<p>A supersonic bath appts. with a casing, esp. with a vessel for denture-cleaning fluid, and with a transformer attached to the vessel for conversion of electrical energy into mechanical supersonic vibrations, has a multi-layer adhesive device between the bottom of the vessel and the transformer. This device has a continuous, electrically insulating film or thin foil, on both sides of which there is a heat-hardened synthetic resin adhesive; these adhesive layers are bonded on one side to the sinulating layer and on the other side to the vessel or the transformer. Rapid denture cleaning is possible. There is a strong permanent bond between the transformer and the vessel. The parts of the appts. with which the user comes into contact are electrically insulated.</p> |
