Abstract
A blank for forming a gable top carton is provided along with the carton formed therefrom. The blank comprises first through fourth side panels and a side glue panel consecutively articulated to one another along parallel fold lines for defining the side walls of the gable top carton to be formed from the blank. Top and bottom panels are articulated to the opposed ends of the respective side panels and glue panel. The blank further comprises a skived flap extending entirely along one edge of the blank and adjacent the glue panel and the top and bottom panels articulated to the glue panel. The skived flap is defined by a rabbeted portion extending into the exterior surface of the blank, and is appropriately dimensioned to enable the skived flap to be folded over onto the exterior surface of the blank along the entire length of the edge. The skived flap can be adhered in face-to-face contact with the exterior surface of the blank to ensure that the liquid stored in the gable top carton formed from the blank does not directly contact the edge of the paperboard material, thereby preventing wicking of liquid through the paperboard material.
