Further, the inner peripheral portion of the liquid guiding body 20 is formed to have substantially the same diameter. As shown in Fig. 2, the rear end portion of the liquid guiding body 20 abuts against the flange 10a of the application portion 10 for preventing the application portion 10 from falling out of the liquid guiding body 20.

[Relay Core 14] As shown in Fig. 8, the relay core 14 is formed in a concave portion 14a on the peripheral surface of the distal end portion, and is inserted into the collector 18 as shown in Figs. 1 and 2, and is inside the collector 18. The circumferential projection (the convex portion 18f: see Fig. 4) has a structure in which it is fitted into the concave portion 14a and is stopped. The relay core 14 is made of a fiber bundle such as a resin material or a molded core, and is capable of guiding the liquid by exerting capillary force. The material of the relay core 14 is preferably formed of a material that does not substantially contain formaldehyde such as an olefin-based elastomer. In the case of a material containing formaldehyde, it is not suitable as a makeup tool for the release of formalin from the relay core 14 into the cosmetic liquid. Further, as the material of the relay core 14, a material such as an acetal type such as polyacetal or a phenol resin, a urea resin used for an adhesive, or a melamine resin is preferable.

[Cosmetic material] The applicator of the first embodiment is a liquid cosmetic applicator that is suitable for use as the applicator 10, such as a pen or a refill, and the liquid cosmetic contained in the liquid storage portion 16a contains at least carbon black. 0.5 to 5 mass% of a dispersing agent composed of water and a film-forming resin, 2 to 15% by mass of a film forming agent (in terms of solid content), and 0.5% by weight or less of a surfactant, and measured by an ELD type viscometer The viscosity at a temperature of 25 ° C and a shear rate of 3.83 S ^-1 can be set in the range of 2 to 8 mPa·s.

The carbon black for the cosmetic material is used as a color material, and the color material of the black liquid cosmetic is not particularly limited as long as it is a commonly used carbon black, and various carbon blacks can be used.

The content of the carbon black is preferably from 1 to 20% by mass, more preferably from 5 to 15% by mass, based on the total amount of the liquid cosmetic. When the content of the carbon black is less than 1% by mass, the color is light and not sufficient as a cosmetic. On the other hand, if it exceeds 20% by mass, the viscosity is too high, and liquid makeup such as a collector type or a medium cotton type cannot be used. The spreader spit out smoothly and is therefore not good.

The dispersing agent used for the above-mentioned cosmetic material is composed of a film-forming resin, and the coloring material, that is, the dispersibility of carbon black is improved and also functions as a resin of a film formed.

Further, the dispersing agent which can be used for the above-mentioned cosmetic material is not particularly limited as long as it has the above functions, and examples thereof include those selected from the group consisting of acrylic acid, methacrylic acid or the alkyl ester or derivative thereof, and vinyl acetate. A copolymer composed of one or more of vinylpyrrolidone or a betaine-based alkyl acid amphoteric resin is preferably selected from the group consisting of acrylic acid and A from the viewpoint of further dispersibility of carbon black. a copolymer of one of the alkyl acrylates or the alkyl esters or derivatives and a copolymer of vinyl acetate, a copolymer of vinylpyrrolidone and vinyl acetate, acrylic acid, methacrylic acid or an alkyl ester thereof, and octyl A copolymer of a acrylamide is preferably desired, and further preferably one or more of acrylic acid, methacrylic acid or an alkyl ester, and octyl acrylamide, from the viewpoint of dispersibility and film formation energy. Copolymer.

The content of the dispersant is preferably 0.5 to 5% by mass, more preferably 2 to 4% by mass based on the total amount of the liquid cosmetic.

When the content of the dispersant is less than 0.5% by mass, the dispersion stability of the color material, that is, carbon black is insufficient. On the other hand, when the content exceeds 5% by mass, the viscosity is too high and the dispersion stability is not improved, so that it is uneconomical. .

The film forming agent used for the above-mentioned cosmetic material may, for example, be one or more selected from the group consisting of acrylic acid, methacrylic acid or such alkyl esters or derivatives, styrene, and vinyl acetate. An emulsion resin of a copolymer composed of a body.

