ABSTRACT:
This invention is a safety device for cigarette lighters fueled by butane or other compressed or liquified gas. The invention is a barrier adapted to selectively engage the thumb layer of the lighter to restrict the motion of the thumb layer, thereby to prevent the release of gas to the burner tip. The restricting member is supported by a band or sleeve that is adapted to at least partially surround and slidably engage the body of the lighter. A sliding motion of the band on the lighter engages or disengages the restricting member with the thumb lever; this motion may be selectively prevented or allowed by the selective engaging or disengaging of a spring-loaded member having a laterally extending projection adapted to fit into an opening in the lighter's structure.
