Abstract: After a container is placed on a rest base beneath a beverage dispensing section where a dispensing outlet is provided, a dispensing button is depressed and a stepping motor constituting a base tilting drive device is driven for a predetermined time period to cause a linear head to be extended so that the rest base and hence a container is tilted as one unit. A dispensing valve drive device is operated to open a dispensing valve and dispense a bubbling beverage along an inner wall of the container, while suppressing any excessive formation of bubbles. When a bubble surface or liquid level of the beverage dispensed into the container rises to a predetermined level, the stepping motor is reversely driven to bring the container to an erect state. When the container becomes full with the beverage, the dispensing valve is closed, stopping the dispensing of the beverage.

The weights are determined upstream of the filling station. The containers are filled according to a set point, then the containers are moved to a gross weighing station where they are weighted full and tare weight is deducted therefrom.

Abstract: A supply tank having a plurality of dip tubes extending therein is provided. One dip tube is provided for each storage tank that is to be filled by the supply tank. The dip tubes are of different lengths, and their lengths are related to the amount of syrup each dip tube is to deliver. A source of compressed gas communicates with the tank to force the syrup in the tank up the desired dip tube and into the delivery line connected to the onsite syrup storage tank. When the level of syrup in the tank falls below the end of the dip tube through which delivery is being made, the flow of fluid therethrough stops, and the compressed gas forces all of the syrup in the delivery line into the storage tank. By controlling the length of the dip tubes the amount of syrup delivered can be controlled.

The vacuum is created in the supply line by an automatically operating valve that closes the supply line when the tank is empty. A cleaning system is also provided that can be connected to the vent of the empty tank to clean it before it is refilled with syrup. A drain line cooperates with the valve to maintain the valve in its open position and allow the cleaning fluid to drain from the tank.