In the cosmetic, the dispersant is also composed of a film-forming resin, and is different from the dispersant in that the soluble resin and the emulsion resin are different, and the emulsion resin emulsifies the monomer in water as a polymerization solvent. A water suspension obtained by polymerization. When the carbon black in the aforementioned cosmetic material is dispersed, the soluble resin can obtain a carbon black dispersion liquid which is more stable than the emulsion resin. This point distinguishes users.

The content of the film forming agent (emulsion resin) is preferably 2 to 15 mass, more preferably 2 to 10% by mass, based on the total amount of the liquid cosmetic in terms of the solid content (resin component).

When the content of the film forming agent (emulsion resin) is less than 2% by mass in terms of the solid content (resin component), the water resistance is poor, and when the solid content (resin component) is more than 15% by mass, the liquid is contained. When the application portion (pen or refill, etc.) of the cosmetic applicator is dried, there is a problem that it cannot be applied, and thus it is not preferable.

Further, in order to stabilize the film forming agent (emulsion resin), a surfactant is also used. However, the surfactant to be blended has little influence on the fixing property of the present invention, and therefore the content is not considered.

The surfactant used for the liquid cosmetic is a function of dispersion assistance in the dispersion of carbon black, and examples thereof include a nonionic surfactant, an anionic surfactant, and a cationic surfactant, and In addition to lecithin, propylene glycol fatty acid ester, glycerol fatty acid ester, polyglycerol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether polyoxyethylene polyoxypropylene One or a mixture of two or more kinds of alkyl ether, polyoxyethylene alkyl ether phosphate, phosphate, polyethylene glycol fatty acid ester, alkyl sulfate, sulfonate, polyoxyethylene alkyl ether sulfate .

The content of the surfactant is preferably 0.5% by mass or less, more preferably 0 to 0.3% by mass, based on the total amount of the liquid cosmetic.

When the content of the surfactant is more than 0.5% by weight, the water resistance is inferior and a sufficient fixing force cannot be obtained, which is not preferable.

The liquid cosmetic contains water (including purified water, distilled water, ion-exchanged water, pure water, ultrapure water, etc.) as a solvent. The content of the water is the remainder of the above-mentioned respective components and any of the components described later.

In addition to the above-described respective essential components, the liquid cosmetic may contain any component or the like used in a usual liquid cosmetic. Specifically, the preservative, the oxidation preventing agent, the neutralizing agent, the ultraviolet absorber, the chelating agent, the moisturizing agent, the cosmetic component, the fragrance, the viscosity adjusting agent, and the like may be contained in an appropriate amount as long as the effect of the cosmetic is not impaired.

The liquid cosmetic is preferably measured by an ELD type viscometer at a temperature of 25 ° C and a shear rate of 3.83 S ^{-1 in} a range of 2 to 8 mPa·s, particularly preferably 3 mPa·s to 6 mPa·s.

When the viscosity is less than 2 mPa·s, the liquid flows into wrinkles or the like and causes bleeding. On the other hand, when the viscosity exceeds 8 mPa·s, the viscosity is high. Therefore, the liquid using the pen tip or the refill as the application means of the present invention is used. The liquid cosmetic material contained in the cosmetic smear does not discharge smoothly, which is not preferable. In addition, the viscosity measurement conditions (including the examples and the like described later) are specifically measured by the Tokimeku Corporation, ELD-type viscometer standard Cone-Rotor 1 rpm at a temperature of 25 ° C and a shear rate of 3.83 (S ^-1 ).

According to the applicator of the first embodiment, the plurality of application liquid guiding grooves 18d are formed in the collector 18, and the flowability of the application liquid is improved, so that the liquid can be reliably supplied from the relay core 14 to the liquid guide. The body 20 and the smear portion 10 have such an excellent effect.

In particular, since the flange portion 10a is formed in the application portion 10, but the distal end portion of the relay core 14 is protruded, the size does not depend on the outer diameter of the relay core 14, so that the application portion 10 can be easily reduced in size.

Fig. 9 to Fig. 12 are explanatory views of the applicator of the second embodiment.

The difference from the applicator of the first embodiment is that the plurality of grooves of the guiding liquid are not the collector 18 but are formed in the relay core 14, and the weight components are accommodated in the rear portion of the shaft body 16.

