The first carrier 10 has a first surface 11 through which the cosmetic is discharged and the second carrier 20 has a discharge surface 21 through which the cosmetic is discharged to the outside.

The second carrier 20 covers the entire first surface 11 of the first carrier 10. In another embodiment, the second carrier 20 may cover a part of the first surface 11 of the first carrier 10.

The first and second support bodies 10 and 20 are made of a porous material, but the specific materials may be the same or different. The porous material of the porous material may be a foamed foam. Foamed foam is made of NBR (acrylonitrile-butadiene rubber), BR (butadiene rubber), SBR (styrene butadiene rubber), NR (natural rubber), wet urethane, dry urethane, polyether, polyester, polyvinyl chloride, Ethylene Vinyl Acetate), silicone, silicone elastomer, and the like, but is not limited thereto. The foamed foam may be foamed by a dry or wet foamed method, and the foamed foam may contain a fiber. Natural porous materials may be wool, konjac, sponge, cellulose, bio-cellulose or scoria.

The first carrier 10 and the second carrier 20 may be synthetic or natural fiber materials. Natural fibers include, but are not limited to, cellulose, natural pulp, loofah, ramie, ramie, ayate, agate, algae, bamboo, , Sisal, sisal terry, konjac, TENCEL ^™ fiber fabric (natural antimicrobial tencel fiber made from eucalyptus wood), cotton felt, tencel cotton, manaca hemp (abaca fiber, or at least one of them may be included.

The synthetic fibers include, but are not limited to, nylon, acetate fibers, nylon nonwoven fabrics, and carmillon fibers (synthetic fibers, i.e., acrylic fibers having acrylonitrile CH2 = CH-CN fibers as main constituent components), comfort fibers, And may be composed of at least one of methylene terephthalate fiber, polyethylene, polypropylene, polyacrylate, polyacetate, polyolefin, PLA (polylactic acid), and polylactic acid composite fiber (environmentally biodegradable).

At least one of the first and second supports 10 and 20 may be a polyether-based polyurethane foam.

The first carrier 10 and the second carrier 20 carry a cosmetic material. The cosmetic composition may be in the form of an emulsifiable composition, specifically a water-in-oil (W / O / W) or oil in water type (O / W / O) , A dispersed composition, or specifically an oil-dispersed or water-dispersible composition.

The cosmetic may be, for example, a liquid or solid composition, and in the case of a solid-phase composition, it may comprise a powder composition such as a powder. In addition, the cosmetic composition can be used as a makeup primer composition, a makeup base composition, a foundation composition, a concealer composition, a lip composition, a composition for a lip liner, a composition for an eyebrow, a composition for blusher, a composition for ultraviolet screening agent, and a composition for skin care, but the present invention is not limited thereto.

Cosmetics may contain alcohol to provide a cooling sensation. The inclusion of alcohol may also reduce the preservative content. The alcohol may be, but is not limited to, ethanol. The alcohol content in the cosmetic may be from 1 to 15% by weight, from 3 to 12% by weight or from 5 to 10% by weight.

In another embodiment, the shape of the carrier 1 may be variously modified, such as a rectangular plate, or may be composed of three or more layers.

The carrier 1 is made of a porous material having pores 101 and 201 in which cosmetics are moved and / or received in the first and second carriers 10 and 20, respectively. The carrier pores 101 and 201 have an irregular shape.

The size d2 of the pores 201 of the second carrier 20 is smaller than the size d1 of the pores 101 of the first carrier 10 in the carrier 1 according to the present invention. The size d2 of the pores 201 of the second carrier 20 is 0.01 to 0.4 times or 0.02 to 0.2 times the size d1 of the pores 101 of the first carrier 10, .

The size (d2) of the pores 201 of the second carrier 10 may be 1 to 100 μm, 5 to 90 μm, or 10 to 80 μm, depending on the original color of the cosmetic, Can be determined.

In this specification, the volume of the empty space is determined by the size of each of the pores 101, 201 of the carrier 1. For example, when the voids of the second carrier 20 and the first carrier 10 are compared with each other in the same volume, Can be 10 to 30% of the space.

