Title: Method of filling with powder a container that is closable by a lid, and associated apparatus for transferring said powder

Abstract: A method and apparatus for filling with powder a container having an interior and an opening to the interior that is closable by a lid. The method includes the steps of docking the opening in the container with a transfer apparatus including a powder-feed duct and dropping a coupling tube vertically downwardly through the duct to communicate with the interior of the container. The powder is passed vertically downwardly through said transfer apparatus downstream from the powder-feed duct through the coupling tube to said container, with the coupling tube serving to protect internal mechanical parts of said transfer apparatus. During the transfer, a low level of suction is maintained inside the transfer apparatus to avoid any accumulation of the powder and any release of the powder outside the apparatus.
