ABSTRACT:
A cartridge in which marking particles used in an electrophotographic printing machine are stored. The cartridge has an opening in the surface thereof for discharging the marking particles therefrom. A flexible sealing strip is secured removably to the cartridge and seals the opening in the surface to prevent the discharge of the marking particles. The sealing strip is folded back over itself in juxtaposition. A flexible backing strip has the portion of the sealing strip folded back secured thereto. As the sealing strip is removed from the cartridge, successive portions thereof are secured to the backing strip. The foregoing occurs automatically when the cartridge is inserted in a dispensing unit of the printing machine and rotated. In this way, the cartridge is sealed when inserted in the printing machine and, after being rotated, automatically opened to discharge marking particles into the dispensing unit of the printing machine.
