Description Heat insulation material for skin application Technical field

TECHNICAL FIELD The present invention relates to a heat insulating material for skin application used for cosmetic or medical (including massage) applications. More specifically, it relates to a thermal insulation material for skin application that is heated using a microwave oven and is directly applied to the face, neck, arms, and feet. Background art

Various cosmetic and medical effects can be obtained by warming the skin of the face, neck, arms, and feet. For example, by warming the skin and improving blood circulation, a mentally and physically relatable effect can be obtained. In addition, it can promote nutrition supply to the skin and restore the freshness and clarity of the skin. It can also open pores and soften keratin, and can easily remove dirt such as sebum and dust that has caught in the pores by inviting them from the deep part of the pores. In addition, old dead skin can be softened and dropped. The effect of slimming and small face can be expected by sweating. Since various beauty effects can be expected in this way, in the field of beauty, especially in the field of aesthetics, keeping the skin warm and moist is an essential process.

On the other hand, it is not easy to keep skin warm effectively in households with no facilities.For example, facial pack materials that can achieve both warming and moisturizing effects have been disclosed. Did not.

Then, an object of the present invention is to develop a skin heat insulating material that can be used by heating it in a household microwave oven.

As a conventional heat insulating material for skin application, for example, in Japanese Patent Application Publication No. There is disclosed a heat treatment pad in which cereals such as oats are stored in a wrapper and heated by using a microwave oven.

Japanese Patent Application Publication No. 1997-225 and Japanese Patent Application Publication No. 9-652 of 1999 disclosed ceramics in a container made of heat-resistant aramid fiber. In addition to disclosing a `` warm-up moxibustion pack '' containing granules, wrapping serpentine rock fragments in flame-retardant fiber cloth such as rayon, and using a microwave oven at about 70 to 100 ° C The prior art discloses that the heat is used as a heat pack and that a rubber water pillow-like heat pack of the type heated by a microwave oven is used.

By the way, assuming a heat insulation material for skin application used for beauty, especially for facial beauty, it is necessary to have a heat-fever that maintains an appropriate temperature for a long period of time, rather than exothermic, and that it is thin, flexible, and easily adapts to the skin. It needs to be. However, the above-disclosed heat insulating material for microwave application to the skin for microwave heating has been focused on exothermicity rather than animal heat, and was not particularly developed for cosmetic use. The configuration was difficult to make it easy to adapt to. Disclosure of the invention

The present invention provides, as a heat insulating material for skin application to be heated and used by irradiation with electromagnetic waves, a conductive material that absorbs electromagnetic waves and generates heat, and at least has a lower thermal conductivity or a larger specific heat capacity than the conductive material. We propose a thermal insulation material for skin application, comprising a heat material and. .

In addition, the present invention provides a heat-insulating material for skin application that is used by heating by electromagnetic wave irradiation, a conductive material that absorbs electromagnetic waves and generates heat, and a heat conductivity of 75 W / (m−K) or less or a specific heat capacity. We propose a heat insulation material for skin application, comprising a heat storage material of 0.46 kj Z (kg. K) or more.

Still further, the present invention provides a heat insulating material for applying to the skin which is heated by irradiation with electromagnetic waves, as a conductive material which absorbs electromagnetic waves and heats up. We propose a heat insulation material for skin application, comprising: a heat storage material containing any of heat, clay, and stone.

Each of the above-mentioned thermal insulation materials for skin application with the above-mentioned structure is composed of a conductive material that absorbs electromagnetic waves (for example, microwaves irradiated by an electronic range) and generates heat, and an animal heat that retains heat and radiates slowly. The conductive material generates heat in response to electromagnetic waves (for example, microwaves radiated in a microwave oven), transfers this heat to the heat storage material, and heats the heat with the heat storage material. Creates and dissipates heat. Therefore, it can be easily heated in a microwave oven or the like, and once heated, the heat retention effect can be maintained for a long time. Therefore, it can be suitably used as a heat insulation material for beauty and medical treatment (including massage). it can.

In any of the above-mentioned thermal insulation materials for skin application, it is preferable that the conductive material and the heat storage material be in contact with each other. In order to make them exist in a contact state, for example, a heat generation layer made of a conductive material and a heat storage layer made of a heat storage material are laminated, or a cloth or a nonwoven fabric made of conductive fibers and a heat storage material are kneaded. Alternatively, a fabric or nonwoven fabric made of heat storage fiber is laminated, or a conductive material and a heat storage material are mixed, or a heat storage material is kneaded into a fiber made of a conductive material to form a fabric or a nonwoven fabric. The conductive material may be kneaded into fibers made of the heat storage material to form a fabric or a nonwoven fabric, or the cloth or nonwoven fabric containing the heat storage material may be coated or impregnated with a liquid or gel conductive material. . By setting the contact state in this way, heat generated by the conductive material can be efficiently transmitted to the heat storage material.

