Abstract: A dual compartment container, such as a drink bottle, including a container body as a primary compartment for receiving and storing matter, having a mouth, a base and a side wall. The sidewall is substantially cylindrical except for a portion of the side wall that is indented into the container body that forms a recess on the outer surface of the container body. The dual compartment container also has an arcuate rotating cover structured and arranged to rotate from an open position, overlying an arcuate portion of the side wall, to a closed position, overlying the recessed portion of the side wall. The auxiliary side compartment is formed in the recess on the outside of the side wall between the side wall and the rotating cover. The rotating cover is guided in its rotation between the open and closed positions by a channel and following member. Preferably, a locking mechanism is included to lock the rotating cover in open and closed positions.
