Abstract
An induction sealing device is utilized to seal a closure to a container on a packaging machine. The induction sealing device has a recess area for receiving a spout of a closure during the application process. A current is induced in a metal medium that generates heat to melt and chemically bond a closure to a container. The metal medium may be found in either the closure or the container.
