A package comprises a top-sealed gable-top carton, a flowable substance contained in the carton, and a pour spout fitment (72) openable to pour the substance from the carton, the carton including a top closure including a front roof sub-panel (130) carrying and sealed to the fitment (72), the carton also including a front body sub-panel (140), the boundary zone between the roof sub-panel (130) and the front sub-panel (140) comprising an edge protruding into the front sub-panel 140, and the fitment (72) extending to adjacent to that edge. It is thereby possible to provide on a gable-top carton a pour spout fitment having a greater through-flow cross-sectional area than would be the case if the above-mentioned boundary zone were not to protrude into the front sub-panel. |

1. A carton blank for a rectangular gable-top carton and comprising a row of panels arranged side-by-side, the boundaries among said panels being defined by a set of lines of weakness parallel to each other, one of said panels including not only a first region for forming a first top obturating sub-panel comprising a first group of a plurality of substantially triangular sub-sub-panels defined by lines of weakness, but also, disposed outwardly thereof, a first top sealing sub-panel, another of said panels immediately adjacent said one of said panels including not only a second region for forming a quadrangular top obturating sub-panel having an opening zone, but also disposed immediately outwardly thereof and separated by a first linear weakness, a second top sealing sub-panel, and, immediately inwardly thereof, a body sub-panel, said second region including a boundary zone furthest from said first linear weakness, said boundary zone having a second linear weakness which is discontinuous and/or comprises linear weakness portions which extend transversely of said row of panels, and said opening zone includes respective opposite peripheral portions which extend to the region of the first and second linear weaknesses. |
