Abstract
A bag valve coupling member for a soft drink syrup bag-in-box container having a back-flow preventing one-way valve therein, preferably in addition to the standard self-sealing poppet valve that is biased closed and that is opened when a hose connector coupling member is attached to the bag valve coupling member. The one-way valve prevents back-filling (reuse) of the bag and syrup substitution.
