An insulated container is comprised of an outer shell including a base, a predominantly convex portion, and a predominantly non-convex portion, and an insulating insert positioned in the outer shell. The convex portion and the non-convex portion of the outer shell meet at a seam which is disposed substantially at a transition between convex and non-convex outer surface portions of the outer shell. The outer shell has a lower opening with a first diameter in which the base is removably secured. The insulating insert has a maximum diameter which is less than the first diameter so that the insulating insert is insertable into the outer shell through the lower opening prior to securing the base in the lower opening.

1. An insulated container comprising: an outer shell including a removable base, a predominantly convex portion and a predominantly non-convex portion, said convex portion being a lower section of said outer shell, and said convex portion and said non-convex portion meeting at a seam which is disposed substantially at a transition between convex and non-convex outer surface portions of said outer shell, said outer shell having a lower opening with a first diameter and in which said base is removably secured; and an insulating insert having a convex configuration positioned in said outer shell and having a maximum diameter less than said first diameter so that said insulating insert is insertable into said outer shell through said lower opening prior to securing said base in said lower opening. 2. An insulated container according to one of claim 1; further comprising locking clamp means for clamping said convex and non-convex portions to each other at said seam. 3. An insulated container according to claim 2; wherein said locking clamp means is, in respect to movement of said convex and non-convex portions relative to each other, a non-detachable locking clamp. 4. An insulated container according to claim 1; wherein one of said convex and non-convex portions has an encircling projection adjacent said seam and overlapping the other of said convex and non-convex portions for hiding said seam. 5. An insulated container according to one of claims 1 and 2; wherein said base has screw threads and said outer shell has screw threads at said lower opening thereof for mating with said screw threads of said base to secure the latter to said outer shell. 6. An insulated container according to claim 1; in which at least one of said convex and non-convex portions and said base is of a synthetic material. 7. An insulated container according to claim 1; wherein said insulating insert has a pot-bellied configuration with a diameter that increases to a maximum and then decreases.
