Bottle mounted adjustable liquor dispensing device

摘要

The device consists of a cylindrical body divided into an upper filling chamber and a lower overflow chamber by a moveable wall which increases or decreases the size of the filling chamber and determines the amount of liquor to be dispensed. Once the upper chamber is visually determined to be filled a rearward pumping action of the outer body opens the releasing cap and at the same time shuts off the flow of liquor into the filling chamber. The device is attached by insertion into the neck opening of a bottle.
