  • the product to be applied is a cosmetic product, so that the instrument 1 constitutes in this case a cosmetic instrument.
  • the product to be applied is mascara for the eyelashes, the instrument 1 then constituting a mascara applicator for the eyelashes.
  • the invention is however not limited to the application of a product having a necessarily cosmetic nature, nor the application of a product necessarily having a consistency identical to that of a mascara.
  • the instrument 1 can thus possibly be used to apply any product, whatever its consistency, said product can for example be very fluid, have conversely a very viscous and / or pasty, or be in the form a powder.

  • the instrument 1 comprises a rod 3 extending substantially rectilinear, in an axial direction X-X ', from the gripping member 2 between a proximal end 3A and a distal end 3B.
  • the instrument 1 comprises an application means 4 of the product to be applied to the integuments.
  • the means of application 4 is preferentially designed to collect the product to be applied (for example mascara) and apply it to the integuments (for example the eyelashes).

  • the invention is not limited to a particular structure of the (or) application excrescences 4, said structure being essentially dictated by the consistency of the product to be applied, the nature of the receiving medium (for example: nails), and the desired makeup characteristics.
  • the instrument 1 comprises a core 5 carrying the application means 4, that is to say that said application excrescences 4A are carried by the core 5.
  • the core 5 serves 4A, the latter being thus attached, preferably directly, to the core 5.
  • the core 5 is an integral core, that is to say that it is monoblock, or in other words that it presents a unitary character.
  • This unitary character, monobloc contributes to simplify the manufacture and construction of the instrument 1 according to the invention, which is invaluable for the industrialization of the manufacture of the instrument 1 and the mechanical strength of the latter
  • the core 5 is substantially elongate, that is to say that it has a slender character and extends in this respect mainly in a single direction of space, materialized in this case by the Y-Y 'axis, which corresponds to the longitudinal axis of longitudinal extension of the core 5.
  • the core 5 therefore extends longitudinally along a longitudinal axis of longitudinal extension YY 'which is preferably coincident with the axis X-X'.
  • the core 5 is advantageously made of a flexible, deformable material.
  • the core 5 is made of a plastic or elastomeric material, for example polymer.

  • the use of a molding process for producing the protuberances 4A makes it possible in particular to produce protrusions 4A in contact which is particularly gentle and pleasant for the user.
  • the application protuberances 4A may be distinct and independent of the core 5 and be fixed thereto by any appropriate means, and for example by gluing, flocking, heat sealing, crimping or mechanical assembly, without the fact that the we leave the scope of the invention.
  • the application protuberances 4A abound helically along the core 5, that is to say that they are distributed in a helical layer around the core 5.
  • the application protuberances 4A are distributed in spiral around the middle extension axis YY 'of the core 5.
  • This helical expansion of the application protuberances 4A promotes the loading of the application means 4 into product (mascara) and allows effective combing of the eyelashes, thanks to the multiplicity of orientations of the application protrusions 4A that it induces.
  • Such swirling helix also allows to create, between the propellers, "channels " spiral to accommodate and retain the product to be applied, which again promotes the loading of the application means 4 product.
  • the helical expansion of the protuberances 4A is obtained by twisting the core 5.
  • the core 5 is twisted, that is to say it is twisted, spirally twisted permanent, along its mean axis of longitudinal extension Y-Y '.

  • protuberances 4A extend, from the untwisted core 5, in a first radial direction D1, while other protuberances extend from the core 5 in a second radial direction D2 distinct from the first radial direction D1, while still other growths 4A respectively extend in a third and fourth radial direction D3, D4 distinct.
  • the application protuberances 4A are attached to the core 5 at attachment points which are arranged on the core 5 so that when the core 5 is in the non-twisted state, said attachment points belong to at least three distinct rays relative to the longitudinal axis of longitudinal extension Y-Y '.
  • Such a three-dimensional distribution of the application means 4A on and around the core 5 provides an optimized makeup effect, which combines the advantages of conventional twisted mascara brushes and those associated with molded brushes. It is furthermore found that the instrument 1 according to the invention has an excellent spin-drying behavior, so that it is possible to implement a standard wiper (for example an elastomer) without the risk of seeing the brush be deteriorated under the effect of the mechanical stresses generated by the spinning operation.
  • the protuberances 4A are arranged on the core 5, beforehand at twisting of the latter, according to at least four distinct radial directions D1, D2, D3, D4 about said longitudinal axis of longitudinal extension YY '.
