[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cold-wearing garment mainly including a cold-insulating pad kept at a temperature close to room temperature.

[0002]

[Prior art]

 Conventionally, as a garment for keeping cold, a band to be worn for cooling the head, for example, what is called an Edison band can be mentioned. However, there is nothing specially developed, and in order to relieve bruising and inflammation, plaster coated with a compress is used as a drug, and as a first aid, cold storage in the affected area is used. The material was pressed with a towel.

[0003] A cool-wearing garment for cooling the head is made by laminating a large number of porcelain pieces in a grid pattern on a band that is fastened to the head, and the head is cooled by absorbing body temperature by the porcelain. It was the one

[0004]

[Problems to be solved by the device]

 As described above, the conventional head wearing band as a cold-wearing orthosis has a strong porcelain constituent material, which makes it hard to hit the head and feel uncomfortable. I could not use it comfortably.

When the plaster of poultice is used by being pasted on the affected area, the feeling is not bad, but the components contained in the poultice have a strong odor, and there is a disadvantage that the odor is released to the surroundings. It In addition, the skin is often irritated, causing rash, itch, and rash. On the other hand, when it is a cold storage material, the thermal conductivity is not good, so the cold storage time is long, but once it is left to cool, the cooling ability is lost at all, which is the opposite effect. It

In view of the above-mentioned circumstances, the present invention is a garment for keeping cold, which is always kept at a temperature close to the outside temperature even if it is continuously used for a long time and the body is cooled comfortably. Aimed to provide.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a cold pad in which a flexible bag-like body is filled with a heat transfer fluid and hermetically sealed, and an attaching means for closely holding it on the body. The heat fluid constituted a garment for keeping cold in which fine particles of hard carbon or graphitic carbon having good thermal conductivity were mixed with water.

In the above-mentioned constitution, in order to improve the heat conductivity of the heat transfer fluid, a surfactant is mixed, and in order to prevent the spoilage of water, sodium chloride and a trace amount of a bactericide or a preservative are mixed. There are also things to do.

[Action]

 Hard carbon in a broad sense includes graphite-based carbon (fixed carbon) and hard carbon, and it is known that both show extremely high thermal conductivity. This is attributed to the presence of free electrons, which have a higher thermal conductivity than metals. By the way, in a solid, heat is generally transported by carriers (electrons or holes) involved in electrical conduction and propagation of lattice vibrations. The thermal conductivity of hard carbon or graphitic carbon is due to the propagation of lattice vibration that facilitates carrier movement.

When such fine particles of hard carbon or graphitic carbon having high thermal conductivity are mixed with water, they become a water-slurry liquid state (gel state) and retain high thermal conductivity. According to the constructed cool pillow, when it is left at room temperature or immersed in water, it reaches that temperature in a short time.

When the cold storage pillow that is left at room temperature is used as it is, the room temperature is lower than the body temperature (36 ° C.), and the room temperature is normally 25 ° C. even if it is higher, so that it absorbs heat due to its high thermal conductivity. When wearing a garment for keeping cold, the body is cooled gently and rapidly at a temperature close to room temperature. Further, even if the temperature rises due to heat absorption, due to the high heat conductivity as well, the heat is efficiently radiated to the air or the contact object. Therefore, even if it is used for a long time, the body keeps cooling.

Hard carbon or graphitic carbon is also a far infrared ray generator at room temperature. The far-infrared rays generated at room temperature have a wavelength of about 5 to 15 μm, and the far-infrared rays having a wavelength in this range cause resonance / resonance phenomena in the body and have the effect of working blood into a weak alkali.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 3 show an example implemented as a so-called cold eye patch for cooling the eyes, or as a cooling forehead band for cooling the forehead. It consists of a cold insulation pad 1 and a storage band 3 for holding the cold insulation pad 1 to apply it to the eyes and forehead. That is, the storage band 3 is used as an attachment means for closely holding the cold insulation pad 1 on the body. In addition, in a similar configuration, it can be configured to be wrapped around the legs, arms, torso, etc.

The cold insulation pad 1 is configured by filling a bag-shaped body 5 with a heat transfer fluid 7 having a good thermal conductivity and sealing it. The bag-shaped body 5 is made of a nylon film 9 having a good touch on the outside, and a composite film having a strong polyester film 11 laminated on the inside (a vinyl chloride sheet can be effectively used).

Regarding the sealing, the periphery of the heat transfer fluid 7 is heat-welded to form a brim when the heat transfer fluid 7 is filled. In this case, vacuum degassing packaging is performed in order to prevent the heat transfer fluid 7 from being separated from the heat transfer fluid 7 from spoiling and to increase the thermal conductivity.

