ABSTRACT:
A one-piece blank which may be formed into a liquid-tight carton is T shaped and is comprised of side wall panels integrally interconnected and numbering three or more to provide a carton of polygonal cross section. One of the side wall panels has integrally connected carbon end closure panels to be folded down upon and sealed to sealing tabs of the other side panels after the blank has been formed by a side-seam operation into an open-ended tube. The end closure panels are of substantially the same area as the cross-sectional area of the carton but are not provided with sealing flaps. They are embossed marginally around their free edges to provide a curvature for contact with the sealing tabs when the ends of the carton are closed by rendering the closure panels and the sealing tabs mutually adhesive and pressing the closure panels down upon the sealing tabs.
