Abstract: There is provided a stripper assembly (212) for use in a mold stack (202) for forming a preform (210) suitable for blow-molding into a final-shaped container.

Abstract: Disclosed herein are, amongst other things, a molding apparatus with which to mold, in use, a preform of a type for blow molding into a container. The molding apparatus includes a lock ring (104, 204) for use in a first stack portion (108) of a mold stack (120). The lock ring (104, 204) includes a tubular body (150, 250) that is configured to define, amongst other things, a support interface (194) in cooperation, in use, with a split insert (6, 106) of the first stack portion through which a compressive load is transferrable during molding of the preform, wherein the support interface (194) includes a support shelf (154) that is defined, at least in part, on a first major promontory (152, 252) of the tubular body (150, 250).

Abstract: There is disclosed a neck ring (308, 310). The neck ring (308, 310) comprises a molding surface 302 (340) for defining a portion of a molded article to be molded; a first male taper (318) projecting from a body of the neck ring (308, 310); and a second male taper (320) located proximate to an outer lateral periphery of the body of the neck ring (308, 310); wherein the first male taper and the second male taper are configured to cooperate with respective female tapers that are associated with a cavity flange.

Abstract: Disclosed herein is, amongst other things, a molding apparatus that includes a core ring (140, 340, 440, 540, 640, 740) that is configured to seat, in use, around a core insert (120, 320, 420, 620) in a mold stack (116, 216, 316, 416, 516, 616, 716). The core ring (140, 340, 440, 540, 640, 740) is configured to be received, at least in part, within a pocket (152) that is defined within a split insert (150) of the mold stack (116, 216, 316, 416, 516, 616, 716). The core ring (140, 340, 440, 540, 640, 740) is also configured to define at least a portion of a molding cavity (119) having a core ring-to-split insert parting line (180) that is within the pocket (152) of the split insert (150).
