Stand-alone self-supporting disposable baking containers and methods of manufacture
View Patent ↗A self-supporting baking mold that includes a base member having a fanciful shape with a perimeter that is more complex than a simple circle and a depending sidewall coupled to said base member. The baking mold is sufficiently rigid to support a quantity of batter without being disposed in a muffin pan or other external supporting structure.
1. A self-supporting baking mold comprising:
a fancifully shaped base member;
a depending sidewall coupled to said base member; and
wherein the base member and sidewall form a semi-rigid structure, wherein the base member and the sidewall comprise metal, and wherein the metal is between 0.00045 and 0.0015 inch thick.
2. The self-supporting baking mold of claim 1 wherein, said base member and said sidewall are made from a unitary piece of material.
3. The self-supporting baking mold of claim 1 wherein, said base member and said sidewall are structured to be peeled away from the finished product.
4. The self-supporting baking mold of claim 1 wherein, said base member and said sidewall are made from aluminum.
5. The self-supporting baking mold of claim 4 wherein said aluminum is coated with a lubricant.
6. The self-supporting baking mold of claim 4 wherein said aluminum is about 0.00098 inch thick.
7. The self-supporting baking mold of claim 1 wherein said base member and sidewall define a cavity having a volume of between about 1 to 12 fluid ounces.
8. The self-supporting baking mold of claim 7 wherein said base member and sidewall define a cavity having a volume of about 3.5 fluid ounces.
9. The self-supporting baking mold of claim 1 wherein said sidewall includes an upper perimeter having a flange.
10. The self-supporting baking mold of claim 9 wherein said flange does not have a curl at the distal edge.
11. The self-supporting baking mold of claim 9 wherein said flange has a length of between about 1/32 and ½inch.
12. The self-supporting baking mold of claim 11 wherein said flange has a length of about ¼inch.
13. A method of making a self-supporting, fanciful shaped baking mold using a die and a punch, said die having a cavity with a fanciful shaped die base wall and a correspondingly shaped die sidewall, said punch corresponding to the shape of said cavity, said method comprising:
placing a sheet of aluminum foil in said die, wherein the aluminum foil is between 0.00045 and 0.0015 inch thick, said foil sheet having a shape approximating the shape of the finished self-supporting shaped baking mold; and
moving said punch into said die cavity thereby deforming said foil sheet, thereby creating a self-supporting baking mold having a fanciful shape.
14. The method of claim 13 wherein said self-supporting shaped baking mold has a wrinkle wall finish.
15. The method of claim 13 wherein said die cavity and said punch include a flange portion, said flange portion extending in a plane generally parallel to the die base wall.
16. The method of claim 13 wherein said step of moving said punch into said die cavity thereby deforming said foil sheet, thereby creating a self-supporting shaped baking mold having a fanciful shape does not include the step of curling the flange.
