An aerosol dispensing device includes a rotating actuator, an upstanding wall partially surrounding the actuator, and a sliding nozzle closure. The actuator may include a spray nozzle and a downwardly extending projection, in fluid communication with the spray nozzle, to sealingly engage an upwardly projecting stem of an aerosol valve. The upstanding wall may include an upper opening, a lower opening below the upper opening, and a spray opening. The sliding nozzle closure may include an upper projection, fitting into the upper opening and the spray nozzle, to seal the spray nozzle when the actuator is in a non-dispensing position, and, a lower member, fitting into the lower opening, to facilitate the sliding movement of the nozzle closure.

1. An aerosol dispensing device, comprising:an actuator, including: a spray nozzle, and a downwardly extending projection, in fluid communication with the spray nozzle, to sealingly engage an upwardly projecting stem of an aerosol valve; an upstanding wall, at least partially surrounding the actuator, including: an upper opening adjacent to the spray nozzle when the actuator is in a non-dispensing position, a lower opening below the upper opening, and a spray opening adjacent to the spray nozzle when the actuator is in a dispensing position; and a nozzle closure, including: an upper projection, fitting into the upper opening and the spray nozzle, to seal the spray nozzle when the actuator is in the non-dispensing position, and a lower member, fitting into the lower opening, in sliding contact with the upstanding wall and the upwardly projecting stem. 2. The device of claim 1, wherein:the actuator includes a projecting edge; and the upstanding wall includes a posterior opening to permit downward movement of the actuator when the actuator is oriented in a dispensing position. 3. The device of claim 2, wherein the posterior opening includes:a vertical wall; a first limit stop to engage the projecting edge of the actuator and prevent downward movement of the actuator when the actuator is oriented in a non-dispensing position; and a second limit stop to engage the projecting edge of the actuator and limit the downward excursion of the actuator when the actuator is oriented in a dispensing position. 4. The device of claim 3, wherein the actuator includes an outwardly biased hinged tab having a projecting lip abutting the vertical wall to prevent rotation of said actuator from the non-dispensing position to the dispensing position, unless the tab is pushed in to clear the vertical wall, while at the same time rotating the actuator from the non-dispensing position to the dispensing position.5. The device of claim 4, wherein the tab includes a lower part which is part of a wall of the actuator, and an upper part containing the projecting lip forming the portion abutting the vertical wall.6. The device of claim 5, wherein the tab is integrally molded with the actuator and separated from the actuator by an upper slit and two side slits so as to form a bottom hinge about which said tab may rotate.7. The device of claim 1, wherein the nozzle closure includes a projecting flange to facilitate extraction of the nozzle closure from the spray nozzle.8. The device of claim 1, wherein the lower member includes a cutout to receive the upwardly projecting stem of the aerosol valve.9. The device of claim 8, wherein the lower member includes an extraction projection to abut an inner surface of the upstanding wall and limit an extraction distance of the nozzle closure.10. The device of claim 9, wherein the lower member includes a cross-piece to abut the upwardly projecting stem of the aerosol valve and limit an insertion distance of the nozzle closure.11. The device of claim 1, further comprising a breakaway tab, disposed within the spray opening, to cover the spray nozzle when the actuator is in the dispensing position.12. The device of claim 1, wherein the upstanding wall includes a mounting cap to engage a mounting cup of an aerosol container, the mounting cap having an upstanding breakaway tab, adjacent to the spray opening, to cover the spray nozzle when the actuator is in the dispensing position.13. An aerosol dispenser, comprising:an aerosol container; a mounting cup, attached to the aerosol container, including: a beaded rim, and an upwardly projecting stem attached to an aerosol valve; an actuator, including: a spray nozzle; and a downwardly extending projection, in fluid communication with the spray nozzle, to sealingly engage the upwardly projecting stem; a mounting cap, including: a skirt to engage the beaded rim, and an upstanding wall, at least partially surrounding the actuator, including: an upper opening, and a lower opening below the upper opening; and a nozzle closure, including: an upper projection, fitting into the upper opening and the spray nozzle, to seal the spray nozzle when the actuator is in the non-dispensing position, and a lower member, fitting into the lower opening, in sliding contact with the upstanding wall and the upwardly projecting stem. 14. The dispenser of claim 13, wherein:the actuator includes a projecting edge; and the upstanding wall includes a posterior opening to permit downward movement of the actuator when the actuator is oriented in a dispensing position. 15. The dispenser of claim 14, wherein the posterior opening includes:a vertical wall; a first limit stop to engage the projecting edge of the actuator and prevent downward movement of the actuator when the actuator is oriented in a non-dispensing position; and a second limit stop to engage the projecting edge of the actuator and limit the downward excursion of the actuator when the actuator is oriented in a dispensing position. 16. The dispenser of claim 15, wherein the actuator includes an outwardly biased hinged tab having a projecting lip abutting the vertical wall to prevent rotation of said actuator from the non-dispensing position to the dispensing position, unless the tab is pushed in to clear the vertical wall while at the same time rotating the actuator from the non-dispensing position to the dispensing position.17. The dispenser of claim 16, wherein the tab includes a lower part which is part of a wall of the actuator, and an upper part containing the projecting lip forming the portion abutting the vertical wall.18. The dispenser of claim 17, wherein the tab is integrally molded with the actuator and separated from the actuator by an upper slit and two side slits so as to form a bottom hinge about which said tab may rotate.19. The dispenser of claim 13, wherein the nozzle closure includes a projecting flange to facilitate extraction of the nozzle closure from the spray nozzle.20. The dispenser of claim 13, wherein the lower member includes a cutout to receive the upwardly projecting stem.21. The dispenser of claim 20, wherein the lower member includes an extraction projection to abut an inner surface of the upstanding wall and limit an extraction distance of the nozzle closure.22. The dispenser of claim 21, wherein the lower member includes a cross-piece to abut the upwardly projecting stem and limit an insertion distance of the nozzle closure.23. The dispenser of claim 13, further comprising a breakaway tab, disposed within the spray opening, to cover the spray nozzle when the actuator is in the dispensing position.24. The dispenser of claim 13, further comprising a breakaway tab, attached to the mounting cap and adjacent to the spray opening, to cover the spray nozzle when the actuator is in the dispensing position.
