Abstract
Abstract A safety-type, child-resistant actuator comprising a jumbo size, two-piece overcap which is freely turnable on the top of the aerosol container. The overcap has the appearance of a single plastic molding, even though it actually consists of an inverted dome portion which is screwed to an annular collar or base portion, the latter being held captive although it is freely turnable. By grasping and holding the base portion while twisting the dome, the latter can be readily removed, revealing a lockingtype actuator button provided with a hook which can be latched under an annular shoulder of the top closure for the container. The latching of the actuator is normally prevented, due to an obstruction provided on the turnable base. However, by aligning an inconspicuous notch of the base with the latching hook of the actuator button, the latter can be deflected or tilted to cause its hook portion to latch under the shoulder of the container closure. The combination of the deceptive ''''one-piece'''' appearance of the overcap with the inconspicuous nature of the notch in the turnable base has the net result of presenting considerable difficulty to a child of tender years, if he should endeavor to place the dispenser in use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
151 words
An aerosol dispenser comprising, in combination: a. a pressurized container having a tilt-type discharge valve provided with a protruding tiltable valve stem, and having a valve mounting cup carrying said valve and stem, b. said cup having an annular exterior shoulder provided with an undercut, c. an annular collar surrounding said cup and turnable thereabout, d. an orificed actuator button carried by the valve stem, e. said button having a laterally extending hook which is adapted to latch under the shoulder of the cap when the button is laterally displaced to tilt the valve stem for discharge, f. said collar having inner peripheral portions adapted to engage and obstruct said hook so as to prevent discharging movement of the button, g. said collar having a recess in it, adapted to register with and receive said hook when the collar is suitably turned, whereby the obstructing action of the collar is obviated.
Claim 2
Dependent Claim
151 words
An aerosol dispenser comprising, in combination: a. a pressurized container having a tilt-type discharge valve provided with a protruding tiltable valve stem, and having a valve mounting cup carrying said valve and stem, b. said cup having an annular exterior shoulder provided with an undercut, c. an annular collar surrounding said cup and turnable thereabout, d. an orificed actuator button carried by the valve stem, e. said button having a laterally extending hook which is adapted to latch under the shoulder of the cap when the button is laterally displaced to tilt the valve stem for discharge, f. said collar having inner peripheral portions adapted to engage and obstruct said hook so as to prevent discharging movement of the button, g. said collar having a recess in it, adapted to register with and receive said hook when the collar is suitably turned, whereby the obstructing action of the collar is obviated.
Claim 3
Dependent Claim
47 words
A dispenser as in claim 1, and further including: a. an overcap, and b. concealed thread means removably mounting the overcap on the collar, c. said collar having an accessible finger grip adapted to be grasped to prevent its turning when the overcap is unscrewed for removal.
Claim 4
Dependent Claim
41 words
A dispenser as in claim 2, wherein: a. the collar has a sloppy fit under the shoulder of the cup, enabling it to be canted as well as turned, thereby suggesting removal of the overcap by an action other than turning.
Claim 5
Dependent Claim
38 words
A dispenser as in claim 2, wherein: a. the collar has an annular groove in its top, extending along the outer periphery of the collar, b. said overcap having a bottom rim adapted to extend into said groove.
Claim 6
Dependent Claim
33 words
A dispenser as in claim 4, wherein: a. the concealed thread means comprises internal threads in the bottom rim of the overcap, and external threads disposed in the annular groove of the collar.
Claim 7
Dependent Claim
52 words
A dispenser as in claim 5, wherein: a. the outer peripheral portion of the collar has knurling and has a smooth circular shoulder disposed above the knurling and adapted to extend closely adjacent the exterior surface of the overcap, thereby to give the appearance of constituting an integral part of the overcap.
Claim 8
Dependent Claim
36 words
A dispenser as in claim 1, and further including: a. a finger piece on said hook, engageable by the fingers to stress the hook for releasing the latched hook thereof from the shoulder of the cup.
Claim 9
Dependent Claim
39 words
A dispenser as in claim 7, wherein: a. the finger piece constitutes a continuation of the hook, b. said hook being resilient whereby pressure applied to said finger piece causes a displacement of the hook from the cup shoulder.
Claim 10
Dependent Claim
33 words
A dispenser as in claim 8, wherein: a. a thin section is provided adjacent the hook and finger piece, enabling it to bend readily in response to pressure applied to the finger piece.
Claim 11
Dependent Claim
23 words
A dispenser as in claim 1, wherein: a. the recess in the collar comprises a notch disposed in the inner peripheral portions thereof.
