An insulated container and cover construction comprises an outer container shell (24) terminating in an opening (26) having a surrounding edge (28), an inner container shell (30) nested within the outer container shell (24) and having an opening (32) surrounded by a continuous edge (34) in abutment with the surrounding edge (26). The inner container shell (30) is otherwise spaced inwardly and generally out of contact with the outer container shell (24). A cover mounting assembly 49, 52 is mounted on the outer container shell 24 adjacent the opening 26. A single seal ring (38) of elastomeric material has a first sealing surface (42) disposed at the interface of the shells 24, 30 and the cover mounting assembly 49, 52 to seal the same and a second inwardly facing sealing surface (48) overlies the opening (32) of the inner container shell (30). Locating rings (49), (52) define the cover mounting assembly and locate the single sealing ring (38) on the inner and outer container shells (24) and (30) and a cover (12) is removably mounted on the container and has a sealing surface (70) in sealing engagement with the second sealing surface (48) on the sealing ring (38).
