ABSTRACT:
An overcap sprayer assembly and method of its manufacture. The overcap sprayer assembly includes an actuator and an overcap. The actuator has a body and a sprayer arm. The body attaches preferably to the valve cup rim of the can. A skirt extends circumferentially around the perimeter of the body. At least one actuator access port provides access through the skirt to the interior of the body. The sprayer arm of the actuator has a nozzle adapted to direct spray outwardly through an actuator access port. The overcap attaches to the skirt of the actuator body in coaxially turning relation thereto. An overcap wall extends downwardly from the outer margins of the overcap dome, surrounding the actuator body. The overcap also has at least one overcap access port that may be moved between an open position, wherein an overcap access port is aligned with the actuator access port through which the nozzle is adapted to direct spray, and a closed position, wherein the overcap wall obstructs the actuator access port. Preferably a lock member extends from one of the actuator body and the overcap to project into and engage an opposed locking port of the other of the actuator body and overcap. Preferably the locking port is an access port. The lock member has an unlocked position, wherein it is not engaged in an opposed locking port and the overcap may freely turn on the actuator body, and a locked position assumed when the lock member becomes aligned with an opposed locking port, projects thereinto, and engages the opposed locking port, resisting further overcap turning.
