Falling of the charcoal powder is substantially prevented by laminating a thin pressure sensitive layer on the viscous substrate layer with charcoal powder. The black color is obscured by using a white colored pressure sensitive layer. A sustained release sheet is obtained by absorbing medicine on the charcoal of the sheet. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to a carbon / charcoal patch sheet for humans / animals, that is, a patch sheet / bandage of charcoal powder.

  Traditionally, carbon and charcoal have been used to absorb odors, remove impurities in water, and be added with rice to improve the taste of rice during cooking. There are also bamboo charcoal bars that are made into pillows. There are also confectionery products that are coated with charcoal and eaten to absorb toxins in the body. Recently, it has been found that carbonizing the cotton, putting it in the place of the cotton in the bed, and sleeping on it reduces the viscosity of the blood. Carbon and charcoal, especially carbon made from natural organic matter, have surprising effects. However, when it is used as a bed, if it is not covered very carefully, it will leak from the tissue of the cloth, the surroundings will become black, become trash, enter the respiratory organs, and look bad. There was a significant flaw in meaning. In order to improve the effect, walking with a charcoal stick as a back sac was heavy, bulky, heavy and hard, and there were similar defects such as injury.

  However, for example, when the knee of the foot is injured by a bruise, a poultice containing an anti-inflammatory agent or an analgesic (the adhesive film containing the chemical, the release film, and the stretch film is peeled off and applied to the affected area. However, the swelling is very difficult to reduce unless exercise is given to the entire area beyond the knee and to the foot. Exercise helps to promote circulation and increase swelling. However, because it swells up, it hurts and it is difficult to exercise. That is contradictory. As an auxiliary means, when trying to add the effect of charcoal, there were defects such as bulky and heavy. On the other hand, Bincho charcoal generated a lot of cutting waste, and a place to use it economically was demanded. These known charcoal (including equivalents, including carbides) had the common problems of dirt and heavy, hard, and unwieldy. Sheets to which various drugs such as camphor and light load are applied are also known, but they have poor release properties, and when applied to the skin, there is a serious defect that they work immediately and the effect decreases immediately.

The present invention solves these problems, prevents the scattering of black charcoal, exerts a smooth blood flow effect, and performs hygienically the auxiliary effect of causing swelling due to blood flow promotion as in the above example. The goal is to make things, and to coordinate them closer to the skin. An object of the present invention is to provide a charcoal sheet that can be easily manufactured and promotes the pulling of swelling, and that can be easily used in a poultice that is easily used every day. As shown in the example, the objective is to resolve the contradiction of insufficient blood circulation due to lack of exercise due to pain (environmentally without relying solely on drugs).

In a patch or composite bandage, a charcoal powder pasting composite sheet comprising at least a fabric layer and a layer containing a polymer, wherein at least the polymer layer is contained as charcoal powder or a structure close thereto. .
(11) In the above 1, 2, 3, 4, 5, 6, 7, 8, and 10, the charcoal is in the adsorbed state of the adsorbed material, and the composite sheet with controlled release charcoal is provided.

Here, the fabric includes a woven fabric, a knitted fabric, a nonwoven fabric, a papermaking nonwoven fabric, a spunbond, a flash spun nonwoven fabric, a spunlace, a porous film, a porous solidified sheet, and the like. The fibers include natural fibers, synthetic fibers, and recycled fibers. Ultra-fine fibers and hollow fibers, all of which are irregular cross-section fibers, composite fibers, crimped fibers, and rubber-like fibers are also included. I don't give all examples of fiber materials. Various rayons including bamboo rayon, various cotton, nylon 6 and 66 fibers, polyester fibers, crimped composite fibers, polypropylene fibers, polyethylene fibers, polybutylene terephthalate fibers, polytrimethylene fibers, polyvinyl alcohol fibers, polyurethane elastic bodies Fiber, polyester elastic fiber, etc. are all included. Organic polymers are preferred, but carbon fibers may also be used. There are many fabric or sheet forms shown in the JPO Digital Library. The charcoal is preferably any charcoal such as Bincho charcoal powder, miscellaneous charcoal powder, cotton charcoal powder or fibrous powder, bamboo charcoal powder, grass charcoal powder, charcoal from coconut shells and straws, and various carbon fiber powders. Only diamonds are excluded. Charcoal from plants is particularly preferred. The powder size is preferably 10 mesh or less and close to nano order. Even large sizes include everything that is sub-thinned during mixing with polymers and substrate-like materials. In terms of price, those by-products are industrially preferable. This is because it can be used effectively.

