The piston comprises a stem on which is located an inwardly located flexing element serving as a one-way valve to permit fluid flow outwardly past the flexing element and a sealing element located outwardly of the flexing element. A channel is provided from an inlet on the piston between the flexing element and the sealing element through which the dispensed liquid flows.
