Abstract
A toner cartridge for use in a copying machine for supplying fresh toner to the developer for the machine is disclosed as being formed with an elongated opening to permit discharge of toner when inverted. A removable flexible strip covers the opening and is detachably held to the cartridge by adhesive material. The strip comprises a flattened sleeve having the edges of one of its sides adhesively held onto the cartridge across the opening and a pulling member retained in the sleeve with one of its ends connected to one end of the sleeve so that a gradual pulling of the other end of the member progressively removes the sleeve as the same is turned within itself or inside out thereby carrying toner particles adhering to the sleeve within the sleeve.
