agent 31 contained in a sealed container 32 having a shape-retaining container 32c having enough shape-retaining ability to maintain its shape and a shape-retaining container sealing cover 32e formed to cover the opening of the shape-retaining container 32c and be able to seal it.

[0127] As shown in Figures 7(Da) and 7(Db), a cooling / heating medium 3 is placed in each of a plurality of interconnected foam plastic storage containers 20c. Here, the cooling / heating medium 3 has a cooling / heating agent 31 stored in a sealed container 32 comprising a shape-retaining container 32c that has enough shape-retaining ability to maintain its shape and a shape-retaining container sealing cover 32e that is formed to cover the opening of the shape-retaining container 32c and be able to seal.

[0128] As shown in Figures 7(Ea) and 7(Eb), a cooling / heating medium 3 is placed in a foamed plastic storage container 20c having a flat surface 20a, a flat surface peripheral side wall 20b formed around the flat surface, a storage container flange 20k formed on the periphery of the opening side of the storage container flat surface peripheral side wall, and a foamed plastic storage container opening 20e. Here, the cooling / heating medium 3 has a cooling / heating agent 31 stored in a sealed container 32 having a shape-retaining container 32c having enough shape-retaining ability to maintain its shape and a shape-retaining container sealing cover 32e formed to cover the opening of the shape-retaining container 32c and be able to seal it.

[0129] In Figure 7, (Ab), (Bb), (Cb), (Db), and (Eb) in Figure 7 are foamed plastic storage containers 20c that have a "storage container flat surface peripheral side wall portion 20b formed around the storage container flat surface portion 20a," and (Aa), (Ba), (Ca), (Da), and (Ea) in Figure 7 are foamed plastic storage containers 20c that have a "storage container flat surface peripheral side wall portion (20b) formed at a widening angle."

[0130] The material for forming the shape-retaining container sealing cover 32e is not particularly limited, but examples thereof include conventional plastic films such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polyamide, polyvinylidene chloride, polyvinyl acetate, etc., paper, metal-deposited film, aluminum foil, and laminated films of two or more of these. With the shape-retaining container sealing cover 32e covering the opening of the foam plastic storage container 20c, the shape-retaining container sealing cover 32e is joined to the periphery of the end face of the storage container flat surface peripheral side wall portion 20b, thereby sealing it.

[0131] Particularly preferably, the material constituting the shape-retaining container sealing cover 32e is a metal-vapor-deposited film such as aluminum and / or a film having aluminum foil, or an aluminum-containing laminated film formed by laminating the above-mentioned conventional plastic film with a metal-vapor-deposited film such as aluminum and / or aluminum foil. By constructing an aluminum-containing laminated film as the shape-retaining container sealing cover 32e, the excellent thermal conductivity of aluminum makes it possible to efficiently transmit the cold or warm air from the cooling or heating medium 3 contained in the foamed plastic container 20c to the affected part of the human body, thereby obtaining a cooling or heating device that provides an excellent wearing comfort, cooling sensation, or warmth sensation when attached to the affected part of the human body.

[0132] [Subordinate Structure 10] The cooling / heating devices 1 of the aforementioned "subordinate configuration 2" to "subordinate configuration 8" preferably have the following configurations. The cooling / heating medium 3 is configured in the form of a flexible sealed cooling / heating medium in which a cooling / heating agent 31 is accommodated in a sealed container 32, and the flexible sealed cooling / heating medium 3 is (c) in the form of a single sealed container 32 in which the sealed container 32 is flexible enough to be bent, and in the form of a single sealed cooling / heating medium 3 in which the cooling / heating agent 31 is accommodated in the single flexible sealed container 32, or (d) in the form of a multiple divided connected sealed container 32 in which the sealed container 32 is flexible enough to be bent and is divided into a plurality of pieces and connected to each other via connecting parts, and in the form of a multiple divided connected sealed cooling / heating medium 3 in which a cooling / heating agent 31 is accommodated in each sealed container 32 of the multiple divided connected sealed containers, A cooling / heating medium 3 is placed in the foam plastic container 20c.

[0133] The above configuration provides the following effect: [Configuration effect 10: By configuring the cooling / heating agent to be contained in a flexible sealed container, it becomes possible to easily design and manufacture the flexible sealed container in a desired shape, and it becomes possible to design a sealed cooling / heating medium in a desired shape that can cover a desired area of ​​an affected part of the human body and cool or heat the desired area, thereby making it possible to efficiently cool or heat the desired area of ​​an affected part of the human body].

[0134] As an example of a cooling / heating device 1 having the above-mentioned configuration "(c) the sealed container 32 has the form of a single sealed container 32 that is flexible enough to bend, and the cooling / heating agent 31 has the form of a single sealed cooling / heating medium 3 that is contained in the flexible single sealed container 32," the cooling / heating medium 3 has the configuration "the cooling / heating medium 3 is in the form of a single sealed cooling / heating medium 3 that is contained in a sealed container 32" as shown in Figures 1(Ca), 2(Ca), 1(Ba), 2(Ba), and 3(Bb). As shown in Figures 1(C) and 2(C), the cooling and heating device 1 has a configuration in which "a sealed cooling and heating medium 3, which is a cooling and heating agent 31 contained in a sealed container 32, is placed in a foam plastic container 20c having a flat surface 20a and a side wall 20b surrounding the flat surface of the container."

[0135] As an example of a cooling / heating device 1 having the above-mentioned configuration "(ii) the sealed container 32 is flexible enough to be bendable, and has the form of a plurality of divided connected sealed containers 32 which are divided into a plurality of pieces and connected to each other via connecting parts, and has the form of a plurality of divided connected sealed cooling / heating medium 3 in which a cooling / heating agent 31 is contained in each sealed container 32 of the plurality of divided connected sealed containers," as shown in (Ca) and (Cb) of Figure 5, the foamed plastic material 20 as the surface member has the form of a plurality of connected foamed plastic storage containers 20d in which a plurality of foamed plastic molded storage containers 20c are connected to each other, and a plurality of divided connected sealed cooling / heating medium 3 is placed in each foamed plastic molded storage container 20c. The divided connected sealed cooling / heating medium 3 has a plurality of divided cooling / heating mediums 3a and a plurality of divided cooling / heating mediums 3b.

[0136] In the subordinate configuration 10, it is preferable to implement a cooling and heating device 1 in which "the foamed plastic material 20 has the form of a multiple connected foamed plastic storage container 20d formed by connecting a plurality of foamed plastic storage containers 20c to each other, a single sealed cooling or heating medium 3 is stored in a desired foamed plastic storage container 20c of the multiple connected foamed plastic storage containers 20d, and a connected sealed cooling or heating medium 3 is stored in another desired foamed plastic storage container 20c of the multiple connected foamed plastic storage container 20d."

[0137] As the above configuration, for example, configurations such as those shown in (Ba) and (Bb) of FIG. 5 can be implemented. In (Ba) and (Bb) of Figure 5, the foamed plastic material 20 as a surface member has the form of a multiple-connected foamed plastic storage container 20d formed by connecting multiple foamed plastic molded storage containers 20c to each other, and multiple divided, connected, sealed cooling and heating media 3 are placed in each foamed plastic molded storage container 20c. The foam plastic molded storage container 20c is provided with a plurality of divided, connected, sealed cooling and heating media 3 having a plurality of divided cooling and heating media 3a and a plurality of divided cooling and heating media 3b, which are divided into a plurality of pieces, and another foam plastic molded storage container 20c is provided with a plurality of divided, connected, sealed cooling and heating media 3 having a plurality of divided cooling and heating media 3a, which are divided into a plurality of pieces, a plurality of divided cooling and heating media 3b and a plurality of divided cooling and heating media 3c, and another foam plastic molded storage container 20c is provided with a single sealed cooling and heating media 3.

[0138] In the above configuration, the sealed container 32 has flexibility to the extent that it can be bent, and has the form of a multiple-divided connected sealed container 32 that is divided into multiple pieces and connected to each other via connecting parts, and is configured so that a cooling / heating agent 31 is contained in each sealed container 32 of the multiple-divided connected sealed container. The plurality of divided, connected sealed cooling / heating mediums 3 are configured to be bendable at their connecting portions.

[0139] In the above configuration, it is preferable to implement a cooling / heating device 1 having a configuration in which "multiple divided, connected, sealed cooling / heating media 3 are contained in a foam plastic container 20c having a large space, and a single sealed cooling / heating media 3 is contained in a foam plastic container 20c having a small space, and the sealed cooling / heating media 3 can be bent to a shape that matches the shape of the surface of the affected part of the human body."

[0140] This configuration achieves the effect of [Configuration Effect 10-i: The sealed cooling / heating medium is bent to a shape that matches the shape of the surface of the affected part of the human body, shortening the distance between the sealed cooling / heating medium and the surface of the affected part of the human body, making it possible to efficiently cool or heat the affected part of the human body].

[0141] The material constituting the sealed container 32 is not particularly limited, but examples thereof include conventional plastic films such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polyamide, polyvinylidene chloride, polyvinyl acetate, etc., aluminum vapor deposition films, aluminum foils, and laminated films of two or more of these.

[0142] Furthermore, the sealed container 32 is preferably a bag-shaped container made of the above-mentioned material, such as a flexible plastic film, or a bag-shaped container made of a metal thin film laminated plastic film containing a flexible metal thin film laminated thereto, and in particular, a bag-shaped container made of a flexible plastic film that can be sealed by heat welding, which makes it possible to easily mass-produce bag-shaped containers of any shape. For example, a flexible plastic laminated film bag-shaped container can be used, which has an inner layer made of heat-sealable polyethylene or polypropylene and an outer layer made of polyamide (nylon) or polyester (polyethylene terephthalate) that has high mechanical strength. Without being limited to this, a plastic laminated film bag-shaped container using polyvinyl chloride, aluminum vapor deposition film, etc. can also be used. The inner polyethylene layer or the inner polypropylene layer is heat-sealable, and film bag containers of any shape can be sealed by heat-sealing, and connecting portions can also be formed by heat-sealing.

[0143] <About cooling and heating devices for the human head> [Subordinate Structure 11] The cooling / heating device of the above-mentioned basic configuration 1 of the present invention preferably has the following configuration. 8 and 9 are schematic diagrams illustrating the configuration of a cooling / heating device according to one embodiment of the present invention. Figure 8 is a schematic cross-sectional view showing the general cross-sectional shape of a cooling / heating device 1 formed so that the affected part of the human body is the human head and can cool or heat the human head, Figure 8(A) is a schematic cross-sectional view of a surface member (2), Figure 8(B) is a schematic cross-sectional view of a cooling / heating medium 3, and Figure 8(C) is a schematic cross-sectional view showing the surface member (2) and the cooling / heating medium 3. Figure 9(B) is a schematic plan view of the cooling / heating device viewed from the inside of the device, Figure 9(A) is a schematic cross-sectional view showing a cross section along line AA of Figure 9(B), and Figure 9(C) is a schematic side view of the cooling / heating device viewed from the side of the device.

[0144] As shown in Figures 8 and 9, the cooling / heating device 1 is a cooling / heating device 1 for cooling or heating an affected part of the human body, and comprises a wearable surface member 2 and a cooling / heating medium 3 placed on the inner surface of the surface member 2. The surface member 2 is at least made of a foamed plastic material 20, and the foamed plastic material 20 is a closed-cell foamed plastic material and / or an open-cell foamed plastic material having porous closed cells and / or open cells. When the cooling / heating device 1 is worn covering the surface of an affected part of the human body, the cooling / heating medium 3 is positioned between the surface member 2 and the affected part of the human body, and is configured to be able to cool or heat the affected part of the human body.

[0145] The affected part of the human body is the head, and the surface member 2 has a form that can be worn to cover the head, and has the form of an approximately hemispherical hollow foamed plastic molding material 21 in which at least a foamed plastic material 20 is formed into an approximately hemispherical hollow shape. The approximately hemispherical hollow foam plastic molding material 21 is formed into a shape that has shape-retaining properties that allow it to maintain its approximately hemispherical hollow shape. The approximately hemispherical hollow foam plastic molding material 21 has an approximately hemispherical hollow shaped surface portion 21a and an approximately hemispherical hollow shaped surface peripheral side wall portion 21b formed around the approximately hemispherical hollow shaped surface portion, and has the form of an approximately hemispherical hollow shaped foam plastic storage container 21c having the form of a storage container formed with an approximately hemispherical hollow shaped foam plastic storage container opening 21e.

