This invention relates to cigarette lighters of the type
Referring now to the drawings and to FIGURES 1,
as a fuel (or “gas” lighters as they are commonly known)

reason for the increased popularity of these lighters is

Cigarette lighters using a combustible hydrocarbon gas
require a fuel feeding wick as is the case with the old

be used for several months of normal operation without