Specifically, as shown in Fig. 10 and Fig. 11, the applicator guiding groove of the applicator of the first embodiment is not formed in the collector 18, but a flat surface is formed from the front end portion to the inside. Further, as shown in Fig. 12, a plurality of application liquid guiding grooves 14b are formed on the outer circumference of the relay core 14 in the longitudinal direction. The application liquid guiding groove 14b preferably has a width corresponding to the viscosity of the application liquid and a capillary force to guide the application system to the application portion. However, in the embodiment, it is preferably 0.1 to 0.5 mm. Further, as the material of the relay core 14, it is preferable to form it by an elastomer material containing no formaldehyde. Further, a segment portion 18el is formed such that the distal end portion 14c of the relay core 14 is expanded in diameter and fitted to the front side of the collector. Further, the distal end portion 14c has a bowl shape, and is a configuration in which the rear end of the application portion 10 and the flange 10a are fitted together with a concave portion at the distal end.

Further, in the applicator of the second embodiment, the filling body 16cl is housed as a weight component, and the filling body 16cl is housed in a space closed by the tail plug 16c disposed at a rear portion of the partition wall 16b of the shaft body 16. Inside. By accommodating and fixing the body 16cl of the weight component to the rear of the barrel 16 by the tail pin 16c, the center of gravity of the applicator is changed from the center to the rear with respect to the axial direction, so that the feeling of use of the eyeliner or the like can be improved ( Refer to Figure 9).

According to the applicator of the second embodiment, the plurality of application liquid guiding grooves 14b are formed in the relay core 14, and the flow of the application liquid is improved, whereby the liquid can be reliably supplied from the relay core 14 to the liquid guide. The body 20 and the smear portion 10 have such an excellent effect.

Further, since the weighted body 16cl is housed in the rear portion of the shaft body 16, the weight is averaged and it is easy to apply.

Further, in the second embodiment, as a suitable liquid cosmetic, a glass obtained by polymerizing monomers selected from the group consisting of an acrylic monomer, a methacrylic monomer, an acrylate monomer, and a methacrylate monomer is transferred. An aqueous emulsion of an acrylic polymer having a transition point of 20 ° C or less, fermented cellulose, a color material containing at least a flat pigment, and a liquid cosmetic containing water. Further, it is preferable that the liquid cosmetic having the following characteristics is that the aqueous emulsion of the acrylic polymer is 2 to 20% by mass, the fermented cellulose is 0.05 to 0.6% by mass, and the at least a flat plate is used. The color material of the pigment, the iron oxide particles, and the chelating agent is 1 to 30% by mass, and the viscosity at a temperature of 25 ° C and a shear rate of 76.6 S ^-1 measured by an EMD type viscosity meter is 30 to 200 mPa·s. According to the second embodiment, it is possible to provide a coloring unevenness which is not interrupted on the skin during application, and which is not bright, and which can draw a bright line with a low viscosity which is less dripping (sprinkling). .

When the liquid cosmetic is described in detail, the aqueous emulsion of the acrylic polymer may be one or two selected from the group consisting of an acrylic monomer, a methacrylic monomer, an acrylate monomer, and a methacrylate monomer. The aqueous emulsion having a glass transition point of 20 ° C or less obtained by polymerizing the above monomers is not particularly limited, and various aqueous emulsions can be used. The aqueous emulsion of the acrylic polymer to be used is a film forming agent user, and it is preferable to use a glass transition point (Tg) of -20 ° C or more from the viewpoint of film forming property and elasticity of the formed film. Aqueous emulsions below 20 ° C are desirable. Further, when the glass transition point exceeds 20 ° C, the elasticity of the dried cosmetic material and the film formation property are lowered, and the makeup durability is lowered, which is not preferable. In the present invention, the glass transition point (Tg) is measured as follows. First, the resin is varnished, and a varnish-like resin is formed into a film, followed by drying by drying the solvent. The thinned acrylic resin was heated from -20 ° C to +150 ° C at a temperature increase rate of 10 ° C/min using a differential scanning calorimeter (DSC) manufactured by Rigaku Co., Ltd. to measure the differential scanning heat, and the obtained endothermic curve was obtained.
