Abstract
A powder dispensing apparatus is disclosed in which the apparatus includes a drum assembly 2. The drum assembly includes a support portion 10 and a foil 14 which are linearly movable relative to one another. The foil 14 has a plurality of through-apertures 25, and the support portion 10 includes a corresponding number of apertures 20. The base of each aperture 20 in the support portion is closed off by a piston 24. The apertures 25, 20 are aligned at a filling position where powder can fill a compartment. The foil 14 is then translated relative to the support portion 10 in order to close the compartments. The drum 2 can be rotated through 180° to a dispensing position. The foil 14 is moved so that the apertures 25, 20 are aligned and the pistons 24 can be used to dispense powder into a receptacle.
