Abstract: A dual fluid cartridge for storing and dispensing fluids in unequal ratios is disclosed. The dual fluid cartridge disclosed defines two fluid chambers for a fluid to be held in greater amount and defines another fluid chamber for a fluid to be held in lesser amount. The two fluid chambers holding the fluid of greater amount are in fluid communication with one another through a delivery channel.

With such an arrangement, the amount of space wasted in the cartridge is minimized, which maximizes the amount of fluids that can be stored in the cartridge. As a result, the total final product that can be dispensed from the dual fluid cartridge is also maximized.
