ABSTRACT:
An ignition safety device in a gas lighter to reliably prevent ignition of the lighter when a safety button is in a locked position, and to allow ignition of the gas lighter when the safety button is moved from the first locked position to a second unlocked position. A projection of the safety button has an end surface that coacts with an end surface of a projection provided in the upper part of the gas lighter when the safety button is in its locked position. The projection in the upper part of the gas lighter is positioned so as to ensure that the two end surfaces securely contact each other. When the safety button is moved to the unlocked position, the projection of the safety button is not aligned with the projection in the upper part of the lighter and therefore, the ignition button of the lighter can be depressed to ignite the lighter.
