Abstract (en)
An apparatus for controlling filling of a container (116) from a hopper containing a supply of powder is provided. The apparatus includes a conduit (212) for guiding the powder from the hopper toward the container. The conduit is operably associated with the hopper. The apparatus further includes a pliable member (204) positioned at least partially within the conduit. The pliable member is positionable into a first position wherein a passageway is formed within the conduit and into a second position wherein the pliable member serves to block flow of powder through the conduit, whereby said pliable member may controllably permit and block the flow of powder thorough said conduit. <IMAGE>
