Description

Technology Field

[0001] The present invention relates to a mask pack and a mask sheet. Background Technology

[0002] Mask packs are a representative home beauty care method widely used because they can conveniently and instantly deliver nutrients and moisture to the skin, such as the face, or remove impurities. Various types of mask packs are sold on the market, varying depending on the material and shape of the mask sheet, the type of cosmetic composition (such as serum) impregnated into the sheet, and the impregnation method. Recently, a wide variety of products have also emerged that apply microcurrents to the mask sheet to further enhance effects such as improving skin elasticity.

[0003] Microcurrent refers to a weak current of less than 1,000 μA, and it is known that microcurrents ranging from approximately 40 μA to 60 μA flow within the human body. This is a chemical reaction within the body that occurs through the continuous exchange of various ions across cell membranes; it is related to fundamental metabolic processes, such as signal transduction, muscle contraction, substance secretion, and stimulus reception, as well as cell growth, regeneration, and healing. In particular, it is known that supplying microcurrents promotes blood circulation by increasing blood flow in capillaries, or increases the synthesis of collagen and elastin through the rise in ATP resulting from the activation of fibroblasts. Accordingly, the cosmetics industry is seeking to develop devices or equipment capable of separately supplying these microcurrents to the skin to further enhance skin condition improvement effects, and the fields and methods of application are becoming increasingly diverse.

[0004] However, existing microcurrent mask packs have had several drawbacks, such as minimal effects due to relying solely on the body's own microcurrents without a separate power supply, reduced user convenience because the separate power device (battery) is large and heavy, or the inability to recharge. Furthermore, regarding the delivery of active ingredients through iontophoresis using microcurrents, it was difficult to deliver specific active ingredients to desired areas with high efficiency because the conductive patterns on the mask sheet were formed simply and uniformly or designed without a consistent direction.

[0005] Against this backdrop, the inventors have developed a microcurrent mask pack comprising an ultra-thin battery, wherein the conductive patterns of different electrodes are separated through pores (gaps), thereby allowing for the directionality of the microcurrent and enhancing the penetration efficiency of specific active ingredients into desired areas. The ultra-thin battery is lightweight and easy to attach to a mask sheet, making it convenient to use. Furthermore, through the microcurrent, it can produce effects such as increased skin elasticity, regeneration of damaged tissues, and improved blood circulation without irritating the skin.

Specific details for implementing the invention

[0012] The present invention will be described in more detail below through the attached drawings and embodiments. However, these drawings and embodiments are for illustrative purposes only and the scope of the present invention is not limited to these embodiments.

[0013] In addition, terms such as "composed" or "comprising" used in these embodiments should not be interpreted as necessarily including all of the various components or steps described in the specification, and should be interpreted as potentially excluding some of the components or steps, or including additional components or steps.

[0014] As illustrated in FIGS. 1 and 5, a microcurrent mask pack (30) according to one aspect comprises a mask sheet (10) having a conductive pattern formed thereon, divided into a first region (11) and a second region (12) by a void portion (16) formed across both ends of the mask sheet; a (+) electrode junction (13) and a (-) electrode junction (14) of an ultra-thin film battery formed on one side of the mask sheet and formed in the first region (11) and the second region (12), respectively; and an ultra-thin film battery (20) attached to the electrode junctions to supply microcurrent. That is, the conductive pattern of the first region and the conductive pattern of the second region are separated from each other by a non-patterning region, which is a region where the conductive pattern is not printed, and are formed to be combined with different electrodes of the ultra-thin film battery.

[0015] The mask sheet (10) can be formed in a circular shape with holes for the eyes, nose, and mouth, similar to the shape of a known mask pack, and the material may be nonwoven fabric (cotton, rayon, lyocell, cupro, silk, microfiber), hydrogel, or (dry) biocellulose, but is not particularly limited thereto.

[0016] A conductive pattern is formed on one side of the mask sheet (10), and this may be designed as a honeycomb or rhombus pattern and printed to completely cover one side of the mask sheet.

[0017] The above conductive pattern is mainly composed of a highly conductive material, specifically, it may be graphene, carbon nanotubes, or conductive metals, and more specifically, it may be graphene oxide (~100 kΩ), carbon nanotubes (~100 kΩ), or silver nano (~100 kΩ), but is not particularly limited thereto.

