    Abstract: A solid ink jet nugget is contained in a first sleeve having opposite open ends and a flap at one open end movable into the sleeve towards the other open end. A second sleeve is placed about the first sleeve with its opposite ends directed generally at right angles to the direction of the open ends of the first sleeve.
