PROBLEM TO BE SOLVED: To ensure easy ignition and boiling even under the strong wind in the extremes of cold weather in a mountain of the winter or cold seasons. SOLUTION: Deep grooves of a rectangular shape connected to a deep groove of a circular shape are radially formed within a tray. For example, the entire volume of the deep grooves is specified to 20 ml which is the amount of methanol necessary for boiling 200 ml water. Next, the shallow grooves of a large circular shape and the shallow grooves of a rectangular shape having a large width are radially formed. The volume of these shallow grooves is also specified to 20 ml. The boiling of the hot water of 400 ml is made possible by these grooves coupled with the deep grooves. An invertable ring is annexed to the side wall of the tray to prevent scorching of a floor plate, etc., during combustion. When the ring is inverted, the ring acts as a handle and this tray is usable as a tableware dish. The combination use with a folding windproof trivet for mountain climbing is possible as well.
