The present invention relates to a portable heat sheet, and more particularly, to a portable heat sheet including a thermal unit that can be easily attached and detached to the heat sheet as a component thereof so that the position and density can be easily adjusted as necessary.

According to the rapidly changing social environment, the pain or physical abnormality experienced by many people due to wrong lifestyle or wrong posture has been stabilized or mitigated by folk remedies such as light exercise. If left untreated, it can be a chronic illness, so it is best to get medication or physiotherapy as soon as possible.

The drug treatment or physiotherapy is applied to facilitate blood circulation in the area where the pain or abnormality occurs. When the medication is applied, there is a burden on the unpleasant smell of the drug or the stimulation of the drug itself. It is used to moisten a hot utensil, a hot water container or a towel, but it is difficult to carry on the body, and the use time is short, so it is inconvenient to replace frequently.

In order to improve the above problems, a portable product has been developed that relieves pain by supplying heat to an abnormal part of the body by a physical method.

On the other hand, a method of generating heat is to put a composition consisting of activated carbon, metal salts, moisture, and the like in a metal powder such as iron in a storage bag and attached to clothes, Japanese Patent Application Laid-open No. H7-194642 has a hole in the air Disposable stoves containing a heating element made of iron, activated carbon, salt, absorbent resin, water, and excipients in a storage bag, US Patent No. 5,906, 637 is designed to comfortably wear the composition containing the heating element on the knee or elbow, In Patent No. 6,336,935, both ends of the composition in which the heating element is housed are directly attached to the body. US Patent No. 5,837,005 attaches one side of the composition in which the heating element is housed to the user's clothes, and the other side touches the body. It discloses the method which is easy to use by the adhesive type to stick to clothes.                         

However, what is not entirely satisfactory for the devices is that many of the devices are not able to maintain a constant temperature or the volume of the heating device is large, resulting in unsatisfactory feeling. In addition, more specifically, the device can not be easily adjusted to comfortably be applied to various body parts, to provide only uncomfortable and unpleasant heating function to the body.

In order to overcome this disadvantage, Japanese Patent Application Laid-Open No. 5-58123 uses vertical stripes or checkered patterns on the synthetic resin nonwoven film to prevent heat transfer of the mixture and to provide a heat-generating Cairo which does not deform the synthetic resin nonwoven film package until the end of use. It describes filling thermocompression, sealing with seals, or wrapping with a Hochikiss needle, and Japanese Utility Model Model No. 3056594 describes Cairo, which created a partition to reduce the movement of heat generated. Japanese Patent Application Laid-Open No. 2000-288008 The arc prevents the flexibility of the heating element from deteriorating and maintains a good adhesion state so that it does not easily fall out. Make two or more checkerboards lose the heating element As it has been described for. However, in any case, when the moisture content of the exothermic composition is low, it is easy to be biased to one side, and even when it contains sufficient water or water-containing components, there is a problem of difficulty in manufacturing that requires the use of a special facility for dividing the sections of thermocompression or sealing. Will be.

In order to improve these problems, Korean Patent Publication No. 2000-0069809 discloses a heating pack containing a plurality of individual heat cells. After compressing the exothermic composition into hard tablets or slugs, heat cells, each typically circular in size from about 0.2 cm to about 10 cm in diameter and from about 0.08 cm to about 0.7 cm in height, are separately separated throughout the heat pack integrated structure. To be fixed. The heat pack applying the heat cell not only improved the adaptability to the body flexion portion but also improved the usability. However, in order to manufacture individual heat cells, the exothermic composition or the compressed product is added to a bag prepared in advance in the first continuous layer, and then the second continuous layer is disposed on the first continuous layer, and the two continuous layers are sandwiched using low heat. To form an integrated laminate structure. The bag of the first continuous layer is specified to be manufactured by thermoforming, mechanical embossing, vacuum embossing or other acceptable means. As described above, the patent has a lot of problems, such as the use of a specially manufactured device, the manufacturing process is very complicated, and the limitation of the film material and the prescription of heat generation. In addition, the fixed individual heat cell is not efficient if the user wants to control the amount of heating according to the nature and location of the pain.

