Image Number 16 for United States Patent #7350654.
A bottle security device includes an inner member, an intermediate member and an outer member that cooperate to lock the device on a bottle neck. The inner member includes a plurality of fingers adapted to fit under the bead on a bottle neck. The intermediate member slides over the inner member and forces the fingers against the bottle. The intermediate member includes a plurality of upwardly extending arms with inwardly projecting teeth that engage outwardly extending teeth on the inner member to lock the inner and intermediate members together. A key unlocks and rotates a rotatable member to separate the intermediate and inner members to unlock the device. Upon rotation of the cover cap, camming surfaces on the rotatable member engage the upwardly extending arms to move them radially outward to disengage them from the inner member.
