Abstract: A multi-chambered bottle includes first and second chambers, a metering stage, a pour spout and a cap. The metering stage includes first and second metering stage sections connectable to respective mouths of the first and second chambers. Each metering stage section comprises a nozzle having a liquid inlet orifice and a liquid outlet orifice, and a vent tube having an air inlet orifice and an air outlet orifice at opposite ends of the vent tube, the air inlet orifice to be disposed outside of the respective chamber and the air outlet orifice to be disposed inside of the respective chamber, the vent tube disposed relative to the nozzle such that a line crossing a center of the air inlet orifice and a center of the liquid outlet orifice forms an acute angle with a normal axis of the bottle.
