Description

Cosmetic mask pack {COSMETIC MASK PACK}

The present invention relates to a mask pack.

[Mask Pack]

Skin care for skin moisturizing and cosmetics There are products for direct application such as essence, cream or lotion as cosmetic products. However, since the product for direct application needs to be applied to the local skin area required by the user, it is applied before application It is necessary to wash tools and the like, and when it is desired to apply a sufficient amount of the components because there is a limit in the amount that can be applied in one application, several repetitive application actions are necessary. When a different component is to be further applied, it is necessary to wait for a certain period of time for the first component to penetrate into the skin so that the first component does not wash out and is preferably absorbed into the skin, and then the second component is applied There is a need to do so, and the overall hassle is that this hassle can be simplified and at the same time a considerable amount While the preferred two or more ingredients in skin care enough time to pack the skin can be absorbed itgekkeum (PACK) may be the popularity of the product.

The pack is a skin care beauty product that mainly aims at removal of dead epithelial cell residues and the like, control of fat and sweat secretion, water supply, promotion of skin color, control of body fluids, uniformity of skin elongation, Refers to a product that is attached to an auxiliary tool for a suitable period of time so that nutrients etc. can be absorbed to the skin, as if it has a meaning of covering or covering the root of its origin. Packs are generally used in the form of a film that is dried as it is dried according to the type of the above-mentioned auxiliary tool, etc., and a peel-off type pack is used to remove the film. A pack of a mud type and a sheet of a mask type in which a sheet is moistened on the sheet and covered with the skin.

Among them, the peel-off type pack has a disadvantage that it can irritate the skin when peeling off the film residue, is unsuitable for use on sensitive skin, has a strong binding force between film residue and skin, A pack of a mask type which can expect a comprehensive skin care effect over the whole face of a face has been spotlighted.

[Image Printing Mask Pack]

It is desirable to wear the mask pack in the outdoor space which is a public space as well as indoors, which is a personal space for skin beauty as needed. However, the mask pack should be attached to the face for a sufficient period of time to allow the skin to absorb the nutrients that are soaked in the sheet, so that the third person who is exposed to the sheet in the outdoors is uncomfortable Or awkwardness.

Recently, an idea of printing an image capable of conveying an appeal to the other party on the outer surface of the sheet has been proposed in order to improve recognition. For example, Korean Utility Model Registration No. 20-0470948 discloses a printing method for printing an artist's face image printed on an outer surface of a sheet at a real size, wherein the nutritive component having a moisturizing or whitening effect is made water-soluble and the printing ink is made oil- And the Korean Registered Utility Model No. 20-0475538 discloses a technique of printing durability by printing in the form of stacking images in order to solve problems such as peeling of the printed image on the outer surface of the sheet have.

Korean Utility Model Registration No. 20-0470948 Korean Utility Model Registration No. 20-0475538

When the mask pack is intended to be worn outdoors where activity is required, the mask pack must be able to be fixed to the contact area. For example, if the contact portion is the face portion, the ear can be formed on the seat and the ear can be secured to secure the fixation. For this, the stretchability of the seat is required.

As the sheet of the mask pack, various kinds of textile such as woven fabric, nonwoven fabric or mesh can be used. However, since it is a product that comes in contact with the skin, the texture must be soft, and the nutrients to be supplied to the skin must be impregnated or coated. Therefore, there is a limitation in selecting the fibers constituting the upper textile.

In this connection, in the first generation sheet, a nonwoven fabric blended with rayon and polypropylene was used. Nonwoven fabrics are fibers that are arranged in parallel or in a negative direction without being subjected to a woven fabric process, and then joined together with a synthetic resin adhesive to form a felt. The fibers are entangled to each other and have no advantage in terms of longitudinal and transverse orientation. In addition, rayon and polypropylene are easy to secure materials, and prices are also low.

However, the second-generation sheet used cotton, which was characterized by minimal skin irritation, and absorbency and adhesion were also more favorable than nonwoven fabrics, indicating that synthetic fibers may be somewhat irritating to the skin.

