Abstract: 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.

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.

Abstract: An apparatus for sealing a fin at a gabled end of a carton is disclosed. The apparatus includes a longitudinal force mechanism for applying a sealing force to a first pair of opposed flaps of the gabled end of the carton. The longitudinal force mechanism is movable from a first position in which the gabled end of the carton is in a generally open condition to a second position at which the fin of the gabled end is sealed. A transverse force mechanism applies oppositely directed transverse forces to a second pair of opposed flaps of the gabled end of the carton as the longitudinal force mechanism moves from the first position to the second position. The transverse force mechanism urges the second pair of opposed flaps toward one another during movement of the longitudinal force mechanism. The second pair of opposed flaps are thus urged inward toward one another as the longitudinal force mechanism moves to form and seal the fin thereby preventing "duckbilling".