[0146] The cooling / heating medium 3 is placed in a substantially semi-spherical hollow foam plastic container 21c. When the cooling / heating device 1 is worn covering the surface of the human head, the side of the approximately hemispherical hollow foamed plastic container opening 21e of the approximately hemispherical hollow foamed plastic container 21c covers the surface of the human head, making it possible to cool or heat the human head.

[0147] The foamed plastic material 20 constituting the above-mentioned approximately hemispherical hollow foamed plastic molding material 21 is not particularly limited, but preferably has a substantially uniform thickness. For example, the thickness of the foamed plastic material 20 is preferably 0.5 to 15 mm, more preferably 1 to 10 mm, and even more preferably 1.5 to 8 mm. As the thickness of the foamed plastic material 20 decreases, the mechanical strength decreases and the ability to maintain a three-dimensional shape tends to decrease, so in this respect, a foamed plastic material having a thickness of 0.5 mm or more is preferred. Also, as the thickness of the foamed plastic material 20 increases, the weight increases and the surface member tends to feel heavy and uncomfortable when attached to the affected part of the human body, so in this respect, a foamed plastic material having a thickness of 15 mm or less is preferred for the foamed plastic material 20. Furthermore, the width dimension of the approximately hemispherical hollow surface peripheral side wall portion 21b formed around the approximately hemispherical hollow surface portion 21a is not particularly limited, but is preferably, for example, about 3 mm to about 30 mm, more preferably 5 mm to 25 mm, and even more preferably 10 mm to 20 mm.

[0148] As shown in Figure 8(A), the "generally hemispherical hollow shape" refers to a shape that has an approximately hemispherical appearance in its overall appearance, a cavity inside the approximately hemispherical shape, and an opening formed in the cavity. In other words, the "generally hemispherical hollow shape" has an overall appearance of a hemisphere, a semi-ellipse, or the like, and has a shape similar to a conventional hat worn to cover the human head. The outer surface shape of the substantially semispherical hollow shaped surface portion 21a is substantially semispherical, and the inner surface shape of the substantially semispherical hollow shaped surface portion 21a is substantially semispherical. The approximately hemispherical hollow plastic storage container 21c formed from the approximately hemispherical hollow surface portion 21a and the approximately hemispherical hollow surface surrounding side wall portion 21b has a configuration having an approximately hemispherical hollow storage portion that can store the cooling medium 3 in an approximately hemispherical hollow shape, as shown in Figures 8(B), (C), 9(A), (B), and (C). That is, as shown in Figure 8(A), the approximately hemispherical hollow foamed plastic container opening 21e of the approximately hemispherical hollow foamed plastic container 21c formed from the approximately hemispherical hollow surface portion 21a and the approximately hemispherical hollow surface surrounding side wall portion 21b has a virtual approximately hemispherical shape shown by the dotted line. 8(B), (C), 9(A), (B), and (C), the cooling medium 3 placed in the substantially hemispherical hollow foam plastic container 21c has a substantially hemispherical shape. That is, the cooling medium is placed in the substantially hemispherical hollow foam plastic container 21c in a substantially hemispherical form.

[0149] The size and shape of the surface member 2, which has an approximately hemispherical hollow shape, is not particularly limited, and it is possible to implement a surface member 2 that can be worn to cover human heads of various sizes so that it approximately matches the size of human heads of various sizes. Furthermore, a surface member 2 that can be worn over the human head and has a shape that allows it to be worn with the ears exposed, without covering the ears located at the sides of the human head, is preferably feasible. Furthermore, the surface member 2 has a shape that can be worn covering the forehead at the front of the human head and / or the area from the back of the head to the back of the neck, and can be worn covering the human head. Furthermore, the surface member 2 having a shape that can be worn to cover the entire hair region of the hair portion of the human head is preferably feasible. Furthermore, the surface shape is not particularly limited, and it is possible to implement a surface member 2 having an approximately hemispherical hollow shape with any desired surface shape, such as a surface shape with irregularities, a smooth surface shape without irregularities, or a surface shape with partial irregularities.

[0150] According to the subsidiary configuration 11, [Configuration effect 11: A cooling and heating device 1 equipped with a cooling and heating medium containing a cooling agent or a heating agent can be easily attached to the human head without the need for an electric cooling mechanism device or an electric heating mechanism device, and when attached to the human head, the external dispersion of cold or warm air caused by the cooling and heating medium containing a cooling agent or a heating agent is suppressed, and the human head is efficiently cooled or heated, thereby achieving the effect of maintaining a comfortable cooling temperature for a long period of time, or maintaining a comfortable warm temperature for a long period of time.Furthermore, when attached to the human head, the human head can be efficiently cooled or heated, and as a result, a cooling and heating device can be obtained that can be expected to have excellent effects such as an excellent "body temperature rise suppression effect when body temperature rises" such as suppressing body temperature rise when the human body develops a fever and preventing heatstroke, or a "warming effect and body temperature retention effect on the human head in cold environments" such as keeping affected parts of the human body warm in severely cold environments and preventing frostbite.

[0151] [Constituent Effect 11-i: In particular, when the cooling / heating device is a cooling / heating medium containing a coolant, it has the above-mentioned "Constituent Effect 11" and, particularly when used as a medical head cooling device, the following effects can be obtained. That is, in particular, when the affected part of the human body is the human head, a cooling / heating device equipped with a cooling / heating medium containing a cooling agent can be easily attached to the human head without the need for an electrical cooling mechanism device, and in applications as a medical head cooling device in which the cooling / heating medium is the cooling medium, the cold air generated by the cooling medium efficiently cools the surface and scalp of the human head, and the cooling performance for cooling the head, such as having a "long duration of comfortable cooling temperature", is excellent, the cooling medium is prevented from falling off the human head, and the wearer's movements are not restricted by the attachment of an electrical cooling mechanism device, and a cooling / heating device having a "comfortable feeling of wearing and a sense of freedom of movement" is obtained, Furthermore, in anti-cancer drug treatment, it is generally known that cooling the scalp surface where hair grows and / or the scalp has a hair loss inhibiting effect that inhibits hair loss caused by anti-cancer drugs administered to cancer patients in chemotherapy. Therefore, when used on a patient who has been administered anti-cancer drugs, it becomes possible to efficiently cool the entire scalp surface where hair grows and / or the scalp, resulting in a cooling / heating device that constricts blood vessels near the hair follicles and / or hair roots, reducing blood flow and reducing the amount of anti-cancer drugs administered to cancer patients in chemotherapy that flow near the hair follicles and / or hair roots, thereby providing a "hair loss inhibiting effect" that can be expected to inhibit hair loss caused by anti-cancer drugs.

[0152] For example, during the hot summer months or outdoors in the blazing sun, the cooling / heating device, which is made up of a cooling agent as the cooling / heating agent 31, can be worn over the head to achieve the effect of "maintaining a comfortable cooling temperature for a long period of time." For example, when a person has a fever due to illness, the effect of "maintaining a comfortable cooling temperature for a long period of time" can be achieved by wearing a cooling / heating device containing a cooling agent as the cooling / heating agent 31 over the head. For example, by wearing the cooling / heating device of the present invention over the head while working or studying, the above-mentioned effect of "maintaining a comfortable cooling temperature for a long period of time" can be achieved. For example, in cold winter seasons, or in seasons with snowfall, cold winds, or other times when the outside temperature is low, by covering the human head with a cooling / heating device that is made up of a heating agent as the cooling / heating agent 31, effects such as the "body temperature keeping effect in a cold environment" described above can be obtained.

[0153] Preferably, when a cooling / heating device comprising a cooling agent as the cooling / heating agent 31 is attached to the human head, the temperature of the inner surface of the cooling / heating device is in the range of approximately 2°C to approximately 15°C (comfortable cooling temperature), and the cooling / heating device can maintain this comfortable cooling temperature range of approximately 2°C to approximately 15°C for 120 minutes or more. That is, a cooling / heating device that maintains a comfortable cooling temperature for 120 minutes or more when attached to the human head is preferably feasible.

[0154] 9, it is also possible to implement a cooling / heating device in which "the affected part of the human body is the human head, and further includes a head-side inner surface member 8 that is configured to be installable on the inner surface of the cooling / heating medium 3 and on the human head side, and the head-side inner surface member 8 is configured to be installable so as to cover the human head when attached to the human head." A cooling / heating device with this configuration will be described in detail later in "Subordinate configuration 25."

[0155] [Subordinate Structure 12] The cooling / heating device 1 according to the aforementioned subsidiary configuration 11 of the present invention preferably has the following configuration. The surface member 2 has a form that can be worn to cover the human head, and at least has the form of an approximately hemispherical hollow foamed plastic molding material 21 in which a foamed plastic material 20 is formed into an approximately hemispherical hollow shape, and the approximately hemispherical hollow foamed plastic molding material 21 has a form that has shape retention that allows it to maintain its approximately hemispherical hollow shape. The surface member 2 can be attached by extending and stretching in the circumferential direction of the approximately hemispherical hollow foamed plastic molding material 21 having an approximately hemispherical hollow shape, and / or in the diameter direction of the approximately hemispherical hollow foamed plastic container opening 21e of the approximately hemispherical hollow foamed plastic container 21c, and / or in the direction from the center of the approximately hemispherical hollow shaped surface portion 21a to the approximately hemispherical hollow shaped surface peripheral side wall portion 21b, when attached to cover the human head. and / or (b) when the container is fitted over the human head with the cooling / heating medium 3 contained therein, the side wall portion 21b around the approximately hemispherical hollow surface of the foamed plastic container 21c is compressed and / or stretched to adhere closely to and / or come into contact with the surface of the human head, and has such elasticity that it returns to its original shape when the force is removed, thereby suppressing the cold or warm air from escaping outward from the surface member 3.

[0156] In the above configuration, the surface member 2 is preferably flexible enough at room temperature to be bent at an angle of 90 degrees without breaking when force is applied, and to return to its original angle when the force is removed; when worn to cover the human head, it can be stretched by at least about 3%, preferably at least about 5%, and more preferably at least about 10% in the circumferential direction of the approximately hemispherical hollow foamed plastic storage container 21c of the approximately hemispherical hollow foamed plastic molding material 21 having an approximately hemispherical hollow shape, and / or in the diametric direction of the approximately hemispherical hollow foamed plastic storage container opening 21e of the approximately hemispherical hollow foamed plastic storage container 21c, and / or in the direction from the center of the approximately hemispherical hollow shaped surface portion 21a to the approximately hemispherical hollow shaped surface peripheral side wall portion 21b; and is formed so as to be able to contract to its original shape when worn to cover the human head. For example, in the case of a cooling / heating device in which the peripheral length of the substantially hemispherical hollow plastic foam container 21c is approximately 60 cm, it is preferable that the device be extendable to a length of approximately 18 mm or more in the peripheral direction of the substantially hemispherical hollow plastic foam container 21c, and be able to contract to its original length when worn over the human head. Also, it is preferable that the surface member 2 contracts in a direction that compresses the human head when it contracts to its original length.

[0157] In addition, in the subordinate configuration 12, the "circumferential direction of the approximately hemispherical hollow foam plastic molding material 21" and / or the "diameter direction of the approximately hemispherical hollow foam plastic container opening 21e" refer to the circumferential direction passing through the forehead, temporal region, and occipital region of the human head when the cooling / heating device is attached to the human head. "The direction from the center of the approximately hemispherical hollow surface portion 21a to the peripheral side wall portion 21b of the approximately hemispherical hollow surface" means the direction from the top of the head to the forehead, ears, and back of the head when the cooling / heating device is attached to the head. "The circumferential direction of the approximately hemispherical hollow foamed plastic molding material 21" means "the circumferential direction of the approximately hemispherical hollow foamed plastic storage container 21c of the approximately hemispherical hollow foamed plastic molding material 21." "The diameter direction of the approximately hemispherical hollow foamed plastic storage container opening 21e of the approximately hemispherical hollow foamed plastic storage container 21c" means "the diameter direction of the approximately hemispherical hollow foamed plastic storage container opening 21e of the approximately hemispherical hollow foamed plastic molding material 21."

[0158] In the above configuration, the surface member 2 is preferably formed so that it can be worn over the human head and / or can be worn over the human head without breaking and / or being damaged. Preferably, the surface member 2 is a foamed plastic material 20 that has the property of expanding without breaking or damaging when force is applied, and contracting to its original length without breaking or damaging when the force is removed.

