Abstract: The invention relates to a stackable transport container, particularly for fruits, vegetables or dairy products, in which a one-piece blank has a quadrangular bottom and four walls rising upwardly and slanting slightly outwardly therefrom, which walls delimit an upwardly widening container filling space. In the four corners thereof there are arranged upright stacking supports formed by parts of the blank and serving for stiffening the container. The upper edges of the stacking supports are arranged below the upper edges of the adjacent container side wall sections so that during the stacking of two nested containers, the bottom of the upper container rests on the stacking supports of the lower container, the upper edges of the container side walls of the lower container securing the upper container against lateral displacement.
