An arrangement for automatically controlling the dispensing of a beverage such as a frothy milk shake into an open mouth container such as a translucent paper or styrofoam cup. A dispensing station defines a designated position for the cup to be filled, and a dispensing nozzle is positioned above that designated position. A radiation source is positioned above the cup to direct radiation downwardly through the open mouth thereof such that it passes through the side walls of the cup. A radiation detector is positioned adjacent to an exterior wall of the cup at a vertical position thereon at which the cup holds a “full”dispensed quantity of beverage, such that it produces an output signal indicative of the radiation passing through the wall at the full position. The output signal is compared with a given threshold level, and when it falls therebelow, thereby indicating that the dispensed beverage is at the “full”height, the dispensing operation is terminated.

An arrangement for automatically controlling the dispensing of a beverage into an open mouth translucent container such as a cup, comprising: a. a dispensing station defining a designated position for a cup to be filled, and a dispensing nozzle placed above the designated position for dispensing a beverage into a cup positioned therebeneath; b. a radiation source, positioned above a translucent cup placed in said designation position, for directing radiation downwardly through the open mouth of the cup; c. a radiation detector, positioned adjacent to an exterior wall of a translucent cup in said designated position at a vertical position on the wall at which the cup holds a desired or full dispensed quantity of beverage, for detecting the diffused radiation passing through and diffused by the translucent cup wall at the full position and for producing an output signal indicative thereof; d. means for detecting when said output signal falls below a given threshold level, which indicates the dispensed beverage has filled the cup to the full vertical position; and e. means, responsive to said detecting means, for terminating the dispensing of beverage through said dispensing nozzle.
