Applicator for applying an oxidative hair dye
View Patent ↗The applicator ( 1 ) for applying an oxidative hair dye to human hair, especially to hair strands, has two compartments or chambers ( 2,3 ) for a liquid oxidation dye and an oxidizing agent respectively. Both the oxidation dye and the oxidizing agent are dispensed together at a product-dispensing spot or area of the applicator. The compartments ( 2,3 ) are provided with respective product-dispensing openings ( 5,6 ), which open next to each other, so that a reactive dyeing mixture is provided only outside of the applicator, especially on human hair. For improve applicability liquid-permeable inserts ( 7,8 ) made of spongy material, bristles or fabric, especially felt, are provided in the product-dispensing openings ( 5,6 ), preferably protruding from them somewhat.

wherein said two compartments ( 2 , 3 ) are provided with respective product-dispensing openings ( 5 , 6 ), which are arranged so as to open next to each other into the product-dispensing area or spot ( 4 );
wherein corresponding liquid-permeable inserts ( 7 , 8 ) are inserted in said two compartments ( 2 , 3 ) through said respective product-dispensing openings ( 5 , 6 ) so as to protrude beyond said product-dispensing opening, said corresponding liquid-permeable inserts ( 7 , 8 ) comprising a spongy material, bristles, or a fabric that is permeable for the oxidizing agent and the oxidative hair dye composition; and
wherein said compartments are provided with means for preventing drying out of said oxidizing agent and said oxidative hair dye composition.
2. The applicator as defined in claim 1 , wherein said liquid-permeable inserts ( 7 , 8 ) are made of felt.
3. The applicator as defined in claim 1 , wherein said liquid-permeable inserts ( 7 , 8 ) protrude beyond said product-dispensing openings ( 5 , 6 ) by about 1 to 10 mm.
4. The applicator as defined in claim 1 , wherein one ( 5 ) of said product-dispensing openings is arranged centrally and provided with a circular cross-section and another ( 8 ) of said product-dispensing openings concentrically surrounds said one ( 5 ) of said product-dispensing openings and has an annular cross-section.
5. The applicator as defined in claim 1 , wherein said first compartment ( 2 ) is cylindrical and said second compartment ( 3 ) surrounds said first compartment and has an annular cross-section.
6. The applicator as defined in claim 1 , wherein one of said two compartments ( 2 , 3 ) exchangeable.
7. The applicator as defined in claim 6 , wherein said means for preventing drying out of said oxidizing agent and said oxidative hair dye composition comprises corresponding covering foils ( 18 ) for closing said respective product-dispensing openings ( 5 , 6 ) and wherein the covering foils ( 18 ) are connected in a liquid-tight manner with walls ( 14 , 15 ) of said two compartments ( 2 , 3 ).
8. The applicator as defined in claim 7 , wherein said covering foils ( 18 ) comprise strips or tab ( 19 ) for easy removal of the covering foils.
9. The applicator as defined in claim 1 , wherein said first compartment ( 2 ) is insertable together with one ( 7 ) of said inserts into a remaining portion of the applicator or into said second compartment ( 3 ).
10. The applicator as defined in claim 9 , wherein said first compartment ( 2 ) is insertable through an opening ( 11 ) in a base ( 12 ) of said remaining portion and is provided with a stop ( 13 ) for keeping said first compartment ( 2 ) at a desired position in relation to said second compartment ( 3 ).
11. The applicator as defined in claim 1 , wherein said means for preventing drying out of said oxidizing agent and said oxidative hair dye composition comprises a covering foil ( 18 ) for covering the product-dispensing opening ( 5 , 6 ) and wherein the covering foil ( 18 ) is connected in a liquid-tight manner with walls ( 14 , 15 ) of said two compartments ( 2 , 3 ).
12. The applicator as defined in claim 11 , wherein said covering foil ( 18 ) comprises a strip or tab ( 19 ) for easy removal of the covering foil.
13. The applicator as defined in claim 1 , wherein said means for preventing drying out of said oxidizing agent and said oxidative hair dye composition comprises a cap ( 10 ) for closing said product-dispensing openings ( 5 , 6 ).
14. The applicator as defined in claim 1 , wherein said oxidizing agent comprises a peroxide solution.
15. An applicator for applying an oxidative hair dyeing mixture to human hair, said applicator ( 1 ) comprising
a cylindrical compartment ( 2 ) containing an oxidative hair dye composition; and
an annular compartment ( 3 ) surrounding the cylindrical compartment, said annular compartment having an annular cross-section and containing an oxidizing agent;
wherein said cylindrical compartment is insertable through an opening ( 11 ) provided in a base ( 12 ) of a remaining portion of the applicator, said remaining portion comprising said annular compartment ( 3 ), and said cylindrical compartment is provided with a stop ( 13 ) so that said cylindrical compartment cannot travel beyond a predetermined final position in said annular compartment ( 3 );
wherein said compartments ( 2 , 3 ) are provided with respective product-dispensing openings ( 5 , 6 ), which are arranged so as to open next to each other into a product-dispensing space or area ( 4 ), and with corresponding covering foils ( 18 ) connected in a liquid-tight manner with walls ( 14 , 15 ) of said compartments ( 2 , 3 ) in order to close said product-dispensing openings ( 5 , 6 ) and thus prevent drying out of the oxidizing agent and hair dye composition; and
wherein said cylindrical compartment is replaceable in operation to change said oxidative hair dye composition.
16. The applicator as defined in claim 15 , further comprising corresponding liquid-permeable inserts ( 7 , 8 ) inserted into said compartments ( 2 , 3 ) through said respective product-dispensing openings ( 5 , 0 ) so as to protrude from the product-dispensing openings ( 5 , 6 ) and wherein said inserts ( 7 , 8 ) are made of a spongy material, bristles, or a fabric that is permeable for the oxidizing agent and the oxidative hair dye composition.
17. The applicator as defined in claim 16 , wherein said liquid-permeable inserts ( 7 , 8 ) protrude into the product-dispensing space or area ( 4 ) and beyond said product-dispensing openings ( 5 , 8 ) by about 1 to 10 mm, so that, when said covering foils are removed, said oxidizing agent and said oxidative hair dye composition pass through said inserts and are mixed in said product-dispensing space or area ( 4 ) to form the oxidative hair dyeing mixture.
18. The applicator as defined in claim 15 , wherein said covering foil ( 18 ) comprises a strip or tab ( 19 ) for easy removal of the covering foil.
