  In other words, this type of magnetic plaster or acupoint stimulation plaster is applied to acupuncture points on the human body to promote blood circulation with magnetic lines of force or physically stimulate the acupuncture to treat low back pain or stiff shoulders. However, there is no scientific basis for the blood circulation promotion effect by magnetic force, the treatment effect is unstable, and the treatment to stimulate the acupuncture is painful and painful for some people. There is a problem of giving discomfort.

  Therefore, as a result of intensive studies to solve this problem, the present inventor has a film or sheet-like support on which activated carbon is supported as a bowl sheet to be used by sticking it to a point on the human body. As a result, it was found that extremely excellent pharmacological and therapeutic effects can be obtained without causing pain or discomfort to the user.

  That is, the present inventors pay attention to the fact that activated carbon has a negative ion generating action and a far-infrared radiation action, and by supporting the activated carbon having such characteristics on a support, the body (blood) that has absorbed negative ions. In other words, it was found that blood that became acidic due to the increase of electrons could be improved to weak alkalinity or blood circulation could be promoted by the thermal action of far infrared rays.

  In addition, the negative ion generation action and far-infrared radiation action in activated carbon are almost unaffected by the size of the activated carbon particles, and give almost the same effect even if they are not in direct contact with the skin. As a result, it is possible to remarkably improve the feeling of use by eliminating the skin irritation by making it into a powder or powder, or supporting activated carbon on the inside of the support or on the opposite side of the support surface of the support. It was also found that good disease treatment effects can be obtained without causing any pain or discomfort.

  In particular, when activated carbon is surprisingly applied to acupuncture points as a porridge sheet, the blood circulation of the acupoint points is promoted by the action of far-infrared radiation. As a result, the action of far-infrared radiation is further improved, which effectively eliminates or suppresses muscle stiffness and pain and further fatigue, restores fatigue, eliminates muscle pain and neuralgia, and activates the gastrointestinal function. In this way, it has been found that human health maintenance, disease treatment of the whole body or affected part, etc. can be performed.

  The present invention has been completed based on these findings, and when applied to acupoints, blood circulation in the acupoints is promoted, so that muscle stiffness and pain can be effectively eliminated or suppressed, To provide an active porridge sheet that can recover from fatigue, eliminate muscle pain and neuralgia, activate the gastrointestinal function to maintain human health, treat diseases of the whole body or affected area, etc. It is intended.

The active porridge sheet according to the present invention is a porridge sheet that is used by being affixed to an acupuncture point of a human body, characterized in that activated carbon is supported on a film-like or sheet-like support in the porridge sheet. To do.
Hereinafter, the active rice cake sheet of the present invention will be described in detail.

  The support used in the active rice cake sheet according to the present invention is not particularly limited as long as it is flexible and does not impair the feeling of use as the active rice cake sheet, and is composed of known natural fibers and / or artificial fibers. A film or sheet, or a film or sheet made of a polymer material can be appropriately selected and used, and a laminated film or laminated sheet in which at least one selected from these films or sheets is laminated is used. It's okay.

  Further, the activated carbon used in the activated rice cake sheet according to the present invention is not particularly limited, and activated carbon used for recovering industrial catalyst carriers, deodorizers, organic solvents, and the like can be used.

  The raw material for producing the activated carbon is not particularly limited, and a known activated carbon raw material such as wood, sawdust, dry wood, charcoal, coconut shell, or lignin can be suitably used. It is most preferable to use a coconut shell that is inexpensive, easily available, and has a dense structure.

  The active rice cake sheet according to the present invention has the greatest feature in that the activated carbon is supported on the film-like or sheet-like support described above.

  Here, the method for supporting the activated carbon on the film-like or sheet-like support is not particularly limited, and specifically, for example, a powdery or particulate form on the support surface using a binder such as an adhesive. If the activated carbon is adhered, or if the support is porous, powdered activated carbon is dispersed in a solution of water, lower alcohol, etc., and the support is immersed in this solution. The activated carbon may be supported on the surface.

  In the case where a pressure-sensitive adhesive layer to be described later is provided on the support, activated carbon may be included in the pressure-sensitive adhesive layer or activated carbon may be attached via the pressure-sensitive adhesive layer, and a plurality of supports In particular, in this case, a mixture of activated carbon and a thermoplastic resin powder is interposed between a plurality of supports, and the other side of the laminate is separated from the other side. The activated carbon may be fixed to the support by allowing water vapor to pass therethrough and melting the thermoplastic resin powder with the heat of the water vapor.

