  • Actuator and cap for a fluid dispenser
    Patent number: 5255823
    Abstract: An actuator having an actuator body and a cap that can be raised or retracted is disclosed. The cap has an aperture sized to fit around the body. In the raised position, the actuator fits into the aperture and the body upper end is shaped to conform with the upper surface of the cap. This encloses the nozzle and provides a smooth upper surface when the cap is raised. When the cap is retracted, the body extends upwardly through the aperture so that it may be pushed on to dispense a liquid from the container on which the actuator is mounted.
