  • Patent number: 5714111
    Abstract: The invention provides a light weight self-standing blow molded two liter carbonated beverage bottle having a unique petaloid base made from a monobase preform. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet. The monobase preform has a thick reinforcing ring forming portion which remains relatively unstretched during blowing. The reinforcing ring forming portion is thicker than both the strap forming portion, sloping outer wall forming portion and the gate area forming portion of the preform thereby resulting in increased wall thickness reduction, stretching and orientation in those areas during blowing. The reinforcing ring extends circumferentially around the base. By providing such a reinforcing ring, a bottle having a bigger foot radius and/or containing less material usage than prior art containers can be realized.
