| 摘要 |
A composite metal sheet cooking utensil such as a cooking pot or frying pan comprises a core 10 of a metal having relatively good heat conductivity such as aluminum, copper, common quality steel etc., coated on one or both sides with a relatively thin layer such as 11 of a more corrosion resistive metallic material such as stainless steel, titanium etc., the layers being bonded to one another across the bottom surface of the cooking utensil and some distance upwardly the lower portion of the cooking utensil wall. The space 20 in the side wall is filled with a gas such as air. An inner layer 12 similar to layer 11 may be provided. A folded beam 13 applied with adhesive may connect the top edge portions of the utensil. The cooking utensil is manufactured by deep drawing a laminated circular blank and the layers can be soldered together where appropriate before or after deep drawing to provide a lamination. <IMAGE> |
