Abstract: Liquid dispenser having a liquid store and a discharge device fitted thereto and having a discharge opening. The discharge device has a pump device with a pump chamber variable in terms of volume and connected at an input side in a communicating manner to the liquid store and at an output side in a communicating manner to the discharge opening. The pump device conveys liquid from the liquid store to the discharge opening. The discharge device has a ventilation channel, by which an incoming air flow is enabled for pressure compensation between the liquid store and a surrounding atmosphere. The ventilation channel has a ventilation valve openable by manual actuation of the pump device and closed when the pump device is not actuated. Further, the ventilation channel has a capillary channel portion through which the incoming air flow reaches the liquid store.