  By the way, the negative ion generating action and the far-infrared radiation action in the activated carbon give almost the same effect whether the activated carbon is in direct contact with the skin or not, so in the present invention, the activated carbon is supported. It may be carried on the sticking surface side of the body, on the opposite side of the sticking surface, or inside the support, but depending on the position where the activated carbon is supported on the support, the following new effects occur. It is.

  That is, in the bowl sheet in which activated carbon is supported on the sticking surface side of the support, the activated carbon protruding from the surface of the support is pressed against the surface of the body in use, so that the point is physically stimulated. In addition to the ion generating action and the far infrared radiation action, a synergistic therapeutic effect can be provided.

  In addition, in this case, if the activated carbon is formed into a molded body or a granular body or a powder body having a diameter of about 1.5 mm to 2.5 cm and a height of 3 mm or less, irritation to the acupuncture points is ensured and human pain is caused. In addition, the feeling of use is also improved.

  On the other hand, activated carbon supported on the opposite side of the support surface of the support can hardly give physical acupuncture stimulation with activated carbon, but has the advantage that there is no skin irritation and excellent usability. .

  Therefore, in the present invention, it is preferable to support activated carbon inside the support, and more specifically, the activated carbon is supported by sandwiching the activated carbon between two or more supports so that the garment can be used in use. The problem of fouling can be solved.

  In the present invention, the activated carbon supported inside the support is softly irritating to the acupuncture point because the activated carbon supported inside the support is pressed against the body surface through the support in use. As a result, a synergistic therapeutic effect can be obtained without causing pain or discomfort.

  By the way, in the present invention, the amount of activated carbon supported on the support is appropriately determined according to the particle size, activity or use of the activated carbon, and is not particularly limited. Is preferably about 10 to 200 parts by weight of activated carbon with respect to 100 parts by weight of the support.

  In the present invention, when the amount of activated carbon supported is less than about 10 parts by weight with respect to 100 parts by weight of the support, the required therapeutic effect cannot be obtained because it is too small to obtain the required blood circulation promotion. On the other hand, if the amount of activated carbon exceeds about 200 parts by weight, the therapeutic effect is limited, which is not only meaningless but also uneconomical. Is more preferably about 15 to 150 parts by weight.

  In the active porridge sheet according to the present invention, in order to obtain a synergistic and multifaceted therapeutic effect or to further improve the therapeutic effect, it is affixed to the outer skin to maintain human health, disease of the whole body or affected area It is preferable to carry a liquid, powdery or granular functional substance used for treatment or disease prevention, or for imparting skin beautification or whitening effect.

  As this functional substance, various functional substances can be appropriately selected and used depending on the application, and are not particularly limited.

  Other medicinal ingredients include at least one selected from sublimable crystals, mint oil, eucalyptus oil, lavender oil, and the like.

  Next, the cosmetics are used in a manner similar to these to clean, beautify, enhance attractiveness, change the appearance, or keep the skin healthy in order to keep the skin clean. Although it is not particularly limited as long as it is intended to be applied, general cosmetics that have a mild effect on humans can be appropriately selected and used. Specifically, for example, Anti-inflammatory agents, astringents, refreshing agents, vitamins, hormones, antihistamines and other rough skin prevention agents, sebum suppressants, acne exfoliating / dissolving agents such as acne, aloe extract, salmon extract, aroma essence, carrot There may be mentioned at least one selected from animal and plant extracts such as extracts, persimmon extracts and licorice extracts, and nutrients such as amino acids.

  The negative ion generator is not particularly limited as long as it generates negative ions. Specifically, for example, tourmaline, rare earth ore, dilute stone, amber, black carbon, garnet, There may be mentioned at least one selected from coral stone, thoron, diatomaceous earth and the like.

  Further, the far-infrared radiator is not particularly limited as long as it has a function of suitably emitting an electromagnetic wave having a wavelength range in the vicinity of the far-infrared region. Inorganic solids (far-infrared radiation ceramics) are preferable. Specifically, for example, at least one selected from metal oxides, carbides, nitrides or carbonates can be appropriately selected and used.

  In addition, the magnets promote blood circulation to eliminate stiff shoulders, improve back pain, etc., and include magnets having a granularity of 500 gauss or more.

