As for the conventional technology for forming double eyelids, the adhesive sheet for forming double eyelids is applied to the eyelids, and the skin of the eyelids is pulled by hand and lifted up to adhere and fix (the following patents) Reference 1).
Alternatively, the brush tip is a brush, and the adhesive liquid is stored in advance on the brush tip and applied to a flat surface on the skin, and then adhered while being pushed in with the attached stick-bar-like instrument, or the adhesive liquid is a nail polish container In addition, a plastic stick attached to the cap of the nail polish container and applied to the skin with a plastic brush and then pressed and adhered with a separately attached stick bar-like instrument (see Non-Patent Document 1 below) is also known. .

JP 2003-102546 A Product name: Royal Aim http://www.royalkaken.com

Here, in the conventional adhesive tape application type or liquid application type instrument (hereinafter referred to as the conventional application tool) to the brush tip of the liquid, both are applied to the eyelid push-in instrument after application or after application. It is necessary to quickly carry out eyelid joining work by holding, etc., and if it takes time, there is a problem that the adhesive strength decreases due to drying of the adhesive liquid or the expected adhesive strength does not occur after drying It was. Furthermore, the skin of the eyelid at the site where the adhesive liquid has been applied is pushed in from above with an indenter, but at this time, the adhesive liquid and the indenter are adhered, and the joint is broken when removed. . Also, as a result of rushing the work, there was a problem that the formation of the required double eyelid failed due to an erroneous eyelid attachment position. Therefore, it is necessary for the user to apply an adhesive liquid that is highly viscous and difficult to dry, and it was necessary to hold the eyelids until the adhesive liquid dried and the eyelids were fixed. There were problems that formation of a double eyelid could not be easily performed because it took a plurality of instruments, time and great effort to form.

On the other hand, even if the double eyelid is completed, the shape tends to be single, and there is a problem that the double eyelid having a shape according to individual preference cannot be formed.

In addition, in the conventional applicator, the adhesive liquid at the tip of the brush gradually decreases from the start of application to the end of application. There was a problem of unevenness. In order to prevent such scumming, it was necessary to add more adhesive liquid to the brush tip than is necessary for joining, or to apply the adhesive liquid twice, but the extra adhesive liquid would protrude from the eyelids. Due to the unevenness of the amount applied, the appearance is not good because it is exposed when the eyelids are opened and closed, or the cosmetic is thickly applied to the joint when applying makeup and going out etc. There was a problem. Since the double eyelids are not formed uniformly and become an unnatural uneven double eyelid, there was a problem that the double eyelids envisioned by myself could not be formed. Furthermore, once the brush brush tip is used, the adhesive solution hardens the next day, and there is a problem that it cannot be used as it is unless it is immersed in an alcohol solution.

On the other hand, since a large amount of adhesive liquid forms a thick film, if the eyelid formation fails or the eyelid peels off, remove the thick adhesive liquid once. Therefore, it was necessary to restart the troublesome formation work from the beginning.

In view of the above-mentioned problems, the object of the present invention is gentle on the eyelid skin, ensures the reliability and simplicity of the formation of the double eyelid, and integrates the applicator and the forming tool. An object of the present invention is to provide a forming tool capable of forming a heavy eyelid and a method for forming a double eyelid.

In order to achieve the above-mentioned object, the invention according to claim 1 is a liquid storage container having an adhesive liquid stored therein, a rear end portion of which is in contact with the adhesive liquid in the container, and a tip end portion of which is outside the container. A porous structure utilizing capillary action that is held in a protruding shape (including those fixed to the liquid storage container so that it cannot be removed for holding or those that can be inserted into and removed from the liquid storage container; the same applies hereinafter) The liquid supply member is provided.

According to claim 2, in the double eyelid forming tool according to claim 1, the liquid supply member having the porous structure is a natural fiber, a polyacetal resin, an acrylic resin, a polyester resin, a polyamide resin, or a polyurethane resin. A porous structure (including fiber bundles or foams; the same applies hereinafter) by any one or combination of resins, polyolefin resins, polyvinyl resins, polycarbonate resins, polyether resins, and polyphenylene resins. The formed adhesive liquid is characterized by containing, as an adhesive component, a polymer having any one of water solubility, lower alcohol solubility, and water / lower alcohol mixture.

