  • Patent number: 7780025
    Abstract: A base for a plastic container defining a central longitudinal axis. The base includes an annular standing ring portion defining a standing surface. The base includes a substantially cylindrical ring portion extending in a direction substantially perpendicular to the standing surface. The base further includes a substantially concave dome portion extending inwardly from the substantially cylindrical ring portion to the longitudinal axis. The concave dome portion of the base includes a first plurality of substantially triangular panels circumferentially spaced around the longitudinal axis, and a second plurality of substantially triangular panels circumferentially spaced around the longitudinal axis. At least a portion of each of the second plurality of substantially triangular panels is circumferentially and longitudinally offset from the first plurality of substantially triangular panels. A container preform and method of hot filling a plastic container are also disclosed.

  • Patent number: 5928581
    Abstract: In a blow-molding system in which a parison programmer is coupled to orifice tooling in an extrusion die head for controlling wall thickness of an extruded parison fed to a blow-molding apparatus, a method of synchronizing operation of the parison programmer contemplates placement of observable indicia on the parison after the parison exits the die head. This indicia placement preferably is carried out under control of the parison programmer to place the indicia at a predetermined position along the parison profile, such that mis-positioning of the indicia indicates absence of phase synchronization of the parison programmer. The indicia is then observed on a molded article to determine phasing of the parison programmer relative to the molding apparatus, and operation of the parison programmer is adjusted to correct any mis-positioning.
