In an applicator for mascara, hair colorants or similar cosmetic products including a main body of a relatively hard material, such as metal or hard plastic, the main body being connectable to a rod and having a plurality of circumferential grooves, provision is made, in order to improve the combing action and transfer properties, for the grooves to extend parallel to each other and substantially perpendicular to the longitudinal axis.
1. A mascara applicator comprising
a main body of metal for applying mascara to an eyelash, said main body comprising a first frusto-conical end section, a cylindrical middle section, and a second frusto-conical end section, said first frusto-conical end section having a recess defined therein, said recess extending only part-way through the main body,
said main body being connectable to a rod and having a plurality of circumferential grooves defined therein, said rod being inserted into said recess, said plurality of grooves extending entirely over said first frusto-conical end section and said cylindrical middle section, and only partway over said second frusto-conical end section, so as to leave a portion of said second frusto-conical end section without any grooves,
each groove of said plurality of grooves lying in a plane that extends parallel to each other and substantially perpendicular to a longitudinal axis of the main body,
wherein each of the grooves is V or U shaped in cross section and has two planar smooth side surfaces;
wherein the depth of the grooves is configured to transfer mascara to an eyelash and being 0.4 mm to 2.1 mm;
wherein bottom of at least one of the grooves and a ridge between two adjacent grooves is formed rounded; and
wherein said plurality of grooves comprises 5 to 85 grooves.
2. An applicator according to claim 1 , wherein the main body is substantially cylindrical.
3. An applicator according to claim 1 , wherein the spacing between two adjacent grooves is 0.2 to 1.0 mm.
4. An applicator according to claim 3 , wherein the spacing between two adjacent grooves is 0.64 mm.
5. An applicator according to claim 1 , wherein the applicator is composed of a chromium-nickel alloy.
6. An applicator according to claim 1 , wherein a curvature radius is between 0.05 and 0.3 mm.
7. An applicator according to claim 1 , wherein the longitudinal bore is filled with a lighter-weight material.
8. An applicator according to claim 7 , wherein the longitudinal bore is filled with a plastic material.
9. An applicator, especially according to claim 1 , wherein the main body has a connecting section for connection to the rod, said connecting section being pentagonal in cross section at least in sections.
10. An applicator according to claim 1 , wherein the depth of the grooves is approximately 0.8 mm.
