Abstract: An extinguishing container kit including a resilient, foldable fireproof cloth having an original extended condition for holding the flammable substance therein. The resiliency of the fireproof cloth permits return to the original extended condition when released from an alternate cinched condition in which a fireproof drawstring woven through the apertures is gathered to cinch the fireproof cloth. An impermeable, fireproof container holds the cinched fireproof cloth, the flammable substance stored therein, and an optional amount of water. A removable lid is disposed on the fireproof container to seal the fireproof container to limit air ingress thereinto to extinguish and cool the flammable substance for subsequent disposal or re-use.