According to a third aspect of the present invention, in the double eyelid forming tool according to the first or second aspect, the liquid supply member is formed in a rod shape that can be inserted into and removed from the liquid storage container.

According to a fourth aspect of the present invention, in the double eyelid forming tool according to the third aspect of the present invention, the liquid supply member is formed in different shapes at both ends.

Moreover, in the double eyelid formation method which concerns on Claim 5, it is a method of forming a double eyelid using the double eyelid formation tool in any one of Claims 1-4, Comprising: A liquid storage container is used. Glue the liquid supply member against the epithelium of the eyelid by holding it with your finger and apply it to the skin pressed by the liquid supply member when creating a crease while moving it from the inside to the outside along the eye contour. It is attached and the folding wrinkle formed in the pushed state is hold | maintained, It is characterized by the above-mentioned.

According to the first aspect of the present invention, the liquid supply member having a porous structure is held in a state where the adhesive liquid is always supplied by capillary action. Further, if necessary, the liquid storage container may be made of a plastic pressure type, so that the container is pressed with a finger to pressurize the adhesive and be fed to the liquid supply member. For this reason, when the double eyelid forming tool according to the present invention is used, the liquid supply member is pressed against the skin where the double eyelid is to be formed, and is moved from the inside to the outside along the eye contour. A double eyelid can be formed instantaneously by a process of making a fold wrinkle and applying the adhesive liquid to the pressed skin as needed and holding the fold wrinkle formed in the pressed state. Therefore, since no labor is required in a short time and anyone can easily form a double eyelid, the present forming tool of the present invention can be said to be a forming tool without any failure even for beginners. Moreover, since the adhesive liquid is not consumed unnecessarily more than necessary, it is very economical.

According to the invention of claim 2, the liquid supply member has a porous structure such as a porous body in which a parallel fiber bundle, felt, or plastic is fused by one or a combination of two or more specific fibers or resins. The adhesive component is a polymer having water solubility and lower alcohol solubility, or a polymer that dissolves in a water / lower alcohol mixture. Thus, in this forming tool, the liquid supply member has a porous structure necessary for the penetration of the adhesive liquid, and the adhesive liquid is spread over the entire area of the liquid supply member by capillary action or liquid flow due to an increase in the internal pressure of the container. At the same time, a very small amount of liquid is always supplied to the skin.

In addition to the porous structure, the liquid supply member absorbs the repulsive force of the skin and deforms into a curved state of less than a quarter of a circle when it contacts the skin. Provide structure. Accordingly, a material that does not cause rough skin even when there is friction due to repeated application of the adhesive liquid, while having an appropriate stiffness for forming the double eyelid.

In addition, the double eyelid can be easily repaired. Corresponding to individual differences in eyelid flesh, shape, etc., individual differences in the ability to form double eyelids and adhesive strength may also occur. In the unlikely event that the double eyelid formation part breaks and returns to its original state, the conventional applicator had to remove the hardened adhesive once and then perform a laborious work again. In the forming tool, since a low-viscosity and quick-drying adhesive liquid can be used, the adhesive can be repaired simply by tracing the folding line with the liquid supply member. Thus, it can be said that it is a great advantage because the fixing force can be increased by tracing the same part twice and three times.

Furthermore, the amount of the adhesive liquid used for forming the double eyelid per time by the applicator that stores the adhesive liquid of the conventional method in the brush brush tip in advance is about 0.01 g to 0.02 g (actual test measured value). However, the amount of the adhesive liquid used per one time formed by the porous structure liquid supply member of the present invention is about 0.001 g to 0.002 g (actual test measurement value), which is 1/10 of the conventional method. A double eyelid could be formed with the amount of liquid used. Thus, the double eyelid forming tool of the present invention is extremely economical and has excellent workability. Further, the present invention is different from the conventional method of bonding the adhesive liquid on the skin surface, and the adhesive liquid is uniformly applied to the entire concave wall surface of the skin folded by the pressing force of the liquid supply member. Therefore, a strong correction force is maintained with a very small amount of use. Therefore, there is no application amount or uneven coating, no sticking out of the adhesive liquid, and there can be no appearance problem even when applying makeup.

