When the flame during combustion extinguishes due to the influence of wind or liquid spillage in the combustion state, the bimetal member 41 deforms in the retreating direction as the temperature decreases, and the regulating member 42 rotates. As a result, the hook portion 42c is disengaged from the ignition lever 33, and the ignition lever 33 returns and rotates in the ascending direction to stop the gas supply, thereby preventing the gas from being blown out in the fire extinguishing state. When the fire is extinguished, the control member 18 is forcibly inserted by inserting the operating rod 18 extracted from the ignition position into a fire extinguishing position corresponding to the engaging portion 46a of the fire extinguishing lever 46 and pressing down the fire extinguishing lever 46. The ignition lever 33 is released from the engagement state with the ignition lever 33, and the ignition lever 33 is returned to the fire extinguishing state.

When the can 14 is heated, the flame is ejected from the burner 16 to directly heat the bottom of the can body 14a. The lower end of the partition member 13 is lower than the bottom of the can body 14a. Due to the formation, the hot air generated by the flame of the burner 16 cans 14 inside the partition member 13.
