Abstract
A battery operated, hand-held fluid dispenser comprises a supply container having a body portion and a narrow neck extending upwardly therefrom. A pump and discharge unit is mounted on the upper end of the neck and comprises a pump diaphragm and pump chamber for pumping liquid from the container to a discharge nozzle. A battery powered pump drive unit is removably mounted on the container and comprises an electric motor having an output shaft coupled with the pump diaphragm to displace the latter through a pump stroke when the motor is energized. The pump drive unit is interconnected with the pump and discharge unit and with the body portion of the container and either alone or together with the neck provides a handle for holding the container during a dispensing operation. Removability of the pump drive unit provides for the latter to be usable with supply containers having different fluids to be dispensed.
