Collapsible combustion container devices
Collapsible combustion containers are disclosed and described. Such combustion containers generally include a plurality of vertically oriented panels joined by hinges. The hinges include hinge pins that can be configured to form at least part of a base that supports the container or at least part of a heating platform above the container or both. Further, the panels can contain one or more fuel openings which allow a user to control placement of fuel in the container inserted from each opening so as to select a point inside the container where the fuel will converge and combust.
