Abstract: An apparatus for dispensing an aerosol container's pressurized fluid contents includes a base; a first, outer sleeve mounted on the base; a second, inner sleeve nested within the outer sleeve and defining a bore adapted to receive the container; and a plurality of retainers pivotally mounted to the base within the outer sleeve so as to move from a radially inward position to a radially outward position relative to the centerline of the two sleeves. The inner sleeve is biased away from the base by a first spring, such that a first internal camming surface on the inner sleeve engages each retainer to urge it radially inwardly into engagement with the container's external curl upon advancement of the container into the nested sleeves, thereby securing the container proximate to the base. Upon moving the inner sleeve towards the base, the sleeve's first internal camming surface disengages the retainers to permit their radial expansion and, hence, the release of the container's external curl.

Abstract: There is provided, in conjunction with a container fitted with a toggle-acting dispensing closure cap, a cap-surmounting secondary control cap to render the container "child-resistant". The control cap is sleeved over and is coaxial with and rotatable about the closure cap. Bridging a generally-cylindrical skirt-like wall of the control cap is a partial, sector-like top wall which covers only a portion of the closure cap including the toggle-like actuator used to open and to close a dispensing port of the container. The partial top wall, which is provided with a restricted through opening, prevents one from impressing effective opening forces on a "press-to-open" section of the actuator. Opening forces can be applied to the actuator only by a probe acting through the restricted opening in the top wall sector of the control cap, and then only when that wall sector overlies the press-to-open section of the actuator.
