Abstract

997,784. Moulding blanks for containers- JOHN WADDINGTON Ltd., and T. N. GAUNT. Aug. 27, 1962 [July 7, 1961], No. 24598/61. Heading B5A. [Also in Divisions B6 and B8] A blank of thermoplastic material is provided with predetermined grooves along which the blanks are folded into cartons. The grooves are produced by placing the heated sheet on a flat plate 2 bearing engravings 3 or projections corresponding to the fold lines and then either applying pressure to face the sheet against the engravings or projections, or applying an air-tight seal to one side of the sheet 4 and forming a vacuum which sucks the material into the engraving or over the projection. The thermoplastic material may be polystyrene, polyvinyl chloride, cellulose acetate, polycarbonate, polypropylene or polyethylene.
