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