In an electrophotographic printing machine, residual toner particles adhering to the photoconductive surface after the transfer of the toner powder image to the copy sheet are cleaned therefrom by a cleaning system. The waste toner is transported to a waste container. Hereinbefore, waste containers were srnal I , rigid disposal plastic containers. Containers of this type were relatively expensive because shipping costs were high since they occupied a large volume. Thus, it is desirable to decrease the volume occupied by the waste toner containers when in the unfilled, shipping condition. If the waste toner container occupied a smaller volume, a greater number of containers could be shipped and the relative cost associated with each container for shipping could be substantially reduced. To achieve the foregoing, the waste toner container is collapsible. The container includes a collapsible cardboard box with an auto-folding bottom. A plastic film liner is mounted internally in the cardboard box. The cardboard box with the plastic liner already installed is shipped in a collapsed state. In this way, the box occupies a relatively small volume. Immediately prior to being used, the auto-bottom.box is unfolded and locked open in a usable state. I t is necessary to have a large opening in the plastic liner bag to allow air to enter into the open plastic liner. If sufficient air cannot get into the plastic liner bag, then the liner bag will not open as required when the box is opened. It is also necessary to reach inside the plastic liner bag to make sure that the bag and box are fully open. The large opening is sealed by adhesive tape, zip lock or other methods which prevent the leakage of toner particles from the container. A small opening in the bag may be required for depositing the waste toner particles therein. This srnall opening may be sealed with tape, if required, after the bag and box are filled with the waste toner particles.
