Abstract: A lunch box assembly having a main housing having a lid rotatably, hingedly attached to a base to provide access to an opened interior of one or more compartments is disclosed. The lid can have ferrously magnetic material and recesses to accept magnets. The magnets can be shaped to fit the recesses. The base can have compartments aligned with corresponding compartments in the lid. The base and the lid can form one or more closed food storage compartments that separate the contents from the neighboring compartments. A latch on the base and lid can produce a clamping force on a small lidded container or containers placed in one or more of the compartments. The clamping force can clamp the lidded container closed and prevent leakage of fluids in the container.
