The invention related to a "flow control element" with suction spout for carbonated beverage cans. The fluid remains under pressure while access is possible when suction is applied to the spout. The spout is attached to a housing enclosure that holds a spring, a centrally perforated membrane, a valve stem and a valve. This housing enclosure extends into the inside of th e container, which extended part functions as a guide for the valve stem and that incorporates the valve seat. The valve stem is attached to the perforat ed membrane on one side and to the valve on the other side. When suction is applied the membrane moves the valve and opens a flow path, thereby allowing fluid to flow through the valve stem and the perforated membrane to the mout h. When the suction stops, a spring closes the valve against the gas pressure i n the can or container. |
