ABSTRACT:
An improved bottom structure for multi-ply impact bonded bottom cookware is disclosed. The bottom structure with an aluminum ply has a stainless capsule that capsules the edge portion of the aluminum ply to compensate for the thermal brittleness of the aluminum ply, thereby preventing the edge portion of the aluminum ply from being cracked or broken due to the thermal brittleness. The capsule also joins the ends of a net member to the aluminum ply to integrate the net member with the aluminum ply and covers the edge portion of the aluminum ply to provide an improved appearance of the cookware. The stainless capsule effectively guides heat to the central portion of the bottom and causes the bottom to be uniformly heated, thereby preventing the food inside the bottom corner from getting partially scorched about and sticking to the interior of the bottom corner.
