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. Because of this arrangement, the dual fluid cartridge is very suitable and highly effective in situations where a dual fluid cartridge is needed to store and dispense fluids of unequal ratios (e.g. a 10:1 ratio, a 9:1 ratio, an 8:1 ratio, a 7:1 ratio etc.). 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.
