Abstract
Abstract A dye ribbon package for use with a thermal printer and containing for that purpose in spaced parallel relation therein a supply spool wound with dye ribbon and a take up spool for rewinding the dye ribbon as it is unwound from the supply package, a leading end of the dye ribbon on the supply spool being attached to the take up spool, each spool having a winding core with a free end portion, in which the package has a bottom wall and at each of the opposite sides of the bottom wall normal to the spool axes upstanding lateral wall integral with the bottom wall. Each lateral wall has two laterally spaced apart panels, both cut out downwardly from their edges opposite the bottom wall to removably receive the free end portions of the spool cores and permit free access to the end faces of the spool cores. The opposite sides of the bottom wall are spaced apart a distance greater than the length of the spool cores so that the upstanding outer penel wall at least partially shields the core end faces without preventing axial access thereto through the cut out in the outer wall panel. In cross-section, the lateral walls can be of inverted U-shape and inwardly sloping inverted V-shape.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
299 words
A dye ribbon package for use with a thermal printer and containing a supply spool with a roll of the dye ribbon wound thereon with a leading end extending from such roll and a take-up spool having the leading end of the dye ribbon attached thereto for rewinding the ribbon as it is unwound from the supply spool, each such spool having a winding core and axially spaced apart flanges disposed on said core at points axially spaced from end faces of said core to define axially projecting free end portions on said core, said package comprising a generally rectangular bottom wall having a dimension between opposite sides thereof normal to said spool cores exceeding the length of said cores and two lateral wall means at said opposite sides of said bottom wall and integral therewith, each lateral wall means comprising two laterally spaced apart wall panels connected to said bottom wall in upstanding relation thereto, an outer one of said two panels being coterminous with said bottom wall side, the two panels of each wall means having slotlike openings extending downwardly from open ends in edges of said panels opposite to said bottom wall in alignment with each other and with the openings in the opposite wall means for reception of corresponding free end portions of the cores of the spools with said flanges proximate inside ones of said wall panels thereby to support both spools in parallel relationship, said slotlike openings allowing easy removal of the spools from the package in a direction radial to their axis, and end faces of said cores being readily accessible axially through said openings in the outer wall panels for gripping by an operator's fingers while the core end faces are situated inside of said outer wall panels and thereby protected.
Claim 2
Dependent Claim
299 words
A dye ribbon package for use with a thermal printer and containing a supply spool with a roll of the dye ribbon wound thereon with a leading end extending from such roll and a take-up spool having the leading end of the dye ribbon attached thereto for rewinding the ribbon as it is unwound from the supply spool, each such spool having a winding core and axially spaced apart flanges disposed on said core at points axially spaced from end faces of said core to define axially projecting free end portions on said core, said package comprising a generally rectangular bottom wall having a dimension between opposite sides thereof normal to said spool cores exceeding the length of said cores and two lateral wall means at said opposite sides of said bottom wall and integral therewith, each lateral wall means comprising two laterally spaced apart wall panels connected to said bottom wall in upstanding relation thereto, an outer one of said two panels being coterminous with said bottom wall side, the two panels of each wall means having slotlike openings extending downwardly from open ends in edges of said panels opposite to said bottom wall in alignment with each other and with the openings in the opposite wall means for reception of corresponding free end portions of the cores of the spools with said flanges proximate inside ones of said wall panels thereby to support both spools in parallel relationship, said slotlike openings allowing easy removal of the spools from the package in a direction radial to their axis, and end faces of said cores being readily accessible axially through said openings in the outer wall panels for gripping by an operator's fingers while the core end faces are situated inside of said outer wall panels and thereby protected.

Claim 4
Dependent Claim
37 words
A package according to claim 1, which has a hinged lid swingable from and to a closed position to and from an open position for closing in its closed position the open ends of said slotlike openings.

22 words
A package according to claim 1, wherein each of said side wall means comprises two wall sections (21, 24) spaced in parallel.
Claim 7
Dependent Claim
46 words
A package according to claim 1, wherein at least one flange of a spool has a diameter at least equal to that of a roll of wound ribbon thereby to allow rotation of the spool by an operator while avoiding contact with the roll of ribbon.
Claim 8
Dependent Claim
18 words
A package according to claim 6, wherein said at least one spool flange has a knurled peripheral edge.
Claim 9
Dependent Claim
12 words
A package according to claim 1, which is made of corrugated board.
