Abstract
A pocket lighter capable of providing a vividly colored or scent modified flame basically includes a fluid containment portion, a fuel combustion portion, a valve unit and an igniter. The fluid containment portion has a first compartment containing pressurized fuel, a second compartment containing flame colorant or scenting liquid, and lines for conducting fuel from the first compartment to the fuel combustion portion and for conducting modification liquid from the second compartment to the fuel combustion portion via the valve unit. In preferred embodiments, the second compartment is a flexible bag enveloped by the first compartment and immersed in the pressurized fuel.
Claims6
A pocket lighter capable of providing a colored flame visible in daylight which comprises:
- a fluid containment portion, a fuel combustion portion, valve means and igniter means,
- said fluid containment portion comprising:
- a first compartment containing pressurized fuel,
- a second compartment containing flame coloration liquid,
- a first tubular member for conducting fuel from said first compartment to said fuel combustion portion via said valve means,
- a second tubular member for conducting coloration liquid from said second compartment to said fuel combustion portion via said valve means,
- said fuel combustion portion comprising:
- a burner unit connected to said first tubular member,
- a nozzle connected to said second tubular member positioned to dispense coloration liquid into a flame emitted by said burner unit,
- a heat activated valve associated with said nozzle to control the dispensing of said coloration liquid therefrom,
- said valve means comprising:
- a first valve that controls flow of fuel through said first tubular member and
- a second valve that controls flow of liquid through said second tubular member,
- said first and second valves being arranged to simultaneously open and close,
- said igniter means being positioned in said fuel combustion portion to ignite fuel delivered to said burner unit upon the opening of said first valve.
