Abstract

A method and apparatus for supplying a gas or gas mixture to the inside of partly formed packages which are ready-to-fill, before a subsequent filling and sealing of the packages in a filling machine. The method involves supplying the gas or gas mixture at any given moment as a flow which is radially outwardly and inwardly defined in relation to the inner wall of the package, with the flow being angled with respect to the geometric major longitudinal axis of the package which intersects its opening so that the flow, since it is defined by the inner wall of the package, is positively controlled for the formation of a helical flow vortex.
