Abstract
The present invention relates to an improved foldable crate designed to be interchangeably stacked together with solid one-piece crates. The crate has four side walls hinged to each other so that in the folded state of the crate, one pair of side walls become compacted against the other pair in a face-to-face position. Each side wall has a flat top rim, and a bottom rim provided with a series of cantilever support elements integrally formed therewith, projecting into the hollow of the crate and adapted to support the bottom wall of the crate. At least one of the supports of each side wall comprises a depending stop portion underlying and integrally formed with a bottom end-portion of the respective cantilever support elements.
