1. A liquid dispensing device comprising:

  • a chamber in which a liquid to be dispensed is retained in use, the chamber having a first and a second opening;

    a one way valve retained in the first opening to allow liquid flow only out of the chamber;

    a closure slidably retained in the chamber to close the second opening, the closure including an actuator having a flexible element which, upon actuation, is caused to extend into the chamber reducing its volume and thereby causing liquid to be expelled from the chamber through the valve, wherein, when actuation is stopped, the closure is caused to slide in the chamber so as to reduce the volume of the chamber by the amount of the dispensed liquid.
