Abstract

A device for a timepiece, comprising a support, an inertial regulating member mounted so as to rotate relative to the support by an elastic suspension connecting said regulating member to the support. The regulating member comprises a number n of rigid portions interconnected in pairs by n elastic coupling links. The elastic suspension comprises n elastic suspension links respectively connecting each rigid portion to the support.

First claim

The invention claimed is:

1. An applicator device for applying a cosmetic product onto keratinous materials comprising:
a rod, the rod having a first and a second end, the rod extending in a longitudinal direction of the rod between the first and second ends of the rod,
a gripping member, the gripping member being located at the first end of the rod, the rod being rigid,
an applicator element near the second end of the rod, the applicator element defining a longitudinal direction of the applicator element at rest, the applicator element having an application portion suitable for applying the cosmetic product,
a flexible, elastically deformable core, the core connecting the applicator element to the rod,

wherein:
the core comprises a free portion extending freely between the rod and the application portion of the applicator element, the free portion of the core having a length of at least 2 mm, the core allowing maximum bending of the applicator element relative to the rod such that a maximum bending angle between the longitudinal direction of the bent applicator element and the longitudinal direction of the applicator element at rest is at least 1°, and wherein
the rod has a housing extending in the longitudinal direction of the rod between a bottom of the housing and an outlet of the housing at the second end of the rod, the application portion of the applicatior element protruding from the housing, the core extending into the housing with transverse clearance, wherein the maximum bending angle between the longitudinal direction of the bent applicator element and the longitudinal direction of the applicator element at rest is defined by abutment of one of the applicatior elment or the core against a side wall of the housing.

2. The applicator device according to claim 1 , wherein the maximum bending angle is at most 30°.

3. The applicator device according to claim 1 , wherein the core has a cross-section, the cross-section of the core has a diameter, the rod has a cross-section, the cross-section of the rod has a diameter, the diameter of the cross-section of the core being less than or equal to the diameter of the cross-section of the rod.

4. The applicator device according to claim 1 , wherein the core is fixed in a hole that opens at the bottom of the housing.

5. The applicator device according to claim 1 , wherein the housing is tubular, the housing having a length measured between the bottom of the housing and the outlet of the housing, and a diameter measured in a plane transverse to the length.

6. The applicator device according to claim 1 , wherein the housing is frustoconical, the housing having a length and a maximum diameter, measured in a plane transverse to the length, at the end of the rod.

7. The applicator device according to claim 1 , wherein the core comprises a twisted wire, the application portion being formed by tufts of bristles gripped by the twisted wire.

8. The applicator device according to claim 7 , wherein the core extends in a longitudinal direction of the applicator element at rest and the tufts of bristles extend transversely to the longitudinal direction of the applicator element at rest.

9. The applicator device according to claim 7 , wherein the tufts of bristles have a longitudinal position on the core and a length measured transversely to the longitudinal direction of the applicator element, the length of the tufts of bristles being a function of the longitudinal position on the core.

10. The applicator device according to claim 7 , wherein the core has a short-bristled portion, said short-bristled portion being distinct from the application portion of the applicator element.

11. The applicator device according to claim 7 , wherein the wire has a diameter greater than or equal to 0.3 mm and/or less than or equal to 0.7 mm.

12. The applicator device according to claim 1 , wherein the applicator element has an application portion provided with spikes and/or flocked.

13. The applicator device according to claim 12 , wherein the applicator element has a base portion contiguous with the application portion.

14. The applicator device according to claim 12 , wherein the applicator element is of flexible material.

15. The applicator device according to claim 12 , wherein the core is one piece with the rod.

16. The applicator device according to claim 12 , wherein the core is one piece with the applicator element.

17. The applicator device according to claim 12 , wherein the core is distinct from the rod and from the applicator element.

18. The applicator device according to claim 1 , wherein the core has a diameter greater than 0.3 mm.

19. The applicator device according to claim 1 , wherein the core has a diameter less than 2.5 mm.

20. A device for packaging and application of a cosmetic product to be applied to keratinous materials, comprising the_applicator device according to claim 1 , and a container for containing the product to be applied, the applicator device being suitable for fixing to the container such that the applicator element is received inside the container, in contact with the cosmetic product.

21. The device for packaging and application according to claim 20 , wherein the container has an opening and the gripping member is suitable to be fixed on the container in order to close the opening of the container.