In the present invention, the “conductive material” may be any material that absorbs electromagnetic waves, particularly microwaves (particularly, a frequency of about 2,450 MHz irradiated by a microwave oven) and generates heat. Among them, carbon fiber, metal fiber, fiber mixed with metal or carbon (carbon), fiber (including whiskers) coated on the surface with a conductive layer, water or a substance composed of charged molecules other than water are preferable. Impregnation Or, _c Among them preferably can include any one of the fibers made by attaching electrical conductivity (electrical conductivity) 1 0 - 6S cm or more fibers can ani gel. From such fibers, a thin, lightweight, and flexible fabric (woven fabric) can be formed into a nonwoven fabric, and a thin, flexible, and heat-insulating material that is easily adapted to the skin can be formed. In addition, a heat storage effect can be obtained in the space between the fibers.

In this case, the water may be impregnated as an aqueous solution obtained by dissolving any substance, or may be fixed and impregnated or adhered to a superabsorbent polymer, or mixed with a water-soluble polymer to obtain a fluid. Alternatively, it can be impregnated or adhered as a semi-liquid.

Further, as the “conductive material”, an organic conductor gel or a sheet body coated or impregnated with an organic conductor gel can also be suitably used. Such an organic conductor gel is an excellent conductor per se, and can be heated by a microphone mouth wave, and can form a thinner, lighter and more flexible heat insulating material.

In the present invention, "livestock heat material" is 75 WZ (m.K) or less, particularly 10 WZ (m-K) or less, and especially 5 W / (mK) or less, based on the thermal conductivity. Preferably, the material is Further, based on the specific heat capacity, the material is preferably 0.46 kJ / (kg · Κ) or more, particularly preferably 0.5 kJ / (kg · K) or more.

Further, it is preferable that the “stock heat material” has a far-infrared radiation performance, in particular, an electromagnetic radiation performance in a wavelength band of 4 to 14 microns (photoelectron breeding light). Electromagnetic waves in the wavelength band of 4 to 14 microns are known to have a very high radiation efficiency of far-infrared rays and are also gentle on the skin. It is said to reach the capillaries, improve blood circulation, and activate metabolism. Preferable specific examples of the “stock heat material” in the present invention include ceramics (including pottery and glass), clay, and stone. Above all, fabrics / nonwoven fabrics formed from heat storage fibers obtained by kneading ceramics (including pottery and glass), clay, stone, and the like into fibers have excellent heat storage properties. The heat storage effect of such ceramics, clay and stone is already known, but among them, those having radiation performance of far infrared rays (especially a wavelength band of 4 to 14 microns) are particularly preferable. However, besides these materials, if the materials satisfy the above conditions of the thermal conductivity and specific heat capacity, an excellent heat storage effect can be expected, and the same heat insulating effect can be expected. .

Since the heat-insulating material for skin application of the present invention is used by directly applying to the skin, it is preferable that the portion corresponding to the skin has flexibility and conforms to the skin. For this purpose, a conductive material, a heat storage material, or both of them are formed into a flexible form such as a nonwoven fabric, a cloth, a sponge, or a sheet including a conductive material and a heat storage material. It is preferable that a flexible sheet such as a nonwoven fabric, a fabric, or a sponge is laminated on one or both sides of the body. At this time, the flexible sheet also functions as a heat transfer buffer layer, enhancing the heat retention effect and also preventing the high temperature portion from directly contacting the skin.

It is preferable that the outer surface of the upper and lower sides or both sides of the heat insulating material for skin application having the above-mentioned structure is covered with a plastic film by laminating a plastic film or applying a resin. If the outer surface of one or both sides is covered with a plastic film in this way, the heat insulating effect of the heat insulating material for skin application can be further enhanced. In addition, the evaporation of moisture inside the heat insulating material can be prevented.

The heat insulating material for skin application having the above configuration can be heated as it is in a microwave oven or the like. Preferably, any one of water, a water-soluble component, and an oil, or two or more of these components is applied or impregnated, and heated with the water, the water-soluble component, and the oil contained therein. At this time, the water is applied or impregnated in a form fixed to the superabsorbent polymer. Alternatively, it can be impregnated with an aqueous solution containing a lotion or other beautiful skin component or liratus component, or can be mixed with a water-soluble polymer to form a gel and then applied or impregnated. The water-soluble component can be applied or impregnated alone, or can be mixed with water to be applied or impregnated as a liquid or a gel. The oil has various effects such as a beautiful skin effect and a relaxing effect, and can be applied or impregnated with a safe oil on the skin.

By including these components, a moisturizing effect can be obtained at the same time as keeping the temperature warm.In addition, since these components are components that efficiently absorb microwaves and generate heat, they can further enhance the heat generating effect. Contribute. In addition, depending on the ingredients, it can also enhance the special relatas effect and beautiful skin effect.

