ABSTRACT:
A corrugated paperboard carton of the top lifting type and a unitary blank for forming it. The upper end of each sidewall is provided with a pair of flange panels, the latter folded upon themselves and glued together to form double thickness flanges extending around the upper rim of the carton, each positioned parallel to its respective sidewall. The free side edge of one flange panel carries a tongue received between next adjacent flange panels, the tongue glued in place. A flexible reinforcing strip is carried by one series of the pair of flange panels, the flexible strip extending from the tongue and across the flange panels. The ends of the reinforcing strip overlap, being separated by the thickness of the tongue. The carton is particularly useful in conjunction with lift trucks, the blades of such a truck being inserted between the flange panels and any corresponding sidewall for lifting the loaded carton.
