ABSTRACT:
The invention relates to a distributor-container for supplying powdered solid products or the like to a utilization apparatus such as an electrostatic powder projector, in which a substantially constant level of powder and therefore a substantially constant rate of flow of fluidized powder, is maintained in the distributor-container irrespective of the height of the fluidized powder in an outer container in which the distributor-container is immersed. The two containers are connected through a lock-chamber located at the height of said constant level, and closure members for the ends of the lock-chamber operate so as to introduce powder into the distributor container only when the level of powder in the distributor container is below the uppermost level of the powder in the end of the lock-chamber opening into the distributor-container.
