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, fold-in panels, one of which cooperates to form the flat top configuration when closed, but serves as a substantially longer pour spout when opened by virtue of incorporating the top portion of the front wall panel as a part thereof. 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 and on a portion of the side wall panels adjacent the pour spout.
