Abstract
Abstract A first component of the appliance has a first section an annular wall of which surrounds a chamber within which a heating element is located. A second component includes a cupped face mask which is to be placed against the face of the user and a second section communicating with the interior of the mask via suitable passages, and having an annular fluid-storage absorbent element of porous material. The sections are telescoped together and can be axially separated, for facilitating access to the fluid-storage element and heating means.
