Therefore, the object of the present invention is that even if the mask sheet is contaminated according to the manufacturing and distribution conditions of the mask sheet packaged in the package, a film providing antibacterial and antiviral functions is peelably attached to one surface of the mask sheet on which the essence is deposited. It is to provide antibacterial and antiviral mask packs that can remove bacteria or viruses.

In addition, another object of the present invention is that a film that provides antibacterial and antiviral functions is attached to one surface of the mask sheet, so that one surface that is in contact with the skin during the process of holding and unfolding the mask sheet can be minimized from contacting the user's hand. It is to provide antibacterial and antiviral mask packs.

On the other hand, the object of the present invention is not limited to the object mentioned above, other objects not mentioned will be clearly understood by those skilled in the art from the following description.

According to the present invention, a mask sheet which has one side in close contact with the user's skin so that the impregnated essence is absorbed into the skin; There is provided an antibacterial and antiviral mask pack comprising an antibacterial and antiviral film in close contact with the mask sheet to sterilize bacteria due to deterioration or contamination of the essence or remove viruses.

Here, the antimicrobial and antiviral film includes a film body that has an area corresponding to the mask sheet and is peelably adhered or adhered to the back surface of the mask sheet, and the film body is a thermoplastic plastic for providing a base film function 95 It is preferably prepared by mixing to 99.5% by weight and 0.5 to 5% by weight of copper having a purity of 85% to 95% for providing antibacterial and antiviral functions.

In addition, the mask sheet is a nonwoven fabric having a polypropylene material or a fabric material that is not irritating to the skin, and it is preferable that the mask sheet is made of 15 g/m2 to 30 g/m2.

In addition, the antibacterial and antiviral film further includes an auxiliary functional layer formed on the film body, and the auxiliary functional layer includes a barrier layer formed by depositing an inorganic oxide on the film body, and an antibacterial and antiviral layer on top of the barrier layer. It is preferable to include an antibacterial and antiviral layer formed by depositing a sexual material.

In addition, as for the barrier layer, the inorganic oxide includes at least one selected from silica, alumina, zirconia, and combinations thereof, and the thickness is preferably 5 nm to 10 nm.

In addition, the antibacterial and antiviral layer has a thickness of 10 nm to 20 nm, and contains 100 parts by weight of silver nano, 70 to 90 parts by weight of germanium, 50 to 70 parts by weight of selenium, 30 to 50 parts by weight of zinc, and 3 to 5 parts by weight of triclosan It is desirable to do.

Therefore, according to the present invention, as a film that provides antibacterial and antiviral functions is attached to one side of the mask sheet, the essence of the mask sheet is deteriorated by the film, or even if bacteria are proliferated or viruses are infiltrated during the mask pack. It can provide antibacterial and antiviral functions to eliminate.

On the other hand, the effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The antibacterial and antiviral mask pack according to the present invention includes a mask sheet that has one side in close contact with the skin such as a user's face to allow the impregnated essence to be absorbed into the skin, and a peelable attachment on the back side of the mask sheet so as to deteriorate the essence. Or antibacterial and antiviral films that sterilize or sterilize bacteria or remove viruses from contamination.

The mask sheet is preferably a non-woven fabric having a shape such as a mask corresponding to the shape of the face and having a polypropylene material or a fabric material that is not irritating to the skin.

Here, the polypropylene is a thermoplastic resin obtained by polymerizing propylene, has an isotactic structure, and has a structure in which methyl groups are arranged in the same direction, and is one of the four major plastics along with polyethylene, polyvinyl chloride and polystyrene, and has a specific gravity of 0.82 It is the lightest plastic in the range of 0.92 to 0.92 and has a high softening point and easy processing.

The mask sheet has an areal density of 15g/m2 to 30g/m2.If the areal density is less than 15g/m2, there is a problem that the essence is volatilized in a short time due to the low density, and if it exceeds 30g/m2, it is a nonwoven fabric. Due to the high density of the skin, it is not absorbed into the corresponding part of the skin and there is a problem in that the impregnated state is maintained inside the nonwoven fabric, so it is preferable to have the above areal density.

