BACKGROUND OF THE INVENTION
The present invention has a ball holder that discharges a part of a ball as an application member from a tip hole and rotatably holds the ball, and the application liquid that passes through the inside of the ball holder is removed between the ball and the ball holder. The eyeliner, eyebrow, nail color, which fills in a so-called ball-point pen type applicator, which is an applicator having an application destination that is discharged from the tip hole through, and draws a beautiful line when the discharge is applied smoothly. The present invention relates to a liquid cosmetic filled in a lip color for contour formation.
[0002]
[Prior art]
Conventionally, most eyeliners and nail colors are used in which cosmetics mainly composed of pigment, water, and emulsion are filled in a bottle-like container and attached to a brush. In addition, a pencil type that is formed into a rod shape with pigment and wax as main components and formed into a pencil core shape is used as an eyeliner and eyebrow, and in the same way, a rod type with pigment, wax, and solvent as main components is used. The one is commonly used as a lip color. Furthermore, a low-viscosity liquid cosmetic material composed of a pigment, water, and a solvent filled in a felt pen type or ballpoint pen type applicator is known as an eyeliner or nail color.
[0003]
[Problems to be solved by the invention]
However, these eyeliner, eyebrow, nail color, and lip color have various problems. For example, (1) it is difficult to draw a certain thin line with the brush type, (2) if the lid is opened, the solvent evaporates and the ink is easily cured, and (3) it is inconvenient to carry. The pencil type and the rod type are (1) the outline is not a clear line, and (2) the powder or semi-solid is attached to the skin, so the makeup is easily broken. Furthermore, in pen-shaped cosmetics, the tip of the pen may become clogged with pigment, and in the case of ball-point pen types, the viscosity of the cosmetic remains high during application, so the ball will rotate unless pressed against the skin with a considerable force during application. There have been problems such as inability to draw lines and the occurrence of bleeding due to easy movement of the cosmetic after application.
[0004]
An object of the present invention is to provide a liquid cosmetic that fills a ball-point pen type applicator and is easy to draw a certain thin line with a light force and does not blur the drawn line.
[0005]
That is, the present invention has a ball holder that discharges a part of a ball as an application member from a tip hole and rotatably holds it, and urges the ball forward with a force of 5 g to 7 g inside the ball holder. A coil spring is disposed to show a non-Newtonian viscosity passing through the inside of the ball holder, and a liquid cosmetic having a non-Newtonian viscosity index in the range of 0.1 to 0.9 is passed through the gap between the ball and the ball holder. A gist is an applicator having an application destination discharged from the tip hole .
[0006]
Hereinafter, the present invention will be described in detail.
The liquid cosmetic in the present invention has non-Newtonian viscosity. The viscosity η (Pa · s) of the liquid having non-Newtonian viscosity is expressed by the following equation: η = μD ^n-1 (μ: non-Newtonian viscosity coefficient, D: shear rate (1 / s), n: non-Newtonian viscosity index) Is generally represented by
In this case, the smaller the value of the non-Newtonian viscosity index n, the smaller the viscosity increases with respect to the shear rate, and the smaller the force required when the ball rotates.
In order to impart this non-Newtonian viscosity, it is effective to add a polymer that imparts non-Newtonian viscosity. Examples of polymers that impart non-Newtonian viscosity include xanthan gum, gar gum and derivatives thereof, galactomannan, alginic acid and salts thereof, succinoglucan, starch, carrageenan, gellan gum, curdlan, pullulan, lambzan gum, welan gum, CMC (Carboxymethylcellulose) alkali metal salts such as sodium salt, cellulose derivatives such as HPC (hydroxypropylcellulose) and HEC (hydroxyethylcellulose), hyaluronic acid, chondroitin sulfate, polyacrylic acid and salts thereof, cross-linked polyacrylic acid and Examples thereof include salts, copolymers of cross-linked acrylic acid and acrylic acid esters and salts thereof, and poly N-vinylacylamide.
The amount of these used is preferably 0.01 to 10% by weight based on the total amount of the cosmetic. If it is less than 0.01% by weight, the decrease in viscosity during application is small, and light application may not be possible. If it exceeds 10% by weight, the viscosity of the cosmetic may become too high, and ejection during drawing may not be performed smoothly.
[0007]
Water is used as the main solvent.
As the colorant, various colorants such as dyes and pigments can be used for cosmetics. For example, Red No. 2, Red No. 3, Red No. 102, Red No. 104, Red No. 105, Red No. 106, Yellow No. 4, Yellow No. 5, Green No. 3, Blue No. 1, Blue No. 2, Red 201, Red 2020, Red 203, Red 204, Red 205, Red 206, Red 207, Red 208, Red 213, Red 214, Red 215, Red 218, Red 220 No., Red 221, Red 223, Red 225, Red 226, Red 230, Red 231, Red 232, Orange 201, Orange 203, Orange 204, Orange 205, Orange 206, Orange No. 207, Yellow No. 201, Yellow No. 202, Yellow No. 203, Yellow No. 205, Green No. 201, Green No. 202, Green No. 204, Green No. 205, Blue No. 201, Blue No. 202, Blue No. 203, Color No. 204, Brown No. 201, Purple No. 201, Carbon black, bitumen, ultramarine blue, yellow iron oxide, red iron oxide, black iron oxide, chromium hydroxide, chromium oxide, titanium oxide, low-order titanium oxide, mica titanium, calamine , Squid, aluminum powder, mica, fish scales, bismuth chloride and the like. Furthermore, various resin spheres and hollow resin spheres can be used. These can be used alone or in combination, and the amount used is preferably 0.1 to 50% by weight in the total ink. If the concentration is less than 0.1% by weight, the concentration is thin, and if it exceeds 50% by weight, there is almost no improvement in the concentration of the coating mark, and the meaning of adding more is not recognized.
