US Patent 7601111 Gusseted carton

A carton includes a bottom receptacle defined in part by the bottom panel, the side panels, and gusseted end panels. The bottom receptacle can be constructed without glue seals so that the receptacle is liquid-tight. An opening feature in the top panel allows the carton to be opened and to expose the carton contents. The carton is formed from a blank that is folded and glued in a manner that facilitates loading of the carton, and allows the carton to be opened to a relatively wide top opening.
