Applicator for hair dyes

Abstract

The invention relates to an applicator comprising an applicator device for applying a product fed from a separate supply to the application zone onto a strand of hair or fiber, and a strand gripper that can be moved back and forth between a closed position and a released position, which at least serves for guiding a strand in the region of the application zone by means of a guiding surface provided for this purpose, wherein the applicator device comprises an application body mounted on the applicator device such that it rotates when a hair or fiber strand is pulled through the intermediate space formed between it and the guiding surface of the strand gripper.

1 . Applicator, comprising:
 an applicator device for applying a product fed from a separate supply to an application zone on a strand of hair or fiber;   a strand gripper that can be moved back and forth between a closed position and a released position, which at least serves for guiding a strand in a region of the application zone using a guiding surface provided thereon for this purpose; and   an application body mounted on the applicator device such that the application body rotates when a hair or fiber strand is pulled through the intermediate space formed between the application body and the guiding surface of the strand gripper.   
     
     
         2 . The applicator according to  claim 1 , wherein the guiding surface, in the closed position of the gripper, retains the strand in contact with the application body. 
     
     
         3 . The applicator according to  claim 2 , wherein the application body, in the region in which it can be brought into contact with the strand as intended, has a ball-like or drum-like external outline. 
     
     
         4 . The applicator according to  claim 2 , wherein the application body, in the region of a surface that can be brought into contact with the strand as intended, consists of a soft elastic material or an elastomeric material. 
     
     
         5 . The applicator according to  claim 2 , wherein the application body, in the region of a surface that can be brought into contact with the strand as intended, consists of a material and/or has a surface profile which, taking into account the product that is to be applied as intended with the applicator, has a high friction with regard to the strands to be treated as intended with the applicator even in a wetted state, such that the applicator rolls on the respectively treated strand grip substantially uniformly while the latter is pulled through the applicator. 
     
     
         6 . The applicator according to  claim 1 , wherein the application body has a covering of radially outwardly protruding bristles or bristle discs. 
     
     
         7 . The applicator according to  claim 6 , wherein the bristles or bristle discs are configured to be integral with the application body or at least a surface sealing the application body towards the outside. 
     
     
         8 . The applicator according to  claim 1 , wherein the applicator device has an interior channel in the area of whose mouth an application body, preferably in a bristle-like form, is rotatably retained, wherein the side of the application body facing away from the mouth is charged with the product fed via the channel and applies the product during its rotation. 
     
     
         9 . The applicator according to  claim 1 , wherein the applicator device has an interior channel, via which the product to be applied is fed from a supply, wherein a narrowed portion of the channel having a dosing effect is provided in a region of a mouth of the channel. 
     
     
         10 . The applicator according to  claim 9 , wherein the narrowed portion with a dosing effect is disposed so far upstream of the mouth that a chamber is formed, between the mouth and the narrowed portion, with a cross section that is wider compared with the narrowed portion, into which chamber a part of the application body dips. 
     
     
         11 . The applicator according to  claim 8 , wherein the application body and the mouth are adapted to each other such that the application body substantially seals the mouth such that, between the application body and the mouth, only a defined gap remains free, through which the rotating application body carries the product to be applied outside. 
     
     
         12 . The applicator according to  claim 1 , wherein the applicator device has a mouth via which the product fed from a supply escapes, wherein the applicator device, in the region of its mouth, has guiding surfaces which prevent a strand pulled in its longitudinal direction over the mouth from slipping into an area outside of the mouth. 
     
     
         13 . The applicator according to  claim 1 , wherein the applicator device has a mouth via which the product fed from a supply escapes, wherein the applicator device, in the region of the mouth, has supporting surfaces against which the strand gripper can support itself under the influence of the forces that a strand pulled in its longitudinal direction over the mouth exerts on it. 
     
     
         14 . The applicator according to  claim 13 , wherein the application body comprises an axis which is preferably integrally molded onto it. 
     
     
         15 . The applicator according to  claim 14 , wherein the axis of the application body is latched on both sides into a seat on the applicator which retains it substantially stationary but rotatably. 
     
     
         16 . The applicator according to  claim 15 , wherein each of the two seats is formed between two merlon-like members.
