Application Of Hair-Coloring Compositions

An application device for applying hair-coloring composition, comprising:

• a device body, comprising:
• a first reservoir comprising a first piston;
• said first reservoir configured to receive a first part of a hair-coloring composition;
• a second reservoir comprising a second piston;
• said second reservoir configured to receive a second part of a hair-coloring composition;
• and
• an electric dispensing mechanism associated with said first piston and with said second piston;
• said dispensing mechanism configured to, upon activation, sealingly move said first piston inside said first reservoir and said second piston inside said second reservoir;
• and
• an application cap, comprising:
• a mixing mechanism;
• a containing space in fluid communication with said mixing mechanism;
• and
• a plurality of projecting tines, each in fluid communication with said containing space;
• wherein said application cap is configured for reversible-connection with said device body such that, when said application cap is connected with said device body, said first reservoir and said second reservoir are sealed from the outside except channels of said plurality of projecting tines which are in fluid communication with said first reservoir and said second reservoir, through said mixing mechanism and said containing space;
• and
• wherein said electric dispensing mechanism is configured, when activated, to move said first piston and said second piston towards said plurality of projecting tines thereby mixing said first part of said hair-coloring composition with said second part of said hair-coloring composition to form a mixed hair-coloring composition to be dispensed through said plurality of projecting tines when said containing space is full, and thereby allowing said mixed hair-coloring composition to be uniformly dispensed through said plurality of projecting tines.
