Claims
- 1. An apparatus for dispensing metered quantities of beverage concentrate for mixing with a diluent to produce a post-mix beverage comprising:
- a storage tank for containing the beverage concentrate, said storage tank having a discharge opening through which the concentrate may flow by gravity;
- positive displacement pump means integrally connected with the storage tank at the discharge opening thereof for withdrawing concentrate through the discharge opening from the storage tank by suction into a housing of the pump means, and discharging metered quantities of concentrate from said pump housing through an outlet thereof for mixing with the diluent in response to reciprocating movement of an actuator of said pump means;
- a cabinet for housing said storage tank for operative association with a supply of diluent, said cabinet including a coupling member therein for engaging the pump housing and rigidly supporting the storage tank; and
- drive means in said cabinet for engaging the actuator of the pump means while the storage tank is rigidly supported and imparting said reciprocating movement thereto to thereby dispense concentrate from the outlet of the pump housing, said drive means including,
- a lever arm pivotally mounted in said cabinet and having a first forked end engaging the actuator of the pump means for imparting said reciprocating movement, said lever arm having a second forked end,
- a rotary cam engaged within the second forked end for pivoting said lever arm as said cam rotates to reciprocate said actuator, sand
- a motor for rotating said cam.
- 2. The apparatus of claim 1 wherein said storage tank comprises a substantially rigid outer container and a flexible bag therein, said flexible bag containing said concentrate, said discharge opening being formed through aligned openings in both said outer container and flexible bag.
- 3. The apparatus of claim 2 wherein said positive displacement pump means is a piston pump.
- 4. The apparatus of claim 2 wherein the integral connection between the pump means and storage tank is a flexible membrane movable between inboard and outboard positions of a wall of the storage tank in which said discharge opening is disposed such that said pump means is also movable to inboard and outboard positions with respect to the wall of the storage tank.
- 5. The apparatus of claim 4 wherein said positive displacement pump means is a piston pump.
- 6. The apparatus of claim 1 wherein the integral connection between the pump means and storage tank is a flexible membrane movable between inboard and outboard positions of a wall of the storage tank in which said discharge opening is disposed such that said pump means is also movable to inboard and outboard positions with respect to the wall of the storage tank.
- 7. The apparatus of claim 6 wherein said positive displacement pump means is a piston pump.
- 8. The apparatus of claim 1 wherein said positive displacement pump means is a piston pump.
