Abstract
An article of cookware is assembled by the riveted attachment of a handle. Novel rivets are first attached from the interior of the cookware article via a flush hole such that the deformation of the cookware article around the rivet locks the rivet to the cookware article yet leaves the rivet head flush with the interior surface of the cookware article. The handle is subsequently attached by deforming the opposite end of the rivet.
