Abstract: This lighter I of the type comprising a reservoir for containing liquefied petroleum gas, a valve (3) mounted on the reservoir and permitting the gas to leave the same, a valve opening mechanism (4, 5), as well as an ignition system comprising a flint (6) co-operating with a spark wheel (7) rotationally operated by at least one circular thumb wheel (10) mounted co-axially with the spark wheel. This lighter is characterized in that each thumb wheel (10) is independent of the spark wheel (7) and can pivot around its axis independently of the spark wheel, and in that rotational frictional engaging means are provided between the spark wheel and the at least one thumb wheel (10) when a force is exercised on the thumb wheel with a radial component having a value greater than a predetermined value.

Abstract: A lighter actuated by a push-control member (24) which can move in a longitudinal direction, and which resists use by children, comprising a lighter-body (2) and lighting means comprising said push-control member. The push-control member (24) is guided in two essentially perpendicular directions, a longitudinal direction (36) in relation to the lighter body (2) and a transverse direction (38, 56, 60) in relation to the lighter body (2). The push-control member (24) has an abutment face (34, 46, 52, 53) which is normally opposite a counter-abutment surface (34, 44, 2) integral with the lighter-body (2), and the push-control member (24) is displaceable in the transverse direction (38, 56, 60) such that its abutment face is then in a non-active position relative to its counter-abutment surface.
