Abstract
Abstract A childproof dispensing valve actuator for an aerosol can. The valve actuator fits on the end of a vertical, tubular valve stem. The valve actuator body protrudes upwardly through a central opening in a can cover and has a horizontal nozzle which aligns with an opening in the side of the cover. The valve is actuated by pressing the actuator body downwardly. A locking slide is carried by a part of the cover adjacent the actuator body and is movable between an ''''open'''' position not engaging the actuator body and a ''''locked'''' position in which the slide engages in a slot in the actuator body for preventing it from being depressed to actuate the valve.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A childproof dispensing valve actuator for an aerosol can having a dispensing valve and a cover mounted on the top of said can and overlying said dispensing valve, said cover and said actuator having cooperating parts for guiding said actuator for providing for vertical movement only of said actuator relative to said cover, there being a generally central opening in said cover and said actuator protruding therethrough, said actuator having a main body adapted to fit over the stem of said dispensing valve and an interior passageway for conveying the content material from said valve to atmosphere, and a locking element and means engaged thereby in adjacent parts of said cover and said actuator body, said locking element being movable relative to both said cover and said actuator body between an ''''open'''' position not engaging said means and a ''''locked'''' position engaging said means and thereby preventing movement of said actuator relative to said cover or actuation of said valve thereby.
Claim 2
Dependent Claim
161 words
A childproof dispensing valve actuator for an aerosol can having a dispensing valve and a cover mounted on the top of said can and overlying said dispensing valve, said cover and said actuator having cooperating parts for guiding said actuator for providing for vertical movement only of said actuator relative to said cover, there being a generally central opening in said cover and said actuator protruding therethrough, said actuator having a main body adapted to fit over the stem of said dispensing valve and an interior passageway for conveying the content material from said valve to atmosphere, and a locking element and means engaged thereby in adjacent parts of said cover and said actuator body, said locking element being movable relative to both said cover and said actuator body between an ''''open'''' position not engaging said means and a ''''locked'''' position engaging said means and thereby preventing movement of said actuator relative to said cover or actuation of said valve thereby.
Claim 3
Dependent Claim
54 words
A device according to claim 1 in which the locking element is a slide mounted on the cover and the means engaged thereby is an undercut edge on the body of the actuator that is engageable by said slide in ''''locked'''' position for preventing depression of said actuator and actuation of the dispensing valve.
Claim 4
Dependent Claim
43 words
A device according to claim 2 in which the slide has a tongue on its end adjacent the body of the actuator and there is a recess in said actuator body into which said tongue is inserted for locking said actuator against depression.
