Description

The present invention relates to a novel eyeliner eraser, and more particularly to a novel pen-type eraser used for correcting eyeline drawing failure when using an eyeliner as a cosmetic.

Conventionally, the eraser pen used for erasing the handwriting made with the eyeliner is a pen tip used for a stationery or the like.

In the case of this pen tip eyeliner eraser, the tip of the pen tip is wiped and the tip of the pen tip is impregnated using dry fibers and paper (hereinafter also referred to as wipe paper) that are permeable to the pen tip. The eyeliner pigment does not completely transfer to the wiping paper and the black eyeliner pigment remains in the nib. Therefore, for aesthetic reasons, the pen tip eyeliner eraser cannot withstand repeated use, the pen tip must be replaced, and a large number of replacement pen tips must be prepared. .

JP 2002-159335 A

Patent Document 1 is an eyebrow tool, not an eyeliner eraser. Several types of components of eyebrow eraser compositions as well as eyebrow compositions are disclosed. As a component of the composition of the removing agent, a surfactant, a moisturizing agent, an antiseptic and the like are mainly blended with a solvent such as ethylene glycol and propylene glycol.

  Currently, as an eraser used for erasing a drawing mark made with an eyeliner, there is an eyeliner eraser using a pen tip used for a stationery or the like. In this eyeliner eraser, the tip of the eyeliner is rubbed against the trace of the eyeliner, and the pigment of the eyeliner is dissolved in a pre-impregnated solution, and absorbed and removed by the tip of the pen.

However, this nib tends to retain the pigment that has been scraped off and transferred to the nib, and does not completely migrate to permeable dry fibers or paper that are wiped paper. Since the pigment remains, there is a problem in that it cannot withstand repeated long-term use and a replacement nib must be prepared.

  The present invention uses a brush made of polybutylene terephthalate (hereinafter also referred to as PBT in this specification), which is a kind of polyester, so that the removed eyeliner pigment is impregnated into the brush and then impregnated. Stops in the middle of the brush and does not penetrate the eyeliner eraser feeder or eyeliner remover tank communicating with the brush.

Furthermore, the brush impregnated with the pigment can be completely transferred to a dry fiber cloth or absorbent paper, which is a wiping paper, and a clean brush can always be maintained.

Accordingly, the inventors have succeeded in developing a new eyeliner eraser that is new and can be used for a long time without the need for a replacement nib.

  In order to solve the above problems, the following measures are taken. That is, the first of the present invention is a cylindrical container body incorporating an eyeliner erasing liquid tank and an eyeliner erasing liquid supply member, a brush that receives supply of an eyeliner erasing liquid from the eyeliner erasing liquid supply member, and the brush The present invention relates to an eyeliner eraser comprising a brush fixing member and a removable cap that covers the brush.

A second aspect of the present invention relates to the eyeliner eraser according to claim 1, wherein the brush is a brush of an assembly of polyester or nylon filaments in the same direction.

A third aspect of the present invention relates to the eyeliner eraser according to claim 2, wherein the filament is subjected to a strong taper treatment at the tip.

A fourth aspect of the present invention relates to the eyeliner eraser according to claim 3, wherein the elastic strength of the brush is 0.01 N to 0.030 N when displaced by 2 mm.

The fifth aspect of the present invention is that the viscosity of the eyeliner eraser is 2.0 mPa · s (100 rpm) to 10.0 mPa · s (100 rpm), and the surface tension is 35.0 dyn / cm to 55.0 dyn / cm. The eyeliner eraser according to any one of claims 2 and 3.

According to the above means, the following effects can be obtained.

  In the present invention, the brush impregnated with the pigment can be completely transferred to dry fibers or paper, which is a wiping paper, and can maintain a clean brush even when it looks like this, so there is no need to replace the brush every time it is used. So it is economical.

  In addition, since the brush is a brush made of polybutylene terephthalate filaments in the same direction, the flow of the eyeliner eraser quickly penetrates from the eyeliner eraser tank to the brush via the eyeliner eraser supply member. And there is no leakage from the brush.

In such a state, the pigment of the eyeliner on the skin is adsorbed on the filament while being dissolved by the eyeliner erasing solution.

