Abstract

Parent patent described tools for blow moulding containers fitted with a tamperproof stopper, where relative movement between the mould(s) and the blowing mandrel meant that the mandrel did not always impinge concentrically with the parison, thus causing excessive tool wear. Addn. describes alternative designs in which the parison neck may be defined in a split collar located by external radial springs which allow the parison mouth to align with the incoming mandrel. Alternatively, the mandrel may carry a spring loaded floating collar which can pick up on the parison mouth to align it with the mandrel.
