ABSTRACT:
A lid for a liquid pack is formed from a plastic material and includes a substantially flat end wall. A pouring spout is disposed within the outside contour of an outer first plane of the lid. An opening flap portion closes a pouring opening, and a handle is secured to the opening flap portion by a hinge. The opening flap portion is connected by way of an endless weakening line to the wall of the lid, and a collar is disposed at the periphery of the lid at an inwardly displaced position for mounteing to a side wall of the pack. The weakening line extends in a second inner plane and at a spacing below and parallel to the first outer plane, with the spacing between the two planes being greater than or equal to the height of a collar portion projecting outwardly from the weakening line at the opening flap portion. The lid is first molded with the handle extending normally from the end wall, the mold is opened, and the handle is folded to a position substantially against the end wall while the handle is still in a plastic state.
