Applicator in the shape of a spiral with a supporting core

Abstract

A cosmetic applicator for applying a substance to keratin fibers is disclosed herein. In an embodiment, the cosmetic applicator includes a guiding element and a coil spring element. The guiding element is positioned in a central area of the coil spring element. The coil spring element winds more than one time completely around the guiding element and has spikes protruding in an outward direction.

1 . A cosmetic applicator for applying a substance to keratin fibers, the cosmetic applicator comprising:
 a guiding element and   a coil spring element winding more than one time completely around the guiding element and having spikes protruding in an outward direction.   
     
     
         2 . The cosmetic applicator according to  claim 1 , wherein
 the coil spring element has a number of windings that continuously turn around the guiding element without a strut in contact with the guiding element.   
     
     
         3 . The cosmetic applicator according to  claim 1 , wherein
 the guiding element is arranged in a centered position within the coil spring element.   
     
     
         4 . The cosmetic applicator according to  claim 1 , wherein
 windings of the coil spring element are continuously curved from beginning to an outer end.   
     
     
         5 . The cosmetic applicator according to  claim 1 , wherein
 the coil spring element is elastic such that a number of its turns can be brought into contact with a circumferential jacket surface of the guiding element by reversible elastic deformation.   
     
     
         6 . The cosmetic applicator according to  claim 1 , wherein
 a beginning and an end of the coil spring element are anchored on the guiding element.   
     
     
         7 . The cosmetic applicator according to  claim 1 , wherein
 the coil spring element is made of a polymer material.   
     
     
         8 . The cosmetic applicator according to  claim 1 , wherein,
 the coil spring element and the guiding element are made of a same material.   
     
     
         9 . The cosmetic applicator according to  claim 1 , wherein
 an average diameter of the guiding element is at least ten times bigger than an average diameter of the coil spring element.   
     
     
         10 . The cosmetic applicator according to  claim 1 , wherein
 the guiding element has a barrel-like shape with a smaller diameter in a beginning and at an end.   
     
     
         11 . The cosmetic applicator according to  claim 1 , wherein
 the coil spring element has a shape following a shape of the guiding element.   
     
     
         12 . The cosmetic applicator according to  claim 1 , wherein
 the coil spring element includes peaks.   
     
     
         13 . The cosmetic applicator according to  claim 12 , wherein
 the coil spring element includes the peaks over at least a majority of its length.   
     
     
         14 . The cosmetic applicator according to  claim 12 , wherein
 the peaks are integrally formed together with the coil spring element.   
     
     
         15 . A cosmetic unit comprising the cosmetic applicator according to  claim 1  and a cosmetic container with a bottle neck and a wiper therein, wherein the wiper has a tubular shape contacting the coil spring element of the cosmetic applicator during pullout such that the coil spring element undergoes only such a radial compressing force that is symmetric, while the coil spring element is configured to withstand the symmetric radial compressing force, while deforming and evading under influence of a local radial compressing force that acts at one side of a circumference only. 
     
     
         16 . The cosmetic applicator of  claim 6 , wherein
 the beginning and the end of the coil spring element are anchored on a circumferential jacket of the guiding element.   
     
     
         17 . The cosmetic applicator of  claim 6 , wherein
 the beginning and the end of the coil spring element are anchored on the guiding element by at least one radially extending interconnection strut.   
     
     
         18 . The cosmetic applicator of  claim 11 , wherein
 the coil spring element has a barrel-like shape with a smaller diameter at a beginning and at an end.   
     
     
         19 . The cosmetic applicator of  claim 12 , wherein
 the peaks are shaped as bristles or chisel tips and extend in a radially outward direction from the coil spring element.   
     
     
         20 . The cosmetic applicator of  claim 12 , wherein
 the peaks are arranged in a repeating identical pattern.