The thickness h2 of the second carrier 20 may be 0.01 to 0.3 times, 0.03 to 0.25 times or 0.05 to 0.2 times the thickness h1 of the first carrier 10. The specific thickness is determined in consideration of the original color of the cosmetic, the color of the user's appeal, the color of the carrier, the amount of the cosmetic, and the size of the pores 101 and 201 formed in the first and second supports 1 and 20 .

If the thickness h2 of the second carrier 20 is less than 0.01 times the thickness h1 of the first carrier 10, the function of implementing the color of the carrier 1 of the carrier 1 according to the present invention can not be achieved, The amount of the cosmetic material to be carried may decrease, and the release of the cosmetic material may become difficult.

The second carrier 20 has a plurality of through holes 203 through which the cosmetic can pass. The through hole 203 serves to discharge the cosmetic material transferred from the first carrier 10 to the second carrier 20 to the outside of the discharge surface 21. That is, the through hole 203 solves the problem that the cosmetic may not be discharged to the outside due to the small pores 201 of the second carrier 20.

The through hole 203 is not limited to being formed only on the second support body 20, but may be formed extending inside the first support body 10. The cross-sectional shape of the through hole 203 is not limited to a circular shape, but may be formed in various shapes such as an elliptical shape.

The size d3 of the through hole 203 is 1.2 to 50 times, 2 to 40 times, 5 to 40 times, or 8 to 35 times larger than the size (d2) of the pores 201 of the second carrier 20 But the present invention is not limited thereto, and they may be provided in different sizes.

The distance l1 between the through holes 203 may be 500 袖 m to 1500 袖 m, 600 袖 m to 1300 袖 m, or 700 袖 m to 1900 袖 m. The size d3 and the distance l1 of the through hole 203 are variously formed according to the viscosity of the cosmetic material, the discharge amount of the cosmetic material, the shape and size of the through hole 203 and the design to be formed in the through hole 203 .

The through hole 203 may be formed by at least one of needle punching, knife cutting, and laser, but is not limited thereto.

The carrier 1 according to the present invention may have a dE * ab value of the color difference between the discharge surface 21 and the cosmetic material in the range of 0.1 to 5.0 when the cosmetic material is carried on the carrier 1. For example, the dE * ab value of the colorimeter may be at least 0.1, at least 0.3, at least 0.5, at least 0.7, at least 0.9, at least 1.1, at least 1.3, at least 1.5, Less than 4.5, less than 4.0, less than 3.5, less than 3.0, less than 2.5, less than 2.0.

The dE * ab value of the colorimetric system is in the range of 0.1 to 5.0, which means that the difference in hue between the color of the carrier 1 carrying the cosmetic and the color of the cosmetic is not large. Accordingly, the coloring of the cosmetic material of the carrier 1 according to the present invention is improved compared with the conventional carrier, and the problem that the carrier 1 is darker than the original color of the cosmetic material when the cosmetic material is carried can be reduced. In addition, there is an effect that the user can grasp the color of the cosmetic product more easily with only the naked eye without applying the cosmetic material carried on the carrier 1.

In the support 1 according to the present invention, the first support 10 and the second support 20 may be adhered. Adhesion may be made partly on the first carrier 10 and / or the second carrier 20, for example around the periphery of the first carrier 10.

When the adhesive is adhered using an adhesive, the adhesive may be at least one of urethane, acrylic, cellulose, low-molecular PE, and PLA, but is not limited thereto.

The first carrier 10 and the second carrier 20 can be adhered and thermally fused without using an adhesive

Fig. 5 shows a second embodiment of the carrier 1 according to the present invention.

In the second embodiment shown in FIG. 5, the plurality of through holes 203 are formed in a diamond shape. In other embodiments, the through-holes 203 may be formed in a variety of spacings, locations, shapes, etc., and the through-holes 203 may implement a desired logo or pattern. Therefore, the through holes 203 can control the amount of the cosmetic material carried on the carrier 1, and can provide visual differentiation compared to the conventional carrier.

The supporting body 1 according to the present invention can provide a coloring effect of the cosmetic material due to the second supporting body 20 having a smaller size d2 of the pores 201 while securing the amount of the cosmetic material carried through the first supporting body 10 There is an effect that can be improved. The carrier 1 having various designs can be formed according to the shape, arrangement, and the like of the through-holes 203 while effectively discharging the cosmetic to the outside by the through-holes 203 formed in the second carrier 20 have.
