Hereinafter, a hot pack to which the 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 to which mugwort hydrogel is applied according to an embodiment of the present invention.

The present invention encloses a heating element 20 that generates heat by an exothermic reaction inside the packaging film 10, wherein the packaging film includes a nonwoven fabric 10a and a breathable film 10b attached to the nonwoven fabric. In the present invention, a mugwort hydrogel is applied to the skin by applying mugwort hydrogel on one surface of the packaging film 10 to provide a hot pack.

The hot pack to which mugwort hydrogel is applied according to an embodiment of the present invention is composed of a heating element 20 and a packaging film 10 encapsulating the heating element 20, and the packaging film 10 is a nonwoven fabric 10a, Including a breathable film (10b) attached to the outside of the nonwoven fabric (10a), and wrapping the outer surface of the mugwort hydrogel and the mugwort hydrogel on one surface of the packaging film (10b), preferably the breathable film (10) It may further include a cover sheet 40 and the like.

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

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

The nonwoven fabric 10a is a fabric made by mechanically treating the fibers so that they are entangled with each other, and has a soft touch, good texture, and excellent tensile strength.

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

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

Polyethylene, polypropylene resin, etc. may be used as the base resin. 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. . When metallocene polyethylene (m-LLDPE) is used, air permeability can be easily controlled during stretching, and the content 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, and the like may be used.

On the other hand, the nonwoven fabric can be laminated to the stretched breathable film using a hot melt or liquid adhesive or embossed to laminate the breathable film and the nonwoven fabric, and the nonwoven fabric and the breathable film are separately produced and laminated. 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 laminated film on a rolling roll.

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

Oxidation: Fe → Fe ²⁺ 2e ^-

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

Fe ²⁺ made in the oxidation zone moves to the reduction zone 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, external air enters the inside of the hot pack, causing an overall oxidation/reduction reaction, and iron powder (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 ㎡/kg, and the ratio of iron powder to the total heating element may be 30 to 90% by weight. If the content of iron is too low, there is a problem that the heating temperature is low or the duration of heat generation is short, and if the content of iron 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 when 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 serving as a passage for electrons is required, and for this, an electrolyte such as sodium chloride, calcium chloride, potassium chloride, magnesium chloride, etc. may be used.

The mass ratio of the electrolyte to the total heating element is preferably about 0.1 to 10% by weight, but may exceed the above range.

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

Since vermiculite has an excellent energy absorption effect, it effectively absorbs heat generated from iron and plays a role in sustaining the heating effect.

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

The mugwort hydrogel contains 50-60% of a hydrogel, 30-35% by weight of mugwort extract, and 5-10% by weight of a natural adhesive component, and the natural adhesive component includes ivy sap and an aqueous starch solution.

On the other hand, if the mugwort extract is used in an amount of less than 30% by weight, the gynecological disease alleviation effect is insignificant, and if it is used in excess of 35% by weight, the gynecological disease alleviation effect may be good, but the performance of the hydrogel may be deteriorated. It is preferable to use the extract within the above-described weight range since there is a phenomenon in which the extract is stained on the skin.

In addition, if the natural adhesive component is used in less than 5% by weight, the adhesive strength is weak, and if it is used in excess of 10% by weight, the skin adhesion is strong and causes pain during detachment, so it is preferable to use it within the aforementioned weight range.

Hydrogel is composed of polyhydric alcohol, gelled polymer, hydrophilic polymer, and sodium hydroxide.

As the polyhydric alcohol, glycerin, ethylene glycol, propylene glycol, or a mixture thereof may be used.

As the gelled polymer, agar, carrageenan gum, xanthan gum, or a mixture thereof may be used.

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

Sodium hydroxide melts the gelatinous mugwort hydrogel and changes it into a fluid state.Therefore, when a hot pack is attached to the skin, it responds to the heating temperature of the heating element and dissolves the gelatinous mugwort hydrogel and changes to a sol state. By doing this, it plays a role in allowing the medicinal ingredients of mugwort to be well delivered to the skin.

Young leaves of mugwort are edible, leaves are used to make moxa, stems and leaves are used for medicinal purposes, and white hairs are used to make inju. In [Myungbyeolrok], it is said that mugwort saves white disease, and in [Bonchogangmok] it is recorded that mugwort heats the inside and removes it by chasing cold. It is effective for neuralgia, colds, loss of appetite, hepatitis, and eczema, and it is recorded that mugwort is commonly used in prescriptions such as Kyoae Gungguitang, Gyoaesamultang, and Nangoongtang.

In addition, mugwort is warm in its properties, so it is effective in hemorrhagic disease, menstrual pain, lunar joint relief, fetal anxiety, abdominal pain, etc.

By including mugwort having such an effect in the hydrogel, the efficacy as a medical hot pack can be improved.

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

Natural adhesive ingredients include ivy sap and aqueous starch solution, and when the ivy sap and starch aqueous solution are combined, the viscosity of the ivy sap increases, so that the feeling of use and adhesion can be improved, and the perishability can be minimized. .

Ivy sap can be extracted from the adsorbed roots of ivy stems, and a glycoprotein called arabino galactan contained in the sap shows adhesion.

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

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

The hydrogel, mugwort extract, and natural adhesive components as described above are mixed and applied to one surface of the packaging film and then coagulated to form the mugwort hydrogel layer 30.

A cover sheet 40 surrounding the outside of the mugwort hydrogel layer 30 is attached, and the finished hot pack is finally wrapped in a plastic wrapper, thereby blocking the inflow of air to commercialize it.

When using the hot pack, remove the plastic wrapper, etc., and then remove the cover sheet 40 to expose the mugwort hydrogel layer 30 and attach the mugwort hydrogel layer 30 directly to the body. .

Hereinafter, the present invention will be described in more detail through examples. These examples are only for describing the present invention in more detail, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not limited by these examples according to the gist of the present invention. .
