BACKGROUND OF THE INVENTION The portable heater-cooker of the invention provides a convenient unit which is ideally suited for hunting,

fishing or camping trips, in that it can conveniently and,

easily be used for heating and/or for cooking purposes. The unit is in the form of a closed pail, or bucket, which contains, for example, solid fuel in the form of chemically processed starter charcoal and additional charcoal. The fuel in the unit can be ignited by a match in minutes, and it will burn for several hours.

In the utilization of the unit of the invention, the cover is removed, and legs are bent out from its top surface. The cover is then fitted over the bottom of the container to act as a stand. The solid fuel within the container is then ignited. I

Appropriate spronge rubber packing may be provided at the top of the container to hold the solid fuel in place until the cover is removed. The unit may be encased in polyethylene wrapping, or the like, which is removed only when the unit is to be used. As mentioned above, the unit of the invention is intended to be disposable, and as many as may be required for any particular trip may be taken along the trip.

BRIEF DESCRIPTION OF THE DRAWING FIG. I is a perspective representation of the heatercooker unit of the invention in a closed form; and

FIG. 2 shows the heater-cooker unit of the invention opened and in readiness to perform its intended function.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT face of the cover. However, when the cooker-heater unit is to'be used, the cover is removed, and is snapped over the bottom of the container 10, as shown in FIG.

2. The legs 16 are turned out, as also shown in FIG. 2, so that the cover may form an appropriate stand for the unit.

As shown in FIG. 2, the unit has an upper rim 18 which is intended to support a cooking utensil. Appropriate air holes 20 are formed in the upper rim.

The container is normally filled with solid fuel, such as charcoal 22, and specially treated starter charcoal, so that ignition may be accomplished easily and efficiently.

The entire unit is intended to be disposable. It is purhcased in the form shown in FIG. 1 with the solid fuel contained within the container 10, and packed, as suggested above. The entire unit may be appropriately wrapped, as also suggested above.

At the camp site, the unit is opened, and it may be started easily by a match, and the charcoal will begin burning efficiently within four or five minutes. The solid fuel heat produced by the illustrated unit has no odor, as is the case when liquid fuel is used. The unit will burn, for example, for about four hours under usual conditions, and with intense heat.

It will be appreciated that although a particular embodiment of the invention has been shown and described, modifications may be made. It is intended in the claims to cover the modifications which come within the spirit and scope of the invention.

What is claimed is:

l. A cooker-heater unit comprising: a container having a closed bottom and an open top, and further having an upper rim to serve as a support for a cooking utensil, said upper rim having air holes formed therein;

- a cover for said container having legs formed therein in position to be turned out from the plane of the surface thereof, said cover being adapted to fit over the open top of said container and form an enclosure therefor and being further adapted to fit over the bottom of said container with said legs being turned out from the plane thereof so as to serve as a stand for said container.

2. The cooker-heater unit defined in claim 1, and which includes a wire loop handle pivotally mounted on said container.