[0008]
A water-soluble organic solvent is used to prevent the tip of the applicator from drying out so that a beautiful line can always be drawn from the writing. For example, ethylene glycol, propylene glycol, 1,3-butylene glycol , Glycerin, polyethylene glycol and the like can be used. The amount of these water-soluble organic solvents used is preferably 2 to 30% by weight based on the total amount of the cosmetic. If it is less than 2% by weight, there is no effect of preventing the nib from drying, and if it exceeds 30% by weight, the applied wire is difficult to dry.
In addition to the above essential components, surfactants, antiseptic / antifungal agents, pH adjusters for adjusting the application properties to the skin, resins for fixing the skin and water resistance of the applied cosmetics, coloring In the case of using a pigment as a dispersant, for example, a styrene-acrylic acid copolymer, a styrene-maleic acid copolymer, an acrylic acid-acrylic acid ester copolymer salt, a shellac, a resin such as humic acid, Surfactants such as POE alkyl ether, POE alkyl phenyl ether, POE alkyl ether phosphoric acid and salts thereof, POE / POP alkyl ether, and POE sorbitan fatty acid esters can be used as necessary.
[0009]
The liquid cosmetic of the present invention can be produced by a generally used method. For example, in the case of a pigment, a dispersant is dissolved or dispersed in water, and after adding the pigment to this, it is dispersed by a conventionally known medium dispersing machine such as a three-roll mill or a bead mill. It can be created by adding other ingredients and stirring. At this time, coarse particles that cannot be dispersed may be removed by filtration or centrifugation to make the particles uniform.
When a dye is used as a colorant, it can be obtained by mixing and stirring all components.
Components that can be added other than the essential components may be added either before or after dispersion.
[0010]
As the ball-point pen type applicator used in the present case, various kinds of tips such as those made of metal such as stainless steel or white or those formed by molding a resin such as acetal resin, PET, PBT, etc. can be used. As the balls, various kinds of balls such as cemented carbide balls mainly composed of tungsten carbide and balls mainly composed of various ceramics such as zirconia and silicon carbide can be used. In addition, in order to guide liquid cosmetics to the vicinity of the ball, a fiber bundling body, a synthetic resin, or a metal rod may be used as a liquid lead-out member. For excessive control, a ball member serving as a valve may be arranged inside the ball holder or in a liquid storage member connected to the ball holder or a connecting member to the liquid storage member, or the ball at the tip may be formed by a coil spring or the like. May be pressed against the edge of the hole of the ball holder. In addition, when a coil spring or the like is disposed, it is preferable to suppress the elasticity of the coil spring from being excessively irritating to the skin to which the coating is applied, and to prevent the liquid from being obstructed. It is preferable to secure a liquid lead-out path by an appropriate method such as a groove in the attachment portion of the spring.
The ball diameter is preferably 0.4 mm to 2.0 mm. If it is less than 0.4 mm, there is a possibility that a clear application trace cannot be obtained because the amount of cosmetic discharge is reduced and the application trace becomes very thin. On the other hand, if the thickness exceeds 2.0 mm, the width of the coating mark may be excessively widened, or the amount of discharge may be excessively increased to cause bleeding, which may cause the coating mark to become unclear.
[0011]
[Action]
The reason why the liquid cosmetic of the present invention can be applied with a light force during line application and the line after application does not bleed is presumed as follows.
Since the applicator of the present case is a ball-point pen type, the cosmetic is discharged through the gap between the ball and the chip that holds the ball as the ball held at the tip of the pen rotates. Since this gap is very narrow and the ball rotates rapidly, a considerable shearing force is applied to the cosmetic. Since the cosmetic of the present invention has a non-Newtonian viscosity, when a shearing force is applied, the viscosity of the thickener used decreases due to the collapse of the structural viscosity in the cosmetic. For this reason, the viscosity of the cosmetic is greatly reduced, and the ball can be rotated even with a light force. As a result, it can be applied to the skin with a light force.
In addition, as soon as the shearing force disappears, the structure between thickeners forms a viscosity and returns to the original viscosity, so that the cosmetic applied to the skin does not move over time, so no bleeding occurs it is conceivable that.
[0012]

Examples will be described in more detail below. Note that “parts” simply means “parts by weight”.
The viscosity is measured using an ELD viscometer manufactured by Toki Sangyo, and the rotor is measured using a 3 ° × R24 cone rotor when the viscosity is 1000 mPa · s or less, and using an ST rotor when exceeding 1000 mPa · s. did.

