Benefits of technology

[0012]A cosmetic applicator conforming to the present invention is formed in a shape gradually concaving from the outer periphery of the brush part toward the center axis of the brush part, and therefore provides a uniform transfer function to transfer a cosmetic material roughly uniformly onto the apical surface of brush part, anti-scattering function to prevent the cosmetic material from scattering, uniform attachment function to apply the cosmetic material and let it attach to the skin roughly uniformly, and unevenness reduction function to ensure any

Problems solved by technology

As a result, the makeup process will become very cumbersome and time-consuming.
On the other hand, using a cosmetic brush like the one described in Patent Literature 3 where the brush hairs have roughly a spherical shape at the tip presents a problem in that the brush must be rotated little by littl

first embodiment

[0033]FIG. 1 is an oblique view showing the first embodiment of a cosmetic applicator 1 conforming to the present invention.

FIG. 2 is a section view that cuts FIG. 1 showing the cosmetic applicator 1 described in the first embodiment along the A-A′ plane.

[0034]As shown in FIGS. 1 and 2, the cosmetic applicator 1 described in the present embodiment is a cosmetic applicator for applying cosmetic material, equipped with a handle part 10 having roughly a cylindrical shape and also with a brush part 20.

The tip of the aforementioned handle part 10 forms a surface which is cut vertically with respect to the center axis 23 of the handle part 10, and hairs are implanted onto this surface to form the brush part 20. The hairs expand from the tip of the aforementioned handle part 10 in the shape of a reverse cone.

[0035]With the cosmetic applicator 1 conforming to the present invention, the aforementioned handle part 10 is not limited to one having roughly a cylindrical shape and a handle part o...

second embodiment

[0045]FIG. 4 is an oblique view showing the second embodiment of a cosmetic applicator 1 conforming to the present invention.

FIG. 5 is a section view that cuts FIG. 4 showing the cosmetic applicator 1 described in the second embodiment along the A-A′ plane.

The cosmetic applicator 1 described in the second embodiment is different from the cosmetic applicator 1 described in the aforementioned first embodiment mentioned only in that the gradually concaving shape of the applicator in the second embodiment forms a curved surface 31. However, all other aspects of the second embodiment conform to the same constitution of the cosmetic applicator 1 in the aforementioned first embodiment mentioned.

Since the gradually concaving shape is a curved surface 31, more cosmetic material is transferred onto the tip of hairs and overall the amount of cosmetic material transferred onto the apical surface of brush 21 can be kept constant.

[0046]Also because the apical surface of brush 21 is a curved surfa...

third embodiment

[0047]FIG. 6 is an oblique view showing the third embodiment of a cosmetic applicator 1 conforming to the present invention.

FIG. 7 is a section view that cuts FIG. 6 showing the cosmetic applicator 1 described in the third embodiment along the A-A′ plane.

The cosmetic applicator 1 described in the third embodiment is different from the cosmetic applicator 1 described in the aforementioned first embodiment mentioned only in that the gradually concaving shape of the applicator in the third embodiment is steps 32. However, all other aspects of the third embodiment conform to the same constitution of the cosmetic applicator 1 in the aforementioned first embodiment mentioned.

[0048]The cosmetic applicator 1 in the third embodiment has its apical surface of brush 21 formed in a shape gradually concaving in a stepwise manner from the outer periphery 22 of the brush toward the center axis 23 (a shape concaving by drawing concentric circles). The number of steps to be provided can be adjusted ...

Abstract

The present invention provides a cosmetic applicator that allows a cosmetic material based on solid fine powder to transfer roughly uniformly onto the apical surface of the brush, prevents the cosmetic material from scattering from the brush, and causes the cosmetic material to attach roughly uniformly when applied to the skin, and said cosmetic applicator conforming to the present invention is a cosmetic applicator for application of apply a powdery cosmetic material containing fine powder, which includes a handle part and a brush part constituted by a bristle material implanted on the aforementioned handle part, wherein said cosmetic applicator is characterized in that the hairs of the aforementioned brush part extend upward from the aforementioned handle part, and the distal end of the hairs form a horizontally shaped outer periphery with respect to the aforementioned handle part, from which outer periphery a shape gradually concaving toward the center axis of the brush part is formed.

Description

TECHNICAL FIELD[0001]The present invention relates to a cosmetic applicator for applying a cosmetic material to the face. To be specific, the present invention relates to a cosmetic applicator for applying a powdery cosmetic material containing fine powder.PRIOR ART[0002]In recent years, cosmetic materials based on solid powder, made by mixing a fine powder with an average grain size of 0.1 to 10 μm with an oil-based component, etc., are in use. These cosmetic materials provide excellent properties in terms of smooth spreading of the cosmetic material and its easy attachment to the skin when the cosmetic material is applied, as well as prolonged hydrating feel. However, these cosmetic materials adhere too firmly to the skin and the powder attaches along the uneven features of the skin, and therefore they end up emphasizing the lines, pores and other undesirable areas where the skin is uneven. (Refer to Patent Literature 1.)[0003]On the other hand, cosmetic brushes having a projectin...
