DEVICE FOR HOLDING AND COOLING AN ELEVATED TEMPERATURE PARISON

摘要

A carrying means for holding and cooling a heated parison therein, has an open forward end for receiving the parison, a closed rearward end, a longitudinal wall between the forward and rearward ends; an internal surface tapers inwardly towards the closed end to define a tube, and cooling means adjacent the longitudinal surface; the internal surface is smaller than the heated parison; the parison also has a corresponding taper so that the cooling means is operative to shrink the parison upon cooling with the parison sliding inside the tube to fit snugly therein; the carrying means further includes suction means adjacent the closed end for maintaining the cooled parison inside the tube.
