ABSTRACT:
A base stand for use with a plastic bottle having a hemispherical bottom includes a thin-wall cylindrical sheath portion and a thin toroidal-shaped base portion having a lowermost rim defining a seating ring. The sheath portion engages the side wall of the bottle and the toroidal-shaped base wall contacts and supports the bottle hemispherical bottom. The base stand is formed by bringing organic plastic material to orientation temperature and drawing the heated plastic material over a conical mandril to form a thin-wall tube. The resulting thin-wall tube is pressed against a forming plate to roll one end of the thin-wall tube in on itself to form a toroid.
