Abstract: An ignition system comprising a metal plate having a pyrogen on one side thereof, a turning shaft journalled by the plate, and a sparking wheel secured to the shaft. A flint is supported by the plate and pressed against the wheel. An opening is formed in the plate adjacent the wheel, and a screen is formed on the plate adjacent the opening. The screen deflects sparks through the opening to the pyrogen, and the screen is preferably angled to efficiently deflect the sparks. The igniter is mounted in a self-heating container for heating food or a liquid.
