Abstract
A pour spout for a carton is formed from the carton material in two superimposed panels. The outermost panel has an opening and a tab member, the first end of which is connected to the remainder of the panel at a fold line. The second or opposite end of the tab member is part of the perimeter of the opening. The first and second ends of the tab member are defined by parallel rows of perforations. The inner panel includes a tab member which is aligned with the first tab member. A pair of wing members extend from fold lines at opposite side edges of the inner tab member. The wing members may have an arcuate edge and may include a projection which will limit pivotal movement of the spout formed by the tab members and wing members. The superimposed panels may be overlapping side panels, overlapping top panels, or a combination of side panels and top panels having extensions which overlap the side panels. In one embodiment, a separate insert serves as the innermost panel.
