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.

A method of surface treatment and an apparatus used in said surface treatment are provided in the present invention. Said method comprises dipping a surface-to-be-treated of an article in a treating liquid, moving said article in said treating liquid, letting the treating liquid flow in the reverse direction against said moving, spraying the treating liquid on the surface-to-be-treated of the article before and/or during said dipping and gush-spraying the treating liquid on the treated surface after said dipping; and said apparatus comprises a tank filled with a treating liquid, spraying tools arranged above and/or in said treating liquid in the front part of said tank, means of overflow formed in the front end of the tank, a container receiving the treating liquid overflowing from said means, a path recirculating the treating liquid from said container to the tank and a spraying tool arranged in the rear part of the tank.

Method of surface treatment and an apparatus used in said surface

An apparatus used in surface treatment and a method of surface treatment using said apparatus are provided in the present invention. Said apparatus comprises a dipping tank forming one or more hoppers in its bottom, a drain path connected to said hoppers, a solid-liquid separator settled in said drain path, a recirculating path for supernatant from said separator, and a spraying tool connected to said recirculating path and arranged in the rear part of the dipping tank; and said method of surface treatment using said apparatus comprises dipping an article-to-be-treated in a treating liquid in a dipping tank forming one or more hoppers in its bottom, purging sludge formed and settling during said dipping through a drain path connected to said hoppers, separating said sludge by a solid-liquid separator settled in said drain path, recirculating supernatant through a recirculating path from said separator to a spraying tool connected to said recirculating path and arranged in the rear part of dipping tank, and spraying said supernatant from said spraying tool to the treated surface of an article after dipping.
