Disposable liquid fuel burner

摘要

A disposable liquid fuel burner is disclosed which comprises a container having a closed bottom, an enclosing sidewall and an open top and at least partially filled with a liquid fuel. A flat support member is supported adjacent the open top above the liquid fuel and having a centrally located opening receiving one end of an elongated wick of a fibrous material overlying the support member and having its other end immersed in the liquid. The support member may be a cardboard or plastic disk supported on legs or a cylinder or may be a cup-shaped member. A fibrous bat of a refractory, non-combustible material substantially fills the open top and overlies the support member and the end of the wick supported thereon. A bat of a plastic, e.g., polyurethane, foam material overlies the fibrous bat. A top cover is secured on the container closing the open top and is at least partially removable, e.g. removable cover or pull-tap opening cover, to expose the plastic foam bat, whereby the burner may be ignited with the flame extending substantially uniformly from said entire top opening and continuing to burn until extinguished or said liquid fuel is exhausted. The plastic foam bat is combustible and burns off in use with the flame being subsequently emitted from the surface of said fibrous bat. A flat disc or ring member with an opening smaller than the lid is provided to control the size of the flame and rate of burning.
