Abstract
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.
Claims13
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.
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.
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.
