Bottle top dispensers are a safe, accurate and efficient way to measure and dispense liquids straight from the bottle. This involves a piston on a plunger which is pushed down against a spring: as the spring pushes the piston back into its original position, it draws the medium up from a reservoir underneath. When pushed down again, plunger infuses the medium out the dispenser tip.
