Abstract
A vehicle for the selective transport of a piece load or a bulk load has a container including a bottom constituting, at least in part, a funnel having a discharge opening, a top closure arranged above the bottom and collapsible side walls attached to the bottom and the top closure. The side walls are formed of a plurality of relatively rigid side wall elements having, in a lowered position of the top closure, a collapsed state in which they are stacked with respect to one another between the top closure and the bottom. In the collapsed state of the side walls the upper face of the top closure serves as a loading platform for a piece load. The side walls further have, in a raised position of the top closure, an erected state in which the side wall elements together contiguously form sealed side walls.