  In the present invention, a metal powder such as copper powder or zinc powder expresses a bactericidal action or an antibacterial action, and is used to improve the health condition of the outer skin of the application site. Of these, copper powder is particularly desirable because it effectively exhibits the bactericidal action and antibacterial action.

  In the present invention, a plurality of the above-mentioned various types of functional substances may be combined. Specifically, for example, at least one selected from herbal medicines or extracts from plants and a magnet or distant The combination with at least 1 sort (s) selected from the infrared radiator is mentioned.

  By the way, in the present invention, the amount of the functional substance to be carried on the support varies depending on the type and use of the functional substance and is appropriately determined, and is not particularly limited. The functional substance is preferably about 5 to 500 parts by weight with respect to 100 parts by weight of the support.

  In the present invention, when the loading amount of the functional substance is less than about 5 parts by weight with respect to 100 parts by weight of the support, the required therapeutic effect cannot be obtained because the amount is too small. When the amount of the active substance exceeds about 500 parts by weight, the therapeutic effect is limited, which is not only meaningless but also uneconomical. More preferably, the substance is about 10 to 250 parts by weight.

  In the present invention, these functional substances are at least selected from a stabilizer, an anti-aging agent, an antiseptic, an antifungal agent, a surfactant, an ultraviolet ray preventing agent, a weathering agent, and the like, if necessary. An appropriate amount of one kind may be mixed.

  In the present invention, the method for supporting these functional substances on the support is not particularly limited. Generally, the surface of the support is used in the form of powder or particles using an adhesive or a pressure-sensitive adhesive. If the functional substance is adhered, adhered, or the support is porous, the powdered functional substance is dissolved or dispersed in a solution such as water or lower alcohol, A method of supporting a functional substance in the support by immersing the support in this solution can be mentioned.

  By the way, in the active rice cake sheet according to the present invention, activated carbon is supported on the support, and simply attaching it to the outer skin may cause displacement or dropping. It is necessary to fix the active porridge sheet at the position where the outer skin is applied using a fixing means such as the above.

  Therefore, the active rice cake sheet according to the present invention preferably includes a pressure-sensitive adhesive layer on a part or all of the skin (outer skin) application surface side of the support.

Styrene rubber adhesive, nitrile rubber adhesive, butyl rubber adhesive, urethane rubber adhesive, acrylic rubber adhesive, or acrylonitrile rubber adhesive.

  In the present invention, the above-mentioned pressure-sensitive adhesives may be used alone or in combination of two or more.

  In the active rice cake sheet according to the present invention, its shape and size are not particularly limited as long as it can cover the point of the pot, but in general, handling property, portability, storage property, etc. In view of the above, it is desirable that the shape is a circle, a polygon such as a quadrangle, an ellipse or the like, and the size is 2 to 4 cm.

  The active porridge sheet according to the present invention has the above-described configuration, and the active porridge is formed in a sheet shape, so that it does not cause pain or discomfort to the user even if it is applied to a pot point, In particular, when activated carbon is surprisingly applied to acupuncture points as a porridge sheet, the blood circulation of the acupoint points is promoted by the action of far-infrared radiation. As a result, the action of far-infrared radiation is further improved, which effectively eliminates or suppresses muscle stiffness and pain and further fatigue, restores fatigue, eliminates muscle pain and neuralgia, and activates the gastrointestinal function. As a result, it is possible to maintain human health, treat diseases of the whole body or affected area, and the like.

  That is, in the activated rice cake sheet according to the present invention, attention is paid to the fact that activated carbon has a negative ion generating action and a far infrared radiation action, and the activated carbon having such characteristics is supported on the support to absorb the negative ions. Electrons increase in the body (blood), and the blood that has become acidic can be reduced to weak alkalinity, and blood circulation can be promoted by the thermal action of far-infrared rays.

  Further, in the active porridge sheet according to the present invention, the negative ion generating action and far-infrared radiation action in the activated carbon are hardly affected by the size of the activated carbon particles, and are almost the same even if they are not in direct contact with the skin. In order to give an effect, the activated carbon is made into particles or powder, or the activated carbon is supported on the inside of the support or on the opposite side of the support surface of the support to eliminate the skin irritation and remarkably improve the feeling of use. As a result of the improvement, it is possible to effectively eliminate stiff shoulders and the like without causing any pain or discomfort to the user.