High molecular weight for application (including ointment), that is, adhesive layer, base layer, base layer, high molecular meaning including copolymer, polymer of unsaturated phase molecule Well-known adhesive polymers are heretofore included even if not specifically described, such as natural rubber polymers, synthetic rubber polymers, polyacrylic compounds, and vinyl polymers such as polyvinylpyrrolidone. Of course, additives, chemicals, colorants, pigments, extenders, inorganic particles, for example, JP-A-2003-213222, 2001-009985, JP-A-07-284507, and JP-A-2004, including other examples of additive chemicals. -259594, Japanese Patent Application Laid-Open No. 2004-143052, Japanese Patent Application Laid-Open No. 2004-188218, etc. Additives / chemicals for other purposes may be added to the present invention. In particular, sticky polymers are optimal because they capture powdered charcoal well and prevent scattering. At the same time, it sticks well to the fabric and is also excellent for sticking to the body. The effect of the third power can be demonstrated.

Examples of the base material include acrylic copolymers, block copolymers thereof, for example, block copolymers of monovinyl-substituted aromatic compounds and conjugated diolefin copolymer pairs, and alicyclic petroleum resins, softeners ( Examples: those having higher fatty acids, liquefied rubber, mineral oil) are also used. Furthermore, polybutene rubber, butyl rubber, and silicone rubber are also used. Furthermore, tackifiers such as terpene resins and petroleum resins, animal and vegetable oils such as liquid paraffin, olive oil, soybean oil, beef tallow and lard, adhesive and retention modifiers such as polybutene, lower isoprene and wax, titanium oxide In addition, fillers / coloring agents such as zinc oxide, aluminum metasilicate, calcium sulfate, calcium phosphate, and hiding agents may be blended. The pressure-sensitive adhesive layer preferably contains moisture so as to improve the thermal conductivity to the skin and is excellent in adhesiveness. It is preferable that it softens at 38-44 degreeC and the black of charcoal of a base material layer does not remain.

The addition of a water retention agent is also preferred. Water-absorbing polymers are typical. Crosslinks may be introduced into it. Many commercial products are seen in these. In addition, carboxymethyl cellulose polyacrylic acid soda, kaolin, vermiculite, silica powder, wood powder, gelatin, titanium oxide, and various crosslinking agents for polymers can be used. By these, charcoal retainability, anchoring force, adhesive force, and cohesive force can be adjusted. Water is also effective, and water, hot spring water, saline, glycerin, mint oil, methyl salicylate, glycol salicylate, alcohols, fatty acid esters, menthol, camphor, non-steroidal agents, and surfactants are also used. As the non-transferable pressure-sensitive adhesive, those into which a rubber-based, acrylic-based, or vinyl acetate-based polymer reactive functional group is introduced are used.

The direct purpose can be fulfilled without the addition of other drugs, ie alone. The sheet is preferably attached to the skin because it is easy to use, but may not be attached like a bandage. You may use it so that an adhesion layer may become the outside. It is convenient for those who wear a polymer. Here, it is called carbon or charcoal, but the former is a superordinate concept and is substantially the same, but charcoal is made from plants such as ordinary wood and bamboo. Those made from natural plants such as bamboo and wood are preferred. In particular, Bincho charcoal is an excellent charcoal, but the present invention has an excellent feature that the cutting powder, which is considered to be poorly used, can be used effectively. When carbon or charcoal reaches 25% or more, particularly preferably 30% or more with respect to the polymer, the electrical conductivity tends to increase rapidly. It is presumed that the cause is a continuous chain of carbon particles. In the present invention, the amount of charcoal is better up to the amount where the carbon scattering prevention effect of the polymer continues. There is a strong tendency to make blood smooth. Heat conduction is also generally increased.

