DROP DISPENSING WITH INSERT FOR OPTIMIZING THE DOSING PRECISION OF LIQUIDS

摘要

The container (9) comprises a drop dispenser (3) with an insert element (1). The insert element (1) has a lateral notch (6), a transversal notch (7) and a central bore (8). When the liquid in the container (9) is pressurized it passes through the notches (6, 7) to bore (8) and into a delivery passage (12). The notches (6, 7) form a throttling passage (11). The dispensed liquid volume per time does not largely depend on how much the con-Tania is pressurized. The drop dispenser is easy to use. Manufacturing the drop dispenser is not complicated and is possible at a low price.
