Claims
1. Applicator (2) for applying a cosmetic product to the eyelashes and/or eyebrows, comprising a monobloc applicator member (8) made of at least a non thermoplastic material, the applicator member (8) comprising:
- a core (10) extending along a longitudinal axis (X), the core (10) comprising at least one helical groove (16, 17) extending along the longitudinal axis (X) around the latter and forming more than one turn around the longitudinal axis of the core (X),
- at least one row of applicator elements (18; 18a, 18b;18c, 18d) extending from the core, helically around the longitudinal axis of the core (X), along the helical groove (16, 17), in particular parallel to the latter.
2. Applicator according to Claim 1, wherein the applicator member (8) is obtained by additive manufacturing, in particular on the basis of a preestablished digital model by solidification of a raw material, slice by slice, from one end of the applicator member (8) to the other.
3. Applicator according to Claim 1 or 2, wherein the row of applicator elements forms a plurality of turns around the longitudinal axis of the core, in particular more than 3 turns, better still more than 5 turns, even better still between 6 turns and 15 turns, even better still between 6 turns and 12 turns around the core.
4. Applicator according to any one of the preceding claims, wherein the core (10) comprises at least two helical grooves (16, 17) extending around the longitudinal axis of the core (X), in opposite directions and with the same pitch, the two grooves (16, 17) preferably being parallel to one another.
5. Applicator according to Claim 4, wherein the applicator elements (18; 18a, 18b; 18c, 18d) extend in at least two helical rows around the longitudinal axis of the core, the rows being parallel to the grooves (16, 17).
6. Applicator according to any one of the preceding claims, wherein the applicator elements (18; 18a, 18b; 18c, 18d) extend in one or more helical rows forming spirals around the longitudinal axis of the core (X), and applicator elements (18; 18a, 18b; 18c, 18d) extending from adjacent spirals along the longitudinal axis of the core (X) are not superposed at their bases, when the applicator member (8) is seen end-on.
7. Applicator according to any one of the preceding claims, wherein the applicator member (18; 18a, 18b; 18c, 18d) comprises two types of applicator element (18a, 18b), the applicator member (8) comprising first applicator elements (18b) in the form of spikes and second applicator elements (18a) taking a different form to the first applicator elements, in particular in the form of teeth, loops and/or comprising one or more surface reliefs, for example one or more protuberances and/or an enlarged head.
8. Applicator according to Claim 7, wherein the or each row of applicator elements (18; 18a, 18b) comprises alternating first applicator elements (18b) and second applicator elements (18a).
9. Applicator according to Claim 7 or 8, wherein the second applicator elements (18a) extend in a plane transverse to the longitudinal axis of the core (X) being inclined at their base relative to a radius starting from the core, in particular making an angle of between 0 and 90°, better still between 5 and 30°, even better still between 10 and 20°.
10. Applicator according to any one of Claims 7 to 9, wherein the second applicator elements (18a) are perpendicular at their base to the surface of the core (10) from which they extend.
11. Applicator according to any one of Claims 7 to 10, wherein the first applicator elements (18b) are inclined at least partially towards the same longitudinal end (13; 11) of the applicator member (8).
12. Applicator according to any one of Claims 7 to 11, wherein the first applicator elements (18b) are inclined relative to the radial axis (R) of the core at their base by an angle a of between 0 and 90°, better still between 5 and 30°, even better still between 10 and 20°.
13. Applicator according to any one of Claims 7 to 12, wherein the distal ends of the second applicator elements (18a) define the envelope surface (S) of the applicator member (8).
14. Applicator according to any one of Claims 1 to 6, wherein the applicator member (8) comprises only a single type of applicator elements (18; 18c, 18d) of the same shape, in particular the shape of teeth, of a loop and/or comprising one or more surface reliefs, for example one or more protuberances and/or an enlarged head.
15. Device for packaging and applying a product to the eyelashes and/or eyebrows, comprising an applicator according to any one of the preceding claims and a container containing the product.
16. Method for producing an applicator according to any one of Claims 1 to 14, wherein a blank of the applicator member or the applicator member itself is produced in successive layers with relative movement of the part already built in the direction away from the build zone.
17. Method for making up the eyelashes and/or eyebrows using an applicator according to any one of Claims 1 to 14, wherein the product is applied by bringing the applicator into contact with the eyelashes and/or eyebrows.
