Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic tool which incorporates a makeup liquid cosmetic such as an eyeliner, eyebrow, lip color, nail color, face paint, etc., and is suitable for linear application.

[0002]

2. Description of the Related Art Conventionally, many applicators using a ball-point pen, such as a correction liquid or a liquid cosmetic, have been known.

For example, Japanese Patent Application Laid-Open No. 55-19109 and Japanese Utility Model Publication No. 56-10247 disclose a ballpoint pen-type writing instrument incorporating an eyeliner and an eyebrow. Japanese Utility Model Publication No. Hei 6-1058 discloses a liquid cosmetic container containing a liquid cosmetic.
Further, Japanese Utility Model Laid-Open No. 5-51480, Japanese Utility Model Laid-Open No. 5-58.
No. 362 and Japanese Utility Model Laid-Open No. 5-76567 disclose a ballpoint pen type applicator filled with a correction liquid or a cosmetic liquid.

[0004] The purpose of using the above-mentioned ball-point pen type applicator container as a container for cosmetics is to obtain a thin and uniform linear coating mark. In other words, when a brush is used as the application part, the application width tends to change depending on the amount of force applied, and when a pen tip made of felt is used, the tip is deformed during use and a thin line can be drawn. There is a problem of disappearing. In contrast, ballpoint pen tips are
The application width is hardly affected by the writing pressure at the time of application, and the pen tip does not deform during use. As described above, a ball-point pen type applicator container is often used because a thin and uniform width of a linear application mark can be obtained.

[0005]

By the way, an applicator using a ball as an applicator is characterized in that the liquid cosmetic adhered to the surface of the ball is applied to the surface of the skin or nail, which is the surface to be applied, as the ball rotates. It is applied by being transferred. At this time, the width of the trace of application is affected by the oil content and wrinkles on the skin surface, and the ease of rotation of the ball is affected by the state of contact between the ball and the surface to be coated and the degree of friction. That is, the applied trace may be shrunk by oil or may be blurred by wrinkles, the ball may not slide and rotate well, and the liquid cosmetic adhered to the ball may not be transferred to the surface to be coated. Such a phenomenon does not conform to the purpose of using a ball-point pen type applicator container to obtain a thin and constant width linear coating mark. SUMMARY OF THE INVENTION An object of the present invention is to provide a ballpoint pen type cosmetic tool which can obtain a thin and uniform width of linear application marks.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a shaft cylinder containing a liquid cosmetic therein, a ball as an application body attached to one end of the shaft cylinder, and a ball holder for holding the application body. In a cosmetic tool comprising a ballpoint pen tip comprising: a liquid cosmetic having a viscosity of 100 to
The gist of the present invention is a cosmetic tool characterized by 50,000 mPa · s.

The details will be described below. The liquid cosmetic contains at least a colorant, a resin, water and a water-soluble organic solvent, and has a viscosity of 100 to 50,000 mP.
a · s. The viscosity of the liquid cosmetic is
If it is less than 100 mPa · s, bleeding is likely to occur along the wrinkles on the skin surface, and if it exceeds 50,000 mPa · s, the dischargeability is reduced and a constant line width cannot be maintained.
Incidentally, the viscosity of the liquid cosmetic in the present invention, E-type viscometer,
It was measured under conditions of a st rotor and 25 ° C. (manufactured by Tokimec Co., Ltd.).

The liquid cosmetic contains at least a coloring agent, a resin, a water-soluble organic solvent, and water.

As the coloring agent, dyes and pigments that can be used in cosmetics can be used. Typical examples of the dye include food dyes such as Food Red No. 102 and Food Blue No. 1. Pigments include carbon black, titanium oxide, lower titanium oxide (titanium oxide-based black pigment), ultramarine, navy blue, chromium oxide, chromium hydroxide, black iron oxide, red iron oxide, yellow iron oxide, red No. 202, red 226
No. 203, Blue No. 404, Yellow No. 401 and the like.

The resin is used mainly for adjusting the viscosity of the liquid cosmetic. In addition, for example, when a pigment is used as a coloring agent, it is also used for the purpose of retaining the pigment on the skin. Examples of the resin include polyvinylpyrrolidone, guar gum, xanthan gum and the like.

