Abstract

The stub necks for the closure of hollow vessels blow moulded from an extruded thermoplastic tube, such as army jerrycans, are reinforced by an inner wall enclosing a metal stiffening ring. The pneumatic probe to blow the tube passes through two balloons, both being inflatable from outside, and smaller when deflated than the inside diameter of the finished vessel neck. The first balloon carries a metal ring positioned so as to be bonded into the neck when the moulds close. When the vessel is formed in the mould, two clamping plates press the overhanging plastic against the blow pipe, and withdraw permitting a metal lead in front of the second balloon, to ride upwards pushing the plastic tube into the interior of the vessel until a stop on the probe reaches the vessel neck. The second balloon is then expanded to tear off the tube from the probe and weld it to be inner wall of the vessel.
