A thermally insulated container for storing and serving frozen confectionery items, wherein the container is preferably arranged to be removably mounted within a service cart, such as an inflight service cart.

A robotic delivery vehicle may be capable of providing sufficient insulation for perishable items without sacrificing the delivery robotic delivery vehicles' travel range by using passive cooling configurations. Passive cooling configurations may include improving the insulation performance of the robotic delivery vehicle as well as incorporating cooling elements. The robotic delivery vehicle may include a cargo bay liner and a vehicle lid that covers and encloses a cargo bay from the external environment. The cargo bay liner may include an insulated bottom and at least one insulated wall extending from the insulated bottom, wherein the at least one insulated wall and the insulated bottom define a cargo volume. The lid may define a lid volume and is configured to selectively enclose the cargo volume.
