Optimum application of low-viscosity media
The spray insert is integrated in the closure until the bottle is used for the first time. When unscrewed, the insert presses against the bottle neck opening automatically and precisely. Spray inserts allow very thin fluids to be cleanly dosed, i.e. very low-viscosity media can be applied perfectly without coming into contact with the glass thread.
