Apparatus for sealing closed an integral neck (26) of a previously blow molded bottle (10) comprises an upper neck clamp tooling (62) and a lower neck clamp tooling (60) for engaging and supporting each end of the neck (26), and a heater (80) for raising the temperature of the neck (26) between the clamps (62,60) to permit molding and sealing by a neck sealing tool (64), having recesses (110,112,114) which define at least one cavity when closed. The clamps (62,60) and the neck sealing tool (64) each have drive means for moving them between open and closed positions, and the heater has drive means for moving it towards and away from the neck (26).
