  • Patent number: 10350567
    Abstract: Each capsule comprises a liquid core (14) and a gelled shell (16) comprising a gelled polyelectrolyte completely encapsulating the liquid core (14) at the periphery thereof. The gelled shell (16) is suitable for retaining the liquid core (14) when the capsule (12) is immersed in a gas. The liquid core (14) comprises an intermediate drop (18) of an intermediate phase, the intermediate phase being placed in contact with the gelled shell (16), and at least one internal drop (20) of an internal phase placed in the intermediate drop (18). The ratio of the volume of the core (14) to the volume of the gelled shell (16) is greater than 2, advantageously is greater than 50.

  • Patent number: 9446425
    Abstract: The device (110) for dispensing a fluid composition includes: a container (30) containing a heterogeneous mixture (14); a member (34) for dispensing the fluid composition; a delivery element (32) including: a fluid guide conduit (42) defining an axis (A-A?) for the flow of fluid through a central passage (50); a filtration member (44) configured so that the heterogeneous mixture (14) inserted into the guide conduit (42) passes through the filtration member (44); the filtration member (44) including at least one openwork filtration wall (56) delimiting a plurality of filtration openings (58); the heterogeneous mixture (14) including particles (20) in suspension, the filtration openings (58) having a transverse expanse smaller than the mean diameter of the particles (20) in suspension; and the particles (20) in suspension being formed by beads.
