Abstract
Abstract A lighter using liquefied gas as fuel comprising a previously sealed liquefied fuel reservoir, a mechanism adapted to be moved in association with initial igniting operation for unsealing said liquefied fuel reservoir, a vaporized gas reservoir, a gasjetting nozzle communicating with said vaporized gas reservoir, and an ignition member located adjacent said nozzle, wherein said mechanism adapted to be moved in association with initial igniting operation for unsealing said liquefied fuel reservoir establishes a communication between said liquefied fuel reservoir and the vaporized gas reservoir and interrupts this communication by its automatically restoring operation.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
42 words
A lighter according to claim 1, characterized by that a portion of the sealed reservoir full of liquefied fuel is formed as a thin partition and lower end of the movably member opposed to said partition is provided with a pointed end.
Claim 2
Dependent Claim
50 words
A lighter according to claim 1, characterized by thAt the member movable in association with igniting operation is formed as a hollow member through which a bore is drilled out as a communication passage for supplying vaporized gas through a cavity of said hollow member to the vaporized gas reservoir.
Claim 3
Dependent Claim
51 words
A lighter according to claim 1, characterized by that a member for supporting a flint adapted to produce ignition spark in cooperation with a file wheel is slidably provided and one end thereof is formed as a pointed end opposed to the thin partition of sealed reservoir full of liquefied fuel.
Claim 4
Dependent Claim
31 words
A lighter according to claim 1, characterized by that a porous filter is provided transversely to gas passage along a spout of the gas-jetting nozzle so as to adjust gas flow.
Claim 5
Dependent Claim
49 words
A lighter according to claim 1, characterized by that the vaporized gas reservoir and the pit for accommodating the member movable in association with igniting operation are formed above the liquefied gas reservoir and a communication hole provided between said reservoir and pit is provided with a porous filter.
Claim 6
Dependent Claim
51 words
A lighter according to claim 1, characterized by that the vaporized gas reservoir is formed by an upper recess of a lighter body forming the liquefied gas reservoir and an inner lower pit, and that upper periphery of said lighter body is welded integrally to lower periphery of an upper housing.
Claim 7
Dependent Claim
41 words
A lighter according to claim 1, characterized by that the liquefied gas reservoir is formed by a bottomless lighter body having therein a cavity and a bottom member welded to said bottomless lighter body along lower portion of said lighter body.
Claim 8
Dependent Claim
82 words
A lighter according to claim 1, characterized by an upper housing provided with a pit which forms a vaporized gas reservoir and another pit which accommodates a member movable in association with igniting operation, and a coverless liquefied gas reservoir adapted to be welded to said upper housing along lower peripheral edge thereof, wherein a bottom of said pit which accommodates said member movable in association with igniting operation is opposed to a lower pointed end of said member and formed thinner.
Claim 9
Dependent Claim
66 words
A lighter according to claim 1, characterized by that the communication hole between the vaporized gas reservoir and the pit accommodating the member movable in association with igniting operation is the hole obtained by drilling the vaporized gas reservoir through from one side thereof and only the hole provided through one side of the upper housing is sealed with a plug which is fitted thereinto later.
Claim 10
Dependent Claim
59 words
A lighter according to claim 1, characterized by that the member movable in association with igniting operation is formed as a hollow member which is provided at upper part with a gas-jetting nozzle and at lower part with a pointed end, and that the vaporized gas reservoir is located between said nozzle and said pointed end in movable manner.
Claim 11
Dependent Claim
90 words
A lighter according to claim 11, characterized by that a communication hole for establishment of a communication of the pit accommodating the movable vaporized gas reservoir with said movable vaporized gas reservoir is provided for said movable vaporized gas reservoir between said vaporized gas reservoir and the liquefied gas reservoir, said communication hole being normally sealed by a flexible annular packing, and upon depression of said vaporized gas reservoir said liquefied gas reservoir communicates through said communication hole with said vaporized gas reservoir as said flexible annular packing is bent.
Claim 12
Dependent Claim
50 words
A lighter according to claim 1, characterized by that a member for supporting the file wheel is operatively associated with the movable vaporized gas reservoir whereby said movable vaporized gas reservoir is moved by depressing force applied on said file wheel which is transmitted to said movable vaporized gas reservoir.
Claim 13
Dependent Claim
51 words
A lighter according to claim 13, characterized by that the upper housing located above the liquefied gas reservoir is provided with two pits one of which accommodates a flint adapted to produce a spark in cooperation with the file wheel and the other of which accommodates the movable vaporized gas reservoir.
Claim 14
Dependent Claim
86 words
A lighter according to claim 1, characterized by that the upper housing located above the liquefied gas reservoir is provided with three pits, the first of which accommodates a flint adapted to produce a spark in cooperation with the file wheel, the second of which accommodates an operative lever movable in association with igniting operation, and the third of which is formed as a vaporized gas reservoir, and a communication hole is provided between said pit for accommodating said operative lever and said vaporized gas reservoir.
Claim 15
Dependent Claim
46 words
A lighter according to claim 15, characterized by that the pointed end formed as the lower end of the operative lever and the thin partition opposed thereto permits the initial igniting operation to establish a communication between the liquefied gas reservoir and the vaporized gas reservoir.
Claim 16
Dependent Claim
76 words
A lighter according to claim 15, characterized by that the pit accommodating the operative lever is provided at upper and lower parts with packings, respectively, so as to keep an airtight relation between said operative lever and said pit and said operative lever is provided with an axially elongate groove which is located above the lower packing at nonoperative position of said operative lever and below said lower packing at operative position of said operative lever.
