Abstract

The invention relates to an assembly including a reservoir that contains a liquid and an applicator equipped with a flexible, elastically deformable pen (3); the pen has the shape of a truncated cone (31), elongated at its end of smaller diameter by a cylindrical portion (32) having the same smaller diameter. The pen may be flocked and may include a cavity (35) through it from one side to the other and opening into the bottom of a capillary groove (34). The invention is usable for applying any liquid makeup product, and in particular for applying eyeliner to the eyelids.

Claims

1. An assembly comprising a reservoir for containing a liquid and an applicator equipped with at least one flexible, elastically deformable pen, wherein the pen has a frustoconical portion having an end of smaller cross section and which is elongated at its end of smaller cross section by a cylindrical portion having this same smaller cross section as said end of said frustoconical portion.

2. The assembly of claim 1, wherein the cross sections of the frustoconical and cylindrical portions of the pen are circular.

3. The assembly of claim 1, wherein the length of the cylindrical portion of the pen is between 5 and 20% of the total length of the frustoconical portion and cylindrical portion of the pen.

4. The assembly of claim 3, wherein the length of the cylindrical end portion of the pen is between 10 and 15% of the total length of the frustoconical portion and cylindrical portion of the pen.

5. The assembly of claim 1, wherein the pen is flocked on the frustoconical portion and the cylindrical portion.

6. The assembly of claim 5, wherein the length of the fibers comprising the flock is between 0.01 and 1.5 mm.

7. The assembly of claim 1, wherein the pen includes at least one transverse cavity and at least one capillary groove, which extends solely over the frustoconical portion, beginning at said cavity and extending in the direction of the end of the pen.

8. The assembly of claim 7, wherein each cavity is a hole pierced diametrically in the frustoconical portion of the pen and opening out on both sides.

9. The assembly of claim 7, wherein each capillary groove is made along a directrix of the frustoconical portion of the pen.

10. The assembly of claim 7, wherein the width and the depth of each capillary groove decreases progressively from the cavity to a vanishing point at the end of the groove adjacent the cylindrical portion of the pen.

11. The assembly of claim 7, wherein the pen includes a single cavity and a single groove.

12. A cosmetic pen comprising:

a frustoconical portion having a first cross-section at a first end and a second cross-section at a second end, the first cross-section having a diameter greater than the second cross-section;

a cylindrical portion, adjacent to the second end of said frustoconical portion, having a cross-section equivalent to the second cross-section of said frustoconical portion;

at least one transverse cavity pierced diametrically through said frustoconical portion near the first end of said frustoconical portion; and

at least one capillary extending from said at least one transverse cavity along a directrix of said frustoconical portion, and ending near the second end of said frustoconical portion.

13. The cosmetic pen of claim 12, wherein said frustoconical portion and said cylindrical portion are flocked.

14. An assembly comprising a reservoir containing a liquid and an applicator equipped with at least one flexible, elastically deformable pen, wherein the pen has a frustoconical portion, elongated at its end of smaller cross section by a cylindrical portion having this same smaller cross section, wherein the length of the cylindrical portion of the pen is between 5 and 20% of the total length of the frustoconical portion and cylindrical portion of the pen.
