  • the present invention relates to an applicator for applying a cosmetic, makeup or care, product to the eyelashes and/or eyebrows, for example mascara.
  • the invention also relates to devices having a container which contains the product to be applied and is provided with a wiping member, and the applicator.
  • Applicators having arms that carry application elements and form one or more openings between one another are known from the applications EP 1 726 234 and EP 1 169 941.

  • the applications FR 2 962 015 and FR 2 943 226 furthermore describe applicators having a twisted core.
  • the application FR 2 936 691 describes an applicator having a twisted kernel that carries application elements which are present prior to the twisting of the kernel.
  • the application FR 2 958 129 discloses an applicator having a drive system for bringing a core that carries moulded application elements from a rest configuration, in which the core is not twisted, into a configuration in which it is twisted.
  • This applicator is relatively complex to produce and it is fairly large on account of the presence of the drive system.
  • a subject of the invention is an applicator for applying a cosmetic, makeup or care, product to the eyelashes and/or eyebrows, having an applicator member having:
  • the distance between the bow and the longitudinal axis of the core measured perpendicularly to the core, being variable along the core and passing through a maximum away from the ends for attaching the bow to the core.
  • the invention makes it possible to obtain, on the applicator member, between the core and the bow, at least one zone that forms a reservoir and which acquires a surplus of product after wiping.
  • Said surplus of product allows the eyelashes and/or eyebrows to be loaded with a large and satisfactory amount of product from the first application. Said eyelashes and/or eyebrows can then be easily separated using the application elements carried by the bow.
  • a further subject of the invention is a method for manufacturing an applicator according to the invention. This method may comprise steps in which:
  • a rotation is imposed on one of the portions with respect to the other such that the bow extends in a twist around a longitudinal axis of the applicator.
  • This manufacturing method makes it possible to alleviate the tricky problem of demoulding twisted components. Specifically, the two portions and the bow are first of all moulded without a twist and the two portions are then rotated with respect to one another.
  • the bow can thus take up a rest configuration, in which it is rectilinear and not twisted, and a twisted configuration.
  • the bow is initially contained in one and the same diametric plane as the axis of the two portions that it connects following moulding.

  • the longitudinal axis of the core is rectilinear.
  • application element denotes an individualizable projecting element intended to come into engagement with the eyelashes and/or eyebrows.

  • the applicator is advantageously removed from the container in the opposite direction to the direction of the twist, thereby allowing it to be more rigid with respect to the product and allowing more effective mixing of the latter before it is picked up.
  • the distance between the bow and the longitudinal axis of the core may increase, from the distal end for attaching the bow to the core, until it reaches a maximum located approximately halfway between the ends for attaching the bow to the core, and then decrease again towards the proximal end for attaching the bow to the core.
