Sheet mask pack using thermal sensation [0002]

More particularly, the present invention relates to a sheet mask pack using a thermal sensation, and more particularly, to a sheet mask pack using a heat sensation, and more particularly, to a sheet mask pack using a dual structure having a water- The present invention relates to a sheet mask pack for promoting skin absorption of skin cosmetic ingredients by making the skin flexible by vapor effect of evaporating moisture of gel, thereby improving the skin care effect such as moisturizing, wrinkle improvement, whitening, slimming, .

Generally, in the field of cosmetics, the sheet mask pack is a product that can obtain a moisturizing and cleansing effect by attaching a sheet type manufactured in the form of a face without needing to be worn by hand. It is a sheet of a design capable of covering the entire face, A sheet divided into two sheets, a sheet suitable for a specific area such as an under eye, an eye area, and a mouth, and the like.

Although the sheet mask pack type is recognized as a type in which the efficacy is enhanced by occlusive effect by a nonwoven fabric or a support as compared with general skin care products, various attempts have been made to further enhance the cosmetic effect, The method is a representative example. In the above example, a method of embedding heat ray inside a silicon material and generating heat by connecting a power source (Korean Patent Publication No. 2003-0045384) or a mixture of carbon (C) -aluminum (Al) (JP-A-2004-0073928). However, it is difficult to uniformly arrange the heat rays at a desired position during the manufacture of the mask, There is a disadvantage that an area heating element can not be easily formed. There is a study of a mask (Korean Patent Laid-Open Publication No. 2008-0067423) in which a pre-manufactured surface heating element is attached to a soft silicon mask with a double-sided adhesive silicone tape and a power source is supplied from the outside to provide a thermal sensation. However, There is a disadvantage in that it is difficult to freely change the heat generating position so that the effective ingredient can not be separately supplied and that only the desired position of the face can be heated. In addition, there have been attempts to enhance the cosmetic effect by making the sensation of heat exerted on the outside separately from the sheet mask pack wetted with the emulsion. For example, heat generated during the crystallization process of the sodium acetate supersaturation solution is used as a heating element, (Korean Patent Laid-Open Publication No. 2008-0093572) has been proposed. However, it has been disadvantageous in that it is difficult to stabilize during manufacture and that the mask pack is too thick and troublesome to use.

In the utility model (2010-0003114), the water-based gel mask and the planar heating element are integrally formed, whereas the present invention uses the heating mask having the planar heating element separate from the aqueous gel mask. The mask pack according to the utility model 2010-0003114 has an advantage that it is solved by one mask, but each mask pack includes the surface heating element, so that the unit price of the individual mask pack is high and the surface heating element is applied to the non- It is disadvantageous in that it is limited to a closed type nonwoven fabric (a structure in which the water-based gel is blocked from the back surface or has a thick structure) to apply the water-based gel. On the other hand, the mask pack according to the present invention is composed of a heating mask (including a surface heating element) to be used in a stationary form and an aqueous gel to be used as a consumable article. It may be troublesome to use the mask in two steps. However, In addition to the purchase cost, there is an advantage in that the price of each individual aqueous gel is reduced, and there is another advantage that the applicable aqueous gel is not limited. That is, the present invention is applicable not only to a water-based gel having a thick nonwoven fabric as a support but also to a water-based gel using a mesh-like mesh sachet, a paper-based gel, and a thin support such as a polyurethane (PU) or a silicone film. In addition, since the face mask is additionally fixed to the face using a heating mask, a non-sticky aqueous gel can be utilized.

Accordingly, the present inventors have conducted intensive research to solve the above problems. As a result, the present inventors have found that a water-based gel mask pack for supplying water for softening the skin attached to a desired skin region, And a heating mask for imparting a steam effect by evaporating moisture of the aqueous gel. The flexible printed circuit board (FPCB), which has been previously manufactured to facilitate the production of a heating mask, is embedded in a silicone or rubber material Face type, and power is supplied from the outside, thereby completing the present invention.

Accordingly, it is an object of the present invention to provide a sheet mask pack in which the effect of skin beauty is enhanced, such as moisturizing, wrinkle improvement, whitening, slimming, and elasticity improvement, by promoting skin absorption of an effective ingredient by imparting a thermal sensation.

The present invention provides a sheet mask pack comprising an aqueous gel, a heating mask with a flexible printed circuit board (FPCB) embedded therein, and an external power supply, wherein the skin cosmetic ingredient is contained in the preceding emulsion or the aqueous gel.

The present invention relates to a water-based gel which is composed of a water-based gel mask, a heating mask and an external power source to give a feeling of warmth to the skin and to soften the skin by the vapor effect of evaporating moisture of the aqueous gel, It is possible to provide a cosmetic effect. The exothermic mask of the present invention has an advantage that the price of each individual aqueous gel is low in addition to the initial purchase cost, and there is another advantage that there is no restriction on the applicable aqueous gel. That is, the present invention is applicable not only to a water-based gel having a thick nonwoven fabric as a support but also to a water-based gel using a mesh-type mesh sachet, a paper-based gel and a thin support such as a polyurethane (PU) or silicone film. In addition, since the face mask is additionally fixed to the face using a heating mask, a non-sticky aqueous gel can be utilized.

