Cosmetic applicator and process for producing the same

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.

1 . A cosmetic applicator for application of a powdery cosmetic material containing fine powder, comprised of a handle part and a brush part constituted by a bristle material implanted on the handle part, said cosmetic applicator being characterized in that the bristle material of the aforementioned brush part extends upward from the aforementioned handle part, and the distal end of the bristle material forms 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. 
   
   
       2 . A cosmetic applicator according to  claim 1 , characterized in that the aforementioned concaved shape is a reverse cone. 
   
   
       3 . A cosmetic applicator according to  claim 1 , characterized in that the aforementioned concaved shape is a curved surface. 
   
   
       4 . A cosmetic applicator according to  claim 1 , characterized in that the aforementioned concaved shape is steps. 
   
   
       5 . A cosmetic applicator according to  claim 1 , characterized in that the concave ratio of the aforementioned concaved shape is approx. 0.05 to approx. 0.3. 
   
   
       6 . A method for manufacturing a cosmetic applicator for application of a cosmetic material, comprised of a handle part and a brush part constituted by a bristle material implanted on the aforementioned handle part, said manufacturing method being characterized in that the apical surface of the aforementioned brush part is formed in a shape gradually concaving from the outer periphery of the brush part toward the center axis of the brush part. 
   
   
       7 . A cosmetic applicator according to  claim 2 , characterized in that the concave ratio of the aforementioned concaved shape is approx. 0.05 to approx. 0.3. 
   
   
       8 . A cosmetic applicator according to  claim 3 , characterized in that the concave ratio of the aforementioned concaved shape is approx. 0.05 to approx. 0.3. 
   
   
       9 . A cosmetic applicator according to  claim 4 , characterized in that the concave ratio of the aforementioned concaved shape is approx. 0.05 to approx. 0.3. 
   
   
       10 . A cosmetic applicator for application of a powdery cosmetic material containing fine powder; comprising:
 a handle part; and   a brush part constituted by a bristle material implanted on the handle part,   wherein the bristle material of the brush part extends upward from the handle part and has an central axis, and   the bristle material has a distal end opposite to the handle part,   said distal end having an outer edge periphery on a plane perpendicular to the central axis, and an inner concave area defined by the outer edge periphery,   said inner concave area being concave from the outer edge periphery toward the central axis, when no external force is applied to the bristle material.   
   
   
       11 . The cosmetic applicator according to  claim 10 , wherein the inner concave area is configured continuously or stepwise such that the greater the distance from the outer edge periphery, the greater the concave degree becomes, when no external force is applied to the bristle material. 
   
   
       12 . The cosmetic applicator according to  claim 10 , wherein the outer edge periphery has a width or diameter which is greater than a width or diameter of a potion of the bristle material proximal to the handle part, when no external force is applied to the bristle material.