[0159] As the foamed plastic material 20 constituting the surface member 2 that is extensible, contractible, and flexible, at least one foamed plastic material 20 selected from the group consisting of foamed polyolefin resin, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer obtained by copolymerizing ethylene monomer with other vinyl monomer, foamed polyvinyl acetate, foamed natural rubber, foamed nitrile rubber, foamed nitrile-butadiene rubber, foamed chloroprene rubber, foamed silicone rubber, foamed ethylene-propylene rubber, foamed polyvinyl chloride, foamed polyvinyl alcohol, foamed polypropylene, foamed polyurethane, foamed polyacrylic, foamed ethylene propylene diene rubber, and foamed ester-based elastomer, as will be described in the "subordinate configuration 29" below, can be preferably implemented. As the foamed plastic material 20 constituting the surface member 2, which is stretchable, contractible and flexible, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer copolymerized with ethylene monomer and other vinyl monomer, or foamed polyvinyl acetate are particularly preferred.

[0160] This configuration provides the aforementioned "Configuration Effect 11," as well as "Configuration Effect 12: The approximately hemispherical hollow foamed plastic molding material 21 is formed to be stretchable and contractible in the circumferential direction of the opening of the approximately hemispherical hollow shape and / or in the plane direction of the approximately hemispherical hollow shape, so that when it is attached to the human head, the opening of the cooling / heating device 1 can be easily attached in a stretched and widened state, and when the force is released after it is attached to the human head, the opening of the cooling / heating device 1 shrinks to its original length, thereby providing the effect of preventing the cooling / heating device 1 from falling off the human head. Furthermore, in particular, by covering the human head and wearing it stretched in the surface direction from the opening of the approximately hemispherical hollow shape to the center, the approximately hemispherical hollow foam plastic molding material 21 contracts in a direction that compresses the human head via the cooling / heating medium 3, and the cooling / heating medium 3 is compressed toward the human head, causing the approximately hemispherical hollow shaped peripheral side wall portion (21b) of the approximately hemispherical hollow foam plastic storage container 21c to compress and / or expand and come into close contact with and / or adhere to the surface of the human head, thereby suppressing the cold or warm air from escaping in the outward direction of the surface member 3, and achieving the effect of efficiently cooling or heating the human head by the cooling / heating medium 3.

[0161] [Subordinate Structure 13] The cooling / heating device 1 according to the aforementioned subsidiary configuration 11 of the present invention preferably has the following configuration.

The cooling / heating device 1 of the present invention is a cooling / heating device 1 for cooling or heating an affected part of the human body, and comprises a surface member 2 and a cooling / heating medium 3 placed on the inner surface side of the surface member 2, the surface member 2 being composed of at least a foamed plastic material 20, which is a closed-cell foamed plastic material having porous closed cells and / or an open-cell foamed plastic material having porous open cells, and when the surface member 2 is attached to cover the surface of the affected part of the human body, the cooling / heating medium 3 is located between the surface member 2 and the affected part of the human body, and is configured to be able to cool or heat the affected part of the human body (basic configuration 1).

[0188] In the cooling / heating device 1 of the present invention, in this configuration (basic configuration 1), the affected part of the human body is the human head, the surface member 2 has a form that can be worn to cover the human head, and at least the foamed plastic material 20 has the form of a connected approximately hemispherical hollow foamed plastic molding material 22 formed into an approximately hemispherical hollow shape, and the connected approximately hemispherical hollow foamed plastic molding material 22 has a shape that has shape-retaining ability to maintain the approximately hemispherical hollow shape, and the connected approximately hemispherical hollow foamed plastic molding material 22 has at least a multiple connected approximately hemispherical hollow foamed plastic container 22c formed by connecting a plurality of connected hemispherical foamed plastic containers 22c to each other.

[0189] The term "generally hemispherical hollow shape" refers to a shape that has an approximately hemispherical appearance in its overall appearance, a hollow inside the approximately hemispherical shape, and an opening formed in the hollow. In other words, the "generally hemispherical hollow shape" has an overall appearance of a hemisphere, a semi-ellipse, or the like, and is similar in shape to a conventional hat worn to cover the human head. The size and shape of the surface member 2, which has an approximately hemispherical hollow shape, is not particularly limited, and it is possible to implement a surface member 2 that can be worn to cover human heads of various sizes so that it approximately matches the size of human heads of various sizes. Furthermore, a surface member 2 that can be worn over the human head and has a shape that allows it to be worn with the ears exposed, without covering the ears located at the sides of the human head, is preferably feasible. Furthermore, the surface member 2 has a shape that can be worn covering the forehead at the front of the human head and / or the area from the back of the head to the back of the neck, and can be worn covering the human head. Furthermore, the surface member 2 having a shape that can be worn to cover the entire hair region of the hair portion of the human head is preferably feasible. Furthermore, the surface shape is not particularly limited, and it is possible to implement a surface member 2 having an approximately hemispherical hollow shape with any desired surface shape, such as a surface shape with irregularities, a smooth surface shape without irregularities, or a surface shape with partial irregularities.

[0190] Each of the foamed plastic storage containers 22c for connected hemispheres has a planar shape that is circular, elliptical, triangular, square, pentagonal, hexagonal, or other polygonal, and a cross-sectional shape that is semicircular, rectangular, square, trapezoidal, etc., and the inner surface shape of each of the foamed plastic storage containers 22c for connected hemispheres has a configuration in the form of a storage container having a container portion 22h for the head of the connected hemispheres with a recessed depression formed therein and a foamed plastic storage container opening 22e for the hemispheres.

[0191] For example, as each of the foamed plastic storage containers 22c for connected hemispheres, as shown in (A) and (Aa) of Figures 4A and 4B, a foamed plastic storage container 20c can be implemented that has a circular or elliptical shape in plan view, has a circular or elliptical foamed plastic storage container opening 20e, is approximately arc-shaped in cross section, and has a three-dimensional recessed storage portion.

[0192] For example, as shown in Figures 4(B) and (Ba), each of the foam plastic storage containers 22c for connected semi-circular spheres can be a foam plastic storage container 20c that has a polygonal shape in plan view and a three-dimensional recessed storage section in cross section, which has a storage container section 20h that has a storage container flat surface section 20a and a storage container flat surface peripheral side wall section 20b formed at an approximately perpendicular angle around the storage container flat surface section, and a foam plastic storage container opening 20e. Also, in Figure 4(Ba), a configuration in which the storage container flat surface section 20a is circular or elliptical instead of polygonal can be implemented.

[0193] As shown in Figures 4(C) and (Ca) above, a foamed plastic storage container 20c can be implemented, which has a polygonal shape in plan view and a three-dimensional recessed storage portion in cross section, including a storage container portion 20h having a storage container flat surface portion 20a and a storage container flat surface peripheral side wall portion 20b formed at a desired angle around the storage container flat surface portion, and a foamed plastic storage container opening 20e. In Figure 4(Ca), a configuration in which the storage container flat surface portion 20a is circular or elliptical instead of polygonal can also be implemented. Note that Figures 4(C) and (Ca) preferably implement a foamed plastic storage container 20c, which has a polygonal shape in plan view and a three-dimensional recessed storage portion in cross section, including a storage container portion 20h having a storage container flat surface portion 20a and a storage container flat surface peripheral side wall portion 20b formed at an angle around the storage container flat surface portion toward the opening, and a foamed plastic storage container opening 20e.

[0194] 4(D) and (Da), a foamed plastic storage container 20c can be implemented that has a desired cross shape in plan view and a three-dimensional recessed storage section in cross section, with a storage container section 20h having a storage container flat surface section 20a and a storage container flat surface peripheral side wall section 20b formed around the storage container flat surface section, and a foamed plastic storage container opening 20e. Note that the foamed plastic storage container 20c is not limited to one having a cross shape in plan view, and can be implemented in any desired shape, such as a heart shape, a star shape, or any other desired shape.

[0195] As shown in (E) and (Ea) of Figure 4 above, a foamed plastic storage container 20c can be implemented that has a circular or elliptical shape in plan view, and in cross section, has a storage container portion 20h that has a storage container flat surface portion 20a and a storage container flat surface peripheral side wall portion 20b that is formed in an approximately arc-shaped or linear shape around the storage container flat surface portion, and has a three-dimensional recessed storage portion that has a foamed plastic storage container opening 20e.

[0196] In the foamed plastic storage container 20c shown in FIG. 4, the flat surface portion 20a of the storage container and the foamed plastic storage container opening 20e are preferably configured to have the same shape or similar shapes.

[0197] As described above, "each of the foamed plastic storage containers 22c for connected hemispheres of the plurality of foamed plastic storage containers 22c for connected hemispheres" in the invention of this dependent configuration 17 comprises a foamed plastic storage container 22c for connected hemispheres having a shape similar to the foamed plastic storage container 20c described above in Figure 4. The surface member 2 has a plurality of foamed plastic storage containers 22c for connected hemispheres, and has the overall shape of a connected, approximately hemispherical, hollow foamed plastic molding material 22 formed into an approximately hemispherical hollow shape. The connected, approximately hemispherical, hollow foamed plastic molding material 22 formed as an overall shape is formed into a shape that has shape retention that maintains the approximately hemispherical hollow shape, and the connected, approximately hemispherical, hollow foamed plastic molding material 22 has the form of at least a plurality of connected, approximately hemispherical, hollow foamed plastic storage containers 22d formed by connecting a plurality of foamed plastic storage containers 22c for connected hemispheres to each other.

[0198] The thickness of the foamed plastic material 20 constituting the connected substantially hemispherical hollow foamed plastic molded material 22 is preferably 0.5 to 15 mm, more preferably 1 to 10 mm, and even more preferably 1.5 to 8 mm. As the thickness of the foamed plastic material 20 decreases, the mechanical strength decreases and the ability to maintain a three-dimensional shape tends to decrease, so in this respect, a foamed plastic material having a thickness of 0.5 mm or more is preferred. Also, as the thickness of the foamed plastic material 20 increases, the weight increases and the surface member tends to feel heavy and uncomfortable when attached to the affected part of the human body, so in this respect, a foamed plastic material having a thickness of 15 mm or less is preferred for the foamed plastic material 20.

[0199] The cooling and heating medium 3 can be a shape-retaining sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in "subordinate configuration 23" below, is contained in a sealed container 32, or a flexible sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in "subordinate configuration 24" below, is contained in a sealed container 32.

[0200] FIG. 13 is a schematic diagram illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention. The cooling and heating device 1 shown in Figure 13 is a schematic cross-sectional view showing the general cross-sectional shape of the cooling and heating device 1, which is configured to be able to cool or heat the human head, and in which each of the multiple connected foam plastic storage containers 22c for connected hemispheres has an approximately circular planar shape and a shape with an approximately hemispherical recess. Figure 13(A) is a schematic cross-sectional view of the surface member 2, Figure 13(Bc) is a schematic cross-sectional view of the cooling and heating medium 3, and Figure 13(C) is a schematic cross-sectional view showing the surface member 2 and the cooling and heating medium 3. Figures 13(Ba), 13(Bb), and 13(Bc) are schematic cross-sectional diagrams of the cooling / heating medium 3, where Figure 13(Ba) shows a shape-retaining container 32c, Figure 13(Bb) shows a cooling / heating agent, and Figure 13(Bc) shows the configuration of the cooling medium 3 in which a cooling / heating agent 31 is contained in a shape-retaining container 32c.

[0201] As shown in Figure 13, the cooling / heating device 1 is a cooling / heating device 1 for cooling or heating an affected part of the human body, and comprises a surface member 2 and a cooling / heating medium 3 placed on the inner surface side of the surface member 2. The surface member 2 is made up of at least a foamed plastic material 20, and the foamed plastic material 20 is a closed-cell foamed plastic material and / or an open-cell foamed plastic material having porous closed cells and / or open cells. When the cooling / heating device 1 is worn covering the surface of an affected part of the human body, the cooling / heating medium 3 is positioned between the surface member 2 and the affected part of the human body, and is configured to be able to cool or heat the affected part of the human body.

[0202] The affected part of the human body is the human head, and the surface member 2 has a form that can be worn to cover the human head, and at least the foamed plastic material 20 has the form of a connected approximately hemispherical hollow foamed plastic molding material 22 formed into an approximately hemispherical hollow shape, and the connected approximately hemispherical hollow foamed plastic molding material 22 is formed into a form that has shape retention that maintains the approximately hemispherical hollow shape. As shown in Figure 13(A), the connected, approximately hemispherical, hollow foamed plastic molding material 22 has at least the form of a multiple connected, approximately hemispherical, hollow foamed plastic storage container 22d, which is formed by connecting multiple connected hemispherical foamed plastic storage containers 22c to each other.

