Zusammenfassung: | A device for dispensing a fluid topical composition includes a reservoir (102) storing the composition and dispensing a pressurized flow of the composition. The device also includes an accumulator (108) having an expandable chamber (109) in fluidly communication with the reservoir (102). The chamber (109) is biased towards a deflated configuration so that, when filled with the composition the chamber (109) expands against this bias applying pressure to the composition stored therein. The device includes a supply valve (104) regulating the flow of the composition from the reservoir (102) to the accumulator (108), and a pressure sensor (106). The device further includes a processing arrangement (112) analyzing data from the sensor (106) to determine whether pressure in the accumulator is above a predetermined threshold and controlling the supply valve (104) to maintain the pressure within a desired pressure range. The device also includes a deposition arrangement (110) dispensing the composition from the accumulator under control of the processing arrangement (112). |
