Abstract

The plastic nozzle for a blow moulding/core-blowing jet has a large central filling hole, an outer portion adjacent to the blowing head, and an inner conical part to fit the filling hole of the mould/box, this cone joins the outer portion via a circumferential shoulder for elastic support by a mating shoulder on the mould/box, thus ensuring a good seal when positioned horizontally on the mould/box. Ensures good resilient sealing fit to each blowing opening.
