ABSTRACT:
A disposable fuel burner 10 is disclosed which comprises a container 11 having a closed bottom wall 12, an enclosing sidewall 13 and an open top 14, and at least partially filled with a liquid fuel 15. A support member 16 is supported adjacent the open top 14 above the fuel 15, and having a centrally located opening 17 of various diameters for receiving one end of an elongated wick 18 of a fibrous material. The support member 16 may be a cardboard or plastic disk supported on legs 21a, a cylinder 21, or may be a cup-shaped member 30. A first layer of fibrous material 22 substantially fills the open top 14 and overlies the support member and the end of the wick supported thereon and acts as an interface between the fuel 15 and the atmosphere. A second layer of a plastic 23, e.g., polyurethane, foam material overlies the first layer. A top cover 27 is secured on the container 11 closing the open top 14 and is at least partially removable, e.g., removable cover or pull-tab opening cover, to expose the plastic foam layer 23, whereby the burner may be ignited with the flame extending substantially uniformly from said entire top opening 26 and continuing to burn until extinguished or said fuel 15 is exhausted. The plastic foam layer 23 is combustible and burns off in use with the flame being subsequently emitted from the surface of said fibrous layer 22. A flat disc or ring member 124 with an opening 125 smaller than the lid 27a is provided to control the size of the flame and rate of burning.
