Description

[Detailed description of the invention] The present invention has a metal vacuum double container with a vacuum between an inner container part and an outer container part, and a handle is connected to a shoulder member attached to the top of the vacuum double container. Regarding the metal thermos flask.

Conventionally, this type of thermos flask often employs a double-supported handle with both ends attached to the outer surface of the container. If a cantilever support type handle is used instead, the mounting strength will be halved compared to a double support type handle.

Moreover, this type of metal thermos has a vacuum double container made of metal such as stainless steel, so it is heavy, so when you grip the handle and lift the thermos to pour liquid, the base of the handle bends a lot. There is a problem in that this part is easily damaged because of the moment acting on it.

The present invention is a metal thermos flask that can sufficiently withstand the above bending moment, and by utilizing the outer shape of the container body, it can provide sufficient mounting strength even with a cantilevered handle without impairing the appearance of the surface-mounted state. The purpose is to provide
