Abstract
A gable-top carton has at least half, if not all, of its spout-forming, folded-in, top sealing panels (33) projecting above an adjacent non-folded-in top sealing panel (32) to permit a user to grasp that projection and pull it forward to open the spout. To provide a flattened gable-top carton, the other non-folded-in top sealing panel (34) may be extended to be tacked down onto an opposite top obturating panel (22) and be formed with a tear strip to facilitate detachment of the turned-down sealing fin (32-35) from the tacked-down part of that other non-folded-in top sealing panel (34) and to cover a pouring edge zone of the adjacent half of the spout-forming, top sealing panel (33). The carton can be made from an appropriately shaped and scored blank.
