Description

[Detailed Description of the Invention] Technical Field This invention relates to a handle attachment device for a metal vacuum double container, which provides a vacuum insulation space between the inner and outer metal containers.

Prior Art In the case of a double vacuum container made of metal, the handle is attached to the body surface of the outer container that forms the peripheral wall of the container, but if the mounting structure requires screws or rivets to pass through the outer container, it is difficult to maintain the vacuum state between the inner and outer containers. You will lose it. Therefore, when attaching a handle to the barrel surface of the container, conventionally a handle fixture is fixed to the barrel surface by spot welding or the like, and the handle is fixed thereto. On the other hand, as a design effect, polishing the body surface of a metal vessel is also carried out, but in this case, the protrusion of the fixture fixed to the body surface of the vessel obstructs the polishing work of the body surface. , it has become difficult to work with. If you attempt to attach the fixture after polishing the barrel surface to avoid this, it is not practical because you will easily damage the carefully polished barrel surface.

Purpose The purpose of this invention is to provide a handle attachment device for a metal vacuum double container that can eliminate the drawbacks of the conventional method.

Composition/Function This invention is based on the following features: A fixing device is fixed in a recess formed on the outer surface of the instrument body so as not to protrude from the recess, and the handle attachment end is fixed to this fixing device. It is said that

Because the fixing device does not protrude beyond the recess on the body surface,
Fixtures can be provided before polishing the vessel barrel surface. In addition, the handle attachment end fixed thereto can be prevented from spoiling the appearance by covering the inside of the recess or the fixture. Moreover, by fixing the handle attachment end to the recess, the attachment strength can be further improved.