In addition, in the writing tip and ink of a normal writing instrument, when the viscosity becomes 100 mPa · s or more (preferably 50 mPa · s or less) for blending pigments, the fluidity is lowered and the line drawing is blurred or the pigment is clogged. Will cause problems. Moreover, the site | part used is only the point of a front-end | tip part, and what is called a point contact, and since it is used, it is necessary to concentrate a liquid on tip rotation. However, since the liquid supply member of the present invention is used as the contact surface for coating the entire surface of the protruding tip, a viscosity of 200 mPa · s (B-type viscometer ( 20 degrees) or less (preferably 100 mPa · s) can be used sufficiently.

According to the invention of claim 3, by preparing a plurality of types of liquid supply members having different tip shapes (conical shape, cylindrical shape, rectangular shape, etc.) in advance, the liquid supply member having an arbitrary shape is Can be integrated with the storage container. Accordingly, a double eyelid having a shape with different depth of folding wrinkles is formed according to the tip shape of the liquid supply member. That is, if the liquid supply member having a conical tip is used, the area into which the eyelid skin is folded is reduced, so that a folded wrinkle is formed (see d1 in FIG. 8B), and a shallow cut length is formed. It is possible to form an oriental double eyelid. On the other hand, if the liquid supply member is replaced with the liquid supply member whose tip is formed in a columnar shape or a rectangular parallelepiped shape, the area of the skin to be folded increases, and the liquid supply member is deeply folded (FIG. 9A). D2 of the back) By forming the folding wrinkles, it is possible to form the back double eyelid. By using liquid supply members having different tip shapes as described above, the shape of the double eyelid to be formed can be changed, so that it is possible to form the double eyelid according to one's preference.

It should be noted that the nature and properties of the eyelid skin vary greatly between individuals, and it can be said that there is less room for the skin to form a double eyelid as the age decreases. Moreover, since the tension and elasticity of the skin are strong, it is often difficult to make a deep double that folds deeply from the beginning to form wrinkles. Even in such a case, first use a conical liquid supply member to form a shallow folding wrinkle and replace it with a form in which the cylindrical part protrudes when the folding wrinkle becomes addictive. By doing so, it is possible to put the back double eyelids.

According to the invention which concerns on Claim 4, by forming the front-end | tip part and rear-end part of the said liquid supply member in a different shape, one liquid supply member from which front-end | tip shape differs is replaced, inserted and re-inserted, and used I can do it. In other words, the liquid supply member can be used properly depending on the shape of the double eyelid to be formed.

For example, if one of the liquid supply members has a conical shape with a pointed shape and the other has a cylindrical shape or a rectangular parallelepiped shape, a single liquid supply member has two folds with different wrinkle depths. A heavy eyelid can be formed. In particular, as described above, if there is no room in the skin for forming the double eyelid and it is difficult to fold deeply from the beginning to form wrinkles, the double double eyelid with a single liquid supply member Can be formed.

According to the invention according to claim 5, using the invention according to any one of claims 1 to 4, the skin of the eyelid is pushed in, the wrinkle in the folded state is held, and it is contacted so as to be wrapped. Applying a very small amount and a certain amount of adhesive liquid to the entire contact surface of the skin from the liquid supply member, and further folding by moving the forming tool. The skin immediately after passing through the skin is joined by the repulsive force of returning to its original state, and the skin surfaces are joined together by holding the folded wrinkles instantly and forming the double eyelid in a short time. Since no effort is required and anyone can easily form a double eyelid, it can be said that it is a formation method that will not fail even for beginners.

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

A first embodiment of the present invention will be described with reference to FIG. FIG. 1 includes a batting 3 impregnated with an adhesive liquid 4 for forming a double eyelid inside, and a liquid supply member 1 having a flexible structure such as a felt core and a conical shape 5 having a porous structure is fixed so as not to be removed. Or the double eyelid formation tool comprised with the liquid storage container 2 hold | maintained so that insertion / removal is possible is shown. The liquid supply member 1 has a distal end protruding from the liquid storage container 2 to the outside, and a base portion is in contact with the filling 3 stored in the liquid storage container 2 and is fixed to the container 2 or Removably held. The adhesive liquid 4 is supplied from the filling 3 to the entire liquid supply member 1 by a capillary action caused by the liquid supply member 1 having a porous structure. Further, the consumed adhesive liquid 4 is supplied to the liquid supply member 1 without interruption.

