A portable stove includes a frusto-conical body and a grid carried within the body together with an optional cooking surface for the smaller end of the body and stands to elevate the larger end of the body to facilitate establishing an air flow into the body. By rolling a flat piece of metal that has folds on both ends until the folded ends are interlocked, the stove's body is formed. Squeezing the formed body releases it to return to a flattened configuration for storage. The components of the stove can thus be stored in a compact configuration such as in a backpack. An optional oven includes a cooking chamber within a housing. The oven rests on the body and redistributes heat from the burning fuel inside the body to the cooking chamber base, body and lid so that it bakes evenly. The housing confines the heat to the chamber for improved cooking efficiency.

A stove for use with a cooking container, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening, wherein said frusto-conical body has an opening formed therein;a fuel support grid carried within said frusto-conical body;a fuel hatch carried by said frusto-coni
1. A stove for use with a cooking container, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening, wherein said frusto-conical body has an opening formed therein;a fuel support grid carried within said frusto-conical body;a fuel hatch carried by said frusto-conical body and positioned above said fuel support grid, said fuel hatch having a closed position wherein said fuel hatch covers said opening in said frusto-conical body and an open position wherein said fuel hatch exposes said opening so said fuel support grid is accessible;support bridges carried by said frusto-conical body at top opening for supporting a cooking container; andmeans for admitting a draft of air into said frusto-conical body so that said draft of air passes through said fuel support grid and out said top opening, said admitting means being adapted to be adjustable to vary the amount of said draft of air admitted,wherein said frusto-conical body has a first edge and an opposing second edge, said first and said second edges being bent into complementary folds that interleave to define said frusto-conical body, said folds being releasable from interleaving when said frusto-conical body is squeezed, without tools, so that said body can be flattened. 2. The stove as recited in claim 1, wherein said admitting means further comprises a collar positioned near said bottom opening and tightened against said frusto-conical body, and having plural openings formed therein and wherein said frusto-conical housing has plural openings formed therein, and wherein said collar is rotatable with respect to said frusto-conical housing so that said openings of said collar can be brought into and moved out of registration with said plural openings of said housing. 3. The stove as recited in claim 1, wherein said housing has plural holes near said bottom opening and said admitting means further comprises plural rods that are dimensioned to be insertable into said holes, said rods being insertable a little more or a little less to adjust said draft of air flowing into said frusto-conical housing. 4. A stove, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening, said frusto-conical body having a first edge and an opposing second edge, said first and said second edges being bent into complementary folds that interleave to define said frusto-conical body, said folds being releasable from interleaving when said frusto-conical body is squeezed, without use of tools, so that said body can be flattened; anda fuel support grid carried within said frusto-conical body. 5. The stove as recited in claim 4, further comprising support bridges carried by said frusto-conical body at said top opening for supporting a cooking container. 6. A stove, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening, said frusto-conical body having an opening formed therein;a fuel support grid carried within said frusto-conical body; anda fuel hatch carried by said frusto-conical body and positioned above said fuel support grid, said fuel hatch having a closed position wherein said fuel hatch covers said opening in said frusto-conical housing and an open position wherein said fuel hatch exposes said opening,wherein said frusto-conical body has a first edge and an opposing second edge, said first and said second edges being bent into complementary folds that interleave to define said frusto-conical body, said folds being releasable from interleaving when said frusto-conical body is squeezed without use of tools so that said body can be flattened. 7. The stove as recited in claim 6, wherein said fuel hatch includes means for propping said fuel hatch in said open position so that fuel can be placed on said fuel support grid. 8. The stove as recited in claim 6, further comprising means for admitting a draft of air into said frusto-conical body so that said draft of air passes through said fuel support grid and out said top opening, said admitting means being adapted to be adjustable to vary the amount of said draft of air admitted. 9. The stove as recited in claim 6, further comprising support bridges carried by said frusto-conical body at said top opening for supporting a cooking container. 10. A stove for use with a cooking container, comprising: a frusto-conical body having a smaller top opening and a larger bottom opening, said body carrying means for supporting a cooking container so that said draft flows between said supporting means and said cooking container when said cooking container is on said supporting means;a collar positioned near bottom opening and tightened against frusto-conical body, said collar having plural openings formed therein and wherein said frusto-conical body has plural openings formed therein, and wherein said collar is rotatable with respect to said frusto-conical body so that said openings of said collar can be brought into and moved out of registration with said plural openings of said frusto-conical body; anda fuel support grid carried within said frusto-conical body,wherein said frusto-conical body has a first edge and an opposing second edge, said first and said second edges being bent into complementary folds that interleave to define said frusto-conical body, said folds being releasable from interleaving when said frusto-conical body is squeezed, without use of tools, so that said body can be flattened. 11. The stove as recited in claim 6, wherein said hatch is adapted to be partially insertable into said opening to remain in said open position until lowered. 12. The stove as recited in claim 10, wherein said supporting means is support bridges. 13.
