Definitions

• the invention relates to the field of applicators for applying a fluid or pasty product on keratin fibers such as eyelashes or eyebrows.
• the applicators of the invention allow to apply a cosmetic product, makeup or care on the hair, eyelashes or eyebrows.
• These applicators essentially comprise two elements: an elongated core on which is disposed at least one row of teeth or pins.
• the document FR 2 850 549 discloses an applicator brush for a product on keratinous fibers, comprising a bristle-supporting core of which at least a portion extend in a curved manner. Also known from FR 2 902 984 an applicator having a core and at least two rows of teeth each oriented differently vis-à-vis an outer face of the core. This type of applicator aims to improve the application of a product in particular in terms of penetration of the teeth between the eyelashes or other, smoothing the product on the eyelashes and separating them.
• EP1 593 320 which describes a mascara applicator consisting of several moving parts relative to each other and in particular a support member in which can slide axially an adjusting element.
• This mobility makes it possible to act on the distance between the two ends of a deformable portion of the support element. It is the user himself who modifies the distance between the two ends and therefore the external volume of the applicator which comprises radially deformable parts under the action of the adjustment element. It is considered that the user can thus act on the amount of product that the applicator loads.
• This applicator is different, complex to realize since formed of several pieces. It requires adjustment by the user before use.
• the geometry disclosed includes a continuous circumference about the longitudinal axis which is not the subject of the present patent application.
• this prior art does not reveal at least one flexible rod blocking with the longitudinal core and embedded in at least two points on the longitudinal core.
• patent application FR 2 895 218 A1 discloses an applicator design similar to that described in EP1 593 320; indeed this applicator is complex, consisting of several distinct elements including a central actuating rod and several so-called axial elements secured at each of their ends by rings. The user can stretch more or less the axial elements, for example by acting on a wheel that cooperates with the rings. Furthermore, the purpose of the applicator described in this document is to modify the interior space so as to act on the amount of cosmetic product retained in the applicator.
• patent application FR 2 506 581 A1 shows a make-up brush of the same type as those disclosed above, consisting of several movable parts relative to each other.
• the invention aims to overcome the disadvantages of the state of the art and in particular to provide an applicator device for liquid or pasty products in the field of cosmetics or hair care, which allows to maintain an optimal product load after crossing a small diameter wiper.

• at least one rod is embedded at each of its ends substantially merged with each end of said elongated core.
• At least one rod has at least one concave or convex curvature vis-à-vis the longitudinal axis XX.
• a rod may have a single curvature, convex or concave along the entire length of the soul, but other possibilities may be envisaged without departing from the scope of the invention, such as for example several curvatures.
• said at least one rod comprises at least a first and a second straight portions arranged such that one of their ends coincides with the first or the second end of the longitudinal core. and in that their other extremity coincides with it.
• said at least one rod has a non-smooth outer surface (with depressions). It is possible here to imagine a bumpy outer surface, provided with holes and / or protuberances which may have various functionalities in themselves.
• the device may comprise pins which may be connected to at least one of said rods, and / or which may be connected to the outer wall of the core.
• said pins are oriented substantially radially vis-à-vis the longitudinal axis XX.
• said at least one rod has a cross section of value less than the cross section of the core.
