Abstract: Liquated gas lighter with non-adjustable flame height, comprising a gas reservoir, a burner and a gas flow limiting device consisting of a microporous membrane gripped between a first seating body and a second seating body. First seating body has a through hole that comes out on one side directly into microporous membrane and on the other side into reservoir. Second seating body has a seating surface in contact with membrane, a groove formed in seating surface, an outlet duct and a linking passage between groove and outlet duct. Through hole is facing, at least partially and through microporous membrane, groove.

Abstract: Pocket lighter with a child resistance mechanism, of the type comprising a liquated gas reservoir, a combustion chamber, a valve connecting liquated gas reservoir to combustion chamber, a lever that activates valve, a flint, a toothed wheel mounted in rotation around an axis and which rubs against said flint and at least one thumb wheel coaxial with axis and integral with toothed wheel. Thumb wheel has on its periphery a plurality of radial projections alternated with seating areas with respect to which said radial projections project. There are between three and ten radial projections, and they are free from any contact with any other element of the lighter.

Abstract: Liquated gas lighter with non-adjustable flame height, comprising a gas reservoir (12), a burner (1) and a gas flow limiting device consisting of a microporous membrane (2) gripped between a first seating body (3) and a second seating body (4). First seating body (3) has a through hole (17) that comes out on one side directly into microporous membrane (2) and on the other side into reservoir (12). Second seating body (4) has a seating surface (22) in contact with membrane (2), a groove (6) formed in seating surface (22), an outlet duct (7) and a linking passage (18) between groove (6) and outlet duct (7). Through hole (17) is facing, at least partially and through microporous membrane (2), groove (6).

Abstract: A refill device for a gas operated lighter, which refill device includes a gas container with an outlet valve; a separable cover fitted on the container over the valve; various separate compartments in the cover and each compartment containing a respective outlet valve adapter for different size and style inlet valves on different lighters; the adapter containing cover having a cap thereover rotatable with respect thereto and having an access aperture therethrough for access to each adapter in turn.
