Abstract: The invention provides a liquid dispenser for dispensing liquid medicaments, in particular, in metered droplets, in which an upwardly open container (2) can be closed off by means of a deformable diaphragm (3) and liquid is dispensed from the container (2) in the form of droplets through an outlet tube (12) leading out of the interior of the container when slight pressure is exerted on the diaphragm (3), the opening of the outlet tube (12) pointing at the upper surface of the diaphragm (3). This allows an instrument used to exert the pressure on the diaphragm (3), e.g. pincers holding a piece of cotton wool, also to be used at the same time to take up the liquid displaced from the container (2); single-handed operation is thus possible. Any unused liquid cannot run back. The instrument comes into contact only with the diaphragm (3) and the liquid dispensed onto it, and the diaphragm (3) can be exchanged before each re-use, thus satisfying even the high hygiene requirements in the medical sector.