A thermosensitive hydrogel applying a drug delivery material platform as a nutritional ingredient has been developed, and a third generation sheet of a mesh material has been developed which can adequately support it, and has improved adhesion, cooling and absorbency. It was evaluated that the disadvantages of the existing nonwoven fabric and cotton sheet, which were used when the nutrients and the like were flowing down, were improved, which provided considerable convenience.

Recently, bio-cellulose materials classified as fourth generation sheets have been reported to have a merit of being able to contain more than 10 times more nutrients than conventional non-woven fabrics or cotton sheets.

However, some of the upper sheets are not sufficiently stretchable to be able to hang on their ears, and some attempts to print an image on one side of the sheet with some degree of elasticity are not easy, Or the image was peeled off during the stretching process. In addition, some of the sheets did not prevent the ink fired on one side of the sheet from leaching into the nutrients impregnated or coated on one side or both sides of the sheet. All of which can cause irritation to the skin, and thus they are not suitable for the sheet of the mask pack according to the present invention.

Accordingly, the inventor of the present invention has carried out a number of repeated experiments in order to overcome a mask pack which is excellent in stretchability and can be maintained in a state of excellent durability without being damaged when printing an image, and which does not cause skin irritation due to ink , And as a result, finding the specific parameter condition has led to completion of the present invention.

The present invention solves the above problems through the following means.

(1) A mask pack characterized in that the fineness of fibers constituting the sheet is 10-100 denier.

(2) In the above (1), the fibers constituting the sheet are present in a sea-island type, the elongation percentage of the sheet is 400-700%, and the elastic recovery rate of the sheet is 40-85% .

(3) In the above-mentioned (1) or (2), a sheet is used as a support and nutrients are contained on one side of the sheet, and an image is formed on the other side of the sheet at a sublimation temperature of 100-300 ° C Wherein the mask pack has been printed.

(4) The mask pack according to any one of (1) to (3) above, wherein the sheet has an ear-cutting for ear fixing.

(5) The mask pack according to any one of (1) to (4), wherein the sheet can be worn around the ear.

(6) The mask pack according to any one of (1) to (5) above, wherein the nutritional component is a point-adhesive composition.

The mask pack according to the present invention is excellent in stretchability of the sheet, and can be used by being fixed on the ear if the use part is a face part, and is printed on the outer surface of the sheet with excellent durability even when worn from the outside, .

In addition, the mask pack according to the present invention is less irritating to the skin due to the ink used for image printing, and surprisingly, the delivery efficiency of the nutrients and the like to the skin is remarkably superior to that of the conventional products.

Further, even if the mask pack according to the present invention is worn in an active state from the outside, the nutrition component can be preferably absorbed into the skin without flowing down.

1 shows an exemplary form of a mask pack according to the present invention.
2 shows an exemplary wearing of a mask pack according to the present invention.

A mask pack according to the present invention includes an image print unit on one side of a support sheet and nutrients on one side or both sides.

[Justice]

Words representing a single form may include a plurality of objects, unless the context clearly indicates otherwise. For example, the term " nutritional ingredient " means both a single nutritional ingredient and a product containing two or more nutritional ingredients, and " sheet " means both single and multi-layered.

The term " nutritional component " or " nutritional component " refers to a component impregnated or coated on one or both surfaces of a sheet, and in some cases, it represents skin cosmetic ingredients such as essence, , A skin cosmetic ingredient delivery platform such as a hydrogel, and other additives such as solvents and perfumes.

The term "fineness" refers to the final fineness of a yarn other than a single yarn unless specifically indicated otherwise.

The term " image " refers to anything that can be aesthetic, such as being composed of a single color or forming a specific shape.

Other terms denote meanings that can be tolerated by an ordinary technician.

