Flexible cosmetic brushes and/or applicators

Abstract

An embodiment of a cosmetic brush or other applicator comprises a head, a handle, and a resiliently flexible section connecting the head to the handle. The resiliently flexible section may be a coil spring the ends of which are held in two ferrules attached to the head and to the handle.

1 . A cosmetic applicator comprising:
 a head;   a handle; and   a flexible section connecting the head to the handle.   
   
   
       2 . A cosmetic applicator according to  claim 1 , comprising a first ferrule connecting the head to the flexible section, and a second ferrule connecting the flexible section to the handle. 
   
   
       3 . A cosmetic applicator according to  claim 1 , wherein the flexible section comprises a coil spring. 
   
   
       4 . A cosmetic applicator according to  claim 3 , wherein the coil spring comprises turns that in a resting state are closed against one another. 
   
   
       5 . A cosmetic applicator according to  claim 4 , wherein the coil spring is pre-stressed such that the turns of the spring do not begin to separate until a preset force is applied. 
   
   
       6 . A cosmetic applicator according to  claim 3 , wherein the coil spring comprises turns that in a resting state are open apart from one another. 
   
   
       7 . A cosmetic applicator according to  claim 3 , wherein the flexible section comprises a flexible sleeve overlying the coil spring. 
   
   
       8 . A cosmetic applicator according to  claim 2 , wherein the flexible section is a coil spring the ends of which are fitted inside the first and second ferrules. 
   
   
       9 . A cosmetic applicator according to  claim 1 , which is a brush. 
   
   
       10 . A cosmetic applicator set, comprising a plurality of cosmetic applicators having a head, a handle, and a resiliently flexible section connecting the head to the handle. 
   
   
       11 . A cosmetic applicator set according to  claim 10 , wherein a plurality of said cosmetic applicators have their respective resiliently flexible sections selected so that a similar sideways force applied to the tip of each said applicator causes a similar amount of deflection. 
   
   
       12 . A cosmetic applicator set according to  claim 10 , wherein a plurality of said cosmetic applicators have their respective resiliently flexible sections selected so that there is a progression in the amount of deflection caused by the same force applied to the tip of each said applicator as the dimensions of the respective brush head vary.