1 illustrates a general portable heating sheet, in which a thermal unit 200 having a predetermined size is constantly arranged in a state contained in the adhesive sheet 100. Such a structure has the advantage of generating uniform heat throughout, but there is a problem in providing heat generated concentrated in a specific part of the human body.

Accordingly, the present invention was created to solve the above problems, and an object of the present invention is to manufacture a heating element in a separate thermal unit that is not fixed in an integrated structure having one or more continuous layers, and to use it as necessary. The number and position of the thermal unit can be freely adjusted and applied to the pain area of the body to facilitate the circulation of the blood by the steaming function by heat to provide a cold and pain relief effect.

In order to achieve the above object, the present invention is sealed sealing the exothermic composition containing iron, reaction promoter, water-retaining agent, binder and water in the moisture-permeable film and the one side is attached to the non-woven fabric or cotton cloth to form the skin contact surface and the other side Consists of a plurality of individual thermal unit that is formed by attaching a breathable film, a non-woven fabric or cotton cloth with irregularities to form an adhesive sheet attachment surface, and an adhesive sheet of a nonwoven fabric or a breathable film to detachably fix the thermal unit to the skin It provides a portable heating sheet.

Here, the thermal unit has a weight of 2.0 to 12.0g, it is preferably a triangular, rectangular, circular, elliptical, heart or star shape with a width of 2.0 ~ 6.0 cm vertical 1.0 ~ 5.0 cm.

In addition, the heating composition encapsulated in the thermal unit, a) 50.0 ~ 80 parts by weight of iron; b) a reaction accelerator comprising (i) 5.0 to 30 parts by weight of activated carbon containing 30.0 to 50.0% by weight of water, and (ii) 0.1 to 5.0 parts by weight of a metal salt; c) 0.5 to 10.0 parts by weight of repair agent; d) 0.5 to 5.0 parts by weight of the binder; And e) 10.0 to 30.0 parts by weight of water.

In addition, the moisture-permeable film is preferably a moisture permeability of 500 ~ 1000g / ㎡ / day.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. While many specific details are set forth in order to provide a more general understanding of the invention, such as the following description and the annexed drawings, these specific details are illustrative of the invention and are not meant to limit the invention thereto. And detailed description of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Figure 2 is a view showing a portable thermal sheet according to an embodiment of the present invention, Figure 3 shows a separate thermal unit 2 used in the portable thermal sheet according to an embodiment of the present invention, each thermal as shown The unit 2 is detachable from the adhesive sheet 1.

As shown in Fig. 2, each thermal unit 2 is used on the adhesive sheet 1, so that the user can arbitrarily select the attachment position of each thermal unit 2.

The thermal unit (2; thermal unit) is an exothermic system consisting of iron, a reaction promoter, a repair agent, a binder, and water, and manufactures a portable thermal sheet containing a thermal unit (2) that is not separated and fixed in the entire structure. It is possible. The thermal unit 2 is not only easy to manufacture as an individual heating unit, but also has a feature that is suitably applied to various body parts.

That is, in the thermal sheet according to the embodiment of the present invention, a plurality of separate thermal units 2 separately separated from each other, regardless of the continuous layer, the adhesive sheet 1 made of a nonwoven fabric or film, which is a continuous layer, as necessary in use. It can be used by adjusting the number and position of the.                     

Although the thermal unit 2 is shown in a circle in the drawing, it can be made in various shapes and sizes such as triangle, square, circle, oval, heart shape, star shape. However, in order to prevent the tilting and enhance the aesthetic effect, it is preferable to form a form filled in a triangle, a square, a circle, an oval, a heart, and a star having a width of 2.0 to 6.0 centimeters and a length of 1.0 to 5.0 centimeters.

In addition, the weight of the exothermic composition 21 filled in one thermal unit 2 is preferably 2.0 to 12.0 grams, which is less than 2.0 grams when the content of the exothermic composition 21 is too small to generate heat. Because the temperature and duration is very short, the thermal effect is weak, and if it exceeds 12.0 grams, the exothermic temperature and duration is excellent, but the thickness becomes thick, and the weight of the entire thermal sheet becomes heavy.

