ABSTRACT:
A thermal fluid receptacle, e.g., a vacuum flask, comprises a complete unit which is subdivided into a main fluid container A and a cup compartment B. Fluid from the main container may pass into the cup compartment by depressing a switch H and subsequently opening a stopper G between the main fluid container and the cup compartment. Another switch J located on the cup operates a stopper F on the top of the cup compartment allowing fluid in the cup to be accessed via an aperture E. Thus, the above receptacle enables fluid to be moved from one compartment, which may be heated, cooled, or enclosed by a vacuum, to another compartment all within the same receptacle.
