Abstract
Official abstract text for this publication.
In a vacuum insulating container, an outer cylinder has a first annular wall that extends radially inward so as to be inclined with respect to an aperture plane of the outer cylinder at an open end of the outer cylinder and has a tip end part spaced apart from an outer peripheral surface of the inner cylinder; an inner cylinder has a second annular wall that extends radially outward so as to be inclined with respect to the aperture plane of the inner cylinder at an open end of the inner cylinder and faces the first annular wall; and an annular sealing member formed of an elastic body having a low thermal conductivity is compressed between the first annular wall and the second annular wall.
First claim
Opening claim text (preview).
What is claimed is: 1. A vacuum insulating container comprising: an outer cylinder having a bottom; and an inner cylinder having a bottom, the inner cylinder being disposed in the outer cylinder, and a vacuum space being formed between the outer cylinder and the inner cylinder, wherein the inner cylinder is disposed with respect to the outer cylinder in such a manner that an aperture plane of the inner cylinder is located outside of an aperture plane of the outer cylinder, the outer cylinder is provided with a first annular wall that extends radially inward so as to be inclined with respect to the aperture plane of the outer cylinder at an open end of the outer cylinder and has a tip end part spaced apart from an outer peripheral surface of the inner cylinder, the inner cylinder is provided with a second annular wall that extends radially outward so as to be inclined with respect to the aperture plane of the inner cylinder at an open end of the inner cylinder and faces the first annular wall, and the vacuum insulating container further comprises an annular sealing member formed of an elastic body having a thermal conductivity lower than that of the outer cylinder and the inner cylinder, the annular sealing member being compressed between the first annular wall and the second annular wall to seal the vacuum space. 2. The vacuum insulating container according to claim 1 , wherein the second annular wall is formed so as to be parallel to the first annular wall. 3. The vacuum insulating container according to claim 1 , wherein the sealing member is provided with a surface that faces the first annular wall and is parallel to the first annular wall, and a surface that faces the second annular wall and is parallel to the second annular wall.
