ABSTRACT:
A receptacle comprises a plurality of juxtaposed tanks interconnected adjacent upper portions thereof in liquid communication with each other by eyelets defining liquid transmitting passages. Each of the tanks has an open top closed by a funnel shaped cover having a central opening for admitting burning liquid fuel. Spheres are suspended from the covers to normally seal the liquid transmitting passages with the spheres each having a density which will permit them to float on the liquid fuel when it rises to the level of the passage to thereby open the passage.
