Another subject of the invention is an applicator for applying a makeup or care cosmetic to a human keratinous material having a felt applicator tip, the applicator tip defining an application surface of the cosmetic, extending along a longitudinal axis, And at least three longitudinal grooves each extending along an axis included in the plane including the longitudinal axis of the applicator tip.

The presence of the oblique grooves provides flexibility to the applicator tip and provides application flexibility. And, the grooves make it possible to create reserves of cosmetics on the application surface.

The longitudinal grooves promote the flow of the cosmetic in the direction of its distal end to the applicator.

The longitudinal or angled grooves or grooves are each advantageously extended along the entire axis that is not perpendicular to the longitudinal axis of the applicator tip.

The longitudinal or oblique grooves or grooves are preferably not through-grooves over their entire length.

The longitudinal or oblique grooves or grooves may optionally extend to the distal end of the applicator tip.

The longitudinal or oblique grooves or grooves may extend over only a portion of the application surface or over the entire length.

Several longitudinal or angled grooves may be positioned about the longitudinal axis of the applicator tip.

The longitudinal grooves may be evenly distributed about the longitudinal axis of the applicator tip. This makes it possible to uniformly distribute the cosmetic on the application surface.

If the applicator tip has a mounting end piece, the oblique or longitudinal grooves or grooves may extend thereon.

The oblique grooves or grooves may each extend over less than one revolution about the longitudinal axis of the applicator tip.

In one variant, the oblique grooves or grooves form one or more turns about the longitudinal axis of the applicator tip, in particular one or more annular grooves.

The oblique grooves cut certain fibers and thus modify the diffusion of the cosmetic by capillary action within the applicator tip. In particular, by adjusting the arrangement of the grooves or grooves, it is possible to influence the distribution of cosmetics on the application surface. In particular, it can promote diffusion into the tip in fibers that are not interrupted by grooves or grooves, and can slow the diffusion of cosmetics on the surface of the fibers that are interrupted by grooves or grooves. This may increase precision by allowing the tip to track a thin smudge-free line if desired.

The applicator tip is preferably produced by cutting a one-piece cylindrical blank, particularly with the aid of an orientable cutting tool which is movable in all spatial directions.

The applicator tip is preferably impregnated with a cosmetic product to be applied, in particular an eyeliner. This may allow the cosmetic to be easily diffused by capillary action. The fibers enable the cosmetic to be transported along the applicator tip.

The longitudinal or oblique grooves or grooves may be produced by machining of the blank, by deformation, or by heating.

Except for grooves or grooves, the applicator tip may not have any perforations or recesses in its surface used for application. Thus, the applicator tip may not have any outwardly concave edges at its distal end.

The applicator tip may have a narrowed section between the applicator portion defining the application surface and the end piece for mounting the applicator tip to the body of the applicator pen or the stem of the applicator.
