Abstract: Method and device for metering and dispensing viscous or partly fluid materials in which the fluid material is flowed downwardly as a column through a tube, is separated into portions by injecting gas into the column to form bubbles spaced along the length of the fluid column and discharging the separated portions from an outlet opening of the tube. The apparatus includes a tube together with a controlled fluid material supply, a gas supply, a gas inlet for generating bubbles to separate fluid passing through the tube into portions and an outlet from the tube for discharging separated portions of fluid. The fluid portions may be collected and maintained separate by deposition in a displaceable medium such as air, liquid or powder, or by separate containers for each portion. The portions deposited in powder may pick up powder in the form of a non-tacky coating.
