Abstract

The invention relates to a blow mold for molding a heated preform to form a container having an internally domed base, the blow mold defining a cavity including a base forming portion, which has a central substantially hemispherical dome portion and, at the center of the dome portion, a gradually sloping inverted portion with a central substantially axial recess. The latter matches an intended shape of an original depending axial portion on an intended preform.