As the components of the heat transfer fluid 7, those which were blended as follows were used. These are kneaded with a kneader or a mixer. Fixed carbon powder 50 kg Water 35 kg Glycerin 2 kg Sodium chloride 15 kg Sodium hypochlorite 250 cc Sodium dehydroacetate 250 cc

The fixed carbon fine particles have a purity of 99.4%, and the particle size is about 1000 μm to 1 μm, and the average particle size is about 500 μm to 100 μm. The fluidity is obtained by mixing it with water. The fixed carbon is obtained, for example, by molding coke or pitch and heating it up to about 3000 ° C.

Glycerin is used as a surfactant. As a result, the affinity between the components and between the components and the cloth of the bag-shaped body 5 can be obtained, and a phenomenon such as the generation of voids that hinders thermal conductivity can be prevented. As the surfactant, a higher fatty acid nonionic surfactant that is particularly excellent in emulsifying power, dispersing power, lubricating power, etc. and is hygienic is desirable.

Sodium chloride acts as a sterilizing and sterilizing agent. In addition, sodium hypochlorite is used as a bactericide and sodium dehydroacetate is used as a preservative. Since salt is known to promote health (for example, treatment of diabetes) by close contact with it even without direct contact with salt, its effect is expected.

From the results of various experiments, the desirable proportions (% by weight) of each component are as follows. Hard carbon powder 35-60 Water 20-50 Surfactant 2-5 Salt 10-30 Microbicide, preservative Micro amount

When the hard carbon powder is lower than the above range, the desired thermal conductivity cannot be obtained, and when it is high, the desired fluidity cannot be obtained. With water, it is just the opposite of that.

The storage band 3 as an attaching means for closely holding the cold insulation pad 1 on the body holds the cold insulation pad 1 by stretching the inner net 15 from one end to near the other end on the back surface of the face contact portion 13. The storage bag 19 is configured, and an outer net 21 is stretched at the other end so as to cover the mouth of the storage bag 19. Further, a velvet type fastener tape 20 is attached to the back surface of one end, and the fastener tape 20 is fixed to the cloth on the front surface.

When using, the cold insulation pad 1 is put in the storage bag 19. Then, the cold insulation pad 1 hits the skin through the nets 15 and 21 and cools the body.

When the room temperature was 22 ° C., the garment P for keeping cold was left for 1 hour, and when it reached the same temperature, the students used it to cool their forehead. I was able to improve efficiency. The temperature of the cold insulation pillow after 2 hours of continuous use was 29 ° C (room temperature 20 ° C). When immersed in water (10 ° C), it was cooled to 12 ° C, which is close to the temperature, in about 3 minutes.

FIG. 4 shows an example implemented as a supporter, and an inner net 15 and an outer net 21 constituting a storage bag 19 of the cold insulation pad 1 are stretched inside the supporter body 4. In this case, the supporter main body 4 serves as an attachment means that holds the cold insulation pad 1 in close contact with the body.

FIG. 5 shows an example implemented as a shoulder bag, and the cold insulation pad 1 is formed in a substantially ring shape so as to pass through the neck and hang on the shoulder. In other words, in the case of this embodiment, the shape or structure of the cold insulation pad 1 itself constitutes the adherend means 6 which is held in close contact with the body. The front and back of the bag-shaped body 5 are partially heat-welded so that the heat transfer fluid 7 filled in the bag-shaped body 5 is not unevenly distributed due to gravity.

When the cold-wearing garment P is configured as a shoulder bag in this way, it is very effective not only in eliminating stiff shoulders but also in eliminating fatigue after sports such as swimming and rugby. It is also effective in recovering from fatigue when resting in the shade on the beach.

Also, no energy is required for cooling.

2) In addition to the mild cooling of the body, it is very comfortable to use because it may come into contact with the body flexibly, and if the head of the body is cooled, the mind will concentrate and the thinking will increase. In addition, it is possible to relieve the muscle fatigue by applying it to a fatigued area after sports or work, and of course, when it is cooled with water or a refrigerator, it is cooled rapidly, and in addition, fever, headache, toothache, It can respond to unexpected or unplanned situations such as sunsickness, tired eyes, bruises, and sprains.

3) In addition, the effect of far infrared rays due to hard carbon or graphitic carbon is expected. Due to resonance / resonance phenomenon with the wavelength, not only promotion of sleep, but also diseases such as stiff shoulders and headaches. To improve health and promote health.