[0203] The inner surface shape of each of the multiple foamed plastic storage containers 22c for connected hemispheres has the form of a storage container having a container portion 22h for the head of the connected hemispheres with a recessed depression formed therein and a foamed plastic storage container opening 22e for the hemispheres. For example, as shown in Figure 13(A), the inner surface shape of each connected hemisphere foam plastic storage container 22c has an inner surface shape with an approximately hemisphere-shaped recessed depression, and has the form of a storage container having a hemisphere foam plastic storage container opening 22e.

[0204] That is, the connected, approximately hemispherical, hollow foamed plastic molding material 22 as a surface member has the form of a plurality of connected, approximately hemispherical, hollow foamed plastic storage containers 22d formed by connecting a plurality of connected, hemispherical, foamed plastic storage containers 22c to each other, and the inner shape of each connected, hemispherical, foamed plastic storage container 22c has an inner shape with an approximately hemispherical, recessed portion, and has the form of a storage container having a hemispherical, foamed plastic storage container opening 22e.

[0205] As shown in FIG. 13(C), the cooling / heating medium 3 as shown in FIG. 13(Bc) is placed in each of the connected semi-spherical foam plastic containers 22c. When the cooling / heating device 1 is worn covering the surface of the human head, the side of the foamed plastic container for connected hemispheres 22c, which is made of foamed plastic and has an opening 22e for the container, covers the surface of the human head, making it possible to cool or heat the human head.

[0206] As the cooling / heating medium 3, a configuration comprising a sealed container 32 having a shape-retaining container 32c having enough shape retention to maintain the shape as shown in Figure 13 (Ba) and a shape-retaining container sealing cover 32e that can cover and seal the opening of the shape-retaining container 32c, and a cooling / heating agent 31 contained in the sealed container 32, can be preferably implemented. In this case, the shape-retaining container 32c can preferably be a shape-retaining container 32c having an outer shape that is approximately hemispherical and that roughly matches the inner shape of each connected hemispherical foam plastic storage container 22c, as shown in Figure 13 (Ba).

[0207] Although not shown, the cooling / heating medium 3 may preferably be a cooling / heating agent 31 contained in a flexible sealed container. In Figure 13, "symbol 22k" refers to "connected semispherical hollow molded material opening end protrusion member 22k that protrudes toward the opening at the periphery of the end of the connected semispherical hollow foamed plastic molded material located on the opening side of the connected semispherical hollow foamed plastic molded material 22," which will be described in "subordinate configuration 40" below, and a surface member on which the connected semispherical hollow molded material opening end protrusion member 22k is formed can also be preferably implemented.

[0208] With this configuration, [Configuration Effect 17: A cooling and heating device 1 equipped with a cooling and heating medium containing a cooling agent or a heating agent can be easily attached to the human head without the need for an electric cooling mechanism device or an electric heating mechanism device, and when attached to the human head, the external dispersion of cold or warm air caused by the cooling and heating medium containing a cooling agent or a heating agent is suppressed, and the human head is efficiently cooled or heated, achieving the effect of maintaining a comfortable cooling temperature for a long period of time, or maintaining a comfortable warm temperature for a long period of time.Furthermore, when attached to the human head, the cooling and heating device 1 can be efficiently cooled or heated, resulting in an excellent "body temperature rise suppression effect when body temperature rises," such as suppressing body temperature rise when the body develops a fever and preventing heatstroke, or a "warming effect and body temperature retention effect on the human head in cold environments," such as keeping affected parts of the body warm in severely cold environments and preventing frostbite, etc. Furthermore, the connected, approximately hemispherical, hollow foam plastic molding material 22 has the form of multiple connected, approximately hemispherical, hollow foam plastic storage containers 22d formed by connecting at least multiple connected, approximately hemispherical, hollow foam plastic storage containers 22c to each other, and a cooling / heating medium 3 is placed in each of the hemispherical foam plastic storage containers 22c.This configuration makes it possible to easily store the cooling / heating medium 3 in a desired hemispherical foam plastic storage container 22c out of the multiple connected hemispherical foam plastic storage containers 22c, making it possible to efficiently cool or heat a desired part of the human head, and also makes it easier to store and remove the cooling / heating medium 3 from the hemispherical foam plastic storage container 22c.

[0209] Furthermore, when the cooling / heating device 1 of the present invention is used in anti-cancer drug treatment as a medical head cooling device, the following [Constituent Effect 17-A] can be obtained. [Configuration Effect 17-i: The above-mentioned "Configuration Effect 17" can be obtained, and further, in particular, when the affected part of the human body is the human head, a cooling / heating device 1 equipped with a cooling / heating medium containing a coolant can be easily attached to the human head without the need for an electrical cooling mechanism device, and in applications as a medical head cooling device having a configuration in which the cooling / heating medium is the cooling medium, the cold air generated by the cooling medium efficiently cools the surface of the human head and scalp, and the cooling performance for cooling the head, such as having "long duration of cooling comfort temperature", is excellent, the cooling medium is prevented from falling off the human head, and the wearer's movements are not restricted by the attached electrical cooling mechanism, and the cooling / heating device 1 has "a comfortable feeling of wearing and a sense of freedom of movement", such as being able to move freely. Furthermore, in anti-cancer drug treatment, it is generally known that cooling the scalp surface where hair grows and / or the scalp has a hair loss suppression effect that suppresses hair loss caused by anti-cancer drugs administered to cancer patients in chemotherapy. Therefore, when used on a patient who has been administered anti-cancer drugs, it becomes possible to efficiently cool the entire scalp surface where hair grows and / or the scalp, resulting in the contraction of blood vessels near the hair follicles and / or hair roots, reducing blood flow and reducing the amount of anti-cancer drugs administered to cancer patients in chemotherapy that flow near the hair follicles and / or hair roots, thereby obtaining a cooling / heating device 1 that can be expected to have a "hair loss suppression effect" that suppresses hair loss caused by anti-cancer drugs.

[0210] For example, during the hot summer months or outdoors in the blazing sun, the cooling and heating device 1, which is made up of a cooling agent as the cooling and heating agent 31, can be worn over the head to achieve the effect of "maintaining a comfortable cooling temperature for a long period of time." For example, when a person has a fever due to illness, the cooling / heating device 1, which is made up of a cooling agent as the cooling / heating agent 31, can be worn over the head to achieve the effect of "maintaining a comfortable cooling temperature for a long period of time." For example, by wearing the cooling / heating device 1 of the present invention over the head while working or studying, the above-mentioned effect of "maintaining a comfortable cooling temperature for a long period of time" can be achieved.

[0211] For example, in cold winter seasons, or in seasons with snowfall or cold winds when the outside temperature is low, by covering the head with the cooling / heating device 1, which is made up of a heating agent as the cooling / heating agent 31, the above-mentioned effects such as "body temperature retention effect in cold environments" and "long-term maintenance of comfortable thermal temperature" can be obtained.

[0212] Preferably, when the cooling / heating device 1, which uses a cooling agent as the cooling / heating agent 31, is worn on the human head, the temperature of the inner surface of the cooling / heating device 1 or the temperature of the cooling agent is in the range of about 2°C to about 15°C, and this temperature of about 2°C to about 15°C is maintained for 120 minutes or more. That is, when worn on the human head, the cooling / heating device 1 is preferably one which provides a comfortable cooling temperature of about 2°C to about 15°C, and the "comfortable cooling temperature duration" during which this temperature range of about 2°C to about 15°C is maintained for 120 minutes or more.

[0213] In this configuration, the external shape of the approximately hemispherical hollow shape in the foamed plastic material 20 having the form of the connected approximately hemispherical hollow foamed plastic molding material 22 formed into an approximately hemispherical hollow shape can be a shape having an external shape with unevenness formed by a plurality of approximately semicircular shapes roughly similar to the inner shape of each connected hemispherical foamed plastic storage container 22c, as shown in Figure 13(A), or a shape having an external shape with an approximately semicircular shape, although not shown.

[0219] As shown in Figure 14, the cooling / heating device 1 is a cooling / heating device 1 for cooling or heating an affected part of the human body, and comprises a surface member 2 and a cooling / heating medium 3 placed on the inner surface side of the surface member 2. The surface member 2 is made up of at least a foamed plastic material 20, and the foamed plastic material 20 is a closed-cell foamed plastic material and / or an open-cell foamed plastic material having porous closed cells and / or open cells. When the cooling / heating device 1 is worn covering the surface of an affected part of the human body, the cooling / heating medium 3 is positioned between the surface member 2 and the affected part of the human body, and is configured to be able to cool or heat the affected part of the human body.

[0221] That is, the connected, approximately hemispherical, hollow foam plastic molding material 22 serving as the surface member has the form of a plurality of connected, approximately hemispherical, hollow foam plastic storage containers 22d formed by connecting together a plurality of connected, hemispherical, foam plastic storage containers 22c, and the inner shape of each connected, hemispherical, foam plastic storage container 22c has the form of a storage container that forms a flat surface portion 22a of the connected, hemispherical, head storage container and a flat surface peripheral side wall portion 22b of the connected, hemispherical, head storage container formed around the flat surface portion of the connected, hemispherical, head storage container, and has the form of a storage container with a connected, hemispherical, foam plastic storage container opening 22e.

Note that the foamed plastic storage container 20c is not limited to one having a cross shape in plan view, and can be implemented in any desired shape, such as a heart shape, a star shape, an animal pattern shape, a plant pattern shape, or any other desired shape.

[0226] Each of the foamed plastic storage containers 22c for connected hemispheres among the multiple foamed plastic storage containers 22c for connected hemispheres can be implemented as a foamed plastic storage container 20c that has a circular or elliptical shape in plan view, as shown in (E) and (Ea) of Figure 4 above, and in cross section, has a storage container portion 20h having a storage container flat surface portion 20a and a storage container flat surface peripheral side wall portion 20b formed in an approximately arc-shaped or linear shape around the storage container flat surface portion, and a foamed plastic storage container opening 20e, in the form of a three-dimensional recessed storage container.

[0227] In Figure 14, "symbol 22k" refers to "connected semispherical hollow molded material opening end protrusion member 22k that protrudes toward the opening at the periphery of the end of the connected semispherical hollow foamed plastic molded material located on the opening side of the connected semispherical hollow foamed plastic molded material 22," which will be described in "subordinate configuration 40" below, and a surface member on which the connected semispherical hollow molded material opening end protrusion member 22k is formed can also be preferably implemented.

[0228] In the foamed plastic storage container 20c shown in FIG. 4, the flat surface portion 20a of the storage container and the foamed plastic storage container opening 20e are preferably configured to have the same shape or similar shapes.

[0229] As described above, "each of the foamed plastic storage containers 22c for connected hemispheres of the plurality of foamed plastic storage containers 22c for connected hemispheres" in the invention of this dependent configuration 18 comprises a foamed plastic storage container 22c for connected hemispheres having a shape similar to the foamed plastic storage container 20c described above in Figure 4. The surface member 2 has a plurality of connected hemispherical foam plastic storage containers 22c, and has the form of a connected approximately hemispherical hollow foam plastic molding material 22 formed into an approximately hemispherical hollow shape. The connected approximately hemispherical hollow foam plastic molding material 22 is formed into a shape that has shape retention properties that allow it to maintain the approximately hemispherical hollow shape, and the connected approximately hemispherical hollow foam plastic molding material 22 has the form of a multiple connected approximately hemispherical hollow foam plastic storage container 22d, which is formed by at least a plurality of connected hemispherical foam plastic storage containers 22c connected to each other.

[0230] The cooling / heating medium 3 is placed in each of the connected semi-spherical foam plastic containers 22c. When the cooling / heating device 1 is worn covering the surface of the human head, the side of the connecting semi-circular foam plastic container 22c, which is the opening 22e of the connecting semi-circular foam plastic container, covers the surface of the human head, so that the human head can be cooled or heated. In this case, the shape-retaining container 32c can preferably be a shape-retaining container 32c having an outer shape formed by a flat surface portion 22a of the container for heads of connected hemispheres that roughly matches the inner shape of each foam plastic container for heads of connected hemispheres 22c, and a flat surface peripheral side wall portion 22b of the container for heads of connected hemispheres that is formed around the flat surface portion of the container for heads of connected hemispheres.

[0231] For example, as shown in FIG. 14(C), a cooling / heating medium 3 as shown in FIG. 14(Bc) is placed in each of the connected semi-spherical foam plastic containers 22c. In this case, the shape-retaining container 32c can preferably be a shape-retaining container 32c having an outer shape formed by a flat surface portion 22a of the container for heads of connected hemispheres that roughly matches the inner shape of each foam plastic container for heads of connected hemispheres 22c, and a flat surface peripheral side wall portion 22b of the container for heads of connected hemispheres formed around the flat surface portion of the container for heads of connected hemispheres, as shown in Figure 14(Ba) or Figure 17(A).

