ABSTRACT:
A lever formed at least partially as a bimetallic strip engages between the cover and the burner-valve of a gas-type cigarette lighter. When the cover is lifted this lever automatically opens the valve and forms a gas jet that may be ignited with the striker. A cup-shaped extension on the lever at the jet is heated by the flame on the lighter and conducts this heat to a thermodeformable tab on the lever so that after a predetermined amount of heating the tab deforms and disconnects the lever from the burner-valve, allowing this valve to close and shut off the gas flow.
