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 the spray position will disengage the locking mechanism and stop the dispensing of the contents of the container 14.

An overcap assembly, comprising an actuator unit and a nozzle device, said actuator unit having means defining an outlet passage and having an acutator adapted for opening a valve of a container having contents under pressure to release the contents into said outlet passage, said nozzle device having a first outlet adapted to produce a spray of a material passing therethrough and a second outlet adapted to produce a for of a material passing therethrough, the axis of said second outlet being substantially transverse with respect to the axis of said first outlet, said nozzle device being connected to said actuator unit to selectively permit one or the other of said outlets to be in communication with said outlet passage of said actuator unit, wherein said nozzle device is movable, while connected to said actuator unit, between first and second positions relative to said actuator unit, said first and said second outlets respectively being in communication with said outlet passage when said nozzle device is in said first and said second positions, respectively, wherein said nozzle device and said actuator unit each have a respective cooperating locking member means for locking said actuator in a position to maintain open the valve of the container with which said assembly is being used, said locking member means being shaped and positioned so as to engage each other and lock upon operation of said actuator when said nozzle device is in said second relative position, and said locking member means being shaped and positioned so as to remain disengaged from each other when said nozzle device is in said first relative position, whereby actuation of the valve by said actuator will selectively produce a spray or a fog of the contents of the container.
