ABSTRACT:
A vacuum bottle of the electric heater type includes a body having a tubular outer shell and a tubular inner shell disposed within the outer shell to form a hermetically sealed thermal insulation vacuum space therebetween. A tubular connecting member has an open lower end and an upper end wall having an aperture formed therethrough. The upper end wall of the connecting member is fixedly hermetically secured to a lower surface of a bottom wall of the inner shell with the apertures therein in communication, and the tubular connecting member is fitted in an aperture of a bottom wall of the outer shell and fixedly hermetically secured thereto adjacent to the open lower end thereof to hold the bottom walls of the inner and outer shells in spaced sealed relation to each other. An electric heater is mounted within the inner shell for heating contents of the inner shell. The electric heater has a body part of which extends downwardly through the aperture in the bottom wall of the inner shell in sealed relationship therewith and the aperture in the upper end wall of the tubular connecting member. The aperture in the upper wall of the connecting member is greater than that of the inner shell bottom wall to accommodate any misalignment therebetween.
