Abstract

A safety container for dispensing highly flammable liquids is described, which comprises flexible compressible container walls and a safety valve which is designed as a membrane-controlled cone valve, closable by a cap. The membrane exhibits a central hole bounded by a sealing edge, through which a valve cone is inserted and contacted by the sealing edge. The cone valve is operated by pressing the flexible container walls together and thereby reducing the interior space of the container and raising the internal pressure.
