A bottle assembly including a bottle, a top closure member adapted for releasable engagement with a top portion of the bottle, and a bottom closure member adapted for releasable engagement with a base portion of the bottle. The bottom closure member has a base panel with at least one aperture therein. A diaphragm is positionable between the bottom closure member and the base portion. The diaphragm has at least one sealing element for sealingly engaging the base panel of the bottom closure member and an air passage extending through the at least one sealing element. The diaphragm is moveable between a sealed position and an unsealed position. The air passage is configured to inhibit liquid contained within a liquid chamber of the bottle from entering the air passage when the diaphragm is in its sealed position by trapping air within the air passage.
