Liquid heating vessels having heated bases

摘要

A liquid heating vessel comprises a vessel body having an opening in the base thereof and an electrically heated base arranged to close the opening. The heated base is secured to the vessel body by means of a clip member (2) which comprises a plurality of radially extending fingers (4). The clip member (2) has an initial configuration in which it is dished in its overall profile and is deformable to an engaging configuration in which its initial dished profile is reduced or reversed so as to increase the radial extent of the fingers (4). The clip member (2) may be used to secure an annular seal (11) between the heated base and the vessel body. Said annular seal has a cross-sectional profile including on the radially inwardly facing surface thereof at least one annular channel (16).
