DETAILED DESCRIPTION

[0025] FIG. 1 shows a perspective and a cross section view reflecting the compact assembly of components. The functional design of this invention is confined to be within the conventional size mess kit, which ranges from 7.0+/1.0 in diameter and 2.75+/1.0 in height. The lid is secured to the base using a unique method of interlocking handles;

[0026] FIG. 2 shows an exploded view of the main components, which can assemble inside the cooking system. The Liquid Fuel burner and gas burner are interchangeable within the assembly area allotted for a burner;

[0027] FIG. 3 reflects the Stoves unique functional method of integrating various fuel sources, which includes solid fuel, liquid fuel, and gas fuel. Based on the size of opening and retention methodology this apparatus accepts not only the components provided, but also various other burners on the market;

[0028] FIG. 4 reflects some of the various unique ways in which the apparatus can be configured for cooking. The Cook Top provides a method to cradle an angled cup with a Cook Top Insert. By allowing the angled cup to rest in a cradled position, it reduces the ability for the cup to tip over and it positions the cup at an optimum height above the flame to maximize the heat distribution. When utilizing either the Exterior Pot/Base or Interior Pot the Cook Top surface is covered creating a new dynamic heat distribution to occur. Since the heat can no longer escape upward through the Cook Top surface it now is required to escape through the provided exhaust holes, which are placed at optimal locations to maximize heat distribution and minimize external environmental influence on the heat source.

[0029] Another unique functional feature of this design is the integration of the Stove to the Interior Pot. The interior Pot can act as a platform in order to eliminate tipping due to various surface conditions, as well as, and secondary heating area. When utilizing the Liquid Fuel Burner as a fuel source, items placed in the Interior Pot will be heated by the radiant or conductive heat provided by the Liquid Fuel Burner. For example, if water were placed in the Interior Pot the water would be heated from the heat transferred by the Liquid Fuel Burner while in use.

[0030] FIG. 5 reflects some of the unique functional features associated to the Stove, Cook Top, Interior Pot, and Liquid Fuel Burner. In the cross-section view one can visually see how the angled Cup is cradled in the Cook Top and how the Cup is seated closer to the heat source. Based on the location of the heat source and heat escaping along the side of the Cup this configuration maximizes the heat distribution around the Cup.

[0031] However, when utilizing one of the Pots note how the heats escape route is changed. The heat is now forced to travel out the side exhaust holes, thus maximizing the heat distribution to the bottom of the Pot. It is important to note the functional design of the airflow intake and exhaust. The slotted mouth type opening provides a uniform stream of air intake, while the exhaust holes are positioned slightly below the Cook Top requiring the heat to distribute over the base of the Pot before escaping. With the air intake and exhaust positioned at 180 the rest of the wall operates as a windscreen allowing the user to turn the stove in a direction that best controls any negative outside environmental influence.

[0032] It is important to note that Liquid Fuel Burners become very hot while in use. To harness this untapped resource of heat, the user can place items inside the Interior Pot while being it is used as a Stove platform in order to utilize the radiant heat of the Liquid Fuel Burner. One of the most functional uses would be the heating of water for cleaning after cooking or for bathing. The side benefit of placing water in the Interior Pot provides for a more rapid removal and storage of the Liquid Fuel Burner after use.

[0033] FIG. 6 reflects on how the Burner Retention methodology works. In considering the functionality of this method, it was of critical importance to overcome form, fit, and function. With limited space and items that can cause interference, it required analyzing the functional size and requirements for each type of fuel source. The functional solution is based on several factors: First, the retention method has to be based on capturing the fuel source on threads, grooves, divots, and outside diameters. Secondly, the retention method would need to be driven by spring, clip, screw, cable, or pneumatic means. Third, the Stove opening must be sufficient enough to allow the object to enter, be captured, and retain securely. Fourth, the retention method must have sufficient range of motion to capture a variety of fuel sources currently on the market. The method depicted utilizes a spring-loaded horseshoe shaped retention clip to capture around the outside threads of the Liquid Fuel Burner, an exterior groove of the Gas Burner, and the base of the Solid Fuel Insert.

[0034] FIG. 7) is an exploded view of the Liquid Fuel Burner provided with this cooking system. This Liquid Fuel Burner provides a unique approach to utilizing a fuel medium, which assists in controlling fuel leaks, spills, and rapid fuel consumption. In utilizing a fuel medium, the issue focuses around safety concerns by converting a liquid fuel into a fuel paste. In this case, the Liquid Fuel Medium used is Food Grade Diatomaceous Earth based on its use for hydroponics, thermal, and absorption capabilities, as well as, the products safety considerations. Compared to liquid fuel the fuel paste tends to have a more controlled burn.

[0035] The important ingredient to the Liquid Fuel Burner is the Fuel Canister Insert. The functional design of this insert allows for all of the liquid fuel to be drawn from the medium up to the burn area without allowing flames to reach the outer walls and canister lip area. The holes in the Fuel Canister Insert are located down far enough that the medium or Diatomaceous Earth in this case to continuously cover the holes, thus preventing any flame from reaching the outer walls or canister lip.
