Abstract
A refurbished toner cartridge includes a cover having elongated side dimensions with integral flanges and a mating bottle also having elongated side flanges, the flanges bonded to create an interior volume for holding a print toner. At one end of the cartridge is a toner fill opening which enables access into the interior volume. The refurbished cartridge further comprises a flexible bladder that is inserted through the fill opening and is positioned within the interior volume of the cartridge. Toner is contained in the bladder and is released upon the bladder being ruptured by user actuation of either an internal knife blade or a pull string attached to the bladder.
