<p>A blank for forming a spouted gable-topped carton consists of paperboard coated on both faces with thermoplastics and is provided with a strawhole device including a tear strip located centrally of a pair of top closure sub-panels 42 and 52 and bounded by two incision lines 6. The lines 6 penetrate only partly through the thickness of the blank from the carton outside surface. Formed in the carton inside surface of the sub-panel 42 at a location between the lines 6 is a circular closed loop of incision 7 which penetrates only partly through the blank from that surface. In the free edge of the sub-panel 52 are formed two notches 8 leading into the lines 6. The bottoms of the notches 8 have a third line of incision 9 extending between them, which penetrates only partly through the blank from the carton inside surface. Formed centrally in the free edge of the alternate top closure sealing sub-panel 54 is a recess 10 the base of which is straight and co-linear with the line 9.</p> |
