Abstract
A thermally insulated cooking pot consists of an outer pot and an inner pot. The inner pot is suspended within the outer pot by hanging from the top inner circumferential area of the outer pot with its own top outer circumferential area. The space between the inner and outer pots becomes an insulation cavity. The contact point between the two pots is sealed by a pliable packing ring with an L-shaped cross-section, thereby sealing the insulation cavity. This sealed insulation cavity provides excellent thermal insulation. The packing ring contains a plurality of protrusions on the surface that come into contact with the inner pot to prevent the packing ring from sticking to the inner pot. The gap formed between the packing ring protrusions and the inner pot prevents the inner pot from sticking to the packing ring.
Claims23
A cooking apparatus, comprising:
- an outer pot having a wall and a base, said outer pot having a top inner circumferential area;
- an inner pot having a wall and a base, said inner pot having a top outer circumferential area, said inner pot's circumferential area, or step, is hanging onto said outer pot's top inner circumferential area, thereby forming a single unit;
- said inner pot is in a state of suspension in the outer pot;
- a removable packing ring made of pliable material is positioned between contact areas of said inner pot and said outer pot;
- and a heat insulating cavity is formed between said inner pot and said outer pot,
- whereby said packing ring seals said heat insulating cavity by preventing exterior air from flowing in and out of said heating insulating cavity.

- an inner pot having a wall and a base, said inner pot having a top outer circumferential area, said inner pot's circumferential area, or step, is hanging from a step area of said outer pot's top inner circumferential area, thereby forming a single unit;
- said step areas makes contact with protrusions on said packing ring, not with the complete upper surface of said packing ring,
- said inner pot is in a state of suspension in the outer pot;
- a removable packing ring made of pliable material is positioned between contact areas of said inner pot and said outer pot;
- and a heat insulating cavity is formed between said inner pot and said outer pot,
