Claims

[Scope of utility model registration request]

A neck portion having a smaller diameter than the body and an appropriate length is provided above the body, and the neck and body have an appropriate slope portion to form an outer container on the outside of a continuous bottomed inner container. In a metal vacuum container in which a predetermined gap is maintained between the inner and outer containers and a vacuum layer is formed, a plurality of vertical or horizontal ribs 7 or a plurality of protrusions 8 are provided on the vacuum surface 2a of the body 2 of the inner container 1. The vacuum surface 2a is wrapped with aluminum foil 13, and the neck portion 3 is
Then, an external force exceeding the elastic limit of the aluminum foil 13 is applied to the slope portion 4, body portion 2, and bottom portion 5 from the outer circumferential direction, and the uneven convex portions 14 and concave portions 15 of the inner container 1, body portion 2 are formed by the plasticity of the aluminum foil 13 alone. A metal vacuum container characterized in that appropriate intervals are provided between the aluminum foils 13.
