Abstract: A bottle stopper with an inlet and outlet fitting that is adapted to receive a pressurized gas to dispense a liquid from the lower portion of a bottle and having a hand grip with a dedicated arch partially conforming to at least one finger. The bottle stopper includes a dispensing mechanism having a receiving structure with at least one sealing rib configured to conform to an inner wall of a dispensing container port when the sealing rib is inserted into the dispensing container port. The receiving structure receives an end portion of a dispensing structure tube having a latching surface located on an outer perimeter of the dispensing structure tube. The primary handle structure is located opposite the secondary handle structure and they each have a dedicated arch partially conforming to a user's fingers for removing or installing the dispensing structure tube into or out of the receiving structure.
