Abstract
Disclosed is a geometric lockout coupler assembly comprising a probe capable of reversibly moving between an open position and a closed position, the open position permitting fluid to pass through the probe; and a bung cup sized and configured to accept the probe. The probe further comprises a geometric configuration which cooperates with the complementarily shaped bung cup to allow fluid to flow through the probe while not permitting other probes to cooperate with the bung cup.
