Claim 2

A valve safety lock device for an aerosol dispens-er comprising a valve actuating means including a button actuator and a valve stem, said valve actuating means further including a first locking means comprising at least one locking foot formed on said valve stem, said aerosol dispenser including a second locking means comprising a locking ledge formed on the valve body of said dispenser, said first and second locking means cooperative-ly engaging each other to prevent vertical movement of said valve actuation means relative to said dispenser, said safety lock de-vice further including arming means comprising an arming tip formed on said locking foot and an arming nub formed on said locking ledge to disengage said second locking means from cooperative engagement with said first locking means to permit vertical move-ment of said valve actuating means relative to said dispenser to actuate said dispenser.

Claim 3

The valve safety lock deVice of claim 1 wherein said arming tip projects outwardly from the lower end of said locking foot and said locking nub projects upwardly from the said locking ledge such that when said valve actuating means is rotated relative to said aerosol dispenser said arming tip engages the side of said nub to disengage said locking foot from said locking ledge to permit vertical movement of said valve actuating means relative to said dispenser to actuate said dispenser.

Claim 4

The valve safety lock device of claim 1 wherein said first locking means comprises a plurality of locking feet formed in a substantially inverted V-shaped configuration and said second locking means comprises a locking ledge formed on a cavity formed in said valve body, said locking ledge comprising an interrupted annular rim forming at least two slots by adjacent locking ledges each end of said locking ledges including said arming nub such that when said valve actuating means is rotated counter clockwise and clockwise relative to said dispenser said feet are retained within said vertical slots by the cooperative engagement of said arming tips and arming nubs to permit vertical actuation of said valve actuating means.

Claim 5

A valve safety lock device for an aerosol dispenser comprising a valve actuating means including a button actuator and a valve stem, said valve actuating means further including a first locking means comprising a pair of vertically disposed locking feet formed on opposite sides of said valve actuator, said aerosol dispenser including a second locking means comprsing an interrupted annular rim forming at least two slots by adjacent locking ledges, said first and second locking means cooperatively engaging each other to prevent vertical movement of said valve actuating means relative to said dispenser, said safety lock device further including arming means comprising an arming tip formed on each of said locking feet and an arming nub formed on each of said locking ledges, said arming tip projecting outwardly from the lower end of each of said locking feet and said locking nub projecting upwardly from each of said locking ledges such that when said valve actuating means is rotated counter-clockwise and clockwise relative to said dispenser said feet are retained within said vertical clots by the cooperative engagement of said arming tips and arming nubs to permit vertical actuation of said valve actuating means.

Claim 6

A valve safety lock device for an aerosol dispenser comprising a valve actuating means including a button actuator and a valve stem, said valve actuating means further including a first locking means comprising a pair of vertically disposed locking feet formed on opposite sides of said valve actuator, said aerosol dispenser including a second locking means comprsing an interrupted annular rim forming at least two slots by adjacent locking ledges, said first and second locking means cooperatively engaging each other to prevent vertical movement of said valve actuating means relative to said dispenser, said safety lock device further including arming means comprising an arming tip formed on each of said locking feet and an arming nub formed on each of said locking ledges, said arming tip projecting outwardly from the lower end of each of said locking feet and said locking nub projecting upwardly from each of said locking ledges such that when said valve actuating means is rotated counter-clockwise and clockwise relative to said dispenser said feet are retained within said vertical clots by the cooperative engagement of said arming tips and arming nubs to permit vertical actuation of said valve actuating means.

Claim 7

The valve safety lock device of claim 1 wherein said second locking means comprises a plurality of annular interrupted locking ledges arranged in vertical configuration relative to one another to permit use with various size valves.

Claim 8

The valve safety locking device of claim 4 further including an outwardly projecting alignment lug formed on the side wall of said dispenser and said button actuator includes a vertically disposed alignment slot.

Claim 9

The valve safety locking device of claim 6 further including a tamper proof detachable bar formed on said overcap disposed within said vertical alignment slot to prevent rotation of said valve actuating means relative to said disenser.
