The measuring dispenser includes a fixed assembly having liquid and air passages an external guide, a slidable assembly having pouring, measuring and connecting chambers and an internal guide slidably sealed on the external guide to slidably mount theslidable assembly on the fixed assembly. A valve assembly is actuated by the slidable assembly which is spring biased to a normal position closing the outlet valve for sealed storage and measuring. A manual operator adjacent the guide and top of the bottle provides for convenient signle hand gripping of the bottle and manual operation to move the slidable assembly to its dispensing position. The valve assembly functions to push liquid to initiate dispensing pouring flow from the measuring chamber. An external air vent is connected only to the pouring chamber, and an improved connecting chamber with air passage and liquid passage to maintain separated liquid and air flows to avoid air lock between the dispenser and bottle are also provided.
