The disclosure relates to a carton blank (10) comprising two overlapping circular panels (11) each having three independent elliptically shaped segments (12) and a shared elliptical segment (11a) between the respective panels delineated by preformed crease lines (13) around centre portions (11a). The segments are folded up about the crease lines with respect to the centre portions to create a carton having an interconnected tray and lid which, when folded together, is of generally square form with four concave elliptically shaped side walls (15) and conversely curved or domed top and bottom walls (16). |
