Abstract
A system for introducing liquified gas into filled containers in a continuous container fill line (10), wherein, the dosage of liquified gas dispensed into each container is calibrated to the individual container's particular head-space volume. The system (10) includes measuring the head-space volume of each filled container in-line and communicating that measurement to a controller (28) which can adjust the dosage of liquified gas to be dispensed to each individual container. The system also provides for measuring the internal pressure of each container after sealing, which measurement is also communicated to the controller so that the controller can make additional dosage corrections and can direct the ejectment of improperly pressurized containers.
