  • Patent number: 5447430
    Abstract: Briefly, the invention comprises a pressurized butane or naphtha lighter with a clear plastic butane or naphtha reservoir. The butane or naphtha is colored by special dyes to lend attractiveness to the device. The use of colored butane or naphtha instead of colored plastic butane or naphtha reservoirs gives the color a dynamically changing aspect. As the transparent lighter case is moved about the colored butane or naphtha flowing within forms a particularly beautiful effect. Butane or naphtha coloring agents and proportions have been developed which allow the creation of a wide range of hues and shades without adversely effecting the flammability of the raw butane or naphtha.
