Abstract
A heat insulating cooking vessel includes a heat insulating outer container, an inner container which is releasably housed in the outer container, and a heat insulating lid member for closing the opening portion of the outer container when the inner container is housed in the outer container. The inner container is formed shallower than the outer container so that the inner container is positioned below the opening portion of the outer container when housed in the outer container. The side wall of the inner container has at least one handle, each handle being composed of a tang portion extending upward and a grip portion arranged on the tip of the tang portion. The heat insulating lid member of the outer container has at least one cutout into by which the handle of the inner container can be inserted. The heat insulating lid member is releasably disposed to the opening portion of the outer container so that a lower face of the heat insulating lid member is positioned adjacent to the opening portion of the inner container and below the opening portion of the outer container.
