ABSTRACT:
A pour spout for a paperboard container of either the flat top or gable top type. In one embodiment, a rectangular strip of a rigid plastics material, such as high density polyethylene, is provided with two upwardly liftable, coplanar hinged flaps, integrally formed with the strip. The flaps are aligned with respective vent and pour openings pre-cut in the container top. Upon lifting the flaps from the plane of the strip, an extruded barrier layer (typically a polymer-foil laminate) spanning the pre-cut openings is ruptured and is carried upwardly through the die-cut openings. One opening is a dispensing opening and the other a vent opening. In a second embodiment, a single integral, coplanar and also liftable flap on the rigid strip is employed to define a single pour opening. In a third embodiment, a single integral and copolanar flap on the rigid strip is covered by a flexible strip which is peeled back to expose the flap. The flap is then pushed downwardly to define a single pour opening.
