  • Patent number: 5657908
    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.
