reusable container for safe and environmentally sound storage, transport and disposal of fluids

摘要

Container for a fluid, in particular transport container and storage container, with filling and extraction openings and, in the container interior, an expandable foil structure which can be filled internally with a fluid and which closes off and isolates the fluid filling both from the container inner walls and from the inner surfaces of the filling and extraction openings and only temporarily adheres to these surfaces but in the emptied state can be pulled out through at least one of the two openings. After insertion into the container, the two ends of the foil structure form simultaneously a seal for interchangeable component parts to be inserted for sealing, filling, stirring, extraction, emptying, dosing, measuring, regulating, mixing, homogenising, emulsifying, dispersing, dissolving and the like, so that contact between fluid and container material is prevented in every operating situation (Fig. 1). In addition to a foil structure suitable for this for insertion into the container and filling, a method of extracting the fluid or of emptying the filled container and a method of filling the container system with a fluid are also indicated.
