Abstract

The subject of the invention is a cosmetic applicator, in particular for the eyelashes or the contour of the eyes, comprising:
a gripping member, an applicator element, a stem connecting the gripping member and the applicator element, the axis of the stem extending in all three dimensions of space.

First claim

The invention claimed is:

1. A cosmetic applicator comprising:
a gripping member comprising an internal thread and having a longitudinal axis;
an applicator element having a longitudinal axis; and
a stem extending from the gripping member to the applicator element and formed of a polymeric material, the stem comprising:
a first rectilinear portion that extends from the gripping member;
a first curve extending from the first rectilinear portion and having a first radius of curvature and a first axis of curvature; and
a second curve extending from the first curve toward the applicator element, the second curve having a second radius of curvature and a second axis of curvature, wherein,
an axis of the stem that connects all centers of mass of cross sections of the stem cannot be contained in a single plane,
the first radius of curvature is greater than the second radius of curvature, and
the first and second curves are configured such that an angle formed between the longitudinal axis of the gripping member and the longitudinal axis of the applicator element-ranges from about 25° to about 90°.

2. The cosmetic applicator of claim 1 , wherein the angle between the longitudinal axis of the gripping member and the longitudinal axis of the applicator element is about 90°.

3. The cosmetic applicator of claim 1 , wherein:
the first curve is concave toward a first side of the stem and the second curve is concave toward an opposite second side of the stem; and
the first axis of curvature is not parallel to the second axis of curvature.

4. The cosmetic applicator of claim 1 , wherein the longitudinal axis of the gripping member and the longitudinal axis of the applicator are both rectilinear.

5. The cosmetic applicator of claim 1 , wherein the stem is elastically deformable.

6. A device for packaging and applying a cosmetic product, comprising:
a container containing a cosmetic product; and
an applicator comprising:
a gripping member comprising an internal thread and having a longitudinal axis;
an applicator element having a longitudinal axis; and
a stem extending from the gripping member to the applicator element and formed of a polymeric material,

wherein the stem comprises:
a first linear portion that extends from the gripping member;
a first curve extending from the first linear portion and having a first radius of curvature and a first axis of curvature; and
a second curve extending from the first curve toward the applicator element, the second curve having a second radius of curvature and a second axis of curvature, wherein,
an axis of the stem that connects all centers of mass of cross sections of the stem cannot be contained in a single plane,
the first radius of curvature is greater than the second radius of curvature, and
the first and second curves are configured such that an angle formed between the longitudinal axis of the gripping member and the longitudinal axis of the applicator element ranges from about 25° to about 90°.

7. A cosmetic process for making up the eyelashes or the contour of the eye lids, the process comprising:
providing the cosmetic applicator of claim 1 ,
contacting the eyelashes and/or eyelids with the applicator element of the applicator.

8. The cosmetic process of claim 7 , wherein the outer third of the eyelashes and/or eyelid, the central third of the eyelashes and/or eyelid, and the inner third of the eyelashes and/or eyelid are made up successively.

9. The cosmetic process of claim 8 wherein the step of contacting the eyelashes comprises rotating the gripping member;
wherein a direction of rotation of the gripping member is always the same for curling, lifting and extending the eyelashes.
