- the fixing bracket 94 comprises a retaining tongue 98 arranged parallel to the external surface and a base 100 connecting the tongue 98 to the external surface.
- the tongue 98 protrudes towards the axis A-A' from the base 100. It here has a free edge with a concave contour corresponding to the contour of the insertion hole 54 (see figure 8 ).
- the base 100 defines a locking surface 102 located under the tongue 98 in order to partially close the intermediate space 96 and block in rotation the stop 86A, 86B of the insert 30, when the stop 86A, 86B is inserted into the intermediate space 96.
- each stop 86A, 86B of the insert 30 cooperates with a complementary stop 88A, 88B of the distribution nozzle 28, by being inserted into the intermediate spaces 96, delimited by each one of the two complementary stops 88A, 88B with the outer plate 52.
- the insert 30 In mounted position, the insert 30 is as such immobile in translation along the axis of insertion A-A' of the insert 30, in the insertion hole 54 of the intermediate part 46.
- each stop 86A, 86B is angularly offset with respect to the corresponding complementary stop 88A, 88B.
- the base 30 can be moved in translation along the axis A-A'.
- first reservoir 12 and the second reservoir 14 are filled respectively with the first cosmetic product and with the second cosmetic product in the receptacle 16.
- the diffuser 26 is placed on the assembly band 24 which is then assembled on the neck 18.
- first upstream section 40 and the second upstream section 42 are respectively connected on the distribution members 22 of the first reservoir 12 and of the second reservoir 14.
- the intermediate part 46 is mounted in the external skirt 44, with the free edge 48 of the skirt 40 being inserted in a sealed manner into the peripheral groove 66 of the sealing edge 64.
- a suitable sealing is as such created around the external skirt 44, despite its extended shape, thanks to the application of the sealing edge 64 on the free edge 48.
- the free edge 48 of the external skirt 40 is received between the central body 50 and the sealing edge 64 of the intermediate part 46.
- the insert 30 is initially in an unassembled position outside of the distribution nozzle 28.
- the user grasps it and inserts it into insertion hole 54 of the intermediate part 46, by displacing it in translation along the axis A-A' to the intermediate position.
- the user grasps the grasping members 82 on the nozzle 70 of the insert 30.
- the user rotates the insert 30 about the axis of insertion A-A' in order to reach the mounted position in the distribution nozzle 28.
- each stop of the insert 30 cooperates with a complementary stop 88A, 88B of the intermediate part 46.
- Each ramp 90 of a stop 86A, 86B is progressively inserted into the intermediate space 96 under a tongue 98 of a complementary stop 88A, 88B providing through the cam effect, a pushing of the insert 30 along the axis A-A' inwards.
- each stop 86A, 86B is inserted into the intermediate space 96 and bears under the tongue 98.
- the insert 30 is blocked in rotation in one direction and is immobilized in translation outwards along the axis A-A' via cooperation between each stop 86A, 86B and the corresponding intermediate stop 88A, 88B.
- the stop 86A, 86B and the intermediate stop 88A, 88B form a blocking mechanism 32 of the "bayonet" type.
- the seal between the insert 30 and the intermediate part 46 is effective, despite the horizontally extended shape of the distribution nozzle 28.
- the user grasps the receptacle 16 and presses the mobile member 34.
- the displacement of the mobile member 34 causes the simultaneous movement of the first upstream section 40 and of the second upstream section 42 and the activation of the distribution members 22. This generates the simultaneous distribution of the first cosmetic product from the first reservoir 12 and of the second cosmetic product from the second reservoir 14.
- the first cosmetic product and the second cosmetic product rise respectively through the first upstream section 40 and through the second upstream section 42 in order to reach the upstream chamber for collection 62.
- the products are joined together and penetrate into the insertion hole 54 into which the internal portion of the insert 30 is inserted.
- the flow of the first product and the flow of the second product are each separated horizontally by the longitudinal wall 72 and are combined on either side of this wall 72.
- the flows are offset laterally with respect to the axis A-A' and follow a winding path as a zig-zag until a through-hole 81 is reached.
- the flows of cosmetic products therefore follow both a winding horizontal path in the form of a zig-zag on either side of the longitudinal wall 72 by progressing along the axis A-A', but also a vertical path perpendicular to the longitudinal wall 72 through the successive through-holes 81.
- the mixture of the first cosmetic product with the second cosmetic product is therefore particularly effective, in light of the turbulences generated, and this despite the high viscosities of the of the first cosmetic product and of the second cosmetic product.
- the respective output speed of the first cosmetic product and of the second cosmetic product outside of the reservoirs is about 2 m/s.
- the Reynolds number of the first cosmetic product is then about 0.2 for a viscosity of 10,000 mPa.s and the Reynolds number of the second cosmetic product is about 0.4 for a viscosity of 5,000 mPa.s.
- the global restitution speed is about 0.2 m/s at the output of the distribution nozzle 28.
- the flow in the nozzle 28 is purely laminar and no mixing will take place between the first cosmetic product and the second cosmetic product.
- the presence of the mixer 68 ensures a very effective mixing, thanks to the winding displacement in three dimensions in the mixer 68, making it possible to form the composition and the end of its passage in the insertion hole 54.
- the presence of the intermediate part 46 provides a seal of the distribution nozzle 28 thanks on the one hand, to the complementary cooperation between the sealing edge 64 and the free edge of the external skirt 44 and thanks to the simple shape of the insertion hole 54 corresponding to the simple shape of the insert 30.
- the insert 30 in mounted position, is immobilized in translation along the axis of insertion A-A' in the direction of distribution of the cosmetic composition, as such avoiding any ejection during the distribution.
- the distribution of the composition is therefore highly reliable, even if the viscosity is high.
- the insert 30 is again displaced in rotation about the axis A-A', from its mounted position on the distribution nozzle 28, to the intermediate position in which each stop 86A, 86B is angularly offset from the corresponding complementary stop 88A, 88B. Then, the insert 30 is extracted in translation along the axis A-A' outside thereof in order to be removed from the insertion hole 54.
- the insert 30 can be cleaned easily, guaranteeing a sustainable use of the device 10.
- the intermediate part 46 and the insert 30 are assembled permanently to one another.
- the insert 30 cannot be removed with respect to the intermediate part 46.
- the distribution cannula is made of a single piece. The first portion and the second portion of the distribution cannula are then in a single piece.
- the sealing edge 64 is carried by the external edge of the external skirt 44.
- the edge 64 is engaged in a sealed manner around the first portion of the distribution cannula during the engagement of the distribution cannula with the external skirt 44.
- the external skirt 44 of the distribution nozzle 28 defines an inner passage that has a first circular transversal section, and the inner channel of the distribution cannula has a second circular transversal section, with a surface area that is different from the surface area of the first transversal section.
- This change in section allows for example for a distribution in a sheet of the cosmetic product.
- the surface area of the first transversal section defined by the inner passage of the external skirt 44 is less than the surface area of the second transversal section defined by the internal channel of the distribution channel.
- the use of a distribution cannula having an internal channel with a transversal section that is different from the transversal section of the internal passage of the distribution nozzle performs a transition between the two transversal sections, by guaranteeing an excellent seal between the cannula and the nozzle.
