Abstract

Abstract A flattenable container for the transport and/or storage of small amounts of gas consists of flexible sheet material, e.g., a stack of several layers of metallized plastic foil, closed along the edges by cementing or heat sealing. A portion of the container body is formed into a reduced spout which, after having been cut open at its end, can be temporarily reclosed by folding or rolling up. A small area of the container wall may be reinforced by a self-sealing patch which can be penetrated by a probe for extracting a sample of the stored gas.