[0232] With this configuration, [Configuration Effect 18: A cooling and heating device 1 equipped with a cooling and heating medium containing a cooling agent or a heating agent can be easily attached to the human head without the need for an electric cooling mechanism device or an electric heating mechanism device, and when attached to the human head, the external dispersion of cold or warm air caused by the cooling and heating medium containing a cooling agent or a heating agent is suppressed, and the human head is efficiently cooled or heated, achieving the effect of maintaining a comfortable cooling temperature for a long period of time, or maintaining a comfortable warm temperature for a long period of time.Furthermore, when attached to the human head, the cooling and heating device 1 can be efficiently cooled or heated, resulting in an excellent "body temperature rise suppression effect when body temperature rises," such as suppressing body temperature rise when the human body develops a fever and preventing heatstroke, or a "warming effect and body temperature retention effect on the human head in cold environments," such as keeping affected parts of the body warm in severely cold environments and preventing frostbite, etc. Furthermore, the connected, approximately hemispherical, hollow foam plastic molding material 22 has the form of multiple connected, approximately hemispherical, hollow foam plastic storage containers 22d formed by connecting at least multiple connected, approximately hemispherical, hollow foam plastic storage containers 22c to each other, and a cooling / heating medium 3 is placed in each of the hemispherical foam plastic storage containers 22c.This configuration makes it possible to easily store the cooling / heating medium 3 in a desired hemispherical foam plastic storage container 22c out of the multiple connected hemispherical foam plastic storage containers 22c, making it possible to efficiently cool or heat a desired part of the human head, and also makes it easier to store and remove the cooling / heating medium 3 from the hemispherical foam plastic storage container 22c. Furthermore, "it is possible to form foamed plastic storage containers 22c for connected hemispheres that have a large area ratio relative to the total area of ​​the surface member, and it is possible to place a cooling or heating medium in each foamed plastic storage container 22c for connected hemispheres, thereby making it possible to minimize the area where a cooling or heating medium is not placed, and a cooling or heating device 1 is obtained that can efficiently cool or heat the entire human head."

[0233] [Configuration Effect 18-i: In particular, when the affected part of the human body is the human head, a cooling / heating device 1 equipped with a cooling / heating medium containing a coolant can be easily attached to the human head without the need for an electrical cooling mechanism device, and in applications as a medical head cooling device having a configuration in which the cooling / heating medium is the cooling medium, the cold air caused by the cooling medium efficiently cools the surface of the human head and scalp, and the cooling performance for cooling the head, such as having a "long duration of comfortable cooling temperature", is excellent, the cooling medium is prevented from falling off the human head, and the wearer's movements are not restricted by the attachment of an electrical cooling mechanism device, and the cooling / heating device 1 has a "comfortable feeling of wearing and a sense of freedom of movement", such as being able to move freely. Furthermore, in anti-cancer drug treatment, it is generally known that cooling the scalp surface where hair grows and / or the scalp has a hair loss suppression effect that suppresses hair loss caused by anti-cancer drugs administered to cancer patients in chemotherapy. Therefore, when used on a patient who has been administered anti-cancer drugs, it becomes possible to efficiently cool the entire scalp surface where hair grows and / or the scalp, resulting in the contraction of blood vessels near the hair follicles and / or hair roots, reducing blood flow and reducing the amount of anti-cancer drugs administered to cancer patients in chemotherapy that flow near the hair follicles and / or hair roots, thereby obtaining a cooling / heating device 1 that can be expected to have a "hair loss suppression effect" that suppresses hair loss caused by anti-cancer drugs.

[0234] For example, a cooling / heating device 1 having a configuration that forms an approximately hemispherical hollow shape made up of multiple triangles can minimize the area where cooling / heating agents are not placed, resulting in a cooling / heating device 1 that can cool or heat and achieves the effects of the above-mentioned "Configuration Effect 18" and "Configuration Effect 18-i." In particular, the cooling and heating device 1 has a configuration in which a plurality of triangles are combined to form an approximately hemispherical hollow shape, and the foamed plastic storage containers 22c for the connected hemispherical triangles are less likely to deform, resulting in a cooling and heating device 1 with significantly improved effectiveness in maintaining the approximately hemispherical hollow shape of the connected approximately hemispherical hollow foamed plastic molding material 22.

[0235] The term "generally hemispherical hollow shape" refers to a shape that has an approximately hemispherical appearance in its overall appearance, a hollow inside the approximately hemispherical shape, and an opening formed in the hollow. In other words, the "generally hemispherical hollow shape" has an overall appearance of a hemisphere, a semi-ellipse, or the like, and is similar in shape to a conventional hat worn to cover the human head. The size and shape of the surface member 2, which has an approximately hemispherical hollow shape, is not particularly limited, and it is possible to implement a surface member 2 that can be worn to cover human heads of various sizes so that it approximately matches the size of human heads of various sizes.

[0236] Furthermore, a surface member 2 that can be worn over the human head and has a shape that allows it to be worn with the ears exposed, without covering the ears located at the sides of the human head, is preferably feasible.

[0237] Furthermore, the surface member 2 has a shape that can be worn covering the forehead at the front of the human head and / or the area from the back of the head to the back of the neck, and can be worn covering the human head.

[0238] Furthermore, the surface member 2 having a shape that can be worn to cover the entire hair region of the hair portion of the human head is preferably feasible.

[0239] Furthermore, the surface shape is not particularly limited, and it is possible to implement a surface member 2 having an approximately hemispherical hollow shape with any desired surface shape, such as a surface shape with irregularities, a smooth surface shape without irregularities, or a surface shape with partial irregularities.

[0240] In addition, in this configuration, the external shape of the approximately hemispherical hollow shape in the foamed plastic material 20 having the form of a connected approximately hemispherical hollow foamed plastic molding material 22 formed into an approximately hemispherical hollow shape can be a shape having an external shape with unevenness formed by a plurality of approximately semicircular shapes roughly similar to the inner shape of each connected hemispherical foamed plastic storage container 22c, as shown in Figure 14(A), or a shape having an external shape with an approximately semicircular shape, as shown in Figure 17(A).

[0241] [Subordinate Structure 19] The cooling / heating device 1 of the aforementioned "subordinate configuration 18" of the present invention preferably has the following configuration. The cooling / heating device 1 has a configuration in which "the inner surface shape of each of the plurality of connected hemisphere foam plastic storage containers 22c has a flat surface portion 22a for the connected hemisphere heads and a side wall portion 22b around the flat surface of the connected hemisphere head storage container formed at an angle widening from the flat surface portion 22a for the connected hemisphere heads toward the connected hemisphere foam plastic storage container opening 22e, and has the form of a storage container with the connected hemisphere foam plastic storage container opening 22e formed therein, and a cooling / heating medium 3 is placed in each connected hemisphere foam plastic storage container 22c, and when the connected hemisphere foam plastic storage container 22c is worn covering the surface of the affected part of the human body, the side of the connected hemisphere foam plastic storage container opening 22e covers the surface of the affected part of the human body, allowing the affected part of the human body to be cooled or heated."

[0242] The cooling and heating medium 3 can be a shape-retaining sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in "subordinate configuration 23" below, is contained in a sealed container 32, or a flexible sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in "subordinate configuration 24" below, is contained in a sealed container 32.

[0243] FIG. 14 is a schematic diagram illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention. Figure 14 is a schematic cross-sectional view showing the general cross-sectional shape of a cooling / heating device 1 formed so that the affected part of the human body is the human head and can cool or heat the human head, Figure 14(A) is a schematic cross-sectional view of a surface member 2, Figures 14(Ba), (Bb), and (Bc) are schematic cross-sectional views of a cooling / heating medium 3, and Figure 14(C) is a schematic cross-sectional view showing the surface member 2 and the cooling / heating medium 3. As shown in Figure 14(A), the inner surface shape of each of the multiple foam plastic storage containers 22c for connected hemispheres comprises a flat surface portion 22a of the container for heads of connected hemispheres and a side wall portion 22b surrounding the flat surface of the container for heads of connected hemispheres, which is formed at an angle that widens from the flat surface portion 22a of the container for heads of connected hemispheres toward the opening 22e of the container for heads of connected hemispheres made of foam plastic. The cooling / heating medium 3 is placed in each of the connected semi-spherical foam plastic containers 22c.

[0244] In addition, the structure of the present invention, "the inner surface shape of each of the plurality of foam plastic storage containers 22c for connected hemispheres has a flat surface portion 22a for the heads of the connected hemispheres and a side wall portion 22b around the flat surface of the storage container for connected hemispheres that is formed at an angle widening from the flat surface portion 22a for the heads of the connected hemispheres toward the opening 22e of the foam plastic storage container for connected hemispheres, and has the shape of a storage container with the opening 22e of the foam plastic storage container for connected hemispheres" is as shown in FIG. 4, the inner surface shape of each foamed plastic storage container 22c for connected semi-circular spheres is not limited to the shape shown in FIG. 4(B), and a configuration can also be implemented in which each foamed plastic storage container 22c for connected semi-circular spheres has an inner surface shape of "comprising a flat surface portion of the storage container and a side wall portion surrounding the flat surface of the storage container formed around the flat surface portion of the storage container," as shown in FIG. 4(B), and in cross section, "a side wall portion surrounding the flat surface of the storage container formed at an angle of approximately right angles from the flat surface portion of the storage container toward the opening of the foamed plastic storage container." In addition, a configuration can be implemented in which the planar shape includes a pentagonal plastic storage container 22c for connected semi-circular spheres, as shown in Figure 4(Ba), or a circular, elliptical, triangular, rectangular, hexagonal, heptagonal, or other polygonal shape.

[0245] When the cooling / heating device 1 is worn covering the surface of the affected part of the human body, the side of the connecting hemisphere foam plastic container opening 22e of the connecting hemisphere foam plastic container 22c covers the surface of the affected part of the human body, so that the affected part of the human body can be cooled or heated.

[0246] Preferably, each of the connected semi-spherical foam plastic containers 22c has a shape that is approximately trapezoidal in cross section.

[0247] Preferably, the inner surface shape of each foamed plastic storage container 22c for connected hemispheres has a shape that is approximately trapezoidal in cross section, and is composed of a flat surface portion 22a of the storage container for heads of connected hemispheres and a side wall portion 22b surrounding the flat surface of the storage container for heads of connected hemispheres, which is formed at an angle that widens from the flat surface portion 22a of the storage container for heads of connected hemispheres toward the opening 22e of the storage container for heads of connected hemispheres made of foamed plastic.

[0248] That is, the connected, approximately hemispherical, hollow foam plastic molding material 22 serving as the surface member has the form of a plurality of connected, approximately hemispherical, hollow foam plastic storage containers 22d formed by connecting together a plurality of connected, hemispherical, foam plastic storage containers 22c, and the inner shape of each connected, hemispherical, foam plastic storage container 22c comprises a flat surface portion 22a of the connected, hemispherical, head storage container and a side wall portion 22b surrounding the flat surface of the connected, hemispherical, head storage container which is formed at an angle that widens from the flat surface portion 22a of the connected, hemispherical, head storage container toward the opening 22e of the connected, hemispherical, foam plastic storage container.

[0249] As shown in FIG. 14(C), the cooling / heating medium 3 as shown in FIG. 14(Bc) is placed in each of the connected semi-spherical foam plastic containers 22c. When the cooling / heating device 1 is worn covering the surface of the human head, the side of the connecting hemisphere foam plastic container opening 22e of the connecting hemisphere foam plastic container 22c covers the surface of the human head, so that the human head can be cooled or heated. In this case, the shape-retaining container 32c can preferably be a shape-retaining container 32c having an outer shape formed by a flat surface portion 22a of the container for heads of connected hemispheres that roughly matches the inner shape of each foam plastic container for heads of connected hemispheres 22c, and a flat surface peripheral side wall portion 22b of the container for heads of connected hemispheres formed around the flat surface portion of the container for heads of connected hemispheres, as shown in Figure 14(Ba) or Figure 17(A).

[0250] This configuration achieves the aforementioned "Configuration Effect 18" and "Configuration Effect 18-i," and also achieves [Configuration Effect 19: "It is possible to form foam plastic storage containers 22c for connected hemispheres that have the largest possible area ratio to the total area of ​​the surface member, and a cooling or heating medium can be placed in each foam plastic storage container 22c for connected hemispheres, thereby minimizing the area where a cooling or heating medium is not placed, resulting in a cooling or heating device 1 that can efficiently cool or heat the entire human head, and furthermore, the cooling or heating medium can be easily placed, installed, and / or removed from each foam plastic storage container 22c for connected hemispheres without the need for skill, resulting in a cooling or heating device 1 that is easy to handle."

