ABSTRACT:
The present device includes a primary coil wound on a spool having an opening at one end for receiving the nozzle of a container. The coil is connected to an alternating current source. The nozzle of the container has a conductive portion which functions as a secondary inductor having internal resistance. Current is induced and dissipated in the conductive portion thereby heating the portion and the substance contained therein.
