Abstract
Disclosed is a spray package having a container body, an actuator, and a shroud between the container body and the actuator. The actuator has a nozzle, and is adjustable between a locked position and an unlocked position by rotation of the nozzle about the actuator's longitudinal axis. The unlocked position allows vertical movement of the actuator for dispensing product from the package, and the locked position prevents vertical movement of the actuator to prohibit dispensing of product from the package. The locked position simultaneously provides cooperation between the nozzle and an anti-clog member, connected to and extending above the shroud. The anti-clog member has a nozzle seal on its inside surface which inhibits clogging of product within and about the nozzle when the seal is in contact with the nozzle.
