Abstract: A container assembly and method for constructing a container assembly is provided. The container assembly includes a base assembly, a tray assembly, and a cooling passage cover wall. The base assembly includes a base wall and a base sidewall, the base wall and the base sidewall together forming a base interior volume at which the tray assembly is positionable. The tray assembly includes a tray base wall and a tray sidewall, the tray base wall and the tray sidewall together forming a tray interior volume. A cooling passage is formed between the tray sidewall and the base sidewall. The cooling passage cover wall is removably positionable to extend between the tray sidewall and the base sidewall over the cooling passage. An opening extends through the tray sidewall, the opening providing fluid communication between the cooling passage and the tray interior volume.
