In a post-mix beverage dispenser including a water supply assembly, a concentrate supply assembly and a mixing assembly for mixing water from the water supply assembly and concentrate from the concentrate supply assembly together to form the post-mix beverage, the improvement comprising: (a) peristoltic pump means having a rotary pumping member; (b) the concentrate supply assembly being disposable and including, 1. a disposable concentrate container; and 2. disposable flexible conduit means connecting said concentrate container to said mixing assembly and being disposed in operative engagement with said rotary pump member to cause concentrate in the container to be pumped through the conduit means to the mixing assembly; wherein the concentrate container has an external surface portion with a complementary shape to an external surface of the rotary member of the peristoltic pump, and the conduit means is operatively engaged between said surface portion and said external surface, said container including a rigid outer shell, a portion of which forms said surface portion, and a sealed collapsible bag within said rigid outer shell, said bag having a discharge opening in fluid communication with said conduit means through a valve means, said surface portion with the complementary shape being disposed on a bottom wall of the rigid shell and said valve means is disposed in said bottom wall adjacent said surface portion with an actuator stem extending from said bottom into contact with a stationary support surface, whereby the weight of said container causes the support surface to depress said stem to open said valve means when said surface portion with said complementary shape operatively engages the conduit means.
