A single-piece seamless construction container formed from a thermoformable material, the container including a vessel, at least one wing, and at least one hinge coupling the wing to the vessel. The wings comprise a patterned surface, although only the vessel, or the wings and the vessel may also be configured to include a patterned surface. The wings are configured to wrap about the container with the patterned surface serving to trap air between an outer surface of the vessel and an inner surface of the wing. The trapped air and the wing forms an insulative air gap between a surface of the container and the wing. The container may be nestably stacked in a wing open or wing closed position.
