A cup-shaped body having an axis of longitudinal extension and defining a mouth and a longitudinally-extended body which is closed at the opposite end from the mouth; the longitudinally-extended body has a conical or frustum-like extension with a diameter that increases progressively from the opposite end toward the mouth, the cup-shaped body having a height extension measured between the mouth and the opposite end, while the mouth has a circular shape with a diameter.

The cup-shaped body has the following features: the ratio between the height extension and diameter is between 0.35 and 1.65; and the ratio between the diameter, measured in millimeters, and the average taper (Cmedia) between the taper of the external surface of the longitudinally-extended body and the taper of the internal surface of the longitudinally-extended body, diameter/Cmedia, is between 0.5 and 1.

A plastic container includes a hollow body portion including a lower supporting base portion; a sidewall portion extending upwardly from the base portion; and a neck portion extending upwardly from the sidewall portion. The neck portion includes a support flange having an upper and lower surface, at least one thread, and a dispensing opening at the top of the neck portion. In embodiments, a closure may be provided to form an assembly. A preform and method for making a container are also disclosed.
