US Patent 7287660 Two-compartment container

A two-compartment container has a lid portion and a base portion hingedly connected to one another and openable and closable in the manner of a clamshell. Both the lid portion and the base portion have partitions, which extend from the hinge and which are aligned with one another. When the container is closed, the partitions abut against one another, effectively isolating the two compartments formed in the base portion by its partition from one another. The base portion includes a locking flap which fits into a gap between the partition in the lid portion and its face and seals it to further isolate the two compartments from one another.
