Claim 10:
11. The mold stack according to claim 10, wherein
the first ellipse defining the first elliptical curvature has a first radius IR1 being parallel to the vertical center axis of the mold stack and a second radius IR2 being perpendicular to the vertical center axis of the mold stack, the first radius IR1 being greater than both the second radius IR2 and a radius of the first cavity defining portion of the core insert defining at least in part a cylindrical inner face of the body of the preform, and
the second ellipse defining the second elliptical curvature has a first radius OR1 being parallel to the vertical center axis of the mold stack and a second radius OR2 being perpendicular to the vertical center axis of the mold stack, the first radius OR1 being greater than both the second radius OR2 and a radius of an inner surface of the cavity insert defining a cylindrical outer face of the body of the preform.