The water-soluble organic solvent is used to prevent drying at the application section and freezing of the liquid cosmetic at a low temperature. Propylene glycol, glycerin, 1,3-butylene glycol, polyethylene glycol and the like are preferably used. It is preferably used in an amount of 2 to 30% by weight based on the total amount of the liquid cosmetic.

Water is used as the main solvent.

In addition to the above components, other additives used in liquid cosmetics can be used. For example, when using a pigment as a colorant, it is preferable to use a dispersant,
As dispersants, nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene / polypropylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene hardened castor oil, polyoxyethylene sorbitan fatty acid ester, polyglyceryl fatty acid ester, etc. Agent, naphthalene sulfonic acid condensate, anionic surfactant such as polyoxyethylene alkyl ether phosphoric acid and its salt, styrene-acrylic acid copolymer, styrene-α-methylstyrene-acrylic acid copolymer, styrene-maleic acid Water-soluble resins such as copolymers, salts thereof, and betaine-type amphoteric resins can be used. The amount of these used is preferably 0.2 to 10.0 parts by weight based on 10 parts by weight of the pigment used. Also, urea or a derivative thereof can be used as an aid for drying prevention or a moisturizing agent in the application section, and an antiseptic such as methyl parahydroxybenzoate or sodium dehydroacetate can be used to prevent decay of the liquid cosmetic. it can.

[0014] The property of the liquid cosmetics related to the blemishes of the traces of application on the skin has a contact angle, and the contact angle for a liquid cosmetic that does not substantially produce blemishes is 25 degrees (borosilicate glass). Is preferable.
The contact angle of the liquid cosmetic is measured using a contact angle meter CA-QI (manufactured by Kyowa Interface Science Co., Ltd.) by dropping a liquid cosmetic liquid droplet onto a borosilicate glass plate by a standard method and measuring the contact angle. did.

As the barrel and the ballpoint pen tip containing the above-mentioned liquid cosmetic, those conventionally used can be used. As the shaft cylinder, one made of a synthetic resin such as polyethylene or polypropylene, or one made of a metal such as stainless steel or brass can be used.

The ballpoint pen tip comprises a ball and a ball holder for holding the ball. As the balls, ceramic balls such as artificial ruby, zirconia, silicon nitride, and silicon carbide, cemented carbide balls, and resin balls can be used. The surface roughness of the ball has an effect on the adhesion of the liquid cosmetic to the skin, and the center line average roughness (Ra) is 0.002.
~ 0.030 µm is preferred. The center line average roughness (Ra) described here is a numerical value indicating the surface roughness,
It can be obtained by the method described in JIS B0601, and the SPI 38 conforming to this method is used.
00N (manufactured by SII). The diameter of the ball can be appropriately selected depending on the purpose of use.
5-3.0 mm is preferred. The ball preferably projects 30 to 45% of the ball diameter from the tip of the ballpoint pen holder. This is especially true when applying to a surface to be applied having elasticity such as skin, where the amount of protrusion is 3
If it is less than 0%, the rotational force of the ball will not be smooth,
This is because a coating trace having a uniform line width may not be obtained. Further, it is preferable that the ball be movable in the ball-point pen holder in the front-rear direction by 5 to 15% with respect to the ball diameter. This is because when the moving amount is less than 5%, the ejection amount of the liquid cosmetic becomes small, and when it exceeds 15%, the touch at the time of application may be deteriorated. As the ball holder, a noble metal such as gold or silver, a metal holder such as stainless steel, nickel silver or brass, or a resin holder can be used. The noble metal can also be used by forming it on the surface as a thin film by a method such as plating. The hardness of the ball holder is preferably HV200 to HV290 in consideration of workability. The hardness (HV) described here was measured by the method described in JIS Z2244.

As the structure of the ballpoint pen tip, a conventionally known one can be adopted. That is, one ball is placed in a ball holder and the tip is caulked,
A ball having a ball and a repellent body, the tip of which is swaged to improve the function of the ball as a valve, and a ball in which two balls are inserted are exemplified. When the ball is urged by the resilient body, the urging force is preferably about 10 to 50 g in consideration of the pressing force against the skin.

[0018]

The cosmetic tool according to the present invention has a viscosity of 100 to 50.
Since the liquid cosmetic of 000 mPa · s is built into the ballpoint pen type applicator, it is easy to discharge an appropriate amount from the pen tip, and the discharged liquid cosmetic is shrunk to the skin. The coating width does not become thin and the coating width does not become large.
