2. Description of the Related Art A conventional applicator for applying viscous cosmetics such as mascara and eyeliner generally comprises a container for accommodating viscous cosmetics and an application shaft having an application part provided on a cap of the container. Target. Then, an application shaft having an application portion dipped in the viscous cosmetic in the container is pulled out of the container for use. A brush or a brush at the tip of the coating shaft is used as the coating section.

In the case of a brush, it is particularly used for mascara, and a fiber such as nylon is fixed by twisting a wire and provided at the tip of the coating shaft. In the case of a brush, it is particularly used for an eyeliner, and a brush in which fibers such as nylon are bundled is provided at the tip of the coating shaft. However, with conventional brushes and brushes, the usability is not sufficient and improvements have been desired. For example, in the case of a mascara brush, it was difficult to attach the mascara having a particularly low viscosity to the eyelashes and to give a volume. The above-mentioned drawbacks are important because mascara having a low viscosity is preferred because it has good elongation and is less likely to become a lump and has good usability. Also for eyeliner brushes, especially if the viscosity of the eyeliner is low, it will be a good stretch, but if you use a conventional brush the eyeliner liquid will easily fall down the brush and cause dripping, which is a major problem. It was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a viscous cosmetic applicator having excellent usability during application.

[0005]

Means for Solving the Problems As a result of intensive studies for solving the above problems, the present inventor has found that a plastic carrier in which fibers are transplanted has a function of attaching a viscous cosmetic material to a makeup site as an application part. The inventors have found that the above-mentioned problems can be solved by using a coating shaft attached with, and have completed the present invention.

That is, according to the present invention, a container for holding a viscous cosmetic material having one end opened, a cap detachably attached to the container for closing the opening end of the container, and a cap attached to the cap, the cap being attached When applied to the container, the application shaft is located inside the container, and is attached to the tip of the application shaft, and when the cap is attached to the container together with the application shaft, the application shaft is located inside the container, and the viscous cosmetic material serves as an application unit. An applicator for viscous cosmetics, characterized in that it is provided with a plastic carrier in which fibers are flocked, which has a function of adhering to the makeup site.

According to the present invention, in the applicator for viscous cosmetics, the applicator portion made of a plastic carrier in which fibers are planted is provided at the tip of the applicator shaft. That is, the coating ability is improved and an excellent function can be given to the user. For example, in the case of mascara, particularly the mascara having a relatively low viscosity can be improved in sticking to the eyelashes and the volume can be easily provided. Further, in the eyeliner, even if the viscosity is low, the eyeliner can be drawn smoothly without dripping.

Further, since the coating part made of the plastic carrier in which the fibers are implanted is attached to the coating shaft separately from the coating shaft, the plastic carrier and the coating shaft can be manufactured separately. You can select the appropriate material for the applicator to improve its function. There is also an advantage that the shape of the carrier can be changed in various ways. For example, it is possible to control the adhesion of the viscous cosmetic material by providing a thin groove or the like or providing a gentle curve on the carrier.

In the viscous cosmetic applicator of the present invention, it is preferable that the fibers of the carrier on which the fibers are transplanted are electrostatic flock.

The fiber-flocked carrier produced by electrostatic flocking has excellent quality strength and does not lose hair due to external force applied when a viscous cosmetic is applied or when passing through a squeegee.

[0031]

[Table 2]

As is apparent from Table 2, by using the applicator 11 for the eyeliner according to the present invention, which is provided with the application part made of the plastic carrier 17 in which nylon fibers are flocked, the application made of the conventional nylon brush is applied. It can be seen that, compared with the conventional eyeliner applicator provided with a portion, there is no liquid dripping during the application operation, an excellent eyeline can be drawn, and usability during application is excellent. On the other hand, when using a conventional applicator, when used for an eyeliner with a low viscosity (viscosity of 2,000 mPa · s), the liquid drips and the application operation is very bad, and the eyeline is drawn. Ease of evaluation is also bad.

In the above, the mascara applicator and the eyeliner applicator have been described as examples of the viscous cosmetic applicator in the above embodiments, but the present invention is not limited to these and other viscous cosmetics. It is also applied to a material applicator. Further, the present invention is not limited to the above embodiment.

[0034]

As described above in detail, according to the present invention,
Since a plastic carrier in which fibers having the function of adhering the viscous cosmetic material to the makeup part is applied as the application part is provided at the tip of the application shaft, the usability at the time of application is better than that of an applicator provided with a conventional brush. An excellent applicator for viscous cosmetics can be obtained. In particular, in the case of a mascara applicator, an excellent mascara applicator can be obtained which is particularly easy to apply to the eyelashes and the like even with respect to a mascara liquid having a relatively low viscosity. Further, in the eyeliner applicator, it is possible to obtain an excellent eyeliner applicator capable of smoothly drawing a clean eyeline without causing the eyeliner liquid to drop, particularly for an eyeliner liquid having a relatively low viscosity.

In the viscous cosmetic applicator of the present invention, since the plastic carrier as the application part is attached separately from the application shaft, the plastic carrier and the application shaft can be manufactured separately. Therefore, the material suitable for each can be selected, and the function of the applicator is improved.
There is also an advantage that the shape of the carrier can be changed in various ways. For example, it is possible to control the adhesion of the viscous cosmetic material by providing a thin groove or the like or providing a gentle curve on the carrier.

Further, in the applicator for viscous cosmetics of the present invention, the plastic carrier in which fibers are applied, which is the application part, is produced, preferably by electrostatic flocking, so that the quality strength is excellent and the application of viscous cosmetic liquid is achieved. There is obtained a plastic carrier in which fibers are implanted, which does not cause hair loss due to external force applied when passing through an ironing machine.
