A child-resistant fluid delivery device, comprising a container for storing fluid to be dispensed by the fluid delivery device and a wand assembly connected to the container. The wand assembly having a nozzle at a distal end through which fluid may be dispensed and a child-resistant connector at a proximal end. A ratchet mechanism is formed on the exterior of the child-resistant connector to permit attachment of the connector to the container and thereafter prevent removal of the connector from the container. The nozzle is sealed by a removable, child-resistant cover that includes at least one member that engages the nozzle to resist removal therefrom.

1. A child-resistant fluid delivery device, comprising:a container for storing fluid to be dispensed by the fluid delivery device;a wand having a proximal end, a distal end and a fluid passageway therethrough;a nozzle at the distal end of the wand; anda removable, child-resistant cover for sealing the nozzle, the child-resistant cover including at least one rigid tab inwardly projection into an interior region of the child-resistant cover to resist removal of the cover from the nozzle;first ratchet mechanism having a plurality of ratchet teeth formed along the circumference of the wand, the ratchet teeth engaging the at least one inwardly projecting tab, the ratchet teeth being configured to permit rotation of the cover relative to the nozzle in a first direction that permits attachment of the cover onto the nozzle and to prevent rotation in an opposing direction to resist removal of the cover from the nozzle. 2. The child-resistant fluid delivery device according to claim 1, wherein internal threads formed in the child-resistant cover engage external threads formed on the nozzle to permit the cover to be threaded onto the nozzle. 3. The child-resistant fluid delivery device according to claim 1, wherein the at least one inwardly projecting tab may be disengaged from the ratchet teeth by deforming the child-resistant cover to permit rotation of the cover relative to the nozzle in the opposing direction to remove the cover from the nozzle. 4. The child-resistant fluid delivery device according to claim 1, further comprising a child-resistant connector at the proximal end of the wand for connecting the wand to the container. 5. The child-resistant fluid delivery device according to claim 4, further comprising a second ratchet mechanism formed on the exterior of the child-resistant connector to permit attachment of the connector to the container and thereafter resist removal of the connector from the container. 6. The child-resistant fluid delivery device according to claim 5, wherein the second ratchet mechanism comprises a plurality of ratchet teeth formed about the perimeter of the child-resistant connector for engaging at least one rigid tab formed on the container, the teeth being configured to permit movement of the child-resistant connector relative to the container in a first direction and to resist such movement in an opposing direction. 7. The child-resistant fluid delivery device according to claim 4, wherein the container includes an externally threaded spout for engaging internal threads formed within the child-resistant connector. 8. The child-resistant fluid delivery device according to claim 1, wherein the fluid passageway in the wand provides a fluid communication path for fluid to pass from the container to the nozzle. 9. The child-resistant fluid delivery device according to claim 1, further comprising a valve for controlling the flow of fluid through the wand. 10. The child-resistant fluid delivery device according to claim 9, wherein the valve is movable from a first position that prevents the flow of fluid through the wand to a second position that permits the flow of fluid through the wand. 11. The child-resistant fluid delivery device according to claim 1, wherein the nozzle is formed integrally with the distal end of the wand. 12. The child-resistant fluid delivery device according to claim 1, wherein the nozzle is threaded onto the distal end of the wand. 13. The child-resistant fluid delivery device according to claim 1, wherein the child-resistant cover is tethered to the wand. 14. The child-resistant fluid delivery device according to claim 1, further comprising a pump for pressurizing the fluid within the container. 15. The child-resistant fluid delivery device according to claim 1, wherein the fluid within the container is pressurized by squeezing the container. 16. A wand assembly for a child-resistant fluid delivery device that includes a container for storing fluid to be dispensed by the fluid d elivery device, the wand assembly comprising:a tube having a proximal end, a distal end and a fluid passageway therethrough;a nozzle at the distal end of the tube; anda removable, child-resistant cover for sealing the nozzle, the child-resistant cover including at least one rigid tab inwardly projecting into an interior region of the child-resistant cover to resist removal of the cover from the nozzle;a ratchet mechanism having a plurality of ratchet teeth formed along the circumference of the tube, the ratchet teeth engaging the at least one inwardly projecting tab, the ratchet teeth being configured to permit rotation of the cover relative to the nozzle in a first direction that permits attachment of the cover onto the nozzle and to prevent rotation in an opposing direction to resist removal of the cover from the nozzle. 17. The wand assembly according to claim 16, wherein internal threads formed in the child-resistant cover engage external threads formed on the nozzle to permit the cover to be threaded onto the nozzle. 18. The wand assembly according to claim 16, wherein the at least one inwardly projecting tab may be disengaged from the ratchet teeth by deforming the child-resistant cover to permit rotation of the cover relative to the nozzle in the opposing direction to remove the cover from the nozzle. 19. The wand assembly according to claim 16, further comprising a connector at the proximal end of the tube adapted to connect the wand assembly to the container. 20. The wand assembly according to claim 19, further comprising a second ratchet mechanism formed on the exterior of the connector for permitting attachment of the connector to the container and thereafter resisting removal of the connector from the container. 21. The wand assembly according to claim 20, Wherein the second ratchet mechanism comprises a plurality of ratchet teeth formed about the perimeter of the connector for engaging at least one rigid tab formed on the container, the teeth being configured to permit movement of the connector relative to the container in a first direction and to resist such movement in an opposing direction. 22. The wand assembly according to claim 16, further comprising means for connecting the wand assembly to the container. 23. The wand assembly according to claim 19, wherein the connector includes internal threads for engaging external threads formed on the container. 24. The wand assembly according to claim 16, wherein the fluid passageway in the tube provides a fluid communication path for fluid to pass from the container to the nozzle. 25. The wand assembly according to claim 16, further comprising a valve for controlling the flow of fluid through the fluid passageway. 26. The wand assembly according to claim 25, wherein the valve is movable from a first position for preventing the flow of fluid through the fluid passageway to a second position for permitting the flow of fluid through the fluid passageway. 27.
