ABSTRACT:
Apparatus for dispensing a predetermined quantity of product liquid into a series of cartons in sequence is described. The apparatus includes a discharge valve arrangement that directs the liquid obliquely against the wall of the carton to reduce the tendency to produce foam. Also, the apparatus includes a bellows and valve system for controlling the flow of liquid to the discharge valve. A method of operating the system that is described minimizes the liquid pressure differential at the discharge valve when the valve opens.