A second embodiment of the present invention will be described with reference to FIG. FIG. 2 shows a double eyelid forming tool that allows the liquid container 2 to be deformed by external pressure in the first embodiment. The liquid supply process of the adhesive liquid 4 to the liquid supply member 1 is the same as that in the first embodiment, but the material of the liquid storage container is molded from a plastic resin or the like. When an external pressure is applied from the outer wall 7, the internal pressure of the liquid container increases and the adhesive liquid 4 is forcibly supplied to the liquid supply member 1. When an adhesive liquid having a high viscosity is used, the liquid supply effect may be decreased due to a decrease in capillary action, but this example prevents the effect from decreasing. Therefore, in the contact between the liquid supply member 1 and the batting 3, along with the capillary action that occurs, the internal pressure of the container is increased by applying pressure from the outside of the container and the liquid is supplied from the batting 3 to the liquid supply member 1. Therefore, when the adhesive liquid is applied, the tip of the liquid supply member has a porous structure using the material described below so that a constant amount of the adhesive liquid is always supplied regardless of the strength of the pressing pressure.

Next, a third embodiment will be described with reference to FIG. FIG. 3 shows a double-layered relay core 8 having an outer diameter smaller than that of the liquid supply member 1 between the filling 3 impregnated with the adhesive liquid 4 and the liquid supply member 1 having a porous structure. An eyelid former is shown. One end of the relay core 8 is in contact with the liquid supply member 1, and the other end is in contact with the batting 3. The relay core 8 having a thin outer diameter. Capillary action larger than that of the liquid supply member 1 is generated, and the adhesive liquid 4 can be supplied from the filling 3 to the liquid supply member 1 more efficiently.

Next, a fourth embodiment will be described with reference to FIG. FIG. 4 shows a double eyelid forming tool that uses a liquid storage method in which the inside of the liquid storage container 2 has no filling 3 in the first embodiment. The base part of the liquid supply member 1 is impregnated with the adhesive liquid 4 stored inside the liquid storage container 2, and is supplied from the filling 3 to the entire liquid supply member 1 by the capillary action caused by the liquid supply member 1.

Next, a fifth embodiment will be described with reference to FIG. FIG. 6A shows a conical cylinder composite type forming tool having different shapes at both ends of a liquid supply member which can be inserted and removed in the first embodiment. In this embodiment, the tip is a conical shape 9a, and the base is a cylindrical shape 9b. Also, as shown in FIG. 6b, the tip and base can be used interchangeably in accordance with the shape of the double eyelid to be formed.

The points common to each embodiment will be described below.

The material used for the liquid supply member 1 needs to have a porous structure so as to generate a capillary action. Furthermore, it is necessary to have elasticity to absorb the repulsive force of the skin. In other words, in contact with the skin, a moderately stiff structure is desirable so that it deforms into a curved state of less than a quarter of a circle that absorbs the repulsive force of the skin, and it has elasticity and plastic softness. Use as a material. The reason is that the adhesive liquid is repeatedly applied to achieve elasticity that does not cause rough skin even when rubbed.

In view of the above points, the material of the liquid supply member 1 (the liquid supply member and the relay core in Example 3) needs to be a porous and flexible structure. From the experimental results described below, the liquid supply member 1 is A felt core, for example, a combination of an acrylic resin and a polyester resin is desirable.

Further, the liquid supply member 1 is a felt core, or a sponge (foamed body such as polyurethane resin) or a porous fiber bundle (for example, natural fiber, polyacetal resin, acrylic resin, polyester resin, polyamide) Resin, polyurethane-based resin, polyolefin-based resin, polyvinyl-based resin, polycarbonate-based resin, polyether-based resin, and polyphenylene-based resin. Conceivable. As a result, the tip of the liquid supply member 1 has a porous structure in which a constant amount of the adhesive liquid 4 is always supplied regardless of the strength of the pressing pressure, and has a necessary flexible structure.

