Patent ID: 7748572

Claim:
An aerosol fluid dispenser comprising: a rigid container defining a chamber for storing a fluid that is to be dispensed; a valve assembly including a valve cup and a movable valve stem, the valve cup connected to the container and defining an opening in fluid communication with the chamber, and the movable valve stem disposed in the opening for selectively closing the opening and retaining the fluid in the container at a pressure that is greater than atmospheric pressure; a shoulder connected to and surrounding an external surface of the container and including a central opening and at least one slot extending from the central opening; a spray through actuator received in the central opening of the shoulder and including an outlet for dispensing the fluid, an upper platform, a stem socket depending downwardly from the upper platform and an outer wall extending downwardly from the upper platform and at least substantially surrounding the stem socket, the stem socket defining a passage that receives the valve stem and is in communication with the outlet, the stem socket including at least one spline that is received in the at least one slot to inhibit rotational movement of the actuator with respect to the shoulder; a spring located above a seat for the valve stem, beneath and aligned in the same axial direction as the actuator, which provides a biasing force against the vertical up and down motion of the actuator; and a locking ring rotatably connected to the shoulder and cooperating with the actuator to limit axial movement of the actuator.
