At least one of the opposed ends of the tubular carton is closed by a composite end wall. The composite end wall includes pair of first and second side end closure flaps hingedly connected to the side panels of the carton along first fold lines respectively. Each of the first fold lines is interrupted by a pair of at least substantially triangular panels, each of the pairs of at least substantially triangular panels is formed such that a lowermost triangular panel of the pair is disposed below the respective notional longitudinal line and such that an uppermost triangular panel of the pair is disposed above the respective notional longitudinal line.
