Abstract

A cartridge for use in a showerhead or tap is designed for dispensing a liquid, in particular water or a water-based mixture. The cartridge comprises a set of at least two nozzles arranged to create colliding jets of the liquid and thereby create a spray of droplets of the liquid, and a spray shaper for guiding the spray. An inner diameter of the nozzles is between 0.8 and 1.5 millimetres, and a throat of each of the nozzles, along which the nozzle has a constant diameter, has a length that is at least three times this inner diameter.
