A system for dispensing carbonated beverages into an open container uses a bottom filling technique in which the outlet port of the nozzle is proximate to a bottom of the open container when dispensing is initiated. Specialized valve configurations and operation techniques are implemented in order to achieve enhanced flow characteristics of the carbonated beverage dispensing into the open container. Preferably, the valve head has a distribution surface in which a portion of the distribution surface near a proximal end of the valve head slopes more steeply downward than the portion of the distribution surface that is located towards the distal end of the valve head. With this configuration, the valve head gently redirects the flow trajectory of the carbonated beverage existing the nozzle from a substantially downward trajectory to a more horizontal umbrella like trajectory. It has been found that such a trajectory provides particularly favorable results. In order to maintain a symmetrical umbrella flow pattern, a hub is provided within the flow nozzle to support and align that valve stem.

[ I claim:] [1.]1. A system for dispensing carbonated beverage into an open container comprising:a source of carbonated beverage;a downwardly extending nozzle that receives the carbonated beverage, the nozzle including a flow passageway and an outlet port through which the carbonated beverage dispenses from the nozzle into an open container;a valve mechanism including a valve stem that is located at least in part within the flow passageway of the nozzle, and a valve head having a proximal end connected to the valve stem and a distal end exposed underneath the nozzle, the valve head seating against the nozzle when the valve is closed; andan actuator connected to the valve stem for positioning the valve head relative to the outlet port of the nozzle;wherein the distal end of the valve head has a diameter greater than a diameter of the proximal end of the valve head, and the valve head has a distribution surface in which a portion of the distribution surface near the proximal end of the valve head slopes more steeply downward than a second portion of the distribution surface that is located closer to the distal end of the valve head.
