A vacuumed formed thin-walled, plastic soft drink dispensing cup is disclosed which has a stacking structure at the lip formed by a short inwardly tapered conical section disposed between a rolled lip at the upper end and an outwardly flaired section at the lower end which forms a downwardly facing annular shoulder having an arcuate cross section adapted to mate with the rolled lip of a like cup in a nested stack.
