Hermetic closing for glass bottles with 18 mm thread
The dropper is automatically inserted when the cap is screwed into place. The cap should be pushed down and turned until the dropper cap is inserted into the mouth of the bottle. The cap has the shape of the dropper nozzle inside, which ensures that the closure of the cap is watertight for glass bottles with 18 mm or DIN18 threads.
We have different models and finishes of closures for glass bottles with 18 mm and DIN18 threads, in particular caps with dropper caps with two outlet hole diameters: standard hole of 0.7 mm in diameter for liquids in general and hole of 1.6 mm in diameter is specific for liquids with higher viscosity such as oil.
