Abstract
Two-piece cups formed, e.g., from a thermoformable plastics material, include a bottom wall disc which is bonded to an inwardly turned annular bottom flange of the side wall by an upwardly and inwardly sloped transition wall. The transition wall allows the bottom wall disc to be bonded to the sidewall flange in such a manner that the annular bottom edge is substantially unaffected by the heat and pressures during the bonding process. The bottom wall disc may be in the form of multiple concentrically disposed, annular bottom wall segments which are connected to one another by respective ones of a plurality of transition walls.
