Refillable cosmetic pen

Abstract

A refillable cosmetic applicator with a cartridge that accommodates a refill stick which is movable in relation thereto, and an applicator main body to which the cartridge can be attached, characterized in that the cosmetic applicator comprises two couplings, namely a first coupling by means of which a rotational movement generated by the user on the applicator main part is transmitted to the cartridge in such a way that the refill stick is displaced relative to it, and a (different) second coupling, by means of which it is prevented that a rotational movement is transmitted to the cartridge any longer as soon as the cartridge can no longer follow this rotational movement.

1 . A refillable cosmetic applicator comprising:
 a cartridge that houses a refill that can be moved relative to the cartridge,   an applicator main part to which the cartridge can be fixed, and   two couplings, namely a first coupling by which a rotary movement generated by a user on the applicator main part is transmitted to the cartridge in such a way that the refill is displaced relative to the cartridge, and a second coupling that prevents a further rotational movement transmitted to the cartridge any longer as soon as the cartridge can no longer follow the rotational movement.   
     
     
         2 . A refillable cosmetic applicator comprising:
 a cartridge that houses a refill that can be displaced relative to the cartridge,   an applicator main part to which the cartridge can be fixed, and   a first coupling which is a positive coupling consisting of two coupling halves that are completely separable from each other which are positively coupled and uncoupled with each other by a translational movement along their operating axes of rotation of the two coupling halves, wherein the two coupling halves do not lock with each other in a direction of the operating axes of rotation of the two coupling halves, but the two coupling halves can also perform relative movements to each other in the direction of the operating axes of rotation even under load, and wherein one of the two coupling halves is an integral part of the cartridge and the other of the two coupling halves is an integral part of the applicator main part.   
     
     
         3 . The refillable cosmetic applicator according to  claim 2 , wherein the cosmetic applicator has a second coupling which is an overload coupling designed to slip when the applicator main part is about to transmit a destructive torque to the cartridge, and the second coupling is designed to re-engage automatically after the overload has ended. 
     
     
         4 . The refillable cosmetic applicator according to  claim 3 , wherein the second coupling is an integral part of the applicator main body and is preferably formed entirely within the applicator main body. 
     
     
         5 . The refillable cosmetic applicator according to  claim 3 , wherein the coupling half of the first coupling associated with the applicator main part also forms, in one piece, a coupling half of the second coupling. 
     
     
         6 . The refillable cosmetic applicator according to  claim 3 , wherein one coupling half of the second coupling is a brake disc that rotates relative to a remainder of the applicator main part and rests against an inner brake collar of the applicator main part with a friction fit. 
     
     
         7 . The refillable cosmetic applicator according to  claim 6 , wherein the brake disc forms a conical friction surface which bears against a complementary conical friction surface of the inner brake collar the conical friction surface. 
     
     
         8 . The refillable cosmetic applicator according to  claim 1 , wherein the cartridge has a male or female solid tube section which can be attached to a female or male solid tube section, by a locking bead on an outer circumferential surface of a first tube section and a locking recess on an outer circumferential surface of a second tube section. 
     
     
         9 . A cartridge suitable for installation in the applicator according to  claim 1 . 
     
     
         10 . A refillable cosmetic applicator system comprising the cosmetic applicator according to  claim 1  and at least two of the cartridges. 
     
     
         11 . The refillable cosmetic applicator according to  claim 1 , wherein the cartridge comprises a threaded feed mechanism for the refill.