[0251] The angle at which the flat surface portion 22a of the container for heads of connected hemispheres and the side wall portion 22b around the flat surface of the container for heads of connected hemispheres, which is formed at an angle extending from the flat surface portion 22a of the container for heads of connected hemispheres toward the opening 22e of the container for heads made of foam plastic for connected hemispheres, is configured is not particularly limited, but for example, an angle exceeding 90 degrees is preferable, and an angle in the range of 91 degrees to 160 degrees is even more preferable, and an angle in the range of 95 degrees to 150 degrees is even more preferable. If the angle of expansion is less than 90 degrees, difficulties tend to arise when storing and / or removing the cooling / heating medium in each of the connected semi-spherical foam plastic storage containers 22c.

[0252] [Subordinate Structure 20] The cooling / heating devices 1 of the above-mentioned "subordinate configuration 17" to "subordinate configuration 19" preferably have the following configurations. "The connected, approximately hemispherical, hollow foam plastic molding material 22 has the form of a plurality of connected, approximately hemispherical, hollow foam plastic storage containers 22d formed by connecting a plurality of connected, approximately hemispherical, hollow foam plastic storage containers 22c together, and the inner surface shape of each of the connected, approximately hemispherical, hollow foam plastic storage containers 22c has a connected, hemispherical, head-containing, flat surface portion 22a and a connected, hemispherical, head-containing, flat surface peripheral side wall portion 22b formed around the connected, hemispherical, head-containing, flat surface portion, and has the form of a storage container having a connected, hemispherical, head-containing, foam plastic storage container opening 22e.

[0253] For example, each of the plurality of foam plastic storage containers 22c for connected hemispheres may have a shape similar to that of a foam plastic storage container having a shape similar to that of a storage container that has a substantially circular, elliptical, polygonal, etc. planar shape, a semicircular, rectangular, square, trapezoid, etc. cross-sectional shape, and a foam plastic storage container opening with a recessed depression, as shown in (A), (B), (C), (D), and (E) of Figures 4A, 4B, 4C, 4D, and 4E, and has a shape similar to that of a storage container having a foam plastic storage container opening with a recessed depression, and two of these foam plastic storage containers 22c for connected hemispheres have such shapes and are connected to form a three-dimensional shape with a predetermined substantially hollow hemisphere in appearance.

[0254] For example, it is possible to combine connected semi-spherical foamed plastic storage containers 22c having different shapes, such as a combination of a pentagon and a hexagon, or a combination of a triangle and a pentagon, or a combination of a circle and a hexagon, or a combination of a circle and an ellipse, to form a connected approximately semi-spherical hollow foamed plastic molding material (22) into a three-dimensional shape with a predetermined approximately semi-spherical hollow shape in appearance.

[0255] FIG. 16 is a schematic diagram illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention. Figure 16 is a schematic cross-sectional view showing the general shape of the cross section of a cooling / heating device 1 that is formed so that the affected part of the human body is the human head and can cool or heat the human head, Figure 16(A) is a schematic cross-sectional view of the cooling / heating device 1, and Figure 16(B) is a schematic side view of the cooling / heating medium 3. As shown in Figure 16(B), each of the multiple foamed plastic storage containers 22c for connected hemispheres has the shape of a circular and / or polygonal container that is at least approximately circular, approximately elliptical, or approximately polygonal in plan view, and the connected approximately hemispherical hollow foamed plastic molding material 22 has a quasi-polyhedral surface shape formed in a form that includes a combination of at least two or more types of foamed plastic storage containers 22c for connected hemispheres, and is formed into an approximately hemispherical hollow shape. As shown in FIG. 16(A), the cooling / heating medium 3 is placed in each of the connected semi-spherical foam plastic containers 22c.

[0256] In Figure 16, the inner surface shape of each of the multiple foam plastic storage containers 22c for connected hemispheres is formed by a flat surface portion 22a of the container for heads of connected hemispheres and a flat surface surrounding side wall portion 22b of the container for heads of connected hemispheres formed around the flat surface portion of the container for heads of connected hemispheres, and a cooling / heating medium 3 is placed in each foam plastic storage container 22c for connected hemispheres.

[0257] 16, each of the plurality of foam plastic containers 22c for connected hemispheres is configured by combining a foam plastic container 22c for connected hemispheres having an inner surface formed from a pentagonal flat surface 22a for the heads of the connected hemispheres and a peripheral side wall 22b formed at an angle of approximately 90 degrees from the periphery of the pentagonal flat surface 22a for the heads of the connected hemispheres, with a foam plastic container 22c for connected hemispheres having an inner surface formed from a hexagonal flat surface 22a for the heads of the connected hemispheres and a peripheral side wall 22b formed at an angle of approximately 90 degrees from the periphery of the hexagonal flat surface 22a for the heads of the connected hemispheres. That is, each foam plastic container 22c for connected hemispheres has a substantially rectangular cross-sectional shape.

[0258] The cooling and heating medium 3 can be a shape-retaining sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in the "subordinate configuration 23" below, is contained in a sealed container (32), or a flexible sealed cooling and heating medium 3 in which a cooling and heating agent 31, described in the "subordinate configuration 24" below, is contained in a sealed container 32.

[0259] In the present invention, the "connected hemisphere foam plastic storage container 22c having an inner surface shape formed by the flat surface portion 22a of the connected hemisphere head storage container having a pentagonal shape and the side wall portion 22b surrounding the flat surface of the connected hemisphere head storage container formed at an angle of approximately 90 degrees" shown in FIG. 16 is combined with the "connected hemisphere foam plastic storage container 22c having an inner surface shape formed by the flat surface portion 22b surrounding the flat surface of the connected hemisphere head storage container formed at an angle of approximately 90 degrees" shown in FIG. An example is shown in which the container is formed into a shape, but the configuration is not limited to this. A surface member can be formed into an approximately hollow hemispherical shape overall by combining a foamed plastic container for connected hemispheres 22c having a desired shape, such as a circular and / or polygonal container, in which the flat surface portion 22a of the container for connected hemisphere heads has a desired approximately circular, elliptical, polygonal, etc. shape and the flat surface peripheral side wall portion 22b of the container for connected hemisphere heads is formed at a desired inclination angle from the periphery of the flat surface portion 22a of the container for connected hemisphere heads.

[0261] For example, a surface member can be produced by combining a plurality of foam plastic storage containers 22c for connected hemispheres, each of which has a flat surface portion 22a of the foam plastic storage container for connected hemispheres heads that is a desired polygon such as an approximately triangular, approximately quadrangular, approximately pentagonal, approximately hexagonal, approximately heptagonal, or approximately octagonal, and has a peripheral side wall portion 22b for the flat surface of the storage container for connected hemispheres heads that is formed at a desired inclination angle from the periphery of the flat surface portion 22a of the storage container for connected hemispheres heads. In this case, it is possible to implement a cooling / heating device 1 in which each of the multiple foam plastic storage containers 22c for connected hemispheres has the same shape, or in which each of the foam plastic storage containers 22c for connected hemispheres has two different types of foam plastic storage containers 22c for connected hemispheres, or in which each of the foam plastic storage containers 22c for connected hemispheres has three or more different types of foam plastic storage containers 22c for connected hemispheres.

[0264] As the side wall portion 22b around the flat surface of the container for storing heads for connected hemispheres formed around the flat surface portion 22a of the container for storing heads for connected hemispheres, for example, (a) a side wall portion 22b around the flat surface of the container for storing heads for connected hemispheres formed around the flat surface portion 22a of the container for storing heads for connected hemispheres perpendicularly at an angle of approximately 90 degrees to the flat surface portion 22a of the container for storing heads for connected hemispheres, or (a) a side wall portion 22b around the flat surface of the container for storing heads for connected hemispheres formed at an angle that widens from the periphery of the flat surface portion 22a of the container for storing heads for connected hemispheres toward the opening (22e) of the container for storing heads made of foam plastic for connected hemispheres, can be preferably implemented.

[0265] This configuration provides the cooling / heating device 1 that can more effectively exhibit the aforementioned "Configuration Effect 17" to "Configuration Effect 19." [Configuration Effect 21]

[0266] For example, as shown in Figure 16, each foamed plastic storage container 22c for connected hemispheres has a configuration in which at least a pentagonal container and a hexagonal container are combined to form an approximately hollow hemisphere, and a cooling / heating device 1 can be preferably implemented in which a cooling / heating medium 3 can be placed inside each foamed plastic storage container 22c for connected hemispheres.

[0267] Figure 17 is a schematic diagram illustrating the configuration of a cooling / heating device 1 according to one embodiment of the present invention, where Figure 17(A) is a schematic cross-sectional view of the cooling / heating device 1, and Figure 17(B) is a schematic plan view of the cooling / heating medium 3 as viewed from above. For example, as shown in Figure 17, each foamed plastic storage container 22c for connected hemispheres has a configuration in which at least a pentagonal container and a hexagonal container are combined to form an approximately hollow hemisphere, and a cooling / heating device 1 can be preferably implemented in which a cooling / heating medium 3 can be placed in each foamed plastic storage container 22c for connected hemispheres.

[0268] In Figures 16 and 17, each of the multiple foamed plastic storage containers 22c for connected hemispheres has a flat surface portion 22a of the container for heads of connected hemispheres and a flat surface surrounding side wall portion 22b formed around the flat surface portion of the container for heads of connected hemispheres, and also has a foamed plastic storage container opening 22e for connected hemispheres.

[0269] Since each foamed plastic storage container 22c for the connected hemispheres is formed by combining a pentagonal storage container and a hexagonal storage container, it is possible to form foamed plastic storage containers 22c for the connected hemispheres that have a large area ratio to the total area of ​​the surface member, and it is possible to place a cooling or heating medium in each foamed plastic storage container 22c for the connected hemispheres, resulting in a cooling or heating device 1 that can cool or heat the entire head with little space between them.

[0270] This configuration not only achieves the aforementioned "Configuration Effect 17" to "Configuration Effect 19," but also provides [Configuration Effect 21-B: A cooling / heating device 1 that can more effectively achieve the aforementioned "Configuration Effect 18." In particular, the cooling / heating device 1, which is configured to have an approximately hemispherical hollow shape formed by combining at least a plurality of pentagonal connected hemispherical foam plastic storage containers 22c and hexagonal connected hemispherical foam plastic storage containers 22c, can minimize the area where a cooling / heating agent is not placed, and further achieves the effect of being able to efficiently form the connected approximately hemispherical hollow hemispherical foam plastic molding material 22, and having a form that can firmly maintain the approximately hemispherical hollow shape without deformation].

[0271] [Subordinate Structure 22] The cooling / heating device 1 of the above-mentioned "subordinate configuration 17 to subordinate configuration 21" preferably has the following configuration. The surface member 2 has a form that can be worn to cover the human head, and at least has the form of a connected, approximately hemispherical hollow foamed plastic molding material 22 in which foamed plastic material 20 is formed into an approximately hemispherical hollow shape, and the connected, approximately hemispherical hollow foamed plastic molding material 22 has a form that has shape retention that allows it to maintain the approximately hemispherical hollow shape. The surface member 2 is (a) capable of being worn by extending and stretching in the circumferential direction of the connected substantially hemispherical hollow foam plastic molding material 22 having a substantially hemispherical hollow shape and / or in the diametric direction of the connected substantially hemispherical hollow foam plastic molding material 22 and / or in the direction from the center of the connected substantially hemispherical hollow foam plastic molding material 22 to the opening 22e of the connected semispherical foam plastic storage container, when worn by covering the human head, and is formed so as to be able to contract to its original shape when worn by covering the human head, and / or (b) capable of being worn by extending and stretching in the circumferential direction of the connected substantially hemispherical hollow foam plastic molding material 22 having a substantially hemispherical hollow shape and / or in the diametric direction of the connected substantially hemispherical hollow foam plastic molding material 22 and / or in the direction from the center of the connected substantially hemispherical hollow foam plastic molding material 22 to the opening 22e of the connected semispherical foam plastic storage container, when worn by covering the human head, and is formed so as to be able to contract to its original shape when worn by covering the human head, and / or The connected, approximately hemispherical, hollow foam plastic molding material 22 can be worn by extending and stretching in the circumferential direction of the plastic molding material 22, and / or in the diameter direction of the connected, approximately hemispherical, hollow foam plastic molding material 22, and / or in the direction from the center of the connected, approximately hemispherical, hollow foam plastic molding material 22 to the opening 22e of the connected hemispherical foam plastic storage container, and is formed so that it can contract to its original shape when worn to cover the human head, and when worn to cover the human head, the connected, approximately hemispherical, hollow foam plastic molding material 22 is compressed and / or stretched in the direction of the surface of the human head, so as to adhere to and / or come into contact with the surface of the human head, thereby suppressing cold air or warm air from escaping in the outward direction of the surface member 3.

