Abstract
Abstract The present invention relates to a carton having integral collapsible pour spout opening which can either be extended into a spout or collapsed to form a flush top closed package. The pour spout portion of the carton is formed by a series of cut and scored triangular panels in the top closure flaps thereof which triangular panels include an attached cover panel for overlying the pour spout panels and the pour spout opening when the carton is not in use, the improvement comprising the arrangement of the various pour spout panels and the cover panel to permit access to the pour spout without the necessity of providing tear-away elements or perforated areas in the carton top.
