A nestable beverage cup is preferably formed of two tapered sections. A lower section is sized to fit a cup holder such as used in a vehicle, while an upper section which is not held in the cup holder is provided with a larger diameter than the lower section, and is more broadly tapered to hold a greater volume of fluid. The lower section has a flattened rim which is ultrasonically sealed to the bottom of the upper section. A recessed bottom of the upper section provides an air gap which will insulate the user from the surface of the lower section. The two stage cup contemplates designs with various sidewalls, angles, shapes and raw materials.
