Abstract: An independent transport container or a transport container mounted on a vehicle such as a truck, trailer or railway car, includes a generally rectangular-shaped horizontal loading surface whereby at least one lateral surface is fitted with tarpaulin side walls that are mounted in such a way that they can slide in a longitudinal direction on an upper rail. The tarpaulin side walls are hooked to a set of rigid louvers which can be folded like an accordion, whereby the upper end of the louvers slides on an upper rail with the aid of carriages which are provided with casters and the lower end slides on a lower rail, bearing the upper rail, with the aid of lower chariots which are provided with rollers.
