A luggage case may include opposing sidewalls forming minor faces, opposing sidewalls forming major faces, and opposing end walls together forming an article defining an enclosed space. A line of separation may be formed in said minor faces and end walls. A first portion of the line of separation may extend along a first portion of opposing minor faces at a location proximate one of said opposing major faces and corresponding one of said opposing end walls positioned therebetween. A second portion of the line of separation may extend along a second portion of said opposing minor faces in a direction away from said one of said opposing major faces and towards other of said opposing major faces.

1. A luggage case, comprising: opposing sidewalls forming minor faces, opposing front and rear sidewalls forming major faces, and opposing top and bottom end walls together forming an article defining an enclosed space and defining a height dimension measured between the bottom and top end walls;a line of separation formed in said minor faces and end walls along which said article separates;a first portion of the line of separation extending along an upper portion of opposing minor faces at a location proximate the front major face, the line of separation also extending along the top end wall positioned therebetween;a second portion of the line of separation extending along a lower portion of said opposing minor faces in a direction away from the front major face and towards the other of rear major face;the first portion of the line of separation and the second portion of the line of separation extending in two different directions;at least one support element operably associated with said other of said opposing end walls; anda transition portion of the line of separation defined where the first portion and the second portion of the line of separation meet, a top end of the transition portion positioned at a location between 5% and 40% of the height dimension from the bottom end wall. 2. The luggage case of claim 1, wherein the transition occurs at a height of approximately 7% from the bottom of the end wall. 3. The luggage case of claim 1, wherein: the dimension between the first portion of the line of separation and the front major face defines a depth of the upper lid;the dimension between the first portion of the line of separation and the rear major face defines a depth of the upper base;the dimension between the second portion of the line of separation and the front major face defines a depth of the lower lid;the dimension between the second portion of the line of separation and the rear major face defines a depth of the lower lid;the transition portion defines a tapering angle corresponding to the increase in depth of the lower lid and a decrease in depth of the lower base. 4. The luggage case of claim 1, wherein the transition portion forms one of either a discrete angle or a curve defining a taper angle. 5. The luggage case of claim 4, wherein the taper angle is at least 20 degrees less than 80 degrees. 6. The luggage case of claim 5, wherein the taper angle is at least 65 degrees and less than 75 degrees. 7. The luggage case of claim 6, wherein the taper angle is at least 70 degrees. 8. The luggage case of claim 5, wherein the taper angle is approximately 59 degrees. 9. The luggage case of claim 1, wherein the transition portion may extend approximately 10 to 40 percent of the total height of the luggage case. 10. The luggage case of claim 8, wherein the transition portion may extend approximately 20 percent of the total height of the luggage case. 11. The luggage case of claim 4, wherein the second portion of the line of separation intersects a respective edge defined by a respective one of the minor faces and the bottom end wall at an angle. 12. The luggage case of claim 4, wherein the second portion of the line of separation extends below the transition portion and defines a lower height, and intersects an edge defined by a respective one of the minor faces and the bottom wall substantially perpendicularly. 13. The luggage case of claim 11, wherein the lower height may be approximately within the range of 0 to 30 percent of the height dimension. 14. The luggage case of claim 3, wherein the increase in depth of the lower lid compared to the upper lid is approximately 5.8% of a total depth of the case. 15. The luggage case of claim 3, wherein the increase in depth of the lower lid compared to the upper lid is approximately 18 millimeters. 16. The luggage case of claim 3, wherein the ratio of the depth of the lower base to the depth of the lower lid is in the range of from 45:55 to 70.5:29.5. 17. The luggage case of claim 3, wherein the ratio of the depth of the upper base to the depth of the upper lid is in the range of from 95:5 to 70:30. 18. The luggage case of claim 1, wherein said second portion of the line of separation extends around at least a portion of the at least one support element to position the at least one support element toward the front major face relative to the second portion of the line of separation. 19. The luggage case of claim 1, wherein said second portion of the line of separation extends around at least a portion of the at least one support element to position the at least one support element toward the rear major face. 20. The luggage case of claim 1, wherein: the second portion of the line of separation extends across the bottom end wall;at least two support elements mounted on the bottom end wall; andthe second portion of the line of separation passes between the at least two support elements. 21. The luggage case of claim 1, wherein the line of separation along the first portion is substantially parallel to the rear major face. 22. The luggage case of claim 1, wherein the line of separation along the first portion is substantially parallel to the front major face. 23. The luggage case of claim 1, wherein the support element comprises at least two spinner wheels operably associated with said other of said opposing end walls.
