Abstract: A fireproof container is used to store items and prevent fires from damaging the items stored within the fireproof container. If a fire originates from within the fireproof container, the fireproof container may be used to prevent the fire from escaping. The fireproof container includes a receptacle, a lid, and a lip. The receptacle is used for storing objects and includes a base panel and a lateral wall. The lateral wall extends from the base panel and the lid may be positioned onto the lateral wall to cover items stored in the receptacle. The lip extends from the lateral wall and is used to precisely guide the lid onto the receptacle. An intumescent material is incorporated into the receptacle, the lid, and the lip and is used to prevent flames and heat from passing between the inside of the fireproof container and the outside of the fireproof material.
