Abstract
A spray dispensing head for a squeeze dispenser is disclosed. The dispensing head includes passageways for directing streams of air and liquid to a mixing chamber wherein the liquid is broken up into droplets and emitted as a fine spray through an orifice. The device includes a valve which is operated by a push-pull motion. When the valve is closed, the liquid is sealed off from the atmosphere, thus preventing drying or contamination of the liquid product.
