ABSTRACT:
A cartridge for dispensing metered amounts of liquid electrophotography toner concentrate. The cartridge comprises first and second endcaps within a hollow of the cartridge for confining the concentrate; a tube rigidly attached to the first endcap having a passage therein for allowing expulsion of the concentrate when pressure is applied to the concentrate by the first endcap; and a first and second control lip rigidly attached to the tube for metering the expulsion of concentrate out through the passage. In an alternate embodiment, the first endcap is a diaphragm whereby the bowing capacity of the diaphragm meters a controlled amount of concentrate out through the passage. A pressurized medium or vacuum acts upon the first endcap to effectuate a pumping of the concentrate out through the passage for mixing with a carrier fluid.
