Claim 1
Independent Claim
281 words
A lighter comprising: a generally cup-shaped housing having a cap portion sealably secured thereto to define a chamber for gaseous fuel, said cap portion having a first aperture in fluid communication with said chamber through which fuel may be introduced into said chamber, and said cap portion having a second aperture spaced from said first aperture in fluid communication with said chamber; means for preventing the egress of fuel from said chamber through said first aperture; valve means for controlling the egress of fuel from said chamber through said second aperture, said valve means including an expansible generally cup-shaped conduit sealably secured at the open end thereof to said cap portion around said second aperture to form an expansible chamber over said second aperture, said expansible conduit sealing said second aperture only when in a normal unexpanded position, a nozzle in fluid communication with said expansible chamber through said expansible conduit at a point spaced from said second aperture, and means including a hollow tube in fluid communication with said fuel chamber and a sphere nonrotatably mounted therein, said sphere substantially filling said hollow tube to limit the egress of fuel from said fuel chamber through said tube to said expansible chamber; a scraper carried by said cap externally of said chamber; a flint carried by said cap in pressural engagement with said scraper; and lever means carried by said cap portion externally of said chamber for controlling the operation of said valve means, said lever means being connected at one end thereof to said conduit for controlling the expansion thereof to thereby permit the egress of fuel from said fuel chamber into said expansible chamber for egress through said nozzle.
