Abstract
A powder packing apparatus of the present invention is capable of sending a gas uniformly into powder to thereby fluidize the powder with a minimum amount of gas. The gas conveys the fluidized powder to the bottom of a container that may have a small mouth or a sophisticated configuration. The gas present in the powder introduced in the container is released via a powder layer between a nozzle and the mouth. The apparatus can therefore easily, densely pack the container with the powder without causing the powder to fly out of the container. Further, the apparatus is miniature, easy to carry and easy to operate and can therefore be handled by any person at any plate.
