Embodiments of the present invention are directed to a dispensing apparatus for dispensing a flowable product. In one embodiment, the apparatus comprises a dispenser housing having a product outlet extending from the dispenser housing to dispense the flowable product from the product package; and a bellows pump having a pump inlet, a pump outlet, and bellows disposed between the pump inlet and the pump outlet. The pump outlet is coupled to the product outlet of the dispenser housing. The pump inlet is configured to be coupled to the product package outlet of the product package. An actuation lever is coupled with the bellows pump. The actuation lever protrudes to an exterior of the dispensing housing and being movable to compress the bellows of the bellows pump in a compressed position and expand the bellows of the bellows pump in an extended position to pump the product from the product package to the product outlet. A resilient member is connected with the actuation lever to bias the actuation lever to one of the compressed position and the extended position.

The apparatus of claim 2 wherein the resilient member comprises a return spring connected between the pump mounting bracket and the actuation lever. 8. The apparatus of claim 1 wherein the bellow pump is disposable. 9. The apparatus of claim 1 further comprising: a cooling unit configured to generate a cool gas in the dispenser housing to cool the product package disposed in the dispenser housing; and a product flow line disposed in the dispenser housing and configured to be coupled between the product package outlet and the pump inlet to dispense the flowable product from the product package. 10. The apparatus of claim 9 further comprising a flow channel guide disposed in the dispenser housing to guide the cool gas to flow from a first region in the dispenser housing near the cooling unit to a second region in the dispenser housing near the product outlet along at least a portion of an external surface of the product flow line, the flow channel guide including a return passage to guide the cool gas away from the product flow line back to the first region near the cooling unit. 11. The apparatus of claim 10 further comprising a flow control device configured to drive the cool gas from the first region in the dispenser housing near the cooling unit to the second region near the product outlet and through the return passage back to the first region. 12. An apparatus for dispensing a flowable product from a product package through a product package outlet, the apparatus comprising: a dispenser housing having a product outlet extending from the dispenser housing to dispense the flowable product from the product package; a bellows pump having a pump inlet, a pump outlet, and bellows disposed between the pump inlet and the pump outlet, the pump outlet being coupled to the product outlet of the dispenser housing, the pump inlet configured to be coupled to the product package outlet of the product package; a pump mounting bracket attached to the dispenser housing, the bellows pump being supported by the pump mounting bracket; and means coupled with the bellows pump and the pump mounting bracket for moving the bellows of the bellows pump between a compressed position and an extended position to pump the product from the product package to the product outlet; wherein the pump mounting bracket is attached to a movable portion of the dispenser housing which is movable between a closed position and an open position via a hinge to expose the pump mounting bracket and bellows pump in the open position and allow the pump mounting bracket and bellows pump to be accessed from outside the dispenser housing, the dispenser housing enclosing the pump mounting bracket and bellows pump with the movable portion of the dispenser housing in the closed position. 13. The apparatus of claim 12 further comprising resilient means for biasing the bellows pump to the extended position. 14. The apparatus of claim 12 wherein the movable portion of the dispenser housing is disposed on a side with the product outlet oriented downward below the bellows pump, and wherein the hinge is disposed below the bellows pump. 15. The apparatus of claim 14 wherein the dispenser housing includes a lid to support the movable portion of the dispenser housing in the closed position. 16. The apparatus of claim 12 further comprising: a cooling unit configured to generate a cool gas in the dispenser housing to cool the product package disposed in the dispenser housing; and a product flow line disposed in the dispenser housing and configured to be coupled between the product package outlet and the pump inlet to dispense the flowable product from the product package. 17.
