ABSTRACT:
Disposable toner cartridge for copying machine which has an outer casing with a first opening, and a container mounted within the casing and provided with a second opening. The container is movable between a position of containment of the toner, in which it is maintained during shipment, and a position of discharge, in which it is turned upon positioning of the cartridge in the copying machine and in which the first and second openings are aligned for discharging therethrough the toner into the copying machine. The casing is provided with clamping elements for clamping the container in the discharge position to prevent any subsequent movement of the container starting from the discharge position, so avoiding the re-use of the cartridge.
