Air in the space above the fill level in the neck of a bottle or similar container is displaced before the closure is applied, by injection of a liquid or gaseous medium that causes the product to foam. The system consists of a filling station, a closure station, a star wheel to transfer bottles between the two stations, and a jetting device. The jetting device is mounted to a horizontal holding arm above the transfer star and pivots concentrically around the axis of the transfer star. The conveyor speed is automatically monitored by a tach generator. Its signal activates a servo motor which engages the holding arm and moves it together with the jetting nozzle along the bottle path according to the operating speed. The jetting device is moved closer to the closure station at lower operating speeds while its distance to the closure station is increased during higher speeds. This prevents, without operator involvement, excessive foaming which results in product loss or insufficient foaming which results in high air content of the product.

Apparatus for displacing air from above the fill level in containers such as bottles that are in transit to a container closing unit, comprising: a nozzle located for injecting a jet of a medium into the moving open container to effect said air displacement and movable means to which said nozzle is mounted for being moved selectively closer to and farther from said container closing unit, means for determining the speed at which said containers are transported and drive means controlled by speed determining means to drive said moveable means to locate said nozzle farther from said container closing unit for increasing transport speed and closer to said closing unit for decreasing transport speed so that the elapsed time between injecting said medium and closing of the containers remains substantially constant.
