Abstract: The invention relates to a recipient (1) for ex-vivo treatment of biological liquids, which includes: a rigid body (2); a reservoir (3) provided inside the body (2), which is formed by a side wall (4), a rigid upper wall (5) and a rigid lower wall (6) and has an internal thickness defined by the separation between the upper wall (5) and the lower wall (6), at least one of the upper wall (5) or the lower wall (6) having a window area (7) configured to allow the passage of electromagnetic radiation from outside of the body (2) to the reservoir (3); two ports (8, 9) for liquids to gain access to the reservoir (3) from outside of the body (2); and closure means (10, 11) for the ports (8, 9), the closure means (10, 11) being configured to provide, jointly, the reservoir (3) with hermetic sealing against gases and liquids.

Abstract: The present invention relates to a device (1) for the administration of a cosmetic product, with a first holder (2) for a pressurized gas cartridge (3), a second holder (4) for a cosmetic product container (5), flow rate regulating means (6), a nozzle (7) with heating means (8), and a trigger (9) which allows opening the passage of gas when operated. The first holder (2) allows housing a cartridge (3) for the passage of pressurized gas towards the flow rate regulating means (6). The first holder (2), the flow rate regulating means (6) and the nozzle (7) are fluidically connected. The regulating means are located downstream of the first holder (2) and upstream of the nozzle (7). The second holder (4) allows housing a container (5) for the passage of a product towards the nozzle (7) by means of a first conduit (10). The invention also relates to the corresponding process, use and container.
