The stackable carton has two flaps (4) at each end which fit against each other and carry a tenon (10) at the top. A third flap (3) has a cut-out (8) through which the tenons fit and a tab (5) above it which folds down to lock the flap against the other two. When the cartons are stacked the tenons fit into cut-outs (12) in the base of the carton above. An Independent claim is included for a blank from which the carton is produced.