[0020]
Table 1 shows the results of the application test and the bleeding test performed on the liquid cosmetics obtained in Examples 1 to 4 and Comparative Examples 1 to 4.
The test applicator sample was prepared by connecting the application destination holding the ball of the liquid cosmetic obtained in the examples and comparative examples to the cosmetic tank, and arranging a backflow prevention means at the interface portion of the cosmetic. . Specifically, it is shown in FIGS.
[0021]
That is, as shown in FIG. 1, which is an enlarged cross-sectional view of a partially omitted applicator, an application destination holder 2 that is an injection-molded product of polypropylene resin is connected to the front end of a pipe 1 by extrusion molding made of polypropylene resin. The application destination 3 is connected to the tip of the application destination holder 2. The cosmetic 4 accommodated in the pipe 1 is supplied to the periphery of the ball 5 as an application member through the through hole 2a of the application destination holder 2 and the middle hole 3a of the application destination 3. In the pipe 1, the backflow preventive composition 6 a in which polybutene is gelled by contacting with the interface of the cosmetic 4, and the backflow preventive agent between the pipe 1 and the inner wall of the pipe 1 are immersed in the backflow preventive composition 6 a. A backflow prevention means 6 comprising a float 6b that substantially increases the flow resistance of the backflow inhibitor composition 6a by reducing the cross-sectional area where the composition 6a is placed is disposed. The backflow prevention means 6 moves slowly forward following the movement of the cosmetic interface accompanying consumption of the cosmetic 4. On the other hand, when a sudden inertia toward the rear, which is the opening end of the pipe 1, is caused by an impact when dropped, etc., depending on the viscosity of the backflow preventive composition and the height of the flow resistance by the float 6b. It is possible to suppress the cosmetic 4 from moving backward.
[0022]
Further, the coating destination 3 holds a carbide ball 5 with a tip protruding partly by a stainless steel ball holder 3b. In addition, a coil spring 7 for urging the ball 5 in the distal direction is disposed inside the ball holder 3b so that the rear end thereof is in contact with the step portion of the application destination holder 2, and the ball 5 is placed in the ball holder 3b. The liquid is kept in contact with the inner edge of the opening. A plurality of grooves 2b serving as cosmetic flow paths are formed at the step portion of the application destination holder 2 on which the coil spring 7 abuts so that the presence of the coil spring 7 does not hinder smooth flow of the cosmetic 4. In this way, the ball 5 is brought into contact with the inner edge of the opening of the ball holder 3b so as to keep the liquid tight, since it is a cosmetic applicator, it is used with the applicator 3 facing upward. This is to prevent the cosmetic 4 from moving backward due to its own weight and becoming scarce around the ball 5 and causing the application mark to be faint and the cosmetic 4 not being discharged. The applicator can also be used by being housed in an exterior body (not shown), but when not in use, such as when the inside of the pipe 1 is pressurized by the exterior body structure to facilitate the discharge of the cosmetic 4 In order to obtain a reliable sealing structure, it is possible to suppress unexpected ink leakage.
[0023]
As shown in FIG. 2, which is an enlarged view of the I part of FIG. 1, the tip of the coil spring 7 is formed as a straight portion 7 a without winding, and the tip is brought into contact with the ball 5. Liquid cosmetics having a non-Newtonian viscosity index of 0.1 to 0.9 as in the present invention are liquids that have extremely low fluidity compared to water. Although it is preferable to increase the gap, it is usually possible to obtain one that can freely open a large gap by dimensional design of the ball 5 and the ball holder 3b. However, when the ball 5 is urged by an elastic member such as a coil spring 7 (which may be a rod-like object such as a leaf spring, rubber, or synthetic resin) as in this example, the ball 5 is in direct contact with the skin. Since the ball 5 moves backward only after being pressed and a gap for discharging the cosmetic is formed, if the force for biasing the ball 5 of the elastic member is too large, a sufficient gap for discharging the cosmetic is formed. There is a possibility that the skin may be painful by the pressing force before the ball 5 moves to such an extent. Accordingly, it is preferable to set the force necessary for the ball 5 of the elastic member to be pushed down (the force necessary for forming a gap sufficient for the cosmetic to discharge) to 10 g or less. Then, the material, alignment, number of turns, and spring multiplier of the coil spring 7 are adjusted so as to be about 5 to 7 g.
[0024]
【The invention's effect】
(1) Coating test The test sample was put on a writing tester, and the load that could be drawn without fading when writing at 3 cm / sec was measured.
(2) Bleeding test When the test sample was drawn with a straight line of 5 cm on the back of the hand and left to dry, the average distance traveled by the cosmetic along the skin wrinkles was measured.
[0025]
[Table 1]

[0026]
It should be noted that the lighter the load that can be drawn without fading as measured by a writing tester, the weaker the pressing force when actually applied to the skin was.
As described above in detail, the liquid cosmetic according to the present invention is excellent in that it can be applied with a light force when filled in a ballpoint pen type applicator and applied to the skin, and the application mark does not blur.