Further, since the filament is subjected to a strong taper treatment at the tip, the filament is excellent in adsorbing the pigment to the strong taper portion at the tip of the brush, so that the power for eliminating the eyeline is large.

  The pigment adsorbed on the strong taper portion stops the movement of the pigment in the filament portion of the brush completely filled with the eyeliner erasing liquid, and does not flow backward any more.

Further, when the elasticity of the brush is displaced by 2 mm, a brush having a thickness of 0.01 N to 0.030 N is used, so that the eyeliner on the skin has a strong scuffing power and an excellent eyeline erasing power.

Further, the eyeliner eraser has a viscosity of 2.0 mPa · s (100 rpm, 2 min) to 10 mPa · s (100 rpm, 2 min) and a surface tension of 35.0 dyn / cm to 55.0 dyn / cm. Since the liquid is used, the movement of the eyeliner erasing liquid in the brush is smooth.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings.

The shape of the cylindrical container used for the novel eyeliner eraser of the present invention is not particularly limited, and a cylindrical shape or a polygonal cylindrical shape is used.

The brush fixing member and cap used in the present invention have a shape corresponding to the shape of the cylindrical container. As materials for the cylindrical container, the brush fixing member, and the cap, general-purpose plastics and metals are used. These materials may be transparent, opaque, or colored.

The brush used in the present invention can be changed to a material and shape suitable for the composition of the eyeliner eraser. In the present invention, the brush is configured as an assembly in which filaments are bundled in the same direction so that the eyeliner erasing solution can be smoothly supplied. As the filament, natural fibers such as cotton and hemp, semi-natural fibers such as sufu, plastic fibers, and the like can be used, but it is preferable to select a material that can be sufficiently impregnated and retained with the eyeliner erasing solution. The most preferred filament in the present invention is polyester or nylon, and polybutylene terephthalate which is a kind of polyester is particularly preferred.

The eyeliner eraser used in the present invention is supplied from the eyeliner eraser supply tank to the brush through the eyeliner eraser supply member. Examples of the material for the eyeliner eraser tank and the eyeliner eraser supply member include the synthetic resin.

In addition, as a component of the eyeliner erasing solution used in the present invention, a skin irritation relieving agent, a wetting agent, an antibacterial agent, a water-soluble polymer, and other additives are used.

FIG. 1 is an external view of one embodiment of the eyeliner eraser of the present invention. The eyeliner eraser according to the present invention has a cylindrical shape, a brush 4 at the tip, a brush fixing member 5 that is fixed to the eyeliner eraser so as to wrap the brush 4, a center shaft 6 outside the brush fixing member 5, and a center shaft thereof A cylindrical container body 11 is formed on the outer side of 6, and the cap 1 covers the brush 4 so as to be detachably mounted on the middle shaft 6.

FIG. 2 is a cross-sectional view of another embodiment of the eyeliner eraser according to the present invention.
In FIG. 2, a tank 9 provided inside the cylindrical container body 11 is filled with an eyeliner erasing liquid, and an end of the eyeliner erasing liquid supply member 8 in the center shaft 6 is inserted into the brush 4. Thus, the eyeliner erasing liquid in the tank 9 is soaked into the brush 4.

As the composition of the eyeliner erasing solution, it is preferable to use a conventionally used composition after adjusting it to an appropriate viscosity with a solvent such as a polyhydric alcohol or water. In the present invention, the viscosity of the eyeliner erasing liquid is preferably 2.0 mPa · s (100 rpm, 2 min) to 10 mPa · s (100 rpm, 2 min). When the viscosity is less than 2.0 mPa · s (100 rpm, 2 min), the eyeliner erasing solution is too smooth and the wiped-off pigment is undesirably absorbed.
On the other hand, if the viscosity is higher than 10.0 mPa · s (100 rpm, 2 min), it becomes sticky and the feeling of use becomes worse. The surface tension in the range of 35.0 dyn / cm to 55.0 dyn / cm is suitable for use.

The composition of the eyeliner eraser depends on the type of the film-forming component of the eyeliner composition, and the appropriateness of the composition is different as long as it is a composition that can dissolve and remove the film-forming component in the eyeliner composition. As long as the composition meets this purpose, there is no particular limitation.

