ABSTRACT:
Open-top cup-shaped containers which contain supplies of perishable foodstuffs are transported seriatim past a station where they receive jets of preserving gas which expels air from the unfilled portions of containers, and the containers are then sealed by application of metallic or plastic foils which are bonded or otherwise sealingly secured to washer-like rims surrounding the open tops of the containers. The foils can be partially applied ahead of the gas introducing station and are thereupon finally sealed in at least one second step, particularly in a chamber wherein the containers advance stepwise downstream of the gas introducing station and wherein the temperature and/or pressure is maintained at a preselected value to promote expulsion of air from the containers prior to the final sealing step.
