Abstract
1,216,804. Sheet forming. BELLAPLAST HELLER & CO. 19 May, 1969, No. 25346/69. Heading B5A. [Also in Division B8] A false-bottomed container is blow moulded from a sheet of heat-softened thermoplastic material in a mould having a raisable base plunger 8, the part of the mould initially engaging the region 13 of the sheet to be deformed by the raising of the plunger, and the plunger itself, cooling the sheet to a lesser extent than the rest of the mould to ensure sufficient pliability. of the sheet in that region. The region 16 of the sheet directly above region 13 is formed with axial ribs 51 against which the region 13 is forced by the raising of the plunger, the movement of the plunger being stopped when the base of the container is level with the upper shoulder 52 of the ribs.
