Abstract

Abstract An improvement is provided in a disposable lighter having a fuel receptacle, a pyrophoric sparking wheel lighting mechanism mounted on the top edge thereof, and a finger-actuated fuel-control valve adjacent the sparking wheel. The improvement is provided by a windshield of similar cross-section to that of the receptacle and slidably retained between upper and lower stop members on the receptacle, the windshield comprising two solid side walls, a solid back wall, an open top and an open front wall the solid side walls having a thumb-access cut-away portion, the open front wall having a cigarette-access opening above the cut-away portion of the side walls, the windshield being between about 50% and about 100% and preferably about 100% of the height of the receptacle. This provides a screen to enable the lighter to be lit even in strong winds.
