Abstract

Substances inside a container are protected from undesirable gases e.g. air by a barrier. An extra opening above the filling level in the container has an air-tight bag fixed on; at the latest when emptying the container this bag is inserted into the container so that its fills with air and replaces the volume emptied from the container. The bag is a thin elastic thermoplastic film. The method is suitable for protecting e.g. powders or liquids such as wine, juices, beer etc. from oxidn. where these substances are emptied from the bottom of the container; it is not affected by the filling level in the container.
