DEVICE AND METHOD FOR CONTROLLING THE FLOW OF A POWDER

摘要

An apparatus (100) for filling a receptacle with a powder comprises a hopper (105) adapted to contain a powder pharmaceutical formulation (115), the hopper comprising an outlet (120). A vibratable member (135) is positioned in, on, or near the hopper so that the vibratable member is spaced from powder in the hopper, and the vibratable member is capable of fluidizing the powder in the hopper. Powder flowing through the outlet under the control of the vibratable member flows into a receptacle (175) or into a transfer chamber (125) for transport to a receptacle.
