Hair treatment fluid application device

Abstract

A hair treatment fluid application device includes a flexible container for containing a hair treatment fluid, an applicator body having outlet orifices for applying the hair treatment fluid to hair, the flexible container having a passage opening for allowing egress of the hair treatment fluid from the flexible container to the applicator body, a housing for accommodating the flexible container, a piston for exerting pressure on the flexible container for forcing the hair treatment fluid from the flexible container through the passage opening to the applicator body by deforming the flexible container, and a driver for driving the piston.

1 . A hair treatment fluid application device comprising:
 an applicator body having outlet orifices for applying said hair treatment fluid to hair;   a flexible container for containing said hair treatment fluid, said flexible container having a passage opening for allowing egress of said hair treatment fluid from said flexible container to said applicator body;   a housing for accommodating said flexible container;   pressure means for exerting pressure on said flexible container for forcing said hair treatment fluid from said flexible container through said passage opening to said applicator body by deforming said flexible container,   wherein said pressure means comprise moving means for moving a pressure body in a direction of movement against said flexible container, and   wherein said pressure body is a piston; and   driving means for driving said pressure means.   
   
   
       2 . The device as claimed in  claim 1 , wherein said pressure means are located within said housing. 
   
   
       3 . The device as claimed in  claim 1 , wherein said passage opening comprises a one-way valve. 
   
   
       4 . The device as claimed in  claim 1 , wherein said housing is provided with a one-way valve member for hair treatment fluid which has issued through said passage opening to the exterior. 
   
   
       5 - 8 . (canceled) 
   
   
       9 . The device as claimed in  claim 1 , wherein said housing acts as a cylinder for said piston. 
   
   
       10 - 11 . (canceled) 
   
   
       12 . The device as claimed in  claim 1 , wherein reset means are provided for returning said piston to an initial position. 
   
   
       13 . A hair treatment fluid application device comprising:
 an applicator body having outlet orifices configured to apply hair treatment fluid to hair;   a flexible container configured to contain the hair treatment fluid, the flexible container having a passage opening configured to allow an egress of the hair treatment fluid from the flexible container to the applicator body;   a housing configured to accommodate the flexible container;   a motor; and   a piston operably coupled to the motor, wherein the motor is configured to exert pressure on the flexible container for forcing the hair treatment fluid from the flexible container through the passage opening to the applicator body by moving the piston in a direction of movement against the flexible container and thereby, deforming the flexible container.   
   
   
       14 . The device as claimed in  claim 13 , wherein the motor is located within the housing. 
   
   
       15 . The device as claimed in  claim 13 , wherein the passage opening comprises a one-way valve. 
   
   
       16 . The device as claimed in  claim 13 , wherein the housing comprises a one-way valve configured to receive hair treatment fluid which has issued through the passage opening. 
   
   
       17 . The device as claimed in  claim 13 , wherein an interior portion of the housing is configured to act as a cylinder for the piston. 
   
   
       18 . The device as claimed in  claim 13 , comprising a reset switch configured to return the piston to an initial position.
