A container includes a sealing system coupled to an interior surface of the container's lid or cover. The sealing system includes a rotatable latch that, when rotated, cooperates with a number of gears to and a cam assembly formed in the lid to actuate a number of arms or links. In one embodiment, some of the arms extend approximately radially from a driven gear and operate to move an engagement member of the sealing assembly into contact with a complementary engagement member coupled to a base portion of the container. This engagement, in turn, compresses a seal or gasket located between the lid portion and the base portion of the container.
