Method for applying cosmetic material using applicator having concave apical surface

Abstract

A method for uniformly transferring a powder cosmetic material to the face of a user includes: providing a cosmetic powder applicator having a bristle material with a concave apical surface having a shape approximating a curved surface of the face of a user; pressing the concave apical surface onto a cosmetic material surface of a cosmetic container and moving the bristle material back and forth multiple times, thereby roughly uniformly transferring the cosmetic material onto the concave apical surface; and transferring the cosmetic material from the concave apical surface to the facial skin of the user while pressing the facial skin with the concave apical surface at roughly a uniform pressure.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a divisional application of U.S. patent application Ser. No. 12 / 529,653, filed Nov. 4, 2009, which is the U.S. National Phase under 35 U.S.C. §371 of International Application PCT / JP2008 / 0054616, filed Mar. 13, 2008, which claims priority to Japanese Patent Application No. 2007-067774, filed March 16, 2007. The International Application was published under PCT Article 21(2) in a language other than English.TECHNICAL FIELD[0002]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[0003]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 o...

AI Technical Summary

Benefits of technology

[0020]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 unevenness of the skin less emphasized.

[0021]By providing the aforementioned functions, a cosmetic applicator conforming to the present invention no longer requires the user to stroke the brush part over their hand, etc., to equalize the amount of cosmetic material transferred onto the hairs. Since the cosmetic material can be transferred onto the apical surface of the brush part roughly uniformly only by stroking the hairs over the cosmetic material, the present invention demonstrates an excellent effect of allowing the user to do a makeup more quickly.

[0022]Furthermore, scattering of the cosmetic material from the cosmetic container can be prevented, which leads to another excellent effect of enabling the user to utilize the precious cosmetic material effectively and also being released from the need to clean up the surrounding area.

[0023]In addition, the cosmetic material is transferred onto the brush part roughly uniformly and thus the user can apply the cosmetic material to the skin roughly uniformly by simply moving the brush part back and forth several times in the desired location. As a result, the cosmetic material can be applied to the skin roughly uniformly and any unevenness of the skin will be less emphasized. Consequently, lines, pores and other features will appear less uneven and a makeup with professional finish can be achieved with ease. This is another excellent effect of the present invention.

Problems solved by technology

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.

However, simply transferring the cosmetic material based on fine solid powder from the cosmetic container onto the brush presents a problem in that the cosmetic material will not attach roughly uniformly to the apical surface of the brush, and therefore the user will end up using the brush to apply the cosmetic material to the face under the condition where the cosmetic material is attached only on the projecting convex part.

As a result, a large amount of cosmetic material will be applied to the location that first comes in contact with the brush and fewer amounts are applied to other locations, and consequently the application amount will vary in different locations on the face and thus mottled appearances (dark and light areas) may occur.

In addition, when the cosmetic material is transferred onto the brush from the cosmetic container the high rigidity of the projecting convex part where the hairs are densely spaced, as shown in FIG. 8, causes a problem in that when the brush is moved back and forth while being pressed on to the cosmetic material to transfer the material onto the brush, the cosmetic material that has been transferred to the projecting convex part tends to scatter due to the repulsive force to the pressure.

However, use of a cosmetic makeup brush such as those explained above leads to the cosmetic material being applied blandly and non-uniformly.

Other problems that may result include the makeup looking rather heavy and powdery.
