The carton in the shape of a triangular prism has three walls (14, 16, 18) connected by folds. Two of these (14, 16) have locking tabs (46, 48) at each end with notches (58, 64) on opposite sides. The third side (18) has tabs (50) at each end which have symmetrically spaced projections which interlock with the notches to fasten the carton together.
