Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 187 words
An automatic gas fuelled lighter comprising an outer casing having a base and provided with a gas escape orifice, a fuel container-ignition mechanism unit comprising an expansion valve and slidably guided by and in said casing between a rest position in which part of said fuel container protrudes from said casing and said orifice is displaced relative to the longitudinal axis of said expansion valve, and a working position in which a larger portion of said unit is received within said casing and said orifice is coaxial with said axis of said valve, an operating arm mounted on said unit for movement from a first position to a second position relative to said unit and engaging said ignition mechanism to actuate said mechanism as said operating arm moves to said second position, and resilient means biassing said operating arm toward said first position, said operating arm being positioned to be driven from said first position to said second position by said base against the resistance of said resilient means as said unit is moved from said rest position to said operative position relative to said outer casing.
Claim 2
Dependent Claim 187 words
An automatic gas fuelled lighter comprising an outer casing having a base and provided with a gas escape orifice, a fuel container-ignition mechanism unit comprising an expansion valve and slidably guided by and in said casing between a rest position in which part of said fuel container protrudes from said casing and said orifice is displaced relative to the longitudinal axis of said expansion valve, and a working position in which a larger portion of said unit is received within said casing and said orifice is coaxial with said axis of said valve, an operating arm mounted on said unit for movement from a first position to a second position relative to said unit and engaging said ignition mechanism to actuate said mechanism as said operating arm moves to said second position, and resilient means biassing said operating arm toward said first position, said operating arm being positioned to be driven from said first position to said second position by said base against the resistance of said resilient means as said unit is moved from said rest position to said operative position relative to said outer casing.
Claim 3
Dependent Claim 37 words
A gas fuelled lighter as claimed in claim 1 wherein said outer casing and said unit are provided with asymmetrical guide means preventing assembly of said unit and casing in an inoperative position relative to each other.
