A thermally insulated beverage mug, comprising: a frustro-conical vessel having a hollow chamber for receiving and dispensing liquids, said chamber defined by an inner wall, an outside of said vessel defined by an outer wall, said frustro-conical vessel having a mouth portion defined by a circular rim and having means defining a hollow section disposed between said inner and outer walls for retarding heat conductivity between said inner and outer walls, said hollow section being disposed substantially throughout a body section and a handle section; means defining a circumferential rim disposed on said outer wall of said vessel, below said mouth portion; said handle section connected to said body section of frustro-conical vessel for lifting said vessel; a domed lid disposed over said mouth portion of said vessel in a closed mouth position and being free to move to an open mouth position, said domed lid being articulated for movement about said handle to which it is movably attached; a right-angled hinge disposed between said domed lid and said horizontal handle arm, said hinge having a substantially vertical hinge arm strapped to said horizontal handle arm and a substantially horizontal hinge arm attached to said domed lid, said horizontal hinge arm being rotatively pinned at a hinge funcrum to said vertical hinge arm and having a stop abutment for mating engagement with a limit abutment on said vertical hinge arm, said stop and limit abutments having an open angle of approximately 110 degrees of arc relative to said closed mouth position of said lid; and a thumb actuator disposed in a substantially vertical position directly over said vertical hinge arm and integrally attached to said horizontal hinge arm for rotating said domed lid through the approximately 110 degrees of arc from said closed position to said open position.
