SELF CLOSING FLOW CONTROL DEVICE WITH ADJUSTABLE ACTUATOR ELEMENT FOR CONTAINER CLOSURES

WIPO Patent Application WO/2013/014559

A1

The invention relates to a spill proof self-closing flow control device (SCFCD) with adjustable actuator element for flexible or rigid containers with fluids. The SCFCD comprises a spout (2), a flexible valve-retaining element and a container closure element (12). The valve-retaining element is a one-part component consisting of an actuator element (9), a cylindrical valve holder (11) and a valve (10) for alternately opening and closing the flow-through orifice. In the various embodiments two or three pressure chambers are formed with pressures P1, P2 and P3 controlling the flow control device, separated by the valve- retaining element. In a first, second and fourth embodiments the actuator element is configured to move the valve in the downstream direction by an under pressure in the first chamber thereby bringing the valve in the open position, while in a third embodiment, the actuator element opens the valve in the upstream direction. Provisions are foreseen to increase the fluid outflow from container by externally adjusting the opening/closing force of the actuator element.
