- the filtering member 44 comprises at least one perforated filter wall 56 delimiting filtration openings 58, forming a non-zero angle and advantageously greater than 10 ° with a perpendicular to the axis AA 'of circulation.
- the perforated filter wall 56 is conical. It thus forms an angle greater than 30 °, advantageously greater than 45 ° with the perpendicular to the axis A-A 'of circulation.
- the perforated filter wall 56 comprising a plurality of openings 58 is further inclined with respect to the axis A-A 'of circulation, to ensure a tangential filtration.
- the perforated filter wall 56 projects downstream into the central passage 50. It has a base 60 of section greater than or equal to that of the downstream opening 54 to surround the downstream opening 54 and a free end 62 disposed in the passage 50.
- the filtration member 44 is arranged in the guide duct 42 so that all the heterogeneous mixture 14 introduced into the central passage 50 through the upstream opening 52 passes through the perforated wall 56 and its openings 58, before to reach the downstream opening 54. This allows the formation of the fluid composition 12 and the retention on the perforated wall 56 residues resulting from this formation.
- the filter member 44 is cylindrical in shape of axis A-A '.
- the filter wall 56 thus comprises at least one section parallel to the axis A-A ', suitable for tangential filtration.

- the dispensing member 34 is for example formed by a pump 80 capable of causing aspiration of the heterogeneous medium 14 into the delivery element 32, then passing this medium 14 through the filtration member 44 to form the composition 12, and finally to convey the composition 12 to a dispensing orifice 82 located on the member 34 towards the outside of the device 10.

- the mixture 14 is then pumped through the upstream opening 52 and back into the hollow tubular body 46 of the guide duct 42 to the filtration member 44.
- the particles 20 when the particles 20 are rigid, they block against the wall 56 in the intermediate space delimited between the perforated wall 56 and the body 46 of the duct 42. Only the homogeneous medium 18 liquid passes through the openings 58 of filtration. The homogeneous medium 18 thus forms the fluid composition 12 which rises through the downstream opening 54, the distribution channel 84. This composition is extracted through the dispensing orifice 82 out of the device 10, for example in the form of a jet or a spray.
- the particles 20 disintegrate in contact with the perforated wall 56. Their contents pass through the openings 58 and form, by mixing with the medium 18, the fluid composition 12. The solid residue resulting from the disintegration of the particles 20 is blocked by the perforated wall 56.
- the delivery element 32 according to the invention thus very effectively filters a heterogeneous mixture 14 to form a fluid composition 12 to be distributed in a standard dispensing member 34 and low cost.

- the upstream restriction 1 12 furthermore includes an internal radial projection 116 intended to break up the particles 20 in order to homogenize the heterogeneous medium 14.
- the internal radial projection 1 16 is preferably annular. It projects from the wall of the conduit 42 defining the restriction 1 12. It defines a central lumen 1 18 through which the medium 14 passes, with a transverse extension smaller than the average diameter of the particles 20 (see FIG. 6).
- the height of the restriction 1 12 is less than the height of the downstream section 1 14, taken along the axis A-A '. This height is advantageously less than 50% of the height of the downstream section 1 14, especially less than 20% of the height of the downstream section 1 14.
- the downstream section 1 14 receives the filter member 44.
- the free end 62 of the perforated wall 56 is located at an axial distance from the restriction 1 12 along the axis A-A '.
- the minimum transverse extent of the downstream section 1 14 is greater than 1.5, in particular greater than 2.5 times the average diameter of the particles 20. It is thus greater than 200%, in particular 300% of the minimum transverse extent of the restriction. 1 12.
- downstream section 1 14 has a substantially constant inner cross section.
- the operation of the second device according to the invention 1 10 differs from the operation of the first device 10 according to the invention in that the passage of the particles 20 in the restriction 1 12 aligns the particles 20 to advantageously place them in single file, which facilitates their aspiration. Then, the projection 1 16 present in the restriction 1 12 produces their disintegration.
- the envelope 24 of the particles 20 breaks in the restriction 1 12 to the passage of the projection 1 16, releasing the heart 22.
- the core 22 thus mixes with the medium 18 to form the fluid composition 12 which passes through the filtration member 44.
- the envelope 24 forms a semi-solid residue 120 which is retained by the filtration wall 56 without passing through the openings 58.
- the delivery element 32 is therefore effective both for forming the fluid composition 12 by releasing the core 22 in the restriction 1 12 and for very effectively retaining the remaining residue 120 of the envelope 24.
- the residue 120 of the envelopes 24 is held little by little in the upper part of the filtering member 44. It thus accumulates without completely clogging the filtering member 44, until all the contents of the dispensing device 1 10 is used.
- the particles 20 disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and at least a portion of the particles 20 disintegrate in contact with the filter member 44.
- the particles 20 partially disintegrate during the passage in the restriction 1 12, in contact with the projection 1 16, and end to disintegrate in contact with the filter member 44.
- a fluid composition 14 homogeneous, without any debris is thus delivered through the dispensing orifice 82, without producing debris unfavorable to the feel of use to the touch of the composition delivered, for example on the skin of a user, or produce debris that can block the dispenser member
- the volume of the upstream portion of the central passage 50 situated upstream of the filtration member 44 in the central passage 50 is greater, and is in particular greater than 1.5 times the maximum volume of the residues 120 intended to be recovered during of the disintegration of the particles in suspension.
- the maximum volume of the residues 120 is for example estimated by the sum of all the volumes of the envelopes 24 of the particles 20 contained in the heterogeneous mixture 14, received within the container 30.
- the free volume in the skin filter thus makes it possible to store all the semi-solid residues resulting from the disintegration and filtration of the heterogeneous starting mixture.
- the term “disaggregate” preferably means that the particles are torn, exploded, opened, and / or broken, thereby losing their integrity and releasing where appropriate their contents, as opposed to breaking a clump. of particles to obtain free particles maintaining their integrity.
- the volume delimited by the central passage and the filtering member 56 is greater than 1.5 the maximum volume occupied by all the residues 120 contained in the container 30.
- each filter opening 58 is smaller than the minimum area of each residue 120.
- the filtration openings 58 are advantageously of elongate shape, with the smallest dimension, here the width, less than a quarter of the diameter of the particles 20.
- the openings have a large surface, which allows a good return of the product to be delivered, but are also thin enough to prevent residues 120 to pass through the filter, even if they fold on themselves.
- the total area of the filtration openings 58 is greater than 0.2% and especially less than 10% of the total surface of the residues 120 contained in the container 30.
- the term "surface” applied to a residue 120 means the maximum surface area of all the surfaces measured over all the projections of this residue 120 on a plane, advantageously on the filter wall 56 of the filtering member 44.
- the free end 62 of the perforated filter wall 56 is axially spaced from the upstream opening 52.
