    Patent number: 6435384
    Abstract: A method is provided for forming a recyclable plastic container component with an integral preform. A preform is placed within a mold recess. The mold is closed to capture the preform, thereby forming a flow passage with a shape corresponding to contours of the container component. Plastic is injected into the flow passage under pressure. The injected plastic bonds to an edge portion of the preform. The molded component is then cooled and removed from the mold.
