Disclosed are blanks for divider shelves for erecting into load-bearing divider shelves for use in cartons. In one embodiment, a divider blank for erecting into a load-bearing divider shelf having a length and width is disclosed. The divider blank comprises two center supports that are foldably attached by a fold line extending in a lengthwise direction. Each center support has two ends in which each end is foldably attached to an end support. Each end support has a top and bottom and is attached to an angular slot flap by a fold line extending between the top and bottom of the end support. Each angular slot flap has a locking slot in the mid-section between the top and bottom of the flap. The divider shelves erected from the blanks and the carton with the divider shelves installed are also disclosed.

The invention claimed is: 1. A divider blank for erecting into a load-bearing divider shelf for use in a carton, said divider blank having a length and width and comprising: a. two center supports which are foldably attached by a fold line extending in a lengthwise direction, with each center support having two ends, with each end being foldably attached to an end support which has a top and bottom and which is foldably attached to an angular slot flap by a fold line extending between the top and bottom of the end support, with each angular slot flap having a locking slot that extends downwardly at an angle from the fold line extending between the top and bottom of the end support; and b. a shelf with two leaves, with each leaf being foldably attached to each center support by a fold line that extends at least a substantial distance of the length of the center support and in a direction at least substantially parallel to the fold line between the two center supports, with each leaf being foldably attached to a locking flap with two ends. 2. The divider blank of claim 1, in which the locking slot is formed in the mid-section between the top and bottom of the angular slot flap and a locking tab is located on each end of the locking flap. 3. The divider blank of claim 2, in which a side support flap is foldably attached to each angular slot flap. 4. The divider blank of claim 2, in which a horizontal support flap is foldably attached to the locking flap. 5. The divider blank of claim 3, in which a horizontal support flap is foldably attached to the locking flap. 6. The divider blank of claim 2, in which each leaf is formed from a portion of a center support. 7. A load-bearing divider shelf for use in a carton, said divider shelf having a length and width and comprising: a. two coextensive center supports which are foldably attached by a fold line extending in a lengthwise direction, with each center support having two ends, with each end being foldably attached to an end support which is normal to the center support, with the end support having a top and bottom and which is attached to an angular slot flap by a fold line extending between the top and bottom of the end support, with the angular slot flap extending at an obtuse angle towards the plane of the opposing end support, with each angular slot flap having a locking slot in the mid-section between the top and bottom of the angular slot flap extending downwardly at an angle from the fold line between the end support and the angular slot flap; and b. a shelf with two leaves, with each leaf attached to each center support in a position normal to the center support by a fold line that extends at least a substantial distance of the length of the center support and in a direction at least substantially parallel to the fold line between the two center supports, with each leaf being attached to a locking flap by a fold line generally parallel to the fold line between the center support and the shelf, said locking flap having two ends, each of which has a locking tab which is locked in the locking slot on the adjacent angular slot flap. 8. The load-bearing divider shelf of claim 7, in which a side support flap is foldably attached to each angular slot flap and a horizontal support flap is foldably attached to each locking flap. 9. The load-bearing divider shelf of claim 8, in which the locking flap extends downwardly at least at substantially the same angle as the locking slots in the angular slot flaps. 10. The load-bearing divider shelf of claim 7, in which each leaf is formed from a portion of a center support. 11. The load-bearing divider shelf of claim 9, in which each leaf is formed from a portion of a center support. 12. A carton with three compartments comprising: a. a load-bearing divider shelf for forming three compartments, said shelf having a width and length with two coextensive center supports which are foldably attached by a fold line extending in a lengthwise direction, with each center support having two ends, with each end being foldably attached to an end support which is normal to the center support with the end support having a top and bottom and which is attached to an angular slot flap by a fold line extending between the top and bottom of the end support, with the angular slot flap extending at an obtuse angle towards the plane of the opposing end support, with each angular slot flap having a locking slot in the mid-section between the top and bottom of the angular slot flap extending downwardly at an angle from the fold line extending between the top and bottom of the end support, with a shelf leaf attached to each center support in a position normal to the center support by a fold line that extends at least a substantial distance of the length of the center support and in a direction at least substantially parallel to the fold line between the two center supports, with each leaf being attached to a locking flap by a fold line generally parallel to the fold line between the center support and the leaf, said locking flap having two ends, each of which has a locking tab which is locked in the locking slot on the adjacent angular slot flap; and b. a wrap-around closure enclosing the divider shelf to form a carton, said closure comprising a bottom panel, top panel and two side panels, each of which is interconnected with the bottom and top panels, said wrap-around closure having a length extending through all of the panels and a width, the length of the closure extending around the divider shelf in the same direction as the width of the divider shelf, the length and width of the wrap-around closure being sufficient to at least substantially enclose the divider shelf. 13. The carton of claim 12, in which one of the panels of the wrap-around closure is formed from two flaps. 14. The carton of claim 13, in which a plurality of strips are foldably attached to the wrap-around closure and glued to the divider shelf to secure the closure in place enclosing the divider shelf. 15. The carton of claim 14, in which a side support flap is foldably attached to each angular slot flap and a horizontal support flap is foldably attached to each locking flap, with the locking flap extending downwardly at least at substantially the same angle as the locking slots in the angular slot flaps. 16. The carton of claim 14, in which each leaf of the divider shelf is formed from a portion of a center support. 17. The carton of claim 16, in which a handle is formed in the end supports of the divider shelf.