[0272] In the case of the above configuration (B), in which the cooling / heating medium 3 has a shape-retaining container sealing cover 32e, a preferable configuration is that the shape-retaining container sealing cover 32e is located on the inner periphery of the outer periphery of each of the flat surface peripheral side walls 22b of the head-receiving container for the connecting hemispheres, and the edge of the outer periphery on the opening side of the flat surface peripheral side walls 20b of the container is exposed when the cooling / heating medium 3 is placed inside the surface member 2. This configuration prevents cold air from escaping outward from the surface member 3, and the cooling / heating medium 3 can efficiently cool the human head.

[0273] In the above-mentioned subordinate configuration 22, a configuration can be preferably implemented in which "the surface member 2, at room temperature, can be bent at an angle of 90 degrees without breaking when force is applied, and has flexibility to return to its original angle when the force is removed, and when the surface member 2 is worn to cover the human head, it can be worn by extending and stretching in the circumferential direction of the connected approximately hemispherical hollow foamed plastic molding material 22 having an approximately hemispherical hollow shape, and / or in the diametric direction of the connected approximately hemispherical hollow foamed plastic molding material 22, and / or in the direction from the center of the connected approximately hemispherical hollow foamed plastic molding material 22 to the opening 22e of the foamed plastic storage container for the connected hemisphere, and is formed so that it can be contracted to its original shape when worn to cover the human head."

[0274] In the configuration of the above-mentioned subordinate structure 22, preferably, when the surface member 2 is worn over the human head, it is stretchable by a length of at least about 3%, preferably at least about 5%, and more preferably at least about 10% in the circumferential direction of the connected approximately hemispherical hollow foamed plastic molding material 22 having an approximately hemispherical hollow shape, and / or in the diametric direction of the connected approximately hemispherical hollow foamed plastic molding material 22, and / or in the direction from the center of the connected approximately hemispherical hollow foamed plastic molding material 22 to the opening 22e of the foamed plastic storage container for the connected hemispheres, and is formed so as to be able to contract to its original shape when worn over the human head. For example, in the case of a cooling / heating device in which the length in the peripheral direction of the connected, approximately hemispherical hollow foam plastic molded material 22 is approximately 60 cm, it is preferable that the connected, approximately hemispherical hollow foam plastic molded material 22 be extendable to a length of approximately 18 mm or more in the peripheral direction and be able to contract to its original length when worn to cover the human head. Also, it is preferable that the surface member 2 contracts in a direction that compresses the human head when it contracts to its original length.

[0275] It should be noted that the "circumferential direction of the connected approximately hemispherical hollow foamed plastic molding material 22 having an approximately hemispherical hollow shape and / or the diametric direction of the connected approximately hemispherical hollow foamed plastic molding material 22 means the circumferential direction passing through the forehead, temporal region and occipital region of the human head when the cooling / heating device is attached to the human head. "The direction from the center of the connected, approximately hemispherical, hollow foam plastic molding material 22 to the opening 22e of the connected hemispherical foam plastic storage container" means the direction from the top of the head to the forehead, ears, and back of the head when the cooling / heating device is attached to the head. In the above configuration, the surface member 2 is preferably formed so that it can be worn over the human head and / or can be worn over the human head without breaking and / or being damaged. Preferably, the surface member 2 is a foamed plastic material 20 that has the property of expanding without breaking or damaging when force is applied, and contracting to its original length without breaking or damaging when the force is removed.

[0276] As the foamed plastic material 20 constituting the surface member 2 that is extensible, contractible, and flexible, at least one foamed plastic material 20 selected from the group consisting of foamed polyolefin resin, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer obtained by copolymerizing ethylene monomer with other vinyl monomer, foamed polyvinyl acetate, foamed natural rubber, foamed nitrile rubber, foamed nitrile-butadiene rubber, foamed chloroprene rubber, foamed silicone rubber, foamed ethylene-propylene rubber, foamed polyvinyl chloride, foamed polyvinyl alcohol, foamed polypropylene, foamed polyurethane, foamed polyacrylic, foamed ethylene propylene diene rubber, and foamed ester-based elastomer, as will be described in the "subordinate configuration 29" below, can be preferably implemented. As the foamed plastic material 20 constituting the surface member 2, which is stretchable, contractible and flexible, foamed polyethylene, foamed ethylene-vinyl acetate copolymer, foamed polyethylene copolymer copolymerized with ethylene monomer and other vinyl monomer, or foamed polyvinyl acetate are particularly preferred.

[0277] This configuration achieves the aforementioned "Configuration Effect 11," "Configuration Effect 17" to "Configuration Effect 21," and also achieves the effect of preventing the cooling / heating device 1 from falling off the head, as follows: [Configuration Effect 22: The connected, approximately hemispherical, hollow foamed plastic molding material 22 is formed to be stretchable and contractible in the circumferential direction of the opening of the approximately hemispherical hollow shape and / or in the planar direction of the approximately hemispherical hollow shape, so that when it is attached to the human head, the opening of the cooling / heating device 1 can be easily attached in a stretched and widened state, and when the force is released after it has been attached to the human head, the opening of the cooling / heating device 1 shrinks to its original length, thereby preventing the cooling / heating device 1 from falling off the human head. Furthermore, in particular, by covering the human head and attaching it by stretching it in the surface direction from the opening of the approximately hemispherical hollow shape to the center, the connected approximately hemispherical hollow foam plastic molding material 22 contracts in the direction of compressing the human head via the cooling and heating medium 3, the cooling and heating medium 3 is compressed toward the human head, and the surface member 2 adheres to and / or comes into contact with the surface of the human head, thereby suppressing the cold or warm air from escaping in the outward direction of the surface member (3), and the human head is efficiently cooled or heated by the cooling and heating medium 3.

[0278] [Subordinate Structure 23] The cooling / heating device 1 of the above-mentioned "subordinate configuration 17 to subordinate configuration 22" preferably has the following configuration.

(b-c) The sealed container 32 has a shape-retaining container 32c which has a hemispherical three-dimensional shape having an approximately semicircular cross-section and has enough shape retention to maintain the shape formed at an angle that widens from the top of the hemispherical three-dimensional shape toward the opening, a shape-retaining container flange portion 32d formed around the opening of the shape-retaining container 32c, and a shape-retaining container sealing cover 32e which covers the opening of the shape-retaining container 32c and is joined to the shape-retaining container flange portion 32d to be able to seal. (b-d) The sealed container 32 has a shape-retaining container 32c having enough shape retention to maintain the shape formed therein, which has a shape-retaining container flat surface portion 32a and a shape-retaining container side wall portion 32b formed at an angle of approximately 90 degrees from the shape-retaining container flat surface portion 32a toward the opening, a shape-retaining container flange portion 32d formed around the opening of the shape-retaining container 32c, and a shape-retaining container sealing cover 32e that covers the opening of the shape-retaining container 32c and is joined to the shape-retaining container flange portion 32d to be able to seal. The outer surface shape of the shape-retaining container 32c roughly matches the inner surface shape of each of the foamed plastic storage containers 22c for the connected hemispheres, and the cooling / heating medium 3 is placed in each of the foamed plastic storage containers 22c for the connected hemispheres.

[0280] Preferably, the outer surface shape of the shape-retaining container 32c has a shape that roughly matches the inner surface shape of each of the connected semi-spherical foam plastic containers 22c. For example, if each foamed plastic storage container 22c for connected hemispheres has the shape of a foamed plastic storage container as described above in Figure 4, the outer shape of the shape-retaining container 32c has a shape that roughly corresponds to the inner shape of the foamed plastic storage container as described above in Figure 4. The cooling and heating agent 31 is stored in the shape-retaining container 32c, and each cooling and heating medium 3, which is sealed with a shape-retaining container sealing cover 32e, is placed in each of the connected semi-spherical foam plastic storage containers 22c.

[0281] In this configuration, the cooling / heating medium 3 is preferably configured to be able to be stored in and / or removed from each of the connected semi-spherical foam plastic storage containers 22c. Preferably, the cooling / heating medium 3 is configured so that it can be installed in a shape that roughly matches the shape of the inner surface side of the surface member 2 when cooled / heated to a desired temperature.

[0282] This configuration achieves the aforementioned "Configuration Effect 11," "Configuration Effect 17," and "Configuration Effect 22," as well as "Configuration Effect 23: The area of ​​contact with the human head can be maximized, making it possible to efficiently cool or heat the entire human head. Also, a cooling / heating device 1 for cooling or heating the human head can be obtained, which has the effect of being usable by repeating the cycle of storing cooled or heated cooling / heating medium 3 in each foam plastic storage container 20c, attaching it to the human head, and then removing the cooling / heating medium 3 from the foam plastic storage container 20c after a predetermined time has passed, and cooling or heating the removed cooling / heating medium 3.

[0283] The shape-retaining container 32c, which has enough shape-retaining properties to maintain its shape, is not particularly limited, but may be, for example, polyethylene, polypropylene, polystyrene, polyethylene terephthalate (generic name: polyester), polyamide (generic name: nylon), or other general-purpose plastic containers, preferably with a thickness of 0.1 to 2 mm, and more preferably with a thickness of 0.2 to 1 mm. Shape-retaining containers 32c having enough shape-retaining properties to maintain such a shape can be easily mass-produced by, for example, vacuum molding, injection molding, compression molding, or other general-purpose molding methods.

[0284] The schematic diagrams for explaining the configuration of the cooling / heating device 1 according to one embodiment of the present invention are shown in the aforementioned FIGS. As shown in Figures 13(A) and 14(A), the surface member 2 has a form that can be worn to cover the human head, and has the form of at least a connected approximately hemispherical hollow foamed plastic molding material 22 formed by forming a foamed plastic material 20 into an approximately hemispherical hollow shape. The connected, approximately hemispherical, hollow foam plastic molding material 22 is formed into a shape that has shape-retaining properties that allow it to maintain its approximately hemispherical hollow shape. The connected, approximately hemispherical, hollow foam plastic molding material 22 has the form of a plurality of connected, approximately hemispherical, hollow foam plastic storage containers 22d, which are formed by connecting together a plurality of connected hemispherical foam plastic storage containers 22c. Each of the multiple foamed plastic storage containers 22c for connected hemispheres has a flat surface portion 22a for the heads of the connected hemispheres and a flat surface peripheral side wall portion 22b for the heads of the connected hemispheres formed around the flat surface portion of the container for connected hemispheres, and has the shape of a storage container with an opening 22e for the foamed plastic storage container for connected hemispheres.

[0285] As shown in Figures 13(Ba), (Bb), (Bc) and Figures 14(Ba), (Bb), (Bc), each sealed container 32 comprises a shape-retaining container 32c having enough shape-retaining ability to maintain its shape, and a shape-retaining container sealing cover 32e formed to cover the opening of the shape-retaining container 32c and be able to seal it. The shape-retaining container 32c has a shape-retaining container flat surface portion 32a and a shape-retaining container side wall portion 32b formed in the peripheral region of the shape-retaining container flat surface portion 32a. The cooling / heating agent 31 is contained or accommodated in the shape-retaining container 32c. That is, the cooling / heating medium 3 has a cooling / heating agent 31 contained in a sealed container 32 comprising a shape-retaining container 32c having enough shape retention to maintain its shape and a shape-retaining container sealing cover 32e formed to cover the opening of the shape-retaining container 32c and be able to seal.

Also, as shown in Figures 13(Ba), (Bb), 14(Ba), (Bb), the sealed containers 32 are configured to be able to be stored and / or removed from each of the foamed plastic storage containers 22c for the connected hemispheres.

[0288] As shown in Figures 13(Bc) and 14(Bc), the shape-retaining container sealing cover 32e covers the opening of the shape-retaining container 32c, and the shape-retaining container sealing cover 32e is joined and sealed around the end face of the flat surface peripheral side wall portion 20b. The shape-retaining container sealing cover 32e is not particularly limited, and may be made of a material that is flexible enough to be bent, or a material that is not bendable.

The thickness of these conventional plastic films or laminated films is not particularly limited, but for example, a thickness of about 0.003 mm to about 1 mm, which is flexible enough to allow deformation, is preferably used.

