Containers made of plastic materials, suitable for the storage and transportation of liquid particularly in the nourishment domain, and which consist of the containers and closures. The containers serve also as universal building elements, which are connected by coupling elements, i.e. closures, into new three-dimensional structures. In such a way, the containers themselves can be kept, collected and, for example, used for playing. They will not be disposed daily into refuse, but will be disposed of more rarely in order to enable their recycling.
