6. The actuator apparatus of claim 5 , wherein each female locking structure of the first and second female locking structures of the lower portion of the base comprise a first and second rib, wherein each rib of the first and second rib extend outwardly from the lower portion of the base; and

wherein the male locking structure of the outer wall portion of the cover comprises:

a deflectable portion for deflectably engaging the first rib of the first female locking structure of the lower portion of the base when the cover is moving into the locked position and for deflectably engaging the first rib of the second female locking structure of the lower portion of the base when the cover is moving into the unlocked position; and

a rigid portion for engaging the second rib of the first female locking structure of the base when the cover is moved into the locked position to stop the cover from moving past the locked position and for engaging the second rib of the second female locking structure of the base when the cover is moved into the unlocked position to stop the cover from moving past the unlocked position.

7. The actuator apparatus of claim 1 , wherein the base further comprises a spray opening shield portion for blocking the spray opening of the cover when the cover is in the locked position, wherein the spray opening shield extends upwardly from the lower portion of the base.

8. The actuator apparatus of claim 1 , wherein the cover further comprises:

an inner wall portion defining the push button opening lying along the axis of the actuator apparatus;

an outer wall portion located further away from the axis of the actuator apparatus than the inner wall portion; and

an annular flange located on an interior surface of the outer wall portion of the cover extending inwardly towards the axis of the actuator apparatus, wherein the lower portion of the base further comprises at least one deflectable cover retention rib for engaging the annular flange of the cover to couple the cover to the lower portion of the base.

9. The actuator apparatus of claim 8 , wherein the at least one deflectable cover retention rib of the lower portion of the base defines an annular gap extending at least partially around the lower portion of the base for receiving the annular flange of the cover to allow the cover and the base to move relative to each other.

10. The actuator apparatus of claim 1 , wherein the base is fixed relative to the spray container, and further wherein the cover is rotatable relative to the base between the locked and unlocked positions.

11. The actuator apparatus of claim 1 , wherein the cover comprises only one restraint structure.

12. The actuator apparatus of claim 1 , wherein the lower portion of the base of the actuator apparatus is coupled to a spray can, and wherein the spray can contains a liquid material.

13. The actuator apparatus of claim 12 , wherein the liquid material contained by the spray can comprises paint.

14. An actuator apparatus for a spray container, wherein the actuator apparatus comprises:

a base comprising:

a lower portion couplable to the spray container; and

a push button depressibly attached to the lower portion wherein the push button comprises:

a body portion extending along an axis of the actuator apparatus between a first end region connectable to the lower portion of the base and a second end region to be contacted for depression of the push button by a user;

an aperture portion extending radially from a region of the body portion, wherein the aperture portion defines an exit aperture; and

a receiver stem portion for receiving a valve assembly, wherein the receiver stem portion defines an entrance aperture, wherein a fluid passageway extends between the entrance aperture and the exit aperture, wherein the push button is movable relative to the lower portion of the base between at least a normal position and a depressed position, wherein the push button actuates the valve assembly when in the depressed position to provide a spray through the exit aperture, wherein the lower portion of the base defines a push button aperture, wherein at least a portion of the body portion of the push button is located within the push button aperture of the lower portion of the base when the push button is in the depressed position; and

a cover coupled to the base, wherein the cover defines a push button opening that permits access to the second end region of the body portion of the push button to allow depression of the push button by the user, wherein the cover and the base are movable relative to each other between at least a locked position such that the push button is restricted from moving into the depressed position and an unlocked position such that the push button is allowed to move into the depressed position, wherein the cover further defines a spray opening alignable with the exit aperture of the aperture portion when the cover is in the unlocked position, wherein the cover comprises a restraint structure, wherein the restraint structure is located below the aperture portion of the push button of the base to restrict the push button from moving into the depressed position when the cover is in the locked position.

15. An actuator apparatus for a spray container, wherein the actuator apparatus comprises:

a base comprising:

a lower portion couplable to the spray container; and

a push button depressibly attached to the lower portion, wherein the push button comprises:

a body portion extending between a first end region connectable to the lower portion of the base and a second end region to be contacted for depression of the push button by a user; and
