Abstract
Abstract A plastic container with an integral spout comprising a hollow body, a neck having an outer wall and an inner wall formed with internal threads and a spout connected to the inner wall and extending outwardly of the container. The container is formed by blow molding to form the hollow body, a neck forming portion extending from the hollow body and a spout forming portion extending from the neck forming portion. Thereafter, the neck forming portion is heated and the spout is moved inwardly of the hollow body to reform the neck forming portion into the inner and outer wall. Thereafter, the threads are pressed internally on the inner wall of the neck. Alternatively, the threads may be formed during the blow molding.
