A frangible pour spout construction is improved by the addition of reinforcing webs at the upper plug portion. These webs function to localize the upward pulling force to thereby concentrate the rupture force at the frangible connection between the upper plug and lower pour spout portions. This insures that the pulling force is concentrated so that the frangible connection will rupture prior to the entire fitment being pulled off of the container to which the fitment is secured. The upper plug, later to function as a cap or stopper for the lower spout portion, is provided with a pull ring. The entire construction is die molded, as for example of polyethylene, with the pull ring being molded substantially at 90°from its flat or storage position. A pair of lugs carried by the upper plug holds the pull ring down in its storage position.
