They then actuate the manipulating member 76, moving it longitudinally by pushing the button 100 towards the outlet opening 88.

  • users dip the mixing member 27 into a dose of second cosmetic product 14. They move the mixing member 27 in the dose of second cosmetic product 14 which causes detachment of the first cosmetic product 12 carried by the mixing member 27 and mixing thereof with the second cosmetic product 14.

  • the fifth kit 120 comprises an auxiliary container 122 containing the first cosmetic product 12, in addition to the container 18 containing the second cosmetic product 14.
  • the mixer 16 advantageously has a retaining surface 124 capable of retaining a dose of the first cosmetic product 12.
  • This surface 124 is for example a rough surface of roughness (Ra) greater than 1 .6 ⁇ with a Charmille grade surface finish higher than 24, or an adherent surface.
  • the surface 124 is a porous surface.
  • the surface 124 is advantageously located on the mixing parts 26 and optionally on the rod 24.
  • the functioning of the fifth kit 120 differs from the functioning of kits 10, 50, 60, 70 in that initially the mixer 16 does not carry any first cosmetic product 12.
  • the retaining surface 124 is dipped into the first cosmetic product 12, which causes mechanical attachment of a dose of first cosmetic product 12 onto the mixer 16.
  • the mixer 16 thus carrying the first cosmetic product 12 is then dipped into a dose of second cosmetic product 14 extracted from the container 18 or contained in this container 18.
  • the mixer 16 of the fifth kit 120 may be similar to any of the mixers 16 described above for kits 10, 50, 60, 70.

  • the mixer 16 illustrated in figure 9 comprises a longitudinal rod 24 and two mixing parts 26 of semi-torus shape 132 joined to the rod 24 by a common transverse section 130.
  • the common section 130 is joined to the distal end 30 of the rod 24.
  • Each semi- torus 132 extends substantially over a plane perpendicular to the rod axis A-A'.
  • the mixing parts 26 therefore extend either side of an axial or median plane passing through axis A-A' and through the common transverse section 130.
  • the mixer 16 illustrated in figure 10 comprises four mixing parts 26.
  • the mixing parts comprise two curved lugs 32 positioned either side of axis A-A' of the rod 24 and two curved lugs 140 positioned in a plane perpendicular to the plane of the lugs 32.

  • the mixer 16 illustrated figure 1 1 comprises two mixing parts 26 which project transversally either side of the axis A-A' of the rod 24.
  • the mixing parts 26 have a width which increases the more they draw radially away from the axis A-A', either side of this axis and as far as a free edge 142. Therefore each mixing part 26 is in the shape of a substantially trapezoid propeller blade in figure 1 1.
  • the mixer 16 illustrated figure 12 comprises three mixing parts 26 distributed substantially angularly about the axis A-A'.
  • the mixing parts 26 project radially from the free end 30.
  • the mixing parts 26 are formed of petals which, when seen in cross-section in an axial plane passing through the axis A-A', draw away from axis A-A' radially and continually as far as their free edges 142, and draw axially away from the free end 30 as far as their free edge 142.
  • each mixer 16 can be pre-loaded with first cosmetic product 12 at the time of manufacture of the mixer 16, or the cosmetic product 12 can be loaded by the user.
  • the fact that the intermediate space 38 delimited between the mixing parts 26 is clear means that even when the mixer 16 is pre-loaded with the first cosmetic product 12, the first cosmetic product 12 carried by the mixing parts 26 does not bridge the space between any two of the mixing parts 26. In particular, the first cosmetic product 12 does not connect between them any portions of any two mixing parts which are not connected between them in the absence of the first cosmetic product 12.
  • solid means that no collapse of the composition is observed when it is outside of a container comprising it, in the absence of a mechanical or thermal stimulation, in particular heating.
  • the word "solid” is used to define a composition for which the stress measurement is comprised between 5000 and 50 000 Pascals (N.m 2 ).
  • the stress measurement is measured at room temperature (20-25 q C), after penetration with a flat cylindrical stainless steel spindle of 6 mm (or 12 mm) in diameter, into the matrix of the composition to a depth of 0.4 mm at a speed of 1 mm/s, relaxation for 1 second and removal of said spindle from the matrix of the composition at a speed of 1 mm/s, the stress being measured with a texture analyser of the "TA-XT2" type sold by the company RHEO.
  • the stress is preferably comprised between 10 000 and 40 000 Pa and even more preferably between 15 000 and 35 000 Pa.
  • the mixer 16 is pre-loaded with the dose of first cosmetic product 12 by dipping the mixer 16 into a first cosmetic product in the form of a powder mixed with a volatile liquid and by evaporating the liquid, after dipping, in order to leave only the powder attached to the mixer 16.
  • the evaporation is for example obtained by sucking up the liquid.
  • the mixer can be pre-loaded with a dose of a first cosmetic product over at least part of its outer surface by dipping the mixer into the cosmetic product.
  • the first cosmetic product applied to the outer surface of the mixer advantageously to a mixing part, is a solid.
  • This solid can be obtained e.g. by dipping the outer surface into a volume of a first cosmetic product in the form of a powder, in the form of a powder mixed with a volatile liquid, or in the form of a liquid which solidifies on the outer surface.
  • the mixer is then pre-loaded with a solid dose of the first cosmetic product.
