<p>A packaging apparatus for erecting, filling and closing paperboard cartons of a type that are initially supplied in a flattened condition and have four body panels, lower closure flaps; and an open top, and a separate plastic cover. The packaging apparatus opens and erects the paperboard cartons in an inverted position and advances the cartons while inverted along a path past a filling station. Covers are fed to a position below the cartons and are pressed into the open ends of the cartons as they are advanced along the path and before they reach the filling station. The lower closure flaps are thereafter folded to close the cartons.</p> |
