Definitions

  • the present invention relates to an applicator for applying a product to the hair, notably a hair dyeing product for easy highlights and streaking strands or portions of hair.
  • the product is generally applied to the hair with the aid of a cannula fitted on a container and then distributed over the hair with the aid of the applicator.
  • the application of the product makes it necessary to lift the arm above chin height and makes it uncomfortable to apply the product.
  • a“ cosmetic product” is understood to be a cosmetic product intended to be applied to a human being, for example a solid such as a powder, a liquid or a cream.
  • A“cosmetic product” is more generally a product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.
  • Applicators for applying a dyeing product to the hair comprising an applicator that receives the dyeing product before application on one side and a comb on the other side, are known from the patent applications JP 2004-154426, JP 2006-326081, CN 103704976 and CN 203483015.
  • An applicator that comprises a brush on each side, the brush being connected by a hinge, is also known from the application JP 2002-65336.
  • An applicator for applying a product to the hair, comprising a plurality of rows of application elements, the peripheral and central application elements not having the same flexibility, is also known from the application FR 2 876 255.
  • the applicator according to FR 2 876255 does not give complete satisfaction because the dyeing product can flow out of the applicator when applying the product on the hair. This issue might complicate the application of the product, for example by reducing the amount of product poured into the applicator and increasing the number of applicator fillings.
  • an applicator of longitudinal axis X for applying a product to the hair notably a dyeing product
  • a handle that allows the applicator to be gripped
  • an application member extending along a longitudinal axis X and comprising a body defining an application face which carries at least a four external rows of teeth and at least one internal row of teeth disposed between the four external rows, the teeth of the external rows are more flexible than the teeth of the internal rows and all the teeth of the external rows have the same shape.
  • Such an identical shape of the teeth of the external rows allows a large area of contact between the teeth and the hair and better retention of the product between the teeth. Moreover, the teeth of the external rows can build walls that retains the product all around the periphery of the applicator.
  • the applicator is safe and easy to use, with no fear of dropping any product. Thanks to the identical shape of the external teeth, a tank is formed to secure the product.
  • the applicator according to the invention makes it possible to apply the product uniformly along the length of the hair, the temples and the roots of the hair.
  • As internal rows of teeth extend between the external rows of teeth it possible to define, between the teeth, spaces that can receive the cosmetic product before it is applied to the hair. This allows better control over the quantity of product applied.
  • the invention also relates to a kit for hair coloration comprising a dyeing product and an applicator as described above.
  • a kit for hair coloration comprising a dyeing product and an applicator as described above.
  • Such a kit is easy to use for the consumer.
  • the invention also relates to a cosmetic process comprising:
  • the invention also relates to a cosmetic process comprising dipping an applicator in a bowl of a hair colour product and lifting the applicator for an application of the product on the hair.
  • the cosmetic process is a consumer self-application process.
  • the teeth are moulded in one piece with the body of the application member and are preferably made of an elastomer material so as to impart flexibility to the application member.
  • the application member can have a sufficient flexibility such that the teeth and/or the body of the application member can deform during the application of the product to the hair.
  • The“axis A” means the longitudinal axis A.
  • A“ cross section of a part of axis A” is a section perpendicular to the axis A of the part.
  • longitudinal axis of the partx denotes the line connecting all of the centers of mass of the cross sections of the part x.
  • A“ handle” is a gripping part.
  • length designates the longitudinal direction of a part of axis A
  • width designates the perpendicular direction
  • the teeth can be arranged in “rows” parallel to the longitudinal axis of the application member. But, the teeth of a“row” can also be arranged along any longitudinal axis. For example, the teeth of a “row” can also be arranged along an axis perpendicular to the longitudinal axis of the application member.
  • a row of teeth may have a non-rectilinear longitudinal axis, notably one that is curved, more notably with a single curvature.
  • a row comprises at least two teeth, preferably three teeth.
  • the spacing r between two consecutive teeth of a row is the same within one row and the same for all the external rows, as is illustrated.
  • An“external row” of teeth is a row delimiting the periphery of the pattern formed by the teeth.
  • the applicator comprises one or several of the following features taken in isolation or in any technically possible combinations:
  • All the teeth of the four external rows have a pyramidal shape, notably with a triangular base, more notably with a ridge that is oriented outward. Such a shape contributes to a better combing of the hair.
  • the teeth of the internal rows have a cylindrical shape, preferably with an angular profile from base to tip from which can vary from 0.5° to 5°.
  • the lock of hair engages with the product through the internal central row, and the lock is placed in contact with the product.
  • the application of product near the roots of the lock of hair is improved, and in addition, the lumps can be broken up between the internal teeth.
  • the product applied is more uniformly and more effectively.
  • An internal raw comprises between 2 and 5 teeth. Such a repartition of the internal teeth gives rise to product tank formation between the teeth.
  • All the teeth of the external rows have the same length, the length of a tooth being defined between its base and its distal end along its longitudinal axis
  • the external rows form a square with straight or curved sides, so as to give the user the benefit of using the applicator in all directions.
  • Such an arrangement of bristles helps to keep product within the platform while being applied at any angle.
  • the number of teeth of each external row is between 6 and 15. This range is optimal for highlighting streaks and strands.
  • the application face is curved, notably convex toward the outside.
  • the applicator is easier to move on the whole head.
  • the application member comprises a depression zone located on an exterior face opposite to the application face. This gives a comfortable depressed finger grip to help apply targeted hair strands. It also provides consumers with longer hair length, ease of application with an even deposition as the movement of hand is more in an arc, hence the radius of platform helps application during the arc movement of the hand.
  • the handle comprises lateral reinforcements, notably lateral reinforcements with a thickness (e) of between 0.1 mm and 5 mm.
  • the reinforcements improve the strength of the applicator and makes the hand movements more precise.

  • Figure 2 shows the position of the set of teeth 30 on the application face 21.
  • the face 21 and the arrangement of the set of teeth 30 on it are in a square profile in which, the length and breadth of the face is similar. This was developed specifically to allow the user to run the applicator in 360-degree direction, and not just perpendicular to the hair strands. It also helps in application of product on thinner strands, for highlights.
  • the application face comprises:
