Abstract

The present invention relates to a drop dispenser (1), comprising: —a container part (1B) with an interior volume adapted to be partially filled with a liquid phase (2) and a gaseous phase (3) filling the remainder of the interior volume at ambient pressure, the container part (1B) having a displaceable section (1C), and —a dropper part (1A) in physical connection and in fluid communication with the interior volume of the container part (1B), comprising an outflow channel (5), connecting the interior volume of the container part (1B) to the environment; wherein the outflow channel (5) comprises —a first section (5a) having a proximal end (5ap) and a distal end (5ad), each end having the same or different inner diameter selected independently from each other in the range of 0.09 to 0.19 mm; and —a second section (5b) having a proximal end (5bp) and a distal end (5bd); the proximal end (5bp) having an inner diameter in the range of 1 to 3 mm; the distal end (5bd) having an inner diameter in the range of 0.1 to 3 mm, with the proviso that the inner diameter at the distal end of the second section (5bd) is larger than the inner diameter at the proximal end of the first section (5ap); and wherein —the first section (5a) of the outflow channel (5) is generated by laser drilling.