Hereinafter, the present invention will be described in more detail.

The sheet mask pack according to the present invention is a sheet mask pack which is adhered to a desired skin area and is separately laminated on the outside of a water-based gel and a water-based gel to supply moisture for softening the skin, thereby giving a feeling of warmth to the skin and evaporating moisture of the water- And an external power supply unit. Fig. 1 shows the entire structure of the sheet mask pack using the thermal feeling of the present invention.

The skin cosmetic ingredients of the present invention may be contained within the preceding emulsion or aqueous gel prior to use of the aqueous gel, as shown in Fig.

The skin cosmetic ingredients used in the present invention are all effective ingredients used in the cosmetics field such as moisturizing, wrinkle improving, whitening, slimming, and improving elasticity, and the kind thereof is not limited. Specific examples of effective components for improving wrinkles selected from the group consisting of retinol, retinyl palmitate, adenosine, and polyethoxylated retinamide; A whitening effective ingredient selected from the group consisting of arbutin, mulberry extract, licorice, ethyl ascorbic acid, ascorbyl glucoside, and magnesium ascorbyl phosphate; A moisturizing effective ingredient selected from the group consisting of skimmed mushroom polysaccharide, niacinamide, N-acetylglucosamine; Ivory extract, fancy extract, chamomile, and soybean extract.

The aqueous gel used in the present invention can be applied to most formulations of non-adhesive type aqueous gels and adhesive type aqueous gels, which are general aqueous cosmetic gel formulations, and the formulations thereof are not particularly limited. Examples of the aqueous gel usable in the present invention include a non-woven fabric, a mesh-type mussel, a sticky aqueous gel using a paper, a polyurethane or a silicone film as a support, or a non-sticky aqueous gel.

Preferably, the water content in the aqueous gel formulation is from 40 to 99% by weight based on the total weight of the aqueous gel. If the moisture content exceeds 99 wt%, it is difficult to produce an aqueous gel formulation. If the water content is less than 40 wt%, the effect of generating heat due to heat is insignificant. Aqueous gels are more effective because the higher the water formulation, the more steam is generated by the heat.

The heat-generating mask of the present invention includes a flexible printed circuit board (FPCB) preliminarily fabricated of a surface heating element, which is embedded in a silicon or rubber mask to form a face, and supplies power from the outside.

The flexible printed circuit board used in the present invention is a type of a printed circuit board (PCB), and a printed circuit board is a printed circuit board which is formed by connecting various electronic components to a printed circuit board according to the circuit design of the electric wiring, It is a key part. In view of the beauty of the printed circuit board, there is an advantage in that a circuit design can be freely designed for a target region and a target temperature for each region to make a printed circuit for a cosmetic effect used in the present invention. The flexible printed circuit board (FPCB) used in the present invention is a flexible printed circuit board (FPCB) used in the present invention, which is different from a rigid printed circuit board in which a copper foil is laminated on a thermosetting resin sheet such as epoxy or phenol, It is more suitable for use in a sheet mask pack.

The exothermic temperature of the planar heating element according to the present invention is suitably from 35 to 50 ° C. If it is less than 35 ° C, it does not feel a thermal feeling and does not have a steam generating effect, and if it is more than 50 ° C, it may cause burns.

Therefore, the present invention adopts the most basic structure of a flexible printed circuit board (FPCB) and applies to the present invention. The flexible printed circuit board (FPCB) Is made into a plane heating element and inserted into a mask made of silicone or rubber to produce a heating mask. In Examples 1 and 2 shown in Figs. 3 to 4, polyimide films are also present on portions other than the portions to which the lead wires are applied, but the application regions of the polyimide films may be limited to only portions having copper foil (copper wire). The (+) and (-) poles of the flexible printed circuit board (FPCB) are terminal-treated for connection to an external power supply unit. In this case, (Example 1 of FIG. 4) or a jaw region (Example 2 of FIG. 4).

The heat-generating mask used in the present invention is formed by designing a face shape using silicon or rubber as a main material and inserting a flexible printed circuit board (FPCB) as the surface heating element in the middle. At this time, a terminal attached to the flexible printed circuit board (FPCB) protrudes out of the silicone or rubber material so as to be connected to the external power supply unit as in the third embodiment of FIG. Further, in the present invention, it is possible to provide a belt or the like which can be wound around the back of the head so as to be fixed to the face when using the heating mask.

The heating mask used in the present invention generates heat by receiving power from the outside, and the method is not particularly limited. However, as a preferred example for portability and convenience, it is possible to use a necklace type (Embodiment 4 of FIG. 6) or an attachment type (Embodiment 5 of FIG. 7) directly on a terminal by utilizing an applicator having a rechargeable battery .

Hereinafter, preferred embodiments for facilitating understanding of the present invention will be described. However, the following examples are provided to further illustrate the present invention, and the present invention is not limited to the following examples.
