A hot fillable container includes a bottom and a sidewall connected with the bottom so as to define an internal space. The sidewall is further shaped so as to define in transverse cross-section a first convex sidewall label area having a first convexly curved outer surface having a first curvature and a second convex sidewall area having a second convexly curved outer surface having a second curvature. The label area is of the type that has no horizontal reinforcing ribs. The sidewall is constructed and arranged so that deformation of the sidewall in response to a partial vacuum condition within the internal space after a hot fill process will result in a decrease of the first curvature and an increase of the second curvature. This deformation is effected without any denting of the sidewall.
