Abstract
A cooking fuel can closure is provided wherein at least one aperture is defined through the upper surface of the can and a peelable seal such as a thin metal foil is secured by, for example, adhesive to the upper surface of the can peripherally of the opening through the can. Further, a plurality of peripheral openings can be defined about a central aperture in the can so as to facilitate flow of oxygen to the burning fuel thereby using less fuel while still obtaining the same or better burn efficiency of the cooking fuel. Finally, a wick element can be provided centrally of the cooking can closure in a concave portion which is peripherally sealed prior to use by a peelable seal so as to prevent leakage therethrough.
