Abstract

Abstract An aerosol valve safety-lock device for an aerosol dispenser including a valve actuating means comprising a button actuator and valve stem having a plurality of locking legs formed thereon to operatively engage corresponding locking ledges formed within the dispenser to prevent vertical movement of the valve actuating means relative to the dispenser when in the ''''locked'''' position. The device further includes arming means to move the locking legs out of operative engagement with the locking ledges to permit vertical movement of the valve actuating means relative to the dispenser to actuate the dispenser.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 143 words
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 2
Dependent Claim 143 words
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
Dependent Claim 82 words
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
Dependent Claim 116 words
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
Dependent Claim 194 words
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
Dependent Claim 194 words
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
Dependent Claim 36 words
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
Dependent Claim 33 words
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
Dependent Claim 37 words
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.
