Abstract

A beverage dispensing machine is provided and is of the type having a cup station, a cup holder for holding a plurality of cups, a cup delivery for delivering one of the cups at a time to the cup station, a beverage dispenser for dispensing beverage to the cup station, and controller for controlling operation of the cup delivery and the beverage dispenser. The controller being adapted to initiate a cycle of operation of the machine upon activation of the controller wherein the cup delivery delivers a cup to the cup station from the cup holder and the beverage dispenser dispenses a predetermined quantity of beverage to the cup in the cup station. The improvement comprises a detecting mechanism for engaging and detecting the presence of a container inserted into the cup station prior to activation of the controller. The container detecting mechanism being adapted to modify the cycle of operation of the machine such that upon activation of the controller the cup delivery does not deliver a cup to the cup station and the beverage dispenser delivers a predetermined quantity of beverage to the container inserted in the cup station.

Claims

1. In a beverage dispensing machine of the type having a cup station, means for holding a plurality of cups, means for delivering one of said cups at a time to the cup station, means for dispensing beverage to the cup station, and control means for controlling operation of said cup delivery means and said beverage dispensing means, said control means being adapted to initiate a cycle of operation of the machine upon activation of said control means wherein said cup delivery means delivers a cup to the cup station from said cup holding means and said beverage dispensing means dispenses a predetermined quantity of beverage to the cup in the cup station, wherein the improvement comprises means engageable with a container inserted into the cup station for detecting the presence of the container prior to activation of said control means, said detecting means being operable to modify said cycle of operation of the machine such that upon activation of said control means said cup delivery means does not deliver a cup to said cup station and said beverage dispensing means dispenses said predetermined quantity of beverage to the container inserted in the cup station.

2. A beverage dispensing machine as set forth in claim 1 wherein said detecting means comprises a member engageable with the container and movable upon engagement with the container to an activated position wherein said beverage dispensing means dispenses beverage to the container in the cup station.

3. A beverage dispensing machine as set forth in claim 2 wherein said detecting means further comprises a switch, said member being hingedly connected to a support to be pivoted by engagement with said container in a direction away from said container when said container is placed in said cup station, upon being pivoted, said member releases said switch whereby a signal is sent to said control means for preventing the dispensing of said disposable cup into said cup station.

4. A beverage dispensing machine as set forth in claim 3 wherein said control means comprises a microprocessor located within said vending machine.

5. A beverage dispensing machine as set forth in claim 1 wherein said control means further comprises a currency receiving device, said control means being adapted to activate said cycle of operation of the machine upon insertion of a predetermined amount of currency therein, the currency receiving device being adapted to either refund a portion of said predetermined amount of currency upon detection by said detecting means of a container inserted into the cup station, or lower said predetermined amount of currency.

6. In a beverage dispensing machine of the type having a cup station, means for holding a plurality of cups, means for delivering one of said cups at a time to the cup station, means for dispensing beverage to the cup station, and control means for controlling operation of said cup delivery means and said beverage dispensing means, said control means being adapted to initiate a cycle of operation of the machine upon activation of said control means wherein said cup delivery means delivers a cup to the cup station from said cup holding means and said beverage dispensing means dispenses a predetermined quantity of beverage to the cup in the cup station, wherein the improvement comprises means for engaging and detecting the presence of a container inserted into the cup station prior to activation of said control means, said container engagement and detecting means being adapted to modify said cycle of operation of the machine such that upon activation of said control means said cup delivery means does not deliver a cup to said cup station and said beverage dispensing means deliver said predetermined quantity of beverage to the container inserted in the cup station, and a means for remitting a discount wherein said control means includes a currency receiving device, said control means being adapted to activate said cycle of operation of the machine upon insertion of a predetermined amount of currency therein, the currency receiving device being adapted to either refund a portion of said predetermined amount of currency upon detection by said engaging and detecting means of a container inserted into the cup station, or lower said predetermined amount of currency.

7. A beverage dispensing machine as set forth in claim 6 wherein said engaging and detecting means comprises a member engageable with the container and movable upon engagement with the container to an activated position wherein said beverage dispensing means dispenses beverage to the container in the cup station.

8. A beverage dispensing machine as set forth in claim 7 wherein said engagement member includes a pivotable member and a switch, said member being hingedly connected to a support to be pivoted by engagement with said container in a direction away from said container when said container is placed in said cup station, upon being pivoted, said member releases said switch whereby a signal is sent to said control means for preventing the dispensing of said disposable cup into said cup station.

9. A beverage dispensing machine as set forth in claim 8 wherein said control means includes a microprocessor located within said vending machine, whereby said microprocessor instructs said cup supply to not drop said disposable cup to said cup station when a container is placed in said cup station.
