Food is packaged under a protective gas in synthetic containers having flexible lids. The sequence of the packaging steps is product filling, lid application, flushing with a protective gas, and sealing the lid. The flushing takes place wherein the lid is affixed to the container edge at at least one location, while one side of the lid is slightly lifted so that the protective gas can be blown therein.

In a procedure for packaging of food under protective gas in synthetic material containers with flexible lids sealed to the rims of the containers where the packaging steps include product filling, protective gas flushing, lid application, and lid sealing; the improvement being in that the packaging steps are performed in the sequence of product filling and then lid application and then flushing with protective gas and then sealing of the lids, the packaging steps being performed to the container while the container is mounted to a movable conveyor, the lid, relative to the movement of the conveyor having upstream and downstream portions and side portions intermediate thereof, the lid application step comprising placing the lid on the container rim so that the lid lies flat on the container, securing the flat-oriented lid to the container at selected spots on the rim thereof intermediate the upstream and downstream portions of the lid, the upstream portion of the lid having a tear-off tongue projecting beyond the container rim, the protective flushing gas step comprising placing a protective flushing gas nozzle beneath the tear-off tongue, raising the nozzle to lift the tear-off and create flow communication between the nozzle and the container head space while the container is stationary, blowing the protective flushing gas through the nozzle and into the head space, utilizing the escaping air from the head space to raise the lid at an unsecured location remote from the tear-off tongue, lowering the nozzle and moving the nozzle sideways out of the path of movement of the container to permit the lid to return to its flat condition, and moving the container to the lid sealing station.
