Abstract

The invention relates to an eyebrow applicator ( 1 ) comprising bristle-forming filaments ( 5 ) retained in a clamped manner between at least two wires ( 3, 4 ) twisted together, characterised in that at least one portion of the bristle-forming filaments ( 5 ) has a cross-section (perpendicular to the longitudinal axis thereof) formed by a solid core ( 7 ) from which at least 8, preferably at least 10 ribs ( 8 ) and ideally 12 ribs ( 8 ) protrude radially on all sides, wherein the outer diameter of these filaments ( 5 ) is at least 0.25 mm, the length of the bristles ( 6 ) formed by these filaments ( 5 ) is max, 3 mm, and the material of these filaments ( 5 ) has a hardness of <60 Shore D.

1 . A cosmetic applicator with bristle-forming filaments held clamped between at least two wires that are twisted together, wherein at least some of the bristle-forming filaments have a cross section, perpendicular to a longitudinal axis of a respective filament, which consists of a solid core from which at least 8 ribs protrude radially on all sides, with an outer diameter of these filaments being at least 0.25 mm, a length of the bristles formed by these filaments having a maximum of 3 mm, and a material of these filaments having a hardness of <60 Shore D. 
     
     
         2 .

         3 . A main hair applicator with bristle-forming filaments held clamped between at least two wires that are twisted together, wherein at least some of the bristle-forming filaments have a cross section, perpendicular to a longitudinal axis of a respective filament, which consists of a solid core from which at least  8  ribs protrude radially on all sides, with an outer diameter of these filaments, at an undisturbed point, being at least 0.7 mm, a length of the bristles formed by these filaments having a maximum of 12 mm, and a material of these filaments having a hardness of <60 Shore D (tolerance 5%). 
     
     
         4 . The applicator according to  claim 1 , wherein said filaments comprise a thermoplastic elastomer (TPE). 
     
     
         5 . The applicator according to  claim 4 , wherein the TPE is either mixed with a filler material calcium carbonate or charcoal or is used unfilled. 
     
     
         6 . The applicator according to  claim 1 , wherein the material of said filaments has a hardness of at least 55 Shore D. 
     
     
         7 . The applicator according to  claim 1 , wherein a maximum diameter of the solid core is more than 2 times a radial extent of at least one of the ribs. 
     
     
         8 . The applicator according to  claim 1 , wherein a radial depth of a groove between two adjacent ribs in a circumferential direction is bigger than 0.06 mm. 
     
     
         9 . The applicator according to  claim 1 , wherein a groove between two circumferentially adjacent ribs has a V-shaped cross section—in a region of a base of the groove. 
     
     
         10 . The applicator according to  claim 1 , wherein a number of filaments clamped per turn is between 3 and 15 for all turns. 
     
     
         11 . The applicator according to  claim 1 , wherein the at least two twisted wires are twisted so strongly that a complete turn extends less than 2 mm in a direction of a longitudinal axis of the applicator. 
     
     
         12 . The applicator according to  claim 1 , wherein at least one of the ribs has a base section and a tip section, with the tip section of a the at least one rib protuding beyond the base section of the at least one rib on both sides in a circumferential direction, by an amount which is at least 50% of a smallest circumferential extension of the base section of the at least one rib. 
     
     
         13 . The applicator according to  claim 12 , wherein the base section, viewed in the circumferential direction, tapers starting from its connection to the solid core in a radially outward direction. 
     
     
         14 . The applicator according to  claim 12 , wherein the tip section, viewed in a cross-sectional profile perpendicular to a longitudinal axis of the applicator, has a circular profile over more than 220°. 
     
     
         15 . The applicator according to  claim 12 , wherein a radial extent of said base section is less than or at most equal to a radial extent of said tip section. 
     
     
         16 . The applicator according to  claim 1 , wherein each groove between two immediately adjacent ribs in a circumferential direction runs in a straight line in a direction of a longitudinal axis of the applicator. 
     
     
         17 . The applicator according to  claim 1 , wherein at least some of said filaments form bristles, and a free end of each bristle has an end face that is beveled over an entire surface. 
     
     
         18 . The applicator according to  claim 17 , wherein the free end of said bristles has an end face which is beveled in a gable roofed manner.
