| description | The present invention addresses the problem of providing a powder-filling system capable of filling a container with powder at an approximately uniform filling density. The system has: a hopper 11 having an opening 112 configured to be attached to the container 30 in a removable and hermetically closable fashion so that the hopper 11 communicates with the container 30 at the opening 112 for supplying powder to a container 30; a powder supplier 12 for supplying powder to the hopper 11; a gas supplier 13 for repeatedly supplying compressed gas in a pulsed form to the hopper 11, with the hopper 11 attached to the container 30 in a hermetically closed fashion; and a sieve member 113 provided at the opening 112 and having a smaller openings in a region near a side wall of the hopper 11 than in its central region. The smaller openings in the region near the side wall of the hopper 11 where the powder more easily falls from the hopper 11 into the container 30 impedes the fall of the powder in that region and improves the overall uniformity in the filling density. |
