Abstract
A plastic container comprising a blow-molded plastic bottle with a reinforcing ring encircling the bottle base to reinforce the base against undesirable deformation. The ring encircles the lower end of the bottle base. Pressure within the container expands the base structure outwardly against the ring and creates tension in the ring to maintain the ring in assembly relation with the bottle base in which the ring reinforces the base and acts to maintain the structural integrity of the base. The container is manufactured by inserting the ring into the base portion of the blow-mold such that the ring defines a portion of the blow-mold cavity. A plastic preform is blow-molded outward, into engagement with the ring to secure the ring to the base.
