Abstract:
A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform. The method includes creating a dispensing opening through the closed end of the container body.

Abstract:
A plastic container comprises a lower base-forming portion that includes a plurality of circumferentially-spaced, generally spherically-shaped segments and a plurality of intervening, circumferentially-spaced, totally convex, hollow foot-forming portions that extend radially from the central bottom portion and downwardly from the spherically-shaped segments to form a clearance for the central bottom portion. The clearance-forming portion of each foot-forming bottom portion includes a compound curved offset formed with opposing radii of curvature of a substantial fraction of an inch, the compound curved offset curving downwardly and outwardly about a center of curvature below the bottom-forming portion before curving about a center of curvature above the bottom-forming portion. Each bottom clearance-forming portion further includes a spherical surface curving downwardly and outwardly from the central bottom portion and member into the compound curved offset and a lowermost substantially planar portion extending downwardly and outwardly from the compound curved offset for formation of one of the supporting feel.

A blow mold system including a mold body and a base portion. The mold body includes a central bore extending from a first end of the mold body to a second end of the mold body along a longitudinal axis. The first end is configured to receive a mold preform. The base portion includes a recess, and the base portion is arranged at the second end of the mold body such that the central bore and recess define a blow mold cavity in which a container may be formed from the mold preform. In embodiments, the blow mold system has at least two interchangeable base portions that allow for containers with differently-sized or differently-shaped necks to be formed.