[0289] [Subordinate Structure 24] The cooling / heating device 1 of the above-mentioned "subordinate configuration 17 to subordinate configuration 22" preferably has the following configuration. [The cooling / heating medium 3 is configured in the form of a sealed cooling / heating medium in which a cooling / heating agent 31 is accommodated in a sealed container 32, and the sealed container 32 has flexibility to the extent that it can be bent].

[0290] Preferably, the cooling / heating medium 3 has flexibility to the extent that it can be deformed, and has a shape that can be deformed to roughly match the inner shape of each of the connected semi-spherical foam plastic containers 22c.

Preferably, the cooling / heating medium sealing cover member 4 is further provided, and the cooling / heating medium sealing cover member 4 has a shape that covers the opening 22e of the foam plastic storage container for the connected hemispheres of each foam plastic storage container 22c for the connected hemispheres that contains the cooling / heating medium 3, and also seals the end face of the flat surface surrounding side wall portion 22b of the storage container for the head of the connected hemispheres. It should be noted that a configuration in which such a cooling / heating medium sealing cover member 4 is not provided is also possible.

[0292] The above configuration provides the aforementioned "Configuration Effect 11," "Configuration Effect 17" to "Configuration Effect 22," and also provides the effect of "Configuration Effect 24: The configuration in which the cooling / heating agent is contained in a flexible plastic film container makes it easy to design and manufacture the flexible plastic film container in a desired shape, making it possible to design a sealed cooling / heating medium in a desired shape that can cover a desired area of ​​the human head and cool or heat the desired area, thereby making it possible to efficiently cool or heat the desired area of ​​the human head. In addition to achieving the aforementioned "Construction Effect 11," "Construction Effect 17," and "Construction Effect 22," the cooling / heating device 1 for cooling or heating the human head can be obtained, which has the following effect: [Construction Effect 24-A: By configuring the cooling / heating agent to be contained in a flexible plastic film container, the shape of the flexible plastic film container can be easily designed and manufactured to match the inner shape of the approximately hemispherical hollow foam plastic molding material 21, thereby maximizing the area that comes into contact with the human head and efficiently cooling or heating the entire human head.] Furthermore, the cooling / heating device 1 for cooling or heating the human head can be obtained, which can be used by repeatedly storing the cooled or heated sealed cooling / heating medium 3 in each foam plastic storage container 20c, attaching it to the human head, removing the sealed cooling / heating medium 3 from the foam plastic storage container 20c after a predetermined time has passed, and cooling or heating the removed sealed cooling / heating medium 3.

[0293] For example, as shown in Figures 16(A) and (B) above, the cooling / heating medium 3 can be configured in the form of a sealed cooling / heating medium 3 in which a cooling / heating agent 31 is contained in a sealed container 32, and the sealed cooling / heating medium 3 can be deformed into a shape that matches the inner shape of an approximately hemispherical hollow foam plastic molding material 21 and installed. For example, as shown in Figures 16(A) and (B) above, a cooling / heating medium sealing cover member 4 is provided, and the cooling / heating medium sealing cover member 4 has a shape that covers the opening 22e of the foam plastic storage container for the connected hemispheres of each foam plastic storage container 22c for the connected hemispheres that contains the cooling / heating medium 3, and also seals the end face of the flat surface surrounding side wall portion 22b of the storage container for the head of the connected hemispheres.

[0294] In this configuration, the sealed container 32 may be a single sealed container or a sealed container divided into multiple pieces, and it is also possible to implement a configuration in which each sealed container 32 contains a cooling / heating agent 31 in a sealed state.

For example, a flexible plastic laminated film bag-shaped container can be used, which has an inner layer made of heat-sealable polyethylene or polypropylene and an outer layer made of polyamide (nylon) or polyester (polyethylene terephthalate) that has high mechanical strength. Without being limited to this, a plastic laminated film bag-shaped container using polyvinyl chloride, aluminum vapor deposition film, etc. can also be used. The inner polyethylene layer or the inner polypropylene layer is heat-sealable, and film bag containers of any shape can be sealed by heat-sealing.

In this way, the cooling / heating medium 3 can be used repeatedly.

[0299] 16, for example, the sealed cooling / heating medium 3, which is a cooling / heating agent 31 contained in a sealed container 32, is placed in each of the connected semi-spherical foam plastic containers 22c in a cooled or heated state, and the cooling / heating device 1 is then worn on the head for use. After a predetermined time, the cooling / heating device 1 is removed from the head, and the cooling / heating medium 3 is taken out of each of the connected semi-spherical foam plastic containers 22c, allowing the taken-out cooling / heating medium 3 to be used for cooling or heating. In this way, the cooling / heating medium 3 can be used repeatedly.

[0300] The above configuration provides a cooling / heating device 1 that achieves the following effects: [The aforementioned "Configuration Effect 17" to "Configuration Effect 22," "Configuration Effect 23," and "Configuration Effect 24" are obtained, and since the cooling / heating medium 3 can be reused repeatedly, the cooling / heating medium 3 can be used economically and inexpensively without being discarded. Also, the cooling / heating medium 3 can be placed in a desired one of the multiple connected hemispherical foam plastic storage containers 22c, which makes it possible to cool or heat a desired area of ​​the human head, thereby providing an optimal cooling or warming sensation.]

A thermally conductive insulating material that has the function of suppressing heat conduction, and is at least one of (a) a foamed plastic material, (b) a thermally insulating nonwoven fabric material, and (c) a laminated nonwoven fabric material formed by laminating multiple nonwoven fabrics. A metal film radiation insulation material that functions to block heat by radiation from at least one of the following materials: (d) a metal foil material; (e) a metal thin film material formed by metal vapor deposition; and (f) a metal thin film material with a substrate, in which a metal thin film is attached to a plastic film substrate, a sheet-like nonwoven fabric substrate, or a sheet-like fabric substrate.

[0306] This configuration provides the aforementioned "Configuration Effect 11 to Configuration Effect 24," as well as [Configuration Effect 25-i: when the sheet-shaped heat transfer suppressing head-side inner surface member 81 is worn over the human head, it becomes possible to transfer the cold air or heat of the cooling / heating medium 3 to the human head in the desired cold air or heat state, thereby significantly improving the cooling / heating effect of cooling or heating the human head in the desired comfortable state], and in particular, when the cooling / heating device 1 is worn on the human head, it prevents the cooling / heating medium 3 from coming into direct contact with the scalp, and adjusts the cold air or heat that reaches the surface of the human head from the cooling / heating medium 3 to the desired temperature, thereby suppressing the wearer's discomfort from being too cold or too hot, and making it possible to adjust the temperature to a comfortable level].

[0307] As the above-mentioned (a) heat insulating foamed plastic material, a microporous foamed plastic material containing a large number of microbubbles can be preferably used. The microporous bubble-containing foamed plastic material is preferably a microporous bubble-containing foamed plastic material having a large number of microporous bubbles, each of which has a size of 0.5 mm or less. Flexible foamed plastic materials are also particularly suitable, which, when worn on the human head, allow the material to deform to conform to the shape of the head and, further, provide a comfortable fit without a stiff feeling on the head. Examples of microporous bubble-containing foamed plastic materials and flexible foamed plastic materials that can be used include soft polyurethane foam with open cells containing microporous bubbles, foamed silicone rubber, and soft polyethylene-based foams made from copolymers of polyethylene and other monomers.

[0308] (b) The insulating nonwoven fabric material is a nonwoven fabric material formed by bonding short fibers such as polyester staple fibers, polyamide (nylon) staple fibers, polyolefin staple fibers, acrylic staple fibers, cotton, wool, felt, and other staple fibers into a cotton-like form and forming it into a sheet, and any insulating nonwoven fabric material of the desired configuration having the desired porosity, bulk density, thickness, basis weight, etc. can be used.

[0309] "Metal film radiant heat insulating material" is a heat insulating material that functions to block heat by radiation. As the metal film radiant heat insulating material (d), for example, aluminum foil or other metal foils can be used. The thickness of these metal film radiant heat insulating materials is not particularly limited, but is preferably about 1 to 100 μm. (e) Examples of metal thin film materials formed by metal vapor deposition include aluminum vapor deposition thin films formed by vapor deposition of aluminum, and metal vapor deposition thin films formed by vapor deposition of other metals. The thickness of these metal film radiant heat insulating materials is not particularly limited, but an ultra-thin film of, for example, less than about 1 μm is preferred. (f) Examples of the metal thin film material with a substrate that can be used include an aluminum thin film-attached nonwoven fabric in which an aluminum thin film is attached to a thin cloth-like nonwoven fabric sheet, an aluminum thin film-attached plastic sheet in which an aluminum thin film is attached to a thin plastic sheet, an aluminum thin film-attached woven fabric in which an aluminum thin film is attached to a cloth-like woven fabric, or an aluminum vapor-deposited film material in which an aluminum vapor-deposited film is deposited directly on a substrate as the aluminum thin film. This type of metal film radiation insulation material has good thermal conductivity, which allows it to transfer heat in a planar direction, and the smooth, flat metal sheet has the radiation performance to reflect heat. Therefore, a sheet made of metal film radiation insulation material has the effect of suppressing variations in the planar direction of the cold or heat generated by the cooling / heating medium by uniformly transferring the cold or heat to the metal surface in a planar direction.

[0310] (b) The gap-forming heat transfer suppressing head-side inner surface member 82, which has the function of suppressing heat transfer by a gap, can be worn to cover the human head when attached to the human head, and is formed so as to suppress cold air or heat from the cooling / heating medium 3 reaching the human head. It is capable of forming a gap with an air layer between the cooling / heating medium 3 and the human head, and has the function of suppressing the transfer of cold air or heat by the gap. The gap-forming heat transfer suppression head-side inner surface member 82 is not particularly limited, but preferably includes, for example, (r) a mesh-shaped plastic molding material formed in a mesh shape, and / or (s) a flexible mesh-shaped plastic molding material that has flexibility and / or elasticity and is formed in a mesh shape, (t) a flexible mesh-shaped plastic foam molding material formed from a plastic foam molding material that has flexibility and / or elasticity and is formed in a mesh shape, and / or (u) a gap-forming nonwoven fabric material formed from nonwoven fabric and having a large number of gaps, and / or (w) a gap-forming fiber material having Russell-shaped and / or double Russell-shaped through holes.

[0311] In the above-mentioned mesh-shaped plastic molding materials (r), (s), and (t), or mesh-shaped thick cloth molding materials (v), or breathable fiber materials such as (w) Russell-shaped materials, the form of the molding materials or forming materials is not particularly limited, but for example, plastic molding materials, mesh-shaped thick cloth molding materials, or breathable fiber materials can be molded into an approximately hemispherical hollow shape with a thickness of 0.1 mm to 10 mm, preferably 0.5 mm to 7 mm, and more preferably 1 mm to 6 mm. The shape of the mesh-shaped through-holes is not particularly limited, but may be, for example, a net-like, lattice-like, mesh-like, Russell-like, double Russell-like, or the like, or a shape having through-holes capable of forming a large number of voids of a desired shape such as a circle, triangle, square, polygon, trapezoid, diamond, or heart. The size of the through-holes is not particularly limited, but, for example, it is preferable that the diameter of one of the mesh-shaped through-holes is approximately 0.5 to 50 mm.

[0312] Generally, when a human body part (e.g., a hand) is inserted into a container containing a low-temperature air atmosphere of approximately 0°C, the hand can be kept in the low-temperature atmosphere for approximately 5 minutes or more, enduring the cold. However, when a human body part (e.g., a hand) comes into contact with the surface of a plastic molding material at a low temperature of approximately 0°C, the cold becomes unbearable and it is difficult to maintain contact with the surface of the plastic molding material for more than approximately 1 minute. Thus, when cold or heat is brought into contact with the head, gaseous cold or heat such as air tends to be able to be tolerated for a longer period of time than solid cold or heat such as molding material, and the cold or heat sensation felt by the head tends to be suppressed. In other words, [Constituent Effect 25-B: The direct transmission of cold or heat from the cooling / heating medium is suppressed, thereby maintaining the cold or heat at the head side at a desired cold temperature that feels comfortable for a long period of time] is achieved.

[0313] The above-mentioned (c) hair pressing stretchable head side inner surface member 83, which has an approximately hemispherical hat shape and functions to press human hair when worn on the human head, is not particularly limited, but for example, it is formed of at least one sheet-like material selected from the group consisting of the following (a) to (o), and is formed so as to be able to press human hair when worn on the human head.
