Abstract:
1. A collapsible burner comprising a body formed from a flat sheet of flexible material having three parallel fold lines and comprising a sheet of plastic material and first and second metal foil portions bonded onto the sheet of plastic material, whereby: the collapsible burner is adapted to be arranged in a collapsed condition in which the sheet of flexible material is folded along the fold lines so as to be substantially flat, and expanded from the collapsed condition to an expanded condition in which the sheet of flexible material is unfolded so that the second metal foil portions form a raised platform adapted to have fuel to be burned placed thereon; and part of the sheet of flexible material including the first portions of the metal foil forms sidewalls and is arranged to form substantially fireproof inner walls of the burner; wherein the sidewalls, when in the expanded condition, are adapted to extend above at least a portion of the raised platform thereby forming an upper periphery of the burner adapted to support a vessel to be heated above the raised platform which extends between the sidewalls to support combustible fuel for heating the vessel.
