A gable top carton and its corresponding carton blank are disclosed. The carton includes curved side creases that are defined by curved score lines that divide one or more side panels from a top gabled structure and/or a bottom structure. The gabled structure includes pairs of diagonal creases defined by diagonal score lines. The diagonal score lines form an apex at one end and extend to vertical score lines that separate the side panels of the carton at the edge between adjacent side panels. The diagonal score lines form an angle with the vertical score lines. The vertex of the angle formed is coincident with the vertical score line to facilitate folding and create better quality corners by reducing bunching of carton material at the corner.
