The tap, designed to be fitted into a hole in the wall of a small container to dispense the liquid contents as required, consists of a valve (2) or membrane sealing an outlet, operated by an actuator (4) behind a push-button (5). The valve is made in one piece with the actuator and with a spring (6) and guide (7) that close the valve when the pressure applied to the actuator to open the valve is released. The spring is in the form of a pair of elastic vanes connected to a fixing and centering member (8). |
