A method is provided for filling a container system for a cosmetic product that has a hollow pressure containment vessel defining a chamber that encloses a sealed, collapsible, air-less pouch container containing product to be dispensed. A fermentation propulsion system is provided between the inner wall of the chamber and the air-less pouch container. The fermentation propulsion system comprises a quantity of yeast able to generate fermentation gas within the chamber, a quantity of sugar for the yeast to consume to fuel the fermentation process, and a yeast extract to boost fermentation activity. The fermentation gas serves as propellant for dispensing the product by applying pressure to the pouch container. A valve is secured in the opening of the vessel such that the chamber is hermetically sealed, and so that product can be selectively dispensed from the vessel. |