Next, the protrusion length required for the liquid supply member 1 will be described.
The depth of the eyelid skin that is folded by the pressing force of a fine brush tip, etc., varies depending on the individual foldable skin, but the Japanese population is about 5 to 12 mm. And, in the case of the double eyelid forming tool of the present embodiment, the entire area of the protrusion of the liquid supply member is used to come into contact with the skin, and the inclination angle is preferably used with an inclination angle of 45 degrees or more with respect to the skin. Since the base of the forming tool is inclined in the direction of drawing a line and the tip of the liquid supply member is inclined in the opposite direction, the length of the liquid supply member pushed into the skin is 1.2 of the depth of the skin to be folded. It is desirable to set the length from double to 1.5 times, that is, from 6 mm to 18 mm.

Further, the protruding length of the liquid supply member 1 is such that the adhesive liquid 4 is applied in excess beyond the minimum skin area necessary for the adhesion of the double eyelids, and does not cause any pulling or discomfort due to an increase in the adhesion area. For this reason, it is desirable that it be within 30 mm at the longest.

Next, the shape necessary for the liquid supply member 1 will be described. FIG. 5 shows an example of the tip shape of the liquid supply member that can be used in each of the embodiments of FIGS. Considering the liquid supply part of a writing instrument that is generally used, the writing instrument draws a line drawing by making point contact with only its tip, so it is not necessarily assumed that the entire surface of the liquid supply part contacts an object such as paper. Not. However, in the case of the present invention, the object to be contacted is elastic skin, and there is a risk of damaging the skin by point contact at the tip. Therefore, the entire surface of the liquid supply member protruding from the container body is used as the contact surface, and the friction resistance between the skin and the liquid supply member at the time of contact is reduced, and the line is drawn by moving the skin and pushing on the skin. It is necessary to reduce the burden on the skin as much as possible and to make the movement as smooth as possible. Therefore, the shape of the liquid supply member is preferably a conical shape or a thin cylindrical shape that becomes thinner toward the tip as shown in FIG.

Here, the shape of the double eyelid formed by changing the shape of the liquid supply member can be changed. For example, if it is desired to form an oriental double eyelid with a shallow cut length (see d1 in FIG. 8 (b)), the tip portion to be brought into contact with the skin is pointed, for example, a cone shape, a deformed cone shape or It is preferable to use a triangular pyramid shape and have a cross-sectional diameter of 2 mm or less at the tip. Further, if it is desired to form a deep western double eyelid (see d2 in FIG. 9 (a)), the tip portion is formed in a columnar shape, a deformed columnar shape, or so as to deepen wrinkles in the skin. It is preferable to have a rectangular shape and a cross-sectional diameter or a minimum cross-sectional width of 3.5 mm or less.

FIGS. 7A, 7B, and 7C are enlarged views of the liquid supply member 1 held in the liquid storage container 2. The liquid supply member 1 soaks and swells with the adhesive liquid and has a cross-sectional area. By enlarging, the liquid container 2 is pressed and fixed to the inner wall of the tip opening of the liquid container 2. Here, in order to prevent the liquid supply member 1 from being inserted too far from the tip of the liquid storage container 2, a line is inserted at a position where insertion should be stopped as shown in FIG. As shown in b), when the liquid supply member 1 is fixed, the portion that protrudes to the outside of the liquid storage container 2 and the portion that is inserted into the inside are color-coded, and the user clearly identifies where the insertion should be stopped It is desirable to be able to grasp. Further, as shown in (c), it is more desirable that the convex portion 1a is provided on the outer periphery of the liquid supply member 1 and the concave portion is provided at the tip of the liquid storage container so that both portions are fitted and fixed.
In order to prevent drying after using this forming tool, for example, it is desirable to always prepare and cover the drying preventing cap 6 of the liquid supply member 1 as shown in FIG.

