  • Patent number: 5630510
    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. The second sleeve is then heat-shrunk on the first sleeve to close the open ends of the first sleeve. Prior to loading into an ink jet apparatus, the second sleeve is removed and the flap is pushed into the first sleeve against the nugget to discharge the nugget from the open end and into the ink jet apparatus.

  • Patent number: 5602621
    Abstract: A film package including sheets of imaging media or film sandwiched between upper and lower stiffeners and enclosed by an envelope. Adhesive strips secure the stiffeners together at overlapping tabs formed on opposite sides of the stiffeners. The stiffeners with the film sheets are removed from the envelope by opening one side of the envelope. The adhesive strips also have tear strips for allowing removal of the upper stiffener after the package has been placed in a drawer of a printer with the aid of offset tabs on the stiffeners which indicate and assure proper orientation. A notch in the corner of the lower stiffener allows a signal to be passed to indicate whether the upper stiffener has been removed. The lower stiffener is also apertured to receive a signal for indicating whether any film sheets remain on the stiffener while in the drawer of the printer.
