A method for the manufacture of a container including the steps of forming a pair of end walls by adhesively bonding a plurality of corrugated panels in facing relation to each other to form the end walls with the flutes thereof disposed in substantially parallel relation to each other; sawing the end walls to form end walls having end surfaces substantially normal to the panels; positioning the end walls in spaced, substantially parallel relation; extending a wrapper having lid portions about the end walls in adhesive attachment thereto with the lid portions movable between opened positions for filling the container and closed positions having portions disposed in spaced relation to each other to define an opening; and, after filling the container as formed, sealing the container by extending a substantially transparent strip of tape across the lid portions and the opening to retain them in the closed positions and forming a window for viewing the contents of the container through the opening.
