A method for inspecting the material distribution of a sequence of stretch blow molded containers or other articles in a continuous production process, by providing injection molded parisons, each parison having at least one indicator, typically two or more indicators, for detecting material distribution at a predetermined position along the axial extent of the parison. Each of the parisons is subjected to a heating stage in the continuous production process, generally by exposure to infrared heating. Each heated parison is then subjected to a blow molding process, which can be a stretch blow molding process, so that each material distribution indicator is transformed to a corresponding position along the axial extent of the blow molded article. A detector is positioned to detect the location of each indicator on each blow molded article from a given mold in the production process. A computation is then made to determine for each blow molded article a material distribution outcome or profile based on the detected locations of each indicator.

A non-destructive, direct method and apparatus for producing stretch blow molded articles having at least one physical dimension within a preselected range. The apparatus includes an injection mold defining an injection mold interior surface having a first differentially dimensioned portion disposed at a preselected location thereon and capable of producing a parison having a parison exterior surface including a first marker formed by contact with the first differentially dimensioned portion, and a stretch blow mold defining a stretch blow mold interior surface having a second differentially dimensioned portion disposed at a predetermined location thereon and capable of producing the article from the parison including a second marker formed by contact with the second differentially dimensioned portion. Relative position of the first marker with respect to the second marker indicates whether a dimension is within a preselected range. The method includes injection molding a parison so that a parison exterior surface includes a first marker disposed at a preselected position thereon and formed by contact with a first differentially dimensioned portion disposed at a preselected location on an injection mold interior surface, and stretch blow molding an article from the parison so that an article exterior surface includes a second marker disposed at a predetermined position thereon and formed by contact with a second differentially dimensioned portion disposed at a predetermined location on a stretch blow mold interior surface.

A plastic container comprises a lower base forming portion that includes a plurality of circumferentially spaced downwardly convex segments (126) and a plurality of intervening, circumferentially spaced, totally convex, hollow foot forming portions (121) that extend radially from the central bottom portion (120) and downwardly from the downwardly convex segments to form a clearance (124) for the central bottom portion. The downwardly convex segments have smoothly curved cross sections, in radially extending planes through their central regions and coplanar with the container's longitudinal axis (120a). The clearance forming portion (123) of each foot forming portion includes a compound curved offset formed with opposing radii of curvature lying in a range of about 15% to over about 30% of foot contact diameter, the compound curved offset curving downwardly and outwardly about a center of curvature (131) below the bottom forming portion before curving about a center of curvature (130) above the bottom forming portion.
