Abstract
An improved cartridge for containing a pellet of hot melt or phase change ink in an ink jet apparatus having at least one ink jet, a reservoir for containing and melting the hot melt or phase change ink from its solid state to a liquid state, and a receiver adapted to receive the cartridge, wherein the receiver includes an outlet at the base thereof for flowing liquified ink into the reservoir, and wherein the pellet is comprised of a size and shape so as to substantially fill the receiving means. The improvement consists of a hollow member of a predetermined geometry corresponding substantially to the geometry of the receiver, open at one end and deformable so as to permit the discharge of the pellet contained within the member through its open end, a retainer for the pellet, and a seal at the open end to protect against contamination of the ink.
