Abstract

A paperboard carton for containing and pouring liquid has a pour spout fitment adhesively secured to its upper surface and at least partially over a reinforcing patch on said upper surface to spread the upward force exerted by opening the fitment over an area of the carton surface larger than the bottom surface of the fitment so as to prevent the fitment from being torn away from the carton surface. In addition to the force distribution, the tensile strength of the added patch material is much greater than the strength of the carton coating, thus this new patch material becomes the primary seal.