Next, the inside of the liquid storage container 2 will be described. If the inside of the liquid storage container 2 is a system that can supply liquid to the liquid supply member 1 by capillary action or the internal pressure of the container, for example, a system having a conventional batting, a system for storing liquid without batting, or a physical A form with an extrusion function can be adopted. Here, in Examples 1 to 3 and 5, the batting 3 is adopted, but the adhesive liquid 4 is supplied without interruption to the liquid supply member 1 even if the present forming tool is turned upside down and turned to any angle such as sideways. In consideration, the method with the filling (see FIGS. 1 to 3 and 3 in FIG. 5) is more desirable than the method of storing the liquid without filling in Example 4 (see FIG. 4).

Next, the adhesive liquid 4 will be described. The component of the adhesive liquid needs to promote the liquid supply, improve the liquid permeation effect, shorten the initial adhesion time, and prevent rough skin. Therefore, in view of the above points and the experimental results for the test subjects described later, the best adhesive liquid composition is the ethanol-soluble acrylic acid / acrylic acid amide / ethyl acrylate copolymer described in [Adhesive liquid 1] described later. 10.0 parts by weight of a polymer (BASF) was dissolved in 87.0 parts by weight of absolute ethanol (Japanese alcohol) and 3.0 parts by weight of PEG-8 (BASF), and the viscosity coefficient was 50 mPa · s / 20 ° C. It is most desirable from the experimental results described later. On the other hand, it is also possible to use an adhesive that satisfies the following conditions.

The composition of the adhesive liquid that can be used is as follows: first, water or lower alcohol, which is an adhesive component, water / lower alcohol-soluble polymer is a predetermined part by mass; second, water, or lower alcohol, and a water / lower alcohol mixture is a predetermined part by mass. Thirdly, the other components are constituted by a predetermined part by mass as required. Viscosity for the liquid supply member with a porous structure to flow from the liquid storage container with capillary action or pressure inside the container, or a very small amount that enables the formation of a double eyelid instantaneously while pushing the skin with the liquid supply member In order to secure adhesive strength or to maintain the adhesive strength depending on the elapsed time for fixing the wrinkles that have been folded, water or lower alcohol as a solvent, water / lower alcohol mixture, The minimum solid content concentration of the alcohol-soluble polymer needs to be 5 parts by mass or more and 50 parts by mass or less which makes it difficult to distribute the liquid to the liquid supply member. In the case of a water-soluble polymer, it is desirable to combine a lower alcohol in order to promote liquid supply, increase the liquid permeation action, or increase the initial adhesion time.

Adhesive component is water or lower alcohol, water / lower alcohol soluble polymer, vinyl pyrrolidone / vinyl acetate copolymer (BASF), vinyl pyrrolidone / acrylate copolymer (BASF), vinyl acetate / croton copolymer (BASF) Polyvinylpyrrolidone resin (BASF), acrylic acid ester / methacrylic acid ester copolymer (compatible chemical), hydroxyethyl acrylate / methoxyethyl acrylate copolymer liquid (compatible chemical), hydroxyethyl acrylate / acrylic Butyl acrylate / methoxyethyl acrylate copolymer liquid (reciprocal chemistry), alkanolamine acrylate liquid (reciprocal chemistry), vinyl acetate / crotonic acid copolymer resin (NSC), methyl vinyl ether maleic acid half ester (ISP), Vinylpyrrolidone / vinyl acetate / vinyl propionate copolymer (BASF), t-butyl acrylate Acrylate / ethyl acrylate / methacrylic acid copolymer (BASF), acrylates / acrylamide copolymer (BASF), (acrylates / lauryl acrylate / stearyl acrylate / methacrylic acid ethylamine oxide) copolymer, acrylic acid / acrylic Acid amide / ethyl acrylate copolymer (BASF) vinyl acetate / butyl maleate / isobornyl acrylate copolymer (ISP), dialkylaminoethyl methacrylate copolymer (ISP), alkyl acrylate Any component that is used in an adhesive such as a polymer (BASF) may be used. Alternatively, naturally derived components such as cellulose derivatives, rosin, shellac, sericin, keratin, casein, pullulan, or derivatives can be used. These 1 type, or 2 or more types can be mixed and used. It is desirable to use a lower alcohol preferentially because it is a mechanism for achieving a capillary wrinkle action or a liquid flow with a container internal pressure. The lower alcohol as the adhesive component may be used in the form of a mixture of absolute ethanol, denatured ethanol, or isopropyl alcohol.