This mixture may be soaked in the fabric, but may be coated or pasted. A part of the coating also penetrates, but in general it is called a layer. Needless to say, in order to prevent sticking, if the film equivalent for peeling is affixed and placed, it can be peeled off and used immediately after use. In the case of high rate mixing of charcoal, the residue may stain the skin and kimono when it is applied to the skin. It is preferred to leave Of course, a material excellent in pasting property is preferable. In other words, a high rate of charcoal is put in the intermediate layer. The intermediate layer may not be the entire surface, but may be partially or in any pattern, or may be sandwiched. This sheet can be applied not only to humans but also to animals. It is better to have two or more layers in part, and less than others. Needless to say, the sheet includes a three-dimensional structure obtained by processing the sheet. For example, it is needless to say that all shapes such as a tubular shape, a clothing shape, a hat shape, shoes, gloves and a gaiter shape are included.

The peeled film or peeled film layer can be taken as a peelable protective layer and can also be called a peelable liner, but various sheets and films such as polypropylene, polyethylene, polyester, polyvinyl chloride, polyvinylidene chloride polystyrene, etc. Used as appropriate.

According to the present invention,
(1) Charcoal fibers, blocks, and charcoal powder are not covered with cloth or handled directly.
(2) Affixed easily.
(3) There is an auxiliary effect of blood flow promotion. (Carbon is known for its effect on making blood smooth.)
(5) It is easier to handle because it is less bulky and flexible than handling close-up Bincho charcoal.

(6) The powder produced in the charcoal manufacturing process can be used effectively.
(7) Waste cotton, linter, rice husk charcoal, carbonized fallen leaves, charcoal of tree twigs, coconut husk, etc. that are not suitable for ordinary use can also be used effectively.
(8) Don't get hurt like a charcoal stick. Scattering of charcoal powder and charcoal fibers does not enter the lungs.
(9) Fragments, powders, etc. that are difficult to make into fine products that occur in the charcoal manufacturing process can be effectively used.
(10) Since it is in the form of a sheet, sewing products of any shape can be made. (Such a thing is within the scope of the present invention.)
(11) The material covering the base layer prevents the charcoal from adhering to the skin, and the material using the masking agent does not notice the blackness.
(12) There is also a cooling effect by charcoal.
(13) Combination with other chemicals, that is, analgesics, anti-inflammatory agents, vasodilators, skin stimulants, muscle relaxants, various hormones, emollients, vitamins, hemostats, Chinese medicines, antibiotics, etc. However, there is a special effect unique to the combination with charcoal that does not work on extremes (it is unlikely to cause rashes, etc.) and works gradually on average. Moreover, charcoal is excellent in its adsorption power and quantity.
(14) Since the chemical is adsorbed onto the charcoal and kneaded, it has an epoch-making effect that it is far easier to knead than kneading directly into an adhesive polymer. There is much less chemical splashing directly as a gas or liquid.

In the present invention, in consideration of production, it is preferable that the fabric is provided with a charcoal intermediate layer on the entire surface and an overcoat layer is provided again thereon. For coating, transfer, gravure coater, knife coater, transfer coater, spray, etc. can be used effectively. As the fabric, a stretchable fabric is particularly preferable in consideration of aspects such as knees and shoulders. What extends 15% or more is preferable. Fibers having elastic properties and crimpable fibers are preferred. An adrenal cortex hormone effective for inflammation such as bruise, various anti-inflammatory agents, various anti-inflammatory agents, and vasodilators may be mixed in the adhesive layer. That is, there are many anesthetics, analgesics, antipyretic anti-inflammatory agents, steroidal anti-inflammatory agents, skin stimulants, muscle relaxants, various hormone agents, emollients, vitamins, hemostatic agents, Chinese medicines, antibiotics, etc. . In the case of chemicals, even if they are singularly effective without harm, in the case of mixing, they do not necessarily work additionally. All require prior testing. The same is true for herbal medicine. In addition to contraindications, it is necessary to confirm the effects on the body. In general, careful attention to food is required. All meals that are said to be bad for the illness must be avoided. If there is a relationship with drugs, it is even more so. In general, there is a general social tendency that tends to be accompanied by behavior that is too modest. Examples of the above-mentioned substances are also listed in JP2003-213222.

  As a result of testing, I noticed that the problem of charcoal is low, and there is little problem at low rate. It is to say that fouling occurs. The idea was that the charcoal mixture was directly covered on the skin so as not to touch it. Therefore, this problem was brilliantly solved by covering the base material layer with a cover layer that was covered with an adhesive layer. Of course, it is needless to say that it is preferable to provide a peeling film portion thereon. To put it simply, it is a structure that covers what gets dirty with something that doesn't get dirty.

