Abstract: A semi-stiff cardboard carton produced, stored and transported flat until required for use, when it is set up in a single simple operation. The carton is produced from a blank having a rectangular base, side and end panels, the end panels having flaps glued to adjacent side panels. The major symmetrical axis of the blank is a first fold line and secondary fold lines extend between each apex of the base and the first fold line, the secondary fold lines lying on the interior bisector of the angle formed between edges of adjacent end and side panels. When folded, the end panels are folded in half toward the centre of the carton so that the side panels come together, and the base folds in half along the major axis and projects downwardly from the side panels.
