The present invention may be utilized as a single station integrated with a standard form, fill and seal machine. The present invention is able to retrieve fitments from a source, apply the fitments to a container and seal the fitments to the container at a single station. The design of the present invention requires only minimal space on a form, fill and seal machine. In practicing the present invention, an anvil retrieves a fitment from a source and then translationally retreats to a position for longitudinal descent into a container. The anvil, with the fitment attached, longitudinally descends into the container to a position parallel to an incision previously incised into the container wall. The anvil proceeds forward to the incision, substantially recovering the translational retreat discussed above, only at a lower level. Once the fitment is positioned therethrough the incision, a sealer permanently attaches the fitment to the container. The anvil then retreats to a position for longitudinal ascent and the container proceeds to the next station. The process is repeated for subsequent containers. By inserting and sealing a fitment to a container at a single station, the present invention is able to substantially diminish any opportunities for the fitment becoming disengaged from the container prior to sealing of the fitment to the container. |
