Device for applying an additive to hair roots

Abstract

The invention relates to a device ( 1 ) for applying an additive to hair, comprising a base part ( 2 ), an applicator element ( 3 ) which is connected to an additive reservoir ( 4 ) and has at least one outlet opening ( 5 ) for applying additive to the hair during operation, a hair parting element ( 6 ) for parting the hair during operation, having an end surface ( 7 ) near said outlet opening ( 5 ), and an operating direction ( 8 ) in which the device ( 1 ) is moved during operation. At least a portion ( 9 ) of the hair parting element ( 6 ) adjoining the end surface ( 7 ) has a substantially wedge-shaped cross-section ( 10 ) with a tip ( 11 ) extending practically in the operating direction ( 8 ), the outlet opening ( 5 ) being provided behind the tip ( 11 ), as viewed in the operating direction ( 8 ). The device according to the invention enables effective application of additive to the roots of the hair in a user-friendly manner.

1 . A device ( 1 ) for applying an additive to hair, comprising: 
 a base part ( 2 );    an applicator element ( 3 ) which is connected to an additive reservoir ( 4 ) and has at least one outlet opening ( 5 ) for applying additive to the hair during operation;    a hair parting element ( 6 ) for parting the hair during operation, having an end surface ( 7 ) near said outlet opening ( 5 ); and    an operating direction ( 8 ) in which the device ( 1 ) is moved during operation;    characterized in that at least a portion ( 9 ) of the hair parting element ( 6 ) adjoining the end surface ( 7 ) has a substantially wedge-shaped cross-section ( 10 ) with a tip ( 11 ) extending practically in the operating direction ( 8 ), the outlet opening ( 5 ) being provided behind the tip ( 11 ), as viewed in the operating direction ( 8 ).    
   
   
       2 . A device as claimed in  claim 1 , characterized in that said portion ( 9 ) of the hair parting element ( 6 ) adjoining the end surface ( 7 ) extends at least as far as the outlet opening ( 5 ), as viewed in the operating direction ( 8 ).  
   
   
       3 . A device as claimed in  claim 1 , characterized in that the portion ( 9 ) of the hair parting element ( 6 ) adjoining the end surface ( 7 ) has walls ( 12 ) enclosing a hollow space ( 13 ) between the tip ( 11 ) and the outlet opening ( 5 ).  
   
   
       4 . A device as claimed in  claim 1 , characterized in that a distribution member ( 18 ) is provided behind the portion ( 9 ) of the hair parting element ( 6 ) adjoining the end surface ( 7 ), as viewed in the operating direction ( 8 ).  
   
   
       5 . A device as claimed in  claim 4 , characterized in that said distribution member ( 18 ) comprises a plurality of pins ( 28 ).  
   
   
       6 . A device as claimed in  claim 1 , characterized in that a plurality of applicator elements ( 3 ) and a plurality of hair parting elements ( 6 ) are provided in a predetermined arrangement on the base part ( 2 ).  
   
   
       7 . A device as claimed in  claim 1 , characterized in that the end surface ( 7 ) comprises a curved surface.  
   
   
       8 . An electrical apparatus for the colouring of hair ( 31 ), comprising electrical pumping means ( 32 ), power supply means ( 33 ), and a device ( 1 ) for applying a colouring additive to hair, which device comprises a base part ( 2 ), an applicator element ( 3 ) which is connected to an additive reservoir ( 4 ) and has at least one outlet opening ( 5 ) for applying additive to the hair during operation, a hair parting element ( 6 ) for parting the hair during operation, having a end surface ( 7 ) near said outlet opening ( 5 ), and an operating direction ( 8 ) in which the device ( 1 ) is moved during operation, characterized in that said device ( 1 ) for applying a colouring additive to hair is a device as claimed in any of the preceding claims.
