Abstract
A system for the preparation of a liquid product has a dispensing apparatus and a disposable cartridge. The cartridge includes a reservoir filled with a single serve portion of a liquid ingredient to be combined with a base liquid, one or more dispensing passages, and a sealing film that covers the reservoir. The apparatus has a pressurization dome member with a peripheral gas seal adapted to sealingly engage the cartridge around a location where one or more openings are created in the sealing film. A pressurized gas source is connected to the dome member. The apparatus feeds pressurized gas beneath the dome member, to allow the liquid ingredient to be pressurized via the one or more openings in the sealing film, to assist dispensing of the liquid ingredient from the reservoir via the one or more dispensing passages.
