Abstract
In a powder filling method for supplying the powder from a powder supply hopper into a container, the air inside the hopper and/or the container is pressured and then restored to an atmospheric pressure by discharging the pressured air in the hopper and/or the container. With this method, even a powder of an inferior filling performance can be filled into a container to a high density.
