Soap dispenser which is actuated by the pressing of a push-button which is designed for said purpose, and which in turn has a double retainer which prevents dripping, the liquid being retained by a ball and a seal which exerts pressure on the exit for the soap from the reservoir, preventing said dripping and the undesired exit of soap. The supply is obtained through the effect of the pressure which the push-button, when pressed in, produces in the inner chamber, and it cannot return to the reservoir via the non-return valve which it possesses, which forces the liquid to overcome the retention effect produced by the sphere, pressed by a spring, located in the exit conduit. Applicable to liquid-soap-dispenser apparatuses. <IMAGE>
