Abstract
Abstract Dual function of the closing device comprises an outer threaded retainer encasing a valve including a flexible flap which functions in one direction as dispenser and in the other direction as a seal when forced against the valve seat. The threaded retainer is constructed with threads at each end retaining a floating valve. The device is constructed and arranged to function as a dispenser when secured to a tube at one end and as a closure or seal when secured at the opposite end.
