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.

What is claimed is: 1. An end loaded carton for enclosing a plurality of articles, said carton comprising: a tubular structure comprising a pair of opposed side walls, each of said side walls comprising a pair of opposing end edges that are at least partially curved concavely toward each other; and an end closure structure for at least partially closing an end of said tubular structure, said end closure structure comprising a pair of side end flaps, each of said side end flaps being hingedly connected to a respective one of said side walls along one of said end edges, said end closure structure comprising an end wall and a pair of chamfered corners; wherein each of said side end flaps comprises a terminated fold line that extends from a first point that is located approximately at a lower end point of a respective one of said end edges to a second point that is spaced apart from the periphery of a respective one of said side end flaps. 2. The carton of claim 1, said tubular structure further comprising a bottom wall, said end closure structure further comprising a bottom end flap hingedly connected to said bottom wall, each of said side end flaps comprising a distal lower end wall portion that is defined in part by a respective terminated fold line, wherein said bottom end flap overlaps said distal lower end wall portion of each of said side end flaps. 3. The carton of claim 2, each of said pair of side end flaps comprising a proximal lower corner portion that is defined in part by a respective terminated fold line and is adjacent to a respective distal lower end wall portion, wherein each proximal lower corner portion forms at least part of one of said chamfered corners. 4. The carton of claim 3, wherein said proximal lower corner portion of each side end flap is angled with respect to an adjacent one of said side walls and with respect to said end wall. 5. The carton of claim 1, said tubular structure further comprising a top wall, said end closure structure further comprising a top end flap hingedly connected to said top wall, each of said side end flaps comprising a distal upper end wall portion, wherein said top end flap overlaps said distal upper end wall portion of each of said side end flaps. 6. The carton of claim 5, each of said pair of side end flaps comprising a proximal upper corner portion that is adjacent to a respective distal upper end wall portion, wherein each proximal upper corner portion forms at least part of one of said chamfered corners. 7. The carton of claim 6, wherein said proximal upper corner portion of each side end flap is angled with respect to an adjacent one of said side walls and with respect to said end wall. 8. The carton of claim 1, the tubular structure further comprising a top wall and a bottom wall, wherein the width of said bottom wall is greater than the width of said top wall. 9. A blank for forming a carton, the blank comprising: a plurality of panels hingedly connected one to the next that can be arranged to form a tubular structure, the plurality of panels comprising at least one side panel comprising a pair of end edges that are curved concavely toward each other; and a pair of side end flaps for at least partially defining end closure structures at opposite ends of said tubular structure, said end flaps being hingedly connected to respective ones of said end edges; wherein each of said end flaps includes a terminated fold line that extends from a first point that is located approximately at an end point of a respective one of said end edges to a second point that is spaced apart from the periphery of a respective one of said side end flaps. 10. A package, comprising: a group of cylindrical articles each having a relatively larger bottom portion and a relatively smaller top portion, said articles being arranged in one or more rows; and a carton enclosing said article group, said carton comprising: a tubular structure comprising a pair of opposed side walls, each of said side walls comprising a pair of opposing end edges that are at least partially curved concavely toward each other; and an end closure structure for at least partially closing an end of said tubular structure, said end closure structure comprising a pair of side end flaps, each of said side end flaps being hingedly connected to a respective one of said side walls along one of said end edges, said end closure structure comprising an end wall and a pair of chamfered corners; wherein each of said side end flaps comprises a terminated fold line that extends from a first point that is located approximately at a lower end point of a respective one of said end edges to a second point spaced apart from the periphery of a respective one of said side end flaps. 11. The package of claim 10, wherein a curvature of said end closure structure provided by associated ones of said end edges and chamfered corners conforms to the taper of the articles that are adjacent to said end closure structure. 12. The package of claim 10, wherein said second point on each of said side end flaps to which a respective one of said fold lines extends is positioned substantially at the height of a shoulder of each of said articles. 13. The package of claim 10, wherein a portion of an article that is adjacent to said end closure structure extends outwardly beyond a respective one of said end edges of each of said side walls.
