Claims
- 1. An ink stick for use in a printer having, in combination:
- (a) a top surface and an opposing bottom surface, the bottom surface not being superimposable on the top surface; and
- (b) at least a first side and at least an opposing second side connecting the top surface and the opposing bottom surface at junctions, the at least first side and at least opposing second side being shaped so that a plane taken vertically through the top and opposing bottom surface does not create mirror images that are superimposable and the at least first side and at least opposing second side further being at least partly angled from a vertical line through at least one of the junctions such that one area intermediate the top surface and the bottom surface is a greater distance from the vertical line than at least one of the junctions.
- 2. The ink stick according to claim 1 further including a front surface and an opposing rear surface connecting the top surface and the bottom surface.
- 3. The ink stick according to claim 1 wherein the top surface of the ink stick has an inversion center.
- 4. The ink stick according to claim 2 wherein the ink stick is asymmetric when viewed from planes both perpendicular and parallel to the top surface.
- 5. The ink stick according to claim 2 wherein the ink stick is chiral in design.
- 6. The ink stick according to claim 1 wherein the one area intermediate the top surface and the opposing bottom surface is central therebetween.
- 7. The ink stick according to claim 1 wherein the one area intermediate the top surface and the opposing bottom surface is adjacent the bottom surface.
- 8. The ink stick according to claim 1 wherein the one area intermediate the top surface and the opposing bottom surface is adjacent the top surface.
- 9. The ink stick according to claim 1 wherein the ink stick has a length defined between a front surface and an opposing rear surface, the at least first side further having at least one flat portion.
- 10. The ink stick according to claim 1 wherein the ink stick has a length defined between a front surface and an opposing rear surface, the at least opposing second side further having at least one flat portion.
- 11. The ink stick according to claim 9 wherein the at least one flat portion comprises less than about 50% of the length of the ink stick.
- 12. The ink stick according to claim 10 wherein the at least one flat portion comprises less than about 50% of the length of the ink stick.
- 13. An ink stick for use in a printer having, in combination:
- (a) a top surface and an opposing bottom surface, the bottom surface not being superimposable on the top surface; and
- (b) at least a first side and at least an opposing second side connecting the top surface and the opposing bottom surface at junctions, the at least first side and at least opposing second side being shaped so that the ink stick is asymmetric in either the vertical direction when cut by a plane taken vertically through the top surface and the opposing bottom surface or the horizontal direction when cut by a plane taken horizontally through the at least first side and the at least opposing second side.
- 14. The ink stick according to claim 13 further including a front surface and an opposing rear surface connecting the top surface and the bottom surface.
- 15. The ink stick according to claim 13 wherein the top surface of the ink stick has an inversion center.
- 16. The ink stick according to claim 13 wherein the ink stick is chiral in design.
