Abstract

An apparatus and a method of supplying gas or a gas mixture to the inside of partly formed packages in a filling machine before a subsequent filling and sealing of the packages involves supplying the gas or gas mixture as at least one flow into the package via an opening in the package. The supply is made such that the at least one flow flows into the package to the inner region of the package and thereafter returns back through the opening. The method also involves temporarily catching the return flow from the package in a delimited space outside the opening, and directing the return flow out from the space in such a way that a substantially vertical flow along the outer envelope surface of the package is formed.
