Nozzle closures which are mounted for pivoting movement from a closed to an open position are used with a spray dispensing device. In the open position, the nozzle closure moves away from the spray nozzle on an actuator and a spray opening in a surrounding wall, allowing fluid to dispensed through the nozzle, as the actuator is depressed. In the closed position, the nozzle closure pivots into a position where a projection enters at least partially into the spray nozzle. The projection acts to seal the spray nozzle against air, thereby preventing drying of any fluid in the nozzle and reducing the chance that the spray nozzle will become clogged. The projection also serves to provide resistance against depression of the actuator, thereby providing a locking function for the actuator to prevent accidental discharge from the spray nozzle. The sealing finger completely covers a spray opening in a wall surrounding the actuator.

[ What is claimed is:] [1.]1. A spray dispensing device, comprising:an actuator, the actuator including a spray nozzle and an opening adjacent the spray nozzle, the actuator dispensing spray through the spray nozzle when the actuator is depressed, the spray nozzle moving with the actuator when it is depressed;a wall at least partially surrounding the actuator, the wall including a spray opening, the spray nozzle being aligned with the spray opening during dispensing whereby spray exiting the spray nozzle passes through the spray opening; anda nozzle closure, the nozzle closure including a projection, the projection fitting into the opening adjacent the spray nozzle thereby sealing the spray nozzle, the nozzle closure further including a hinge, the hinge allowing pivotal movement of the nozzle closure from a closed position, at which the projection fits into the opening in the wall adjacent the spray nozzle and the nozzle closure closes the spray opening, to an open position, where the spray opening is open to permit the spray to pass through the spray opening when the actuator is depressed. [11.]11. A method of dispensing spray, comprising:providing an actuator including a spray nozzle and an opening adjacent the spray nozzle,surrounding said actuator with a wall including a spray opening with which the spray nozzle is aligned, and a nozzle closure including a projection;pivoting the nozzle closure away from the spray nozzle and the spray opening to an open position;depressing the actuator to thereby dispense spray through the spray nozzle and the spray opening, the spray nozzle moving with the actuator during the depressing;pivoting the nozzle closure toward the spray nozzle and spray opening to a closed position so that the projection fits into the opening adjacent the spray nozzle thereby sealing the spray nozzle and the nozzle closure closes the spray opening in the wall.12. The method of claim 11, wherein said step of pivoting comprises pivoting out an axis parallel to a direction of actuation of the nozzle.13. The method of claim 11, wherein said step of pivoting comprises pivoting about an axis perpendicular to a direction of actuation of the nozzle.14. The method of claim 11, further comprising:fitting at least a portion of the hinge into a recess in the actuator, thereby preventing rotation of the actuator.15. The method of claim 11, further comprising:engaging a flattened surface on the hinge with a flattened section in a bearing on the wall to lock the nozzle closure in the open position.16. The method of claim 11, further comprising:detachably connecting the nozzle closure to the wall.17. A method of dispensing spray, comprising:providing an actuator including a spray nozzle and an opening adjacent the spray nozzle, a wall including a spray opening with which the spray nozzle is aligned, and a nozzle closure including a projection;pivoting the nozzle closure away from the spray nozzle and the spray opening to an open positiondepressing the actuator to thereby dispense spray through the spray nozzle and the spray opening;pivoting the nozzle closure toward the spray nozzle and spray opening to a closed position so that the projection fits into the opening adjacent the spray nozzle thereby sealing the spray nozzle and the nozzle closure closes the spray opening; andengaging a locking flange on the nozzle with the actuator in the closed position of the nozzle closure to thereby lock the actuator against depression.18. A method of dispensing spray, comprising:providing an actuator including a spray nozzle and an opening adjacent the spray nozzle, a wall including a spray opening with which the spray nozzle is aligned, and a nozzle closure including a projection:pivoting the nozzle closure away from the spray nozzle and the spray opening to an open position:depressing the actuator to thereby dispense spray through the spray nozzle and the spray opening;pivoting the nozzle closure toward the spray nozzle and spray opening to a closed position so that the projection fits into the opening adjacent the spray nozzle thereby sealing the spray nozzle and the nozzle closure closes the spray opening;detachably connecting the nozzle closure to the wall; andconnecting the nozzle closure to the wall using an attachment ring fitting inside the wall.