  In addition, what was found by testing was that it could cause problems for some people. Surprisingly, there was a problem even if it was covered with another layer as described above. It is a human sensitivity issue. In other words, it is a psychology that black things don't want to touch the skin directly. In other words, in the above coating layer, it was transparent and still black. It has been found that the problem can be greatly reduced if the coated adhesive layer is whitened. In other words, it was possible to solve this problem by adding pigments and colorants having strong hiding power, such as titanium oxides and barium sulfate. Again, the opposite appeared again. In other words, as in the case of soap with charcoal with many loyal customers, it is the opinion that it is more effective to remain black, and if there is an effect, the dirty part will not scatter, so it can even be washed away. Is n’t it good? It is added that it is an opinion. In addition, charcoal is easy to adsorb and sorb organic compounds such as camphor and thin load, and when it is in the state of the present invention, charcoal adsorbs chemicals, and therefore removes them without releasing them at once. It was found to have release. In addition to the charcoal effect, it cannot be overlooked that in combination with various chemicals, there is no particular feature of sustained release, that is, there is no radical effect, and there is a unique effect that the effect does not decrease immediately.

Next, based on an Example, the aspect of this invention is demonstrated in detail, However, This invention is not limitedly interpreted by these.

  A silicone surface-treated polyester film was coated with a 10% solids concentration isopropanol mixture containing 50 parts of Bincho charcoal powder and 50 parts of polyvinyl pyrrolidone at a 10 g / square meter dry rate. A mask using a stretchable nonwoven fabric was diverted, pressed and transferred to a stretched nonwoven fabric collected from the mask, and the film was peeled off to form a composite layer of a polymer and a carbon layer. On the other hand, an ultrathin coating of a polyester film having a silicone surface-treated copolymer (ethyl acetate solvent) of 2-ethylhexyl alcohol and 95 parts of an acrylic acid ester was dried to form an adhesive layer. Finally, it stuck together so that the carbon layer might be covered, and formed the patch layer containing charcoal in the middle. It happened that there was a person who cleared his knees and cleared it, so he peeled off the film and stuck it on half of his shin. It was pasted well. In addition, hitting the knees only swollen at the half-moon bang, shin, and feet, and the thighs do not swell despite being strangely close. When observed in this way, the part (A) pasted in this way promoted blood flow and the swelling was reduced.

Comparative Example 2

For comparison, in place of the above-mentioned Bincho charcoal powder, a product using magnesium metasilicate aluminate (B) and a product containing nothing (C) were prepared and compared in the same manner as in Example 1. When observed in this way, the parts (B) and (C) pasted in this way, no effect was observed.

In Example 1, what made thin charcoal adsorb | suck to charcoal was used. This was a long lasting effect of thin load. On the other hand, the one that kneaded the light load directly works at a stretch, but after a while, the smell of the light load became weak. This is sufficient with the difference in sniffing with the most effective nose for analysis, but it was clearly seen in the skin sensation after 6 hours.

After heating and dissolving 100 parts of styrene-isoprene-styrene teleblock copolymer, 10 parts of styrene-isoprene copolymer, 150 parts of liquid paraffin, and 50 parts of rosin-modified maleic resin, add 35 parts of bamboo charcoal powder to the whole. , Mixed. After that, it was carried out in the same manner as in Example 1, but titanium oxide was added to the coating layer by 0.7% of the weight of the coating portion, and the black color of the carbon portion in the positional relationship between the nonwoven fabric and the non-woven fabric was greatly increased. The result was such that it was not necessary to be conscious of black. Moreover, since it is flexible, it was able to be pressed against the elbow of the right arm. Bending and stretching was possible.

The present invention can produce a sheet of a patch for promoting blood flow, can be controlled, and can produce a reproducible sheet. It can be widely produced as a patch for humans, animals, injured, tired, and edema, and is useful for humans and animals that need it.

Combinations with other drugs are also possible. It was reduced from the extreme effect, and an epoch-making sticking effect that it could be heard for a long time was recognized, so it can be used in that field. Also, since it is a sheet-like material, various clothes including knee pads, arm covers, hats, shoes, bags, bed covers, duvet covers, car seats, chairs, pillow cellphone cases (bags), bands, wheelchairs, trains It can also be used effectively for silver sheets, toilet seat covers, feet of sinks, curtains, electromagnetic shielding covers, etc.