[Support sheet]

Non-woven fabrics have been generally used for the mask pack sheet, but the present invention is not limited thereto, and the use of various textiles such as fabrics or mesh meshes is possible without limitation. However, the selection of the fiber as the raw material of the woven textile is important in achieving the effect according to the present invention.

Examples of the fiber include natural fibers such as cotton, hemp, wool or silk; Regenerated fibers such as rayon or acetate; Synthetic fibers such as nylon, acrylic, polyester or polyurethane; And inorganic fibers such as glass or carbon.

Among them, since the mask pack according to the present invention needs to have good stretchability, it should not be selected that the elastic recovery rate of the above-mentioned fibers is extremely low. The elastic recovery rate is the percentage of the recovery length after the external force is removed by the external force. Although the exact cause can not be grasped by the present inventors, it is preferable to select the fibers so that the elasticity recovery rate of the sheet is 40-85% in order to achieve harmonious expression of all effects desired by the present invention including elasticity. To 45-80% of the total weight of the fibers. Specifically, as a result of the experiment, when the above-mentioned lower limit was not satisfied, the stretchability of the sheet was unsatisfactory, and the sheet could not be evenly adhered to the skin on the jaw line when the ear was worn on the face, In case of failure, the durability of the printed image is somewhat lowered. In addition, the nutrients and the like are not fixed to the sheet preferably, and the water is drained downward over time or discharged into the air, I could not resist.

Further, in order to achieve the desired effect of the present invention, it is necessary to select and process the fibers so that the elongation percentage of the sheet becomes 400-700%. When the above criteria are not satisfied, there is a problem in that the elasticity of the earphone portion tends to be broken when the earphone is worn on the face portion to fix it to the ear portion. If the above criteria are not satisfied, the mask pack tends to be stretched, There was no problem.

Non-limiting examples of fibers that can be processed to achieve the elastic recovery and elongation conditions of the top sheet are polyethylene terephthalate (PET), polyethylene (PE), polyester (PS), aluminum, nylon, polypropylene (PP), Oriented Polypropylene (OPP), Casting Polypropylene CPP, High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Linear Low Density Polyethylene (Linear low density polyethylene, LLDPE), polyvinyl chloride, polyacrylonitrile, polyurethane, polyethersulfone (PES), polyvinylidene fluoride (PVDF), polyetheretherketone (PEEK), polyphenylene sulfide Polymer-based polymers, and the like. At this time, the sheet may be processed by combining one or more fibers.

In addition, since the present invention relates to a mask pack, it is necessary that the nutrients and the like are uniformly contained in the sheet. When the nutrient and the like are applied to the skin, the nutrients and the like need to be effectively absorbed by the skin. Since the present invention is intended to print an image on a sheet, it must be easy to dye and the like, and the condition of the fiber of the known mask pack has to be different.

In this connection, the present inventor has repeated numerous experiments to develop an optimum sheet, and from this, the single yarn fineness of the fibers is 0.1-5 denier and the final fineness is 10-100 denier at the time of processing the fibers, Considering not only the desired effect of the present invention but also the manufacturing cost, it is more preferable that the final fineness is 20-50 denier, and that the structure is a sea-island type. At this time, the seam fiber and the fiber may be made of the same or different fibers.

The present inventors have found that when the fineness does not satisfy the lower limit, the image printing is not easy and the sharpness of the printed image is not satisfactory. Therefore, the present invention can not manufacture the intended mask pack, If the above upper limit is not satisfied, deflection occurs in the fiber array, the texture is not smooth, and there is also a problem in stretchability, and it is likewise impossible to manufacture the intended mask pack of the present invention I found a new fact.

There are side-by-side type, segment type, core-sheath type, or sea type type according to the cross-sectional structure in relation to the processing structure. When the fineness of the fiber is 10-100 denier, It was required to be processed to have excellent stretchability, easiness of dyeing, and impregnation with nutritional ingredients.

