A container formed from a blank to define indexing longer walls having an inward incline but a double thickness provided by a fold at the tops thereof so that the indexing projections (12) are receivable within corresponding openings in the base (2) of a corresponding stacked container. Each part of the indexing walls has an extension (16, 18) such that at each end thereof one extension (18) attaches to the outside of an end wall while the other (16) attaches to the inside of an end wall. Preferably, the extension (16) attaches to the inside of the end wall through a pair of parallel vertical folds (22) providing a support at least in part for the weight of a corresponding stacked container. Each indexing wall has a cut-out (28) associated with the opening in the base (2) to facilitate placing the extension (12) into the opening of the base (2).
