Abstract

A fluid mixture dispensing system using a membrane to seal multiple reservoirs is disclosed. The multiple reservoirs each contain a respective ingredient. The reservoirs are coupled to respective orifices in a plate. The respective ingredients are dispensable via the respective orifices. The membrane seals the respective orifices. The ingredients are dispensed into one or more channels formed between the membrane and the plate. In specific embodiments, the membrane is an integral part of a cartridge which contains the multiple reservoirs. In specific embodiments, the cartridge includes an inlet and an outlet. A solvent flows from the inlet to the outlet through the one or more channels, and the ingredients are dispensed into the solvent in the one or more channels.
