ABSTRACT:
A squeeze sprayer device is attached to a squeezable container of fluid. The device includes a capped cylinder containing an axially moveable discharge valve in the form of an air piston which unseats in response to air pressure to open the discharge upon squeezing the container for producing a fine mist spray as pressurized air admixes with the liquid at the discharge orifice. A one-way valve controlled air vent on the piston closes during the spray operation. Upon release of squeeze pressure, the piston returns, its one-way valve opens for venting, and the piston seal cuts off the spray.
