Abstract
This invention relates to the packaging and subsequent removal of dry marking materials that tend to clump or bridge when shipped or stored in containers. Human operators are presently instructed to agitate such containers before installation into a marking engine but such agitation is unreliable. The present invention involves placement of agitation vanes on a displaceable inner seal within the cartridge such that such vanes will break apart clumps and bridges of the marking material during installation of the container upon the marking engine.
