VACUUM HEAT-INSULATING CONTAINER
First Claim
1. A vacuum heat-insulating container comprising:
- an outer cylinder having a bottom, andan inner cylinder having a bottom and disposed inside the outer cylinder, whereina vacuum space is formed between the outer cylinder and the inner cylinder,the inner cylinder and the outer cylinder are disposed such that an opening plane of the inner cylinder is located outward of an opening plane of the outer cylinder,the outer cylinder has a first annular wall that extends inwardly along the opening plane of the outer cylinder, and that includes a leading end portion at a distance from an outer circumferential surface of the inner cylinder,the inner cylinder has a second annular wall that extends toward an outside of the inner cylinder along the opening plane of the inner cylinder, and that faces the first annular wall, andthe vacuum heat-insulating container includes an annular sealing member that is made of an elastic body having a coefficient of heat transfer lower than a coefficient of heat transfer of the outer cylinder and a coefficient of heat transfer of the inner cylinder, and that is squeezed between the first annular wall and the second annular wall so as to seal the vacuum space.

Abstract
Provided is a vacuum heat-insulating container including an outer cylinder having a bottom and an inner cylinder having a bottom and disposed inside the outer cylinder, with a vacuum space formed between the outer cylinder and the inner cylinder. The inner cylinder and the outer cylinder are disposed such that an opening plane of the inner cylinder is located outward of an opening plane of the outer cylinder. The outer cylinder has a first annular wall. The inner cylinder has a second annular wall. The vacuum heat-insulating container further includes an annular sealing member that is made of an elastic body having a lower coefficient of heat transfer than the outer cylinder and the inner cylinder, and that is squeezed between the first annular wall and the second annular wall so as to seal the vacuum space.
