The plate is arranged within the box member. When the cooler assembly is in a closed configuration, the box member, first and second door members, and the lid define a main chamber, at least portion of a front chamber portion of the main chamber is defined by the first and second doors, the partition, and the lid, at least a portion of a rear chamber portion of the main chamber is defined by the box, the partition, and the lid, and a port is formed between the plate and the lid to allow air flow between the front chamber portion and the rear portion. The coolant material is arranged within the rear chamber portion.
