A stackable tray having upstanding projections on its walls and apertures in its bottom, so that a stack of the trays can be stabilized by inter-engagement of the projections and apertures. The projections are provided in at least two corners, and each projection extends laterally around the corner. The angled form of the projection, particularly when made from foldable sheet material, strengthens it against lateral deformation in a stack of filled trays. When used for containing meals or refreshments at least a part of one wall of each tray may be lower than the other walls.
