Abstract
There is disclosed a method for injecting liquid into a container that senses the location of the bottom of the container, not simply by the force of "running into" the container, but rather, by first sealing the dispensing orifice against the bottom of the container, pressuring the liquid in the orifice and then backing off the orifice until release of liquid out the orifice is sensed.
