Abstract

1390234 Injection blow-moulding WHEELING STAMPING CO 30 March 1972 [9 June 1971] 15053/72 Heading B5A Manually deformable tubes, e.g. for dentifrice, cosmetics, glues &c. are formed by injection blow-moulding the threaded neck portion thereof being formed in the blow-moulding stage. As shown in Fig. 2, an injection blow mould comprises parts 3, 3<SP>1</SP>, sealing ring 4 and core 7 having a main body 8, shoulder 9, and reduced end 10. Parison P is injection moulded by device 12 and has a flared end with rib 13 opposite the reduced end. Parts 3, 3<SP>1</SP> are opened and the parison P on core 7 with sealing ring closed is transferred to blow mould, Fig. 5, which comprises parts 14, 14<SP>1</SP> and neck ring 16. Air is supplied through core 7 to form the tube 20 having main body 21 with rib 13, shoulder 22 neck 23 with threads 24 and sealed end 25 Tube 20 is ejected by a further air blast or mechanically. Preferably, the ribbed end of the tube is trimmed off and end 25 drilled to form an opening. The moulds may be multicavity, co-operating with a plurality of cores. The moulding material is preferably polyethylene or ethylene copolymer or another thermoplastic. The moulds may have cooling ducts, guide pins, &c.
