One embodiment of such system comprises an apparatus for dispensing a liquid, which includes dispensing means for dispensing liquid, and supply means for supplying the liquid to be dispensed. The supply means includes a hermetically-sealed, flexible bladder in which the liquid is disposed as well as a container for containing the flexible bladder. A hermetically-sealed coupling extends from the flexible bladder through the container and provides a hermetically--sealed conduit through which the liquid flows from the bladder. Elevating means are provided for elevating the supply means above the dispensing means. Supporting means are provided for supporting the hermetically-sealed coupling at the elevating means. First conveying means having a first flow path are connected to the supply means and extend to the dispensing means. Second conveying means having a second flow path which is narrower than the first flow path are connected thereto for conveying the flow of the liquid from the first flow path to the dispensing means. Air supply means are connected to the dispensing means. Finally, first control are means operatively associated with the dispensing means to control the dispensing of boththe liquid and the air supply in a predetermined pattern.
