A dispenser having a manually-operated dispensing valve assembly has a container for accommodating a spray product. The bottom of the container has a recess adapted to cooperate with a tube used to deliver air under pressure from an air pump into the container. The container includes a check valve which allows air to flow into the chamber of the container and prevent the flow of air out of the chamber of the container. When the container is placed on the air pump, it actuates a switch which energizes an electric motor which drives a pump for supplying air under pressure which is directed to the tube and into the chamber of the container past the check valve.

An apparatus for dispensing a spray product to a selected location comprising: a container having a chamber for storing a pressurized spray product, valve assembly mounted on the container operable to be moved to a first position to spray the product to a selected location and a second position to prevent the dispensing of the product, actuator means connected to the valve assembly, used by a person to move the valve assembly to the first position, and nozzle means mounted on the actuator means to direct spray product to a selected location, said actuator means having a passage for carrying spray product from the valve assembly to the nozzle means when the valve assembly has been moved to the first position, the nozzle means includes a head having a wall and at least one orifice in said wall open to the passage in the actuator means whereby when the valve assembly has been moved to the first position, the spray product is discharged through said at least one orifice to a selected location, the valve assembly has a sleeve and a tubular member slideably mounted in said sleeve, said actuator being mounted on the tubular member, said tubular member having a passage for carrying the spray product from the container chamber to the actuator means, seal means for controlling the flow of spray product into the passage, said sleeve and tubular member having portions separated from each other producing an annular space isolated from the spray product in the valve assembly, biasing means located in the annular space for biasing the valve assembly to the second position, said biasing means being isolated from the spray product which flows through the passage of the tubular means.
