Abstract
A transportable, sealable container, for example a SMIF pod, including a box and box door. The box has a first sealing surface and the box door has a second sealing surface. The two sealing surfaces form a seal when the box door is moved in a sealing position with respect to the box. A latch mechanism is provided in the box door for holding the box door in the sealing position. The container further includes a breather assembly having an aperture, with a filter, that allows gas to flow between the interior of the container and an environment external to the container. A valve, which is actuated by the latch, opens and closes the aperture. When the latch unlocks the box door, the valve opens the aperture. When the door is locked, the valve closes the aperture.
