Abstract
A carton, having reinforced handle openings which define handles, includes a tubular structure that is formed from multiple walls. An edge flap connects two of the walls. The carton also includes end closures at each open end of the tubular structure. The end closures each include end flaps that have features that define the handles. The end closures also include edge flap reinforcing panels that are hingedly connected to the edge flap and further define the handle. Specifically, a reinforcing edge of the edge flap reinforcing panel is disposed in reinforcing proximity to a handle opening so as to reinforce at least a weight bearing edge of the handle opening to define a handle with a multi-ply thick weight bearing edge.
