Abstract
A method for attaching a planar electrical element (5), such as a thick film printed circuit, to a vessel (1) whereby the element (5) is integrated in the body of the vessel (1) to form a heating apparatus such as an electric kettle. The vessel (1) defines an aperture (4) at a position where the element (5) is to be secured thereto and the element (5) includes a plate capable of covering the aperture (4). The element (5) is retained in position covering the aperture (4) by subsequent deformation of the body of the vessel. In the method, a sealing member (7, 11, 12, 13) is located between the periphery of the aperture (4) and the element (5) and a securing member (6) is positioned on the element (5) on the opposite side to the sealing member (7, 11, 12, 13). The securing member (6) is retained in position, with the element (5) in contact with and compressing the sealing member (7, 11, 12, 13) by a predetermined amount whilst the body of the vessel (1) is deformed, such as by heat forming, in a region (9, 15) around the aperture (4). The element (5) is thereby retained in position with the sealing member (7, 11, 12, 13) under compression.
