A dispenser for liquid consumables locates a store of the particular
liquid at a location remote from the dispensing location. The dispensing
location is typically located above a counter and may include a
relatively narrow stem that brings a flexible liquid delivery tube up to
a valve. Valuable counter space is conserved. One or more disposable,
flexible and collapsible bags contain the store of liquid and
communicates with the dispensing location via the liquid delivery tube.
Confined in contact with each flexible bag is an inflatable bladder to
which compressed air is routed. Liquid is dispensed each time the valve
opens. When exhausted the flexible bag is replaced. Safety interlock
switches vent the inflatable bladder to prevent its expanding explosively
upon opening of the location where the liquid containing bag will replace
the empty. Where the liquid needs temperature control, temperature
control means are provided where the liquid is stored. Air movement from
that location into the stem to a dispensing fountainhead controls the
temperature of the liquid in the delivery tube. In the dispensing of
dairy product, as in cream for coffee, temperature control is
refrigeration. The dairy product is cooled over its entire route from the
flexible bag to the fountainhead. The location of the collapsible,
flexible bag and expansible bladder may be directly below the stem and
fountainhead in a cabinet, and the entire unit may be movable from one
location to another. When consistency of liquid amount dispensed is
needed, a dosing valve meters out a measured amount.
