Abstract of Disclosure An ink cartridge comprises a box containing a plastic bag or bladder which is manufactured, filled and sealed in the controlled environment of a factory. As manufactured, the bladder has almost no chance of any substantial amount of air being entrapped therein. It has no openings, except for a small fill opening which is sealed immediately after the bladder is filled with ink. The bladder has rounded contours to prevent entrapment of gas and foreign substances. A plastic tube is welded to the outside of the bladder so that it may be penetrated and the bladder may be cleanly punctured within the tube in order to introduce the ink into the machine without simultaneously introducing air or other foreign matter into the ink. A special follower arrangement feeds a piercing tool into the plastic tube without buckling or kinking it.
