Abstract
This relates to an improvement on a recently developed ribbed preform in a champagne type bottle bottom formed therewith including solid internal ribs. In accordance with this invention, the ribs are made hollow or tubular in the preform with the resultant ribs in the bottle bottom also being hollow. The hollow ribs of the preform serve the same purpose as the prior solid ribs in retaining the plastic material of the preform in the bottom area during the bottle formation and the hollow ribs in the resultant bottle also provide the desired added stiffness for preventing bottom eversion.
