Abstract
Abstract This application discloses a carafe consisting of a body housing an evacuated container for thermally insulating liquids held in the carafe which container is supported at its bottom by the base of the housing. A collar from which depends a plastic liner fitting into the container is threaded onto the housing. The collar is provided with a pouring spout and an integrally formed diametrically opposed handle. A hollow closure fits into the opening of the plastic liner to provide insulating means at that opening and a cap covers the closure and is threaded onto the collar. The cap is provided with a pouring opening which is in alignment with the pouring spout and the handle when the closure is threaded onto the collar so that by tilting the carafe by use of the handle the liquid held therein may pour freely from the carafe.
