Abstract: A convertible cart and container may be assembled by folding a blank of paperboard and attaching a wheeled carriage thereto. The blank includes a floor panel connected to front and back panels along fold lines, the back panel having side panels connected thereto along fold lines. The blank includes a plurality of lines of weakness which facilitate separation of the assembled cart into an upper handle portion which may be discarded and a container portion. The assembled cart conveniently includes an opening in a front panel and a pair of doors which are hinged to the front panel along fold lines to permit access to the chamber within the cart while obscuring the contents from view. The cart includes a top flap portion which may be separated from the upper handle portion and folded over a substantially rectangular box-type container for enclosing items received in the container and permitting shipping of the reduced size container without the need for emptying the contents for conversion.
