When the flame switching tube (7) is driven to its second position, the flame switching tube (7) opens the air suction port (8b) while the open/close member (7g) closes the air inlet opening (30a).

Abstract: A pocket lighter having a safety mechanism, with a push button; a cavity in which part of the push button is housed; and a free body in the cavity, between the latter and the push button, and depending on the position of the push button there are defined spaces which may be occupied by the said free body, and passages between said spaces, through which the free body may pass. The latter, after the lighter has been ignited, occupies a first space in which it blocks operation of the push button and to remove it from the first space it is necessary to combine certain movements of the push button with others of the lighter; these movements are of sufficient complexity to make it impossible for a child to operate the lighter.

Abstract: In a lighting operation, a lock member is moved from a second lock portion to a first lock portion against a biasing force of a spring, thus enabling a lighting operation of an operating member. When the operating member is moved in this state, a stable lighting operation is performed. In the lighting operation, the lock member is disengaged from the first lock portion upon movement of the operating member, is automatically moved toward the second lock portion to inhibit movement of the operating member upon reception of the rotary biasing force of the spring, is automatically moved to the second lock portion upon reception of an upward force of the spring, and is securely locked at the second lock portion. As described above, this invention provides a cigarette lighter which can prevent an unintentional lighting operation of the operating member and safety of which is thus improved.

The actuating lever can be pushed frontwardly to disengage the locking stem of the lever from the retarding platform to allow an ignition of the lighter wherein the locking stem is depressibly enterable into a cavity formed in the container cover, and after igniting depression of the lever, a restoring spring will restore to retract the lever rearwardly for automatically locking the lever from its depression for a safety purpose.

Abstract: A disposable lighter includes a pushbutton depressible toward a top wall of the lighter's upper end portion to operate a normally closed valve to an open position that releases fuel for ignition by sparks generated by rolling a flintwheel.

A second portion of the spring extends from a resilient first arm of the first portion and defines a stop member slidably mounted on the top wall under a peg depending from the pushbutton. An actuator part of the second portion projects outwardly of the upper end portion and is pushable inwardly to slide the stop member from an initial position that blocks depression of the pushbutton whereby the valve normally cannot be operated to its open position, to an alternate position wherein an opening in the stop member permits depression of the pushbutton by entry of the peg into such opening.

Abstract: A gas lighter with a safety device which is composed of a lock lever and a resilient leaf. The resilient leaf is defined, on the upper portion of a lighter body and on the path of a depressible actuating means, by a pair of slits formed parallel to each other and longitudinally. The resilient leaf, which is slidably surrounded with the lock lever, is at the upper end thereof incurved towards the lighter body. When the lock lever is positioned at the lowermost end of the slits, i.e., a locked position, the incurved portion of the resilient leaf is engaged with a recess at the lowermost end of the actuating means, thereby preventing the depression of the actuating means. When the lock lever is thrust uppermost along the slits, i.e., up to an unlocked position, the incurved end of the resilient leaf is forcibly straightened, whereby the disengaged actuating means can be depressed.

Abstract: A gas lighter has a rocking lever that is pushed down to open a gas-feed valve and/or fire a spark into a jet of gas emitted by the feed valve. A blocking slide on the housing is displaceable transversely between an outer neutralizing position preventing axial downward depression of the lever service end and an inner retracted freeing position permitting the lever service end to be downwardly depressed so that when the blocking slide is in the neutralizing position the lighter cannot be lit. The blocking slide has an outer service end exposed adjacent the lever service end, an inner end engageable axially between the rocking lever and the housing, and a bendable stem extending between the blocking-slide ends. Biasing structure on the housing continuously urges the blocking slide into the blocking position so that the blocking slide must be retained in the freeing position for actuation of the one control means and lighting of the lighter.

According to this lighter, when a lock member is rotated in a lighting operation, the lock member is automatically moved to a position to allow the movement of an operating member upon reception of an upward pressure from a spring. When the operating member is moved after the lighting operaton, the lock member is moved to a position to inhibit the movement of the operating member upon reception of a rotary biasing force from the spring, thus automatically locking a lighting operation of the operating member while the lighter is not used.

Abstract: A gas lighter of compact size and of elongated cylindrical configuration has a head assembly joined to a disposable fuel cartridge. The head assembly includes an aluminum fuel vaporization element located immediately above and in communication with the interior of the fuel cartridge via a tapered lower portion of the element which penetrates a thin wall at the upper end of the fuel cartridge when the element of the head assembly is screwed into the fuel cartridge. The aluminum fuel vaporization element heats in response to vaporization and the resulting expanding movement therethrough of pressurized liquid fuel in the fuel cartridge. This enhances the formation and passing of fuel vapors through a filter consisting of a compressed stack of paper disks disposed within a hollow upper end of the aluminum fuel vaporization element to a valve mounted thereabove. At the same time the filter acts as a barrier to liquid fuel.
