Abstract

1378553 Blow-moulding; multi-chamber containers VEREINIGTE DEUTSCHE METALLWERKE AG 7 Aug 1972 [9 Aug 1971] 37039/72 Heading B5A Multi- or two-chamber plastics containers are produced by extruding a thermoplastic tube, longitudinally pinching and fusing the wall of the tubing together along its entire length to divide it longitudinally into two or more cohering but non-communicating component tubes and blow-moulding the component tubes. As shown in Figs. 3, 5, tubing 1 is extruded between the halves 3, 3<SP>1</SP> of an open blowmould 2 having parting walls 4, 4<SP>1</SP> which, when the mould closes, pinch the tubing 1 longitudinally to fuse opposite sides together at seam (6, Fig. 2, not shown). A calibrating mandrel 8 having blowing orifices 9, 9<SP>1</SP> is then used to blow-mould the component tubes into chambers 10, 10<SP>1</SP> of semi-circular cross-section.