The thermal unit 2 mechanically encloses the exothermic composition 21 in a moisture-permeable film 22 having a moisture-permeability of 300 to 1,500 g / m 2, preferably 500 to 1,000 g / m 2, using a chemical adhesive or After sealing by physical high frequency or thermal adhesion, one side of the surface attaches a nonwoven fabric or cotton fabric to form a skin contact surface 23, and the other side attaches a breathable film, a nonwoven fabric or cotton fabric having irregularities to the adhesive sheet attaching surface (24). ) Is formed.

In order to avoid skin irritation, the skin contacting surface 23 may preferably use a nonwoven fabric or cotton cloth having a basis weight of 10 to 300 g / m 2, preferably 20 to 100 g / m 2.

In addition, the iron used in the embodiment of the present invention has a specific surface area of 100 to 120 m 2 / kg sponge type, the iron is preferably contained in 50.0 to 80.0 parts by weight. If the content is less than 50.0 parts by weight, there is a problem that the heat generation temperature and duration is shortened, and when the content exceeds 80.0 parts by weight, high heat may be generated during use, resulting in low-temperature burns.

The reaction promoter used in the present invention may use activated carbon and metal salts.

The activated carbon is preferably used to contain 30.0 to 50.0 parts by weight of water so as not to scatter the powder when manufactured in a fine powder form, the metal salt may be used as an electrolyte, sodium chloride, calcium chloride, potassium chloride, magnesium chloride, In the present invention, sodium chloride was used.

Preferably, the activated carbon is included in an amount of 5.0 to 30.0 parts by weight, and the metal salt is preferably included in an amount of 0.1 to 5.0 parts by weight. If the activated carbon is less than 5.0 parts by weight, the oxidation reaction catalyst action is weakened, the exothermic temperature is low, and if it exceeds 30.0 parts by weight, the action as a reaction catalyst does not increase any more. In addition, when the metal salt is less than 0.1 parts by weight, the reaction promoting effect is low, when it exceeds 5.0 parts by weight there is a problem that is difficult to dissolve in the water content used in the present invention.

The water-retaining agent used in the present invention may be used a glycerin, sorbitol, propylene glycol, 1,3-butylene glycol, polyethylene glycol, sugar, glucose and a superabsorbent polymer (SAP) crosslinked polymer.

The water retaining agent is preferably included in 0.5 to 10.0 parts by weight. If the content is less than 0.5 parts by weight, there is no repair effect, when it exceeds 10.0 parts by weight, the state of the heating element is wet, there is a problem coming out of the production.

The binder used in the present invention serves to improve the binding force between the heating element compositions, it is preferable to add the last of the heating element composition.

The binder may be a water-soluble polymer such as polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid or salt thereof, maleic anhydride copolymer, starch, carboxymethylcellulose, carrageenan, sodium alginate, pullulan, or derivatives thereof. It is preferably included in 0.5 to 5.0 parts by weight. If the content is less than 0.5 parts by weight, the bonding strength between the heating element composition is weak, and if the content exceeds 5.0 parts by weight, all of the moisture in the heating element is adsorbed so that the heating element itself becomes a powder in a dry state and thus cannot act as a binder.

The moisture used in the present invention is preferably included 10.0 to 30.0 parts by weight. If the content is less than 10.0 parts by weight, it is difficult to be processed into a powder form, when the content exceeds 30.0 parts by weight, the heating element is produced in a semi-solid state, there is a problem that heat is not generated in the presence of excess moisture.

The water is preferably added in a constant manner to obtain a uniform composition.

The exothermic composition 21 of the present invention may be prepared by a conventional method of mixing the above components and then evenly dispersing them to prevent lumps. After putting iron powder into the mixer, an aqueous solution in which the metal salt and the water-retaining agent were dissolved is added and mixed to form a uniform phase. Activated carbon is added thereto and stirred, and then a binder is added and mixed until it becomes a homogeneous phase to obtain the exothermic composition 21 of the present invention.
