A novel carton structure useful for a variety of pourable products and having an integral pouring spout is described. The carton is formed by conventional blank die cutting, gluing, forming and filling. When first constructed, a secure integral enclosure is provided. The carton is readily opened and the spout formed by tearing along pre-formed lines of perforation specifically located for the purpose. Once the carton has been opened, product may be poured full-width from the carbon via the spout. The construction of the spout permits opening to a controlled extent, reclosure to a friction-locked enclosure and guided movement between the two.
