Abstract: A portable food container includes a first container for receiving a food item and having a first end with an opening, a second end, and a sidewall connecting the first and second ends. A closure of the first container is releasably securable to the opening. A second container has an open configuration and a closed configuration, and defines a first cell for receiving a food item, a second cell for receiving the first container, and a port for receiving a portion of the first container. When the second container is in the closed configuration and the first container is located in the second cell, the first container opening is substantially aligned with the port to receive the closure. The closure secures the second container in the closed configuration when the first container is located in the second cell and the closure is secured to the opening.
