Food and beverage storage and serving vessel comprising an integral phase change material

A food and beverage storage and serving vessel includes an inner container, an outer container, and a removable lid. The outer container has a hollow chamber that extends through a bottom wall and a side wall of the outer container. The chamber is filled with a phase change material that stays cold for an extended period of time when chilled, or stays hot for an extended period of time when heated. The inner container is removably assembled into the outer container, where surface contact between the inner container and outer container transfers the cold/heat of the phase change material to a food or beverage contained in the inner container.
