ABSTRACT:
A blow molded PET container is disclosed having a ribbed base structure to provide stiffening of the base structure to prevent undesirable deformation. The container is designed to accommodate moderate internal pressurization of 30 to 50 psi to provide packaging for products which must be contained in a pressurized package but not pressurized to the extent of a carbonated beverage. The reinforcing ribs required in the base structure are thus not as deep as found in ribbed base structures for carbonated beverage containers resulting in less plastic resin required to produce the container. As a result, the container fills a void in the packaging industry between containers for non-pressurized products and containers for highly pressurized carbonated beverages.
