Abstract
A flat top container and the blank for constructing same, including a fin seal which is folded flat, and wherein spaced lines of perforations adapted to provide a tear strip are formed in one outer end closure panel, overlying a separate protective seal strip, formed of aluminum foil or other suitable material, sealed to the inside surface of the panel. The side seam flap which interconnects adjacent side panels has a tab extending from the free edge thereof, and is folded in half to eliminate raw edges inside and to cause the tab to extend beyond the edge of the top closure, to serve as a pouring lip once the tear strip is lifted and the protective seal strip is broken.
