Solche Vorrichtungen sind dazu vorgesehen, aggressive Flüssigkeiten in relativ großen Mengen darin zu verwahren, wodurch das Gewicht erheblich ist und deren Transport mechanisch erfolgen wird. Solche Behälter werden für gewöhnlich auf vorgeformten Paletten aufgestellt, so daß die Gesamtkonstruktion von einem Gabelstapler verfahren werden kann. Um Beschädigung solcher Behälter zu vermeiden, ist es bekannt, um den Behälter eine Schutzvorrichtung anzubringen, die aus einer Kunststoffwand mit offener Oberseite bestehen kann, durch welche Oberseite der Behälter hineingelassen werden kann. Der Inhalt des von der Wand und der Palette begrenzten Raums kann kleiner oder wenigstens genau so groß sein wie der Inhalt des Behälters, so daß im Falle des Ausleckens aus dem Behälter die Flüssigkeit nicht auslaufen kann. In dieser Ausführungsform ist die Oberseite offen und ist der Behälter oben nicht geschützt.Such devices are intended to be aggressive To store liquids in relatively large quantities whereby the weight is significant and their transportation will be done mechanically. Such containers are used for usually placed on preformed pallets so that move the entire construction from a forklift can be. To avoid damaging such containers, it is known to protect the container attach that from a plastic wall with open Top can consist of which top of the Container can be let in. The content of the by the Wall and the range of limited space can be smaller or smaller be at least as large as the content of the container, so that in the event of leakage from the container Liquid cannot leak. In this embodiment the top is open and the container is not on the top protected.
