Abstract

Abstract A vessel has a boundary wall defining a cavity which contains a liquid. A heating insert is in heat-conducting relation with said cavity and defines a heating compartment adjoining said boundary wall and containing a heat-delivering substance which is capable of performing an exothermic reaction. An outer drinking container contains said vessel and insert. Said outer container and vessel consist of a sufficiently heat-resisting material, which consists at least in part of plastics material.