The method for producing sea-island fibers can be produced by separately melting a sea component and a component, and then spinning the core component through a nozzle for a composite fiber. As a non-limiting example, a spinning yarn (SDY) process, a highly oriented oriented (HOY) process, a highly oriented yarn process can be selected.

Sheets may take the form of earrings. For example, as shown in FIG. 1, the ear-cut portion exists in an incisional form formed at an angle (X) within 45 degrees with respect to the central axis Y. As shown in FIG. 2, And may be in a wearable form.

[Image printing section]

A variety of designs can be applied to the image printing unit, and a single color body, an animal, a plant, a character, a natural shape, a geometric pattern, or a human face can be considered as non-limiting examples.

When forming the image print portion on the sheet of the mask pack, a known technique can be selected appropriately. For example, a silk screen, a gravure, a digital print or a UV printing method can be used.

However, the ink to be used at this time needs to be selected from a sublimation transfer ink (Dye Seblimation Ink), which is preferable in view of the clarity and durability of an image after printing. Particularly, sublimation transfer is preferably performed at a temperature of 100 to 300 ° C, and sublimation transfer is most preferably performed at a temperature of 150 to 250 ° C. When the sublimation temperature is less than 100 ° C, there is a problem that the ink is not sufficiently dyed on the base sheet and the print is not clear. When the sublimation temperature exceeds 300 ° C, the base sheet is melted due to the high heat required for sublimation There is a problem.

[Nutritional ingredients]

Nutrients and the like generally include all components applicable to mask packs, including water-soluble gels, viscous patches or essence impregnated forms, but in terms of achieving the desired effect of the present invention, desirable. That is, the mask pack in which the image is printed on one surface of the support sheet and the adhesive layer coated on the other surface may be fixed without flowing out of the nutrient components, so that it can be worn during external activities, Even if the mask pack is stretched to fasten the mask pack, it is less likely to crack or leak out to the outside, and particularly in combination with the sheet according to the present invention, the penetration rate of nutrients and the like to the skin It was very good, and the interaction with the image printing department was also small.

The viscous composition may include a hydrophilic polymer, a skin active ingredient, a polyhydric alcohol, a cross-linking agent, and a gelation rate regulator, and may further include other functional additives as needed.

Wherein the adhesive composition comprises 0.5 to 10 wt% of a hydrophilic polymer, 0.01 to 10 wt% of a skin active ingredient, 5 to 35 wt% of a polyhydric alcohol, 0.01 to 5 wt% of a crosslinking agent, 0.05 to 3 wt% of a gelation rate regulator, .

The polyhydric alcohol is included in an amount of 5 to 35% by weight based on the skin-adhesive composition. More preferably 10 to 30% by weight. When the amount of the polyhydric alcohol is 5% by weight or less, moisture in the composition tends to be volatilized and adherence deteriorates at the time of adhering the skin, and when it exceeds 35% by weight, a tacky point occurs and the feeling of use is lowered.

The cross-linking agent is preferably a polyvalent metal salt, and examples thereof include aluminum hydroxide, aluminum hydroxide gel, hydrated aluminum silicate, kaolin, aluminum acetate, aluminum lactate, aluminum stearate, calcium chloride, magnesium chloride, magnesium aluminum metasilicate, And magnesium aluminosilicate. [0033] The term " a "

The crosslinking agent is added in an amount of 0.01 to 5% by weight, preferably 0.05 to 3% by weight, based on the composition of the present invention. When the crosslinking agent is added in an amount of 0.01 wt% or less, the crosslinking reaction does not sufficiently proceed and the strength of the cured composition is insufficient. When the crosslinking agent is added in an amount exceeding 5 wt%, the crosslinking reaction rate becomes too fast and the workability is poor.

The gelling rate regulator may be, for example, an organic acid such as EDTA, acetic acid, lactic acid, oxalic acid, citric acid or tartaric acid having a chelating action with respect to a metal ion, an organic acid salt such as EDTA-2 Na, calcium citrate or sodium citrate, May be at least one selected from the group consisting of
