US Patent 9022257 Spout with a valve for dispensing liquor from a bottle

A pour spout has a bottle adapter for insertion into a mouth of a bottle. A housing has a chamber into which a housing inlet and a housing outlet open with the housing inlet connected to the bottle adapter for receiving beverage from the bottle. A valve carriage is movable within the chamber and has a carriage inlet in fluid communication with a carriage outlet. A resilient first tube provides a first beverage passageway between the housing inlet and the carriage inlet. A resilient second tube provides a second beverage passageway between carriage outlet and the housing outlet. The first or second tube has a valve seat that is engaged and disengaged by a plunger on the valve carriage as the valve carriage moves within the chamber. A valve actuator moves the valve carriage in response to signal from a control circuit that receives a wireless command signal.
