A telescoping filling head comprising a driving portion, a nozzle block portion and a two-stage telescoping nozzle, the innermost portion of the nozzle having positionable apertures. A telescoping filling head can be retrofitted on an existing filling device, or can be incorporated in a newly manufactured filling device. The telescoping action permits a longer nozzle to be used in any given space, because the two portions which extend to create a relatively long filling nozzle retract within a relatively short outer nozzle. The longer nozzle increases the rate at which foaming liquids can be introduced into a container. The positionable apertures can also direct the flow of the liquid at the shoulders of the bottle, further increasing the rate at which foaming liquids can be introduced into a container.
