Definitions

  • the present invention relates to devices for treating the hair, and more particularly, but not exclusively, those intended for shaping the hair, in particular for straightening, curling or crimping the hair, comprising a refill of cosmetic product.
  • the invention relates more particularly to devices comprising two jaws that are able to move with respect to one another and are able to take up a spaced-apart configuration for introducing a lock of hair between said jaws and a moved-together configuration for treating the lock, the jaws being movable along the lock in this moved-together configuration.
  • the jaws frequently carry two heating elements with which the hair is brought into contact during the use of the device.
  • hair straighteners consist of two arms that are connected together with the aid of a hinge which makes it possible to open and close said arms, and of at least one heating element disposed on the arms.
  • said lock is introduced between the two arms in the open position and then the two arms are closed manually over the lock of hair.
  • the lock of hair is then subjected to the heat output by the heating element, until the two arms are opened and the lock of hair is removed.
  • Application WO 2009/078046 describes a hairstyling appliance comprising two arms that are connected together so as to allow the appliance to be opened and closed, at least one heating member and at least one seat for accommodating a hair treatment device, the latter allowing a haircare product to be dispensed during operation.
  • the hair treatment device is composed of a support material impregnated with a haircare product and suitable for a single use.
  • WO 2009/015027 and US 2009/0025247 disclose a hair straightening device that makes it possible to apply a haircare product by contact with the hair.
  • the haircare product to be applied is contained in a removable refill for its application.

  • the applicator member can be inserted easily into the cavity and extracted with more difficulty. This makes it possible for the applicator member to be held therein properly.
  • the applicator member is inserted and extracted here along the same path but in opposite directions.
  • the coupling relief can be designed to damage the applicator member during the extraction of the latter.
  • the applicator member is not reusable, thereby making it possible to limit the health risks associated with its reuse.

  • the coupling relief 32 thus comprises a first portion 32 a that increases in size towards the bottom 42 and has a length l 1 and a second portion 32 b that decreases in size towards the bottom 42 and has a length l 2 .
  • the ratio of the lengths l 2 /l 1 is less than 0.2.
  • each coupling relief 32 in FIG. 11G is concave towards the outside.
  • FIG. 11H has coupling reliefs 32 in the form of tabs perpendicular to the insertion axis X disposed in an indentation 74 in the wall 34 or 36 .
  • These coupling reliefs are elastically deformable.
  • the coupling reliefs 32 can curve towards the bottom of the cavity 30 , such that the angle ⁇ becomes greater than 90°.
  • the coupling reliefs 32 can deform towards the opening 31 such that the angle ⁇ decreases and, by deforming, further compress the applicator member 26 , making its extraction more difficult.
  • the body 23 has, facing the coupling reliefs 32 , compression reliefs 76 .
  • said compression reliefs make it possible to compress said applicator member 26 against the coupling relief 32 facing it so as to further improve the retention of the applicator member 26 .
  • the compression reliefs 76 extend over the entire height H of the cavity 30 and have a symmetric shape about their median axis and in the form of a pad.
  • the coupling relief 32 is a bottom relief 42 which is in the form of an arrow with the tip 80 oriented towards the opening 31 of the cavity 30 .
  • the distal end 82 of the arrow extending along a length l 1 , is carried by a foot 84 of constant thickness. Said distal end widens from the tip 80 in the direction of the bottom 42 .
  • the foot 84 has a constant thickness and is less thick than the greatest thickness e max of the distal end 82 . Starting from the tip 80 towards the base of the foot 84 , the thickness increases along the length l 1 from the distal end 82 and is then constant along the length l 3 corresponding to at least a part of the foot 84 .
  • the distal end 82 may be in the shape of an inverted V, as illustrated in FIG. 11J , in the shape of a triangle, as illustrated in FIG. 11K , or in the shape of an inverted V with lips parallel to the bottom 42 at each of the ends of the V, as illustrated in FIG. 11L .
  • the distal end, as illustrated in FIG. 11M may have a recess 86 at the tip 80 .
  • the examples in FIGS. 12A to 12E differ from those in FIGS. 3 to 10 by way of the shape, in cross section, of the coupling reliefs 32 .
  • the coupling reliefs 32 may be in the shape of an isosceles triangle, as illustrated in FIG. 12 a , in the form of a semicircle, as illustrated in FIG. 12B , in the shape of a semi-polygon, in particular a semi-hexagon, as illustrated in FIG. 12C , or of a rectangle having a maximum width k that is greater than its maximum thickness e max , as illustrated in FIG. 12D .
  • the coupling relief 32 has a narrowed region 90 , in particular at its meeting point with the wall 34 . This narrowed region 90 can break when the user attempts to remove the applicator member 26 .
  • FIGS. 13A to 13C differ from those in FIGS. 3 to 10 by way of the position of the coupling reliefs 32 on the body 23 .
  • the body 23 comprises two coupling reliefs 32 that are respectively disposed on the opposite front 38 and rear 40 walls.
  • the body 23 comprises coupling reliefs 32 on a single one of the side walls 34 or 36 .
  • the body 23 comprises coupling reliefs 32 on the bottom 42 .
  • the body may comprise coupling reliefs on the opposite side walls, the front wall and the rear wall.
  • the applicator member may comprise at least two parts having different fibre densities and/or fibre orientations.
