Abstract: A gas lighter is provided which is highly reliable and cannot release fuel gas even when its actuation member is depressed, as long as a child resistant locking device has not been moved to its unlocking position. The gas lighter includes a fuel-supplying device for supplying fuel gas to a nozzle through a valve mechanism, an action lever, which must be rotated about a rotation axis to open and close the valve mechanism of the fuel-supplying device, an igniter for igniting fuel gas discharged through the nozzle, and the actuation member, which when depressed drives the igniter. An unlocking member is normally held in a locking position where it holds the rotation axis of the action lever in a first position where depression of the actuation member cannot rotate the action lever to open and close the valve mechanism.

Abstract: A noncontrolling type valve for use in a gaslighter, a portable cooking stove and other burners, which valve comprises a valve body push-fitted in a recess formed in the top plate of a gas container; and a filter positioned under the valve body to permit the gas to flow at a controlled rate. The valve according to the present invention uses a porous concave object as a filter. The filter is laid on an impermeable, resilient membrane. The gas invades the concave space of the porous object from the outside to flow in the valve opening. The rise of the surrounding temperature will cause the membrane to bend yieldingly upwards to cover the inside of the porous object, thereby preventing the increase of the gas flow passing through the porous object over a predetermined flow rate.