  Hereinafter, although the present invention is explained in detail based on an example, the present invention is not limited to this.

  FIG. 1 is a schematic view showing an active porridge sheet 1 according to the present invention. FIG. 1 (a) is a cross-sectional view thereof, FIG. 1 (b) is a front view as seen from the sticking surface side, and FIG. The front view seen from the other side of the sticking surface is shown.

  The active porridge sheet 1 shown in FIG. 1 is obtained by adhering and fixing a sheet-like activated carbon 3 through a pressure-sensitive adhesive layer 4 to the approximate center of a circular support 2. Since the activated carbon 3 protruding from the surface is pressed against the body surface side, the acupuncture point is physically stimulated, and the far-infrared radiation action and the negative ion generation action are expressed by the sheet-like activated carbon 3. In addition to promoting blood circulation in the acupuncture points by the infrared radiation action, electrons increase in the body (blood) that has absorbed negative ions by the negative ion generation action, and the acidified blood is improved to weak alkalinity. An effective therapeutic effect is obtained by the synergistic action.

  The activated carbon 3 is a mixture of powdered activated carbon (coconut shell activated carbon 50-80 mesh, the same applies hereinafter) and polyethylene powder (average particle size of about 45 mesh) in a weight ratio of 2: 1, and this mixture is mixed with a diameter of A mesh body (mesh 150 mesh) that is bent so as to form a circle of 2.5 cm and a depth of 1.5 mm is filled, and water vapor at a temperature of 180 ° C. is transmitted from one surface to the other surface for 20 seconds. This is formed into a diameter of 2.5 cm and a thickness (height) of 1.5 mm.

  By the way, the pressure-sensitive adhesive layer 4 is formed using an acrylic pressure-sensitive adhesive. The activated carbon 3 is supported on the support 2 and, when applied to a pot point as a rice cake sheet, the rice cake sheet 1 is pasted on the skin surface. It plays a role to wear.

  That is, the activated rice cake sheet 1 shown in FIG. 3 is one in which granular activated carbon 3 is supported so as to be sandwiched between two circular supports 2 (2a, 2b). Since the granular activated carbon 3 carried inside the body 2 (2a, 2b) is interposed between the supports 2a, 2b and pressed against the body surface side, it can soften the acupuncture points, resulting in pain and discomfort Furthermore, the far-infrared radiation action and the negative ion generation action are expressed by the granular activated carbon 3, and this far-infrared radiation action promotes the blood circulation in the acupuncture point and the negative ion generation action. Electrons increase in the body (blood) that has absorbed negative ions due to this, and the acidified blood is improved to weak alkalinity. On fruit is obtained, in which it is possible to solve the problem of soiling the clothing.

  The activated carbon 3 is a net obtained by mixing powdered activated carbon and polyethylene powder in a weight ratio of 2: 1 and bending the mixture into a circle having a diameter of 7.5 mm and a depth of 3.5 mm. A body (150 mesh mesh) is filled, and water vapor at a temperature of 180 ° C. is passed through from one side to the other side for 30 seconds to form a diameter of 7.5 mm and a thickness of 3.5 mm.

  By the way, the pressure-sensitive adhesive layer 4 plays a role of sticking the active porridge sheet 1 to the skin surface in use.

Powdered activated carbon, magnet powder (disc shape with a diameter of 0.75 mm, 1500 gauss) and copper powder (50-60 mesh) are mixed at a weight ratio of 2: 1: 0.1, and this mixture is mixed with an EVA emulsion. (Supplied by Sumitomo Chemical Co., Ltd., trade name: SUMIKAFLEX) The entire surface of a support (round 10 cm in diameter) made of cotton (basis weight 80 g) while stirring the mixed dispersion so that the mixed dispersion is not separated as much as possible The mixture was fixed on the support by drying with suction at 120 ° C. after suction filtration using an aspirator while flowing down uniformly.
The amount of the mixture supported was 175 parts by weight of the mixture with respect to 100 parts by weight of the support.

  Next, after applying a solution of an acrylic pressure-sensitive adhesive to the mixture side in the obtained rice cake sheet, drying to form a pressure-sensitive adhesive layer, and further laminating a release sheet on this pressure-sensitive adhesive layer, The active rice cake sheet of the present invention was obtained by cutting into 2.5 cm long and 2.5 cm wide squares.
