  • Patent number: 4817363
    Abstract: A fitment inserter machine, such as a machine for inserting a spout into the top opening of a blow molded container is disclosed. A conveyor continually moves containers through the machine. A transfer arm and rotary placer removes the lowermost spout from a vertical dispenser and places the spout on a moving container. Jaws grasp the container finish while it is still moving and hold the finish while a pressing head mounted on a flying table moves downwardly to press the spout into correct alignment with the container.

  • Patent number: 4640855
    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.

  • Patent number: 4002005
    Abstract: Multiple rows of nestable containers are continuously filled with product and sealed with a cover structure. Every other container in each row is inverted and the container inversion is alternated between rows to produce alternate rows of alternately inverted containers which are accumulated into nested groups. Cardboard support blanks are fed beneath the container groups in timed relationship with their accumulation into groups. Each group and cardboard support are simultaneously conveyed from the accumulation area to position the group on the cardboard support and form an assembly. The assembly is enveloped in a sheet of heat shrinkable film which is shrunken about the assembly to complete the package.
