Abstract
Abstract To facilitate the refilling of a fluid toner into a toner container of a printing of copying device, a toner refill container (16) is used which has a nozzle (20), whose opening is sealed by a foil (5), which can be removed from the nozzle edge (7) by a tear-open or tear-off cord (6) after a coupling ring (17) of the toner refill container (16) has been inserted into the filler neck (22) of a toner container (23). Moreover, the tear-open or tear-off cord (6) is led from the inside of the toner container (23) through a guide channel (18) to the outside.
