Abstract: Disclosed is an improved inner combustion type of gaslighter whose inner combustion unit comprises: a mixing conduit connected to the upper end of the gas ejection nozzle; a combustion conduit integrally connected to the mixing conduit; a diffusion plate fixed in the boundary between the mixing conduit and the combustion conduit. To improve the burning efficiency by mixing the air and the combustible gas thoroughly in the combustion conduit, the diffusion plate has a plurality of apertures each having an inclined blade to cause the air drawn into the mixing conduit and the combustible gas ejected from the gas ejection nozzle to whirl in eddies.

Abstract: Disclosed is a piezoelectric gas lighter equipped with a safety lock means to prevent undesired ignition. It uses a spring-biased stopper to keep the gaslighter locked and cause an automatic return to locked position after use, thereby guaranteeing prevention of any accident which might otherwise be caused if the gaslighter is inadvertently unlocked or if the gaslighter is by chance unlocked while it is being carried.

Abstract: Disclosed is a file assembly which is adapted to be fitted in and integrally connected to the top of a gas lighter housing, comprising a rotatable file disk and a file block having two opposite support plates each having a semicircular-and-wide-and-narrow slot made on its inside, leaving its outside for ornamental space. Necessary bearings for the flint wheel can be formed by inserting narrow-and-wide rectangular pieces in the semicircular-and-narrow-and-wide slots of the opposite support plates, leaving the semicircular-and-narrow rectangular spaces enough to snugly accommodate the opposite ends of the axle of the flint wheel, thereby eliminating the necessity of making very small pivot holes exactly at selected places in selected parts of the lighter, and hence reducing the manufacturing cost by as much as would cost if such very small holes were made exactly at selected places in selected parts of the lighter.

Abstract: Disclosed is a gaslighter structure comprising a lighter housing equipped with female pivot means provided to the rear, upper side of the housing; a fire-striking unit having push-fit means to integrally combine the unit with the housing, and a cap having male pivot means to fit in the female pivot means of the housing. This arrangement permits the push-fit assembling of the fire-striking unit to the housing and the cap to the housing, thereby simplifying the assembling work and accordingly contributing the automatization of the assembling process.

Abstract: Disclosed is an improved gaslighter structure using a flint for striking flame. To facilitate the assembling work so as to permit automatic assembling, the gaslighter structure uses a mount which is designed to permit the assembling of parts into a flame-striking device and the connecting of the flame-striking device to related parts for synchronizing the flame-striking operation with the ejection of petroleum gas from the nozzle assembly by simply mounting the parts to the mount at selected portions. Then, the mount with the flame-striking device and associated parts is push-fitted to the lighter housing.

Abstract: Disclosed is an improvement of gaslighter structure which has, in the hollow cylinder space at the rear portion of the housing, a push rod having hooks integrally connected to its opposite sides. The push rod is spring-biased upwards, and is pushed against the support piece of the cap, thereby permitting the cap to click shut and open. This arrangement permits necessary parts including a spring to be assembled in a cap pivot-and-latch simply by thrusting them in the rear space of the housing. This reduces the difficulty which otherwise, workers would encounter in assembling parts including a resilient element in a relatively small space. Also, the work of pivoting the cap to the housing can be advantageously separated from the work of assembling pivot-and-latch parts.

Abstract: Disclosed is an improved gaslighter structure which has a detachable support piece to be fitted in the cap and the housing for pivotally fixing the cap to the housing. This arrangement permits complete pivotal connection of the cap to the housing simply by thrusting the upper extension of the support piece into the rear end space of the cap and by thrusting the lower end of the support piece into the rear top inside of the housing until its opposite pivot pins are fitted in the counter sinks on the rear top inside of the housing.

Abstract: Tabletop gaslighter the parts are designed to facilitate the full automatic assembly of these parts into tabletop gaslighters. Parts can be put on each other in a predetermined order, and can be fixedly combined without using screws. The gas lighter comprises a casing, a gas cell having a flame valve fixed to one side of the gas cell and a longitudinal hole made at the other side of the gas cell, a hollow bracket to be clicked to the top of the gas cell with associated catch, supporting a flame adjusting ring and a valve operating lever, a piezoelectric unit to be inserted in the longitudinal hole of the gas cell, and a top closure to be fixed to the casing with associated catch to prevent the bracket, gas cell and other parts from slipping off from the casing.

Abstract: Piezoelectric lighter equipped with a rotatable hook-shaped safety lock is composed of a shank, a finger catch fixed to one end of the shank, a pivot fixed to the other end of the shank, a catch plate fixed to the pivot at the side opposite to the shank and extending substantially perpendicular to the shank, the catch plate having a longitudinal size larger than the width of the slot of a push cap which is put on a piezoelectric unit and a lateral size smaller than the width of the slot of the push cap. The safety lock is rotatably fixed on the top raised side of the casing at such a position that the catch plate may prevent the push cap from descending when the safety lock is put in its locking position in which the shank is vertical with the catch plate laid horizontal and at such a position that the catch plate may allow the push cap to descend when the safety lock is put in its unlocking position in which the shank is horizontal with the catch plate laid vertical.

Abstract: Disclosed is an improved aerosol structure whose partition-walls have passages in the vicinity of the bottom of container, thereby permitting its compartments to communicate with each other. In use the liquid under pressure is supplied to the outlet of aerosol from all compartments until they have been completely exhausted. The bottomless aerosol body and bottom closure are made of synthetic resin. Advantageously the bottom closure may be made of a transparent synthetic resin, thereby permitting a check on the remaining amount of liquid in the container.

Abstract: A valve for aerosol container to dispense a given amount of aerosol from an associated aerosol tank, comprising a base solid providing a valve chamber and a valve stem slidably fitted and upwardly biased by a spring in the chamber. An inlet is made on the bottom of the chamber thereby permitting injection of aerosol from the associated aerosol tank. The valve stem provides a longitudinal channel and an outlet communicating the channel with the valve chamber, and a valve head fixed to the bottom end. A valve ring fitted at the upper side of the chamber in air-tight fashion shutting the outlet all the time. Whereby on depression of the valve stem, the valve ring is yieldingly bent for opening the outlet of the valve stem, thereby allowing a predetermined amount of aerosol to flow out of the valve chamber and eject from the longitudinal channel of the valve stem while shutting the inlet on the bottom of the chamber with the valve head of the valve stem.

No extra parts other than flame nozzle metals, conductive rubber gaskets, and insulating shield caps are required for assembling piper lighters.

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.
