A stackable container comprising:

• a rectangular base,
• two longer walls connected in hinged fashion to the base, and
• two shorter walls connected in hinged fashion to the base,
• the longer and shorter walls being pivotable between an erected useful position and an empty position folded in towards the base,
• at least one of the walls having a recess defined by two lateral edges which are spaced apart and a lower edge of said respective wall, the recess being configured to be covered for a transport of transport items housed in the container and configured to be uncovered for a presentation and removal of the transport items,
• wherein a wall rail that runs horizontally parallel to the base is guided in a vertically displaceable fashion at its ends in sliding guides that run along the lateral edges of the recess, between a raised position where the recess is covered and a lowered position where the recess is uncovered, and
• wherein between the wall rail and the lower edge of the recess there are situated at least two wall braces that, in the raised position of the wall rail, run obliquely to the vertical direction away from one another and are spaced apart from one another in a longitudinal direction of the wall, wherein each of the at least two braces includes an upper end and a lower end, such that the upper end of each brace is connected in a hinged manner to the wall rail.
