  • Patent number: 5570834
    Abstract: A box doubles as a shipping carton and a dispensing container for light weight roof fasteners. The box has two end walls, each with a channel-shaped perforation therein. Top flaps connected to the end walls along respective foldlines are formed with cutouts. The cutouts in each top flap align with the perforation in the associated end wall when the top flap is folded over into facing contact with the end wall. The perforations and cutouts are offset from vertical centerlines of the end walls and top flaps. The perforations are punched out to create tabs that are pushed through the top flap cutouts, and to simultaneously produce openings in the end walls. A long strap is inserted through the cutouts and openings and looped under the box. A person can carry the box and roof fasteners in it by slinging the strap over his shoulder.
