Abstract
A double-layer vacuum container includes: an inner container having a bridging member supported by an outer container in a bridging manner; the outer container through which the bridging member extending from the inner container is externally exposed; and a cover member for externally covering the portion of the outer container through which the bridging member is exposed and for sealing a space inside the cover member and a space between the inner container and the outer container in a vacuum state between the cover member and the outer container. With such a structure of the double-layer vacuum container, the inner container other than a lip is supported by the outer container with a good heat retaining property to prevent the displacement or damage of the inner container.
