Abstract
A torch includes a body, a fuel tank and a microjet burner. The torch also includes an ignition button that is movable relative to the body between an upper position and a depressed position, and a cap assembly, which includes a lower cap and a safety cap rotatably coupled with the lower cap. The safety cap includes an ignition button guard, defines a flame portal, and is rotatable between a closed position and an armed position. When the safety cap is in the closed position, the ignition button guard is aligned with the ignition button and inhibits access to the ignition button, and the safety cap covers the microjet burner. When the safety cap is in the armed position, the flame portal is aligned with the microjet burner, and the ignition button guard is misaligned with the ignition button, and access to the ignition button is unobstructed.
