A vacuum is pulled in the insulating space (26) and an access opening (34) is provided at the top of the outer container. A plastic ring (30) is mounted on the outer container about the access opening (34) and has a shoulder section (34) overlying the top of the outer container and a downwardly extending sleeve section (32) integral with the shoulder section and embracing the outer wall (22). An inner container (12) formed of a material selected from the group consisting of glass, plastic and ceramics is nested within the outer container (10) through the access opening and has an open top (16) extending out of the access opening and an outer surface contacting the ring (30).