In addition, as other components, it promotes capillary wrinkle action or liquid permeability by reducing surface tension, softens adhesive components, prevents dryness of felt, sponge liquid supply members, etc., liquid supply member on skin Considering the frictional resistance reducing action, skin protecting component, moisturizing component, etc., surfactants, polyhydric alcohols, glycols, silicones, plant extracts, fragrances, preservatives, antibacterial agents, protective agents, Pigments, colorants, and the like can be mixed in a mass that does not inhibit the solid content concentration required as an adhesive component.

Next, a usage example of the present invention will be described. 8 (a) to 8 (c) and FIGS. 9 (a) and 9 (b) show a series of usage methods of the present forming tool and states before and after use. The conical liquid supply member 1 in this forming tool is pressed from the lower side toward the skin 10 shown in FIG. 5A and pushed inward, and the folded skin 10 wraps the liquid supply member 1 having a porous structure. (I.e., substantially the entire circumference of the liquid supply member). The adhesive liquid is uniformly applied to the portion 11 in contact with the liquid supply member. If the base of the forming tool is tilted 45 degrees or more so as to face the direction of travel, it is moved so as to draw a line along the outline of the eye, and the surfaces to which the adhesive is applied are joined to the skin surface. Folds are instantly formed and the double eyelid is completed.

Here, the liquid supply test to the felt core liquid supply member and the fiber core liquid supply member performed in the present invention will be described. Adhesive solution 1 using applicator UC-38 (liquid storage container) manufactured by Mitsubishi Pencil Co., Ltd. with a flexible felt core (material acrylic, polyester cone type, core length 12 mm) attached to the liquid supply member 3 and 3 were used as Experimental Examples 1 and 3, and a liquid supply test by capillary action and a skin application test on the eyelids were performed. On the other hand, a flexible fiber bundle (material acrylic, polyester cylindrical type, width 3 mm, length 15 mm) is used as the liquid supply member, and the liquid is provided at the center of the shaft so that the adhesive liquid is pushed out by the piston. Using an applicator-UC-22 (liquid storage container) manufactured by Mitsubishi Pencil Co., Ltd., to which a fine tunnel-shaped path having a diameter of 0.5 mm that can be distributed was attached, the adhesive liquids 2 and 4 were filled. These were designated as Experimental Examples 2 and 4, and liquid supply tests were performed with the internal pressure of the container applied. In addition, the following four types of adhesive liquids were used.

Adhesive liquid 1 comprises 10.0 parts by weight of ethanol-soluble acrylic acid / acrylic acid amide / ethyl acrylate copolymer (BASF), 87.0 parts by weight of absolute ethanol (Japan alcohol), PEG-8 (BASF) It is dissolved in 3.0 parts by weight and has a viscosity coefficient of 50 mPa · s / 20 ° C.

Adhesive liquid 2 is ethanol-soluble acrylic acid / acrylic acid amide / ethyl acrylate copolymer (BASF) 20.0 parts by weight absolute ethanol (Japan alcohol), PEG-8 (BASF) 5.0 It is dissolved in parts by weight and has a viscosity coefficient of 120 mPa · s / 20 ° C.

Adhesive liquid 3 is ethanol-soluble (alkyl acrylate / diacetone acrylamide) copolymer AMP (Kyoto Chemical Co., Ltd.) 20.0 parts by weight (50% ethanol), absolute ethanol (Japan alcohol) 70.0 parts by weight, purified water It is dissolved in 5.0 parts by weight and 5.0 parts by weight of glycerin (Wako Pure Chemical Industries, Ltd.) to give a viscosity coefficient of 78 mPa · s / 20 ° C.

4. Adhesive liquid 4 is ethanol-soluble (acrylic alkyl / diacetone acrylamide) copolymer AMP (Kyoto Chemical Co., Ltd.) 35.0 parts by weight (50% ethanol), anhydrous ethanol (Japan alcohol) 55.0 parts by weight, purified water 5. It was dissolved in 0 part by weight and 5 parts by weight of glycerin (Wako Pure Chemical Industries, Ltd.) to give a viscosity coefficient of 150 mPa · s / 25 ° C.