[0018] The conductive pattern is formed by dividing it into a first region (11) and a second region (12) with respect to a void portion (16) formed across both ends of the mask sheet, and the first region patterns a reduction electrode and the second region patterns an oxidation electrode, respectively. Specifically, the first region may be formed in the upper part based on the void portion, that is, the forehead portion of the mask sheet, and the second region may be formed in the lower part based on the void portion, that is, the eye, nose, mouth, and cheek portions of the mask sheet. A current flow in a certain direction can be imparted by the conductive patterns of the first region (reduction electrode; (+) electrode graphene net; positive electrode) and the second region (oxidation electrode; (-) electrode graphene net; negative electrode) that are divided from each other.

[0019] The conductive pattern includes a first pattern (15) and a second pattern with different densities. Specifically, the pattern excluding the first pattern among the conductive patterns may be the second pattern, and the density of the first pattern is relatively denser than the density of the second pattern. Accordingly, a microcurrent of relatively higher intensity may flow in the first pattern than in the second pattern, and as a result, the penetration efficiency of the active ingredient (anionic or cationic) in the first pattern may be higher. The first pattern may be formed in areas where many wrinkles occur, for example, around the eyes and mouth, nasolabial folds, etc. Accordingly, as shown in FIGS. 1 and 2, the first pattern may be formed in the second region of the conductive pattern, but is not particularly limited thereto.

[0020] In this specification, the term "ultra-thin film battery" refers to a secondary battery made by stacking a positive electrode, a solid electrolyte, and a negative electrode in sequence on a thin substrate, wherein the liquid electrolyte is solidified into a film of ceramic material, thereby eliminating the risk of explosion and having the characteristic of being flexible like paper. In this specification, the term "ultra-thin film battery" may be used interchangeably with "thin film battery."

[0021] According to one aspect, the ultra-thin film battery (20) includes a battery cell (21), a (+) electrode (22), and a (-) electrode (23), and its thickness may be about 0.4 mm or less. As shown in FIG. 1, the (+) electrode is bonded to a (+) electrode junction (13) located in a first region, and the (-) electrode is bonded to a (-) electrode junction (13) located in a second region, and a current flow in a certain direction may be imparted by the conductive pattern of the first region (reduction electrode) and the second region (oxidation electrode) where each electrode is bonded. Specifically, in the microcurrent mask pack, the current flow may be in the direction from the first region to the second region, and this may be in the opposite direction depending on the type of electrode.

[0022] In this specification, the term "microcurrent" refers to a current having an intensity of several to several hundred microamperes (µA), which can generally be described as subsensory level stimulation.

[0023] The intensity of the microcurrent generated by the ultra-thin film battery (20) may be about 200 μA or less. Specifically, in the first pattern, which is a dense current flow section, it may be about 180 μA or less, and in the second pattern, it may be about 120 μA or less.

[0024] According to one aspect, the microcurrent mask pack (30) may additionally include a cosmetic composition. As shown in FIG. 6, the cosmetic composition may be impregnated into the mask sheet (10) to form a layer of the cosmetic composition on at least one side, specifically both sides, of the mask sheet, and the mask sheet (10) and the ultra-thin battery (20) are characterized by being bonded by an adhesive force due to the capillary action of the cosmetic composition layer. Specifically, according to one aspect, the ultra-thin battery has a thickness of about 0.4 mm or less, so it can be bonded to the mask sheet by an adhesive force with the cosmetic composition layer without using adhesive hydrogels or magnets.

[0025] The above cosmetic composition may be manufactured in any formulation conventionally produced in the industry and may be formulated into a solution, suspension, emulsion, paste, gel, cream, lotion, serum, toner, emulsion, surfactant-containing cleansing, oil, etc., and more specifically, may be a serum formulation, but is not particularly limited thereto. In addition, the above cosmetic composition may be manufactured into products such as softening lotion, astringent lotion, nourishing lotion, essence, eye essence, eye cream, nourishing cream, massage cream, cleansing foam, cleansing cream, cleansing oil, cleansing water, hand sanitizer, hand wash, hand scrub, body wash, body scrub, shaving lotion, body lotion, body oil, body mist, body essence, sun cream, etc.

[0026] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