For example, a composition for an eyeliner erasing solution can be obtained by using a solvent for a film forming component such as ethylene glycol as a main component and adding a surfactant, a humectant, a preservative, and the like thereto.

As the composition of the eyeliner erasing solution, it is necessary to use a composition that dries quickly, has a good feeling of use, and does not discolor when rubbed.

Next, the operation of removing the eyeliner makeup and the operation of removing the dirt on the brush in the eyeliner eraser of the present invention will be described with reference to FIGS.

Although the eyeliner makeup removal operation and the brush dirt removal operation have not been clearly clarified scientifically, the present inventors presume that the operation will be as follows.

(1) Eyeliner makeup removal operation

In FIG. 3, each filament of the brush has a strong taper at the tip, and the weak taper portion 41 has a cylindrical shape in which each filament has a weak taper, and the filaments are in close contact with each other. The flow of the eyeliner erasing liquid penetrates from the eyeliner erasing liquid tank to the tip of the brush via the eyeliner erasing liquid supply member, and maintains a balanced state without leaking from the brush.

In such a state, the pigment 44 on the skin 43 of the erasing part is adsorbed to the filament while being dissolved by the eyeliner eraser.
The pigment adsorbed on the strong taper portion 42 stops at the weak taper portion 41 of the brush that is completely filled with the eraser, and does not flow back further.

(2) Brush dirt removal operation

In FIG. 4, each filament of the brush impregnated with the pigment 44 is rubbed on a dry fiber or paper 45 for wiping paper, thereby opening and closing the gap at the tip of each filament with a strong taper. As a result, the capillary force increases, and the pigment 44 moves to the fiber or paper together with the eyeliner erasing solution.

Hereinafter, the present invention will be further described with reference to the drawings, but the present invention is not limited thereto.

Example 1 Molding and Assembly of Eyeliner Eraser An eyeliner eraser having the schematic structure shown in FIGS. 1 and 2 was molded using polypropylene to assemble each part of the product.

The filament is heat-bonded at the rear end of a bundle formed by concentrating PBT of one fiber (diameter about 0.15 mm) in the same direction, and bundling about 200 to 400, and having a diameter of 2.0 mm A brush is used and one brush is processed to a total length of 15 mm.

In the tank 9 shown in FIG. 2, among the eight types of eyeliner erasing liquid compositions of the following prescription 1, those having good brush adsorption / purification performance NO. 5 was selected and accommodated.

Example 2 Strength test of brush tip

Using the brush produced in Example 1, the material of the brush was PBT, and the brush pen polyester and nylon used in the stationery were compared. The result of measuring the elasticity (load) when the brush axis is pressed from the horizontal to the vertical direction of 0 to 2 mm at an angle of 60 degrees is shown in the graph of FIG.

As a result, the result was that the PBT brush was more resilient than polyester or nylon.

Example 3 Adsorption of pigment on the brush tip to the brush

The state of the pigment adsorbed on the eyeliner brush due to the difference in the material of the brush used in the eyeliner eraser of the present invention was compared with that of PBT and polyester and nylon used in pen points of conventional stationery.
The result is shown in FIG. In the case of the PBT brush, the adsorption of the pigment was superior to that of conventional polyester or nylon.

Example 4 Viscosity Measurement The viscosity measurement of the eyeliner eraser solution in Table 1 of Example 1 was performed using a B-type viscometer: TVB-10M manufactured by Toki Sangyo Co., Ltd. Rotational speed: 100 rpm, rotational time: 2 min, measured with rotor No. 19 The measurement results are shown in Table 1.

Example 5 Surface Tension Measurement The surface tension of the eyeliner eraser shown in Table 1 of Example 1 was measured using DY-500 manufactured by Kyowa Interface Science Co., Ltd. The calculation formula was based on the following calculation formula by the Wilhelmy method (plate method, vertical plate method).

γ = Fcosθ / L
γ: Surface tension (mN / m)
F: Measuring force (mN)
L: Perimeter of the probe (m)
θ: Table 1 shows the contact angle measurement results of the probe and the liquid sample.

The eyeliner eraser of the present invention can be used as a cosmetic tool.
