Claim:
A filler device sub-assembly having a manipulator for manipulating a cap of a container, the manipulator comprising: first cap gripper arm and a second cap gripper arm, the first cap gripper arm and second cap gripper arm being capable of cooperating to releasably retain a cap of a container; and means for controllably manipulating the first and second cap gripper arms comprising: an inner cam assembly; an outer cam assembly extending at least partially about the inner cam assembly, at least one of the outer cam assembly and the inner cam assembly coupled to the first and second cap gripper arms; and at least one follower associated with the inner cam assembly and the outer cam assembly, whereupon movement of the follower imparts a relative movement of the inner cam assembly and the outer cam assembly, to in turn, longitudinally and rotatably move the first and second cap gripper arms from a first position proximate to a container to a second position distally spaced from a container.
