Hereinafter, the hot pack to which the above-described mugwort hydrogel is applied will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a hot pack coated with mugwort hydrogel according to an embodiment of the present invention.

The present invention encloses a heating element (20) generating heat by an exothermic reaction inside the packaging film (10), wherein the packaging film is a hot pack comprising a nonwoven fabric (10a) and a breathable film (10b) attached to the nonwoven fabric In, it provides a hot pack coated with mugwort hydrogel that can be attached to the skin by applying mugwort hydrogel to one surface of the packaging film 10.

Hot pack coated with mugwort hydrogel according to an embodiment of the present invention comprises a heating element 20 and a packaging film 10 encapsulating the heating element 20, wherein the packaging film 10 is a nonwoven fabric 10a, Includes a breathable film (10b) attached to the outside of the nonwoven fabric (10a), and wraps the outer surface of the mugwort hydrogel and the mugwort hydrogel on one surface of the packaging film (10b), preferably the breathable film (10) A cover sheet 40 may be further included.

The periphery of the packaging film 10 for encapsulating the heating element 20 is heat-pressed to form a sealing surface 50, and the sealing surface 50 can be chamfered or rounded to improve safety during use.

In addition, in the hot pack according to an embodiment of the present invention, a sealing spot 51 may be formed, and the sealing spot 51 prevents the flow of the heating element 20 therein so that the user downwards when attached to the human body The heating element 20 may be prevented from being driven, and it may be prevented from flowing according to a user's movement, thereby providing convenience of use.

The non-woven fabric 10a is a fabric made by mechanical treatment so that fibers are entangled with each other, and has a soft texture, good texture, and excellent tensile strength.

As the nonwoven fabric 10a, polypropylene spunbond nonwoven fabric, polypropylene melt blown nonwoven fabric, polypropylene thermal bond nonwoven fabric, nylon nonwoven fabric, polyester nonwoven fabric, and the like may be used, and combinations thereof may also be used.

The breathable film (10b) can be produced by mixing an inorganic material, a dispersant, etc. in a base resin, then melting and stretching, and in the stretching process, fine pores are formed between the base resin and the inorganic material to have breathability, and moisture does not pass. It has the effect of increasing the exothermic time by controlling the rate of the exothermic reaction (oxidation/reduction reaction) of the heating element.

As the base resin, polyethylene, polypropylene resin, or the like can be used. Specifically, polyethylene resin of linear low density polyethylene (LLDPE) or low density polyethylene (LDPE) may be used, and metallocene polyethylene (m-LLDPE) may be further included. . The use of metallocene polyethylene (m-LLDPE) has an effect of easily controlling air permeability during stretching, and the content thereof may be 5% to 20% by weight in the base resin.

As the inorganic material, titanium dioxide (TiO₂), silicon dioxide (SiO₂), calcium carbonate, barium sulfate, zeolite, clay, etc. can be used.

Meanwhile, the non-woven fabric may be laminated to the stretched breathable film using a hot melt or liquid adhesive, or embossed to bond the breathable film and the non-woven fabric. During extrusion molding of the contained polymer film, it can be produced by laminating a nonwoven fabric in a molten state of the extruded film and stretching the nonwoven fabric laminated film on a rolling roll.

The heating element 20 is composed of iron, moisture, and electrolyte, and may include activated carbon, vermiculite, absorbent resin, and the like. Iron reacts with water and oxygen to cause an oxidation reaction, as shown in the following reaction formula, and iron (powder) with a large specific surface area is used to facilitate oxidation.

Oxidation: Fe → Fe ²⁺ 2e ^-

Reduction reaction: O₂ (g) + 2H₂O ( l) + 4e - → 4OH - (l)

Fe ²⁺ made in the oxidation region moves to the reduction region through water (moisture) on the iron surface, and this Fe ²⁺ reacts with oxygen to form iron oxide.

4Fe ²⁺ (aq) + O₂(g)+ (4+2n)H₂O(l) → 2Fe₂O₃2n(H₂O)(s) + 8H ⁺ (aq)

That is, the outside air enters the inside of the hot pack, and the entire oxidation/reduction reaction occurs, whereby iron (iron powder, Fe) is oxidized to become iron oxide.

The iron powder according to an embodiment of the present invention has a specific surface area of 50 to 200 m 2 /kg, and the proportion of the iron powder in the total heating element may be 30 to 90% by weight. If the content of iron is too small, there is a problem that the heating temperature is low or the heating duration is short, and if the iron content is too high, there is a risk of high heat.

On the other hand, since the present invention includes a breathable film that controls the inflow of air (oxygen), a rapid exothermic reaction does not occur even if the iron content is high, and there is an effect of continuously maintaining the exothermic time.

