Xerox Disclosure Journal
A combination toner supply bottle and toner waste receptacle is disclosed. A plastic bottle container, cylinder and the like for supplying toner having openings at opposite ends, top and bottom, is fitted with a flexible impermeable internal bladder which divides the inside of the vessel into two distinct chambers. The vessel is inserted into an electrophotographic copy or printing machine wherein the bottom chamber and opening dispenses toner to the developer housing while the top chamber serves as a receiver for waste toner and debris delivered from, for example, a photoconductor vacuum cleaning system, The change in volume of particles in the vessel is essentially constant or negative and, therefore, overflow is not a problem The combined toner supply/waste bottle reduces the internal space requirements of the copiedprinter and the number of discarded containers by fifty percent.
