The present invention provides a container having a carton and a cover
sized to fit over and enclose an interior space of the container. Carton
and cover each are adapted to permit controlled flow of air in to and out
of the interior space of the container. In a preferred embodiment of the
present invention, cover sidewalls are adapted to move between an open
position and a closed position, wherein air is permitted to flow in to
and out of the interior space of the container when the sidewalls are in
an open position, but inhibited from flowing in to and out of the
container when the sidewalls are in a closed position.
