Abstract
Abstract A childproof safety closure for an aerosol dispenser comprising a button depressor having a locking rim and arming lug arranged in cooperative relation with a mounting cup adaptor having a split locking ring wherein the locking ring and locking rim operatively engage each other to hold the button depressor out of operative engagement with the button actuator to prevent actuation of the dispenser when in the ''''locked''''position and wherein rotation of the depressor and arming lug relative to the adaptor moves the locking ring out of operative engagement with the locking rim thereby ''''arming'''' the dispenser for actuation and on actuation the system automatically goes to the ''''locked'''' position.

Claim 1
Independent Claim
212 words
A childproof safety closure for an aerosol dispenser comprising a valve actuating means comprising a button depressor and button actuator, said button depressor having a button recess formed in the base thereof and a spray port formed in the side wall thereof, and a mounting cup adaptor operatively interconnected to said valve actuating means, said adaptor including attaching means to attach said safety closure to said dispenser, said valve actuating means including a first locking means comprising a locking rim formed about at least a portion of the periphery of said button depressor and said mounting cup adaptor including a second locking means comprising a locking ledge formed thereOn, said locking ledge comprising the upper portion of a substantially cylindrical vertical split locking ring formed in said adaptor, said locking ring including at least one slot formed in periphery thereof, said locking rim and said locking ledge engaging each other to hold said button depressor out of operative engagement with said button to prevent vertical movement of said actuating means relative to said adaptor, said safety closure further including arming means to disengage said second locking means from cooperative engagement with said first locking means to permit vertical movement of said actuating means relative to said adaptor thereby to actuate said dispenser.
Claim 2
Dependent Claim
212 words
A childproof safety closure for an aerosol dispenser comprising a valve actuating means comprising a button depressor and button actuator, said button depressor having a button recess formed in the base thereof and a spray port formed in the side wall thereof, and a mounting cup adaptor operatively interconnected to said valve actuating means, said adaptor including attaching means to attach said safety closure to said dispenser, said valve actuating means including a first locking means comprising a locking rim formed about at least a portion of the periphery of said button depressor and said mounting cup adaptor including a second locking means comprising a locking ledge formed thereOn, said locking ledge comprising the upper portion of a substantially cylindrical vertical split locking ring formed in said adaptor, said locking ring including at least one slot formed in periphery thereof, said locking rim and said locking ledge engaging each other to hold said button depressor out of operative engagement with said button to prevent vertical movement of said actuating means relative to said adaptor, said safety closure further including arming means to disengage said second locking means from cooperative engagement with said first locking means to permit vertical movement of said actuating means relative to said adaptor thereby to actuate said dispenser.
Claim 3
Dependent Claim
49 words
The safety closure of claim 1 wherein said arming means comprises at least one arming leg formed on said locking ring adjacent said slot said arming leg moved into operative engagement with a corresponding retaining stud formed on said adaptor by an arming lug formed on said button depressor.
Claim 4
Dependent Claim
45 words
The safety closure of claim 2 wherein said arming means comprises a pair of arming legs formed on opposite sides of said slot, said arming legs moved into operative engagement with a pair of corresponding retaining studs formed on said adaptor by said arming lug.
Claim 5
Dependent Claim
26 words
The safety closure of claim 3 further including disarming means to move said arming legs and said retaining studs out of operative engagement with one another.
