1. A device for dispensing a fluid composition, comprising: a container containing a heterogeneous mixture;a delivery element positioned in the container, to convert the heterogeneous mixture into the fluid composition;a dispenser for dispensing the fluid composition outside the device;the delivery element comprising: a fluid guide conduit, comprising an upstream opening designed to open into the container, a central passage, and a downstream opening connected to the dispenser, the guide conduit defining a fluid flow axis through the central passage between the upstream opening and the downstream opening;a filtration member, mounted in the guide conduit, the filtration member being configured so that the heterogeneous mixture flowing into the guide conduit through the upstream opening passes through the filtration member;the filtration member comprising at least one openwork filtration wall delimiting a plurality of filtration openings, the filtration wall forming a non-zero angle with a perpendicular to the flow axis;the guide conduit has an upstream restrictor, positioned between the upstream opening and the filtration member, the guide conduit having a downstream segment with a transverse expanse, considered relative to the flow axis, larger than the transverse expanse of the upstream restrictor;the heterogeneous mixture comprising particles in suspension, the filtration openings having a transverse expanse smaller than the mean diameter of the particles in suspension, andthe particles in suspension being formed by beads comprising a core and a gelled envelope. 2. The device according to claim 1, wherein the filtration wall is inclined relative to a perpendicular to the flow axis. 3. The device according to claim 2, wherein the filtration member assumes a conical or frustoconical shape with an axis parallel to or combined with the flow axis. 4. The device according to claim 1, wherein the filtration wall extends along the flow axis. 5. The device according to claim 4, wherein the filtration wall is cylindrical, with an axis parallel to or combined with the flow axis. 6. The device according to claim 1, wherein each filtration opening has a size larger than 0.1 mm. 7. The device according to claim 1, wherein the dispensing member is a pump. 8. The device according to claim 1, wherein the transverse expanse of each filtration opening is smaller than one third of the mean diameter of the particles in suspension. 9. The device according to claim 1, wherein the filtration openings have an elongated shape. 10. The device according to claim 1, wherein the volume of an upstream part of the central passage situated upstream from the filtration member in the central passage is greater than a maximum volume of all residues recovered during a disintegration of the particles in suspension. 11. The device according to claim 1, wherein the surface area of each filtration opening is smaller than a minimum surface area of each residue from among all of the residues recovered during a disintegration of all of the particles in suspension. 12. The device according to claim 1, wherein the total surface area of the filtration openings is greater than 0.2%, of a total surface area of the residues recovered during a disintegration of all of the particles in suspension. 13. A method for dispensing a fluid composition, comprising the following steps: providing a device according to claim 1, containing a heterogeneous mixture;actuating the dispensing member to drive the heterogeneous mixture into the delivery element;converting the heterogeneous mixture into the fluid composition in the filtration member;dispensing the fluid composition through the dispensing member outside the device. 14. The method according to claim 13, wherein the heterogeneous mixture comprises particles in suspension, the method comprising the disintegration of the particles in suspension in the delivery element to obtain the fluid composition. 15. The method according to claim 14, wherein the disintegration of the particles in suspension is done before the passage in the filtration member, the disintegration of the particles in suspension comprising the formation of a residue, the residue being retained on the filtration member. 16. The device according to claim 7, wherein the pump is selected from the group consisting of a membrane pump and a piston pump. 17. The device according to claim 1, wherein the transverse expanse of each filtration opening is smaller than one quarter of the mean diameter of the particles in suspension. 18. A delivery element for converting a heterogeneous mixture into a fluid composition and positioned in a container containing the heterogeneous mixture, the delivery element comprising: a fluid guide conduit, comprising an upstream opening designed to open into the container, a central passage, and a downstream opening designed to be connected to a dispenser for dispensing the fluid composition outside the container, the guide conduit defining a fluid flow axis through the central passage between the upstream opening and the downstream opening;a filtration member, mounted in the guide conduit, the filtration member being configured so that the heterogeneous mixture flowing into the guide conduit through the upstream opening passes through the filtration member;the filtration member comprising at least one openwork filtration wall delimiting a plurality of filtration openings, the filtration wall forming a non-zero angle with a perpendicular to the flow axis;wherein the guide conduit has an upstream restrictor, positioned between the upstream opening and the filtration member, the guide conduit having a downstream segment with a transverse expanse, considered relative to the flow axis, larger than the transverse expanse of the upstream restrictor; andwherein the upstream restrictor comprises an inner radial protrusion. 19. The delivery element according to claim 18, wherein the inner radial projection is annular.