Here, the mask sheet can be mask-packed on the skin in a state where the antibacterial and antiviral films are attached to the back surface by the tension of the essence, so even if the surface density is about 15g/m2 to 30g/m2 as described above, the film As a result, the essence is not easily volatilized, and thus, the thickness of the mask sheet can be reduced, and through this, the manufacturing cost can be reduced.

On the other hand, the essence is a cosmetic product in which an active ingredient that nourishes the skin is highly concentrated, and it is preferable to have low fluidity through a predetermined viscosity.

As an example, the essence is dissolved in a solvent having a degree of deacetylation (DA) within the range of 80 to 100% and a pH within the range of 3.5 to 7.5 at a dissolution rate within the range of 1 to 15 minutes. It contains various fast-dissolving substances and solvents.

Antibacterial and antiviral films are peelably attached to the back surface of the mask sheet, and are a means to sterilize or sterilize bacteria or remove viruses due to deterioration or contamination of the essence, and have an area corresponding to the mask sheet and have a thickness that can be modified in shape. It is preferable that it is a film body which has a peelable adhesion or adheres to the back surface of the mask sheet using the tension of the essence.

The film body may be prepared by mixing 80 to 90% by weight of a thermoplastic plastic for providing a base film function and 0.5 to 5% by weight of copper having a purity of 95% to 99.5% for providing an antibacterial and antiviral function.

Here, the thermoplastic plastic is preferably at least one of PE, OPP, PVC, PO, and PS.

In addition, copper is intended to provide antibacterial and antiviral functions, and has a purity of 85% to 95%, but when it has a purity of less than 85%, the antibacterial and antiviral functions are greatly reduced over time and 95% If the purity is exceeded, the antibacterial and antiviral functions do not change over time, but the melting process is complicated and the manufacturing cost is high, so it is good to have a critical significance according to the above numerical limitation.

In addition, copper is mixed in an amount of 0.5 to 5% by weight based on 100% by weight of the total weight% of the thermoplastic plastic in the manufacture of the film body, but when the amount of copper is less than 0.5% by weight, antibacterial and antiviral If the function is deteriorated and the amount of copper added exceeds 5% by weight, there is a problem in that manufacturability such as the elongation of the thermoplastic plastics providing the base film function is deteriorated, so the critical significance according to the numerical limitation as described above. It is good to have.

Therefore, according to the antibacterial and antiviral film, a film body in which copper and thermoplastic plastic are mixed is produced, and one side of the mask sheet is in contact with the film body, so that a composition for antibacterial is formed on one side that is in contact with the mask sheet. It suppresses the deterioration of the essence and can sterilize or sterilize bacteria or infiltrated viruses that have grown during deterioration or use.

On the other hand, the antibacterial and antiviral film of the present invention is composed of a method such as deposition, application, or spray coating on one surface of the film body manufactured as described above, and is present in the essence of the mask sheet when in close contact with or attached to the back surface of the mask sheet. It may further include an auxiliary functional layer for sterilizing or sterilizing harmful bacteria or removing viruses.

The auxiliary functional layer is to provide a function of sterilizing or sterilizing bacteria or removing viruses present on at least one of the one side and the other side of the film body due to deterioration of the essence of the mask sheet. It includes a barrier layer formed by deposition, and an antibacterial and antiviral layer formed by depositing an antibacterial and antiviral material on an upper portion of the barrier layer.

The barrier layer is formed of a transparent dense film of inorganic oxide to provide a catalytic function and absorb radiant energy from a light source, so that the antibacterial and antiviral functions of the mask sheet described later are maximized. The oxide includes at least one selected from silica, alumina, zirconia, and combinations thereof, and preferably has a thickness of 5 nm to 10 nm.

Here, when the thickness of the barrier layer is less than 5 nm, the antibacterial and antiviral functions are deteriorated, and when the thickness exceeds 10 nm, the film body changes according to the shape deformation of the mask sheet. It is good to have critical significance by.

