A cylindrical-shaped particle dispenser cartridge includes a dispenser nozzle. The dispenser nozzle outer surface includes sealing ribs that surround an included nozzle opening. The dispenser nozzle is arranged to engage a shutter that slides over the sealing ribs, thus sealing the nozzle opening. When the cartridge rotates about the cartridge axial in a shutter-opening or leading direction (X) with respect to the shutter, the sealing ribs move in a like direction with respect to the shutter, thus unsealing the particle dispenser cartridge nozzle opening. The dispenser cartridge is arranged to dispense particles such as, for example, toner particles. The dispenser nozzle outer surface includes outer shutter rails disposed on inboard and outboard sides of the sealing ribs.
