<p>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 (8) that directs the liquid obliquely against the wall of the carton to reduce the tendency to produce foam. Also, the apparatus includes bellows and a valve system (22) for controlling the flow of liquid to the discharge valve (8). A method of operating the system that is described minimizes the liquid pressure differential at the discharge valve when the valve opens.</p> |