Meanwhile, in the present invention, when a barrier layer is formed on the film body to provide a catalytic function from a light source, etc., in the film body, a diffusion block protrudes to allow light transmitted through the barrier layer to diffuse widely toward the skin. It is good to be formed.

Here, the diffusion block may have a structure in which a plurality of convex bands gradually have a large diameter, such as a ring shape, and are continuously arranged, and light transmitted from one side or surface of the film body toward the skin has a circular ring shape. It is better to make it light-transmitting.

In addition, when the film body has a predetermined thickness, it is preferable that bubbles of a predetermined size for scattering light are formed therein by foam molding such as foam extrusion or foam injection during manufacture of the film body.

The antibacterial and antiviral layer is formed as a dense film to provide an antibacterial function, and includes silver nano, germanium, selenium, zinc and triclosan, and preferably has a thickness of 10 nm to 20 nm.

Here, when the thickness of the antibacterial and antiviral layer is less than 10 nm, the composition of the metal component is not formed as a film, so it cannot have sufficient reactivity, and when it exceeds 20 nm, it requires a lot of processing time as well as the thickness of the film body. The film body is lifted when the mask sheet adheres to the skin without peeling the film body due to a problem that the film body is lifted when the film body is not peeled off due to the thickening of the mask sheet. It is good to have.

In addition, the antibacterial and antiviral layer contains 100 parts by weight of silver nano, 70 to 90 parts by weight of germanium, 50 to 70 parts by weight of selenium, 30 to 50 parts by weight of zinc, 3 to 5 parts by weight of triclosan, and the like.

The silver nano is used to sterilize bacteria or remove infiltrating viruses due to deterioration of the essence during the mask pack process using a mask sheet, and it is preferable to have nanoparticles.

Germanium is for enhancing immunity by radiating far-infrared rays in a place close to the skin in addition to the function of sterilizing and removing viruses from a mask facsimile using a mask sheet, and 70 to 90 parts by weight are added and mixed with respect to 100 parts by weight of silver nano If the amount is less than part by weight, the function of sterilization or virus removal and immunity is deteriorated, and if it exceeds 90 parts by weight, the essence is easily deteriorated with the heat of the skin due to predetermined heat during the massage pack process. It is good to have critical significance by.

Selenium is for suppressing damage and aging of skin cells by removing active oxygen in a mask facsimile using a mask sheet, and 50 to 70 parts by weight are added and mixed with respect to 100 parts by weight of silver nano, but less than 50 parts by weight In the case where the active oxygen removal function is deteriorated, and when it exceeds 70 parts by weight, the pores are expanded during the massage pack process to cause hair loss, so it is good to have a critical significance by limiting the parts by weight as described above.

Zinc is to provide functions such as antibacterial, antiviral, and anti-inflammatory in a mask facsimile using a mask sheet, and 30 to 50 parts by weight are added and mixed with respect to 100 parts by weight of silver nano, but if it is less than 30 parts by weight, If the antibacterial and anti-inflammatory functions are deteriorated, and if it exceeds 50 parts by weight, the sterilization and sterilization functions of copper contained in the film body are rather offset, so it is good to have a critical significance by limiting the parts by weight as described above.

Triclosan is to provide antibacterial function of mask facsimile using a mask sheet, and 3 to 5 parts by weight are added and mixed with respect to 100 parts by weight of silver nano, but if it is less than 3 parts by weight, the antibacterial function is lowered and The effect of suppressing the occurrence of fungi or mold due to deterioration of the skin due to the skin temperature, etc. is reduced, and if it exceeds 5 parts by weight, there is a problem that the lotion is turned into a carcinogen during long time use according to the reaction with other substances. It is good to have a critical significance by limiting parts by weight as described above.

Therefore, according to the auxiliary functional layer, as the composition for antibacterial and antiviral contacting the mask sheet is formed, it is possible to suppress the deterioration of the essence during distribution of the mask sheet, and to remove bacteria or infiltrating viruses that have proliferated during deterioration or use. .
