ABSTRACT:
A thermostatic device is provided which is formed from a cup, into which a bimetallic element is placed, and a generally flat lid which is crimped to the cup-shaped member, a layer of insulation being placed between the cup and lid. At least the ends of the lid are slightly formed to increase the pressure in these areas after crimping, so as to prevent leakage, particularly leakage of insulating materials, into the interior of the thermostatic device.
