A carton, formed from a unitary blank, comprises four panels (22, 24, 26, 28) interconnected by fold creases (14, 16, 18, 20) to form a rectangular tube. At the end of the tube, a set of four flaps (32, 34, 36, 38, 46, 48, 50, 52) are folded upon each other to form ends of the carton. A spout is formed in one of the four flaps to facilitate the pouring of the content.