In order for the oxidation/reduction reaction to occur smoothly, an electrolyte that serves as an electron transport path is required. For this, electrolytes such as sodium chloride, calcium chloride, potassium chloride, and magnesium chloride can be used.

The mass ratio occupied by the electrolyte among the entire heating elements is preferably about 0.1 to 10% by weight, but may exceed the above range.

Activated carbon is adsorbed to iron and serves to supply oxygen for oxidation of iron, thereby promoting heat generation.

Vermiculite has an excellent energy absorption effect, so it effectively absorbs heat generated from iron and plays a role in maintaining the exothermic effect.

Meanwhile, the hot pack coated with mugwort hydrogel according to an embodiment of the present invention is coated with mugwort hydrogel 30 on one surface of the packaging film 10, preferably the breathable film 10b.

The wormwood hydrogel contains 50-60% hydrogel, 30-35% by weight of wormwood extract and 5-10% by weight of natural adhesive components, and the natural adhesive components include ivy sap and aqueous starch solution.

On the other hand, when the wormwood extract is used in an amount of less than 30% by weight, the efficacy of alleviating gynecological disease is negligible, and when it is used in excess of 35% by weight, the efficacy of alleviating gynecological disease may be good, but the performance of the hydrogel may deteriorate. It is preferable to use within the above-mentioned weight range since there is a phenomenon in which the extract adheres to the skin.

In addition, when the natural adhesive component is used in an amount of less than 5% by weight, the adhesive strength is weak, and when it is used in excess of 10% by weight, the adhesive strength of the skin is strong, causing pain during desorption, so it is preferable to use within the above-mentioned weight range.

The hydrogel is composed of polyhydric alcohol, gelling polymer, hydrophilic polymer, and sodium hydroxide.

Polyhydric alcohol may be glycerin, ethylene glycol, propylene glycol, or a mixture thereof.

As the gelling polymer, agar, carrageenan gum, xanthan gum or a mixture thereof can be used.

As the hydrophilic polymer, gelatin, polyacrylic acid, cellulose, or a mixture thereof can be used.

Sodium hydroxide has a mechanism of dissolving the gel-shaped mugwort hydrogel into a fluid state. Accordingly, when the hot pack is attached to the skin, it responds to the heating temperature of the heating element and melts the gel-shaped mugwort hydrogel to change into a sol state. By doing so, the medicinal ingredient of mugwort plays a role in delivering it to the skin.

The young leaves of wormwood make edible, the leaves make moxa, the stems and leaves are medicinal, and the white hair is used to make manju. It is said that mugwort saves a hundred bottles in [Myeongbyeok-rok], and it is recorded that mugwort heats up and purges cold in [Main Chogangmok]. Efficacy is effective, and it is also effective for neuralgia, cold, anorexia, hepatitis, eczema, etc., and prescriptions for mugwort are Gyoae Gunggwitang, Gyoaesamultang, and Nangungtang.

In addition, mugwort is warm in its properties and is effective for hemorrhagic hemorrhagic disease, menstrual pain, menstrual pain, instability, and abdominal pain.

The efficacy as a medical hot pack can be improved by including wormwood having such an effect in a hydrogel.

There are various types of methods for extracting the active ingredient from the mugwort, such as cold acupuncture method, warm acupuncture method, and hot water extraction method. In the present invention, it is preferable to extract the active ingredient by a hot water extraction method having a wide extraction range. Detailed description is omitted.

Natural adhesive components include ivy sap and starch aqueous solutions, and when ivy sap and starch aqueous solutions are combined, the viscosity of ivy sap is increased to improve the usability and adhesion, and can minimize spoilage. .

Ivy sap can be extracted from the adsorption root of the ivy stem, and the glycoprotein called arabino galactan contained in the sap exhibits adhesion.

The starch aqueous solution may be 10 to 20% by weight of starch relative to 100% by weight of water. This is only a preferred example, and the present invention is not limited thereto.

The natural adhesive component can be prepared by heating the ivy sap at 85° C. for 15 minutes to form a dough using the viscosity of the starch aqueous solution.

After mixing the above-described hydrogel, wormwood extract and natural adhesive components on one surface of the packaging film, it can be solidified to form a mugwort hydrogel layer 30.

By attaching the cover sheet 40 surrounding the outer side of the mugwort hydrogel layer 30, and finally packaging the finished hot pack with plastic wrapper, the inflow of air is blocked to commercialize it.

When using the hot pack, the cover sheet 40 is removed after removing the plastic wrapper, etc., and the mugwort hydrogel layer 30 is directly contacted and attached to the body while the mugwort hydrogel layer 30 is exposed. .

Hereinafter, the present invention will be described in more detail through examples. These examples are only intended to illustrate the present invention more specifically, it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples according to the gist of the present invention. .
