Abstract
An overcap assembly for a container having a pressure valve or the like, for dispensing a product selectively as a spray or a fog. The assembly has an overcap and a nozzle device which can be attached to the overcap outlet and is rotatable or otherwise movable between two positions relative to the overcap. In one position, a first outlet of the nozzle device communicates with the pressure valve of the container, while a second outlet of the nozzle device does so in the second relative position. One outlet is suitable for producing a spray, while the other is for producing a fog. Preferably, locking members are provided to lock the overcap actuator in a position to hold the container valve open when the nozzle device is in one (but not the other) of the two positions, to ensure complete use of the product in the container. It should also be noted that because of the construction of flange 96 and lip 46, the mere moving of the nozzle device 16 to the fog position does not actuate the container until button 20 is depressed. This prevents accidental actuation which is a problem with other total release systems. Also in the event of accidental actuation, rotation of nozzle device 16 to …
