Patent Images
1. A device for covering a receptacle containing a vaporizable substance subject to temperature control, the device comprising:
- a frame;
a base supported on the frame, the base is configured to be positioned against the receptacle and having means for effecting temperature control of the substance; and
a cover supported on the frame, the cover is configured to be placed over the receptacle for reducing evaporative loss, the cover and the base are pivoted on the frame in opposing positions such that the receptacle can be positioned between the cover and the base, and the base and cover can be pivotally positioned against the bottom and top, respectively, of the receptacle.

Abstract
A heated cover for a receptacle containing a vaporizable substance. The cover is heated to a temperature above the temperature of the substance so as to prevent condensation of vapor evaporated from the substance. A device for placing and removing the cover with respect to the receptacle is designed in connection with a temperature-controlled heating/cooling plate which controls the temperature of the contents of the receptacle.
