A foldable container including a sheet of material is laid out in bottom, side, end, foldable gusset, and top panels. The panels are folded to form a seamless container having a lid that is selectively opened and closed by a zipper. The assembly container is essentially waterproof since the only seam is at the zipper. The sheet may be made of thermal insulating material resulting in a container that may be used to carry hot or cold foods and beverages. When not in use, the container may be unfolded and the panels may be refolded into a compact storage mode secured by elastic straps.
