Claims

[Scope of utility model registration request]

Above the body, there is a neck having a smaller diameter than the body and an appropriate length, the neck and body have an appropriate slope part, and an outer container is formed on the outside of the continuously formed inner container with a bottom. In a metal vacuum container in which the inner and outer containers are kept at a predetermined distance and a vacuum layer is formed, convex ribs 7 are provided above and below in the circumferential direction of the vacuum surface 2' of the body 2 of the inner container 1. Wrap aluminum foil 13 around the vacuum surface 2' to attach the neck part 3 and slope part 4,
An external force that exceeds the elastic limit of the aluminum foil 13 is applied to the body 2 and bottom 5 from the outer circumferential direction, and the neck 3, slope 4, bottom 5, and ribs 7 of the body 2 of the inner container 1 are A metal vacuum container characterized in that an aluminum foil 13 is crimped onto a top part 14, and a concave surface 15 formed between upper and lower ribs 7 of a body part 2 and the aluminum foil 13 have an appropriate interval.
