Abstract
A tote for transporting refrigerated or frozen goods, e.g., foodstuffs, comprises an insulated container and a coolant insert. The insulated container comprises a durable, impact-resistant shell, an insulation insert, an optional corrugated liner, and a cover. The coolant insert fits within the container such that it rests on the top edge of the insulation liner sidewalls, and it holds a coolant, e.g., carbon dioxide snow. The insert has a perforated bottom wall and an insulated top wall. When the tote holds frozen goods, the perforated bottom wall is opposite the interior of the container. When the tote holds refrigerated goods, the insulated top wall is opposite the interior of the container.