As a result of the liquid supply test, the liquid supply in Experimental Examples 1 and 3 was extremely good.
In Experimental Examples 2 and 4, the solid content and concentration were high, but were satisfactory if the liquid was supplied by the internal pressure. The preferred order is Experimental Example 1- Experimental Example 2- Experimental Example 3- Experimental Example 4.

Here, the skin contact resistance and the coating sensory test in the adhesive liquid were performed. The skin contact resistance of the eyelid epithelium and the applied sensory test were conducted using the adhesive of the present invention using five subjects. The test was conducted by actually filling the forming tools with adhesive liquids 1 to 4 and actually using them, and listening to opinions on the following contents. There are three points: (1) “Ease of applying adhesive liquid to the skin”, (2) “Uncomfortable feeling from the brush tip”, and (3) “Whether the skin has redness”. However, the following results appeared.

First, when asking about the ease of application of (1), in Experimental Examples 1 to 3, all five responded that they were easy to apply. On the other hand, when Experimental Example 4 having a relatively high viscosity was tested, 4 out of 5 responded that it was easy to apply, and the remaining 1 answered normal. On the other hand, regarding the discomfort in (2) and the redness on the skin in (3), all five responded that there was no discomfort or redness.

Therefore, when the double eyelid former and the forming method of the present invention are implemented, it is considered that there was no skin trouble due to the uncomfortable feeling and redness of the adhesive liquid filled in the soft felt core. On the other hand, in specific example 2 and specific example 4, since the viscosity is 100 mP · s / 20 ° C. or higher, it is not suitable for liquid supply by capillary action. . The efficiency of penetration of the liquid supply was in the order of specific example 1-specific example 2-specific example 3-specific example 4 of the adhesive liquid, but the difference was not great. It can be inferred that the structural viscosity of the polymers of the adhesives 3 and 4 used in the specific examples 3 and 4 has an influence. As described above, depending on the type, concentration, viscosity, and the like of the polymer, a method of supplying it by liquid circulation using internal pressure can be selected.

Next, by 10 test subjects who have used or are currently using a conventional brush brush type forming tool for forming a double eyelid, the present forming tool containing the double eyelid adhesive liquid of the present invention is used again. A double eyelid formation test was conducted. As in the previous test, the test samples were actually used by putting the adhesive liquids 1 to 4 into the former and actually using them, and listening to opinions on the following contents. The contents are the following four points: (1) Are you satisfied with the ability to form a double eyelid in this forming tool, (2) Do you simply feel ease of use, or (3) Completed double eyelid When asked whether it feels uncomfortable or (4) it feels superior compared to the conventional product (brush brush type forming tool), the following results appeared (see Table 1 below).

From Table 1, it is considered that the double eyelid adhesive liquid and the forming method of the present invention have obtained excellent evaluation from the test results obtained by the conventional users who have used the double eyelid. In particular, Experimental Example 1, which has a relatively low viscosity, and Experimental Example 2, which has a high viscosity but uses an internal pressure, are extremely highly evaluated. However, in the case of having comparatively high viscosity in Experimental Example 3 and Experimental Example 4, the same liquid circulation method is used, but the viscosity is low, and the adhesive strength is faster in terms of quick drying than Experimental Example 1 and Experimental Example 2. The evaluation declined because it was weak. Although Experimental Example 2 and Experimental Example 4 have high viscosities and solids concentrations, the test was conducted by a liquid circulation method using the internal pressure of the container, but the evaluation of Experimental Example 2 which is faster drying and excellent in adhesive strength is high. Based on the above experimental results, it is considered that the present double eyelid forming tool and the forming method are highly evaluated.

In the present invention, applying the adhesive liquid as thinly and uniformly as possible is the point of forming a beautiful double eyelid that is personally preferred, and can be said to be important for ease of use and reduction of discomfort. Accordingly, since the amount of liquid to be applied is instantly dry and extremely small, it can be said that it is a double eyelid forming tool and a forming method with less uncomfortable feeling than before even during double eyelid correction. Since the liquid supply member of the present invention is a method that uses the entire surface of the portion projected from the stick shaft of the applicator, there are advantages such as reduced skin contact resistance and good consumption efficiency of the adhesive liquid. .
