A filler device sub-assembly having a manipulator for manipulating a cap of a container comprising a first and second cap gripper arm and a member for controllably manipulating the cap gripper arms. The controllable manipulating member comprising an inner cam assembly, an outer cam assembly and a follower. The outer cam assembly extends at least partially about the inner cam assembly. One of the inner and outer cam assemblies coupled to the first and second cap gripper arms. The follower is associated with the inner cam assembly and the outer cam assembly. Movement of the lifter shaft imparts movement of the follower and relative movement of the inner cam assembly and the outer cam assembly, to in turn, longitudinally and rotatably move the cap gripper arms from a first position proximate to a container to a second position distally spaced from a container.

The filler device sub-assembly of claim 3 wherein:the at least one follower coupled to the inner cam cooperates with the upper slot of the outer cam assembly; and the at least one follower coupled to the lifter shaft cooperates with the lower slot of the outer cam assembly. 6. The filler device sub-assembly of claim 5 wherein:the upper slot of the outer cam assembly further camprises a longitudinal section and a rotational section; and the lower slot is substantially collinear with the longitudinal section of the upper slot. 7. The filler device sub-assembly of claim 5 wherein:the lower slot of the outer cam assembly is oblique to the slot of the body of the inner cam assembly. 8. The filler device sub-assembly of claim 1 wherein:the outer cam assembly is substantially fixed and the inner cam assembly is capable of each of longitudinal motion and rotational motion relative to the outer cam. 9. 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 arm 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; at least one follower associated with the inner cam assembly and the outer cam assembly; and a lifter shaft associated with at least one of the inner and outer cam assemblies, whereupon movement of the lifter shaft imparts movement of the follower and 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. 10. The filler device sub-assembly of claim 9 wherein:the inner cam assembly is associated with the lifter shaft; the outer cam assembly is substantially stationary; and the inner cam assembly is coupled to the first and second cap gripper arms. 11. The filler device sub-assembly of claim 9 wherein:the outer cam assembly includes at least one slot assembly, the at least one slot assembly including an upper slot and a lower slot; the inner cam assembly including at least one slot for each of the at least one slot assembly of the outer cam assembly, the at least one slot of the inner cam assembly corresponding to one of the upper slot and the lower slot of the outer cam assembly. 12. The filler device sub-assembly of claim 11 wherein:the at least one slot of the inner cam assembly corresponds to the lower slot of the at least one slot assembly of the outer carn assembly. 13. The filler device sub-assembly of claim 11 wherein the at least one follower comprises:at least one follower associated with the inner cam assembly and corresponding to one of the upper and lower slots of the at least one slot assembly; and at least one follower associated with the lifter shaft and corresponding the other of the upper and lower slots of the at least one slot assembly and corresponding to the at least one slot of the inner cam assembly. 14.
