<p>A metal disc (2) is attached to the lid (1), which is to be enamelled, of a cooking vessel, for example by spot welding (5), lid and metal disc then being enamelled together. The outer edge (2c) of the disc is intended to engage in the internal thread (6b) of the lid handle (3) in the place of a threaded pin. The edge of the metal disc (2) preferably has the form of three wings (2b) which can be adapted to the diameter of the internal thread. <IMAGE></p> |
