Abstract
A liquid dispensing system includes a selectively adjustable material control device and a sealing device within a dispensing device. The sealing device is in communication with a switching device to move the sealing device between a first position and a second position. The first position of the sealing device allows the material control device to draw a volume of material into the dispensing device and the second position of the sealing device allows the material control device to force the volume of material to dispense from the dispensing device.
