Abstract: There is disclosed herein a flat top end closure for a liquid carrying container, which includes two oppositely disposed, overlapped outer closure panels, a folded over panel segment on one of them, and two oppositely disposed, fold-in panels, one of which serves as the pour spout when opened. Each of the fold-in panels includes a plurality of score lines, permitting each of the fold-in panels to be folded into two four layer thick portions beneath the outer closure panels such that no raw edge is adjacent the liquid contents. First and second lift tabs are formed on the edges of one of the outer closure panels and the pour spout fold-in panel, respectively. Diagonal opening-assist score lines are formed on the outer closure panels adjacent the pour spout.
