Abstract: Disclosed is a piezoelectric type gaslighter equipped with a thumb-latch for preventing an inadvertent fire which may be caused, for instance, when a child plays with a gaslighter. A gaslighter according to the present invention includes an intermediate casing and a piezoelectric unit having a movable operating part. The intermediate casing has a cross slot opening with a thumb-latch slidably fitted therein whereas the movable operating part has a longitudinal slot groove. The piezoelectric unit is properly inserted in the intermediate casing so that the longitudinal slot groove of the movable operating part intersects the cross slot opening of the casing. With this arrangement when the thumb-latch is displaced to the crossing at which the longitudinal slot groove intersects the cross slot opening, the movable operating part can move to strike the piezoelectric element for producing a small flame. Otherwise, the movable operating part is latched.

Abstract: Disclosed is a gas lighter equipped with a safety lock, which is an L-shaped slidable stopper so slidably fitted in the re-entrancy of the thumb-push gas lever that its vertical pin may be above a hole of the lighter housing when its horizontal slide is pushed in the re-entrancy of the gas lever, thus permitting the descent of the gas lever for lighting, and that its vertical pin may be off from the hole of the surface of the lighter housing when its horizontal slide is drawn backward, thus preventing the descent of the gas lever for lighting. A gas lighter according to the persent invention assures in its locking condition that an accident which may be caused when a child plays with the device, such as a burn or an accidental fire is prevented.

A gas lighter according to the present invention assures in its locking condition that an accident which may be caused when a child plays with the device, such as a burn or an accidental fire is prevented.

Abstract: Disclosed is a rod-shaped piezoelectric igniter comprising a liquefied gas reservoir section equipped with an ejection valve, which is responsive to operation of an acutating lever for ejecting gas; and an ignition mechanism section including an ignition nozzle functioning as an ignition electrode with a counter electrode projecting inward from a metal hollow cylinder encircling the ignition nozzle, a piezoelectric generator mechanism partly exposed to permit access thereto for pushing operation, the minus terminal of the piezoelectric generator being responsive to the pushing operation for operating the actuating lever, an electrically conductive conduit connecting the ignition nozzle to the ejection nozzle, and a lead conductor connecting the metal hollow cylinder to the plus terminal of the piezoelectric generator mechanism.

Abstract: Disclosed is a rod-shaped gas igniter including an ignition nozzle, a finger-operative piezoelectric generator, a liquefied gas reservoir, means responsive to the operation of the piezoelectric generator for opening valve means associated with the liquefied gas reservoir, thereby permitting gas to flow to the ignition nozzle, an inner protecting hollow cylinder having longitudinal slots circumferentially spaced for ventilation and enclosing the ignition nozzle, and an outer metal hollow cylinder having longitudinal holes circumferentially spaced for ventilation and encircling the protecting hollow cylinder, the longitudinal slots and holes of the inner and outer hollow cylinders being staggered to each other.

Abstract: A portable, fail-safe aerosol container comprising an elongated tank body having an ejection nozzle head to be depressed for dispensing a spray of aerosol, an elongated guard rotatably fixed to the top of the tank body about the ejection nozzle head having slots on each of its long sides for alignment with the ejection nozzle on the nozzle head and a lock for preventing depression of the ejection nozzle head when the guard is in alignment with the tank body and permitting depression of the ejection nozzle head when the guard is turned to lie across the aerosol container with a slot on either of the long sides of the guard in alignment with the ejection nozzle.

Abstract: A pressure container for dispensing a flowable product in the form of an aerosol. The pressure container includes a container body having a hollow plug welded to an inner surface of the body. A spring-loaded spouting tube having a valve port is slidably received in the plug with a portion of the tube projecting above the plug. An annular deformable gasket is disposed about the spouting tube for normally closing the valve port. An externally threaded guide member is disposed about the spouting tube and is seated on the gasket. An actuator having a spray nozzle is fitted on the spouting tube projecting portion.

Abstract: Disclosed is a valve for use in a pressure-resistant container, permitting the full filling of the container with a liquefied gas thanks to a well controlled gas depletion path. The opening and closing of the depletion path is effected by bringing two opposing contact members apart and close to each other whereas the flow rate of gas depletion depends on the roughness of the contact surface areas of the opposing member. Such an appropriate depletion path can be made without difficulty such as encountered with formation of depletion path with recourse to machining.

Abstract: An electronic gas lighter is provided with an electricity generating device having a movable electrode. A movable part carrying the movable electrode is moved downward to ignite fuel discharged from a nozzle disposed on a fuel tank. A partition is provided between the movable part and the nozzle.

Abstract: In an electronic gas lighter comprising a plastic body, a flame orifice cap having a flame orifice aligned with a fuel outlet nozzle, and an electronic ignition means, the flame orifice cap is provided with a vent opening and a heat dissipating plate. The heat dissipating plate integrally extends from the flame orifice cap along the flow of fuel gas discharged from the nozzle.

Abstract: In a cigaret gas lighter having a plastic gas tank and a burner mounted thereon, a heat collecting tube or rod is provided along the wick of the lighter hanging from the burner to the liquified fuel gas in the tank. The upper end of the heat collecting tube or rod is in direct contact with the lower surface of a pin disk located within the burner to effectively transmit heat to the pin disk that is disposed beneath the nozzle bottom in the burner.

Abstract: A fuel tank of a disposable cigarette gas lighter is constituted of a tubular tank body of uniform cross section having a plurality of borings, a bottom cap attached to the lower end of the tank body and a lighting means holder attached to the upper end of the tank body. A part of the wall between the borings of the tank body is removed at either end thereof to provide a communicating path between the borings. The tank body which shares the major portion of the fuel tank is produced by cutting a continuous pipe of uniform cross section having a plurality of borings made by extrusion molding.

Abstract: A disposable cigarette gas lighter has a snuffing cover on a plastic fuel reservoir. The snuffing cover is rotatably mounted on the lighter independently of a sparking wheel. When lighting the lighter, the snuffing cover is opened with the thumb which is used for rotating the sparking wheel so that the snuffing cover will be opened when the sparking wheel is rotated. When closing the snuffing cover, the snuffing cover is closed independently of the sparking wheel. Further, the snuffing cover can be opened without rotating the sparking wheel so that the sparking wheel is not rotated when the snuffing cover is accidentally opened.

Abstract: A disposable cigaret lighter has a snuffing cover which is closed when the flame is to be put out. The snuffing cover is provided on the top of the lighter independent of any of the operating members of the lighter such as a nozzle opening lever and a sparking wheel. The snuffing cover may be mounted on the windbreak wall of the lighter slidably or rotatably.
