ABSTRACT:
There is disclosed herein a flat top end closure for a liquid carrying container, which includes two oppositely disposed, overlapped outer closure panels, and two oppositely disposed, three-segment fold-in panels, one of which serves as the pour spout when opened. Each of the three-segment fold-in panels includes a substantially triangular panel portion defined by converging diagonal score lines extending from the upper edge of the tubular container body, and a pair of fold-back panels integrally connected to and folded between the substantially triangular panel portion and the respective adjacent outer closure panels. Diagonal opening-assist score lines are formed on the outer closure panels. Adhesive patterns to facilitate the opening process are formed on the outside surface of the three-segment pour spout and on the inside surfaces of the pour spout fold-back panels and the adjacent panel segments bounded by the diagonal opening-assist score lines.
