A carton is provided with side walls and chamfered corners shaped to securely or tightly enclose a group of cylindrical articles, such as beverage bottles. The curvature of the edges of each side wall is selected to cause the end wall or end closure structure to conform to the cylindrical and tapered shape of articles in the endmost row. More specifically, the end edges of each side wall are substantially concave and their curvature is determined such that the minimum width of each side wall is less than or equal to the width of the top wall. To encourage side end flaps, which partially form the end closure structure, to crease so as to define the chamfered corners, a fold line is formed in the side end flaps.
