A carton has top and bottom walls that are interconnected by a pair of opposed side walls to form a tubular structure. An end closure structure is provided at each end of the tubular structure to at least partially close that end. One or each of the end closure structures includes a bottom end flap, a pair of side end flaps and a pair of web panels. The bottom end flap is foldably joined to the bottom wall and extends upwardly. The side end flaps are foldably joined respectively to the side walls and extend to each other to traverse the respective end of the tubular structure and to cover at least part of the bottom end flap. Each web panel foldably interconnects the bottom end flap and the respective side end flap and is disposed in a face-contacting relationship with the inside surface of the respective side end flap. A pair of first tear lines are formed respectively in the side end flaps. Each first tear line extends between the adjacent side wall and the adjacent web panel. A pair of second tear lines are also formed respectively in the side end flaps. The second tear lines emanate respectively from the first tear lines and extend to each other to form a single continuous line disposed above the first tear lines.
