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. Manual opening of the valve in conjunction with rotation of a wheel at the top of a spark assembly which generates a spark to ignite the gas provides for the flow of gaseous fuel through the valve to sustain the flame.
