Abstract
Drop dispenser for releasing a pharmaceutical liquid in drop form, with a housing, a liquid storage and a discharge opening, which penetrates a wall of the housing and to which an outlet valve is assigned, for extracting the liquid. The discharge opening is surrounded by a drop-formation area on the outside of the housing, wherein this drop-formation area, at least in an outer region with respect to an alignment of the drop dispenser with the discharge opening pointing vertically downwards, has a shape tapering downwards and towards the discharge opening. The drop dispenser allows the release of drops with a constant size and shortens drying time.
