LIQUID DISPENSER FOR USE WITH CONTAINERS

摘要

A beverage dispensing system (10) that fits inside a completely filled standard beverage container (80) with minimal displacement of the beverage level. A fastener (32) attaches the dispenser to the spout portion of the container. An inflatable bladder (12) pressurizes the beverage at all times. Pressure tubing (50) connects the bladder to a pressure sensor and a pressure source. A pin (34) controls the flow of gas through the pressure tubing. Gas can flow into the bladder when the dispenser is attached to the container. Gas is purged out of the bladder and pressure tubing before the dispenser is removed from the container. A draw tube (20) conducts the beverage under pressure from the container, through beverage exit tubing (60), out to be dispensed.