A heat-insulating material for skin application comprising a sheet body, preferably a non-woven fabric, in contact with. That is, instead of the heat storage material such as ceramics in the above configuration, a sheet body such as a non-woven fabric having an outer surface coated with a film is laminated, and even in such a configuration, It has been confirmed that it is possible to obtain a heat-retaining effect that is not inferior to that obtained by laminating a heat storage layer made of heat storage materials such as ceramics. Needless to say, if the conductive material and the heat storage material are brought into contact with each other and a sheet body having an outer surface coated with a film is further laminated, a further heat retaining effect can be obtained.

In addition, the above-mentioned heat insulating materials for skin application are overlapped with each other, and the peripheral portions thereof are partially or partially left and joined to each other. Sex components, oils, etc. can be added and held here.

Furthermore, the above-mentioned thermal insulation material for skin application is resistant to deformation even when subjected to electromagnetic waves. It can be packaged in a heat-resistant film packaging bag and used as a heat insulating material for applying to the skin inside the packaging bag, so that it can be heated with a microwave oven or the like in the packaged state.

The heat insulating material for skin application of the present invention is heated by using an electromagnetic wave heating device, in particular, a microwave oven for home use that irradiates microwaves (radiation of electromagnetic waves near a frequency of 2,450 MHz), and heats the face, neck, Various medical effects such as swelling, improving blood circulation, massage effects, softening the stratum corneum, opening pores, slimming effects, etc. By promoting blood circulation and enhancing metabolism, various cosmetic effects such as dullness, darkness, swelling, and moisturizing effects can be obtained.

Further, by containing water and oil as described above, a moisturizing effect, a special relaxing effect, and a beautiful skin effect can be obtained.

It should be noted that it is easiest to use a microwave oven in view of the penetration rate into homes, but in the case of the present invention, it is also possible to heat using another electromagnetic wave heating device, for example, a high frequency induction heating device. It is possible. BRIEF DESCRIPTION OF THE FIGURES

It can also be formed from such materials. For example, papers, sheets made of thinly coated polyethylene or polypropylene resin on paper, polyethylene, polypropylene, polyester, polyvinyl chloride, polyamide, polyvinyl alcohol, polyethylene Moisture permeable and waterproof sheets such as phthalates, their copolymer films, resin foam sheets of these resins and polystyrene, nonwoven fabrics obtained by flash spinning, etc., and microporous films And a bag-like package made of the following. From the viewpoint of heat resistance, thermoplastic resins having both heat resistance and strength, such as polyester resin films such as polyethylene terephthalate and polybutylene terephthalate, especially crystallized polyester resin films A laminated film in which a heat-fusible resin film such as a polypropylene resin is dry-laminated or coated with a film as a base material and a sealant layer inside the bag is preferable. Polyolefin has a low dielectric constant and a small dielectric loss, so that it can effectively transmit electromagnetic energy to the inside and can be efficiently heated.

In addition, when heated in a microwave oven, the internal pressure increases due to the expansion of air in the bag-like package and the generation of water vapor, which may cause rupture.Therefore, a conventionally known method, for example, providing a vent hole or increasing the internal pressure Provide a ventilation path that allows ventilation and lowers the internal pressure, is formed so that the ventilation hole is exposed when the tape is peeled off, is formed so that it can be easily cut, and is partially formed of a non-woven fabric that has air permeability. To prevent internal pressure rise It is arbitrarily possible to provide them.

(Example 2)

As shown in Fig. 9, the thermal insulation material for skin application in this example is composed of 50% rayon, 20% PET, and 30% far-infrared PET kneaded with ceramic, entangled by the spunlace method. A 15 μπι thick PΕ film is laminated on a nonwoven sheet (having a basis weight of 30 g / m ² ) to form a sheet, which is shown in Fig. 7 (Α). Then, it was cut into a full face to form a mask.

This mask is then used for ceramides derived from natural yeasts (Ν-steaalloy norephy tosphigosin), oils, water-solubles, vitamins, other ichianoreseri, tea extract, ku extract, yo quin extract, peach leaves, fragrance Immersed in beauty water containing water, etc., fold the mask impregnated with the beauty water, put it in a plastic film / REM bag (a bag made of silica-vapor-deposited polyester film), and seal it, as shown in Fig. 10. Stopped. The spots in FIG. 9 and FIG. 10 indicate the hydration state of the beauty water.

The thermal insulation material for skin application in this example is obtained by cutting a plastic film bag, heating it to an appropriate temperature in a microwave oven, and then attaching it to the entire face and leaving it for an appropriate amount of time to improve the esthetic effect of heating. A relax effect can be obtained. At the same time, the action of ceramide derived from natural yeast can supply water to the stratum corneum and give the skin firmness and moisture.
