Claim:
1. A liquid mixing and dispensing system comprising: a housing enclosing a chamber; multiple containers in said chamber; a flexible bag in each of said containers; a plurality of first liquids in said flexible bags; connecting conduits leading from said flexible bags to a discharge conduit; check valves in said connecting conduits for preventing reverse liquid flow from said supply conduit into said flexible bags; and a constant flow valve through which a pressurized second liquid is delivered via a supply conduit to said containers and to said discharge conduit, said constant flow valve being normally closed, being opened in response to second liquid pressures above a lower threshold level, being operative at second liquid pressures between said lower threshold level and an upper threshold level to deliver said second liquid at a substantially constant pressure, and being closed in response to second liquid pressures above said upper threshold level, said pressurized second liquid serving to collapse said flexible bags and eject said first liquids from said flexible bags and via said connecting conduits into said discharge conduit for mixture with said first liquids.
