Abstract
A windproof lighter is provided having an inside unit and an exterior case. The inside unit has an interior chamber, a wick, a flint, a flint position apparatus positioned in the interior chamber, a flint wheel, and a chimney. The lighter has a disposable fuel cell containing lighter fuel. The fuel cell is designed to fit within the interior chamber and to not interfere with the flint position apparatus. When the container is to be used in a windproof lighter, it has an opening that receives the wick. The wick extends into the interior chamber and has a component that is larger than the opening so that when the container is properly positioned within the interior chamber, the component secures the container in position and prevents accidental spillage of the lighter fuel.
