Abstract
A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A dispensing opening is formed, as by die cutting, in a panel of the carton. A pour spout carries a flange extending from the edge of the dispensing hole to a location radically beyond the dispensing opening, the flange sonically bonded to the outer barrier layer along an annular outermost knurled zone. The knurled zone sonic horn configuration yields pour spout attachment times and spout attachment integrity superior to known prior spout attachment methods and spout constructions.
