Carton having foldable bottom and carton blank

摘要

A one-piece carton blank produces a carton which may be glued, shipped and stored in its flat state and which may be erected by pressure on its side panels. The carton includes rectangular bottom panels which are held sandwiched between side panels when the glued carton is in its flat state and which are unfolded 180 DEG upon erection of the carton; bottom side support panels which are unfolded upon erection of the carton to become perpendicular to the carton bottom; fold lines on two opposite side panels to permit the carton to be folded (in its flat state) and unfolded (in its erected state); and, if desired, four corner panels which, for example, may be elliptical or diamond in shape.
