The apparatus includes a housing having a covered chamber and open bottom, with a diffuser screen and pairs of baffle arrangements therein for directing the nitrogen downwardly and forwardly into the leading carton of an aligned pair of filled but open-topped cartons, and downwardly and rearwardly into the trailing carton of the pair prior to sealing the end closures thereof.
